Laptop won't boot

[hdgr]

I have a laptop that will power up, but then just show a black screen and no other signs of activity (apart from illuminated power indicators).

I have tried turning it on without the battery and it starts up to the windows start-up screen then freezes. By using just the battery it works absolutely fine, but when I try to reconnect the power lead, the machine freezes.

I can't just use the battery, because it is worn out and NEEDS power to work.

Can anyone help??

Looks like a faulty charger to me. Try another one if possible. What make and model laptop is it ?
