Multiple problems manifest at once after screen backlight repair
I had my MBP sent off to get the screen backlight fixed. I got it back yesterday and the backlight works. However, now I have a few new issues that have manifested.
1) No keyboard backlight. It was working before I sent the machine off. In fact, it was what made me realize that the machine was working instead of being completely dead when the backlight was out.
2) Black X over the battery icon. The battery was working just fine when I sent this machine off for repair. The battery stayed here at the house while the machine was being serviced.
3) The AirPort card is showing as not installed. I went into the logic board area and reseated the connector but that doesn't account for the other issues.
I'm hoping that there's a common component that could be causing all this problem.
So far, I have reset the PRAM (Control + Option + P + R on startup) and the PMU. I reseated the AirPort/iSight cable on the motherboard. None of this has had any effect.
