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.

Static electricity can kill your laptop. I recommend wearing an anti-static wrist strap while working with internal parts of your laptop.

Kevin,
I think it’s possible and I’ve don something like that before but it really depends on the kind of damage. I cannot give you a good advice without looking at the laptop.

Hello There,
I seem to have run into the EXACT same problem you had. After pulling it apart (making use of the guide, thanks a lot), I have the left hinge broken in the exact same place as well as the back cover screw mounts broken.
I’ve already ordered a new hinge from eBay, but the prices on the back cover are ridiculous. I just paid nearly $500.00 last month to have the motherboard on this thing replaced after the video card fried it (not covered by extended waranty for my particular product number, hmmmmm), and I’m tired of throwing money away. Do you think it would be functional to just replace the hinge and then put it all back together, maybe with some krazy glue holding the enclosure screw mounts on or something?
I’m ready to run this thing over with a truck pretty soon…
Again, thanks A LOT for the guide, it made life a lot easier than if I were trying to follow the maintenance guide.
Cheers

I have a broken right hinge on a HP Pavilion DV6000.
I need to know where and how to order the correct parts for replacements.

Hey thanks a bunch. If I can pull this off ANYONE CAN DO THIS. I couldn,t find the sticker with the numbers on it but I found that the actual broken hinge has a number on it that I used to make sure I got the right one. For a single lamp the number is 3JAT9HATP05 or 25. It’s stamped on the hinge arm.
My wife’s gona sh** when she sees the laptop spread all over the kitchen table. I hope to get the hinges in a couple of days and I’ll let you know if I get it put together correctly again.

Ken,
The HINGE is the whole thing shown on the second picture in the step 11.
It includes the LCD mounting bracket (gray metal) which was broken in my case AND the hinge itself (black metal) which is broken in your case.
The whole think shown in the step 11 is called HINGE.

I need clarification on what is the HINGE. Your pictures seem to show the metal thing that goes around the edge of the LCD screen. That is not what is broken on my HP.
What broke on my PC is the black thing that holds the LCD lid to the metal spindle. Is that called the hinge too.
I took the part number off of the computer 448014-001 and it looks like it is the part number for the metal frame around the LCD. I don’t need that.
Take a look at this pic for more clarity.
