820-3332 no power after changing palmrest

[Alan.L]

have i killed the PCH on this board? it had a bloated battery and the battery has been disconnected. i can power on with MagSafe 2 85w fine . so i took the board out then put in a good chassis with good battery. now it doesn't power up at all with battery nor charger.

PP1v05_PCH_VCCIO_S0 has 14 ohms to ground.

on a known good board it has 33 ohms to ground on PP1v05_PCH_VCCIO_S0
8

ppbus_g3h 12.57
PP3v42 - 3.4v
smc_bk_ACOK 3.3v
the resistance between 17/18 : 4.4 ohms and 27/28 22ohms
smc_lid 3.4v
no pm_slp_s4_l
no pp3v3_sus

Definitely using 85 watt magsafe 2 OEM? If in doubt, check PM_BATLOW_L

 

[Alan.L]

yes. i need a signature. i only used genuine lol

 

[Alan.L]

PM_BATLOW_L pulsed once to 0.6v then 0

Do you get PP5v_S5/PP3v3_S5?

 

[Alan.L]

Do you get PP5v_S5/PP3v3_S5?

yep

PP5v_S5 5v
PP3v3_S5 3.3

 

[Alan.L]

nevermind.

I've spent over an hour working on this board last night.

just then..I've tried plugging a MagSafe in this morning.
now it does fan spin
why?

 

[JohnB8812]

Sounds like you were trolled by bad charger or just a weird intermittent thing.

 

[Alan.L]

na i've two chargers on the desk. they work fine on similar board. i always like to compare measurements. you are right just a weird intermittent thing.
