How do computers keep time?
Yes computer keep their time appropriate even you power off, that is due to a small battery which is installed in every computer which keeps the time.
So the time which is running on the computer doesn’t depend on the power you supply it is depend upon a small battery which will work continuously. This is for laptops too, the time on the laptop computers won’t be depend upon the battery of laptop but there will be a small battery which is only specified for time.
Best laptops for programming under 50000.
