Let me see if H ave this right.

With the charger plugged into the lap top, but NOT connected to
the mains, the laptop functions properly.

If you plug the power supply into the mains, the laptop goes
stupid and hangs up.

IF that's the case, I would suspect that something is wrong with
the charging supply. Such as the voltage is way high, causing the
laptop top get annoyed and hang up.

Have you measured the charger output with no load on it? (I.e.
not plugged into the laptop.)
