Keyboard and touchpad not working after restart. Windows 8 Sony Vaio T Series Ultrabook.
My Sony Vaio T Series Ultrabook running Windows 8 had frozen while running a program. Task manager wouldn't work, so I used the sidebar on the touchscreen to restart. After I had restarted, neither the keyboard nor the touchpad were working besides the
backlight of the keyboard. I tried to use system restore to go back a couple days, but no success. In my device manager, there are yellow marks next to my keyboard and touchpad. External mouses don't work either! After troubleshooting, it says my computer
is having trouble with PnP devices. I can only navigate my computer with its touchscreen and it is very tedious. I need this computer to type for school. Please help!
