Disabling built-in keyboard

I have a Compaq Presario Laptop and I spilt tea on the keyboard a few weeks ago. I am using Windows ME.

The computer basically works OK but sometimes there are problems booting up - the computer complains about a stuck key, beeps continuously, shows the Windows ME screen and then just a flashing cursor.

The keys 'g', 'h', '-' and some function keys no longer work. I have solved the problem by attaching an additional keyboard.

I wondered whether there was a software way of disabling the built-in keyboard so that the keyboard does not cause problems in startup and just work from the additional keyboard.

If the computer doesn't automatically disable the on board keyboard when an external keyboard is installed then go into Setup at boot and look for an option to disable the on board keyboard.

1) I would check the bIOS for this, but on a laptop, it may not be available.

2) DOwnload the maintenance manual from compaq, and see if you can clean the keyboard.

3) Turn the laptop over and shake vigorously. This will get out all the crumbs etc that may be causing problems.

4) You might try removing the keyobard cable ( internal ) it is usually a flat cable. See step 2 for instructions.

I hope this helps !

Also, It may be possible to pop the keys out and clean under them.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Agreed. By default, a BIOS/Win configured computer must have a keyboard present and operational in order to complete the boot process prior to OS load. Most if not all BIOS's have an option available to disable this issue.
However, your situation is such that you do indeed want a keyboard, be it existant with your laptop, or external. Because of this, your options are somewhat limited, and a thorough cleaning of your keyboard(all power off for at least an hour) is warranted. By all means contact Compaq for assistance, as this issue though simply dealt with on a desktop system is just not the case with a laptop.

Thank you for your comments...

1.  I have checked the BIOS but there is no option to disable the keyboard

2.  I have popped the keys out and other than finding it difficult to put them back this has had no effect.

3.  I tried right clicking on My Computer to see the Hardware and then disinstalling the keyboard but this did not work and also the computer just reinstalled it next time round

4.  My computer is still under guarantee so I am slightly unhappy about opening it up and removing the keyboard cable.

5.  I have been quoted about $360 dollars to replace the keyboard by a computer shop.

6.  Crumbs are not the problem!!! I think that the liquid spills  must have shorted some connections.

Thank you all for your comments!

"My computer is still under guarantee"

Then what's the problem here?  Tell Compaq the keyboard isn't functioning properly so you want a new one.
