My Computer Turns Off By Itsself?!

[Mikaila31]

I don't know what is wrong with it, it has been doing this for a while now. It is a Emachines computer and is located in a daycare. So when it first started happening I thought a kid kept pushing the power buttons since they blink. It never turns off when someones on it, only if it is on standy or is sleeping for a long period of time. Yet, a week ago it did it right infront of me, it was asleep one second then completely off the next. I swear it is possessed or something.

Does it turn off when it is not sleeping? (Meaning someone just closed the monitor without putting it to sleep) It could be that your settings tell the computer that if the computer is asleep, and no one uses it for "x" time then it turns itself off to conserve power.

What Operating System are you useing?

Just a theory....if it's on a powerboard with many other things it could be a powersurge cutting it off (drawing a longish bow)

Possible, but she said (assuming from the post) that it only turns off when it's in sleep mode. Isn't sleep mode supposed to conserve power, not surge the power. IMO i think it has something to do with her settings.

The machine is either going into Sleep or straight in Hibernation. E-machines are known for having power save settings, it will only do this when the machine is left unattended and not being used.

All computers have a cut of temp from what I know, I had to mount two extra fans to cool mine (old now )
as it kept cutting out.

Preciesly what I was thinking!

It has 3 modes, awake, standby,and sleep. Awake is when you are using it obviously, standby is where it goes to the screen saver. For sleep you push a button on the keyboard, the monitor turns off, and both the monitor and computer power buttons blink, if you move the mouse the computer wakes up and monitor turns back on. As far as I am aware it only turns off when in the sleep mode, and only the computer turns off completely, the monitor stays in sleep mode with it's power button blinking. The operation system is windows XP.

Yup definetly is your settings. To fix go:

Click: Start, Control Panal, Power options, and it should be there. If you can't see it straight away, trying clicking relevent things such as: "Change when the computer sleeps" and "Advanced Power Options".

Let us know if you've cracked this mystery

I had this problem in the early days of my computing interest, turned out to be the power supply unit (PSU) once I changed it to a larger wattage it worked fine with no inavertant shutdowns.
