no sensor readings on HP Envy 15, firmware F.26

[Ákos Maróy]

after upgrading the BIOS to version F.26, no sensor readings are
available anymore. with the previous BIOS version, a CPU / motherboard
temperature sensor reading was available. the upgrade was necessary to
make poweroff and suspend work propely, see bug #557072

the output of sensors-detect after the BIOS upgrade:

# sensors-detect
# sensors-detect revision 5818 (2010-01-18 17:22:07 +0100)
# System: Hewlett-Packard HP ENVY 15 Notebook PC (laptop)
# Board: Hewlett-Packard 1522

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... No
Intel Atom thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Found unknown SMBus adapter 8086:3b30 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.
Module i2c-dev loaded successfully.

Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.

Hello
Is this problem present with the latest updates ?
Thanks
Fabio

[Ákos Maróy (akos-maroy)]

yes, it's still the same problem..

[Fabio Marconi (fabiomarconi)]

helloo
wich version of ubuntu are you using ?
