SER9 sleep terminated by Lidstate open

Yamamotoy

Problem with SER9 sleep.

My SER9 only can be in sleep state for 3minutes. It wakes up without having any user input such as moving mouse nor wake on lan packet.
I use the following to see what made the SER9  wake up from sleep

powercfg /sleepstudy /duration 1

The log showed that wake up event was "LIDSTATE OPEN"
Please tell me how to prevent "LIDSTATE OPEN" happening.
