I am running a Surface Pro 8 with windows 11 OS. I go to the UEFI interface when starting up and to the boot options screen. I try to move the switch for battery limiting and it simply moves back to the off position after toggled. It will not stay in the on position.

    Hello

    Welcome to the Microsoft Community.

    Based on your description of the battery limiting switch reverting to "Off" in the UEFI interface on your Surface Pro 8, here’s a structured troubleshooting approach combining firmware, software, and hardware solutions:

    1. Force UEFI Reset & Retry Toggle
    • Hard reset the device: Hold the power button + Volume Up for 30 seconds until the screen flashes and the device restarts. This clears temporary firmware glitches.
    • Re-enter UEFI: Immediately after reset, press and hold Volume Up while tapping the power button. Release when the UEFI screen appears.
    • Retry the toggle: Navigate to Boot Configuration > Battery Limit and toggle it again. If it still reverts, proceed below.
    1. Update UEFI/Surface Firmware

    Outdated firmware often causes UEFI settings instability:

    • Windows Update method:
      • Go to Settings > Windows Update > Advanced Options > Optional Updates.
      • Install all Surface UEFI and System Firmware updates.
    • Manual firmware recovery:
    1. Power Flush & Battery Calibration

    Electrical residue can interfere with settings:

    • Shut down the Surface and unplug all peripherals.
    • Hold Power + Volume Down for 40 seconds.
    • Release, wait 5 minutes, then power on normally.
    1. System Reset as Last Resort

    If firmware updates fail, reset Windows while preserving UEFI:

    • Soft reset (keeps files):
      • Settings > System > Recovery > Reset this PC > Keep my files.
    • USB recovery drive method:
      • Create a recovery USB via another PC using the Surface Recovery Image.
      • Boot from USB (Volume Down + Power), then choose Troubleshoot > Reset.
    1. Hardware Checks & Service
    • Battery health check:
      • Run powercfg /batteryreport in Command Prompt. If "Design Capacity" is significantly below "Full Charge Capacity", the battery may need replacement.
    • Contact Microsoft Support:
      • If all steps fail, the UEFI chip or battery controller may be faulty. Surface Pro 8 has a 2-year limited warranty—request firmware-level diagnostics.
    • Surface UEFI is proprietary; generic BIOS utilities may cause instability.
    • Ensure the Surface is plugged in during UEFI changes to prevent voltage drops.
    • Before system resets, backup data via OneDrive or external storage.

    If you have any updates, feel free to let me know.

    Best Regards,
