The solution for battery failure usually will require BIOS update. This means you will need to download the flash update that should be available from your computer manufacturer's website. But there is a risk. You might end up with a defective motherboard. I suggest that you buy a new battery first. If the new battery works properly, then your old battery definitely needs replacement. If it doesn't, you definitely need to do an update. Just make sure that you have at least 10% battery charge and you keep the AC adapter connected. And nobody halt the update process.
