It's so strange. Today when I turned on my laptop, suddenly, there was a message that my battery has problems so the computer might shut down suddenly. I tried different strategies, like uninstalling the battery driver, or letting the computer completely die. When it turned off itself at 6%, I turned it back on, and it was at 2 minutes battery life. Then in a few minutes, it said 4 minutes battery life for 6%. Now, it's passed an hour, and it says 3 minutes, but changes sometimes to 1-4 minutes. The battery meter is completely wrong, and I don't know what to do since it is closing the computer way too early. I'm still not sure what the problem is. Please help me.

How long have you been using the laptop with battery? Is it still under warranty?

Your battery may need to be recalibrated. To do that, charge your computer all the way.
Then turn off power saving features,such as hibernate at 10% or turn off monitor.

Then unplug the charger and brighten the screen and run several programs to drain the battery to zero.
Restart computer and charge all the way to 100%, make sure to not put it to sleep or turn off computer while doing this.

It should be calibrated after the performed procedures. If it dies too soon, it may be due to your battery charging capacity decreasing.
