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 charged
battery.
If the computer keeps beeping
• The computer beeps for 15 seconds when battery power is low. Save your work, shut
down Windows immediately, and insert a charged battery or plug in the ac adapter.
If the battery doesn’t charge
• Make sure the ac adapter is fully plugged into the power source and the computer, 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.
• Move the computer away from any nearby heat source. Unplug the ac adapter and
allow the battery to cool down. If the battery gets too hot, it will not charge properly.
• If available, try another battery and ac adapter.
