The amount of battery power consumed by your computer depends on such
conditions as the usage frequency, the operating temperature, and the period
in storage (if unused). The following tips can help you to extend the
life of your battery:
- If your battery is brand new and you are charging it for the first time,
it might not become fully charged due to the characteristics of the chemicals
in the cell. To maximize performance, ensure that all chemicals in the
battery are fully activated by cycling the battery (fully charge, then fully
discharge) three times. This procedure is also recommended if you
stored the battery for a few months.
- Do not charge the battery pack until all of its power is used.
Recharging a battery pack that is not completely discharged can shorten
battery life.
- Once you start charging the battery pack, do not use it until it is fully
charged.
- Whenever possible, use the ThinkPad battery power-saving modes:
- standby: The LCD and the hard disk drive are turned off.
- hibernation: All tasks are stopped. The memory data and the
current status of the computer are stored in the hard disk drive; then
the power is turned off.
- Decrease the LCD brightness.
- Stop the power supply to a serial device if it is not in use.
- Remove the battery pack and keep it in a cool place if you will not be
using the computer for a long period.
