Hi Alice Hughes,
I can understand how this frustrating when this happened just before your flight, especially after you already reset, repaired, reinstalled, and restarted the Surface app without getting the Battery & charging section back.
Since your Surface app is already on version 76.10212.108.0, I would not recommend trying to obtain the older app version mentioned in the previous response. Microsoft Store does not normally provide an option to roll the Surface app back, and installing an older package from an unofficial source could create additional security or compatibility issues.
At this point, the missing battery section appears to require further investigation rather than repeating the same app troubleshooting. Because this is a Surface Laptop 6 for Business, please contact your organization’s IT administrator first, as the device or its charging settings may be managed by your organization. If the device is not centrally managed, contact Surface Support and provide the device model, Windows build, Surface app version 76.10212.108.0, and the date when the battery controls disappeared. This will allow the support team to check the device configuration and document the issue with the current Surface app build.
Please note that this is a user-to-user support forum. Forum contributors cannot roll back Store apps, change Smart Charging from the back end, or release an application update. I’m sorry there is not a reliable forum-side fix I can offer before your trip, but reporting the exact app version and missing section directly to Surface Support is the safest next step. Thank you so much for your understanding.
