Throttlestop stops working when it is not plugged in

I have Lenovo L340 gaming laptop and I have been using Throttlestop since I bought the laptop to increase the time when the laptop is not plugged in. Since last month, Throttlestop stopped working while it is using battery. When it is plugged in, there is no problem. But while it is using battery, the frequency does change between 3000-1000 Mhz rapidly (I have 2 modes on throttlestop. While I am playing games, the frequency is about 2700 mHz. While I am using battery mode, it goes around 900 mHz.). The frequency goes up to 3000 mHz and it goes down to 1000 mHz in one second. After that, it goes up 3000 mHz again and this process repeats again and again. But there is not an issue while it is plugged in. The values are stable and it fits the expectations. So Throttlestop modes does not effect the frequency while it is not plugged in. I will leave my Throttlestop settings in case I am doing something wrong. I hope you can help me to solve this.

Do not use ThrottleStop 9.0.
Use version 9.4 or 9.4.2


ThrottleStop stopped working
If ThrottleStop does not work the same, it is because Lenovo released a BIOS update. This update changed how Speed Shift works. ThrottleStop is the same but your computer is different.

After the update, setting Speed Shift EPP to 255 does not work the same. There is no way for me to fix this. Installing an older BIOS version might fix this.

The FIVR - monitoring table shows that 255 is still being sent to the EPP register but the CPU no longer works the same.
