not difficult..with right tools and patience..the touchpad is part of the upper assembly, and requires that the bottom be removed. When I do this, it takes around an hour.

SOURCE: 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.

SOURCE: i spilled coffee on to the keyboard of my compaq

Hi Dobbin,

Tell me you like coffee black, no cream, no sugar. That makes the mess less sticky.

First off, I'd advise against dismantling a laptop. Try this first:

Get yourself some canned air (several cans) and a good vacuum. I assume you've gotten as much as you're going top get from the K/B via paper towels and such.

What we are going to do is freeze whats left and **** it out with the vacuum. Use the narrowest attachment you have .

Use the tube that came with the canned air to get it between the keys. Hold the canned air upside down so the propellant comes out. This will instantly freeze anything it touches, including you, so be careful, where eye protection.

Do a little at a time, Freeze, work the keys, vacuum, freeze, vacuum, work, freeze, vacuum. Get the picture?

You can do this with th machine running, preferably with Notepad or something similar up. This way you can tell when the keys come back to life.

I know it sounds weird, but give it a shot. I ran a help desk where we got two or three of these a month. The canned air is a little pricey, but nothing compared with the cost of the laptop.

Good Luck,

SOURCE: spilled coke on my keyboard, how do we clean it


Thank you for your query

Best thing would be to get a damp cloth and simply wipe over the keyboard when the laptop is switched off, this will remove the stickyness.

Please ensure when wiping that no water travels into the keyboard which may cause you problems

I have a compaq Presario CQ57 laptop and cannot get the up/down etc arrows to work. Don't have a numbers lock key so I don't know how to get them to work again.

Here are some options:
1) Use an external number pad
2) Use an external keyboard
3) Replace the keyboard (a small Phillips screwdriver and a flat head are all that are needed.)

How do I disable the wireless key on Compaq Presario CQ57 keyboard ?

We have several terminals with keyboards that are used by different people during the course of the day. We had a similar problem with the Caps Lock and Num Lock keys. Solution(s): Straighten out a paper clip and make a quarter inch hook at one end. Insert the hook under the offending key(s) and pop it up. You can easily replace the key should there ever be a need. No ham, no foul.
