My computer is “waking up” all by itself, with no jiggle of the mouse. I set the times to short increments so I could watch it go to screen saver, then go to “sleep.” Then it just “wakes up.”
The weird thing is, this happened on another machine, too. We thought maybe it was the mouse being vibrated by the CPU, which is on the desk. We tested this out by moving the (wireless) mouse to another room. It still “woke up.”
We just bought a new CPU, and it’s doing the same thing! Boggles the mind, it does.
Please always provide machine and OS info! It is impossible to provide significant help without this.
I would start with networking: Are any network using programs running in the background? This can include anti-virus programs and many, many others which might periodically auto-update. It can also be a symptom of “wake on lan” when an outside network connection wakes up the machine.
There’s a BIOS setting for disabling stand-by interrupts from USB port signals, which is usually the issue when the computer will only hibernate intermittently. Some device will send a signal to let Windows know it’s still connected, and Windows will turn itself on in response.
