No luck so far with FoxConn, but if you want a laugh, I pulled the 'new' CMOS battery to check, and it was ............2.8V (not sure how that happened!!), so I might just stick where I am and see how a new 3.3 does. Sorree! Sometimes the simplest thing, as Occam once said:ugh:

Belarc Advisor might give you the info you need without having to take the cover off.

LFAJ - yes, thanks - I use that but it did not offer anything new.

Tedious, I know, but after 8 or 9 'successful' boots with the extra 0.5V in the system, and thinking all was well, I had another CMOS reversion to default this am. I guess I'll have to pull the battery and check the volts again - maybe there is a short somewhere.

That battery is a CR2032 I presume?
Just a chance a CR2028 or CR2024 may have been fitted in error - and being slimmer they can rattle about and come loose
Has to be a CR2032

2032. I have not got round to checking the volts on this one yet. It is possible I put in a duff battery OR there is some sort of short, maybe.
