I had trouble looking up that model on the HP page, but you should check this page and see if this model is affected by this NVidia litigation. If it is, you can get it fixed/replaced on NVidia's dime.

Good luck!

This will be legit Bryan, but it may be something you do not wish to read.

The HP Pavilion dv2000, Pavilion dv6000, and Pavilion dv9000 series of Notebook PC's, share a common problem.
(There are other HP's, and Compaq's that fit this 'ailment' also)

The cooling for the graphics chipset is inadequate. Causes exactly what you are seeing, or lack thereof.

This is going to lengthy, advising you in advance. I feel all info is necessary to explain the problem.............

1) Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The chipset used for graphics is a graphics chipset, or more properly referred to as the GPU.
Graphics Processing Unit,

The graphics chipset is mounted to the motherboard with a BGA surface mount. Ball Grid Array.
To explain the BGA surface mount;

Compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.
The bottom of the processor has 478 contact pins.
The processor socket has matching socket holes,

With a BGA surface mount there are no contact pins, nor socket holes.
In place of the contact pins are Solder Balls.
In place of the socket holes, (And socket), are Copper Pads.
(The copper pads are gold plated)

The graphics chipset with it's Solder Balls on the bottom, is set on the motherboard lining up on matching Copper Pads.
Heat is then applied at a specific temperature, and length of time.

This action melts the solder balls, and solders the graphics chipset to the copper pads.
(Which in turn of course, solders the graphics chipset to the motherboard)

The cooling components for the laptop consists of a Cooling Tube, Heatsink, and Fan Assembly.'25720'5478761930'44237177'1095196157'b'6412929857'tc''g'''&cct_ver=3&cct_bk=434985-001

Click on the image of the thermal cooling assembly to enlarge.

The Cooling Tube is the slightly flattened curved copper pipe that you see.
It is sealed on both ends, and filled with Nitrogen.

Note the irregular shaped metal plate attached to it on the right, and smaller metal plate on the left, near the Fan Assembly.

The larger irregular shaped plateto the Right, sits on top of the Processor.
The smaller plate sits on top of the GPU. (Graphics chipset)

The Fan Assembly is the black curved fan blades you see, (Fan), and it's surrounding black D-shaped shroud.

In the front of the Fan Assembly is a rectangular finned Heatsink.

Heat is absorbed by the two metal plates sitting on top of the Processor, and graphics chipset.
The heat is then absorbed by the Cooling Tube.

The Cooling Tube transfers the heat up to the Heatsink, and it radiates the heat away with it's thin fins.
The Fan Assembly helps carry heat away from the fins of the Heatsink.

The area of the small plate of metal sitting on the graphics chipset, is too small. Cannot properly keep the graphics chipset cooled.

(The Processor and the graphics chipset, are the two hardware components inside a computer, that give off the most heat)

With inadequate cooling the graphics chipset overheats.
Remember those Solder Balls, and when they melted they made a solder connection?

They start to partially melt. Soften up.
Then when the laptop is turned off they re-solidify.
This creates a Cold Solder Joint.
(Solder connection = solder joint)

A cold solder joint creates a bad contact. In this case, a bad graphics chipset to motherboard contact.

No graphics.

Can it be repaired? Sure. But if the cooling surface area for the graphics chipset is not increased, you will be right back to square 1 where you are now.
Without increasing the surface area it's just a temporary fix.

This is one tech's idea of how to permanently cure the problem.
I'm not advertising for him. I don't advertise for anybody. It's for reference.

I believe the best method is to use extra surface area as he has shown, but use a BGA Rework Station to properly resolder the graphics chipset, back to the motherboard.

I will say I read in one of this gentleman's videos, that he also believes the best method is to use a BGA Rework machine.
(He has three videos specifically dealing with the Pavilion dv2000, dv6000, and dv9000 series of Notebook PC's)

For additional questions please post in a Comment.

[ If you do wish to take this on Bryan, I can post a link to a free Service Manual, pictorial disassembly guide/s, and proper procedures for disassembling from me ]

SOURCE: HP G62 black screen on start up

If it has no "ghost image" on the monitor, nothing, it could be a connection issue, a ribbon cable on the rear of the monitor, the inverter, a tiny switch the operates the on/off of the backlighting when the lid is opened or closed, sometimes located near the lid hinges. Have you tried a External Monitor? Take a look at this video, it may help troubleshoot the issue:

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/

Unplug the unit, and remove the battery. This will shut the machine off completely. You do not need to let the battery die out. Then power the unit on again. If the issue is gone, consider turning off hibernation ( power options inside control panel)

Hp 6000 notebook screen goes black..... blue control lights go on and off

if i'm reading this correctly, it sounds like it could be a motherboard/video issue. If that's the case then unfortunately you are probably going to need a new computer if it's out of warranty...

for now however, try shutting down the computer and removing all power (power cord, battery) for a few minutes, then plug it back in and try to boot.

Completely remove the battery and unplug the power cord for a few minutes. Reinsert battery and power up. You can also hit F8 when starting and see if you can boot into safe mode.
