Power and battery problems
If the computer turns off immediately after it turns on
• Battery power is probably extremely low. Plug in the AC adapter or insert a newly
charged battery.
If the computer keeps beeping
• The computer beeps repeatedly or displays a warning when the battery is low. Save
your work, shut down the computer immediately, and insert a charged battery or plug
in the AC adapter.
If the battery doesn’t charge
• Make sure the AC adapter is plugged into the power source and that the light on the
adapter is on.
• If you're using a power strip, remove the AC adapter from the power strip and plug it
directly into a wall outlet.
• Make sure the battery is fully installed and locked in place.
• Turn off the computer, then make sure the battery contacts are clean and that the AC
adapter cables are fully plugged in.
• Move the computer away from any nearby heat source. Unplug the AC adapter and
allow the battery to cool down. An elevated battery temperature prevents charging.
• If another battery is available, try it.
• If another AC adapter is available, try it.
