What does it mean if your Windows laptop shows “Consider Changing Your Battery”?

Posted on

QUESTION :

I am currently getting a a message saying “consider changing laptop battery” when my battery gets to 10%.

I also have a red X over the battery Icon all the time. I think my battery is ok though.

How can I check? Or how can I remove the error?

ANSWER :

This is how I check how well a battery is doing

  1. let it discharge completely.

  2. Time how long it takes to charge to
    100%.

  3. Remove AC adapter and time how long it takes to deplete if it’s dead in less than 35-45 mins. You probably need to replace it. How old is it?

Your laptop has software for monitoring the battery – showing the current charge, how much time it estimates you have before you need to recharge etc. This may also have access to historical data of charging times etc. or the expected charge times etc of your battery.

The software has detected that your battery is not holding it’s charge for as long as expected, or isn’t fully charging.

You should therefore consider changing the battery. You should be able to find one on-line. Either search for your laptop make and model plus the word “battery” or take out the battery and search for the make/model of the battery itself.

As long as you go for a reputable supplier (Amazon perhaps) then there is less likelihood of getting a counterfeit battery, or if there is a problem, more chance of getting a replacement or your money back.

I’m assuming this is an older system and the battery has gotten a considerable number of cycles, and a low capacity compared to the design capacity – MS has a writeup on this in their help site

If the battery actually works fine however, this may mean that something is off – some systems apparently misreport their battery capacity, and as such give the warning even when everything is working fine – a bios update may fix this.

There seems to be another fix for it here , tho this seems to be just settings tweaks

Whether you ultimately replace the battery or not, you should visit this website:
