My 7300/180 does exactly the same thing.  I even tried swapping memory
and replacing the onboard battery, neither of which changed the
behavior.

I suspect there's just some component in the power supply that gets old
and takes more time to come up to operating spec than the machine allows,
so it doesn't come up on the first try.
