What this means is setting the meter to show the maximum charge as 100% and the minimum as 0%. When the battery meter in the taskbar becomes this bad, you need to calibrate the battery. When I thought I had an hour or more left, it would shut down. The hours and minutes left was also way out.
I just couldn’t tell when the laptop would shut down on battery power and it could happen at anything below 50%. After a while it became 25%, then 30%, 40% – it was getting worse! At first the laptop would shut down when the battery indicator dropped to 20%. I was experiencing this problem first hand, so I know what a pain it can be.
This can result in the laptop shutting down unexpectedly. Sometimes the battery meter at the right side of the taskbar on Windows laptops becomes wildly inaccurate.
