Hello Everyboady
Working on 820-2914 with no backlight problem. Some one worked on this board before us and connected PBUS_S0_LCDBKLT_EN_DIV to direct ground so when machine turn on direct start LCD backlight and when sleep computer LCD backlight not turning off. ( but machine working normally)
I checked enable signal its 1.1V its too low. removed q9807 and R9840 its same value. This signal comes from u9600 but i want to ask , can i create fake Backlight enable signal for turn backlight on when machine working normal and turn off when computer sleep?
