Hi @nenees ,
Does it turn on with the charger connected and switched on?
If not try the following:
Switch off and disconnect the charger from the laptop (if connected) and then remove the battery from the laptop.
(Here’s a link to the [http://h10032.www1.hp.com/ctg/Manual/c01951704|service manual] scroll to p.47 to view the procedure to remove the battery)
''Press and hold'' the laptop’s Power On button for 30 seconds to drain any residual power from the laptop.
Connect and switch on the charger to the laptop. (leave the battery out at this stage)
Turn on the laptop.
If it starts, allow it to boot all the way to the Windows desktop. Once there allow the HDD activity to settle and then shutdown the laptop in the normal manner.
Once it has completely shutdown, switch off and disconnect the charger from the laptop.
Reinsert the battery into the laptop.
Reconnect and switch on the charger to the laptop
Turn on the laptop.
If it starts, allow it to boot all the way to the Windows desktop. Once there allow the HDD activity to settle and then check the battery charge status.
If it is charging allow it to fully charge before switching off and disconnecting the charger.
