The light indicating it is charging comes on 1-2 sec and goes off, I can make it repeat the charge by unpluging the power supply and plugging it back in,
over and over again 1-2sec on and off.
any ideas? I changed the power supply and dc power jack.

Its 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.

Just 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)?
Yes 1-2sec then turns off. Battery will charge if I keep doing it many many
times, The adapter is not HP original , suppose to be compatible. Im going to
try a new battery next. thanks

It is NOT the "female jack". I just went through the trouble of changing mine after 2 days of reading posts on the topic. I figured I'd address the most common problem first. Unfortunately I'm getting the same behavior - the blinking lightning LED, and NO power at all when the battery is out but the adapter is in. I suspect it is deeper than the adapter, jack, possibly a component on the motherboard, I read in another post it may be the voltage regulator.
