Mar T,
While I appreciate your answers the one thing you have not clearly stated is that there is no internal battery for the clock. I'm good with there not being an internal battery, but it is something that should be explicit so as to minimize the surprise when
the clock time does not match up with the time you are expecting.
Yes, there is an internal battery. That is the one that powers the SP3.
No, there is no internal clock battery (at least that is what I am understanding reading between your lines). The system clock relies on the internal battery of the SP3. The fact that there is internal functionality to prevent incorrect system times doesn't
change that and means that on occasion the clock has to manually corrected.
With all that said, I really like my SP3. All I wanted was to have confirmation that there was no internal system clock battery. The 2 times that the clock was wrong seemed weird given standard PC behavior.
Thank you for taking the time to discuss this! :)
