Hi guys, I have recently installed an external keyboard to my laptop. This is working fine. But now my laptop keyboard won't work, with or without the USB one attached. Is there a way to fix this? I imagine it's a simple fix but I just don't know where I'm looking. I'f I try to type Office 365 on the laptop keyboard it writes: 6ff5ce 365. It's Windows 10 Acer. Any help would be greatly appreciated.
