Windows 10: Windows 10-64 version 1903, HP Envy 13-aq0045cl Power Throttling under CPU Load

I would like to know how to disable "battery saving" CPU downclocking on my HP Envy 13-aq0045cl serial number 8CG9177Z3X with Win10 Home. Upon a fresh boot, this computer increases CPU clock speed when under load as is advertised by HP (my desired mode of operation), but after a short while (10 to 30 minutes), it INSTANTLY (like a switch flip) reverses its throttling scheme such that the CPU clock is significantly reduced when under load (performance behavior never mentioned in HP's advertisement glossy for this computer and definitely NOT my desired behavior). I've seen the clock drop lower than 300MHz when applications (Chrome or Firefox) are started which causes serious interruptions in audio playing in the background. This performance is unacceptable. Each time this happens, I can only restore proper performance by rebooting the computer, but after another 10 to 30 minutes, it flips its throttling scheme again and performance becomes unacceptable. The CPU downclocking mode NEVER reverses itself; once the downclocking mode starts, it's as if Windows gets stuck in this mode and only a reboot will fix it (and only temporarily at that).



I am not running any computationally intense applications on this computer (e.g. no video games or other real-time rendering applications). I am mostly running web browsers when the CPU throttling becomes problematic and almost always have a background audio stream running which gets totally destroyed when the CPU downclocks.



So far, I have done the following to try to fix this behavior:
(1) Within Windows "Power Settings", I have configured the plugged-in "minimum processor state" to 100% and "system cooling policy" to "Active".
(2) I've ensured the latest BIOS is installed (Insyde F.05-04/29/2019).
(3) I've ensured I've got all of the latest device drivers installed.
(4) I've performed diagnostics with "Core Temp" version 1.14 to confirm CPU downclocking is not due to high CPU core temperatures.
(5) I've tested the computer with higher wattage power supplies to ensure the computer itself isn't limited by power supply capacity.
(6) I have added a registry key "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerThrottling" with DWORD "PowerThrottlingOff" set to 1.
(7) Within the group policy editor (gpedit.msc), I have set "Local Computer Policy/Computer Configuration/Administrative Templates/System/Power Management/Power Throttling Settings/Turn Off Power Throttling" to "Enabled".



One thing I have been unable to do is confirm Power Throttling is disabled in the BIOS. Unfortunately, the BIOS settings don't include this option so I can't tell if Power Throttling is enabled or disabled in the BIOS and, if it is enabled, I can't turn it off.



I've chatted extensively with HP Support regarding this issue. Here's what I was told:

(1) While the BIOS presents no user-selectable option for "Power Throttling", the BIOS is enforcing "Auto" for this setting. Setting "Power Throttling" to "Auto" within the BIOS leaves total control of power throttling to the Operating System.

(2) HP can't be expected to make statements about computer performance when running "3rd party" (non HP) software like Firefox, Chrome, and Microsoft Office.

(3) To continue my pursuit for a solution through official HP channels, I must open an account with "Tier 2 Support" (something called "Smart Friend", a pay-for-service support option).



I really like this laptop and I'd like to keep it. I just need to know how to REALLY disable Power Throttling so that it will work properly for longer than 10 to 30 minutes following a reboot. Any advice would be GREATLY appreciated!

HP Envy Laptop 13-ad1xx Windows April 1803 Update

Hi,

I was just wondering if my HP Envy Laptop 13-ad1xx has made some sort of can't install update list at Microsoft? I have been getting:

Microsoft: Your PC hardware is not supported on this version of Windows 10. Contact your PC manufacturer for more information.

My laptop is listed as tested and compatible on HP's website. I am currently running Windows 10 Pro 1709 (16299.371).

I'll wait it out for a while and see if it ends up working but mostly just curious if anyone else is having this problem. I did upgrade from the stock Windows 10 Home to Windows 10 Pro via Microsoft Store if that makes any difference.

Thanks!
