When you connect your laptop charger, you usually see an LED that indicates that the battery charging process has started normally. However, sometimes you plug in the charger and get no response. No indicator lights come on or battery is charging What could be happening? We explain what to do if your laptop battery does not charge .
Check that everything is well connected
It sounds silly, but you have to make sure that the laptop is actually connected . Therefore, before doing anything else, make sure the charger's AC outlet and the laptop's connector are properly seated.
Check the charger's AC adapter and verify that the detachable cables are fully inserted . Next, make sure that the battery is seated properly in its compartment, and that there is nothing strange about the contact points of the battery and the laptop.
Finally, find out if the problem has something to do with the laptop. Try plugging the power cord into another outlet to see if you have a short circuit or a blown fuse.
After that we will have determined that it is not a user error that causes the problem, but that there is a real problem with the laptop's power supply.
Check the battery
First, check the integrity of your laptop battery. If your computer comes with a removable battery, remove it from the computer and press and hold the power button for about 15 seconds to use up residual power. Then, with the battery still removed, connect the power cord and turn on the laptop.
If the laptop turns on correctly, it means that the power adapter is working properly and the problem is probably due to the battery. You can always reinstall the battery and try again, the battery might not be seated properly after all.
Make sure you are using the correct USB-C port
USB-C is a very popular cross-platform standard for connecting peripherals, transferring data, and charging the battery. The new standard allows for slimmer devices, but it can also cause some confusion. Some manufacturers have chosen to make certain USB-C ports data-only , so they are not suitable for charging the device.
If you run into a no-charge problem, make sure you are using the correct USB-C port. You can see a small icon that indicates which port is enabled for battery charging.
Check if the charger is damaged
Examine the power cord, bending and flexing it as you go, to see if there are any kinks or breaks. Check the ends to see if there are any broken connections or spots that may have been chewed on by a pet or caught in a vacuum cleaner. Also inspect the body of the charger and sniff, if you smell burned plastic , this is probably the problem.
Check if the connector is dirty
If there is dust or other build-up inside the charger's power connector, it may not be able to make good contact with the notebook's circuits. Try cleaning the connector with a toothpick and some rubbing alcohol before reconnecting it again. You can also use an ear pick to clean the outside of the connector.
Beware of the heat
Batteries are susceptible to heat, so if your laptop overheats it could be the cause of the problem. As the temperature of the battery rises, the sensor may fail indicating to the system that the battery is fully charged or that it is not mounted. The system may shut down to prevent the battery from overheating and starting a fire.
You can use a cooling base to avoid overheating your laptop in the hottest times.
Check your battery settings
In Windows 10, open the Start menu and search for " Power and Sleep Settings, " then click "Additional Power Settings." After that, click on " Change plan settings " and visually check that everything is properly configured. For example, the battery settings can cause problems if you set the computer to turn off when the battery level gets too low, or if you set the low battery level too high.
Update battery drivers
Open the Windows 10 start menu and search for " Device Manager ". Under "Batteries" you should see a few items, usually one for the charger and another listed as "Microsoft ACPI Compliance Control Method Battery," although there may be others. Right click on each item and choose " Update Driver ".
After that, restart the laptop and reconnect the battery. If this doesn't solve the problem, you may need to download the latest drivers from the manufacturer's website.
Change the cable and battery
If the above tricks don't work and you haven't been able to fix your low battery power issue, you may need to buy a new battery or a new power adapter. The decision will depend on what you have been able to reduce with the previous steps.
You can find a replacement power cord or battery on Amazon, but make sure it's a legitimate part from the original manufacturer . Replacement parts from other manufacturers can be of poor quality and even dangerous.
It is best to contact the manufacturer directly and request a replacement part. It will be a little more expensive, but you will be sure that you are receiving a quality component.
Possible problems inside the laptop
If you have exhausted all the options, have tried other power cables and batteries and have been able to solve the problem, it is possible that the source of the problem is inside the laptop. There are several internal parts that can cause problems with battery charging when they malfunction.
