Laptop CPU suddenly limited to 10W and 1.6ghz frequency

[Cod3Me]

Tldr: laptop clocks seats at 1.61ghz no matter what happens and tdp can barely get past 11W

I have an HP laptop with an i5-10210u CPU. And for the past 6months of using it. I haven't had any issues with the CPU at all. Today I just decided to do some switch emulation again but the performance is just bad, tried different emulator, nothing. It's like there's literally no difference between been plugged in or not. I do a benchmark with throttlestop and the max power pulled why plugged in was 11.4W and 9.3W on battery. Mind you I usually went full 25w before now. The CPU doesn't seem to be thermal throttling at all and temp is max 72°c Prochot is 98°c. I tried changing power plans and it could get to 15.4W while plugged in, this only lasted for about a second. 15W was previously the limit when unplugged, but it doesn't even reach near that now.

I tried doing an Ac adapter and battery test from the BIOS, both pass and I'm stumped right now. Compressions that would normally take CPU utilization to 99 or 100 and raise the clocks up now sit at 76% and still 1.6ghz. From the Intel website it says that's the base frequency at 15w tdp. But task manager still says 2.1ghz.

Device info

Laptop HP ProBook 440 G7

Windows 10 pro 21H2

i5-10210u

16GB RAM.

Things I did lately, Update windows 10 to February cumulative BIOS update to 1.16.0.0 Intel graphics driver update.

Troubleshooting

HP support assistant says battery is fine and charging ok, BIOS tests passed Resetting power options doesn't help.

Please let me know what other info to provide and what steps to take. Thank you for your time.

Please help

Fixed, everything is fine now, I did a BIOS downgrade and everything is working properly now. Windows updated the BIOS but the issue is gone.
