Battery Problems
If you have trouble running the computer from the battery pack,
follow the steps in this section to find the problem. (Be sure to read
Chapter 3 for information on the battery.)
1. Check the low battery light. If it is blinking, the battery is low
and you need to recharge it. See Chapter 3 for instructions.
2. If you think the battery is not providing any power, it may not
be installed properly. Try removing and reinstalling it,
according to the instructions in Chapter 3. Make sure the
battery cover is closed securely.
3. If you have a second battery that is fully charged, use it to
replace the one in the computer. If you replace the battery
pack and the computer works properly, then you need to
recharge the other battery.
4. If you replace the battery pack and the computer does not work
properly, the new battery may not be fully charged. Recharge
this battery until it reaches its maximum capacity.
5. If the power light still does not come on, connect the AC
adapter to the computer and plug the adapter into an electrical
outlet. Turn on the computer and see if it works using the AC
adapter.
If the computer works using the AC adapter, you may need
to check your battery pack. If the computer does not work
with the AC adapter, see “AC Adapter Problems.”
6. If you have not used a battery in a long time (three months
or more), you may need to recharge it.
7. If you find that over time the battery is losing its charge in
less and less time, it may be reaching the end of its life. You
may need to replace it with a new battery pack.
