    I was given an A1181 white MacBook by a teacher to fix. It refuses to boot.

    Here's what she told me:
    1. The battery and MagSafe cable went wrong in 2010 and were replaced by Apple.
    2. The hard drive died recently and was replaced by her husband.
    3. The recovery disk got stuck in the drive.
    4. She used to see the flashing question mark at boot, now nothing.

    Keeping that in mind, I let the MacBook charge overnight and hoped this would be something simple. I turned it on...
    1. There was no light at the front.
    2. I could hear the disk drive, HD, and fan at high load.
    3. The screen flashed white.

    Here's what I thought:
    1. The disk drive may be causing problems.
    2. The screen backlight is dead.
    3. The logic board is bad.

    Here's what I did:
    1. I opened the case and took out the battery, HD, and disk drive.
    2. I plugged in the charger and turned it on.
    3. I put a lamp behind the Apple logo on the top case.

    New thoughts:
    1. The LCD is causing problems.
    2. The logic board is dead.

    I asked the teacher to bring her mDVI adapter. If it works on my ACD, then I'll know it's down to the graphics or LCD. If it doesn't work, then the logic board is bad. A replacement logic board would be worth more than the MacBook itself.

    What are your thoughts on this? Thanks a bunch!

    These White MacBooks are known for being quite picky with RAM. When RAM is bad or about to go bad, it tends to now give the 3x beep RAM signal at bootup but show other flaws. Can you remove the RAM and see if it's giving the 3x beep signal?

    If it does, it might be that the ram is bad!

    I'm not getting any sign of life from the MacBook, other than the white flash and fan.I took out the RAM, but I didn't hear any beeps.

    Thanks for the response!
