My laptop started crashing out of nowhere recently. It looks like the battery has died, then I plug it in and restart it. When it turns on the battery is at 100% and i can unplug it again and continue working without being connected to power. No matter how long I work the battery doesn't budge from 100%, sometimes that's days of use and it's completly cut off power. I do have to add that I changed the battery a few years ago, also the laptop is 5-6 years old. Laptop model: Acer Aspire E15
Thank you to anyone that takes the time to read this and possibly help me with this problem. Have a nice day
