Hi!
I have a ser7 7840hs.
But I don`t know how to get in s3-sleep mode in bios?

hello, it is already default to be S3, so you do not have to set it up, thanks

In s3-sleep mode, cpu is to be off,and cpufan is to be off,but cpu is on and
cpufan is on as usual.
How can I adjust this state?

hello, have checked that, sleep state has nothing to do with the fan rotates or not, if your machine gets hot, the fan will spin.

hi,
In sleep state,pc is not working, so there is no reason to be hot. And fan must be off.

PC power saving mode step-by-step description: Power saving mode is S1 to S4
means maximum power saving mode.

power saving mode S1,
the power of input/output devices such as disks (HDD, ODD) and
monitors is cut off with the PC on.
, the core parts of CPU, RAM, and VGA
operating normally, so the power saving effect is not significant.

, but when the movement of the keyboard or mouse is detected
the power saving mode is released.

power saving mode S2

mostly the same as S1, and the difference is that it does not release even with the movement of the keyboard or
mouse.

Power saving mode S3 preserves only RAM content and cuts off most
power of the rest of the devices. (Except for RAM update)

power saving effect is great, but errors occur if devices in the PC do
not support. The power saving state is released only by pressing the button of POWER
.

(when entering S3 power saving mode, CPU fan is turned off)

maximum power saving mode S4

RAM contents are stored on the hard disk
the power of the system is completely cut off.

When the system is turned on again,
data stored on the hard disk is restored to RAM again. Restore.
Because it completely cuts off power, the power saving effect is the
largest. When you press the POWER button, the power saving state is
released and detected and wakes up.

other power saving steps include

S0 step: Power on
S5 step: Power off

I guess you only have S0idle mode, like a cellphone, meaning the PC is always running. S3 does not exist anymore.

See for instance https://community.amd.com/t5/pro ... -laptops/m-p/616414

hello, for ser7840, it only has S4 and S5 option, how about you disable s4 and then see if that could work, thanks
