Another ZV5000 issue

Archived from groups: comp.sys.hp.hardware (More info?)

My pavillion zv5000 laptop (about 6 months old)
indicated low battery even though it was plugged into the wall almost
constantly.
Today suddenly the laptop has no video signal.
With the wall power source attached the power button lights up blue but no
video signal. Plus the laptiop gets very hot.
If I unplug the wall power the blue light still stays on.
If I pull the battery out then the blue light goes off.

So my possibilities are;
1. Battery needs to be replaced
2. wall power connector bad (although this laptop
was hardly ever used on battery alone).
3. Motherboard or some other internal part is shot.

Any opinions on which?
Thanks very much
