Youre right - the laptop details will help:
IBM T43p
I will look into bios updates too though they are going to be tricky
as it seems i need a non-usb floppy or windows xp (neither of which I
have)
The laptop doesn't go to sleep - I use the kde powermanagement tool to
set the sleep when the lid is closed, but in the newer kernels it just
doesnt work - all the sleep options are greyed out and I can't figure
out why.
I have looked through various logs but have been unable to find pretty
much anything acpi/sleep related at all.
Maybe the problem is not the kernel... i suppose it could be that kde
doesnt like something in the newer kernels.
