This thing gives me headache for quite a while now.
I have an Intel Advanced/ZP motherboard and everything is working fine except that it won't keep BIOS settings no matter what.
I have replaced coin cell battery, resetted CMOS with jumper and nothing.
I even replaced BIOS flash chip (in this case: using hot air reworking station) giving it proper programming before soldering it to the board. It booted but won't keep BIOS settings.
When I tried flashing new chip with Intel flashing tool it ended with failure.
That makes me think that maybe a component responsible for supplying proper voltage to the board is faulty, but I don't know which one is this and how to diagnose it.
Maybe some other component like eg. capacitor failed and stops battery voltage to reach BIOS chip (I checked some but found nothing).
Maybe it's one of the ICs.
I'm also not educated in electronics, but I can do simple stuff like taking measurements and soldering.
My motherboard is this one: https://theretroweb.com/motherboards/s/intel- … vanced-zp-zappa
I'd be glad for some advice on that.
