I am experimenting repairing a dead thinkpad x20. The machines power light
flicks momentarily when the dc jack is inserted or removed.

Did you rule out an AC adaptor fault? Measuring its voltage off load is no
use.

I accidentally shorted a couple of pins on this IC, and now the behaviour
is much different, with lights doing funny things.

There may be more extensive damage now. If the screen is good I'd look on
eBay for a working X20 with a cracked screen.
