Like all batteries, the one in your Acer Aspire One has a finite lifespan. If your battery isn’t charging, you may have to purchase a replacement, but there are several fixes you should try first. Many different problems can prevent the battery from charging, so the fact that it doesn’t appear to be working doesn’t necessarily mean you have to spend money on a replacement. There are two different solutions to the issue, which generally depends on whether or not the orange battery LED is constantly blinking.
Remove the battery from your Acer Aspire One. Slide the lock on the battery into the “Unlocked” position to remove it from the laptop. The electric connection runs through the contacts you’ll see on the edge of the battery which ordinarily points towards the inside of the laptop. Wipe these contacts with a lint-free cloth, because accumulated debris can prevent the connection from working properly.
Update your BIOS. Visit the “Drivers and Manuals” page of the Acer website (see Resources), and select “Netbook, Chromebook” and “Acer Aspire One” before choosing your specific model. Choose your operating system and select the “BIOS” tab. Choose the orange icon to download the updated version of BIOS and then save the ZIP folder to your desired location. Extract all files from the folder, and enter the subfolder with the same name as the main one. Right-click the “3310.fd” file and rename it “zg5ia32.fd” (without quotations).
Copy the “zg5ia32.fd” and “Flashit.exe” files to your removable USB drive. Switch off your laptop and keep the USB drive plugged in. Press and hold the function (“Fn”) and “Esc” keys and press the power button. When the power light comes on, release the “Fn” and “Esc” keys. The power light will start to blink. Allow the laptop to run, and it will restart within around seven minutes, with an updated version of BIOS.
Ensure other causes aren’t responsible. If cleaning the contacts and updating BIOS doesn’t work, there is a small chance that other issues are responsible. Check the power outlet that you’re using works (try another appliance in it) or just try a different one. If you have a spare power cable, see if your laptop charges when you use it. If it does, you just need another power supply.
Blinking orange battery light
Remove your AC power supply and take the battery out of your laptop. If the orange light is blinking but you can’t charge your laptop, you might need to perform a static discharge of the motherboard.
Press and hold the power button of the laptop for 10 seconds and then release it. Plug in the AC adapter again and wait a few seconds.
Insert the battery again, ensure it’s in the “locked” position, and turn the laptop back on. This should rectify the battery issue, but if it doesn’t consider purchasing a replacement.
