Windows 7: Serious keyboard issues - keyboard has a mind of its own

Serious keyboard issues - keyboard has a mind of its own

Hi everyone.

I have been experiencing serious keyboard issues since Friday on my dell inspiron 1420 laptop.

Goes like this:

Only the keys 5 and 6 work in the numbers row
windows button does not work
Most of the time i can type with my all my letters, but sometimes, pressing letters such as D, E, W executes the windows shortcuts automatically.
For instance, usually to head back to my desktop I use "windows button + D" - with my current problem sometimes only pressing on D will activate that shortcut - and this goes for all windows shortcuts basically making it impossible for me to use my keyboard.

Then sometimes my whole system is going haywire i.e volumes going up and down for no reason, windows that are closing and opening, pages refreshing, exporer opening up for no reason etc. - as if there was a faulty electronics problem randomly activating those buttons.

I have tried to load my system in safe mode but the problem still remains.
I have also just re-installed windows 7 and the problem still remains.

I am almost sure this is a hardware problem - faulty electronics regarding keyboard control

I dont think this is a virus or a malaware issue because re-installing windows did not help.

On another note, while cheking theweb for solution, it has been brought to my attention that other people have this problem (number keys not working except the 5 and 6 ones) and I have yet to find a solution or an explination.

Can anyone help me out?

Thanks

Have you tried plugging in an external USB keyboard to see if it exhibits the same problem?

If it turns out to be the keyboard, they are available on Ebay and fairly cheap to buy. They aren't difficult to install, usually just a couple of screws.

Here's an example of one on Ebay: New-Keyboard-Dell-Inspiron-1420

hi yambo, and welcome to sevenforums,

sometimes keyboards need a good clean - there's invariably hair, bit of dead skin/god-knows-what-else that accumulates under the keys and can lead to problems when typing.

try giving it a good scrub with an old tooth-brush, with the keyboard help upside down.

failing that, as strollin says, it's cheap to buy a replacement keyboard and pretty simple to fit - you will be able to download a free dell service manual with handy drawings of the process.

all you need to do is undo some screws and then there is only one internal connector to worry about, as below. screw it all back, and the job is done.
