System Board (Motherboard)
The UEFI/BIOS firmware is stored on a non-volatile SPI Flash chip soldered to the main logic board. A failed update typically results from a corruption of the boot block or an incomplete write to the firmware sectors, which, due to the lack of a socketed BIOS chip, necessitates a full motherboard replacement to restore system functionality.

CMOS Battery
Invalid or corrupt NVRAM data can prevent the BIOS Update Utility from correctly identifying the current firmware version or hardware state. Replacing the coin cell battery and discharging the capacitors forces a reset of the CMOS settings, potentially clearing the software flags that caused the installation failure.

Rechargeable Li-Polymer Battery
Lenovo firmware update utilities contain a hardcoded safety check requiring a specific battery charge percentage and health status. If the battery exhibits high internal resistance or fails to report a steady voltage, the BIOS installer will trigger a 'Failed' status as a protective measure to prevent the system from losing power during the critical flashing process.
