Symptoms of battery failure.

When a BIOS battery fails, the BIOS settings will not be retained if the AIO loses power. Sometimes battery failure can occur prior to the issue becoming apparent. It is recommended that these are periodically replaced by our clients, as part of their IT hardware maintenance schedule/s.

Typically after a power cut/outage or unplugging the AIO (e.g. to move it) the below Windows BSOD error appears:

 

This is because the 'Chipset SATA Mode' has changed back to it's default setting of AHCI. It needs to be set to IDE. If you need to revive your AIO unit immediately, please follow the steps in this article under Resolving SATA Controller Issues.

4. Disconnect the fingerprint module (gently) and set aside for re-installation later.

5. With the unit facing down, lift the bottom gently and slide the back of the AIO off the screen bezel. Take extra precaution as the screen connectors will remain connected throughout this process, and we do not want to disconnect/damage these.

6. Locate the battery on the motherboard, and replace as per manufacturers specifications. These typically include (non-exhasutive list):

  • Usage of an anti static strap.
  • Replace battery with exact same unit/specification.
