HP Omen 17 GPU power capped.

[ASwaff]

For the past month, my laptop (HP Omen 17, Nvidia 2070)would occasionally slow down massively (140fps -> 18 fps) after being on for a while, which was solved by a reboot. As of three days ago, it now is almost always that slow, even from startup, which seems to be due to GPU power limiting. According to GPU-Z, whenever this is happening, the GPU clock on the 2070 is limited to 300Mhz, and I get a perfcap reasoning of "pwr" constantly, even when just sitting idly on chrome. Occasionally after a restart it works a little before this kicks in, so I know the GPU is still functional, but it's rare. Trying to diagnose the problem so I can fix it (or be certain it's unfixable).

Have tried:
Replacing the AC adapter

Reinstalling the Nvidia drivers (with and without using DDU to wipe them)

Removing geforce experience and altering Nvidia settings.

Fully updating windows, bios, etc.

Running all HP Component checks.

Disabling and re-enabling from device manager.

Physically disassembling and examining the motherboard for any obvious issues.

I did have to replace the power jack that the adapter plugs into at one point, and I did notice that when charging, I get "plugged in" instead of "plugged in, charging", even though it still charges. Likely unrelated but if there's any chance that could be the issue (though it's genuinely just wiring) I thought it would be worth mentioning. Completely lost and hoping I don't have to trash the whole thing.

Thanks

Hi @ASwaff,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you've already done extensive troubleshooting for your HP Omen 17 laptop. The issue you're experiencing with the GPU being power-capped is indeed frustrating. Given the symptoms and the steps you've already taken, here are a few more potential solutions to consider:

Check Power Settings and Plan:

• Make sure your power settings are set to "High Performance". Sometimes the "Balanced" or "Power Saver" plans can throttle GPU performance.
• Go to Control Panel > Power Options and select High Performance.

Check for Thermal Throttling:

• Use a program like HWMonitor or MSI Afterburner to check your GPU and CPU temperatures. High temperatures can cause throttling to protect the hardware.
• If temperatures are high, consider cleaning the cooling system, reapplying thermal paste, and ensuring the fans are working correctly.

Inspect Power Jack Replacement:

• Since you mentioned replacing the power jack, ensure the replacement is properly installed and making a good connection. A faulty power jack could potentially cause power delivery issues.

Check for Malware or Background Processes:

• Sometimes, malware or background processes can cause significant slowdowns. Run a thorough scan with a reputable antivirus program.
• Open Task Manager (Ctrl + Shift + Esc) and check for any unusual processes that might be consuming resources.

Nvidia Control Panel Settings:

• Open the Nvidia Control Panel, go to Manage 3D Settings, and ensure the Power management mode is set to Prefer maximum performance.

Check BIOS Settings:

• Enter the BIOS (usually by pressing F10 during startup) and ensure that any power-saving features are disabled.
• Look for options related to power and performance and make sure they are set to performance-oriented settings.

Test with an External Monitor:

• Sometimes, issues with the internal display or its connection can cause performance problems. Test your laptop with an external monitor to see if the problem persists.

Battery Health Check:

• Check the health of your battery. A failing battery might cause power issues. You can do this through the HP Support Assistant or by running a battery report (command prompt: powercfg /batteryreport).

Consider a Factory Reset:

• As a last resort, consider backing up your data and performing a factory reset to rule out any software-related issues.

Hello Gaya,

Have just gone through most of those:
External screen did nothing, had checked battery health through that method already.

Power jack remained concerning, but it had worked for a while, no way to check that besides getting a new one.

Nvidia/Bios/Processes and a fresh install of windows all accomplished little.

I had discovered this initial problem through GPU-Z, but just now realized that there are two fields labeled "Board Power Draw" and "PWR_SRC Power Draw" that are sitting idle at about 405-410W. The Board label is notably separate from the GPU Chip Power Draw, so it's probably the rest of the motherboard. Is there a sensor or something that could be fried and giving the wrong numbers? (For reference, it's a 230W charger and the power jack is rated for 330W max, so that draw is clearly incorrect. If the GPU is power throttling itself because of that, just have to figure out why it believes that) Given that that seems to be part of the GPU from my googling, maybe it is a motherboard replacement or new laptop time.
