Plug the power adapter in. Then hold down the startup button for 15 seconds. The light should go off and then after a few seconds. restart normally. The macbooks have a safety device that will lock up the drive if it detects sudden movements to protect the drive...
Let me know if you're back up and running. KEN
Hello,
Please check your hard drive using your install DVD
Try holding down your power button until the unit turns completely off. Then try starting it back up.

no there is no boot chime. when i push the on button the screen flashes white for a split second then goes black and the white light stays on.
exactly the same problem what should i do ??? thanks
my problem is the same but the white light flashes like it's in sleeping mode, but it won't do anything. I've changed the logicboard in it which didn't help and i'm going to be installing a new LCD screen and if that works i'll let you know. I do know however that my problem was caused due to lightning frying something and that's of course not covered under my warranty so I have to try and fix it on my own so it'll be cheaper.
Mine does the same thing except it will make the little electric motor run over and over. I've found that by very slightly twisting the keyboard (power button corner to bottom left corner, and I mean like your going to fold it in half, but gently) it will them start. I'll let it boot all the way up and usually it's fine, but sometimes when I release the pressure it gets lines across the screen and locks up. Then all I can do is hold down the power button and try again. Once the thing gets good and warm there are no more problems (usually , anyway). Other times it will be working fine and just go blank and shut off, but the fan is still running. I know by having to twist it that it's a short somewhere but afraid to tear into it. I had to replace my hard drive about a year ago and this started a few months later. I did update to a bigger drive ( Hitachi?I think?)
Sometimes the only way I can get it to come on is to actually turn thr computer upside down and power it up that way. HELP!!!!!!!!!!!!!!!!!!! Please??? Anyone????
does the boot chime sound?
