Yes, I have three laptops like that. And after a period of
non-connection/use, the BIOS settings on one of them were also
lost, eg the date/time and administrative password.

Have you checked the BIOS settings? Here for example is one PC's diary
record of me reconfiguring its BIOS when I acquired the machine.
Power Management
AC Recovery Power Off
Auto On Time disabled
Auto On Time 13:58 (ie PM)
Deep Sleep Control Enabled in S4 and S5 → Disabled
Fan Control Override disabled
USB Wake Support enabled → disabled
Wake on LAN/WLAN disabled → LAN Only
Block Sleep disabled → Block Sleep (S3 State)
Intel(R) Smart Connect Technology disabled
Cheers,
David.
