Bug ID: 220142
Summary: HP Victus 15-fa0xxx – Deep Sleep (S3) Missing, Only
s2idle Available – Linux Suspend Broken
Product: ACPI
Version: 2.5
Hardware: Intel
OS: Linux
Status: NEW
Severity: high
Priority: P3
Component: Power-Sleep-Wake
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Description / Body:
Laptop Model:
Victus by HP Gaming Laptop 15-fa0xxx
OS & Kernel:
Debian 12 KDE
Kernel: 6.1.0-34-amd64
Issue Summary:
My laptop does not support deep sleep (S3) in Linux. The only suspend method
available is s2idle, which does not properly suspend my system. Instead, it
causes sleep to appear broken.
When I try to suspend:
The screen turns black,
Fans keep running,
Battery continues to drain rapidly,
Upon waking, it shows only a frozen cursor or crashes,
Sometimes it fails to resume at all.
This defeats the purpose of suspend and makes Linux nearly unusable on this
laptop.
Details & Reproduction:
I added the kernel parameter:
sudo kernelstub -a "mem_sleep_default=deep"
and confirmed it:
sudo dmesg | grep mem_sleep
[ 0.000000] ... mem_sleep_default=deep
But /sys/power/mem_sleep still says:
s2idle
If I run:
echo deep | sudo tee /sys/power/mem_sleep
I get:
tee: /sys/power/mem_sleep: Invalid argument
The BIOS has no options to disable Modern Standby (S0ix) or enable
S3/Legacy Sleep, so I can’t change this from firmware either.
System Output:
$ cat /sys/power/mem_sleep
s2idle
$ sudo dmidecode -s system-product-name
Victus by HP Gaming Laptop 15-fa0xxx
Why This Matters:
On Windows, this laptop uses Modern Standby, but on Linux this results in
s2idle, which keeps many system components (like CPU, RAM, fans) partially
active during sleep.
This leads to:
Very high power drain while sleeping (battery drops rapidly)
Incomplete suspension (components don’t power off)
Resume issues, like:
Blank screen with cursor only
System freezes or becomes unresponsive after wake
Linux currently depends on either BIOS support for S3 sleep or firmware that
allows ACPI control. Without this, Linux users can’t use suspend reliably on
affected HP laptops.
Request:
Please advise:
Can this laptop be made to support S3 via ACPI or kernel options?
Can OEMs like HP provide BIOS settings to enable S3 for Linux
compatibility?
This is a major issue affecting Linux users on modern HP laptops like the
Victus 15-fa0xxx.
