After I upgraded to Windows 10 on my toshiba notebook satellite L745D, most of the keys on the right side of the keyboard are now numbers. If I press function then the correct letter/ number appears. I've locked it into function mode but when I do that, the spacebar doesn't work. I've updated the Bios, the keyboard driver and have taken it in for a computer tech to take a look and they couldn't figure it out. So far the only solution is to use a wireless keyboard but I would like to have my keyboard working again. Thanks in advance for your help.
