Re: Cpu core voltage low

Thanks guys for your reply...!!!
Finally i decided to replace IC ISL 6262 as TH3_uN1Qu3 said.

and guess whattttttt...!!!! PROBLEM SOLVED.....!!!!!!MOTHERBOARD IS NOW BOOTING PROPERLY. THANKS ALOT....!!!

Re: Cpu core voltage low

Thanks pieron for your reply

i replaced vcore capacitors, i also replace smd caps in isl 6262 section , but same result....!
Cpu is onboard i can't change the cpu.

Voltages from vid0 to vid6 are 1011010

vcore voltage is still 0.7v,expected 0.9v to 1 v

dose cpu required any feedback signals?(cpuslp signal)

pltrst signal is prersent i measured it on sio pin 30.

Anyone have schematic for shb 110 motherboard?

Please guide me, what should i check further?
