You’re working on your laptop, and all of a sudden, the “I” key stops working. Or maybe a whole section of keys is taking forever to respond. Worse yet, the keyboard cuts out entirely. While this can be a hassle, particularly when you have work due, there are a few things you can try yourself to get back to the job at hand.
Before you attempt random fixes, try to narrow down your problem: is there something wrong with the keyboard hardware itself, or is a software glitch preventing Windows from recognizing keystrokes? Figuring this out can save you a lot of time later on.
Reboot your computer and try to enter the UEFI or BIOS—usually by pressing “Delete,” “Esc,” or some other key as your computer boots. (It will tell you which key to press along the bottom of the screen.) If you’re unable to enter the BIOS and navigate it with your keyboard, there’s a good chance you’re dealing with a hardware problem. If you can enter the BIOS, and the problem key(s) work fine within that menu, your problem lies within Windows itself.
