Description Kasper Dupont 2005-01-01 12:41:46 UTC
Description of problem:
When switching from external power to battery power the KDE session is

Version-Release number of selected component (if applicable):

How reproducible:
Happens most of the time when external power is removed

Steps to Reproduce:
1. Run KDE on a Presario 2166EA (or similar?)
2. Charge the battery completely
3. Remove external power source
Actual results:
KDE session is terminated

Expected results:
Battery applet is updated, nothing else happens.

Additional info:
kdeutils-3.2.2/klaptopdaemon/portable.cpp already has code around line
490 to ignore the first few readings after switching to battery power.
It may as well be extended to ignore any reading of zero, which is
obviously wrong.

Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.

Avoid problem by ignoring rate 0 readings

Here is a patch which seems to solve the problem on my system. I have been
using the patch for a month, and haven't seen any problems since.

I haven't seen this problem on FC4 or FC5. I will close the bug.
