HP Omen 15 (2021) Suddenly dropping cpu speeds while plugged in but on battery is stable.

[Kodomine1]

My laptop has been working good for over a year, but iver the past month it has experienced this sudden episodes of lag accompanied by drops in cpu clock speeds but when not plugged in, these problems stabilize at the cost of performance. I have tried many common fixes, edits to power plans, reinstalling windows, updates to BIOS, but now I suspect an ac adapter issue? If so where can even get a replacement in the Philippines? This has been driving me up the wall, please help.
