100S-11IBY : high battery draining in sleep mode (not hibernation)

Hello Lenovo users,

 

The sleep mode seems draining a lot a battery. According to my tests, only the screen is turned off.

 

The steps to reproduce the issue

0 - start a youtube video 

1 - close the lid -> the video is paused(no more sound)

2 - open the lid -> the video is resumed

3 - close the lid again -> the video is suspended for about 5 seconds before being resumed....

 

The computer drains about 2 watts in sleep mode : it seems close to the idle battery draining.

I really suspect that the computer does only turn the screen off.

A T420 laptop drains about 1 watts in sleep mode.

 

In hibernation, the battery draining is about 1 watt.

 

Is there any known bios issue ?
