XP laptop - 3 beeps on boot - nothing on screen - help!

hiya all....HELP!

i have a hp pavillion dv6000 laptop, i left it on this morning when i went to work, and when returning some 7ish hours later, i arrived to find my laptop what appeared to be in sleep mode...i moved the mouse/touched the keyboard to "wake" it... and the laptop appeared to come to life...but still a black screen.

I restarted by powering off, then on.. and upon startup i just get 3 beeps from the laptop speaker.

You can hear the cd drive checking for disk, and the hard disk "whurling", and the  3 beeps - the laptop remains "on" but nothing on the screen, not even the HP loading screen before xp starts

Ive tried removing batter for 20+ mins and battery is fully charged

Ive tried ringing the HP technical support but they are closed till monday :(

It was orriginally a media centre laptop, but its now got windows XP performance edition on it

Any help/suggestions would be greatly appreciated

Thanks in advance

Try press and hold power button for 5 minutes to cycle the power and try start system again. If still problem, reseat the memory on the back and try boot system with AC adapter plug in.

Post back when you can.

3 beeps on startup is the POST error message telling you that the graphics
adapter is not present (i.e. it has failed).  
Have you tried the VGA out on your laptop? If you still have a black screen it is most definitely the graphics adapter.

Can you describe the 3 beeps in more detail?  All short beeps?  All long beeps?  1 short than two long?  this can meen the difference between RAM and Video Card failure.  My guess is that one of these two components has failed.

A couple of things to try:

1)  If you have more than one memory card in your laptop (you'll have to pop off a small cover on the bottom of the unit) you can try removing one or the other and trying to boot the machine.  Also - swap their positions in the machine to try all possible configurations.  If you can narrow it down to only one of the chips than you know one went bad.  You can also try completely removing the chip to see if that makes the error code change or if you can get it to boot that way.

2) If you have an external monitor available try plugging it into the laptop and see if you can get any video out of it at that point.  Some video cards attempt to detect a display and if none are attached they can cause an error code.  

If both of those fail and the unit is still under warranty - you'll probably be sending it back to HP to have the motherboard replaced.

hiya

tried 5 min restart but cannot find reset for memory on back (havent looked inside because do not want to void warranty by opening it)

also it is definetly only 3 beeps, so looking on the website posted by sphinx32, i cannot see a match for any of the syptons/problem

Most manufacturers won't void the warranty if you simply open the memory door.  It's a common practice for people to add RAM to their notebook.  There is usually only one screw to loosen and the door will open revealing either no additional chips, one additional or possibly two additional chips.  Since you don't get any external video I would look at the RAM next.  If you're uncomfortable opening up any part of your computer I would leave it alone and wait until Monday to call HP and send it in to get it repaired.  It sounds to me like you have had a hardware failure.

Your other option is to take it somewhere and have a technician look at it.  This will probably cost you at least $50 and might not be worth it if you still have the warranty.

Best of luck - Matuse

If your laptop is still under warranty and you have a hardware failure (which you clearly do), you should return it for a repair or replacement.  In the UK it is a contravention of the Sale of Goods Act to refuse to repair or replace any new goods purchased within the last 12 months.  Where did you buy this laptop?

Go further with plugging in the external monitor...  

Try hitting the Fn + F8 key a few moments after plugging in the monitor to put the laptop into presentation mode.

proudler,

"...cannot find reset for memory on back (havent looked inside because do not want to void warranty by opening it)..."
If your laptop is still under warranty, I repeat, you should return it for a repair or replacement...
