  1. Max battery capacity dropped sharply in just 3 days


    Hi!I am really puzzled because in a matter of 3 days my battery max capacity has dropped really sharply and I do not understand why. It is a Lenovo Thinkpad P51. I had the maximum battery charge capped at 80% to have a better battery life and I kept it at 90% percent but it dropped to just 20%.Please help

    :)

  2. Battery capacity rapid drop

    I have a 4-month-old MSI Modern laptop with core i3 10110u 128Gb storage 8Gb ram. Very much base model type business laptop. I noticed recently my battery life was significantly less than it was the first month or so.

    Doing a battery report I noticed full capacity was now 31Wh vs new was 39Wh. MSI support suggested doing a battery calibration which I did, but another report after that showed the same loss of capacity. Now I am starting to think maybe the battery is defective, or is not charging discharging correctly? What are the criteria for the PC maker to determine the battery needs to be replaced under warranty.

  3. Full charge capacity of battery decreased

    Repeat the steps Dave suggest you other three times.

    Also you can uninstall and reinstall battery from device manager before each charge. You can do that:

    1. Press WINDOWS + X

    2. Click on "Device Manager"

    3. Click on "Battery"

    4. Right click on your battery

    5. Click on "Uninstall device"

    6. Repeat steps 4 and 5 for each element on battery list

    7. Click on "Detects Hardware change" (monitor icon)
