Query TUXEDO InfinityBook Pro 14 - Gen7

[Cpotts]

Yes, it is in assembly so I should have an answer in the next 2 weeks. I will be sure to post to this thread with results!

I can verify that the Infinitybook 14 pro gen 7 works wonderfully. I get the model without the 3050 and it runs my 5120 x 1440 monitor without a problem. Now if only the “suspend” issue could be resolved.

excellent! Thanks for your feedback

Hello Kate,

is it possible to deactivate the Intel Management Engine (ME) on the Tuxedo Infinitybook? I have read that this should be possible via the bios.

Thanks in advance!

Hi,

seems I’m in the same boat with a Tuxedo InfinityBook 16v7 (no nvidia, only intel graphics): Apart from sleep anything works great.

• Yes, you can disable Intel ME in the BIOS
• For thunderbolt 4 functionality you have to keep the NHI adapter in dom0 by adding rd.qubes.dom0_usb=00:0d.2 to your linux cmdline. This will enable DP over USB-C and provide you with the devices in /sys/bus/thunderbolt/devices, where you can choose to authorize them. If there’s somebody with a deep understanding of thunderbolt/usb4: Does this have any further security implications?

In regards to the sleep issue:

• The laptop announces both: s2idle and deep in /sys/power/mem_sleep
• I understand s2idle won’t work with Xen yet, see https://github.com/QubesOS/qubes-issues/issues/6411
• Same behaviour with stock TuxedoOS as in Qubes when trying deep sleep: Laptop won’t resume properly aka keyboard and fans will resume, but network, screen (and anything else?) will stay dead.
• Tuxedo support says they’re unwilling to fix deep sleep.

Since this isn’t satisfactory - any pointers to some documentation on how to debug deep sleep resume in linux would be great.

Thanks

Fwiw, I’ve managed to get my Tuxedo Infinity Book with linux powermanagement down to 6 Watt. It’ll get warm in the bagpack, but for me it’s enough to keep the engine running on a busy day.

NO warranties etc… This is NOT a fix. It’s just desperately trying to put this piece of hardware to work. There’s still the risk of overheating.

What I could not find out yet, is an equivalent for HW42s low power acpi profile for NVMEs. I run this script at lidswitch event via acpid. If someone has more ideas on how to improve power consumption, please let me know.

#!/bin/bash

if [ -z "$1" ]; then
	echo "  usage: $0 suspend|resume"
	echo "     This script initiates some pm measures on tuxedov7 to get power consumption down."
	exit 0
fi


if [ "$1" = "suspend" ]; then

        # disable tuxedo keyboard backlit ~2W
	sudo sh -c "echo 0 > /sys/class/leds/white\:kbd_backlight/brightness"

	# stop all VMs
	qvm-pause -q --all
	sleep 3
	
	# chill disk activities
	sudo sync
	sudo sh -c "echo 12000 > /proc/sys/vm/dirty_writeback_centisecs"

	# reduce cpu to one core with minimal frequency
	sudo xenpm disable-turbo-mode
	sudo xenpm set-scaling-governor powersave
	for i in $(seq 1 13); do sudo sh -c "echo 0 > /sys/devices/system/cpu/cpu$i/online" ; done
	sudo xenpm set-scaling-maxfreq 0 400000
	
	# activate pm for all pci devices
	for i in $(lspci | cut -d " " -f 1); do sudo sh -c "echo auto > '/sys/bus/pci/devices/0000:$i/power/control'"; done
	# disable touchpad
	sudo modprobe -r i2c_hid_acpi i2c_hid

	sudo sensors

elif [ "$1" = "resume" ]; then

	sudo sh -c "echo 500 > /proc/sys/vm/dirty_writeback_centisecs"

	for i in $(seq 1 13); do sudo sh -c "echo 1 > /sys/devices/system/cpu/cpu$i/online" ; done
	sudo xenpm enable-turbo-mode
	sudo xenpm set-scaling-maxfreq 0 2601000
	sudo xenpm set-scaling-governor ondemand

	sudo modprobe i2c_hid_acpi

	qvm-unpause -q --all

	sudo sh -c "echo 1 > /sys/class/leds/white\:kbd_backlight/brightness"

	sudo sensors
