What do you mean by 'your ACPI system'? Some sort of BIOS setting?Thanks for the reply! Cassiano
I didn't have ACPI on in my BIOS. After activating it, dmesg shows ACPI supporting S0, S1, S2, S4, S5 and S6, but not S3. Is this a hardware/BIOS limitation, or can it be overcome in software?
One more thing... When I am not using ACPI, everything seems to work fine. When I start using it, the keyboard and touchpad become less responsive.
Basically, it just ignores some typed keys and touchpad movements/clicks. It is really annoying to have to go through the keys one by one, in slow motion, and verifying if there was a response to each one of them.
Right now, I have ACPI off and have to suspend the PC via command line. With ACPI, I had the power button set up to do this.
Thanks for any insights! Cassiano Leal
