Hi Mycsatx,
Try to change the keyboard settings:
Click on Start -> Control Panel -> Ease of Access -> Ease of Access Center -> Make the keyboard easier to use and uncheck all the options. Click on ‘Apply’ -> Ok. Restart the computer and check.
Alternatively, check the on screen keyboard:
- Press and hold the Windows key and press 'R' key. This will open the run window
- Type 'OSK' without the parenthesis, click on 'Ok'
- Use the on-screen keyboard and check if you face the same issue (use the mouse/touchpad to use the on screen keyboard)
If the above steps do not work, then check in Safe mode:
- Power off the computer
- Restart the computer, tap F8 on Dell logo 2-3 times
- This will take you to ‘Windows Advanced Boot Options’
- Choose ‘Safe Mode’ in the Advanced Boot menu (use ‘up’ or ‘down’ arrow keys to highlight the option, press ‘enter’ to select)
- When Windows finishes loading in Safe mode, check if the keyboard responds properly
If the issue persists, please reply with the operating system installed on your computer and the exact system model.
Hope this helps.
