Long back I've written some thing about Mac I researched a lot on the most talked about problem of the Mac users and I found out that most of the Mac users are facing the problem of black screen at the time of start up.
Most of the time such a problem occurs when we leave our Mac book untouched for a longer duration of time. Its not a regular feature. What I found out, as per my research was, the main cause of such a problem to occur is of corrupted sleep image.
The procedure I followed to delete the corrupted sleep image is:
1)I started my mac in target disk mode.
2)Connected another working Mac via fire wire.
3)Upon starting the working Mac, started the effected Mac book pro too
4)While the effected mac is starting up hold on to the “T” key
5)You will find a external hard drive in the finder
6)Next step is to open the finder in the working mac book pro
7)You will see the effected mac book pro name in the finder
8)Then simultaneously press CMD+Shift+G
9)Type /volumes/name of effected computer/private/var/vm/
10)Delete the sleep image from there
11)Empty Trash.
12)Eject the effected mac
13)Remove the fire wire cable
If every thing goes as per the plan your mac book pro will work fine. But, the most important thing which I would like to mention is to back up your data as soon as the systems starts working fine. Another most important thing is to disable the sleep mode via preference pane, which I forgot to do and lost the data when I was trying to recover from the same problem again. I had to buy a third party mac data recovery software to recover the data.
