The number pad on my acer laptop is out of wack. My toddlers got a hold my computer and must have changed a setting. Some of the numbers work...but when I press the 8...the screen reloads and erases part of the number sequence I already punched in. Also, the 6 above the letters does something similar. How do I reset the number pad so that I can use it?
The keyboard is damaged then, or the ribbon cable below the keyboard sending the keypresses into the notebook is a bit loosened.
What model is the Aspire exactly, there are over 30+ models?
Keyboards in laptops are extremely easy to replace and cheap. I would first check the connection (ribbon) then order a new one if that doesn't help. Any simple youtube video can show you where to take the screws out etc to replace them.
