[SOLVED]820-3115 with battery wont power

[MDY]

-Only with AC adapter it works mostly. PPBUS - 12.56 when work. When wont power ppbus - 12.25V.

-Both battery and AC adapter - 12.25V

-Only battery - 12.19V

Should I replace first SMC or first ISL? As mostly wont power SMC first, right?

Could be corrosion under SMC, apply some flux and heat SMC...

 

[MDY]

Already did that. Doesnot help. Should be SMC or ISL but in such case what to replace first? Or it is 50-50%

Is battery recognized in OSX?

 

[MDY]

Yes, when work yes.

 

[dukefawks]

What when work? Does this sometimes not recognize the battery? Disconnect the battery indicator and try again.

I always work with only board in the table.
I replaced smc and now it powers always.
