power coming from m/b when no battery?
suddenly experiencing some wierd things with my motherboard..
firstly im running an opus 150w power supply..
turned the car off so (checked with multimeter) only constant power and ground is available. no accessories voltage is coming through.
put the plug in..and the psu starts up. (also a neon i have running).
check the pins of the psu and theres a small amount of voltage coming through the psu.. (like 0.4V).
so i take the motherboard battery out, disconnect all input devices (usb, monitor etc) and the voltage drops..(to like 0.05). now i put the power plug back in and it starts whirring again!
how is there power in the m/b with no 3V battery?
really really confused...please help.
(btw, checked on home pc with just power spply and same story happens..)
