# Sleep
|

|

#
|
||||
# The system will not resume from sleep properly while on battery power in
|
||||
# either offload mode or sync mode. When it tries to resume, it gets to a
|
||||
# state with a cursor in the top left hand side of the panel, the power LED
|
||||
# goes from flashing to solid, and thereafter cannot be interacted with (even
|
||||
# over SSH) and must be power cycled forcefully. Sometimes it doesn't even
|
||||
# finish going to sleep before this behavior kicks in.
|
||||
#
|
||||
# When on AC, the machine either wakes up from sleep before being asked to
|
||||
# (or maybe never gets to sleep state), or it goes into a sleep state and it
|
||||
# appears consistently resume properly when it does.
|
||||
#
|
||||
# But the machine actually sleeps and resumes reliably when tlp is disabled
|
||||
# fully or partially. Disabling RUNTIME_PM and AHCI_RUNTIME_PM appears to be
|
||||
# enough to allow it to work when tlp is active. I couldn't figure out a
|
||||
# more granular way to get it working, despite trying to do a per-device

# the time the p53 profile was created (throttled's original name was
|
||||
# "lenovo_fix"). thermald would have been preferred if it worked at the
|

# time.
|

# I read

# https://wiki.archlinux.org/title/Lenovo_ThinkPad_X1_Carbon_(Gen_6)#Power_management.2FThrottling_issues
|
||||
# as saying that thermald is fixed under the circumstance that led to the
|
||||
# development of throttled given version 5.12+ of the kernel combined
|
||||
# with version 2.4.3+ of thermald. At the time of this writing, the
|
||||
# stable NixOS kernel is 5.15 and 2.4.9 of thermald.
|
||||
#
|
||||
# In the meantime, I also ran the "s-tui" program which can stress test the
|

# system, while eyeing up the core temps and CPU frequency under three
|
||||
# scenarios: under thermald, under throttled, and with neither. None of the
|

# scenarios seem to have massively improved fan behavior, core temps, or
|
||||
# average CPU frequency than another. The highest core temp always seems to
|

# hover around 90 degrees C, the lowest CPU Ghz around 3.4 on a 3.8Ghz machine.
