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.
