Please help, when booting the power, light, fun on. The caps lock and num lock lights are blinking. Cd drive sounds like reading the cd when putting the recovery cd. But screen is black.

Welcome to the HP Forums,

We'll be with you until it's all sorted & beyond!


What is the sequence of the lights blinking on the caps lock and the num lock key?

While you respond to that, here's what you need to know and do:


There are many reasons that a computer does not startup or boot into the Windows operating system. If your computer will not start or boot, you will see or hear symptoms to indicate the general area of the problem. If you are not sure what the problem is, see Overview of How to Troubleshoot Problems When a Computer Does Not Start Up or Boot Properly.


Startup Symptom: LEDs glow, but the computer fails to startup or boot and displays a black screen

  • Use this document if the LEDs glow to indicate that power is available and the sound of a fan or spinning hard drive can be heard, but no colors, images, or text are displayed on the LCD display.
  • Do not use this document if there are no sounds from the computer when the power is turned on. You should check for a different problem; such as a loose RAM memory chip or disconnected hard drive.

The cause of this problem may be the failure of a hardware component or an error in the instruction being sent from the BIOS to a hardware component.
