Presario R4000 Keyboard removal

I have a small computer repair shop next to a large University, so I'm pretty familiar with Laptop repair. I an attempting to replace a keyboard on a Presario R4000 notebook. The problem is, I can't find how to remove the old one. I have the "control panel" off, all the screws out and the panel is loose in all areas except the very center where the power button is. Something is holding it there and of course, I don't want to force it and damage the plastic panel. Any suggestions will be appreciated!

Re: Presario R4000 Keyboard removal

The R4000 series bezel has a tiny tab on the bottom (keyboard) edge in the middle. You need to release the bezel from the hinge covers and pull/push towards the keyboard. this will release the tab.

Re: Presario R4000 Keyboard removal

Is this one of the keyboards that has the little plastic tabs that are springloaded holding it in at the top?

Replacing the keyboard

your only supposed to pull the hinge out carefully a small amount so the flex cable comes loose, then insert the new keyboards connector there and push them back into place. Its pretty much the same thing in all brands of laptops.

if you have broken the connector, you will probably be looking at buying a new motherboard unless you find someone to replace the broken connector.

Compaq Presario R4000 looses video and freezes after a while

The problem you describe can be caused by two different things. The two are not related to each other in any way.

The first, which is more common on desktop computers than laptop computers, is a thermal problem. The video chipset is overheating and causing a shutdown of the video. It is possible that this overheating is actually the cpu, but I don't think so, based on your description.

The second is the video power inverter chip. The power needed to keep the lcd screen lit up on a laptop is considerably more than what is needed to run the laptop itself. For this reason, a small power inverter chip is installed on laptops. It is usually found under the plastic bezal that surrounds the screen, and usually on the bottom. When this chip goes bad, the symptoms are as you have described.

Here's a couple things you can do before seeing a technician or teaching yourself to take apart your laptop. Plug in a different monitor; an external monitor and restart your computer. You should have a function option that will let you see two monitors at once. (that's the fn key, usually in the lower left of your keyboard). With two monitors showing exactly the same pictures, see if you can recreate your symptom.

If the problem is in the power inverter chip, the external monitor should remain on when the lcd monitor goes black.

If the problem is inside your computer (video or cpu overheating) then both monitors will go off.

good luck

Compaq presario R3000 not recognizing CD/DVD drive

I would try remove the optical drive and put it back in. It may not be very easy with your model laptop. There will be one or two screws holding it in place and I think they may be under the keyboard Its not very normal for that to happen when repairing a power socket. If they are a reasonable shop they should fix the cd problem for you. If they are like most laptop repair companies they will claim it wasnt their fault and charge you for it again. The cd drive will be held in by either one screw underneath the laptop or one or two screws under the keyboard.

I have a 2inch purple line displayed on my notebook-compaq r4000

was the LCD pushed on or hit in anyway? Damage liek that is almost always irreversible. If you have a warranty for the LCD now's the time to use it.
If you have any tech savy family or friends you can purchase laptop screens on auction sites fairly cheap($100-200), well as opposed to buying or paying the manufacturer (usually $500+) And do the repairs themselves.

If not then try a local repair shop as they will know best what to do.

There is no driver from Compaq because it just uses a standard driver from the operating system.

Try removing the keyboard from the device manager.

Then restarting the computer.

Let me know what happens.

Removal of laptop keyboard

Dear ctmom

Please find below the link to download the

HP Pavilion zx5000 Notebook PC, HP Pavilion zv5000 Notebook PC, Compaq Presario R3000 Notebook PC, HP Compaq nx9100 Notebook PC - Maintenance and Service Guide

( )

Removing the keyboard firstly requires the removal of the top plastic strip in order to gain access with the screwdriver to the four screws. To remove it follow the instructions at pages 137 & 138 and you are almost there.

Then on page 139&140 you will find the information to remove the keyboard. It explains all the information very analytically. You are simply unscrewing the four screws on the top side. On the bottom it is simply slided.

TIP: Be careful when you are releasing the keyboard up towards you. The flexi cable that is connected to the motherboard is quite short-fragile and does not have a lot of space to move so go slow until you have released the connector’s tabs and the cable is loose to be removed.

Please remember to remove the battery before you do any work in the laptop.
