low battery life


im running slackware 10.0 with APM kernel on an ibm thinkpad laptop. in windows it has about 2,5 hours battery life. under linux its only 50-60 minutes.

any ideas why the battery lasts so much shorter in linux?

Hard to say ... I don't know which make and model you're
using, and how well it is supported in Linux. I don't know
whether you would be better off with acpi.

My TP R32 lasts for around 2 hours in Linux, and I can't
bear windows for that long ;) ...

One thing that may have an effect is that the machine
runs on 1.2 rather than 1.8 when on battery. I use ACPI,
btw, with apm I had weird things like repeating keys,
clock going wrong (fast, slow, randomly) ...


Cheers,
Tink
