My next door neighbour just gave me his laptop to have a look at, an HP Pavillion DV6000, which his baby has managed to 're-adjust'
Apparently his baby was bashing away on the keyboard and now when it is switched on all keyboard lights come on, the laptop makes 3 very loud and intrusive beeps (beeeeep....beep.beep) and the screen is completely dead, no flickers, no nothing.

Any idea what the problem could be and how to resolve it?
 
Well, the beep code tells that there is a video error. Which makes sense for not getting video.
So you may need to swap out the video card, or check the connections to the card.

That sucks... sounds like damage or cable loose in the main unit. Did the child pour anything into it as well?

Also, did you try hooking to an external monitor?

May need to pop open the box and take a look inside. I've never worked on any HPs', but many Dells and IBMs - both of which are very servicable and have good tear-apart instructions.
 
Get a torch and shine it on the screen and see if you can see the graphics on screens id say the back lights are gone or like CD said. Hook it up to a monitor and see if you get a display like Sas said.
 
Make sure the memory didn't come loose from the connectors. Those things can come out pretty easily if the laptop is being bashed on.

Though the beep code definitely points towards a faulty video card.

It is also worth noting that the DV6000 was recalled due to a bad BIOS that caused the video card among other things to overheat: http://h10025.www1.hp.com/ewfrf/wc/...77&lc=en&cc=us&dlc=en&product=1842189&lang=en

You might want to check to see if his laptop is one of the affected laptops, he might be able to get it replaced under the recall.
 
Yep, just tried it on the TV and it gave me a 'no sync' but that could be a resolution problem but with no laptop screen I can't ascertain that.

No liquids involved just a good key mashing.

No luck with the torch.

I'm gonna take it apart.

Would probably be the best next step to do. Should tell you what the problem really is.
You may have to look closely if nothing seems out of the ordinary when you get it apart.
 
I've just done a strip, couldn't get the upper fascia off, but I checked things over as best as possible so far.
The result so far is, is that I now no longer get any beeps, the start up is nice and smooth i.e. hard disk etc but I'm still not having any luck with the screen.
 
The screen cable (a thin thin set of wires) might be unplugged from the mobo. Might want to check it is seated correctly.
 
Just looking over the screen wires and I've got what appears to be the signal wires, connecting to the right hand side of the screen, of which one is grey and one is black (RF type wires) which plug into a small board which then plugs into the Graphics card/ Mother board.
On the left side I have a single larger wire which could be a bundle or power, I don't know as it is wrapped in tape.
 
Most likely the connecting of the wires to mobo could be loose, so you are going to have to remove the mobo from the laptop because the wires are generally connected on the bottom of the mobo. And the word I am looking for is ribbon cable for the wire, but it could be different in your case.
 
These are the connections I've got. The top left connection is actually a multi-pin plug and the underside RF wires are as previously mentioned.

Also, after further messing about the beeps are back.

take out the keyboard, turn on the unit see if it post, he could've messed up the membrane on the keyboard thus the keyboard thinks the keys are being held down.
 
Keyboard is out and disconnected and still nothing.
 
the bottom pic is the wireless card, the wires are the antena.

the top pic is the plug for the monitor. also there is an inverter in the screen.

also the kiddo might have just popped the keys that disable the screen, some version of function and usually a number key.

(i do board level laptop repairs)
 
Ok, but if the screen had simply been deactivated by keystrokes would that also account for the beeps?
 
Even if he hit Fn + f4, i don't think the unit would beep like that,

i have noticed my fair share of dv6000 problems, including GPU issues. it may be coincidental but the GPU might have given out, i know DV6000 had a recall for this.

usually you do not hear beeping though.

Things to try before ruling this out

Reseat the ram. take both sticks out reseat them both, than try one at a time.

pull cmos battery out keep unit without power for 10 minutes (will reset bios).

If the laptop was running when the child bashed the keyboard and with the long beeps seems like memory is shorted or the memory connectors are broken. See if you can get hold of compatible memory or test one module at a time.

no, those are a beep error, look it up on the manual you can download from HP. i would bet it was a loose memory stick that has now been wiggled back in.

ive got a working dv6000 (amd) mainboard with a bad bios chip that could be repaired for about 50$

if your narrow it down to a bad video chip i can reflow the solder on it but it isnt a GUARANTEED fix. about 75% of the time it works.

yes, dv6000's are on the known list of being affected by the bad batch of nvidia chips.
 
Try reseating the large connector, that is the LCD connector. Also, try removing the wireless card.

No, HP just blaimed their issues on the bad batch of nVidia chips. The fact of the matter is that HP released these with bad BIOSes that didn't ramp the fan speed up soon enough and allowed the laptops to overheat. A simple BIOS fix from HP fixes the issue, if you catch it in time. The problem is that most people don't check for BIOS fixes for issues until it is already too late.

i've worked on many HP Dv6000 with updated BIOS and still got gpu problems, i do blame HP cause the design is flawed in my eyes. They blame the Ball Grid Array on the GPU. (basically same problem with 360 gpu's).

HP's are just bad laptops to me anymore anyway, i see far to many in this shop to ever think of owning one and not running the risk of it just not turning on one day.
 
I'vd tried reseating the Ram, swapping it around, single Ram and two Ram, no effect.

Tried removing the BIOS battery and erasing, no effect.

Large screen connector has been unplugged several times, no effect.
 
Did you try plugging the laptop into an external monitor to see if the gfx is still functioning? This would confirm my idea earlier about loose ribbon cable.

Did you remove the wireless card?
 
Tried it on the TV and got a 'no sync' which would indicate that there is no signal output.

Didn't try removing the wireless card, will try now.
