How to Fix a Laptop That Is Not Charging

This How.com.vn teaches you how to figure out why your laptop isn't charging while plugged in. Charging issues are most often the result of faulty power adapters, non-working power outlets, or bad batteries. If everything checks out okay with the hardware, you can usually fix power issues by updating your laptop's power or battery management settings.

How to Fix Laptop If Charge Port Is Not Working

The first thing you should do is check if the charging port has a good connection with the adapter and charging brick. If the charging port and cable looks okay, then check the power jack on the laptop—a jack that jiggles may be faulty.

Plug the laptop into a different power outlet. Unplug the laptop, wait a few minutes, and then plug it into an outlet on a different wall or room. If the laptop charges when connected elsewhere, the problem is not your computer or charger.
- To confirm whether the laptop is charging, check for charging lights. Many laptops have a light somewhere on the machine that indicates whether it's receiving power. Sometimes it'll be above the keyboard, other times it'll be on the side or back of the unit. If you're using a Mac laptop with a magnetic charging cable, you'll see a light on the end of the cable where it connects to your computer (orange = charging, green = fully charged). Other times you'll find lights on the power cord, especially if there's a "brick" aspect of the cable.
- If the power adapter works for a little while but then turns off, there may be interference with the outlet. Unplug the power adapter for about 30 seconds and then try again.^{[1]XResearch source}
- If the adapter or the computer itself feels unusually warm, wait until the surface has cooled completely before plugging it into a power source.
2
Inspect the power adapter. Examine the entire length of the power cord for tears, dents, and worn-down insulation. If you notice any flaws, or if the power brick is warped or smells like burnt plastic, the cord is probably faulty.^{[2]XResearch source} Try bringing the laptop to a local repair shop and ask to try one of their working power adapters. If a verified-to-be-working adapter charges your laptop, order a replacement adapter.^{[3]XResearch source}
- If you're using a newer PC model that supports USB-C charging (such as the Huawei MateBook X), make sure your power adapter is plugged into the correct port on the laptop.^{[4]XResearch source} Usually only one of the USB-C ports on such models support charging, while the other is used only for data transfer.
- Check your warranty before replacing any parts, as the cost of the adapter may be covered.

A dead adapter is one of the most common reasons your laptop isn't charging. Check whether the charging port is making a good connection with the adapter and charging brick. Also, the plug that goes into the laptop might be worn out from use.

Check the power jack on the laptop. When the adapter is connected to your laptop properly, it should not jiggle or fall out of the jack. If the connection feels loose, there could be a bent pin inside the power jack. It's also possible that the entire jack has loosened from the motherboard. Take the laptop to a repair shop for a proper diagnosis.
- Bent pins and other power jack issues are model-specific. You can look up your model online for repair instructions, but the repair usually requires purchasing a new power jack and soldering it onto the motherboard. This could void your warranty.
4
Start up your laptop without a battery. Shut down the computer, remove the battery, and plug the computer in. If the laptop wasn't powering on before but works without the battery, you may need a new battery. Another method may fix the problem, or your battery may be dead and require replacement.^{[5]XResearch source}
- If your laptop battery is not removable, skip this step and try the methods below before taking your laptop to a computer repair store.

Open your Windows Settings
. You can get there by right-clicking the Start menu and selecting Settings.^{[6]XTrustworthy SourceMicrosoft SupportTechnical support and product information from Microsoft.Go to source}
Windows allows you to customize certain power and battery settings on your laptop. There may be a low-battery level alert that's too sensitive causing your PC to shut down when the battery is low.
3
Check the values in the "Screen" and "Sleep" menus. In particular, make sure the values of both "When plugged in" menus aren't set too low.^{[7]XTrustworthy SourceMicrosoft SupportTechnical support and product information from Microsoft.Go to source}
- For example, under the Sleep header, if 10 minutes is selected from the "When plugged in" menu, the PC will turn off after 10 minutes of inactivity when plugged in. Raise that amount to prevent unexpected shutdowns.
A list of your power plans will appear.
Just as you did in the last area, make sure none of your settings are configured to shut down your PC unexpectedly.
6
Click Change advanced power settings. It's near the bottom of the power plan.^{[8]XResearch source}
- Once quick way to fix any missteps in this section is to click Restore plan defaults at the bottom-right corner of the dialog, but this will erase any power customizations you've added.
7
Check the values of the "Battery" section. If you clicked Restore plan defaults in the previous step, just skip to the next step. Otherwise, verify that the following settings are correct:
- Under "Critical Battery Action," make sure Do nothing is selected for "Plugged in." Otherwise, your computer will shut down at a certain battery level if it it's plugged into a power source.
- Under "Low battery action," also select Do nothing for "Plugged in."
Now that you've updated your power settings, reboot your PC to see if the issue is resolved. If you're still having trouble, move to the next step.
You can do this by right-clicking the Start button and selecting Device Manager from the menu.^{[9]XResearch source}
A list of all battery-related drivers will appear. You'll usually see one entry for your AC adapter and another for the battery itself.
If you see two different entries under Batteries, do one after the other. Follow any on-screen instructions that appear to update drivers if necessary.
Restart the computer. Shut down the computer and start it up again, so the driver will take effect.
13
Uninstall and reinstall the driver. If you still cannot charge your laptop, return to the Batteries section of Device Manager, right-click Microsoft ACPI-Compliant Control Method Battery, and then select Uninstall. When the process is finished, click the Action menu and select Scan for hardware changes. Restart your computer once the driver is reinstalled.^{[10]XResearch source}
- This step requires an internet connection on your laptop.

Checking Mac Power Settings

Sometimes Apple releases new updates that can help your computer work well with the power adapter.^{[11]XResearch source} To check for updates, click the Apple menu, select System Preferences, and then choose Update Now if an update is available.
2
View your battery health status. To find out the condition of your battery, hold the ⌥ Option key as you click the battery icon in the menu bar. This displays the Battery Status menu, which will display one of the following status indicators:^{[12]XResearch source}
- Normal: The battery is working properly.
- Replace soon: The battery is working normally, but is no longer at full capacity. This is not time to panic, but you should definitely check the status frequently to make sure it doesn't get worse.
- Replace now: The battery works normally but its capacity is significantly lower than it was when brand new. You can still use the laptop, just make sure you always have a power cable handy until you can replace the battery.
- Service Battery: The battery is not working properly. You should still be able to use the computer with a power cord connected, but the battery will likely not work on its own. Bring the computer to the Apple-authorized service provider as soon as possible.
If your computer is turning off unexpectedly, it may be related to incorrectly-set power settings.^{[13]XResearch source} In the Apple menu, click System Preferences, select Energy Saver, and then click Power Adapter to see check out what your computer's set to do when plugged in. Make sure the "Turn display off after" slider is not set to sleep after a brief period of inactive time.
If you're still having trouble, the remaining steps will help you reset the System Management Controller (SMC), which can help resolve power problems.^{[14]XResearch source} Begin by making sure the computer is turned off and not plugged into a power source.
Don't turn the computer on, just plug it in for now.
After holding the buttons down for about 4 seconds, lift your fingers from the keyboard.^{[15]XResearch source}
This will power your Mac back on. Once it comes back up, the SMC will be reset, hopefully clearing up any residual power issues.^{[16]XResearch source}

My charger is plugged in, the light is on and it says 0% available (plugged in, charging) but it's not charging. How can I fix it?

Some charger models are poorly built and may allow you to accidentally flip the electrical current. Just to make sure, try unplugging the adapter, rotating it 180 degrees, and putting it back in.
