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.

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.

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.

Any suggestion on how to repair a broken plastic boss the hinge screws go into? My HP has metal inserts in those plastic bosses that are still on the hinge screws.
I need a product that will mold around the broken boss and fill space so the insert can’t break out.
I used such a product years ago. Epoxy won’t work because it creates heat as it cures.

Hi curt shumaker!
Right you are! Use 432963-001.

Well written instructions! Very helpful photos. Hinge replaced, all works well. One thing I did not do: replace the broken display cover. Didn’t seem worth the ~$35 to $40 for a new one. That may come back to haunt me, but so far, so good. Thank you!

Thank you for your clear directions. I was able to replace the broken left hinge on my HP dv 9000. Your step by step directions were extremely helpful in the repair and getting my system back working…

@ ank,
Remove the screen bezel and you’ll see the inverter board mounted under the screen.
Take a look at the right side of the inverter.
If there is only one white connector plugged into the inverter on the right side, this is single CCFL screen.
If there are two white connectors, this is dual CCFL screen.

Thank you! I was able to fix the hinge. I did have to make a second repair because I ended up crimping my video cable when I put the hinge cover back on. I had the additional symptom of a black screen when booting (but the backlight still engaged). I could get an image with an external monitor I replaced the video cable and it is good. Also, if the screen turns white…. you didn’t plug the video cable back in firmly (I had this happen too)
Thank you so much! I was able to spend $50 and get my laptop fully functional again instead of shelling out a grand for a new one!
