HP DV9000 Lights up, but no boot/no fan/blank screen

post #1 of 3
Thread Starter 
Hi guys I recently bought a power supply for a HP DV9000 a friend gave me. Not sure if it was working when he gave it to me because he had no power supply.

Anyway, I got the power supply and everything lights up, but! it does not actually start up. The only thing that happens in that the blue lights are lite. The dvd drive seems to work or make a noise, but the fan never makes any sound and you can see it not moving. I read that there is a major problem with the graphics card and there is a reflow fix. I just wanted to make sure this was the problem before I tryed the fix.

anyone have any info on what it might be? Most reflow problems I read about the fan at least started and the laptop beeped. this one does nothing but light up.

Thanks for any help

Hi, i had that problem with the gpu of my dv9000.
In my case all the leds lighted up, the screen had back light but remained black and the fans were spinning, i however never heard a single beep from the bios so i guess that maybe it's a failure that may occur showing different symptoms.

I can't be sure that your laptop has the same problem of mine (and like a lot of others) in the GPU's welds but if it is out of warranty i think you should try the process.
My dv9000 after 2-3 minutes of heating (i used a hot air gun at 300°C buyed for something about 20€) and 5 minutes of cooling just came back to life.
Hope that you can fix it, good luck!
