Both CTRL keys are not working, I am unable to use the keyboard shortcuts. I thought it was something with the language setting, but I made sure it's set to English (USA). I also tested the onscreen keyboard and I am able to use the keyboard shortcuts, so I'm not sure if this is a software or hardware issue. I ordered a T5 screwdriver to open up the laptop and clean the keyboard, but I was wondering if you had any other insight on what may be wrong or anything else I can do. Thank you for any help you can provide!
