Windows Desktop Search 3.01 Is Draining The Juice

This morning, my D400 died on me after 45 minutes, it is highly unusual since it was not hooked to the BB unit (that little thing sucks - not leech - the juice).

Back in the office, I:

1. started intelppm service - but it didn't help much.
2. un-installed WDS 3.01 - which helped a lot.
