I got this MacBook Air 820-3437
Came in dead. Does not have S0 Enables. So i measure diode mode on pin4 on U8180 and it is low (around 0.065V). I injected voltage on PM_SLP_S3_BUF_L. But nothing gets hot and current draw is low (around 0.1A)
Computer is working if i force S0 state by bridging pin4+5 on U8180 but then of course doesn't sleep very well...
Any tips to find out what is causing the low voltage drop on PM_SLP_S3_BUF_L and P5VS0_EN?
Thanks
