Solve the problem that the laptop prompts "please consider changing the battery" in Windows 7.

 

Windows 7 has been installed for more than half a year, but the day before yesterday morning boot, suddenly found in the lower right corner of the computer battery Red Cross, prompt "please consider changing the battery" and "your battery problems, this may cause your computer to suddenly shut down ".

After searching on the Internet for a long time, I finally found a solution and the experiment was feasible.
