Thanks for the great guide. My hinges were shot, and this made replacement a lot easier. My only problem was that the inverter connecter was so tight that it wound up pulling off the cable instead of the board and I had to find a replacement cable (fortunately, a cheap one). I’ve found a few people who had the same problem, so be careful, it comes apart easily. If I were to do this again, instead of removing the video cable from the screen and inverter, and then having to re-attach and re-tape, I’ probably just undo the single screw holding the cable to the lid (at the hinge), and lift the screen and cable out as a unit. Less work, and less chance of messing things up like I did.

Thanks again,
Peter

Mack,

my dell latitude c840 has a screen problem. When i turn it on the screen comes on and u see windows loading. When it goes blank to switch to log in screen it never comes back on to log in. But i did notice that the screens backlight was on. I put it in safe mode w / networking and it started to start up but the screen just froze or the laptop just stoped loading wondering could this be a hard drive issue or what could cause this to happen

It’s hard to tell what’s going on without testing the laptop. Could be software or hardware related problem.

Do you have any important files on the hard drive? If not, just run the Windows installation CD and reinstall it from scratch. After that run the drivers CD and install all missing drivers. It could help.

If you suspect the hard drive failure, you can run the hard drive test. I use Hitachi’s drive fitness test and it works fine for most laptop hard drives (even non Hitachi).

This is helpfull. I had to replace only the right hinge. I did it without copmletely removing the panel and the keyboard. The hinge can be replaced by only removing LCD bezel and the keyboard bezil.

Chad,

This question is not related to this section but I couldn’t find anywhere else to post in your website. I have Dell Inspiron 1525 and left side screen hinge is broken. Do you have any thing to show how I can repair it or replace it. Really appreciate your help.

Here's a link to the official service manual for Dell Inspiron 1525. The manual has instructions for removing and taking apart the display panel. You can use it for accessing and replacing the hinges. The broken hinge has to be replaced with a new one, you cannot repair it.

Great guide. If these instructions are followed in order and you take your time its a rather painless process. I was able to swap out my hinge in roughly 30 minutes and that included removing parts from a donor system.

debbie,

Will this tutorial work for a Dell Inspiron E1405? If not do you know where I can get instructions for that?

Here is the service manual for Dell Inspiron E1405 or 640M laptops.

My screen is so loose that it just flaps all the way back and has no more resistence, I cant use it unless it prop up the back of the screen, either that or I type with one hand and hold the screen up with the other hand.

Apparently one or both display hinges are broken and has to be replaced. You cannot tighten broken hinges, you'll have to replace them.

I have heard conflicting opions on just removing the plate at the tope of the key board and the bezel plate around the screen. Some people say you have to take the whole thing apart, others say you can just take plates off and tighten screws. What is your opinion.

If the hinges are broken, you'll have to remove the display panel and disassemble it. You'll find pictured instructions in the service manual I linked above. In order to removed the display assembly, you'll have to 1. Remove the keyboard cover (hinge cover). 2. Remove the keyboard so you can unplug the Wi-Fi cables from the Wi-Fi card and unplug the LCD cable from the motherboard. 3. Remove screws from the display hinges and remove the display panel. 4. Remove the display bezel, access hinges and replace them.
