If the Notebook Has a Short Operating Time

Troubleshooting

If the Notebook Keeps Beeping

The notebook beeps repeatedly or displays a warning when battery power is low. Save your work, shut down Windows immediately, and insert a charged battery pack or plug in the AC adapter.

If the Battery Pack Does Not Charge

■Make sure the AC adapter is fully plugged into the power source and the notebook, and that the light on the adapter is on.

■If you are using a power strip, remove the AC adapter from the power strip and plug it directly into a wall outlet.

■Make sure the battery pack is fully installed and locked in place.

■Make sure you are using only the AC adapter included with your notebook (or other approved adapter that meets the power requirements of the notebook). Do not use a 60-watt, 3.16-amp adapter.

■Move the notebook away from any nearby heat source. Unplug the AC adapter and allow the battery pack to cool down. If the battery pack gets too hot, it will not charge properly.

■If available, try another battery pack and AC adapter.

If the Notebook Has a Short Operating Time

■Conserve power using any of the suggestions listed in the “Battery Packs and Power Management” chapter in this guide.

■If you are running an application that has an automatic save feature (such as Microsoft Word), disable this feature or increase the specified save time to reduce hard disk access.

■If the operating time has gradually become shorter and the battery pack is more than a year or two old, you may need to replace the battery pack.
