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 |
okay thx, ill try out acpi later.
btw, how do i suspend/sleep the box with acpi? and how do i set the cpu to go down when on battery life? |
