Chuwi Gemibook keyboard blacklit issue

Dear Chuwi! I buy a Chuwi Gemibook, but the blacklit keyboard feíture doesn’t working normally…
When i turned on this feíture, it does working about 35-40 seconds, and it turns off itself…
Is it any solution for this problem? When will be corrected? Any BIOS update?

it is normal to save battery… with F5 you can switch on and off.

when i press F5 it only allows you to select between strong light and low light of the keyboard but it is not allwing you to turn light of the keyboard always on. are you sure that F5 allows you to have keyboard light always on?
