M645-s4070 keyboard not working

The keyboard on my Toshiba Satellite m645-s4070 has stopped working; 1) I removed the keyboard from the control panel , hardware configuration, and restarted the PC to reinstall the keyboard, did not help (Control panel shows that the keyboard is working properly) 2) I deleted the driver and searched for a new keyboard driver on line did not help, system shows that the most recent driver is installed. 3) I ran Spybot search and destroy in case the problem was spyware , did not help 4) I ran Ccleaner to check the registry , did not help 5) I went to the BIOS to see if the keyboard would work outside the O/S environment , does not work 6) Installed a wireless keyboard, and it works Anyone have any other software suggestions before I assume tha it is a hardware issue and order a new keyboard? Also does anyone have the disassembly instructions for this model? Thanks Don B

This has been a common windows issue. I'm sure that this will solve your problem. You can go to this link,, download the registry file and run it. After that, just restart your computer and it should be good to go.

If you're not sure and is worried about security since this is messing with the registry, you can just click on this microsoft link where it explains and gives you detailed instructions on how to manually edit the registry and fix the problem.

This is typically the same thing, the first one is just a shortcut on how to do it. Just a reminder, EDIT THE REGISTRY AT YOUR OWN RISK!!!

They don't list an XP driver for your model. Based on diljale's comments, though, I was able to discover that Atheros uses a single driver for all of its models, and he says you've got an Atheros card.

The direct download link, which may even work, is here:

If that does not work, go here:

Pick operating system XP
Pick All Categories, and scroll down to Wi-Fi (It may be so far down the list it won't show on your screen).
Find the first/latest Atheros Wi-Fi driver and you should be in business.

You may also wish to consider visiting and downloading the free software there, which attempts to tell you which drivers are out of date and tries to offer download links to the newest versions. RadarSync has many many flaws, but it can sometimes be helpful.

Click on the Downloads tab and then choose windows xp as your operating system and you can download any of the drivers that you need from that point.
