I have a Dell Inspiron 1750 Laptop, recently certain keys on my keyboard started not working the b,n,? the 1 and down arrow keys, so I thought it was the keyboard and ordered a new one and changed it well I still have the same keys not working. I also reinstalled the keyboard drivers. and when I plug in a usb keyboard everything works fine. CAN ANYONE HELP ME PLEASE
This sounds like a motherboard issue, but you could try reinstalling Windows before replacing it.
Thanks man that's what I figured but was trying to see If anyone else had the same problem and maybe there was a software fix for it, I tried a fresh install no luck. Good thing its not my computer just trying to help out a family member that knows nothing about computers.
