HP Probook 4510s power connection blinks 8 times but won't boot

Hi There,

Maybe I'm repeating other posts but couldn't find one that was close to this. Problem is, while working on a program on my HP Probook 4510s it suddenly shut down and now power connection blinks 8 times but won't boot.

Do I need a new battery? Or is there another problem.

Owned the laptop for about 3 months.

same behaviour

 

where could i find a guide to troubleshoot this ?

 

LED blinking 8 times with battery …

 

LED doesn't blink without battery …

 

is it a AC adapter issue ?

take of battery, peripherials and adapter. Press and keep 20 seconds on power on button then plug in the power adapter WITHOUT the battery on....

Bad battery or power plung-in broken (poor contact)!
