    Can you remove the graphics card out of the hp pavilion and put another one into it?

  • Anonymous Jan 06, 2009

    I had the same problem. Actually one day the laptop froze-up and the only way I could get it to respond to ANYTHING was to disconnect the AC supply and remove the battery. But then when I reattached the power and reinstalled the battery I had a dead computer..........no fan, no lights, nothing, absolutely dead.

    I let it sit for a few days and after doing some research on the internet, I decided I would dismantle it to see if I could find a problem. After removing almost everything, except the actual motherboard (I didn't find anything that looked visually wrong) I but everything back together.

    This time when I powered it up it started to boot up but then froze on a black screen after the windows logo came up (only about 10 seconds or so. I disconnected from all power again. Then tried boot it again. This is when I got the the "flashing blue lights after trying to start for only a second or two" repeating over and over. I was going to reinstall the CPU as suggested by someone here but I though I would tinker with the Ram modules first. I took the only stick of Ram I have in the computer and switched it from the socket it was in to the other socket. I hit the power button and.......voila it works now. Thanks Fixya.

The hard drive holder has enough slack so if the laptop is jostled, the hard drive pulls out of its contacts.
Remove the screws holding the hard drive in,pull out hard drive then push back in to ensure it is properly seated. this worked for me!.

Probably bad memory or loose CPU module. First try removing and resetting CPU. You'll need to remove Keyboard, Palmrest, and heatsink and shield beneath Keyboard. You'll need a small Phillips screwdriver to remove screws and small standard size screwdriver to loosen screw holding CPU. After removal/reset, put everything back together and try powering back on. If still same problem, replace memory located on bottom of LT located behind door. Also, you may have a memory module located under Keyboard next to CPU that may be bad.

HP Pavillion zd8000 won't power up


Try attaching a normal VGA desktop monitor to it. There should be a plug either on the sides or the back of the laptop. A blue one. That way you'll be sure.

Hi I have a hp laptop pavillion and the screen does not come on.


Good day sir, hi, your HP can either be of the ff.
  1. your lcd back light is bad, your lcd screen is dark, but you can see HD light blinking. This is happening when the laptop is loading windows. problem with the inverter circuit that provides power to the back light.
  2. Your back light is bad also can produce no visible screen.
The said problem can be repairable by simply replacing the said parts. but you need to dissassemble the laptop, Or get it repaired by your dealer. either of the two said solution you need cash. but check out first the warranty or estimates of repair. get the best deal.

HP Pavillion dv9700 won't power up


Try removing the battery and using only power cord to turn the laptop on. If that fails, try turning it on without power cord, just on battery.

If none of those work, then most probable cause of your problem is motherboard. Hopefuly you are either under manufacturer warranty or you have extended warranty with your vendor where you've purchased the laptop.

If your laptop turns on on power cord, but without battery, then battery is the problem. Also, if laptop turns on when it's only on battery but it doesn't when you plug ac cord in it, then the adapter is the problem.

Screen doesn't light up


Brand new? please take it back to your dealer. I assume you do have it plugged to the charger and it has power? it doesn't matter if the battery is empty or not, the laptop works with the charger with or without and battery.

seems like you got a faulty laptop.

My hp ze4300 will not turn on


Has there been a power surge meanwhile? If so, try unplugging the power cord, press the power button, reconnect power and try booting. Sometimes works.
