Windows 10: Toshiba L750 keys: ` leftshift a b n keys not working suddenly

Hey Everyone

Started typing on my internal laptop keyboard today and reliased that mainly keys a b and n were not working.
So I decided to clean them by taking off the key and white holder, then used a cloth to clean all the dust etc.. both under the rubber button and around it. This still didn't work however, so I then decided to uninstall and reinstall the driver as well. However this didn't work either.

Its probably best to try and buy a new one off e-bay, but before I do this does anyone else have any suggestions?

Also interesting, a b and n seems to be a popular combination of keys for other toshiba laptops that don't seem to be working... (Using a USB keyboard atm to type which works fine)

Thanks *Smile

What is the make and model of your computer? How long has this been happening? Have you installed any new software or hardware drivers since you started experience this problem? If so, what are they and are they designed for Windows 10? Have you checked
the manufacturers website or contact support find out about compatibility, updates or support for Windows 10? Do you have a system restore point created you could go back to? Does the problem occur in other user accounts on the computer? Which version of Windows
10 is currently installed: 1507, 1511, 1607, 1703? Which version of Windows did you upgrade from? Awaiting your reply.
