Got an interesting problem on a liquid-damaged MBP 13". This is the early-2011 i5 model w/ intel gfx. The display 'works' - as with most led issues, the panel is still producing graphics, just no light. However, when you first turn the machine on at boot - the LEDs come on, then 'gracefully' dim to zero as if to suggest software is dimming the LEDs, not hardware failure. Any ideas? The keyboard and trackpad appear to be destroyed. Works fine via usb, ordering new keyboard and trackpad.
