Looking again at Iain’s PC starting up by itself – Pt 3

03/03/21 – Iain said it wakened again at 19.43.

Downloaded logs and only suspect thing is in the System Log where the PC resumed from sleep at 19.43 on the 2nd (not 3rd) – no other logs then at 19.43 on the 3rd the PC changes the time. I understand that Windows may confirm the time from the BIOS clock/ Online then set its own time, BUT its a strange coincidence that the times are identical!
