Why does my MacBook Pro (early 08 or late 07) have the black screen?
I have a Macbook Pro 15" non unibody (either late 07 or early 08) and it was working just fine, I had closed it and when I returned (about 2 mins later) I connected the charger and when I opened it, it no longer showed anything on screen. I thought the light was dim, so i tried to raise the brightness but nothing happened. I shut it down through the power button and when it booted the same thing happened - a black screen. I have done research on this topic and found a couple things.
-It could possibly be stuck in "clamshell mode"
-Possibly stuck in sleep mode
The fix for this is to reset the SMC and PRAM by pressing and holding a combination of keys on boot up. However, the keyboard doesnt work (caps lock light doesnt light up) only the power button works. The treackpad and button dont work either, and I had a mouse connected which also doesnt work because it doesnt get power. When I connect it the light at the bottom of the mouse lights up for a split second then turns off.
I dont think its the screen and have read that it may be the
-logic board or
-the graphic chip?
Is there any way to fix this?
Es esta una buena pregunta?
