症狀

"Warning: The AC adapter and battery must be plugged in before the Dock Firmware can be updated. Press OK when they are both plugged in or CANCEL to quit" occurs during a dock firmware update.
Warning message seen during dock firmware update

Affected Platforms:

  • Dell Thunderbolt Dock - WD19TBS
  • Dell Thunderbolt Dock - WD22TB4
  • OptiPlex 3090 Ultra
  • OptiPlex 7090 Ultra

原因

Dell Firmware Update (DFU) version 5 removed support for System Management BIOS (SMBIOS). As a result, computers without a battery installed may be incorrectly detected, because the firmware can no longer read accurate hardware information from SMBIOS.

解析度

Note: Before starting the update, perform the following:
  • Back up all personal data. For more information, refer to Back Up and Recovery.
  • Connect the AC adapter.

Updating the Dell Dock WD19/WD22TB4 Firmware Update Utility to version 01.01.01.01,01.01.11.01 or later on the dock resolves the issue. To download and install the firmware, refer to the Driver Update Guide.
