turned on. Make sure the power indicator shows the power is on. See
“Turning On Your Computer” on page 26 for more information.
❑ Make sure the battery is inserted properly and is charged.
❑ If the floppy disk drive is installed in the multipurpose bay, make sure it is
empty.
❑ If the computer is plugged into a power strip or Uninterruptible Power
Supply (UPS), make sure the power strip or UPS is turned on and working.
❑ If you are using an external display, make sure it is plugged into a power
source and turned on. Make sure the brightness and contrast controls are
adjusted correctly. See the manual that came with your display for details.

adapter and reinsert the battery, and turn on the power.
