Issue with wake from suspend state via USB device


Hi LQ,

I have an USB keyboard attached to a laptop, and I can suspend the laptop via the sleep button on the keyboard.

However, I can't wake the computer again by using either the connected USB mouse or the keyboard. How do I fix this?

I am running Ubuntu Netbook Version 10.04.
I hope you can help.

Nor the Wake on Lan option.

Couple of thoughts.

What command is that key press executing?
Is it
Code:
acpiconf -s3

How are you awakening it then? Or are you shutting it off with the power button?
My point is, are you sure it's sleeping and not powering off or hibernating with that key press?

Usually a brief touch of the power button on a sleeping machine will wake it.
Are you sure that the machine is not awakening and it's just the display that you are loosing? There's been problems with nvidea in resuming.

Other than that check the BIOS, try a PS2 device, the power button should wake it.

You don't want wake on lan normally.

I agree that the last ditch or correct way may be power button.

There may be some acpi settings in bios. Look for any and report.

Yes, I am sure that it is in S3 state. The power light blinks as if it is, and I can wake it using the power button directly on the computer - but not with the keyboard.
When I press any button on the keyboard, nothing happens. If the computer woke without the screen, the HDD and WiFi lights would turn on, as they do when I wake it with the power button. They do not, however.
