Original problem
Our friend AG has a MacBook, ~2007, that didn't turn on. Battery didn't charge. Screen was black.
Stage 2 symptoms
After I removed the memory.
- Screen only flashes for a millisecond at power on, then stays black.
- Caps lock, num lock keys don't light.
- No power to ethernet port.
- Nothing on external video port.
- Not responding to lid closing. Sleep indicator not coming on, HD still spinning.
- Will force-shutdown, but turns on again immediately. Can force-shutdown by holding power key.
Current status
After I replaced the extra memory, noticing how hard it was to jam them in all the way. Maybe the memory wasn't seated well before?
- Startup chime.
- Goes to login panel.
- Caps key works.
- A bit slow while Finder and Safari (automatically) launch.
- 'C' during startup starts from DVD.
Steps to recovery
- Reset PRAM
- not helping, since power button doesn't work.
- Attach external keyboard, press power
- Not working.
- Resetting SMC by detaching battery, detaching power, pressing power button for 5 s
- Nothing.
- Removing extra memory
- Yay! Well, something, since now the power button is responsive, but not the rest of the keyboard. Caps lock isn't working, FireWire Target Mode isn't. PRAM reset is now working, but not helping.
- Starting with Leopard install DVD
- Disk taken in, spun, but not much action. At least none on the screen
- Attach an external monitor
- No response.
- Try caps lock key
- No light on key.
- Attach external keyboard again, see if key combos like PRAM zap or Target Disk Mode work
Next steps
- Jiggle cords
- Requires going further into innards.
