If your Surface won’t turn on, won't wake up, or has a black screen without a Surface logo, you can try a few things to get it working again.
Disconnect accessories and make sure your Surface is charged
Things that you’ve connected to your Surface might be preventing it from turning on. Here’s how to check if that's the problem:
Disconnect any USB drives, SD cards, USB accessories, external monitors, docks, or anything else you’ve connected to your Surface. Then try turning it on—if that works, the accessory may be the problem.
If that didn't work, connect the power supply that came with your Surface.
When your Surface is plugged in with the original power cord, charge it for 15 minutes. Then press the power button to turn on your Surface. If the power connector light doesn’t turn on, or if it flashes, see Surface battery won’t charge or Surface won't run on battery.
Wake with keyboard and tablet shortcuts
If recharging your Surface didn’t wake it up, here’s a couple things to try.
Connect to a keyboard or use an integrated keyboard. Then press the Windows logo key + Ctrl + Shift + B.
If you're in tablet mode, quickly press the volume-up and volume-down buttons three times.
Force a shutdown
If charging your Surface and the keyboard or tablet shortcuts didn’t work, you can try to force a shutdown, and then restart. On most devices you can do this by pressing and holding the power button until the logo screen appears (about 20 seconds).

If your Surface still won’t turn on
If none of these steps resolve the problem, you can submit a service request to Microsoft.
