hp zv5000 weird power/battery issue

Hello,

I have a old hp zv5000 and it seems to randomly shut down, the problem is very peculiar. The battery on the hp cant hold charge for more than 10 minutes but the problem lies in the charger/laptop itself. The charger only seems to be able to charge the battery and the system only seems to runs on battery power, the battery runs out and the system shuts down (without any notice). When the battery is taken out of the system, it fails to start up.

I am not sure where the problem lies here, i am guessing somewhere in the mobo :S since the laptop itself cant turn on external power when the battery is disconnected and only seem to run off battery power.
Any thoughts are appreciated.
Thank you very much!

 

Anyone has any ideas? I was reading somewhere and it said something about internal circuit/voltage regulator. Any idea if its fixable or just too pricey..

 

The zv5000 series is notorious for having fragile power jacks. Resoldering them to the motherboard will usually fix things. Alternatively, if you can find a xc1000 media cable that will add an auxiliary power jack that you can use instead.
