Computer starts by itself! Help please.

Ok, I have a Dell Laptop running WinXP and when I seem to shut it off for a few days, it will automatically turn itself on after a few. Does this sound completely bizarre, or does someone know if there is a setting I need to disable?

Do you have updated virus protection on it? Is it hooked up to a network or the internet when it does it?

You can set your computer to boot on network activity, but I would assume that would happen more frequently than "a few days."

If you have a soft power button, it could be a disruption in power to the machine. For example, you could unplug it, plug it back in, and that may trigger a reboot.

That's the thing. I had been leaving this computer plugged into the network when I would leave town on business and invariably when I returned it would be on.

So the first time it happened I assumed I'd never shut the computer but rather had some sort of a mental slip. But then it happened 3 more times. Anyway, so for the past 4 days this computer was sitting unplugged from the network (though plugged into its powersource) and then last night, it was on again. Kind of frustrating.

As for virus protection, yeah, I'm on top of it. Found a couple worms the other day, but cleaned them right up.

I think das in on the right track. In the BIOS under power management there may be an entry called Status After Power Failure with choices like Off, On, Last State which might be set to On. Have a look.

The Dell BIOS also has a feature to turn the system on automatically at a pre-set time. I have my home system to automatically boot in the evening. Check it out.

Some kind of Wake-on-LAN setting?

Very possible, especially since he said "plugged into the network."

On the other hand, if he found worms on his machine the other day, that tells me he is engaging in risky behavior of some sort to begin with. No AV software gets 'em all.

I don't see how a virus could turn a computer ON unless it was somehow in the BIOS, and it can't get into the BIOS unless it's flashed onto the chip.

Yeah, no. I check daily before I run any 'risky' files. I found a few flagged and deleted them. I know I'm clean now.

Let me point out that when I am not connected to the network this issue is arising.

A virus could easily change CMOS settings, it doesn't need to flash the chip. Although software running under Windows is a fairly standard way of flashing the BIOS. I do it all the time.

And manufacturers often provide BIOS setting routines that are accessible from the control panel. Those programs change the CMOS settings.

Ok, going into the BIOS was smart. Stunning that I didn't think of it.

Wakeup on LAN is disabled

But Auto-On Mode was set to daily on at 00:00. The odd thing is, this has only happened recently and I've had this particular PC for half a year. Anyway, I disabled it now, and we'll see.

Thanks much, guys.

Oh, and worm aside if the problem was a changed setting it may have been my own stupidity. I like to dig in and play around with settings. Though I don't think this is one I'd have screwed with purposely.

I didn't even look at the top of the thread to see who we were talking about. Hell, I know you engage in risky behavior. You should probably wear a body condom when you surf.
