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 ?
