TP 380,385 - Hibernation does not complete
Applicable to: World-Wide
SYMPTOM:
The ThinkPad will not complete hibernation with a low battery.
CONFIGURATION:
Any ThinkPad 380, 385 with a low battery.
SOLUTION:
The 2635 battery technology will display fuel gauge readings of 100%, 80%, 10% and 0% during the discharge cycle and fuel gauge readings of 80% and 100% during the charge cycle. Because the fuel gauge starts at 80% during the charge cycle it is not possible to determine the percent of charge below 80%.
To ensure the battery charge is sufficient to allow completion of low battery hibernation the 2635 battery should be fully charged after a "Low Battery Hibernation" has occurred. You can do this by either replacing the low battery with a fully charged battery or attaching the AC Adapter to the ThinkPad and allow the battery to charge. A battery with a short (low) charge may not have enough battery power to ensure completion of hibernation. If hibernation does not complete the information in memory will be lost.
This is normal system operation. It is NOT a hardware failure.
NOTE: Low Battery Hibernation is not the normal default. It is an option that can be selected by the operator.
