Tapndog, After updating the AMD processor we see you managed to get the backlight working. 
My laptop was received by Dell on 16 May. All I see is that the repair is taking longer than expected and that 'the estimated repair date has been updated' yet there is no way to find that date. Am I at the mercy of Dell or is there a way to find this 'estimated date'?
