Startup pauses with "No parking" sign after 2 min.
Trying to start up from internal or external HD is not successful. Apple sign and clock appear, but after 2 min. give way to the road sign "No parking". When I have erased and restored, the machine has started up just once after that, both times. The internal drive is 3 years and the external two months. I have changed the PRAM battery, but after 12 hrs machine still does not start. The machine runs from a system CD which I have used for restoring or in FireWire mode. What can I do? (Thanks for a good guide to make a quick replacement of the PRAM battery you sent.) Model is A1151.
Is this a good question?
