With any mouse?
W83627EHG is tested on other mobo?
I took W83627EHG from working MOBO where was present +5V on MCLK.
then remove capacitor and test
Oscillograph?
Yes. With and without mouse present.
I took W83627EHG from working MOBO where was present +5V on MCLK.
I Tried that. In that case (without capacitor) voltage drops from 0.12V to 0.0V
No:(
