21 Aug Laptop keeps charging on and off? Find out the causes and fix it

I purchased a laptop and it was working fine. Suddenly, the next day, I noticed that my laptop would start charging and then stop. It continued to do this until I shut down the computer. I could not access Windows at all because the battery was too low. The weird thing is that when I turn on the laptop again, it’s charged 100%. Does anyone know why the laptop keeps charging on and off?

Why is my laptop charging on and off?

Your laptop battery could be dying or damaged if your charger isn’t able to charge fully the first time you plug your laptop in after shutting down. This can fix itself as long as you don’t leave your computer plugged in for more than 12 hours without using it (as doing so will damage the battery) but, in order to avoid this problem from happening again, you should try removing the battery and charging your computer with only the AC adaptor.

If your laptop is working ok after a full charge, you definitely need a new laptop. It sounds like there’s a lot of background processes going on in the operating (especially if it does so while shutting down). You shouldn’t have too many programs running while not using your laptop or they could cause damage to your computer and ruin its performance. Make sure that when you’re not using Photoshop, Word, etc., that you close them properly. On Windows 7 or Vista, click File > Exit while on XP or Mac OS X click the red button at the top left corner of the screen with an “X” on it.

Steps to fix laptop keeps charging on and off

First, you have to turn off your computer.

Secondly, press the power button for 15 seconds and then release it; this is just a safety precaution in case the laptop starts automatically while we work on it.

Thirdly, remove all cables from your notebook PC.

Fourthly, press down on the power button until you hear a long beep (about 5-7 seconds). This will drain out any excess electricity stored in your computer’s capacitors so that they don’t explode when installing new hardware or reinstalling Windows XP. You can also try removing them without pressing down on the power button because there are some laptops which have built-in protection against capacitor explosion by themselves(as long as their AC adaptor is constantly plugged in).

Fifth, remove the AC adaptor from your laptop and then install or reinstall the battery. Leave your computer for about 15 minutes. If you don’t use the original AC adaptor that came with your laptop, make sure you get a high-quality one that can output at least 5V / 4A of electricity; otherwise just wait patiently as it takes time for your notebook to charge up from 0%.

Sixth, plug in the AC adapter and boot up your computer.

Seventh, when Windows XP/Vista starts running, go to Control Panel > Power Options and click on “Never”. Don’t do this if you’re using Mac OS X because this will cause damage to your system files. Instead, go to Apple menu > System Preferences > Energy Saver. Then disable “Put hard disks to sleep when possible” and lower down the “Display sleep”, turning it off for short periods of time if required.

Final words,

If your laptop keeps charging on and off after following the steps above, it may be best just to get a new power adaptor and battery. Remember to take good care of your laptop’s battery as if you’re using a damaged or dying one then there’s no telling what damage that can do to your computer in the long run.
