Q: How do I recalibrate the battery on this notebook?

A: If the computer unexpectedly goes into Standby mode while you are using it, but the battery charge is not low, you may need to recalibrate the battery. You should also recalibrate the battery periodically to maintain the accuracy of the battery gauge.

Note: Do not use your notebook during the recalibration process. If recalibration is interrupted, you must start the process over again.

Follow these steps to recalibrate the battery using the BIOS Setup Utility.

  1. Connect the AC adapter and then turn on the notebook.

  2. As the notebook starts, at the Gateway logo screen, repeatedly press the F2 key until you enter the BIOS Setup Utility.

  3. In the BIOS Setup Utility, use the TAB key to select the Advanced menu.

  4. On the Advanced menu, select Battery Auto Learning, and then press the SPACEBAR to select Enabled.

  5. Use the RIGHT ARROW key to select the Exit menu. On the Exit menu select Exit Saving Changes, and then press ENTER.

  6. At the Setup Confirmation prompt, select Yes, and then press ENTER.

  7. The battery recalibration process begins and a screen opens showing you the progress. The entire process takes several hours.

  8. When the recalibration has finished, and the message "Press [Esc] key to exit" appears, press Esc. The battery charge indicator now displays an accurate battery charge.
