When the power supply is plugged in there is power on the motherboard but no lights at all. I have removed the battery, which seems dead as well.
I measure power on the section up to the first MOSfet switch which is turned off.
There is power to at least one pin on the OZ8681 charge controller chip. This is where I am stuck as I can not find a data sheet for this chip and see how it works.
Can anyone help pointing to spec sheet download. I have searched on the net for a couple of hours but admit defeat.
Anyone that can explain roughly how that chip works? Mainly need to know if the DC supllied to the chip sends DC power out in the form of the VDDA and VDDP port signals?
Still Trying to figure out how to attach circuit, my present laptop scrambles font when trying to browse for file.
