3. Watch the CPU Usage. It is okay if the processor usage is occasionally 100 percent, but if it is 100 percent

most of the time, this may indicate a problem.

What to do if applications are keeping the CPU busy

If possible, close applications that keep the CPU busy when you are not using them

For information on calibrating the battery, refer to Battery Calibration.

Tip 4. Get a good charge

Your computer will charge more quickly if it is turned off or suspended

In warmer or cooler temperatures, your battery can take much longer to fully charge

If your battery is charged in a cold (less than 41°F/5°C) or very warm (greater than 122°F/50°C) environment,
