Hi Ella Moran,
Thank you for reaching Microsoft Community. We're sorry for the inconvenience this has caused you. Allow me to ask few questions to help us further isolate the issue.
May I know if the LED light on the power connector turns on when the charger is plugged in?
When did this issue started?
What version of Windows are you on?
Will you check the battery status on taskbar? Is it showing its charging or showing plugged in, not charging?
If the battery icon shows a power plug on the taskbar, but when you select it, you see Plugged in, not charging, then Surface detects the power supply but is not charging the battery.
We recommend trying the following steps below.
Force a restart.
Press and hold the power button until the logo screen appears (about 20 seconds). See Force a shut down and restart your Surface for more info.
Remove the battery driver and install updates.
- Plug in your Surface.
- Select Search on the taskbar, enter device manager, and then select Device Manager from the list of results.
- Select the arrow next to the Batteries category.
- Double-tap or double-click Microsoft Surface ACPI-Compliant Control Method Battery or Surface Battery, select the Driver tab, and select Uninstall Device > OK.
- Select the computer at the top of all the categories, select the Action menu, and then select Scan for hardware changes.
- Leave your Surface plugged in and install Surface and Windows updates, see Download drivers and firmware for Surface for details.
The following troubleshooting guide can be found at Surface battery won’t charge or Surface won’t run on battery - Microsoft Support.
This article What to do if your Surface power supply or charger doesn’t work - Microsoft Support may also be useful to you as well.
Let me know how it goes.
Kind regards,
