I find myself unable to change brightness suddenly

For context I game on a alienware laptop I recently purchased from a friend of mine. Everything is going great, no issues, but I will get the occasional black screen cus I am pretty sure the battery dies faster than it charges. It so far has not caused any issues with the laptop itself and I have done extensive digging to see if I can figure it out. But this second time, the slider for the brightness appears to have been greyed out. I have an alienware m15 r5 ryzen edition with a AMD Ryzen 9 5900HX with radeon graphics cpu, 32 GB memory, a PC711 NVME SK Hynix 1tb storage drive, a built in/integrated graphics card of a AMD Radeon TM graphics card, and a nvidia geforce RTX 3070 GPU.
