Update the Surface app to version 74.8150.129.0 or later, restart Windows once, and then reopen Surface app → Battery & charging → Smart charging → Charge to 100%; this replacement build is the reported fix for the October 28 disappearance of the battery controls.^1^ ^2^
Install and verify the corrected build
Since repair, reset, reinstall, and ordinary restarts have already failed, do not repeat them.
- Open Microsoft Store.
- Select Library → Get updates.
- Install any available update for Surface.
- Open Settings → Apps → Installed apps → Surface → Advanced options and check the displayed version.
- Confirm it is 74.8150.129.0 or later.
- Restart Windows to complete installation of the new build.
- Open Surface → Battery & charging → Smart charging → Charge to 100%.
- Keep the Surface connected to power for several hours before traveling. Microsoft specifically recommends selecting the override several hours before it is needed.^3^
Surface Laptop 6 for Business supports Battery Smart Charging and the related charging controls, so the entire Battery & charging section disappearing is not an expected model limitation.^4^
Microsoft Store does not provide a normal user-facing method to select an older Surface app release. Installing the corrected current build is preferable to obtaining an old package from an unofficial source.
Immediate travel fallback
If Microsoft Store has not yet offered version 74.8150.129.0 and the flight is approaching:
- Disconnect the charger and use the Surface until the battery falls below 20%.
- Reconnect the original Surface power supply.
- Leave it charging.
Surface Smart Charging automatically pauses after the battery has discharged below 20%, allowing it to charge to 100%; it can enable itself again later according to usage patterns.^1^
This is the documented automatic fallback, although deliberately discharging the battery is less convenient than using Charge to 100%.
If the corrected build still has no battery section
- In Surface → Help & support, check the update status and install any offered Surface driver or firmware updates through Windows Update. If this is an organization-managed Surface Laptop 6 for Business, contact the IT administrator because Surface updates may be deployed internally.^4^
- If the app is already at or above 74.8150.129.0, Windows and Surface firmware are current, and the section remains absent, report the app version, Windows build, and device model through Surface → Help & support → Get help. The Surface app can detect device issues and route the case for support.^5^
Do not enable or change the UEFI Battery Limit setting as a workaround: that is a separate kiosk-style feature that limits charging to 50%, not a method for forcing a full charge.
