High power draw from hid devices
Hello, My laptop (asus rog scar g15) (model G533zw 2022), has a strange problem, whenever I interact with touchpada or keyboard, power draw really goes very high relative to idle, idling at 4~ 5 watts "best so far", it can go up to 10 watts just because I *touched* the touchpad or pressed a button on the keyboard, to be specific for each device :
after freshly install and tweaking my arch installation it idles at 7 watts
keyboard is causing power draw of 3 watts all the time (or the usb controller is really what is causing this?),confirmed by setting the option for autosuspend "/sys/bus/usb/devices/{keyboardDevice}/power/control = auto" , power meter lowers to 4~5 watts and returns to around 7 ~ 8 whenever I press any button on the keyboard, I am writing this post and the power meter never got lower than 9 watts just because I a typing on the keyboard! (this allowed both the keyboard and the usb controller to suspend so I cannot tell which of them is causing the problem, I guess it is the controller itself, because external usb keyboard reprot same behavior)
for the touchpad , kinda similar, whenever I touch it even with one finger , not performing any multi-touch gestures, power draw also increases to around 8~9 watts, I also noticed that its driver is causing too much cpu interrupts, nearly half of the system's interrupts are from the touchpad, irqtop shows that core responsible for that driver has ~ 70% usage while all other cores never exceeded 10% each

I tried a solution regarding touchpad from similar issue in a framework laptop that suggested binding the gpio and the designware driver interrupts to same cpu core, but no luck
I am using sway and waybar
my power meter is literally /sys/class/power_supply/BAT0/power_now file
the laptop has D-gpu RTX-3070 Ti, but its is turned off all the time by supergfxctl utiltity from rog-linux community and appending kernel parameter supergfxd.mode=Integrated
I tried using vanilla, zen, lts, and G14 kernels all of them acted the same way as decribed above
anyone see where the problem is?

Re: High power draw from hid devices
I am writing this post and the power meter never got lower than 9 watts just because I a typing on the keyboard!
I suspect it has much more to do w/
I am using sway and waybar
Try to cause this while typing while logged into the console from the multi-user.target (2nd link below)

Re: High power draw from hid devices
I have set default target to multi-user and booted, logged in in tty and SSHed into it using my phone to record the power_now file and it is doing the same behaviour 7~8 watts idling before enabling autosuspend for the keyboard, after enabling it, it idled at around 4.8~5 watts and typing anything causes power to jump again to around 8 watts, I forgot to mention that I already using the laptop like login in at tty and then type sway to start it, not using display manager nor bash_profile to start sway automatically

Re: High power draw from hid devices
Please don't DM me for attention.
Sometimes things drop down in the stack of open tabs, if you want to push things, ideally do so by sharing what you've done in the meantime.
So
7~8 watts idling before enabling autosuspend for the keyboard, after enabling it, it idled at around 4.8~5 watts and typing anything causes power to jump again to around 8 watts
sound rather consistent (the load w/ the keyboard enables is 8W, idling it allows to go down to 5W but of course using it returns to the unidled draw)
I'd first and foremost check where the power is actually going (using powertop) - the keyboard itself (wired through i2c or i8042?) will hardly consume 3W by its sheer existence (does it have backlight?)?

Re: High power draw from hid devices
Ok sorry about that, so,
for powertop stats, when autosuspend is on, It can go down to 0 mw so I had to test that with autosuspend off,
if no button is pressed in a while it shows constant reading 1.78 watts and never got lower than this,but when I start typing ,it jumps to 2.08 watts,never got more than this even if continuously typing/pressing buttons
9.93 W 100.0% Device USB device: 2.4G Mouse
3.27 W 5.0% Device Display backlight
2.06 W 100.0% Device USB device: N-KEY Device (ASUSTek Computer Inc.) [b]This is the internal KB[/b]
777 mW 3.6 pkts/s Device Network interface: wlo1 (iwlwifi)notice also strangely my usb mouse/Kb combo is reporting this 9 watts
for its bus , I cannot fully confirm if it is i8024 or not, the keyboard itself is listed as usb device and /proc/bus/input/devices has these 2 sections :
I: Bus=0011 Vendor=0001 Product=0001 Version=ab83
N: Name="AT Translated Set 2 keyboard"
P: Phys=isa0060/serio0/input0
S: Sysfs=/devices/platform/i8042/serio0/input/input3
U: Uniq=
H: Handlers=sysrq kbd leds event3
B: PROP=0
B: EV=120013
B: KEY=402000000 3803078f800d001 feffffdfffefffff fffffffffffffffe
B: MSC=10
B: LED=7
I: Bus=0003 Vendor=0b05 Product=19b6 Version=0110
N: Name="Asus Keyboard"

U: Uniq=

B: PROP=0
B: EV=12001f
B: KEY=33eff 0 0 483ffff17aff32d bfd4444600000000 1f0001 1b30c730b17cc07 ffbf7bfad971dfff febeffdfffefffff fffffffffffffffe
B: REL=1943
B: ABS=10100000000
B: MSC=10
B: LED=1fso I am not really sure,i8024 is mentioned once and i2c none so I guess it is using i8024? (note that no external KBs were attached when I checked that to avoid confusion)
And regarding backlight, yes , it is an RGB keyboard(even has per key lights)but I don't use any rgb software, and its sysfs brightness file is 0 all the time, its lights glow only after waking from suspend or hibernate and turned off after few seconds
