I've had my laptop for 8 months now, and just 20-30 minutes ago I've received this message: Consider replacing your batter, there is a problem with your battery, so your computer might shut down suddenly. I still have 3 year warranty, so I don't have a problem replacing the battery, but before I do so is there anything I can try?
I have an HP Pavillion if that helps.

I did the command prompt and it says: 6 errors, 21 warnings, 17 informational so I know that somethings wrong with it.
