ive got a sony cr21s installed with ipc 10.5.6. ive got the x3100 driver beng recognised and shown under system profiler. but no hardware accelator.

ive found the fix for the max brightness problem. ive put a dsdt.aml file into the mac root. and now i can turn the brightness up and down. but the problem is that my laptop screen keeps turning off. and i have force sleep mode through power button + s or close the lid, which then turns the screen back on

does anyone know what to do
