A1286 won't turn on - black screen, have reset SMC, power light on
- MacBook Pro A1286. Removable battery and hard drive.
- Battery charges fine. LED indicators show charge level. Power adaptor shows orange when charging, green when charged.
- When turning on, power LED lights up, the chime can be heard, but nothing on the screen (no flashes, etc.). Keyboard backlight does not light up; caps lock key does not light up when pressed.
What I've tried:
- Have reset SMC with and without taking the battery out first; charging cable responds with green light
- Have tried holding Command-Option-P-R startup as suggested in another thread
- Have plugged a HDMI cable in to a TV, but nothing shows
Can you tell us what happened to the system beforehand.

Hi Dan. It's my friend's MacBook, and he says nothing happened to it.
