My laptop's hinge is broken but the connectivity is still on. Can I replace only the outer case? If so where and how much would it cost?


Hi,

It is not the outer case only, the HP/ Compaq laptops outer case is very thin fiber, from inside you've a metal hinge and bar holding it. You can take it to a local store to get it repaired. I would suggest if you have HP Accidental Damage Protection (ADP), you should call HP. They will replace or repair all accidental damages.

Regards,
Shrey

How do I take out the screen on my HP G71 -329WM laptop


I have a HP Pavilion zv6000 laptop and have replaced both the screen and the hinges, plus a few friends laptop screens all the same way. First remove the battery and unplug the laptop. To replace the screen you will need to to remove the hard drive and remove all the screws form the underside of the laptop to allow access to the underside of the keyboard as the connectors for the screen are under the bezel above the keyboard. Opening the lid all the way will make it easier to get under the keyboard t and bezel then disconnect the power, video signal, and wifi connectors. Might be 1 or 2 or 3 separate connectors. Carefully removed the rubber plugs from the front of the screen and stored them so you didn't loose them. Using a small screwdriver, remove the screws under the plugs. Using a flat screwdriver or small thin blade, carefully separate the bezel around the outside of the screen, it may be glued together so take care not to crack the plastic. At this point would can see the screen screwed in to the hinges and the back of the lid and what screws need to be removed. The wifi antenna is usually attached to both the screen and the lid via tape so take care when removing the screen. Place the new screen back and attach the hinges and connectors, making sure to place the wifi antenna back where it was located properly. At this point I plug in the laptop and verify the HP logo or POST screen appears whe I turn it on, showing that the connections are ok before unplugging and continuing to replace the remaining screws, hard drive and finally battery. Depending on how the bezel around the screen is attached, you might want to use double stick tape as the glue no longer holds the front and back together around the screen. Depending on how mechanical you are, figure between 30 and 60 minutes to replace the screen the first time.

Where do we find the display lid switch for a HP Pavilion dv9715nr ? we replaced a damaged hinge on this laptop first and now we cannot get a display.


Let me guess. Damaged Left hinge?

HP had a recall for this problem, but the recall has lapsed as of May 31, 2009.

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01611512

The Pavilion dv9000 series, also has a problem with the graphics chip overheating, and burning up.

Yes, I know. Just a regular ray of sunshine.

Graphics chip:
1) Chip is a slang term for I.C.
Integrated Circuit.

2) A graphics chip is a GPU. Graphics Processing Unit.

http://en.wikipedia.org/wiki/GPU

The HP Pavilion dv9000 series of Notebook PC's use Integrated Graphics, as commonly do a very large percentage of notebook PC's.
The GPU is mounted, { Soldered }, directly to the motherboard.

{Another term for Integrated Graphics is OnBoard Graphics.
On the motherBoard}

The GPU is an Nvidia GeForce 8600M GS, that uses the PCI Express technology.

The cooling system of this laptop (Notebook) has a poor cooling design for the GPU.

This causes the GPU to overheat, and burn up.
There is no just replacing the GPU. The fix is to replace the entire motherboard.

I would like to suggest a simple test to see if the GPU is bad first., before going on to replacing the Lid Switch Module.

Hopefully it is just the Lid Switch Module, or perhaps another simple problem I will detail. My thoughts at present, are that it is another small problem.

The test requires plugging in a VGA monitor to the back of the laptop, and seeing if the graphics are good.
(CRT monitor. Looks like a small television set)
Do you have access to a VGA monitor?

[ Bypassing the Lid Switch Module requires removing these components to access it;
1) Battery
2) Harddrive
3) Optical Drive
4) Switch Cover
5) Keyboard
6) Speaker Assembly
7) Display Assembly
8) Top Cover
9) Top Cover Trim ]

On the Left side of the laptop is a VGA port, to connect the VGA monitor to.
(Example of a VGA port:

http://en.wikipedia.org/wiki/VGA_connector

Coming from the back of the laptop on the Left side, it is the second port.

VGA monitor plugged into laptop, power on.
Hold the fn key down, tap the F4 key.
Give the VGA monitor time to, 'Come to life'.

VGA monitor comes on?

GPU is good, time to go on with the diagnoses.

The Display Cable also routes through the Left Hinge.
This cable has the graphics signal cable, and the power cable for the LCD Display.

(The Microphone Cable also routes through the Left Hinge)

This cable is very small, and could have easily been pinched, which could cause breakage of the tiny copper wires, inside the insulation sheath of the cable.

If it is pinched, this MAY be visible by observing the plastic insulation of that cable. The cable does get slightly squished with normal usage, though.

With the Left Hinge being loose, and is hard to open anyway, the cable could have become stretched.

This would cause breakage of the tiny copper wires inside, and the outside damage to the insulation of the wire, may not be so readily apparent.

It could also be that the connector that plugs into the motherboard, has simply been pulled loose, or is not tightly plugged in, and is not making a good contact.

I will include the link to the Service Manual from HP Support, in an additional comment.

I do suggest you buy, and wear an inexpensive ESD wrist s-trap, and connect the alligator clip to a good ground source.
(Average cost is around $6)

Continuity test indicates the Display Cable is okay?

( The Display Cable disconnects from the motherboard, and from the Inverter, that is located in the Display Assembly.

The Inverter is what converts power for the LCD display screen, and also the Backlight Lamp.
The Inverter is a small circuit board, located behind the Display Bezel of the Display Assembly.

Cable disconnected from the motherboard, and from the Inverter, a continuity test of the Display Cable is done with a multimeter.

The multimeter is set to the 1K, or 10K scale.
An economical, but decent enough multimeter for this type of testing, can be purchased for around $12 to $15, from a local auto parts store )

Okay, now it's time to replace the Lid Switch Module.

I will give the link to HP Support, and the Service Manual for the Pavilion dv9500, dv9600, and dv9700 series, in an additional comment so you can disassemble the laptop to access the above.

Below is the link to the service and repair manual. The schematic of the main bosrd is in the "B" appendix. Open the file, it is a pdf file and scroll down past the disassembly guide, When you get to the appendixes, it will be on B-1 and B-2, that will show the top and bottom of the board.

Is it straightforward to tighten the hinges on my samsung nv5000 laptop? The lcd won't stand up on its own any more! Many thanks, Rob


Should be, just need to be careful when removing the cover..

The notebook is quite old so you may find the plastic or metal has just worn and the hinges need replacing.

2 options:
1. Buy new replacement hinges.
2. Insert spacers in the hinges.

Presario laptop hinge broken. How do I remove the bottom section of the hinge?


Well since we don't know what model presario you need help with, go to this site and search for tech manuals. once you find the model read what the manuals are for e.g. service manual.

Read carefully these might be multi-part manuals 0-5

read carefully the printing on the page is small and it is easy to overlook the "To download file please click here"
