Choose a symptom to begin troubleshooting
If you do not see your specific symptom please refer to Need more help.









































Battery does not charge.
Battery life (capacity) decreases with age and usage of battery.
Battery cannot be fully charged in standard charge time when powered off.
Battery discharges when system is unplugged and powered off.
System shuts down before or operates after battery status indicator shows empty.
System does not operate though the battery is fully charged.









Battery does not charge
Check the following:



  1. Is the AC adapter plugged into the wall outlet and connected to the ThinkPad? If not correct the problem and continue.

  2. Does the wall outlet have power? Some wall outlets are connected to a switch or the circuit may be open because of a blown fuse or circuit breaker.

  3. Does the AC adapter power the ThinkPad without the battery? If not the fault may be with the AC Adapter or the ThinkPad itself.

  4. Is the battery too hot? You cannot charge the battery when it is too hot. If the battery feels hot remove it from the computer and allow it to cool to room temperature. After it cools reinstall it and recharge the battery. If you still cannot charge the battery it will need to be serviced.

Battery life (capacity) decreases with age and usage of battery
Capacity is the length of time you can run your system on a fully charged battery. It is normal for all batteries to lose some capacity over time. Each time you discharge and recharge your battery you will lose a very small amount of this capacity.

Some of the capacity may be recovered through using a more aggressive power management scheme.

You may also want to check for specific information on your system; for example some BIOS updates include power management enhancements. Other systems have specific tools to help with battery life. To find drivers and files for your system go to ThinkPad software and device drive file matrix and select the link for your system.

Conditioning Nickel Metal Hydride (NiMH) batteries may improve their capacity but will not help Lithium Ion (Li-Ion) batteries. To condition NiMH batteries completely discharge them (also called a deep discharge) and recharge them every few months. Do not do this to Li-Ion batteries because it will actually damage them.
