celosam · #1 03-09-2009, 07:29 PM

Install iPC 10.5.6 on my LG R405A notebook:

CPU Core2Duo T5450 1.66GHz
RAM 2GB DDR2 667MHz
Video ATI x1250
Chipset ATI RS600M
WiFi Atheros AR5007EG
Lan Marvell 88E8039
Audio RTL ALC262

Everything is working fine. When removed the cable from the power supply, iPC system turned off the LCD backlight on a permanent way. Now i have to plug an external monitor and the LCD BACKLIGHT never worked. I have dual boot but on the Vista the LCD backlight also not working.

Anyone had this problem and help me please?
