Battery Power Meter Discrepancy

Archived from groups: comp.sys.laptops (More info?)

I have two battery power meters on my sony pcg-sr17k. The sony
provided power utility appears to do a more thorough job of predicting
remaining battery time. It says 2 hours right now whereas the windows
power meter says 30 mins. I'd like to disable the windows power meter
from showing up in the taskbar. I have no desire to have two meters
sitting beside each other.
any clue how to make the windows power meter never show up?
