My brother gifted me PowerBook G4 laptop and its real fun having it with me. I keep on using it the whole day and you know it never created any sort of problem until I did any kind of modification in it. Recently I upgraded the Mac OSX 10.5.8 and I think the upgrade didn’t suit the system resulting in some weird kind of issue all the time. However after I did the upgrade I found that the backlit keyboard was not functioning. Tried all the possible solutions give to me till now but none of them worked. Instead I can say that as much as I try different solutions I make myself sure that the problem is becoming too serious.
Let me tell you that i have already checked certain thing in my machine and made sure that there is nothing into the system that has disabled the backlit function. The keyboard has not be turned off thought f8 key neither the F8 is toggle to ON or OFF nor F9 & F10 are increased or decreased. Overall I just need to say that I have already tried out all these three button combination and also other possible solution given to me (I can’t paste those suggestion give to me as they are too large to be pasted here… ), I am sure that the backlit keyboard is still working. Reason for being so sure is that the number lock and the caps lock buttons are still working well and fine. I strongly doubt that there is something that has been crashed after I did the upgrade to Leopard. But confused due to multiple thought, please help me out and clear my doubts, is that my backlit keyboard working properly or do I need to take it to the care center for the repair?
