So far I am able to suspend it using "echo 3 > /proc/acpi/sleep", but closing/opening the LID or pressing the Fn button turns the power LED on (but it doesn't disable the "moon" LED indicating sleep) and nothing more (hard disk doesn't seem to spin up - i.e. I can't hear it) - the screen is completely blank and it doesn't respond to any keyboard input. I have to reboot using 5-sec press of Power button. To suspend the laptop I have to manually remove CD-ROM drive from the bay (laptop powered off of course during the operation). With CD-ROM plugged in it displays "hdc: drive not ready for command", "hdc: DMA disabled", some more error codes and hangs indefinetely. I have tried 2.6.5-rc2-mm4 and 2.6.5-rc2-aa4 - both exhibit the same behavior. I booted clean in single user mode (no hotplug running, no X, no AGP modules, no USB modules). As a side note - the USB mouse I'm using was connected to the computer all the time during experiments and even when the laptop was suspended the mouse was powered on. I have no idea if this is an expected behavior (haven't checked under Windows XP though). How can I debug this issue? Is ACPI S3 of any use under 2.6? Please Cc me all the answers as I am not subscribed to acpi-devel.
