When you plug in your laptop, you will be greeted with a joyful pleasure from your computer, a new glowing LED indicator light and a screen that perks up and radiates a little brighter.
At least that's what it should do Sometimes, however, you connect the AC adapter, usually because the battery is almost drained, and you get nothing. No light bulbs, no light screen and no "battery charging" icon in the corner. What can be wrong?
There are many ways to take care of your battery, but there are several steps and parts that can all fail between the wall outlet and the computer. Some are easy to fix yourself with a software adjustment or a new battery, but other problems may require a visit to a workshop store or even a fully exchanged system change.
Knowing which is which can save you hours of frustration and hundreds of dollars in repairs. By using an inside look you can quickly limit where the problem comes from and find the most economical solution.
Get ready, boys and girls, it's time to go troubleshooting.
Are you connected?
] It sounds silly, but you have to make sure the laptop is actually connected. No software tweak or hardware repair can make a connected laptop magical power on. So before doing anything else, make sure that the wall socket and the carrying plugs are properly seated.
Check the AC adapter and make sure that all detachable cables are fully inserted. Then check that the battery is firmly in its compartment and that there is no fault with the battery point or portable contact points.
Finally, find out if the problem does not even have to do with the laptop at all: Try connecting the power cord to another socket to see if you have a card or a blown fuse. (If it is connected to a surge protector or a power cable, remove it and connect it directly to the wall.)
At this point, we have determined that it is not only the user fault that causes the problem. There is a real issue with running the laptop; Now it's just about finding out where the problem can be. It starts with eliminating where it is. We start with the most common and easy-to-read problems.
Release the battery
First check the battery's integrity. If your notebook comes with a detachable battery, remove it and hold down the power switch for about 15 seconds to drain any remaining power from the unit. Then, with the battery still removed, plug in the power cord and turn on the laptop.
If the notebook is properly seated, it means the AC adapter is working properly and the problem is probably a bum battery. Even if you can always reinstall the battery and try again, the battery might only be worse.
If your laptop does not have a visible battery bay at the bottom, it can be built into the laptop (like most Mac computers), and you either have to open it yourself or take it to a repair specialist to test battery.
Make sure you are using the right USB C port
USB-C is a popular platform standard for connecting peripherals, data transfer and battery charging. The new standard enables thinner units, but can also cause some confusion. Some manufacturers have chosen to make some USB-C ports only data, so they do not charge your device.
For example, Huawei MateBook X has two USB-C ports: one that can be used for charging or data transfer and one for data transmission only. If you encounter a problem that is not charged, make sure you are connected to the correct USB-C port – you can even see a small icon on the page indicating which port to load.
Burnout and Shorts
Feel along the length of the power cord, bend and bend as you go, to check for any kinks or breaks. Check the ends for any broken connections, eg. plugs that release or stains that may have been chewed by a pet or trapped in a vacuum cleaner.
Check the AC brick. Is it discolored? Are some parts curved or expanded? Give it a sniff-if it smells like burnt plastic, it's likely where the problem lies. You may need to replace the power plug – contact the manufacturer and see if they are sending you a new one under the warranty. (Or exclude it if they sell you directly.)
Check the connector
When connecting the computer's power connector, the connection should be quite solid. If there is dust or other build-up inside the connector, a clean connection may not be possible. Try cleaning out the plug with a toothpick and reconnecting.
In more extreme cases, you can find that the jackets are wobbly or loose or give when it is to stay stuck. It may mean that the power plug has broken inside the chassis, and you have to take your computer to a workshop (or if you are comfortable opening it, do some repairs at home).
Turn on Heat
Batteries are susceptible to heat, so if your laptop overheats it can cause problems. When the temperature rises, the battery sensor may fail, which tells the system that the battery is either fully charged or completely missing, which causes charging problems. You can even discover that your system is turned off to prevent overheating of a battery and cause fire.
These problems become much more likely when you handle older laptops that have lower quality cooling than more modern devices – or if you usually use the laptop on the sofa or in bed , which can block the cooling valves . Turn off the system, give it some time to cool down and take time to make sure the air vents are free of dust and unlimited of blankets.
Check your settings
For Windows laptops
] In Windows 10, open the Start menu and search for "Power and sleep settings" and then click "Additional Power Settings". (On older versions of Windows, open the Control Panel and search for "Power Options.") Click "Change Plan Settings" and visually check that all are set correctly.
Look for incorrect settings for battery, display and sleeping options. For example, the battery settings can cause problems if you set the computer when it is lowered when the battery level drops or sets a low battery level too high.
You can also assign actions such as sleeping and turning off when the cover is closed or the power button is pressed. If these settings have changed, it is easy to suspect power outages even though there is no physical problem with the battery or charging cable. The easiest way to make sure your settings do not cause problems is to restore the power profile to the default settings.
For Mac laptops
In System Settings, select the energy saving window and review your settings. The Mac settings are adjusted with a slider and lets you choose how long the computer can idle until it goes to sleep. If the interval is too short, you can suspect the battery problem when the settings are the true culprit. And don't forget to check these settings for both battery power and wall outlet. You may want to return to the default settings to see if a change to the settings causes the problem.
Update your drivers
For Windows laptops
Open the Start menu and search for "Device Manager". Under "Batteries" you should see some things: usually one for the charger and one that is listed as "Microsoft ACPI Compliant Control Method Battery", although there may be others. Right-click each item and select "Update Driver".
When the drivers are up to date, restart the computer and reinsert it. If this does not solve the problem, you can download the latest drivers from the manufacturer's website . You can also try uninstalling the "Microsoft ACPI Compliant Control Method Battery" completely and restarting, which should cause Windows to reinstall the driver from the beginning.
