Laptop keyboard some keys stopped working

[oekoeloe]

Hello,

Some of my laptop keys stopped working over night.
There's been no damage done to them and they are clean.

Here's a picture of the keys that work and don't work:
Green = works
Grey = doesn't work

F1, F2, `, 1, q, a, z

What I tried so far:
Using the on screen keyboard does work.(That's how I type the 'A' letters right now)
Uninstall keyboard drivers and reinstall.
Discharging the laptop by disconnecting it and holding down the power button for a minute.
Check the connector to the motherboard, it was fine but I don't dare to unhook it to reseat it just now.
Changing the language of the keyboard

Does someone have something else I could do?

Thanks

Disconnect the keyboard and reconnect it. If that doesn't work then you'll need to replace the keyboard. eBay is a good place to look for replacements. You should only need to spend $25 max.

So, I disconnected the zif connector and put it back. Booted the computer and still nothing.

Here's something I found on ebay. I have HP 6730b.

Is there a program that can check wether a key being pressed is sending out a signal?

All I programs I found only check the corrosponding letter or number. I want to know if the button is sending out a signal at all.
