Problems when you turn on the computer
These problems may occur when you turn on the power.
The computer will not start.
Make sure you attached the AC adapter and power cord/cable
properly or installed a charged battery.
Press and hold down the power button for a few seconds.
If you are using the AC adapter, check that the wall outlet is
working by plugging in another device, such as a lamp.
The computer starts but, when you press a key or move
the mouse, nothing happens.
You are probably in Stand By 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.
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” on page 260 .
The computer is not accessing the hard disk or the
external diskette drive.
Your computer normally loads the operating system from the
hard disk. If you have a hard disk problem, you will not be
able to start the computer. Insert a system diskette into the
external diskette drive and press
F12 when the machine starts,
then use the arrow keys to select the boot-up device.
