Mesa battery firmware update 2

26 Aug 2013

The Battery Firmware Update allows the Mesa to better track the percent charge remaining (time to empty / full) of the inserted battery pack(s) over an extensive period of time. It may also fix and prevent a Mesa from not detecting / charging an inserted battery pack (most often just a second battery, or in other words a battery in the top slot 2). This can be installed again as needed to fix such issues. See below for install instructions.

WARNING: If a previous version has not been installed, then this installer may take up to 20-30 minutes to complete. The Mesa needs to remain attached to a stable power source (recommended to use an Uninterruptible Power Supply (UPS)) for the duration of the install process. Power failure during install may require that the unit be submitted to a repair center for servicing.


Install Instructions -

  1. Click on the link below to download.
  2. Save the “Mesa-Battery-Update-2.CAB” file (do not extract) to a location on your desktop PC.
  3. Copy the file to a location on the Mesa. Attach the Mesa unit to a stable power source (such as a UPS).
  4. Remove both battery packs from the Mesa.
  5. Locate the file in File Explorer on the Mesa.
  6. Tap on the file to execute the install (which will automatically reset the unit).
  7. Wait for the installer to complete performing the update.
  8. Suspend the unit.
  9. Install two battery packs with the wall charger still inserted.
  10. Wait for the Mesa red power/charge LED to start flashing (this should take 15 to 30 seconds). This confirms the update was successful. For further validation, tap on Start > Settings > System > System Information > System ID, and confirm that the "Pic Version" is now 3.2.5.
