Machine won't power on.

When my Hp dv6700 didn't turn on I put in a Ubuntu boot disk and it worked. So I switched operating systems (from Windows) and now my laptop works again. Granted I lost all my data on the hard drive, but at least I had a computer that works.

Your problem could be a bad motherboard or CPU.

Are you asking about HP Pavilion dv6000 notebook?

1. Could be memory failure. Try removing memory one by one.

2. If it's not bad memory, most likely this is known GPU failure.

You can try fixing (temporarily) the GPU problem using this trick:

How to fix video problem on HP laptops

Old question and not sure if it is even still an issue for the original poster. I just researched the dv6000 and was amazed in how many people have issues with it. The problem is is the motherboard, and the symptoms include loss of bootup, VERY slow bootup, WiFi stops working, etc. is simply that the MOBO board overheats and fries the video driver chip. The cooling design of this PC is inadequate. Short of replacing the motherboard I do not believe that there is much that you can do. I posted instructions how to reflow the board here will not power on Even if you get a new MOBO you might have the problems agai for as long as it has the NVidia chip. It is my understanding that there are now revised board out that have the ATI chip and do not have those issues. Good Luck

I had the same problem.. when i try to power it up, just lights come for 1 sec and then turn off again. Strange but i removed the wi-fi card and turned on the laptop and now it works just fine. Then put back the wi-fi card and still working fine.
