power consumption: acpi vs apm ---> apm is the winner by far for suspend mode
On suspend mode, both of my laptops (IBM T40p and T42) have very
low performances using acpi. A fully charged laptop usually doesn't last more than 15 hours in standby mode!
However when I switch to apm, both laptops last for a few days!
Not sure if it's a hardware issue or software.
I have always experimented these issues (kernel-2.6.18, 2.6.19 2.6.22 and even 2.6.26).
Please let me know your experiences.
