I am experimenting repairing a dead thinkpad x20. The machines power light
flicks momentarily when the dc jack is inserted or removed.
I accidentally shorted a couple of pins on this IC, and now the behaviour is
much different, with lights doing funny things.

Anyhoo, the machine was dead to begin with..

I wonder if somebody could please tell me what this IC does, and how I might
find a replacement to try out?

Here's a pictu
