Hi I have a hp G70 that is baffling me - on boot up the hard drive kicks in for a few seconds the CPU fan is running at a normal speed, the backlight of the screen is lit but is just black, I can't find any way to diagnose what the issue is and what is wrong with it, my first thought was the harddrive but with it not even showing the bios that makes me think otherwise, I have tried to connect it to an external monitor but it seems to have no output at all.
Has anyone got any ideas please cause I'm stuck on this one
I took it completley to pieces and visually checked the internals. I found a bare wire on the wifi ariel lead 2 which threaded just next to the fan on the internal casing. other than that all was fine other than very dusty cleaned and cable was insulated.
Replaced the dvd drive - no joy
Replaced the RAM - no joy
Took battery out - no joy
tried external monitor - no output
Ran hard reset - no joy
Tried running bootable discs - no joy
Ran usb bootable - no joy
All in all no joy - ran out of options.
I researched more on net with no joy - HP Website (seems to be a common problem) but found that HP motherboards do not cope very well at alll with hibernation and can fail, and do constantly fail. The story goes that HP extended the warranty of the motherboards by a year due to so many issues but checked the serial on the site and its 16 months over warranty.
If anyone can shed any light on this and point out something I have missed then please let me know
What graphics card does the machine have? HP extended the warranty of many machines because of the soldering fissure issue present in graphics card surface-mount chips. You can heat up the GPU with a heat gun and it will remelt the solder and probably get the machine working again, but it's a temporary fix; the cracks will happen again. You can get a new board, though.
