LEM HDD Power Saver how exactly does it work

Hi guys,


Lenovo Energy Management - Intelligent Power Saver - Hard Disk Drive Power Saver


Does anyone know how exactly does it work? What registry settings, power plan option setings and/or link power management settings are related to on/off settings of  HDD Power Saver?

Re: LEM HDD Power Saver how exactly does it work

hi bogdan_kr,


Welcome to Lenovo Community Forums!


   Lenovo Energy Management is known to take over the Miscrosoft Power Managment controllers.

Most of the settings inside can also be changed in th Built in Power options and some are Written by this software and cannot be found on the Built in Windows Power options and this feature is one.


The Hard Disk Drive Power Saver  puts the Harddisk on a much lower power state when the computer is on idle.


Hope this helps
