Whilst it's possible for the laptop and PSU to
communicate, I doubt that was the problem.

It's more likely that the PSU was unable to supply
sufficient current - and therefore the voltage
drooped - or the supply voltage was simply out of
the laptop's tolerance.

If you can find a third-party PSU with the right
connector, sufficient current, and tight enough
voltage regulation, then I'd expect it to work.
The tricky bit may be finding a spec for that last
condition.
