Laptop loses sleep mode after a BIOS update

I have a Lenovo T14 Gen1 AMD laptop. Recently, I find my laptop has very high sleep power usage. Here you can see I disconnected the laptop from the charger at 11PM with 75% battery and 10 hours later there's only 35% left. I checked powercfg and found this. So I have lost all S states, and I also don't have hibernation? What system changes I did before this problem: I tried Lenovo's intelligent standby mode(it tries to bring the system into or out of hibernation based on daily usage pattern), then turned it off. Windows update(automatic) BIOS update(automatic) What's wrong here and how can I
