Right... I guess it would be easier if it had fell off :-) Oh well.
As a test, you could stick another cap in parallel with the flying one
and see if it helps. - end of cap would go on left, which is 0V.
I'm measuring the voltage at the right end of the VB_SYS cap with a
voltmeter (I'm at home, so don't have a scope handy). It seems to be
fluctuating between 3.7ish volts and 5V. Does that give any clue?
Any other test points under the can that I should check?
