Microsoft Surface Tablet Not Charging

The convenience of a portable device is that you aren't tethered to an outlet. This does mean that you have to give your device some juice once in a while. But if you can't get it to take a charge, it's no different than any wired device. Don't settle for a corded tablet.

Before undertaking any of the more time-consuming solutions below, here are a few fundamentals to get you started.

Check the light on the charger. If there is no light, flip the charger 180 degrees. It may work in one direction, but not the other. Skip through to Faulty Power Source if you have no light.
Force a restart. This may clear minor system errors. Be sure to use the proper procedure for your model.
- For the Surface Pro 5 and newer, plus all models of Surface Go, press and hold Power for 20 seconds to force a shutdown and subsequent boot.
- On the Surface Pro 4 and earlier, press and hold Volume Up and Power for about 15 seconds. Wait a few seconds, then power on again as usual.
Remove all accessories and peripherals. They can interfere with the charger. making proper contact.
Is your battery detected by Windows? If no, remove the charger when your Surface is on. Does it stay on without the charger connected? Immediate shutdown points to a battery issue.

Surface devices have long featured a proprietary charger type. It's conveniently compatible with most Surfaces—even the Surface Book and Surface laptop use it.

Check the light on the charger. It should be lit when connected to the device. If it is not, try a different charger.
Use an Authentic Microsoft charger if possible. Third party chargers for Microsoft devices are notoriously troublesome.
Verify the outlet the charger is plugged into is providing power. Connect a known good device and see if it powers on.
If your Surface has a USB C port, try to use that to charge. Be sure the wattage of your charger is at least equal to the original charger.

Like all mobile devices, the charge port is especially susceptible to damage and wear. It more exposed than the rest of the tablet's circuitry. Crevices in a device will always attract things you don't want them to.

Verify the port is clean. Does a charger sit flush against the edge of the shell? The port may be clogged if it sits at an angle or has a loose fit. Use a flashlight to inspect.
- Remove anything caught in the port. Use compressed air and a toothpick to avoid damage. Other non-conductive tools can be used in place of a toothpick, but avoid inserting anything metal.
- Isopropyl alcohol and a cotton swab can be used to get rid of persistent grime.
- Once the debris has been removed, give charging another go.
Check for signs of damage or burn. A bad charger can also damage the port, or the board.
Pay attention to charging light behavior. The light will come on when the Surface recognizes it is connected.

Batteries are nefarious. They fail often, due to their "consumable" nature, but not always in predictable ways. Although they typically die slowly and with diminishing power on time, a bunk battery could fail suddenly, or may not be recognized by the system.

Check for visual signs of battery swelling. This may manifest as areas of discoloration on the display (swelling exerts pressure on the display from the inside). The display may also bow outward, or separate from the housing.
Internal signs of battery age or failure could include leaking or lumpy battery cells.

The motherboard is the hub for most of a Surface’s functionality. Any of the small components on the board may have failed or become damaged. Motherboard fault is a safe assumption of cause if nothing else on this page has worked.

Check for signs of a board issue - burned or cracked components, liquid residue, corrosion, or bend. If there are signs of liquid, there’s still hope your Surface can be resurrected.
Replacing the motherboard is often the most practical solution for a DIYer whose board has failed.
Board repair is possible, but requires skills in microsoldering and board diagnostics. It is an art unto itself, but a worthy endeavor. If you’re curious and want to know more about getting into micro soldering, here’s some good reading and some good watching to get you started.
