X crashes on batteries
Hi All,
I have a DELL Inspiron 8100 running RH 7.3. The system/installation is very stable when running plugged in, but when the power cord is pulled out, or if I try to start X when running on batteries it goes to blank screen and I have to restart X. I think it has to do with the laptop package installed on the box... I use KDE 3. Any insight would be greatly appreciated. Thanks, Matt |
First guess is a power management problem. Are you running apmd or apcid? How is your BIOS setup to handle power-saving?

mcleodnine,
Thanks for your response. I am running apmd with the following options: -p 10 -w 5 -W -P /etc/sysconfig/apm-scripts/apmscript The BIOS power settings are just as they are when the computer was shipped, here are the details: ------------------------------------------------------- Power Mgmt: Enabled Display TIme-Out: Batt: Enabled, AC: Disabled Disk Time-Out: Batt: 3 Mins, AC: Disabled Suspend Time-Out: Batt: 10 Mins, AC: Disabled S2D Time-Out: Batt: 8 Hours, AC: Disabled Smart CPU Mode: Batt:Enabled, AC: Enabled Display Close: Batt: Suspend, AC: Active Alarm Resume: Enabled Wakeup on LAN: Disabled Intel SpeedStep: Enabled CPU on AC: Max Performance CPU on Battery: Battery Optimized Auto On Mode: Disabled Auto On Time: 00:00 ------------------------------------------------------- That's pretty much all I have.. |
I have a similar problem.
Travelmate 350TM RHat 8. + Linus Kernel 2.4.18 + KDE 3.1 Freezes randomly. (no mouse, no keyboard, no network). Will try ACPI & APM off and 2.4.20 Freezes with or without power plugged. |
sometimes apm is evil even windows systems can become unstable from it.
might i suggest looking at readhats site to see if its a global issue also try killing the apmd deamon and unplugging power and see if it becomes unstable while not not running apm at all this will help test for the possibility that the systems apm could be incompatable with the linux apm commands . could also be a bios issue from factory . maybe the latest bios is in order hope this helps to give you some leads |
just to clarify, since I run on a laptop too.
If you use ACPI you shouldn't use APM? I thought they were two different things? |
Hi all,
I have RH8 Kernel 2.4.20, APIC installed and have the same problem than Pablo. My laptop freeze when battery gets uncharged, or if I have the charger plugged and I unplug it |
Beware it is not the same thing APIC and ACPI.
I compiled a kernel without APM or ACPI at all. Since then, I've got no hangs BUT my 2hours battery only lives for 20 minutes. I'll wait for another hang (if it comes), and will test some other things. |
