TP 755CX - 9545 Li-Ion Battery Information
Applicable to: World-Wide
Symptom:
The following Tip is applicable to 755CX and other 755 models using a Li-Ion (Lithium Ion) main battery FRU P/N29H9232.
The system:
1. fails to power up using the battery.
2. will power up using the AC Adapter.
3. will fail to charge the battery during a normal charge cycle with the system off.
4. will not charge at all while it is powered on.
Problem Isolation Guidance:
1. The battery fuel icon shows the battery as a dashed line instead of a solid out line.
2. The charge indicator will blink during the charge cycle when the system is turned off.
Cause:
The Li-Ion battery was completely discharged for an extended period of time due to use or new battery shelf life. Follow the recovery procedure in FIX section to correct this condition and obtain full battery potential.
Fix:
The battery must be charged for a minimum of eight (8) hours. This can be done in the system while it is off or with the external battery charger. To ensure this does not occur again, recharge the main battery when the system indicates a charge is needed. The Li-Ion battery can be recharged at any time during the normal discharge cycle and obtain a full charge - they do not have to be completely dis-charged before recharging. Once the battery is charged it can be stored for extended periods of time (up to a year) without incurring this condition. This condition will not effect the life of the battery.
