Computer Turns on by itself[surprise]

[Deuce199]

Hey all,

Got a question, never seen this before, My computer turns on by itself when the power goes out and comes back on. The power switch is completely turned off, but after the 30 seconds of no power, and then power again the computer just starts up!

Any Help would be greatly appreciated as to why this does this.

Thanks,

Check your Bios for a setting for resume after power loss,

 

[zen2002]

Also in Bios check wake on Lan,Wake on Modem and disable both

 

[Deuce199]

Sorry guys, THere is no selection for resume after power loss, or wake on lan or modem, any other ideas?

What type of MB do you have and do you have the manual for it? if so read thru it there is so type of reference somewhere

 

[zen2002]

Have you got anything on a shedule setting such as your anti-virus or other app ?

 

[Deuce199]

Buckeye - It is a noname motherboard, and I received the computer from a freind and they say they do not have any books for it, so I can't do anything that way.

Zen - No I do not have a scheduled tasks.

May have a wake on mouse or keypress event. If you do not like my post feel free to point out your opinion or my errors.

Doube check the bios. That sounds exactly like the setting of what to do after power loss.

Sorry for the late answer guys, been off the net for awhile.

CEH - No wake on mouse or keypress in this BIOS

JON - I triple check, there is absolutely nothing there about restart on powerloss or anything in that art.

I'm Becoming stumped here.

E-machine had an issue with this same problem for several years (ghost booting). It was (is?) fairly common (don't know if they fixed it or not). Support people tried every trick in the world - both hardware and software to stop it...and finally most gave up and refered them back to e-machine. E-machine, of course denied having any such problem. It was discovered that some modems - oddly enough - could cause this phenomenom. Don't get me to lying as to why.

Did anyone ever solve this problem? I've got the same issue (started when I upgraded to Win XP) - and incidentally, I know 2 other people with the same problem.

The computer can be fully shut down, but if power goes out then comes back, the computer turns itself on. (Power change can be because of a power outtage, or just unplugging the computer and plugging it back in, or turning off and on the power strip to which it's connected).

Obviously, it's a real pain to have your computer coming on at random times, so if anyone's solved this, I'd appreciate some help!

Maybe you could change your power supply and see what happens. or try switching your computer to another outlet. or from the power strip to an outlet(if you use a power strip).


Please mention your opinions and or errors in my solution

Thank you

How about pulling the power on cable off the M/B and try it by pulling and reinserting main power cable. Will help identify where it is coming from.

Any advice I give is my best judgement based on my interpretation of the facts you supply. Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

You say it's a no name motherboard, but somebody had to make it. Try using Belarc Advisor or Sisoft's Sandra to indentify the board. If you can find out who made it, it's possible there is a bios update to solve the problem, Or you might find the manual on the web. Or if you can read the chipset numbers and manufacturer (ie. Via). An update to the chipset drivers might help.

It's gotta be hidden in the bios. The bios has the setting on, but the oem dummied down the display so you can't get to the page to see it. Like Dell or Compaq, the bios can do alot more than what you can see when you look. If you upgrade the bios you probably would be able to see the advanced settings.

Jontmke - I'll see if I can find a bios upgrade... the computer WAS originally a DELL and I think the motherboard/bios is about the only thing original left, so that's a good thought. I'll post again after I try it to let everyone know if it worked or not.

pctechnitian - I just moved and the PC does it both here and the old apartment, so it can't be a thing with the outlet. A new power supply's next on the upgrade list, but unfortunately have to wait for the cash to come in for it first! I'm kind of skeptical about that solving it, though, just because it only started doing this when I upgraded my OS... so (if my thinking is right) if it was a straight hardware thing like the power supply it would have done it with the old OS, too.

Thanks everyone

After reading through these posts, I am left wondering if the computer is actually off when shutdown? I noticed that the OS being used is not mentioned, so I am wondering if it isn't a later Windows version with the hard to fix shutdown problems that seem to crop up in Windows 98, Windows 2000 or Windows XP. The system appears to shutdown, but if you look closely, there is still a blinking cursor in the upper left corner of the monitor and the system gives all appearances that it is actually off, but the hard drive is still spinning. When the power outage occurs, that could be enough to incur a warm boot and restart the system.

Just something else to look into.

Fluxvoovoo is on the right track I think. Some modems have a power up on ring setting. It will start your computer if your phone rings. A power back on situation could cause a slight surge and the modem may see it as the line ringing and turn the pc power on. My sons computer would "ghost start" whenever the phone rang until I informed him of this feature. Good Luck
