Having problems with your HP Compaq 6720s Laptop ?

Hp compaq 6720s wont turn on got new charger but still wont turn on


Answers :

I have just had one of these laptops in for repair and have looked all over the net for a possible solution without success, i tried the bios reset, checked the psu, replaced the memory, and tried the power off battery out trick all without any results.
then i decided to dismantle the laptop to see if there was any visable problems on the mainboard (loose connections, unplugged cables, poor solder etc.)
after taking it apart and cleaning all the dust from the fan i test powered it back up to see and low and behold it started fine, thinking it was magically fixed i rebuilt it and powered it on again but now the same problem was back (seems to power on, orange light by the power jack flashes about 5 times then nothing)
took it apart again, removed all attached components and tested again, powered on fine again, means it must be one of the attached components, after testing each part one at a time i found that it would boot fine if i left the dvd drive out and would shut down if i plugged it back in, so after this long post the answer if all the other options dont work is to try removing the dvd drive and try it that way.
The power board should have a problem SO take it for cheek-up at the nearest PC technician near you. Cheers
