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.

In the step 9 I found that I have 432949-001 screen installed in my laptop, so I have to use hinges and cover for screens with single lamp.
You’ll find part numbers for display hinges and display cover (enclosure) on the page 87 in the same manual.

LK Tucker, the product youre thinking of is J-B Weld the Original Cold Weld Formula
Steel Reinforced Epoxy.
Worked good for me, with same issue as you, the little copper screw cups were attached to the screws, with some broken plastic that i removed.
Nice specs on the 9000′s but between this hinge (funny that the hinge that breaks for everyone is also where they decided to place the chain lock, which i have never used, but broke anyway) and the nvidia overheatting issues… HP should stand for Help Product, cause some of them really need some help.

Right hinge in HP laptop pavilion dv 9000 broke twice — the same hinge. I sent it to HP for repair and I was charged $190. The second time the same hinge broke, HP did not want to fix it. Later I found out that there was a RECALL due to defective hinge in my model, and I requested my money refunded for the first time, but HP did not want to refund it. I talked numerous times and hours with Case Managers but it was futile (waste of my time). So, recently I bought a hinge through Amazon for $9.50 and fixed it myself using this tutorial. Thanks for posting it. And I will never buy another HP product, and will dissuade many buyers to avoid HP computers. In sum, HP CEO Meg Whitman does not know the meaning of “corporate good will”, that’s why I predict HP will soon go out of business !!!

I did the hinge, broke the cover bezel, but hinge is good now

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.
OOPS !!!
Now what? It seems that it was way to short to flip it upside down on the keyboard. I can’t even get enough slack to replace the ribbon into the slot without micro fingers or eyes.

One thing to consider when ordering a replacement part is whether or not the laptop has a webcam or not. This will change the front bezel part number which may or may not be included with the back bezel.

Well done, this is a very thorough tutorial. I have some computer repair experience, but I think even a beginner could figure it out with a little effort. Thanks!!

I got to this site looking to check how to replace the wiring on the left side hinge. It seems that it has a short and can’t open the whole display unless I press the wires manually. They are right under the hinge and the opening of the lid/screen mechanism has fried the wiring. Is that the so called flex? how can I replace them?

I found the following comment on another forum (and another HP laptop) that I thought might be a more helpful way to determine if a laptop has a single or dual lamp. Would this be an appropriate method for a DV9000?
“I recently repaired a computer just like this and it was almost the same model. Remove screen bezel by first removing the screws and screw covers (5 each). Carefully use a small flathead screwdriver to pry open the bezel (wrap tape over the head using regular scotch tape to protect the bezel and cover finish) from around the screen. Underneath the screen, you will see an electronic board (Inverter) and it will have a 4-wire connector on the left side and either a 2-wire connector with a white and pink wire going into it (single lamp) or two separate connectors (one with white/pink wires and another with black/blue wires). This would be a dual lamp.”
My DV9000 has a single connector with black/blue wires on the right side so I would have a single lamp display.

@ LK Tucker
Jeder Vorschlag, wie ein gebrochenes Kunststoff Chef die Scharnierschrauben in gehen zu reparieren? Mein HP hat Metalleinsätze in diesen Kunststoff Bosse, die noch auf den Scharnierschrauben.
Ich brauche ein Produkt, das rund um den gebrochenen Chef formen wird, und füllen Raum, so dass die Einlage nicht brechen kann.
Versuch es mit Flash bonder Reparaturknetmasse von Henkel. Erst stück abschneiden dann kneten und dann drumformen, Wird hart und ist dann bearbeitbar mit Bohrer, Feile,usw.
Hat bei mir wunderbar funktioniert.
