I have the same computer and my install of Leopard over my Tiger install is fine. My start up time is usually less than 30 seconds😕. Can't help you.
Did you archive and install? Maybe try a clean install of Leopard
If the power adapter is not plugged-in the processor may default to one core or reduced processor speed.
Also, if you take out the battery, the same thing.
This is not a Mac thing, its a laptop thing. My friends Dell does the same thing, but he runs at half speed if either is missing were are the Mac seems to do so only if the battery is out (except for boot up).
So all I can say is I believe its normal.
Has the "Mac OS X is starting up with the scrollbar" screen gone from the hard-disk/Intel version of Leopard? Its still there on my PPC iMac G5 (I know... and it is 15" too 🙂)
There simply is not one in 10.5 at all, Intel or PPC. Even my eMac @700MHz with 256MB of RAM does not have it.
My Boot up time is 2x Longer when I have a USB external HDD plugged in - Always.
I dunno why?
