HP Pavillion dv6000 suddenly stopped working, won't boot, no HDD activity

you can also test the disk by hooking it to a working pc, and runnin some diags on it, or a scandisk for errors
does it show in the bios?

> followed by the fan coming on briefly, and then nothing

overheating? From the above, suspect the motherboard, but not familiar with the beep code I'd try swapping the rest, monitor & card and KB as well. HP has a problem with the circuit itself, but initially that shows itself first more often by rebooting once up.

> started doing something else, and when I came back a little while later, the screen was blank

That describes the mobo issue well enough

Look at the cable, I think I heard something about one of the pins being critical here. Try replacing disk cable and observe the contacts

Pheidus, thanks for your comments, but the HDD is just fine. The clicking isn't coming from the hard drive, it's actually the opt. drive looking for it disk it seems, but thanks for the comment. And I don't have any display, I have absolutely no activity from the laptop except the lights coming on, so BIOS is not an option, but like i said, the HDD is fine, as I bought an enclosure last night, and tested it, everything is intact(and now backed up).

Sunbow, thanks for the comments, It's a laptop, so I don't have a spare display & KB to swap with it, and I think you might be thinking I'm talking about a desktop, if you mean swapping out the video card...I wish I could swap out the video card, I would have upgraded a LONG time ago :) !!!! I was thinking that it was overheating, so I tried disassembling it and blowing it, but not much dust came out, and it isn't getting hot.

Oh, and the beeps seem to be coming from the DVD drive, and not the BIOS, so now help there :(

Thanks for commenting, I'll keep trying to figure it out, before I have to take it to a repair shop, and keep you posted.

> the video card,
(that means mobo, like for swapping bios)

> beeps seem to be coming from the DVD drive
Thought you swapped...

Need new one, huh? Too bad, not for HP but other laptops had history of HD lockup with many cures, one fav was to bang the corner of notebook, the drive would loosen and boot. Very popular. Culture hear introduced me to placing it in freezer. Different. Don't know a person who did it but the response in EE was acceptable.

Since we do not suspect S/W, may I suggest you use EE's H/W section TA if you end up needing to ask this again. I did not know dvd beeped, those would typically be from speaker

did you test it, as suggested?

Nobus, yes, I tested the drive, all is well there.

I'm thinking it may be the onboard graphics? I was reading somewhere that said if the vpu BIOS does not load, the system does not know where to send the video, hence an otherwise functional system becoming inoperable.

Another cause for concern I  have been thinking about it is static electricity discharge; could it be possible i zapped the system? It's cold, dry, and I have a lot of carpet!

If I were to replace the MOBO with the correct replacement unit(assuming the video or other critical component is shot), would the windows HAL recognize it and function properly?

Thanks a lot everyone for trying to help me solve this!

Remove the motherboard out of the case, reset bios by remove the coin shape battery for few mins, then install basic components and power up see if it works?

Seems that the motherboard is failed.

I actually just disassembled/reassembled the unit, reseated components, etc. I was looking for the bios batt, but didnt' see the typical coin shape one. The only thing I saw that came close was a small round magnet looking something...but could not unseat it, so I left it be. any ideas?

Thanks

Motherboards from Dell, HP, etc. are sometime not standard motherboards that you can buy from retails. If you can put a picture here, that would help a lot :o)

Remove motherboard out of the case, and place on cardboard to test though. If it is still cold while power on then you could rule out (not 100% but close) the motherboard issue.

Sadly, this I know :( , however I know the part number: 431363-001

I'm not sure I understand what you mean here...could you please elaborate a little??

Thanks

Take the mobo out of the case, you can avoiding possible electrical short from motherboard to chasis, and you can also inspection overall the motherboard for any issue might occur (bad caps, burn mark, etc.).  

Oop! sorry. I got wrong since you are talking about laptop, not desktop.

Yeah, I thought I had posted this problem in 3 different sections, but alas, only the Desktops/PCs/ section have appeared to reply...

Back to another question, regarding replacing the MOBO,  I have potentially lined up a potential replacement. Will the exact replacement( i.e. sys board; graphics module, etc.)allow my HDD and Windows HAL to function as if all components were the same? Id I replace the guts, will the HAL reject the transplant, so to speak??

Thanks...
