Re: HP EliteBook 850 G1
Well i set bios to power on machine at a specific time and it did.
I found a schematic.
I have found,
Power button
Lid Switch
Power LED
All don't work.
Page 62 of HP ElitBook_840_G1_6050A2559101.pdf Is the board.

Re: HP EliteBook 850 G1
Tried new CMOS battery.
Tried without HDD.
Updated BIOS to newest.
Tried with only power adapter.
I don't think any rails apart from cmos sram will be powered from cmos battery.
I just don't get why cmos has to be cleared for it to turn on.
unless on power off it enters some weird state.Leave a comment:

Does not power on after shutdown.
Unless all power is removed beforehand.
Cmos battery is removed.
Battery is removed.
Power adapter is unplugged.
Once done

Main Battery
Power Adapter at this step system will power on complain about cmos reboot and boot into windows.
If restarted will work normally.
If shutdown/powered off will not power back on. unless above steps are done. -

Re: USB powered relay for mains voltage?
Very easy.
U will need a 5v relay that is sutibale to switch mains,
a diode,
a usb cord,
wire sutiable for mains,
Mains Plug and socket,
A case to hold relay and connections.
Two cable grips to fit the enclosure.
Good wiring practices and the relay provides the isolation.Leave a comment:
