In the following guide I explain how to replace the left hinge in a HP Pavilion dv9000 laptop.
Broken left hinge is a known issue with HP Pavilion dv9000/dv9100/dv9200/dv9400 series laptops. A while ago HP was fixing this issue at no charge under the service enhancement program. This program has expired on May 31, 2009 and now you are on your own.
I believe this guide will work with some other HP Pavilion laptops even though replacement part numbers can be different. If it works for you, please mention the laptop model number in the comments below.
I will explain how to find correct parts for this repair at the end of the guide.
STEP 1.
Remove six screws located in the battery compartment. These screws secure the switch cover.
STEP 2.
Remove the switch cover and place it upside down on the keyboard. Be careful because the switch cover is attached to the motherboard via a flat ribbon cable.
For more detailed instructions for removing the switch cover please check out my previous guide about removing the keyboard.
STEP 3.
Remove five screws seals from the display bezel.
Remove all five screws found under these seals.
STEP 4.
Remove display bezel.
You’ll find more detailed instructions for removing the bezel in my previous post about removing and replacing the LCD screen.
When you remove the display bezel, you can take a closer look at the left hinge damage.
STEP 5.
Disconnect the screen backlight connector from the right side of the inverter board.
Remove six screws securing display hinges. Three screws from each hinge.
STEP 6.
Now you can separate the display cover from the LCD screen and access the video cable.
Remove sticky tape securing the connection and unplug the video cable from the LCD screen.
STEP 7.
Remove two screws from each side of the screen. These screws securing the LCD screen to the hinge brackets.
STEP 8.
Remove the LCD screen.
STEP 9.
Remove three screws securing the left hinge.
By the way, the display part number is located on a sticker glued to the video cable connector. Write down the display part number because you’ll need it later in order to find correct hinges for your laptop. In my laptop the display part number is 432949-001.
STEP 10.
Remove the left hinge assembly from the laptop.
STEP 11.
Separate the hinge cover from the hinge.
The broken left hinge is removed and ready to be replaced with a new one.
Unfortunately, in my laptop I found another damaged part, it’s the display cover.
All four screw anchors are missing and if I assemble the display panel like that, I will not be able to screw the left hinge to the display cover. The display cover has to be replaced too.
After you remove the LCD screen, it’s very easy to replace the display cover. Simply unglue the wireless card antenna cables, microphone cable, webcam cable (if you have any) from the cover and replace the cover with a new one.
How to find new hinges and display cover.
HP uses different LCD screens in Pavilion dv9000/dv9100/dv9200/dv9400 laptops. Some LCD screens come with single lamp, others come with dual lamp.
I found all LCDs listed in the service manual for HP Pavilion dv9000 and dv9200 on the page 151. By the way, for dv9100 and dv9400 HP links to the same manual and I assume you can use same part number for these models too.

Hello, I am trying to fix my laptop with new hinges. I got them for the second time which I purchased on ebay. They seem to fit but they are hard and lock, they don’t rotate at all so I don’t know how the cover will close. Are the hinges suppose to be like this or they are totally a waste. Could you let me know if I have to put some oil or do something different. Thanks

Completed repair August 29, 2010….your pics were identical to what I found inside my HP Pavillion dv9000, including the bottom left side LCD cover damage where the fastners are placed.. Well done with these instructions as I would not have attempted such a repair without your guide. I also used your guide to order the new LCD cover, again would not have known the correct part to order without your guide.

So if you’re also replacing the right hinge: It’s a little different. Only one screw in front during step 9. 2 more screws underneath the hinge, in the battery compartment. I really had to wrench the plastic hinge cover off too. But all other instructions should stay the same.

Thanks. My Right hinge broke on my hp pavilion 9700. I ordered the replacement part of of ebay for half the price of hp and used your directions. I fixed it myself and only spent $38 on the part by doing it myself. Thanks a bunch.

BigD,
It’s hard for me to tell without looking at the laptop.
If your hinge looks like one shown on the second picture in the step 11, it definitely has to be replaced.
