Yes, I think that is substantially correct.  I am not sure how many
times I tried before I was able to boot successfully.

I do have at least one intermittent problem, not related to booting.
One of the three USB ports works sometimes, but not all the time.  I
plug my wireless mouse transmitter/receiver (WTR) into the USB port on
the left, and sometimes it works, sometimes not.  On the other hand, if
I plug a USB extension cable into that port, and plug the WTR into that
cable, once it works properly it will continue to do so regardless of
how frequently I remove and re-insert the WTR into the extension cable.
Obviously there is a problem with the USB port, rather than the WTR.

Another possibility is that the problem may be related to moving the
laptop (transporting it) with something loose inside.  Yesterday I had
to try several times to get it to boot properly (the screen gave a very
interesting 'Northern Lights' imitation each time, but eventually it
booted properly.  On the other hand, today I have booted a number of
times with no problem -reducing the probability that it is heat related.
Thanks for keeping the problem in mind, though.  The system was a
'refurbished' one from Staples two years ago, and I did not purchase an
extended warranty.  Penny wise, pound foolish?  Perhaps.
