Your post's title (but not content) advises you are having to remove the battery.
Have you tried another battery?
If not the battery, this sounds like a problem with the charger, which I think is contained in the power lead.
When first switched on, it overloads and trips out.
Pulling the (power) plug, fully disconnects and it resets.
Have you tried:-
a) supplying power to the charger, with the Acer switched off for 15 - 20 minutes, then switching the Acer on.
This allows the charger to warm up, such that it then might not trip out when loaded.
b) another charger
Good Luck - Keep us posted.
