Check the power options using the Power Management utility. 
Have you added a device, such as a PC Card or memory module, 
that takes its power from the battery? Is your software using the 
hard disk more? Is the display power set to turn off automatically? 
Was the battery fully charged to begin with? All these conditions 
affect how long the charge lasts.

If, when you type, strange things happen or nothing happens, the 
problem may be related to the keyboard itself.

A keypad overlay may be on. If the numeric keypad or cursor 
control light is on, press 

Fn

 and 

F10

 simultaneously to turn off the 

cursor control light or press 

Fn

 and 

F11

 simultaneously to turn off 

the numeric keypad light.

If the problem occurs when both the keypad overlays are off, make 
sure the software you are using is not remapping the keyboard. 
Refer to the software’s documentation and check that the program 
does not assign different meanings to any of the keys.

If you have a second keyboard, try it. If it works, the first keyboard 
may be defective or incompatible with your computer.

Here are some typical display problems and their solutions:

Display Auto Off may have gone into effect. Press any key to 
activate the screen.

You may have activated the instant password feature by pressing 

Fn

and

F1 

simultaneously. If you have registered a password, press
