Dell Vostro 14 3405 (Ryzen 5 3500U) - Unlock power limit request

Hello everyone! As you can see in the title, my laptop has limited performance. Specifically, I played games on this laptop very smoothly at first, but after a few minutes it suddenly lagged. At that time, I didn’t know why. I tried everything possible, such as turning on everything in performance mode, but it was still the same. When I used msi afterburner, I saw that at first it was smooth, the clock speed was still very high and the machine’s temperature gradually increased. But at around 80°, the machine started to drop the clock speed and the fps started to decrease. The temperature from then on dropped to 57-60° (because I used an external heatsink). After further investigation, I found out that it was my bios that limited it and I started thinking about mod bios. But this was the first time I thought about this and through research, it was quite risky. So I came to this forum because I know there are many experienced experts in mod bios here. I hope everyone will help me!

Thank you to read this!
