I installed E DR17 yesterday (with the help of Prof K's RPMS and
advice) and was troubled that it was using 40-80% of the system CPU,
even if the PC was sitting idle.  I started searching posts in this
list and saw Raster's blog, which (2 years ago) showed that E with no
modules was very fast and light.  But on my system, it was bloated and
sometimes slow.

What the hell?

I removed modules one by one until the CPU usage dropped into the
normal (less than 5% range) and, guess what (drum roll please):

The battery module was the culprit!

In this Dell D820 laptop, I have 2 batteries.  One is the usual, one
is in the so-called "external bay" and it can be swapped for a CDROM.
I should have realized E was having trouble with this because the
battery monitor reported nutty values like 143% and it constantly told
me my battery was almost out of power.  Removing the battery module
solves the CPU problem. What a relief.

I realized I can run "gnome-panel" or the KDE kicker on one side, and
the E shelf on the other, and can use the battery monitor from those
other programs.

I did remove the second battery and try the battery module again, but
it still showed high CPU usage.  So I don't know for sure what to
conclude.  Perhaps the whole framework of the motherboard & chassis
has it confused?

If any developers want more information to investigate this, or you
want me to file a formal bug report (in case this is not known
already) I will do.
