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.
Display Assembly Spare Part Number Information
For use with full-featured computer models (includes camera, camera cable, and microphones)
17.0-inch, SXGA+, TFT Single Lamp with BrightView – 432947-001
17.0-inch, WXGA+, TFT Single Lamp with BrightView – 432946-001
17.0-inch, WXGA+, TFT Dual Lamp with BrightView – 432948-001For use with de-featured computer models (includes microphones)
17.0-inch, SXGA+, TFT Single Lamp with BrightView – 432950-001
17.0-inch, WXGA+, TFT Single Lamp with BrightView – 432949-001
17.0-inch, WXGA+, TFT Dual Lamp with BrightView – 432951-001
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 already ordered new hinges and display cover and install them soon.

GREAT WRITE UP!!! KUDOS to YOU!!
Caveats: The display spare part number was not indicated anywhere. But, since I also needed to replace the display enclosure (like everyone else), I noticed the spare part for the enclosure was for single lamp LCD. VOILA

I think you are my hero, really. I have the same problem that you explain very well with photos.
I was very disappointed when I discovered that HP closed the SML (service media library) where was uploaded a lot of video for disassembling Pavillion series. Now you have to be a registered partner to take access to library.
So today I decide to replace broken part alone, without any guide and at the end I found your very great page!!!, I believe that my dv9059ea has the bezel screwholes broken on the left. Hinge and enclosure too, by the same side, of sure.
So two question:
1 how can I find the part number for bezel?
2 do you suggest to buy it on ebay?
I hope you answer mw.
sorry for my english, i’m italian

Hello, This is a awesome write up! I have a screen with some lines through it when i move my LCD to view it better, so i’ll most likely be replacing the screen soon. My question to you is, #1, what do you mean when you say you have to replace the cover, in order to re-install the lcd? You mean the shiny peice that looks like it’s aluminum? Is this a must or can i skip it? (Actually re-reading everything, it sounds like you only replaced the cover because you needed to in order to replace your hinge, correct?)
#2, I have a loose left hinge, is their any issues with leaving it loose? It really looks like a simple task but I’d really rather just not fix it at all if it’s not going to effect my laptops performance, and/or mess up any connections to the LCD itself. Thank you for your time!

Kevin,
To be honest, I don’t know. I used original HP part number to find replacement hinges. Will it break again? I don’t know.

Miguel,
New hinges are usually stiff.
September 15th, 2009 at 12:37 pm
Hi Tech, I just got both right and left hinges and replacing them. Only problem is that they are really stiff and can’t move them to the correct position to installed them. Are they supposed to be this stiff? Thank you.

Tech,
Awesome write-up, really appreciate the help. I’ll add that in the laptop I was disassembling, there was no part number on the LCD screen cables. I found the part number for the display enclosure up near the webcam/microphone underneath the LCD screen, then matched that up with the part numbers you listed.
I had another question: All of these replacement hinges on eBay say they are OEM original — but we don’t want the original ones again, as they’re just going to break! Are these all redesigned hinges, with different part numbers than the original hinges? Some of them seem super cheap, but the more expensive ones don’t say they’ve been redesigned either.
Thanks,
Kevin

Mitko,
The right hinge is different but the replacement procedure is very similar.
Remove the plastic hinge cover and unscrew the hinge from the base.

Vladimir,
I’ll try to make it more clear.
1. Remove switch cover as it shown in the step 2.
2. Find display part number as it shown in the step 9.
3. Compare your part number with all part numbers listed at the end of this guide and find out if it belongs to LCD with single or dual lamp.
Still not clear?
All you need to know if your LCD has single lamp or dual lamp.
