Solve : H P G60 -630 US notebook windows7, 500GB-HD, starts, with blackscreen.?

Answer»

2 year old hp g60-630 US, Factory installed OS Windows7,processor type Pentum (R) Dual core CPU [emailprotected] total memory: 3073MB, Bios version :F.63, hard drive 500GB hard drive, Intel (R) ac82GL40 Graphics Memory Controller Hub,starts with black screen, laptop fell on its power cord while in use, since then problems,with power light while connected, and battery went bad, error log 0601, I opened it to check power jack and appeared to be good, while open I cleaned the dust from fan,not clawed, but air exit screen covered with dust, but is clean now,I opened the power cord by the end where it connects to the laptop power jack and noticed it broken and separated connections, cleaned the hard clear plastic and soldered the connections has 3 and I soldered 2 broken and power light stays on now.At the time I powered up screen with 3 rows from hp showed.
I tried every step in every row of the 3, without being able to go past any of those 3 rows to next step(it just wouldn't get me to the next step, I forced shut dawn and started again with same results about 3 times, until black screen showed up).results ;stat up test 100% of the system memory tested OK 30,113,730,048 by test of system memory OK. Memory test PASSED.Primary hard disk self test Quick test executing 64% complete. appeared to stop.#1008-replace hard disk 1 rent test item(in red colored letters). run smart check ,smart hard disk passed.
Administrator:X:\windows\system32\Cmd.exe Microsoft windows version 6.1.7600.7 full test is executing 60%complete........( it stop working)#10008- replace hard disk 1 rent test item, smart check , smart hard disk passed,"hard disk failed" "hard disk 1 quick"(303) inside h20 set up utility rev.3.5 diagnostics hard *censored* fail and it was before a black screen and I opened up again checked connections and no change, YES there is one now I will not hear the fan when power is on , light for power is on and light for battery is on in front and by power jack but fan will not work and PC gets hot by under where the PCU is located and I did clean and replace the paste for PCU and FAN.
From BAD To WORST. I tried the hard drive in a Toshiba laptop and worked, showed up with hp logo and ask to get to its' original state and did it. in the Toshiba laptop as the primary drive worked or on an external enclosure with USB worked fine. But confuses me because the laptop was not showing any problems other than battery or power cord/jack to begin with and before disassembling. How can I find what is wrong?
I thank you for reading and will appreciate any help.
It is very possible I grabbed the motherboard with my not grounded hands but don't know how to check for than or know what tool is used for it what it looks like or the cost if that could be my problem I will need help there too. Thanks.

Good evening

If you are still looking for an answer please read below.

#1. If i am understanding you correct when you plug the AC cord into the laptop the light stays white? and doesn't flicker on and off when you wiggle it?
#2. That model HP does not have the drive shock protection for the hard drive (this is some bad news)
#3. Even if you put the hard drive into an external hard drive case and you can access some files on it it doesnt mean the the sectors the OS needs to boot are not bad from the drop.
#4. If all you get is the white light next to the ac plug, and nothing on the screen than the VIDEO chip has broken free from the BGA grid and must be re-flowed / re-soldered

If i can help any more please let me know, Mike Mike, Thank you for the information.
#1 Yes it is the situation at the time of my fist post.(the light use to flicker but I cut open the end of power cord where it plugs and solder 2 broken contacts(out of three) and light stays on now and power button with continuous light meaning I have power in to the computer).
#2Yes is bad news. But also good news, because I had run out of ideas as to what the problem might be until you have giving me this information .Thank you.
I really appreciate you giving me an area to look for a problem and I will work on the video ship to resolder it. I will let you know the out come once I have work on it. Do you Know which is the best tool to do it, other than sending it to a professional?
I have seen videos 1).where a pencil torch is used to resolder, 2).also a hot air gun directed on the video ship to resolder, and 3).a replacement of the videoship using computer assisted machine, the temperature is controlled from top and bottom, a light concentrated on the video ship area. 3 must be the best, but also sounds most expensive.
I do not have any of those tools, and that is why I ask, so that I know which one to look for, pencil torch or hot air gun?
or a more efficient way?
#3 The hard drive I did install it in my Toshiba Satelite L300 and reformatted it to its original new state, and place it back in to the HP with no results on fixing the black screen, I used it on the external hard drive with the Toshiba lap top and hard drive is working but I have no idea how to find out, if it has bad blocks caused by the fall, "it is the video chip what I must concentrate on for now", and hard drive latter when the video chip is fixed but I have a fling I will have trouble recuperating the old data from it.

Something has broken in the fall. Probably best to take it to a professional.

Everything else you have stated is very difficult to understand, but it seems like you repaired the power cable successfully & the hard drive is functional.Good afternoon donoscar

OK I must give you credit on what you have done and what you want to do.

#1... Yes a lot of of folks have seen those video's on the "re-flowing" etc. when and if this is done is a very temporary fix and I do mean temporary.
#2... Honestly if the laptop is out of manufacture warranty and if in deed this is the issue the "real and long term fix" is to have a Pro either local to you or a company online and spend an average of 100 to get the video chip re-balled. I am speaking from experience nothing beats getting the MoBo Video chip re-balled vs re-flowing

The reason why at home this can not normally be done the MoBo must be heated slowing to about 200 - 225 deg and then a hot air unit (either HAND held or attached to machine) must heat the chip slowly to about 225 deg then the chip can be removed. But this is only part of it. Now the MoBo BGA grid (balls or solder) must be un-soldered / cleaned then if the same must be done for the video chip.

Then a stencil and holder need to be used for placement of the new solder balls. To give you can idea about the solder balls they range from "0.020 all the way up to 0.080" now depending on the video chip there will be from 100 to 700 hundred balls in that little chip. The video chip it self is only about 1.5" square and the spacing in-between the solder balls is about 0.075". There is no room for ERROR here. Now even when the chip has the new solder balls the MoBo heating and Video chip heating must be done again. Then the MoBo must be cooled down.

This just to give you an idea of the the process. I would not suggest doing this at home.

Hopefully this will help you Thank you for explaining how important it is to have it done right by a lab or equipped shop.
I personally appreciate the detail about the amount of pins size and separation between them,Thanks.
Coming from an experienced person I will take your advice.
Can I ask if a new mother board is considered as a good option in this case?
specially hence the computer was drooped while in use and prices do vary on the same product different sellers.

I better understand what my decisions should be focus on.
Thank you very much.

From what you have stated, you have video, so why all this talk about reflowing the video chip?Hello again donoscar

In my opinion the video chip did brake free from the MoBo but I could be wrong but in order to give you an idea of cost for the board there is of your model 21 product numbers ie like wa574ua etc.

Look at the bottom of the laptop in the white label (not the MS sticker for windows) and you will see a Model number or product number like VU743AV or like WA574UA etc. Once I have that i should be able to find the MoBo part numbers.

Talk to you soon, Mike thank you .
I did try every one of the choices on the screen at the time I had video, and none of them will get me to the next step, it wouldn't take me pass that point, reason why I took it apart to clean and to see if I could find anything out of place, but it is after that, the black screen showed up and my limited knowledge will not take me any further. Only a black screen. But only that.

Your advise on taking it to a professional is holding very strong. But I'm also trying to learn which I'm doing with your help.
Thank you.product WA573UA#ABA

Thank youHi Again donoscar

I do have a couple more questions for you sorry it is so hard to get any king of description of a issue or fix thru a post.

#1... Do you have a monitor that you can plug into the laptops VGA port if so plug it in and turn on the laptop if you can see your normal desktop it is not the Video chip but the LCD screen or the inverter at the bottom of the screen.

#2... If you did take the laptop completely apart and after the LCD was screwed back down the laptop base do you remember plugging in a plug on the left SIDE on the laptop base (a lot of G60's have the LCD plug on the left

http://t1.gstatic.com/images?q=tbn:ANd9GcQgz4ej0e4-FTgCLkqTHtvl7feHJRpFZ8FHxgSwkyzAC_2121wRdw

#3... not being a wise guy but are you sure the screen is totally black if you look really close at the screen can you see faint images of your desktop?

#4... Out of curiosity when you turn the laptop on is the hardrive light blinking on and off like it is trying to boot or are you hearing windows sound(s) like normal.

But when you have a min please look on the bottom of the laptop for that sticker and get the PN / Model number.

Thanks a bunch Mike Hi Again

Ok Here is your systemboard / motherboard part number 578232-001 when Googlin it the prices range from about 120.00 on up (to buy) plus S&H companies that do the re-balling ave about 100.00 plus S&H

So it is pretty close in price, Even myself I have a G60 series here but just a different model and the better half has been very happy with it. I also have a DV7 and I like it, plus I have a Dell inspiron 1525 and this units works ok for my portable work PC.

But if you do decide to buy a MoBo just make sure you give them the G60 number, the product # and the MoBo part number so you can be sure you are getting the correct one.

But if you are looking for an opinion on fixing it / repairing it here is a way to look at it. Probably under (going higher in price) 200.00 if you like the PC and it has been good to you it is still cheaper than buying a new laptop. Even a cheapy laptop is going to be 350.00 +

Well hopefully this give you some to things to think about but I am curious to see if plugging in an external monitor worked or not from what you are describing it won't.

Mike thank you very much.
I will try to find the connector to plug in an external monitor.
it will not be today but very possible during the week and will get back to you.
Thank you very much for looking it up.
most likely I will end up buying a new MoBo.
Thanks for the info and tips. To every one Quote from: donoscar on July 22, 2012, 02:48:52 PM
...I will try to find the connector to plug in an external monitor...
Connector is standard 15-pin VGA connector, on every monitor made in the last 15+years.thank you again for telling me, the one fitting I have for desk top it looked to be bigger than the one in the laptop but you are right it did fit but screen is showing black.

Now I have try the external monitor with the same result black screen.

Thank you for pointing it out because I was going to look for it.

The fact that it doesn't have holes for screws must make it appear smaller.

Any ways now the only solution for me is going to be A new MoBo because it makes more sense than having it fixed with the chance of something else coming up wrong in the mother board.

And this also makes it as a solved trouble pending I get the new MoBo on it.

Guys you where a great help and I will post my result once I get the new one on the laptop.
