Laptop dies when unplugged

I was on the road and had my laptop plugged directly in the wall without a surge protector. A storm hit, the lights flickered and my laptop made a popping sound (scary).

"Most likely the battery is shot. Perhaps that popping sound was one (or more) of its cells rupturing?

I say this because, if it was the motherboard (or some other component) that got fried then it probably wouldn't work when plugged in either.

What happens to the power light when you remove the battery but keep it plugged in?"

The T61 has a power manager program that can tell you the health of your battery itself. Try running that to see what condition your battery is in.

My guess would be a problem with the battery Control circuitry. It may be as simple as a blown fuse, or as bad as the whole circuit being fried.
