Keyboard

Keyboard problems can be caused by your setup configuration. For more 

information refer to Chapter 5, 

 and Chapter 7, 

Check the Battery indicator. If it does not glow, 

let the computer charge the battery for at least 

20 minutes. If the Battery indicator glows after 

20 minutes, let the battery continue to charge at 

least another 20 minutes before turning on the 

computer. 
If the indicator still does not glow, the battery may 

be at the end of its operating life. Replace it. 
If you do not think the battery is at the end of its 

operating life, see your dealer.

If you frequently recharge a partially charged 

battery, the battery might not charge to its full 

potential. Fully discharge the battery, then try to 

charge it again. 

Check the power consumption settings in the 

Power Options. Consider using a power saving 

feature.

selected. Press Fn + F10 and try typing again.

Make sure the software you are using is not 

remapping the keyboard. Remapping involves 

reassigning the meaning of each key. Refer to 

your software’s documentation. 
If you are still unable to use the keyboard, 

consult your dealer.
