41 ``temp[X]_label``       RO      Temperature sensor label.
42 ``temp[X]_fault``       RO      Temperature sensor fault indicator.

53 ``alarm`` attributes
54   Reading ``1`` instead of ``0`` as the ``alarm`` attribute for a sensor
57   - ``fan``: The fan has stalled or has been disconnected while running.
58   - ``temp``: The sensor reading has reached a critical threshold.
59     The exact threshold is system-dependent.
60   - ``intrusion``: The system's chassis has been opened.
62   After ``1`` is read from an ``alarm`` attribute, the attribute resets itself
76 system-dependent "platform events objects" used for ``alarm`` attributes may
77 be present. A debugfs interface is therefore provided for read-only access to
80 ``/sys/kernel/debug/hp-wmi-sensors-[X]/sensor``
100 ``/sys/kernel/debug/hp-wmi-sensors-[X]/platform_events``
122 - If the existing hp-wmi driver for non-business-class HP systems is already
123   loaded, ``alarm`` attributes will be unavailable even on systems that
125   for ``alarm`` attributes is used on those systems for e.g. laptop hotkeys.
126 - Dubious sensor hardware and inconsistent BIOS WMI implementations have been
129 - Only temperature, fan speed, and intrusion sensor types have been seen in
132 - Although HP WMI sensors may claim to be of any type, any oddball sensor
