Solve : Lenovo new touchpad issue? |
|
Answer» I own a Lenovo W540 with Windows 10 on it and the default touchpad is absolutley terrible. I saw that it was possible to install a new touchpad from the W541 onto the W540. The new ones are much better, so I proceded to do that. This one to be exact. http://www.ebay.com/itm/272000239170?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT |

Solve : IDE (or) AHCI on Intel Atom D510 build with 80GB SATA 1 HDD 5400rpm? |
|
Answer» Noticed after replacing 2032 battery on a board and reconfiguring the bios settings that the SATA controller was set to IDE. When looking at the choices its AHCI or IDE with IDE being the default config. I left it at IDE but was wondering that other than what I see here about the 2 http://www.diffen.com/difference/AHCI_vs_IDE are there any pros or cons to leaving it alone at IDE. The hard drive is an older laptop hard drive that is 1.5 SATA and not 3.0 speed and only 5400rpm. I cant imagine there being that much of a performance gain in switching to AHCI. The motherboard runs an Intel Atom D510. I pretty much repurposed a laptop hard drive for this ITX build and knowing that the Intel Atom was going to be not the best of performance anyways that a slow older hard drive paired with it would probably be just fine. Thanks for additional info... yeah i didnt want to switch to try it out and bork the data, so i left it alone at default.Good choice. Use AHCI if you go to a SSD. Advanced HOST Controller Interface GIVES faster transfer of data if the device can do it. RAID and SSD are candidates.

Solve : PSU cancer? |
|
Answer» My computer's motherboard broke about a week ago. However what caused it to break is confusing me. About half a year ago I had overclocked it 15% so I was assuming that I had just fried the circuitry. However, when I took it to PC world another suggestion was RAISED: the PSU can act like a cancer to the motherboard and slowly kill it over time if it is faulty. Is the theory of a PSU slowly destroying a motherboard true? A practice some techs have is to use a 'sacrificial lamb" motherboard. It is a motherboard worth less that a PSU. you hook it to a suspect PSU and see if it works and the voltages are normal. Most actually will use a Power Supply Tester so that they dont fry electronics. A power supply tester you can add loads to it and see how it behaves. Here is a cheap example. The better ones cost more and have more features for testing and loading a power supply heavily to see how it responds without burning up anything except for maybe the power supply if its weak or flawed. http://www.newegg.com/Product/Product.aspx?Item=N82E16899161001&cm_re=power_supply_tester-_-99-161-001-_-Product |

Solve : I think i fried half of the sound card of my motherboard, any fix for this?? |
|
Answer» I was trying to install my comp on a normal sony amplifier I use for my turntable and many more devices in my household. Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. They do not in themselves create an electric shock hazard, the inappropriate connections that cause a ground often result in poor electrical bonding, which is explicitly required by safety regulations in certain circumstances. In any case the voltage difference between the ground terminals of each item of equipment is small. A severe risk of electric shock occurs when equipment grounds are improperly removed in an attempt to cure the problems THOUGHT to be caused by ground loops. In the USA and many other PLACES there is supposed to be a safety ground wire on every electrical outlet. But sometimes it is not present. Then you can get a significant shock. You can survive, but audio input devices for home use can not tolerate that kind of abuse. The input limits for such devices may be as low as 5 volts and 20 mills. Output devices have a higher limit, but still much less that the 120 VAC That might be present with no grounding in place. So the OP may have blow stuff in the sound card. And even the stereo. Just for informational use. I really do not know what actually happened. |

Answer» I'm having a *censored* of a time trying to use my E7 as a modem. I'm sure the answer is complicated. Who can I call, or what site might help me? Nokia Suite is meant for most Symbian and S40 phones.Are Nokia Suite and Nokia Ovi Suite the same thing? I search one and get the other.

Solve : Computer Upgrade Vs Buying New Computer? |
|
Answer» Hello Everyone! What exactly are you starting with here i.e. Is it a branded PC or a self built? Why are you attempting an upgrade? It might help people gage what you will need if you provide some idea of what you would like your computer to do which it doesn't do now or you would like it to do better. Quote from: DaveLembke on November 05, 2015, 07:56:36 AM What model Dell so we can look up the main board to see what the board supports according to Dell? I forgot to SAY Don't buy the CPU that I recommended yet. At the moment it is literally an educated guess as to what might be compatible. We need either the computer model or motherboard model to know.Quote from: Accessless on November 05, 2015, 09:21:31 AM I forgot to say Don't buy the CPU that I recommended yet. At the moment it is literally an educated guess as to what might be compatible. We need either the computer model or motherboard model to know.To be clear, it is not compatible, totally different socket.Quote from: Lazereye on November 05, 2015, 07:17:18 AM Hey Acc, i have 8gigs of ram, i want to upgrade for better gaming, all these new games are coming out and i find myself not being able to run them, even on lowest. This would concern me, your system is by no means brand new but it's far from ANCIENT and the hardware isn't terrible. I've certainly run lower-spec MACHINES which have coped with modern games albeit on medium or lower settings. Could you give some examples of games you've struggled with?Games like, overwatch, Cod, etc On my computer right now, Processor is i3-2130 3.40Ghz System model: Inspiron 660 bios: A05 Dell incQuote from: camerongray on November 05, 2015, 11:30:01 AM To be clear, it is not compatible, totally different socket. Whoops. Well that's embarrassing... Quote from: Lazereye on November 05, 2015, 08:21:19 PM Games like, overwatch, Cod, etc Your computer does meet the minimum requirements for those games. However I don't know if that allows for online play.Basically what i was wondering is, What parts should i get, Like which i5 would work for my motherboard, and if i get a 750 nivida What powersupply will i need, and will i need a new fan? Also will i need a new case or should all this go in the same?As for your current system I think that an Intel Core i5-3570 or i7-3770S Are the two best choices as they are around the same power consumption and TDP but they seem to be hard to come by. From what I have dug up though I have found that the Inspiron 660 shiped with either an i3-2130 or i5-3330 so I would expect that one would work. You will need another member though as I'm not 100% that these are compatible. *Looks at camerongray The little experience that I have with upgrading Dell PC's is that it can be difficult. I'm basing the compatibility on an Intel mobo with the same chipset. But I have no idea if Dell ever updated the BIOS for their motherboard to allow the use of them. The real kicker is that the older CPU upgrades and the newer CPU's (that you will need a new motherboard for) cost about the same and deliver the same performance (so the newer stuff would be more expensive when adding on the cost of the motherboard).All this speculation means Zilch since we still don't know what Mboard you have... |

Answer» Every time I turn my laptop on, the screen is black, static/ocean wave sound comes out of audio, then it shuts itself off. Its an Acer Gateway laptop and i just recently had to get all the hardware replaced due to me accidentally dropping it. Is there a way for me to fix this problem and without having to pay to get it REPAIRED once more? Are you sure its the speakers making this noise and not a fan that is grinding inside or HARD drive? Such as if you connect the audio jack on the laptop to a heatset do you HEAR this direct to your ears? |

Solve : Unauthorized Battery Detected? |
|
Answer» Does anyone know what Windows 8 would be basing an error message about an "Unauthorized laptop battery" on? Does anyone know what Windows 8 would be basing an error message about an "Unauthorized laptop battery" on?Such a message can be the result of problems with battery detection. Laptop batteries have a chip in them that IDs the battery. I have heard of it happening with Lenovo products. Probably happens with others. Often it is necessary to go in the BIOS. I suggest posting in a forum specializing in the actual brand/model. Sorry I forgot to update this thread. All solved now. Much to my "surprise" the laptop in question is a Lenovo (Formally IBM. IBM makes these pieces of s#!+ !?) The laptop comes with hardware management software. As is turns out if you forget to update the software it declares your battery as void and refuses to charge it. A simple software update resolved all problems. Thanks for the help. P.S. I have since discovered that the laptop is suffering from a serious case of Windows 8. I'm not sure that I have the technical expertise to resolve this. |

Solve : AC Powered Speakers? |
|
Answer» Just got new Amazon Basics A150's. Very nice for the price. Instructions did not say if it is ok to leave speakers on all of the time or if they should be turned off. I recall reading somewhere that they should be turned off. Doesn't seem like it would make much difference but thought I should ask. Thanks.I leave mine turned on all the time. I pull the AC plug out when I go on vacation or away for a few days. The Consumer Product Safety Commission, using estimates from 2006 through 2008, says that major appliances caused more than 150,000 residential fires each year, resulting in 3,670 injuries, 150 deaths, and $547 million dollars in property damageBeen using AC powered speakers for over 20 years and no problems. It seems like the people you use the volume control or power button on them have more problems with their failure due to physical wear on them. Additionally I have all my equipment powered behind a battery BACKUP that cleans the power to the computer equipment and keeps it smooth to avoid spikes and power outages to equipment when power is out for less than 20 minutes.The AC powered speakers often have an external power unit. These are often called "Wall Warts" because of how they look in a electrical outlet. Many , maybe most, of these are made in other countries. They have to pass some kind of testing before that can be sold. They gt a "U-L" SEAL of certification. Still, that does not mean they are absolutely fireproof. The greater danger is putting these devices in an area where there is limited VENTILATION and combustible materiel. Every year some fires are started by a "Wall Wart" AC adapter. In a few cases damage was huge. The link below indicates electrical fires were a significant part of home fires in recent years. But is does not identify specific devices. Most reported are bad use of cords and bad wiring. http://glowingconnection.com/faq.html But here is a very specific item. Apple adapter catches fire, on film Quote This is a known defect with Apple power adapters, I think - it's happened to me as well. The cable wears as it gets bent back and forth during use, and the wires inside break, and next thing... smoke. And, sometimes, flame.So, don't leave you iPhone overnight. I unplug mine when I go away because my household insurance demands that I unplug all "unncessary appliances" when away for more than 24 hours. Quote I unplug mine when I go away because my household insurance demands that I unplug all "unncessary appliances" when away for more than 24 hours. wow ... never heard of an insurance company specifying this verbally or even in fine writing. Is this DEMAND only because you have a very itemized liability listing that makes you claim to be just a small amount safer ( lower risk to them of having to make a claim ) than others such as in the USA you can itemize vs paying for a base insurance and claim your not a smoker etc and save based on that etc. Only problem with this route of itemization to save money is that if someone stopped by and was a smoker and set your home on fire the insurance company could say sorry its your problem. So if you forget to unplug the electronics for when away on vacation and something happens and investigation finds that you forgot to shut off answering machine that has a wall-wort they can say sorry charlie you violated the agreement and so your out of luck by a large amount of money that would cripple most people financially.Quote from: DaveLembke on November 02, 2015, 08:09:48 AM wow ... never heard of an insurance company specifying this verbally or even in fine writing.I asked my wife, who told me that, and who pays for the insurance, and she checked the documents. We found they actually don't say you have to unplug anything when away to stay covered. There was a leaflet of fire safety tips ALONG with the policy documents, and that suggested unplugging things while away in case of a surge or a lightning strike, but it's not mandatory. |

Solve : Custom PC, won't boot, Overclocking Failed error when no attempt to overclock.? |
|
Answer» About 5 months ago I decided to build my first custom rig, specs are as follows... Why do you ask?You would be surprised how many times computers get "fixed" or "improved" or have games/malware etc installed by someone other than the owner. Often it is a young adult or TEENAGE (or younger) male person. However, if you can exclude that possibility, then I agree with PATIO. SINCE your motherboard is 5 months old, you should be considering a warranty claim. What I ended up doing was a full reset, If I have any further issues I will take your advice. Thank you! |

Answer» My sister gave me her old laptop. I changed the CMOS battery. The display screen is not working. I have it plugged up to an external screen. It shows this "The firmware has detected that a CMOS battery failure occurred continue". I tried hitting f1 and nothing happens. I have tried f2 after pressing the power button but it won't let me change the time or date that way. I have heard people talking about resetting a jumper or shorting a circuit, but I have no clue how to do this. I have to do all this myself because I am flat broke so I can't pay anyone to do it for me. I have a Toshiba Satellite L655D-S5050. Any help would be GREATLY a appreciated.Double check to make sure all ribbon cables are installed correctly. There is a top and bottom to them. One side has the contacts and the other side is smooth plastic. I have seen before where people insert the ribbon cable upside down and lose their keyboard functionality where it worked prior to opening. |

Solve : New computer hard drive question? |
|
Answer» I ordered a NEW pc and my old pc has a bad motherboard...Can I just put my old HD in the new pc if they are both sata so I don't have to copy all my stuff?You can do however you won't be able to properly run your OS or programs from the old disk, they may work but will likely cause issues. There is however nothing wrong with booting from the new PC's HDD and then purely using the old one to access your old files.If your only goal is to obtain extra MEMORY for your new PC (which I assume is the case) then yes you can, although it is best to COMPLETELY erase all of the data from the drive before adding it to your new PC. If you WANT to keep some of the data I would suggest TRANSFERRING only what data you need to another drive then erasing the old one and adding it to your new rig. Hope this helps!What Win version are we talking about here ? ? |

Solve : General HPC high performance computing Question? |
|
Answer» I am building a Supercomputer made out of 4x 16 core machines running at 2.93 Ghz, stock. I was wondering if the head node for the cluster is required to have any performance characteristics? I mean to say, should it be a good computer? Will it matter if I throw on a cheap pentium 4 or will I be better off with a duo core or ever duo core with hyperthreading etc.... The idea is that the head-node relays info from the workstation, and therefore isn't too important (spec-wise), is that right? You should definitely be using a gigabit network for this but you probably don't need any separate network cards, just use the onboard ones and a reasonable Gigabit switch. Not much experience of clusters so I can't comment on the rest but just wanted to agree with this. Those boards have a pretty good dual-port Intel Gigabit Ethernet controller onboard, I can't imagine you'd need anything better so I wouldn't look at dedicated cards.What can I do with the two ports? Why would it even have the two? Does it have something specifically to do with the 1 gigabit router? Would connecting one to another in a series fashion work for something (just idle curiosity)?Dual Ethernet is for NIC teaming and redundancy. NIC teaming allows nearly doubling of throughput (usually you just have to plug both into a switch as long as all the hardware supports the appropriate networking standards), redundancy, because there are two of them. |

Solve : Server Mobo with Correct PSU won't turn on? Is it the right one?? |
|
Answer» I bought some used items from ebay to attempt a build of a small server. The parts I chose were: That might not be sensible but I don't have to be!Here's some additional information about 12 volt power. Industrial power supplies may have several 12 V connections. The hobbyist should understand why this is a common practice in the industry. Is not just simply a case of getting more current through the wires and connectors. Rather it has to do with stability of the system. The switching power supply can have any number of outputs. Each output is a separate SUB assembly that delivers the desired voltage to a pair of wires. The sub assemblies do not all have to be grounded together. The return wire can go out to the motherboard and at the motherboard it is hooked to the common. For the amateur enthusiast the reason for this may not be obvious. But there is an issue regarding stability. By having each unit with separate ground return wires it improves the stability of the system as there is less interaction between different devices that suck power from the 12 V lines. Or, to put it another way, it helps reduce the voltage swing on each supply. That's why they do it. If they needed just a huge 12 oh power supply, that is what they would build. But for the computer stability is very important. Small VARIATIONS in voltage can cause unreliable operation in some parts of the system. By using separate 12 volt sub assemblies, the stability can be kept within 2% or even better. What I'm trying to say is this. If the design calls for 12 V in four different places on the motherboard, you have to have a power supply that does deliver the four 12 volt independent power from sub assemblies. Some hobbyists have posted another places that you can just simply type all the units together and hook up to a huge 12 V power supply. That's not true. It was not designed that way for a reason. It has to do with stability. Muck around and try some hacking and you'll end up with something does not work reliably. Just for INFORMATIONAL purpose. . |

What should I do?You will need to get a better power supply - Not having the suitable pins MAKES me think that it was NEVER designed to drive as high powered a card as the R9 380. Do not risk adapters, they can totally throw the load on the PSU off and damage components, not worth the risk.I am not an expert but you could try a solution I have found as useful in the past. |

Solve : Games/ OCCT PSU test rebooting PC ( PSU Problem?)? |
|
Answer» As the title says my PC started rebooting during games, and after running many stress tests and following suggestions, I finally found a WAY to replicate the problem. When I run OCCT PSU stress test, my PC reboots within a second. It was unexpected since running Prime 95 together with Furmark didn't cause any reboots. ... Anyway, do you think the issue is my PSU (corsair hx750w)?...Yes, unless you have a way to prove the PSU is working normal. Do you have any basic tools like a digital voltmeter and some material from an old electric heater? The wire in the heater can be used as a load to test the PSU. What is the rating for: 3 volt lines 5 volt lines. 12 volt lines I found this: Quote 100 - 240 V 47 - 63 HzThat would be about 80 watts plus 125 watts plus 744 watts. Build a resistor with 0.12 ohs ( for the 3 volt line) 2.5 ohms (for the 5 volt line 2.0 ohms (for the 12 volt line) Be careful! the wire will get real hot. All you need is for the PSU to hold on for three seconds. When you go over 750 watts the PSU should kick out by the thermal overload semspr. Check to see if the PSU fan is running slow. Easy fix. If this scares you, find a friend who understands this. EDIT: This information explains how to use Nichrome Wire. http://cecs.wright.edu/balloon/images/2/22/Nichrome_Wire_Heating_Element_Design_Basics.pdf The wire will fail at currents above 15 amps for more than a few seconds. So you have to use four or five wires together to lower the current in each wire. Or have some kind of ceramic core to dissipation heat.Please do not do what is described above, it is dangerous and should not be advised here. What you really need to do is find a known working PSU and try that instead. Also BEAR on mind that the Corsair HX series have a very long warranty period so it is more than likely that yours is still covered should you need a replacement. Camerongraym You are right. I went too far. Direct substitution is by for the safe ans sane why to test. Extreme electronic testing should only be done by people who have been trained the kind of stuff. You could get hurt very badly. And you need a workplace. Image from http://gtri.gatech.edu/facilities Just trying to help... Sorry, for not replying before . I created this topic in multiple forums to increase chances of getting a response and stopped following this forum by mistake apparently. I will definitely bookmark this right now, so it won't happen again. I am an electronics engineer, though we never were assigned to work with anything that could hurt us. So I am not sure I want to test the PSU myself, as Corsair already approved my RMA but I want to avoid wasting time and money to send it abroad (not available in my country ) if possible. The voltage readings are within 5% according to software, but if you think they don't have enough resolution I can actually measure with a multimeter. I thought the issue was resolved 10 days ago after I reassambled the PC, and changed PSU sockets and connectors with spare ones. Also bought a new surge protection extension lead. Didn't know which was causing the reboots, but it stopped rebooting as soon as I started running OCCT, and the games seemed to work fine in my limited testing. I got my new MSI gtx 970 gaming 4g 3 days ago, run some benchmarks (Heaven Unigine) etc. to make sure it works. But when I tried playing Star Wars battlefront today, my pc seems to reboot occasionally during game menus but never during the actual gameplay. I monitor CPU and GPU temps and they are always below 60 C. I read my graphics card may cause instability while transitioning from load to idle due to sudden voltage drops but it shouldn't result in a reboot as far as I know. ( https://forums.geforce.com/default/topic/784294/geforce-900-series/boost-feature-causes-gtx-970-980-instability-in-low-utilisation-situations/2/ ) I just started playing witcher 3 to see what fps I will get, now I will try actually playing the game to see if I get reboots in this game as well, and update this thread. Weirdly I am now suspecting my CPU may be causing the reboots. I was reverting every change I MADE since the PC seemed to work last, and one of them was reducing CPU cooler (Themaltake FRIO) fans from 100% to %70ish. I thought this was okay as CPU core and GPU temps were always below 65 in games with the new 70% setting. But after recent reboots there were some kernel power events with "thermalzone" in their description in the event viewer. Anyway I increase the CPU fans to 100% again, and haven't got any reboots within an hour. Of cource if I try OC ing the GPU again, I get reboots within minutes. ( CPU overclock is fine though) Could it be that increasing GPU power usage cause fluctuations in the CPU voltage and increase the CPU package temperature which is casuing reboots? I forgot to put the washers between the cooler and the motherboard while installing the CPU cooler. It was without the washers since I had the PC, and the temperatures seemed fine, so I thought they were not really necessary. Next reboot I get, I am reinstalling the cooler and putting the washers. Personally i'd walk away from OC'ing...not worth the estimated 10-12% performance increase for all the headaches... Just my thoughts...Now I also have to use the CPU cooler at max settings apperantly. Or at least 70% isn't enough, and FRIO is insanely loud above 1800rpm. Beats not being able to play at all I guess.It probably was the Cstates. Enabled c1e and disabled c3e and c6e. No reboots so far. Guess I shouldn't have trusted the guides, some even official, saying I should enable c1e and leave others at auto. The latest BIOS had one of c3e and c6e at disabled. It makes sense as fully loading both GPU and CPU at the same time didn't cause issues, but since games put varying load at cpu and gpu at different times it was probably causing problems. |

Answer» By the way, your first post SAYS you GOT an error when installing the OS. What was that error? And how long does it take the SYSTEM to boot?it was (The partitions on the DISK selected for installation are not in the recommended order). And to be hones all of a sudden the laptop is doing just fine now the last couple of restarts and the wake ups were ok. Who knows maybe just decided to do ok. |

Solve : Hard Drive Cache Question? |
|
Answer» Is there a noticeable difference between a hard drive performance with 2MB Cache and 8MB Cache. Drives of same storage capacity 160GB and same speed 7200 RPM? Maybe I just need to connect it as an extra drive and run a benchmark on both and compare that way, however the system only has 2 SATA ports and the other is used by DVD-RW. You could temporarily disconnect the optical drive while you run the benchmark, or you could buy a cheap SATA 2 PCI card and get 2 more SATA ports. Thanks for your opinion on this 8mb vs 2mb cache. I was THINKING it prob wouldnt amount to much myself. |

Solve : Incompatible RAM Issue? so confused? |
|
Answer» Hey guys! Did you already see this? Perfect thank you! So the incompatible ram can cause the lack in display ? Quote from: camerongray on October 27, 2015, 10:32:15 AM I can't see any reason why that RAM would not be compatible - Have you tried one stick at once to rule out one of them being bad? Have you tried the machine outside of the case to rule out any sort of shorts and have you tried a different power supply in case that is the problem? Are BOTH power connections to the motherboard connected? I have tried and retried all of what you mentioned Yes, I had many issues with a certain motherboard by using simple Corsair RAM. I thought, to myself, Corsair RAM seems like it should be good for use in any system. It really turns out that unless you have a new consumer board and such, you can run into issues very quickly. Getting the right ram can make the difference between posting+installing os and not getting anything at all! |

Solve : External HDD making sounds and not detected by pc? |
|
Answer» My Western Digital 1.0 TB external HDD makes noise when powered on. Spins up and down( I guess). Not detected by computer. It works sometimes after powering it on and off several times. It's connected using a sata 3.5 to usb adapter with separate power supply and connected to my laptop. whats wrong in it ?? -It would only apply with a very specific sound that is not present now. -It suggests taking apart a Hard Disk Drive to effect Data recovery. Since the issue is unlikely to be a "stuck platter" as the noise is nothing like that in the video, it would be incredibly unwise to do so. -Once it's taken apart in a non-clean-room environment the drive cannot be trusted to store anything at all. if the issue is only the Power supply- as it seems to be- the drive will be rendered useless trash. Shaking the HDD is kinda a really bad way to get it going...it's dying/dead...replace it.The drive is OK. Quote from: Geek-9pm on October 15, 2015, 04:05:32 PM The drive is OK. What ? ?Quote from: patio on October 15, 2015, 08:19:21 PM What ? ?The drive clanks because the iItty-bitty PSU can not give it start up current. All he needs to do is either measure the voltage or else use another portable PSU. I have had this problem with THREE good drives that have to kick start. Each connected to a robust PSU do not clunk at all. They just spin up. and work. Windows will not 'see' a drive until it is ready. |
