1 long beep following by 2 short beeps, video card problem. The Dv2000 sadly is a recalled, defective model, lets just say HP fucked up. This short tutorial will allow you to bring your laptop back from the dead, without opening your laptop. I read this on forums and gave it a shot. IT WORKED!
Reflow technigue:
1.Turn on your laptop with the adapter plugged in.
2.Suffocate/ block the vents, the objective is to heat up the laptop. I use pillows.
3.Wait about 25-40 minutes, till you hear the fan at its loudest.
4.Hold the power off, turn it back on.
5.Comes right back to life.
Sadly, this will only TEMPORALLY remedy the problem, its a good technique for a back-up.
GOOD LUCK!
