If your Microsoft charger is not working, you can fix it by checking the power cables and the power supply unit. Disconnect all cables and any USB accessories. Unplug the Surface from its power source. Let everything rest without power for at least 10 seconds.

It can be extremely frustrating when you go to use your Microsoft Surface and it has no charge. There are a variety of reasons why this is happening. This article will help you troubleshoot the problem and get you back to using your Surface again.

Microsoft Surface Charger Light Blinking

You connect your Surface to the charger and the LED light indicator turns on to let you know the Surface is charging. But what does it mean when the Microsoft Surface charger light is blinking?

If your Microsoft Surface charger light is blinking, disconnect the power connector from the Surface. Inspect the power cable for any signs of visible damage. Connect the charger to another power source or surge protector.

In rare cases, the blinking light could signal a hardware issue or a faulty connection between the charging cable and power supply. Opening the Surface will void any warranty you have and it could also result in damaging the Surface.

If you feel the charger is not working because of a faulty power supply connection or other hardware issues, it is best to take your Surface to a Microsoft professional to diagnose and repair the issue.

Everything is connected. The power cord is connected to a working outlet, but your Surface is still not charging. What can you do if your Microsoft Surface charger is not charging?

If your Microsoft Surface charger is not charging, the Surface may be behind in recent updates. You can run a self-diagnostic with the Windows Update troubleshooter. Go to Start > Settings > System > Troubleshoot > Other Troubleshooters > Windows Update > Run.

Updates are what keep our electronics running with the most current software. Updates also provide the latest and best protection available.

Often overlooked are the individual updates for drivers. Drivers are how the hardware and the Surface’s operating system communicate with each other. Each piece of hardware has a specific driver.

When a driver is outdated, that specific hardware will not work correctly. It may even stop working altogether. The following steps will walk you through how to remove the current battery driver and install the updated version.

Step 1: Connect your Surface to the charger.

Step 2: In the search bar enter Device Manager.

Step 3: Select Device Manager.

Step 4: Select Batteries.

Step 5: Select Surface Battery.

Step 6: Go to the Driver tab.

Step 7: Select Uninstall Device.

Step 8: Select OK.

Step 9: Select your computer from the list of categories.

Step 10: Select Action.

Step 11: Select Scan for hardware changes.

Step 12: Restart the Surface to apply the new driver updates.

Microsoft Surface Charger Making Noise

Red tablet PC

You hear a buzzing or humming noise and realize it’s coming from the Surface charger. What does it mean when the Surface charger is making noise?

Microsoft Surface charger making noise could signal a problem with the power cable and connectors. Unplug the connectors and inspect them for signs of damage. Rotate the power brick 180 degrees and then plug it back in.

All chargers make some noise. The noise is usually such a low frequency that we don’t notice it. If your Surface charger is making noise that seems exceptionally loud, there is an issue with either the battery brick or the power cord.

Sometimes the buzzing sound means the Surface is straining too much. When the computer’s processing unit is under strain, the fan has to rotate faster, creating a buzzing sound.

You can adjust the Surface’s performance by clicking on the battery icon in the taskbar and adjusting the power mode to ‘Best Performance’.

Microsoft Surface Charger Not Lighting Up

When you connect your Surface to the charger, the LED indicator light illuminates to let you know it’s charging. What does it mean when the Surface charger is not lighting up?

If your Microsoft Surface charger is not lighting up, the power supply may be bad, the power cable may have been damaged, or it is not connected properly. Clean the charger components if they are dirty. Make sure the outlet in use is receiving sufficient power.

The Surface battery will not charge if the charger connector has damage. The connector for Surface is a flat, magnetic charger that is inserted with connectors. If the connectors are damaged, the battery will not receive power and the Surface will not charge.

Outlet Test

The Surface charger relies on a working outlet to charge the Surface. If the outlet is not receiving sufficient electricity, the charger will not charge.

A multi-meter tool will let you know if the outlet is receiving electricity but not everyone has this tool. If you are one of those people, you can do an outlet test with a lamp.

Plug a small appliance such as a lamp into the same outlet as the Surface charger. If the lamp turns on, the outlet is working. If the lamp does not turn on, there is an electrical issue with the outlet and a qualified electrician needs to inspect the outlet further.

USB Port

Another way to test the charger is using the USB port. Connect a device to the USB port. If the device does not turn on, this means the Surface charger is bad and needs to be replaced.

Rotate Charger Connector

Surfaces have a unique charger. Unlike traditional laptops, Surface laptops have a flat magnetic charger that can be connected in two different ways.

Sometimes rotating the charger in the Surface port will resolve the issue. Cleaning the contacts with a lint-free cloth will improve the connection. If the connector is bent or damaged in some way, it needs to be replaced.

Microsoft Surface Charger Gets Hot

The charger that came with your Surface works. Your Surface has a full battery but the charger is hot. Why does the Surface charger get hot?

If your Microsoft Surface charger gets hot, unplug the charger and let it rest until it cools down. Plug the charger into another power source. Do not use the Surface while it is charging. Only use the charging cable that came with the Surface.

It is normal for the charger to feel warm, at the very least. The charger is taking anywhere from 110-120 volts from the wall outlet and is converting it to around 5 or 10 volts. This is a lot of work for that little battery brick.

While it’s normal to feel a little warmth from the charger, excessive heat is a serious problem. The buildup of heat can cause an electrical fire.

One reason why the charger gets hot is if there is an electrical current problem. Plug a smaller appliance into the same outlet, such as a lamp, and see if the power cord gets hot. If it does, contact an electrician to inspect the outlet right away.

Inspect the charging cord pins for any signs of damage or buildup. If the pins become stuck, this can cause the electricity to be drawn into the charger on the watt-side only.

Leaving the charger connected for extended periods of time can also cause the charger to become hot. This will cause the battery to overheat and will eventually kill the battery.

Microsoft Surface Charger Buzzing

latest Microsoft table on the table

When our electronics are connected to a power source, the electronic device has to work to convert the power it receives into a lower voltage while also increasing the current. That’s a lot of work for a little charger.

The charger will make a buzzing sound when it’s hard at work. A slight buzzing sound is normal for all electronics. However, if the buzzing sound is so loud it’s disruptive, that means there is a bigger problem.


Inspect the charger for any signs of visible damage. If the buzzing sound started suddenly, the charger most likely experienced some stress or damage.

If the charger has signs of damage, even slight damage such as a dent, the charger needs to be replaced. It may be tempting to buy a cheaper version online of the Surface battery but this is not an area where you want to cut corners.

The charger that is designed for your Surface is what you should use. Using a third-party charger could cause the Surface itself to overheat or, at the very least, the charger will overheat again and you will be back to square one.

If your Microsoft Surface charger is buzzing, unplug the charger and inspect it for any visible signs of damage. Use the original charger that came with the Surface. Do not keep the charger plugged in for extended periods of time. Make sure the outlet is receiving enough electricity.
