Changes

1. There are 4 version of X735: V1.0, V2.0, V2.1, V2.5 (final version):

<span style="color:red;">Version 2.5</span>(Updated on Mar. 15th, 2021): use the silent PWM cooling fan, support TRUE AUTO ON function (in the old version,the power management function is disabled if AUTO ON is enabled), and support fan speed is control by script, support read fan speed, and we provide sample ruby code.

<span style="color:red;">Version 2.1</span>(Updated on Oct. 30th, 2019): Only change jumper 'FAN_HS' to 'AUTO ON' function; because we found 'AUTO ON' function is more useful to user.
