Hello
I have a generic medion like laptop core i3 (Tcl rca is the brand) which shows 500mhz in bios at cpu speed.
I have received it with no power at all. Found it to be a mosfet in 19vol line close to the power jack and also a capacitor around the vcore which was shorted i think close to vcore power supply. I ve dound NO schematics fof it. It is a c14d motherboard rev2.
My Question is:
I ve placed a N channel mosfet 8A which is FDS884 to replace the 10A original which is SM4839 one and also placed a similar small capacitor in place instead of the broken shroted one which cannot measure or figure out what uf is it.
So my question would be can my new mosfet or the capacitor replacement be causing this 500mhz in bios? or maybe it was a problem before comming here?
Power adapter is original and same result if pluged to my lab power supply.
Thanks for any hint.
Original mosfet: SM4839
Replacement i put: FDS884
And here is the picture to the capacitor zone.
