While I agree that your inverter may be bad, I noted that it works fine on your friends machine. Run the current checks with it as the load. It is entirely possible that your brick is to blame. The bricks have built in limiting circuitry for overvoltage and noise rejection. If your brick was exposed to a big surge, this circuitry can be damaged (lightening is a common cause) although the brick may still work fine on good AC power. Your inverter may have just enough ripple that is being passed through to your computer (Not Good!). If your friend's machine works fine and has similar or higher power requirements, then I would bet against the brick and not the inverter. Test you computer on another brick if you can find one (not easy on old portables, I know).
P.S> A "Good" surge suppressor strip plugged in between your brick and the inverter might also help verify this cause.
