Hi

On my Sony Vaio laptop (PCG-C1VRX/K picturebook) I use kernel 2.6.11. I
am on Debian Sarge. When I suspend, the laptop suspends just fine,
unloads everything it can, what it cannot, I included in the script to
force to unload, and it sleeps very fine when I close the lid. First
issue, it wont wake up when I open the lid, only when I press a button.
Second issue is that it wont come back to live even after button
pressed, except if I give a boot pharameter to GRUB as follows

acpi_sleep=s3_bios

Now my Grub entry looks like this:

title           Debian GNU/Linux, kernel 2.6.11 
root            (hd0,1)
kernel          /boot/vmlinuz-2.6.11 root=/dev/hda2 ro
acpi_sleep=s3_bios initrd          /boot/initrd.img-2.6.11
savedefault
boot

When I use this option, it does wake up when I hit a key. However, while
asleep, the screen isnt completely off. I can hear a buzzing sound,
very soflty, but I can definetally hear it. Also, when I open the
lid, (it wont wake up yet, only on button press) I can see some text on
the screen if I tilt it in the right angle. THe LCD seems off, but it
does has some text on it, so it cannot be off, just dimmed to a maximum.
ANd the buzzing sound gives it also away. I left the machine suspended
at 33% battery yesterday at 2AM, and by 7AM when I woke up, the battery
was dead, and the laptop shut down. Usually 33% gives me 40 mintues of
work time, I think it should have lasted for a 5 hours suspension, no?

Thanks for any help

Benedek
