Your Surface doesn’t recognize your Power Cover
Solution 1: Check the charge on your Surface
To detect your Power Cover and draw power from it, your Surface needs to have a partial charge. Here’s how to check if your Surface has enough charge to recognize your Power Cover.
- Remove the Power Cover from your Surface.
Select the battery icon in the taskbar.
- If the charge is 10 percent or less, connect the power cord to the charging port on your Surface and plug it into an electrical outlet to charge your Surface. You can connect the Power Cover while your Surface is charging.
If your Surface still doesn’t recognize your Power Cover, try Solution 2.
Solution 2: Check the physical connections
If your Power Cover can’t connect to your Surface, or if it connects but your Surface doesn’t recognize it as a second battery, check the physical connections.
- Remove the Power Cover from your Surface.
- Make sure the magnetic connectors on your Surface and Power Cover are clean and free of damage. With the power supply unplugged from the electrical outlet, clean the connectors on your Surface and Power Cover with a soft cloth and a small amount of rubbing alcohol.
For more info, see Clean and care for Surface.

Power Cover won’t take a charge or won’t charge your Surface
In order for your Power Cover to take a charge, it must be attached to a Surface Pro or Surface Pro 2 that is connected to a power source using the power cord and the charging port and that is turned on (it can be in sleep mode).
When your Surface is 80 percent charged, it starts charging the Power Cover. When the Power Cover is 80 percent charged, your Surface finishes charging. When your Surface is fully charged, the Power Cover finishes charging.
How the batteries charge.
How quickly your Power Cover charges depends on how much charge your Surface has and how you’re using it at the time.
Your Surface must have at least a partial charge—about 10 percent—in order to draw power from your Power Cover.
Solution 1: Check both battery levels
- Make sure that you have good connections between your Power Cover and Surface, between the Surface charging port and the power connector, and between the power cord and the power source.
- Select the battery icon in the taskbar. It should include the plug icon .
If you don’t see the plug icon, try the troubleshooting solutions in Surface battery won’t charge.
The icon shows a weighted average of the Surface and Power Cover batteries. To see how much charge is in each battery, select the battery icon.
- If the Power Cover battery is more than 80 percent charged and the Surface battery is less than 100 percent charged, check again later. Your Power Cover won’t charge above 80 percent until your Surface is 100 percent charged.
- If the Surface battery is less than 80 percent charged, check again later. Your Power Cover won’t charge until your Surface is 80 percent charged.
- If the Surface battery is more than 80 percent charged and the Power Cover battery is less than 20 percent charged, continue with Step 3.
- If the Power Cover battery isn’t listed, continue with Step 3.
- Check the physical connection as described above under Surface doesn’t recognize Power Cover.
