Yes 1-2sec then turns off. Battery will charge if I keep doing it many manyJust to clarify, do you mean each time you plug in the ac adapter, laptop charging LED will light up 1-2 secs then turns OFF? Does it ever charge the battery (even if LED is off)? Are you using original/genuine HP AC adapter? Have you tried another battery (for testing)?
I did exactly what you say a week ago , and I got a new ac power supply (the old one was doing the same thing). Ok, I guess the a new Battery is next . ThanksIts the female jack in the motherboard, I have one of those same laptops and they are known for it, you can buy a new one off ebay for around 6 bucks, but its a little time consuming getting to the position on the motherboard so you can solder the new one on.
