The power adaptor seems in good condition. The problem persists regardless of whether the power supply is connected or not.
I pressed the shift+control+option+power key and the power lead connector birefly turned from orange to green. I then released all keys at the same time. I then pressed the power key and it powered up. The same problem occures:
It powers up, the screen goes white with the apple logo, the whirling timer icon spins away for about 2 mins then it shuts down. I was working perfectly prior to when I last shut it down...
The problem first occured while the power lead was connected. It is generally always connected so the power is generally full or close to it.
In regard to Option 1: I have now tried the shift+control+option+power reset with both the power connected and disconnected. The result is the same; when the power key is then subsequently pressed the machine does the same thing.
In regard to Option 2: Terry, you sound like you know your stuff and are quite expert. Now it's my turn to reveal my skills... I do not have the start up disk and do not know where it is. I hope it is in the office but I will have to have a good root around. I know they are important but I never think I will need them. So, I am the dummy in this deal.
I have the machelp order number.If I can find the disk then I will log back on and get further help along the lines you suggest.
If I cannot find the start up disk, what are my options? (Apart from buying new macbook pro and keeping the disk that comes with that!!)
Please advise, and accept my apologies for being beyond help!
Kind Regards.... Iain
Things have happened, but it dont look good.
Below is an exact copy of what now appears on the mac screen following the command: /sbin/fsck -fy
** root file system
** checking journaled HFS Plus volume
** checking events overflow file
** checking catalogue file
Invalid sibling link
** Rebuilding catalogue B-tree
** The volume Macintosh HD could not be repaired
/dev/rdiskos2 (hfs) EXITED WITHOUT SIGNAL
SORRY TO BE LONGWINDED, but thought this all might be important.
I have left it as is, just staring at me all angry ;o)
