Turns on, screen is black, turns off in 4 seconds.
So I searched around but couldn't find anyone with exactly the same problem as me...Most people's macs who turn on but the screen is black stay on, but mine doesn't. I've reset SMC, PRAM and done RAM test, ie taking each one out at a time and running it with each different one multiple times. When I turn it on, I hear the HDD start spinning, and fans, but then they all stop and it turns off. The magsafe adapter works and the battery charges. The screen stays completely black the whole time. Any help would be greatly appreciated.
Thanks,
John
Is this a good question?

Help us help you. The more complete the description of your problem is ( what OS you're using - 10.?? the history of when and how this problem originated) the more assistance we can provide, and, the sooner we can provide it.
Was the unit wet, dropped or did it suffer other physical damage?

Hi, sorry my opening description was so brief, I'll try and be more specific. I was using Mac OS 10.6. It happened when I left my mac on overnight, so the battery drained. I plugged it in in the morning and the aforementioned symptoms occurred. Then, I left it plugged in for most of the day, and it turned on like normal. After I turned it off this time, to prevent drain, it refused to start again. I have repeated my original fix of charging it up and it has not worked. The battery does charge, as the battery indicator lights went from half on to all on, and the magsafe power adapter is orange when plugged in. It once had liquid spilled on the keyboard, years ago, as well as being dropped, again, years ago, both with no symptoms at the time. Please let me know if there's anything else you need to know or I need to do!
