Random Wake-Up

[Johnathan Lyman]

WindowStar, I can't remember if you answered this question or not because my head is pounding like none other, but what make/model is the computer in question?

Dell 755, Dell 745, Dell GX620, Gateway 4500. All are doing the same thing.

Do they wake up at the same time of day every time this happens?

Maybe check your scheduled tasks for the machine, possibly a scheduled defrag?

All random. Nothing scheduled, thanks for the ideas.

I really can't get past the network activity waking up the machines. But I think I'm officially out of ideas :S

SOLVED: Laptop wakes itself from sleep in Windows 7

No BIOS settings helped for me.
I found a forum elsewhere fingering the laptop lid.

Sure enough, when I closed the lid on my customer's immediately after telling the laptop to sleep and had the lid closed before it had finished going to sleep. It stayed asleep where it only stayed sleeping for a minute tops.

I went into power options control panel and selected "Change what happens when closing the lid".
I changed it from "sleep" to "Do nothing".
I kept the power switch at "sleep"

Then I kept it open and set it to sleep.
It stayed asleep like a well fed baby.

I closed the lid and opened it. It woke up.
Uh huh.

Put it to sleep again and left it overnight.
Still asleep in the morning.

Hope this helps some of you.

Looks like a defective lid closure switch is at fault. FWIW, this model has a lid without a clasp/hook/latch. This may result in touchier sensitivity. These switches may be more likely to think they are open that a latch that has actual physical, mechanical movement of a full half centimeter to engage and disengage.
