Hi i have other kind of problem; when i suspend the computer (win xp or 7) at few minutes (never the same time) it on again alone. I have already disabled the lan port (well all the online connections had been disabled) and i dont use none of configuration about automatic suspend or sleep or hibernate. I believe the source is the BIOS (like this issue about ACPI). here is my configuration of ACPI settings of the BIOS for now: -Suspend to ram: auto -check ready bit: auto -away mode support: disabled -restore on AC/power loss: power off -ring-in power on: disabled -pci devices power on: disabled -ps/2 keyboard power on: disabled -rtc alarm power on: disabled -ACPI HPET Table: enabled I just want my computer can enter in suspend mode until i awake it again by me, not automatic (well a advice to reduce energy while the computer is on would be nice). Thanks
