Need to know the number of beeps. They're called beep codes. This page lists some of the Compaq beep codes and what they mean.

It seems that your notebook does not have sata connection to Hard drive. Your harddrive is IDE connection. Sorry but you can't use SATA on this laptop.

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.

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

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.

it's not safe to do that alone.
It's LCD, you must not touch it.

It's impossible to replace alone.
If your laptop still under warranty, send back to the warranty.
They will replace it for it.

If not, send to any computer shop, they will know how to repair it.
LCD is different with a normal monitor, you shouldn't touch anything on it. It's very sensitive.

If you look on Google, there are sites that have step by step instructions on how to do it.

that happens to me all the time too. it will randomly shut off and i wont be able to get it on again till a day or two later
