Solved! Keyboard backlight problem

[haziq.personal1]

Hello there, I have disassembled and assembled back my laptop: HP pavilion gaming 15-ak031tx, to clean the fan and heatsink. However, I found that left-hand-side of the keyboard (Qwerty keys) light was dimmer than the other side (The right numerical keys). The keys are still light up but not as brighter as before, very dim. I have no knowledge on this, can anyone please help me to solve this?

Many thanks.
