I definitely am impressed with the solution hp pavilion dv9720us xp LEDs work, normal noises, but no hd activity. The “pull the plug and hp pavilion dv9720us xp and hold power” trick mentioned here is not working. Bad connection between the video cable and motherboard. Take a closer look at the button on the hp pavilion dv9720us xp bezel. This also worked on a Dell Inspiron – bonkers!

Laptop is dead. How to troubleshoot.

Jose, Take a closer look at the power jack. I think and hope it might be the battery but I dont have a way of testing it and I was thinking if its ok to just plug the laptop to the outlet with out the battery… would that be ok or do i have to have the battery in the laptop to convert the power so it can use it….

Thanks so much Julie. I unplugged it, took the battery out then held the power button down for a minute. CPU failures are hp pavilion dv9720us xp common. Hp pavilion dv9720us xp do not know what it could be.
