Guide to many friends have encountered such a problem-one day open the notebook, found that the electricity has been 100%, no matter how to use it will not lose power. However, the laptop cannot be a perpetual motion machine, and it will still run out when the power is used up. What users have observed is that when the battery still shows 100%, the computer will sleep or turn off.

The battery always shows 100%, and the remaining battery life is astonishingly long

Many people encounter this problem after upgrading Win10, and rebooting the computer can't solve it. But is this Win10's pot? Let's talk about how to solve it today.

First, let's talk about some of the performances of this Bug. First of all, the battery of the notebook has been shown to be 100%, regardless of charge and discharge, there will be no change.

Second, if you use software (such as AIDA64) to look at the current battery charge, you can find that the data is much higher than the maximum capacity, which is obviously wrong.

Wrong current battery capacity

Then, use Win10 search, find "Power Shell", use administrator privileges to run and enter the following command, you can directly copy and paste.

Powercfg / batteryreport

Press enter, and the system will generate a "battery-report.html" file in the C:\ Windows\ System32 directory, which is a detailed report on battery power. When it is turned on, you can see that at some moment, the battery suddenly explodes to an abnormal value.

A sudden surge in battery capacity in the system's power record

It can be seen that this Bug phenomenon is caused by the abnormal power data reported by the battery to the system. In fact, this is really not the problem of Win10, but the battery-powered Bug. Battery drivers are provided by device manufacturers, which has little to do with Microsoft.

How do I fix this Bug? In Win10, it may not work to restart the computer directly. Win10 introduces the feature of fast start, when shutting down, a part of the data of the current system will be written from memory to the hard disk so that it can start quickly next time, but this will cause some data, such as the drive status, can not be reset, such as abnormal battery power data will still exist.

What are we going to do? Forced shutdown is an effective solution. Press the laptop power button for a long time until the computer is forcibly shut down. Then reboot, at which point the battery drive will return to normal and the battery will return to normal display.

In short, this is a problem caused by battery drive, not Win10 itself. For many software problems, shutdown and restart is always an effective method. However, Win10 introduces a quick start, which makes a complete shutdown and restart difficult to achieve. Of course, the quick startup makes it impossible to shut down completely, not a Bug, but a Feature. If you also encounter incorrect battery display or other software-related problems, you might as well try this method.
