PC turns on by itself!!!

by nickelarse / January 14, 2008 11:30 PM PST

Ok, now i am desperate, i have searched loads of forums and cannot find out why my PC randomly boots up in the early hours of the morning...

First things First

OS = Windows XP MCE SP2
AMD 3400+ 2.4Ghz
4 internal HDs

OK, i was running XP X64 PRO for 1 and half years with no such random boot ups. I formatted the other day and put on the media center edition of XP. Since then i have the random boot up problem. At between 7 and 8am my PC will proceed to boot up from hibernation. Now its a complete fresh install so definitely not a virus or trojan.

I checked all BIOS wake settings...all disabled, and like i said my PC with X64 has been fine for 1.5years and i havent changed any BIOS settings.

I also installed a BELKIN wireless network card just before i formatted with new OS. Maybe something with this could be triggering...but like i said all BIOS wake settings disabled...

I am seriously stumped by this problem....if anybody could shed some light onto my problem.....i would be eternally grateful.

thanks Nick

Check The Device Manager Settings
by Grif Thomas Forum moderator / January 15, 2008 12:13 AM PST

Open the Device Manager, click on the + sign next to "Network Adapters", then RIGHT click on the new Network Adapter device, choose "Properties". When that opens, click on the "Power Management" tab, then UNCHECK the "Allow this device to wake the computer out of standby", or something similar.

Hope this helps.

anotehr option
by AceCT-2214807889169935659 / January 18, 2008 1:05 PM PST

another option is to go into the BIOS and disable Wake On Lan. Don't mess with the BIOS if you aren't comfortable though.

Did you check your scheduled tasks
by PudgyOne / January 15, 2008 5:48 AM PST

Scheduled tasks will wake the computer from hibernation.

Start/accessories/system tools/scheduled tasks

Also, I remember that someone once had the computer turn on when the phone rang.

Just to say thanks guys for your help...

I figured it out, i checked the EVENT viewer log and it showed the MEDIA CENTER downloaded its updated TV guide every morning ay 7.21 am....

Now there is no way at all change the time within MCE, you can disable auto update, or you use this free tool to change the time to whatever you like.

NOTE it can only fetch out of standby and hibernation....NOT SHUTDOWN.

I hope this helps someone because i looked over the entire internet and couldnt find any info on this....

Thanks again.

Its just Media Center
by climber109 / January 18, 2008 2:01 PM PST

Your are running XP Media Center Edition. This is normal. Media Center is supposed to come on to do TV recordings and updates. I would just suggest that you go to "control panel" -> "power options" and tell the computer to go back into standby after 15-30 minutes of inactivity.

The most beautiful phone ever has one wildly annoying issue

The Samsung Galaxy S8's fast speeds and fantastic curved screen make it a top phone for 2017, but the annoying fingerprint reader could sour your experience.
