I have a problem in my laptop(actually, MANY of them). I can't type some letters in my keyboard. Like D, backspace, ; ,0, / , ETC. Sometimes i have to press it really hard until it types. I fixed it by punching my laptop's bottom, it usually fixes it. But for some time. After one hour, my laptop's can't type those letters again. Help?
Hope to see some good news!
This could be a defective keyboard. It could also be a loose connection at either end of the cable that runs from the keyboard to the main board. How hard it is to get to that cable varies from laptop to laptop. If you somewhat technical, you can try lifting the keyboard, and checking the cable. If you can get to the cable, disconnect and reconnect each end. If that doesn't work, it's time to find someone with considerable experience to work on the laptop. They will probably try replacing the keyboard.
