How do I replace hinges on compaq nc4...




By pjl1000 on Oct 31, 2008

" "
One display hinge on the laptop is broken. I have replacement hinges and covers.

It looks as if I have yo take the cover off the LCD. Does this just prise off or is there a another way?
Comments:

Oct 31, 2008

- The response is not an answer to the problem. I have spare hinges (see posting). To be advised to go to e-bay to buy some more is hardly helful. My question on how to fix the new hinges was ignored.

Oct 31, 2008

- I am afraid that I do not believe this advice. The hinges fit into the bottom of theLCD display unit. Removing the keyboard and/or the LCD cover would get you n further. I really would like advice from someone who has replaced these hinges

Oct 31, 2008

- To Ekse
I have read the manual. The pages you refer to describe how to remove the whole display unit from the computer - which is not relevant. They do not describe how to replace the hinges into the display. I have since found a brief respons from 2007 which confirms that the display has to be gently prised apart.

Oct 31, 2008

- Ginko

What you advise is not relevant. The problem is not to unscrew the hinges from the chassis. This is entirely straightforward and does not require anything other than the hinge covers to be removed.
The problem lies with the other end of the hinge which fits into the lid.

What is the procedure for removing the screen front cover?
That is the advice I have been seeking throughout. I have the manual that you quote and it does not address this point

Nov 01, 2008

- The original question - still unanswered by anyone -is hpw do I remove the front cover of the LCD display. This is not described in the service manual which I have.

It would be really helpful to have a response from someone who has actually replaced these hinges.

Nov 01, 2008

- Ekse
This does not address the problem asked

Nov 01, 2008

- Does not address the question asked

Nov 01, 2008

- Does not address the question asked

Nov 01, 2008

- This is more helpful. There are no obvious screws holding the fromt of the LCD display. There are small "rubber" dots. Do they need prising off? The cover does not come off readily and I am hesitant to use force.

Nov 01, 2008

- The final response was helpful. However it is obvious that none of the repondents have actually replaced broken hinges on this model of laptop - and this makes the advice less than compelling

the lcd screen should have screws on the sides of the screen all the way around , that is how you will get to the screws on the inside for the hinges ,when the caps are popped off of the hinges there should be two screws per side and also the plug for the lcd screen should be on the left side be careful when lifting up on the plastic part of the plug and be careful of the wires attached
once you have the hinge unsrewed and the plug detached you should be able to take the lcd screen out and work on getting the screws out of the side of the lcd screen , once you have the screws out of the lcd screen be careful when seperating the two pieces , then you should be able to get to the hinge screws on the lcd screen , after that its just putting on the new and putting it back together

- if there are no screws then the lcd screen will have to be carefully pried apart

Nov 01, 2008

- on the front of the lcd screen , the plastic that covers the front sides will be pried off from the side of the screen then there will screws holding the lcd to the back side of the screen , remove those also

Nov 01, 2008

- you will need to at least take the the cover off positioned just below the screen( power button , led light , speakers cover) to get the lcd plug out

Nov 01, 2008

- if there are little rubber dots then those have to come out and there will be screws under them

Nov 01, 2008

- unfortunately we cannot have hands on every device that is out there ,but knowing that there only certain ways that they can be put together and from experience there are many ways they are constructed on all the different types, there is no specific way that they are all put together
if you are not satisfied with this cheap way of getting help then ask for your money back
sorry you are not satisfied

You have first to remove the keyboard and the cover, then you proceed in replaceing the hinges.
Comments:

Oct 31, 2008

- Lol, I have replaced the hinges on that and some other hundred laptops like that, that is what I do for living. Now Fixya works with short answers, then follow this hint.

If you are interested here is the service manual, For detailed procedure , follow the service manual here (click), check page 117, it says:

1. Prepare the notebook for disassembly
2. Disconnect the antenna cables from the Mini PCI communications board. instructions.
3. Remove the LED switch cover
4. Remove the keyboard

4. Remove the keyboard

On some models here you remove the hinge covers.

Once you remove the keyboard, you reveal hinges screws that mount on the chassy, undo them and free the hinges.

Oct 31, 2008

- To replace hinges you have to undo the whole display assembly.

Oct 31, 2008

- To remove the other end of the hinge on an HP/Compaq you usually have to remove the screen front cover, sometimes also the LCD display, as the hinges are screwed onto the back panel.

I have assembly instructions for most of them.

Oct 31, 2008

- More , on the 4000 series you also have to unscrew the two scrws that keep the hinge covers to access the hinges.

Oct 31, 2008

- Here is the procedure:









That is all you need to do.

Nov 01, 2008

- It is obvious that you should keep comments on experts for yourself.

You do not seem to have understood muck from presentation given, it is obvious that not all users read carefully comments, and it is also obvious that is impossible to work seriously with the current system.

It is obvious that I do not maintain my family answering to you on Fixya, therefore it is obvious that I have another job.

What do you think I do for living , the pastry chef?

It is obvious that once again you should pay more attention and read carefully what had been told you in previous comments.

You had at least three persons here that disassembled that old laptop of yours before.

Thanks for using Fixya.

Obviously and obnoxiously goodbye.

Hi,

On most Compaq units we have worked on, the front plate of the display is held by 5 special screws. These required the use of a T-9 Torx driver. The location of the screws are underneath the small rubber pads on the four (4) corners plus one center top. The panel and the back cover snaps together and needs to be pried apart using a thin spatula type tool to separate. It helps to have another of this tool to keep the side/areas already parted from snapping back together while working on the other side.

The hinge could either be part of the LCD bracket or attached to it. There would be no less than 3 screws holding the upper part. In some models the bottom part is slide in with two (2) screws at the rear of the laptop itself. In some instances, the rectangular panel above the keyboard has likewise to be removed. Some have screws some are just snap together.

In important note is not to bunch the screws together. Often they come in different lengths or threads.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

- I have to add a few notes:
  • no matter how careful one is, there would be instances where there would be scratches/cracks;
  • in some instances, it is not the hinge that is the issue but the backing plastic base that holds the copper/brass inserts that serves as nuts;
  • in some emergency repairs, a nail pusher from a manicure set also serve the purpose as the spatula.

- Replacing broken laptop hinges takes a lot of time because you have to take apart two major parts – the laptop case and the display assembly. For removing the top cover assembly you can follow these instructions. To open up the display assembly, check out guides for other models on www.irisvista.com. If you decide to open the laptop, be very careful and document each step you make so you have no trouble assembling it back. If you are not confident, do not open the laptop or you can damage it permanently.
