Power schemes won't save

[mdarnton]

I'm trying to save a power scheme, and when I name it and click the "save power scheme" button it doesn't--the window clears, but the new power scheme isn't on the list. I've tried working from the battery icon on the tool bar, and via access IBM, but neither works.

I recently reloaded windows, updated to XP2, and updated all drivers to current, so there are lots of places this could be, I guess. Before I did this, I had put in several additional power schemes, no problem.

The computer's a 2378DHU T41.

Ideas, anyone? And, thanks in advance.
