Battery drain in Hibernation after installing "Lenovo - System - 10.0.127.0" on Windows 10 2004

[havx]

My ThinkPad X1 Carbon Gen 7 (Model: 20R10015US) gots 0.7% battery drain per hour in average while in hibernation mode, after installing "Lenovo - System - 10.0.127.0" via Windows Update / Driver Update. Before this update, the battery drain in hibernation mode is near zero. The battery cycle count also increases quickly after hibernation: one cycle counted for 20-30% accumulative battery drop.





I did shut down the machine for 11 hours, no battery drain happens.



*** Please help me fix this issue.
