WARNING: flashing the new BIOS can brick your laptop, DON'T do it if you don't know what you're doing or just for the sake of having the latest firmware. Make sure you actually need it and that both your laptop's power AC adapter is plugged in and the battery is fully charged.
If you've got one the ideapad gaming 3 laptops you might face the problem with updating the BIOS, if your model isn't covered via fwupd.
There are ways to workaround it with some crazy shit magic tools, but the safest way is just use the Windows environent in the absence of a BIOS update file for Linux.
