Installation & Handling Guide
- Precision Installation: This is an internal battery. Due to the ultra-thin magnesium chassis of the Notebook 9, please use a precision screwdriver and handle the bottom panel with care to avoid bending the light-weight alloy.
- Connector Alignment: The 7.7V system requires a perfect electrical contact. Ensure the battery’s multi-pin plug is pushed straight into the motherboard socket. Do not apply force at an angle.
- Optimization: For new polymer cells, it is recommended to perform 2-3 cycles of charging to 100% and discharging to 10% to ensure the OS accurately calculates the remaining runtime.
Frequently Asked Questions
Q: Does this battery fit the regular Notebook 9 13-inch (900X3L)?
A: No. The standard 900X3L (13-inch non-spin) uses a smaller 30Wh battery (AA-PBUN2TP). This AA-PBUN4AR is exclusively for the 940X3L Spin and the 15-inch 900X5L.
Q: Is the color of the battery casing important?
A: This unit comes in the standard white/light-grey casing as per original specifications. Since it is an internal battery, the color will not be visible once the laptop is reassembled.
