Longer boot up with no chime after hard drive replacement.
I recently had my late 2009 27" iMac repaired by Apple because of a hard drive failure. But i noticed that it now takes a little bit longer to boot up and there isn't the usual chime when it starts up, the difference in time is only maybe 20 seconds longer than it used to be, it's not a major problem really but i'd just like to make sure it's running ok.
Once up and running it works fine, nothing different with the performance at all.
When it was fixed it did need to have the rear housing replaced, i'm not sure why though. And the power cable now doesn't push all the way in, which doesn't seem to cause any power problems.
I also ran the AHT and that said there wasn't any problems.
Is there anything i should be worrying about? Because as i said, it's fine once it's up and running.
Thanks in advance.
iMac, Mac OS X (10.6.8)
