HP DV4000 laptop turns on and off without loading

I was given an HP DV4000 laptop and it will turn on for 5 - 10 seconds (with and without the power cord) and then it turns off. The fan does kick on during this time, but the screen remains blank. Looking around online it sems it may be a battery or mother board issue...any suggestions?

My HP Pavilion dv4 is not booting.When I press power button all light blinks for a second and shut down.


1- try turning your laptop on with another Adaptor.
maybe your adaptor cannot supply enough electricity for your laptop.
2- electrification center of your laptop is damaged.

Computer will not power on. Lights up for second


Take out the battery and only hook up the AC Adapter. Then turn on the laptop.

If it doesn't stay on then take out the hard drive and the dvd drive.

If it still doesn't stay on then the motherboard is bad and would need to be replaced.

thanks for using fixya!

Perhaps, I suggest that you bring your laptop you a service center to check if the board has been shocked or short circuit. Please remove the battery pack for now.

Good luck!
