Why is my laptop's graphics performance going down when it is connected with AC power?

1

My HP Omen (Windows 10, Core i7 7th gen, 16GB RAM, Nvidia GeForce GTX 1060 6GB) was so far working great to render even high-end games and applications on high FPS. But now, I am facing problem even with moderate level games and applications.

Before anyone can think of damaged hardware because of heat, let me tell you the peculiarity of the problem: I am experiencing this problem only when the laptop is connected with AC power, not on battery. It's quite opposite of what I expected. It's bad for me because running a high end game and application on battery drains the battery fast.

I have already checked the power options and all graphics options. Graphics card isn't being throttled down when on AC power.

What's actually happening? How to fix this?

How are you actually measuring performance? You should try Unigine Heaven(or other) and give the data of the benchmark. – dmb – 2018-02-08T21:08:54.403

I don't have experience with HP laptops, but with Dell laptops, if you're using an underpowered AC adapter, the system will throttle down, even with a full battery charge.

Are you using the original AC Adapter? Do you have a 2nd AC adapter to try? It's possible that your AC Adapter isn't putting out the full amperage needed.

Looks like my adapter got damaged by over voltage or something. I used adapter of my old laptop and problem is gone. Thanks. – Apple II – 2018-02-08T23:21:09.357
