I have a HP Pavilion Dv5z-1000 that when I turn it on the screen stay black as in doesn't come on and Number lock light and the Cap Lock light come on and off at about 1 or 2 second intervals. Any one have an idea as to what is happening?
Could you please tell the sequence of flashes? Could be a defect CPU, GPU, BIOS corruption etc. There should be a certain number of flashes, then a break, followed by a certain number of flashes etc. Could you please tell the sequence? Check out the HP support forums; You'll find more posts from people with simular issues. Loads of complaints about the DV-series black screens, not booting or running 20/35 degrees hotter than chips specs. Try this: - Remove battery and charger. - Hold down power button for 30 secs. - Replace charger only and see if it powers on...
