Symptoms

Scenario One: OOBE cannot turn the laptop off when it first runs

The OOBE cannot shut down the laptop after being run at when the laptop is turned on for the first time. The following products reboot back into the operating system instead.

Note: The issue is resolved and goes away after the laptop reboots.

Scenario Two: Pressing the Power Button does not work

There is no response on any of the following products pressing the power button to enter sleep, hibernate, or turn the laptop off.

When pressing power button

Note: This occurs when sleep, hibernate, or shut down has been set for the 'When I press the power button' power option in the control panel.

Affected Platforms:

  • Dell 15 DC15255
  • Dell Pro 15 Essential PV15255
  • Inspiron 15 3535
  • Vostro 14 3435
  • Vostro 15 3535

Affected Operating System:

  • Windows 10
  • Windows 11

Cause

There is a new variable update for the Advance Configuration and Power Interface (ACPI) Power Button Method (APBM) in the BIOS.

Scenario One:

However, the first shutdown becomes a reboot because the fixed register does not initialize properly. The shut-down (S5) command is misread as Reset.

Scenario Two:

However, the default value does not initialize the variable so it does not define the power button.

Resolution

Scenario Two Workarounds:

  • Configure the 'When I close the lid' power option to enter sleep, hibernate, or shut down instead.
    When closing lid 
  • Use the 'shut down or sign out' option in the start menu to select enter sleep, hibernate, or shut down instead.
