These problems may occur when you turn on the power.

Make sure you attached the AC adaptor and power cord/cable 
properly or installed a charged battery.

Press and hold the power button for at least 10 seconds.

If you are using the AC adaptor, check that the wall outlet is 
working by plugging in another device, such as a lamp.

Verify that the computer is on by looking at the ON/OFF indicator. 
If the indicator is glowing, the computer is on. Also, try turning the 
computer off and then on.

If you are using an AC adaptor, verify that the computer is receiving 
power from the external power source by looking at the AC power 
light. If the indicator is glowing, the computer is connected to a live 
external power source.

Verify that the active program accepts text input. Try clicking your 
mouse on an area where you can type text and try typing again.

Your computer may be in Sleep mode and have a software or 
resource conflict. When this happens turning the power on returns 
you to the problem instead of restarting the system. To clear the 
condition, press 

Ctrl

, 

Alt

, and 

Del

 simultaneously. Then shut down the 

computer via software, or follow the steps if your program stops 
responding (see “Problems that are easy to fix” on page 48).

Clearing the condition may get the computer running, but it will not 
solve a resource conflict. Read the documentation that came with 
the conflicting device and “Resolving a hardware conflict” in your 
electronic user’s guide.

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 

any key, type the password and press 

Enter

. If no password is 

registered, press any key. The screen reactivates and allows you to 
continue working.
