Something is wrong with the on-board RTC - Real Time Clock.

You need to identify that chip or module and first see if its crystal
is damaged.

If the device is a Dallas TimeKeeper then you can simply plug in
another one, if soldered into the board then you have to decide how
much it is worth to fix...

The RTC is part of the 'Cougar Point Platform Controller Hub'

Clearing CMOS is apparently done by a jumper (G2101) RTCRST# (page 21 of
the schematic [1]. Power off then momentary short (p.163 of [2])


Hi Adrian,

That schematic and datasheet will be very helpful. Thanks!
