??But when I remove the battery COMS, whoring after
Working after you remove the CMOS battery? What is the voltage of this CMOS battery?
See attached. Locate the diode mated to the CMOS / RTC battery. Remove all power. Meter in DIODE mode. Connect the meter leads across this part. The meter should tone beep and conduct in one direction (not the boy band; be a value of 0.3 to 0.6 volts) and will block when the meter leads are reversed. Confirm that this diode is not leaking.

I removed all the power, first diode 0.3v. Second diod 0.2, resistor is ok, but with battery computer It gives 3.3 volts but when I put the battery coms/rtc it gives 2.8 voltsAttached FilesComment
