Over time, your ASUS laptop battery can lose efficiency. Poor battery life, failure to charge or overheating are all symptoms that it is time to act. Here is how to diagnose the problem and replace your battery properly.
Battery life and signs of wear
The typical lifespan of a laptop battery is between one and a half and two years. However, external factors or incorrect use can shorten this period.
Common symptoms of a worn-out battery
- Abnormal battery overheating
- Battery not detected by the system
- Need to stay plugged in to the mains to work
- Battery life dropping quickly despite a full charge
- Charge stuck below 100%
- Laptop refusing to power on
One or more of these signs should prompt you to check the condition of the battery.
How to diagnose a battery fault
Before replacing anything, here are two simple checks:
- Remove the battery and plug the laptop into the mains. If the laptop starts up normally, the battery is probably at fault.
- Use a hardware monitoring tool to compare the current capacity with the original one. A significant loss confirms wear.
Replacing the battery on an ASUS laptop: step-by-step
Even though some recent models require the chassis to be removed, the replacement process is still manageable for anyone who takes a bit of care.
1 – Fully power down
Start by shutting the laptop down and unplugging it from any power source.
2 – Access the battery
- If it is removable, turn the laptop over, release the latches and remove it.
- If it is built in, unscrew the underside of the case and carefully remove the bottom cover. The battery is generally located under the keyboard, near the screen.
Gently disconnect it.
3 – Identify the specifications
Note down the following information shown on the battery:
- Model number
- Voltage (V)
- Capacity (mAh)
- Energy (Wh)
This information ensures you make the right choice when buying a replacement battery. Choosing a higher capacity is possible, but be careful not to exceed a power rating that is too high.
4 – Fit the new battery
Connect the new battery, put the bottom cover of the laptop back, screw it down and check that everything is securely in place.
Best practices to protect your new battery
Here are a few habits to adopt to extend the lifespan of your new battery:
- Turn down the screen brightness
- Do not expose the laptop to heat
- Avoid leaving it plugged into the mains all the time
Recycling: an essential step
Used batteries contain polluting materials. Make sure you return them to a shop or drop them off at a dedicated recycling point.
In summary
Replacing a battery on an ASUS laptop is something most people can do with the right tools. By following this guide, you restore battery life to your laptop and avoid unnecessary expenses.
