This tip is not software specific.
This tip is not option specific.
The following system BIOS or UEFI level(s) are affected:
- v1.11 (BuildID: D6E150D) or prior
Solution
This behavior is corrected in Unified Extensible Firmware Interface (UEFI) code v1.12 (BuildID: D6E153A).
The file is or will be available by selecting the appropriate Product name, Product machine type, and Operating system on IBM Support's Fix Central web page, at the following URL:
Additional information
The Advanced Configuration and Power Interface (ACPI) table for the network adapter in the UEFI code was incorrect. As a result, the power management tab is missing in the device manager.
This symptom has been fixed by updating UEFI code with a correct ACPI table.
