Solve : computer turns on by itself? |
| Answer» <html><body><p>I did a search for this problem, <a href="https://interviewquestions.tuteehub.com/tag/saw-344192" style="font-weight:bold;" target="_blank" title="Click to know more about SAW">SAW</a> an idea about checking bios, haven't done it yet.<br/><br/>The computer turns on by itself in the middle of the night. It won't do this during the day. I've got to where I unplug everything when I'm through with the computer for the day. When I plug the power cord in the next day, the computer lites-up, when I turn on the monitor, the screen saver is running.<br/><br/>I had the harddrive fail recently, replaced with harddrive out of another computer. Everything works ok, I didn't have this problem before the harddrive failed. Any ideas? thanksPlease post your computer specifications.<br/><br/>I'm guessing your are running Windows Vista and here's my thoughts as to why:<br/>Many people are 'fooled' by the 'power off' <a href="https://interviewquestions.tuteehub.com/tag/symbol-345081" style="font-weight:bold;" target="_blank" title="Click to know more about SYMBOL">SYMBOL</a> at the bottom of the start menu. This is not a power off feature and is instead a stand-by button, to properly shut down you must click the arrow pointing towards the right and click shut down.<br/>The computer may of gone in to stand-by then when you move your mouse (or plug it in the next day) it comes up to where you left it.<br/><br/>That's only a guess though and will be totally blown to pieces of you run Windows XP for example. <br/><br/>Regards,<br/>Sean.The computer is an old dell P3, windows XP home edition. When the hardrive failed, I had another computer sitting here with a good harddrive so I swapped the harddrives. Everything seems to work ok, except now, the computer seems to want to turn on by itself, in the middle of the night. <br/><br/>The harddrive that failed had windows XP corporate edition, I believe. The harddrive in there now is windows XP home edition.<br/><br/>I had a computer that came on by itself. I kept it unplugged for 2 years while I wasn't using it. Then my modem went bad and when I replaced it, the computer never came on by itself again. So, it could be your modem.It sounds like "Wake on LAN" is enabled on your computer. <br/><br/>Right click "My Computer" (either located in the start menu, or on the desktop). Click Properties<br/>Click the "Devices" tab, and click the button titled: "Device Manager" <br/><br/>Find (under "Network Adapters") your Ethernet card. It should have the numbers 10/100 or 10/100/1000 next to it. <br/><br/>Doubleclick the network adapter. <br/><br/>Go to the "Power Management" tab. Un-Check "Allow this device to wake the computer" <br/>Check ""Allow the computer to turn off this device to save power" <br/><br/>Click Ok. <br/><br/>Restart your computer. <br/><br/>See if this resolves the issue. <br/><br/><br/><br/>Possible causes: <br/>"Wake on LAN' enabled by Windows or in your BIOS<br/>"Boot up at: ##:##" enabled in BIOS<br/><br/><br/>In the even that this advice does not help, please tell us:<br/><br/>Do you click "Hibernate", "Shutdown", or "Standby" when you click the shutdown button on the start menu?<br/><br/>If you use "Standby" or "Hibernate" it could be allowing your computer to power back up due to the differences in the shutdown <a href="https://interviewquestions.tuteehub.com/tag/procedures-15993" style="font-weight:bold;" target="_blank" title="Click to know more about PROCEDURES">PROCEDURES</a> that take place. I would <a href="https://interviewquestions.tuteehub.com/tag/recommend-1180268" style="font-weight:bold;" target="_blank" title="Click to know more about RECOMMEND">RECOMMEND</a> just using "Shutdown" if the problem still occurs after trying the advice above. I apologize for not responding sooner. I did look at the (power management) as you suggested. There were three boxes all checked, had to do with, standby option.<br/><br/>I never use standby, when I'm through, I use the shutdown button.<br/><br/>I haven't checked bios, not sure how? thanksyour computer may have a schedule to start up at a certain <a href="https://interviewquestions.tuteehub.com/tag/time-19467" style="font-weight:bold;" target="_blank" title="Click to know more about TIME">TIME</a>, mine used to have the same problem, i messed around in startup command prompt wndom thingy...and found a way to turn it off...im not sure how i did it i dont remember,,perhaps some nice helpful guy( or girl) mite tell u how?</p></body></html> | |
