Hp pavillion beeping and will not boot up

My HP started beeping lasting night and it had shutdown but the power button was still lit up. It beeps 1 beep every 2-3 seconds and nothing. I held the power button down and forced a power off the waited a while and turned it back on and the same thing still. The light on the CD lights up and the 3.5 floppy lights up but that is all, no fan noises, no hard drive sounds. Can anyone help me?

You might try looking at the memory slots -- if there's more than one memory stick remove each in turn, restarting each time and see if it come to life. Buy a new memory stick.

"I popped the battery of the motherboard and tested it, it tested fine, but when I put it back in, the pc booted up on its own without pushing the power button....."

Best not to insert stuff into the motherboard with the wall power connected.

Did you try the BIOS jumper -- shorting that is more effective at clearing a fouled BIOS than just removing the battery for less than a minute. Because there's a capacitor backup (just so you can change the battery without losing settings)..

BTW I am very limited in my PC repair knowledge. I would not even know how to find the bios to jump it.

This sounds like a motherboard error. When it beeped, how many beeps were there? Was it a constant beeping or a set of three or five beeps? Different beeps in different sequences represent error codes, and allow you to work out what is wrong with the hardware.

Hi Traci,

What is the model of your HP laptop?

If it's DV9000, DV6000 or DV2000 please have a look at this very useful video which i came across awhile ago, it helped me fix my hp laptop which was having blank display issue.
