I was just playing Fortnite yesterday and all of a sudden, my character was stuck running and I can't Alt+Tab or see the light glow when I press the Capslock button. Therefore, I restarted my laptop assuming that it will fix the issue. But it did not. Some keys are not outputting anything, some are inputting the letters "z", "/" and "\". Like when I press the letters asd, it will output of "z\". I tried uninstalling my keyboard laptop in the Device Manager but it didn't help at all. Leading to a conclusion that it may be a software/hardware problem. Or a virus, but I scanned throughout my laptop and didn't find anything. I am using the on screen keyboard at the moment. Need help please

I am assuming by the mother board it is a TOSHIBA Satellite C55-C. What is the number after the C, Or what is the "Part number".Did it have any errors in the device manager for the keyboard? Have you tried an external keyboard?

I tried troubleshooting it but no errors were detected. Also, I have tried an external keyboard and it worked. I also noticed that when I press the Caps Lock in the external keyboard, both the external and internal keyboard Caps Lock light are glowing at the same time. But when I press the Caps lock in the internal, it won't glow/work. I'm sorry I can't see the number after the C or what is the Part Number since I'm at work. I will tell it to you once I get back home.

The actual number for it to be able to look in up on Toshiba's website is called "part number" like PSCP6U-01401E or similar .

Hmm, Toshiba's search is not the best, I had a hard time finding it but here is your support page https://support.toshiba.com/support/modelHome?freeText=PSCP6U-01401E
You keyboard could be a driver or a mechanical problem, anything spilled on it? (Satellite C55-C5268) May want to reinstall the system driver
Here is a generic troubleshooting video , its for windows 7 & 8 but should be similar .
I have heard of windows 10 updates installing the wrong drivers for GPUs and USB but haven't heard any about keyboard drivers but it is possible.


Here is a video for replacing the keyboard if needed
