the system came initially with a nand short
On pp2v5_nand_ssd0, I cleared the short and restore with configurator2. It worked and sent out for deliver. After a week it was returned dead and I discovered another short on ppbus_g3h_ssd0_sns, I cleared it. Configurator2 successfully restored it ( the padlock logo came on the other laptop but the system in question has no display nothing. Still dead. Pls what to do

I also noticed PPVDDCPU_AWAKE is 0.55V and it's suppose to be more than that.

checked u7210, U7220, U7230 they all had there ppbus_hs_cpu voltages and pp5v_g3s voltages, cpucore_pwm1 was 0.2V and cpucore_fccm was 2.3V.
there were no voltages on the big coils and the cpu core too.
