Do you have doubts about your computer battery, or simply want to prevent battery replacement? In this article, I explain how to recognize if your laptop battery is worn out.

5 symptoms of a worn-out laptop battery

There are several signs that your laptop battery is worn out and needs replacing. The most common symptoms are :

  • Reduced battery life
  • Loss of fast-charge capacity
  • Charging problems
  • Battery errors in the device manager
  • Computer only works when plugged in

Battery discharges faster

Over time, batteries lose their ability to store energy, resulting in a shorter service life. This is a normal phenomenon affecting all rechargeable batteries. So when your laptop battery shows signs of discharging faster than expected, it could well be the result of this gradual degradation of its energy storage capacity.

Loss of fast-charge capacity

The battery takes much longer to fully recharge. Sometimes it seems to stagnate at a certain percentage, without ever reaching 100%. What’s more, you notice that you need to recharge your laptop much more often, even for moderate use. These are clear signs of battery deterioration, and suggest that it may be time to think about replacement.

Computer no longer loads

Charging problems may also indicate that your battery is worn out. If you have difficulty charging the battery, or if it doesn’t charge properly, this could be a sign that the battery is at the end of its life. Here are some symptoms associated with a worn-out battery:

  • The laptop does not switch on at all, even when plugged into the mains.
  • The notebook suddenly shuts down, even though the battery is supposed to be full.
  • The battery charge indicator does not light up or flashes when the notebook is plugged in.
  • The battery charges very slowly or not at all.

Battery errors in the device manager

Finally, if you receive battery errors in the Device Manager, it’s possible that your Medion battery is worn out. These errors may include warning messages indicating that the battery is faulty or needs replacing.

Computer only works when plugged in

The computer works only when connected to an external power source. As soon as you disconnect the charger, the computer shuts down instantly and cannot be restarted without reconnecting to the mains. Once restarted, the battery gauge remains frozen at 0%. In this scenario, the battery is clearly at fault.

You’re faced with two options: either continue to use your device by leaving it constantly plugged in, which can be impractical for a laptop intended to be moved around a lot, or consider having it repaired.

How to replace your worn-out laptop battery?

If you’ve identified one or more of these symptoms and suspect that your battery is worn out, it’s time to move on to battery replacement. Here are some of the options available:

  1. Contact the manufacturer: You can contact your laptop manufacturer directly to obtain a genuine replacement battery compatible with your specific model.
  2. Buy online: Browse reputable online retailers to find a battery compatible with your laptop model. Make sure you choose a quality battery and check user reviews to ensure product reliability.
  3. Call in a repairman: If you’re not comfortable doing the replacement yourself, you can call in a computer repairman. Make sure you choose an experienced and competent professional to guarantee a safe and efficient battery replacement.

Whichever option you choose, be sure to follow the instructions supplied with the new battery, or call in a computer repairman to carry out the battery replacement and ensure correct and safe installation.
