BIOS F.08 HP Pavilion Gaming Laptop 15-ec0xxx shutdown/hibernate

HP Recommended
HP Pavilion Gaming Laptop 15-ec0xxx
Microsoft Windows 10 (64-bit)

I have the same problems of all of you and my temporary workaround is Ryzen Controller with Temperature Limit capped at 75°C.


I can confirm what another user posted: if I manually set the fans to the maximum speed, the system immediately hibernate itself, even if the temperature was around 45°C.

Windows Event Logger says the temperature was 100°C (_HOT = 373K), but its clearly wrong.


My 2 cents: in the bugged BIOS, they swapped references to fan and temperature value, so the system believes the CPU temperature is 100°C and triggers the shutdown/hibernation, but it's not! The fan is the one at 100 (%, not °C of course), not the CPU.

I'm a software developer, so I know that wrong references could happen 😋


Maybe it's not a wrong reference, but it seems related to the maximum speed of the fan, rather than the real temperature (and it could explain why shutdowns happen at variable temperatures). Maybe fans at maximum speed are absorbing too much power and interferes with temperature values communication, I don't know.   


These are my steps:

  1. Downloaded and installed Notebook Fan Control [content removed]
  2. Selected config for HP Pavilion 17 (even if my PC is Pavilion Gaming 15).
  3. Set Enabled (not read-only) and moved the slider to 100%.
  4. Fans speed up, but no shutdown.
  5. Noted that fans are not as loud as they are when my pc usually shutdown
  6. Opened Notebook Fan Control Config Editor and edited the config to match my fans very 100% speed.
  7. Loaded HP Pavilion 17 preset. In Fan Configuration tab, raised up Max speed to 110. Saved this profile as HP Pavilion Gaming 15.
  8. Returned to the app, loaded my profile, set fan to maximum.
  9. The speed is read as "180%" (or something similar) and now it's very loud!
  10. BOOM! System shutdown, even if the temp was around 46°C.
  11. In Windows System Events, I can read (sorry, my OS is italian):
    Ibernazione del sistema a causa di un evento critico relativo alla temperatura.
    Ora ibernazione = ‎2020‎-‎08‎-‎27T14:13:05.801986200Z
    Zona termica ACPI = \_TZ.THRM
    _HOT = 373K


You can test other fan control software, this is the first I was able to get working.


Maybe we could test if setting the fan at fixed speed just below the maximum speed could avoid system reboots.


My PC complete specs:

HP Pavilion Gaming - 15-ec0024nl

Ryzen 5 3550H

GFX 1650 Max-Q

32GB RAM (updated aftermarket - 2x16GB Crucial 3200MHz)

Stock 512GB NVMe + 1TB SSD Sata (added aftermarket)

this is my finale (?) workaround:


Ryzen Controller 2.2.4

  • Temperature limit: 75°C
  • CPU TDP: 35W
  • Long Boost TDP: 25W
  • Short Boost TDP: 35W
  • Everything else unchecked

NoteBook FanControl

I created my imperfect profile based on HP Pavilion 17 (the easiest way I found), with this changes:

  • Basic configuration: critical temperature raised up to 85°C (to avoid automatic fan max speed).
  • Fan configuration: max speed raised up to 120.

Set the FanControl app to:

  • Fan control service status: Enabled
  • CPU Fan 48.8%. Weird value, but for me it's working nice.
  • Current fan speed will result 116.0% and you can hear it not as loud as maximum speed, sounds like the step just before.

With these settings (and a room temperature around 25°C), the CPU is really really cold (under 40°C) at idle, 45° during normal usage, 60-70 during games (with a max peak value of 80°C). Maximum CPU speed is around 3.0 - 3.2 GHz, which is fine for work and non-demanding games (I'm testing with XCom2). 


Everything is working fine for now.


I would like to change the thermal paste and try to undervolt the GPU, in order to get lower temperatures and better performance (due to faster boost frequencies).


But above all, I'm waiting for a new bios update!!!

Are there any leads on the BIOS update? All the HP customer support agents are basically stalling. I bought my laptop and it came with the BIOS version F.08. So, I can't even roll back to the previous stable version. Help!

F.10 version was released on August 27th and it's working fine:


You can also downgrade the bios to F.05 by following the procedure posted on this forum (search for it), but you better update the bios.
