Information
Battery Discharge and Step Charge For Libretto that have a POWER PROBLEM:

"EXAMPLES ARE: Stuck in a Hibernation Mode, Clocks not keeping the correct time, Systems that will not boot, ETC..."

1. Unplug the computer from the AC adapter and turn it on. Let the computer run under battery power until the computer turns off,
which is about 16 hours, indicating that the battery is fully discharged.
2. Remove the battery pack.
3. Let the Libretto unit discharge the internal batteries for a period of 12 hours.
4. Using a soft cloth, wipe off the battery packs connectors and the AC adapters connectors.
5. Plug the computer into the AC adapter and check the wall outlet, making sure the connection is firm.
6. Now test the Libretto unit, by turning it on. If the Libretto works then proceed with the following, if not then call Toshiba.

  • Now download and flash the Libretto's BIOS with the latest version. "Do this even if it already has been done before."
  • Re-insert the battery pack.
  • With the Libretto Unit turned off, let the batteries charge until the status light or icon glows green.
  • Unplug the AC adapter.
  • Remove the battery.
  • Wait 90 seconds and re-insert the battery.
  • Plug the AC adapter back in.
  • Let the battery recharge until the battery status light turns green or the icon displays 100%.
  • Now your battery should be fully charged. Unplug the computer from the AC wall outlet and turn on the Libretto.
  • You should notice that the unit will not be locked in a hibernation mode, and that you have a longer battery life and stronger boot-up.
  • All batteries hold less charge as they age. Over time, if you attempt to charge a battery and the battery indicator does not show a full charge, you may need to purchase a new battery.
