Works with charger only

Does it show X on battery, or percentage?
Post F7000 voltage with charger only, and charger + battery.

Check resistance to ground on SCL/SDA lines of battery bus.

Other board installed shows same issue
shows battery 52% replace now

This sounds like a bunch of bad batteries....

 

[2informaticos]

I'm bit confused now...
Do you have two boards which report same issue with the same battery?
I doubt to be both boards bad; pretty sure battery issue.

 

[suzukigsxr1000r]

Have even 3 board installed and replaced 3 batteries so far
giving the same issue
replace now .
when disconnecting the charger it die right away .
could the battery cable the connecting the battery with motherboard do this !!!

If you have 3 MLBs, don't you have the original batteries for them?
These ones give the same error?
Or you get error only with "new" (fake) batteries?

I have one original battery and 2 replacements one
I get the error with all of them .
the main problem was non working keyboard
the laptop was working fine with its original battery .
( turns on with battery only but non of the keys worked )
there was corrosion on the touchpad cable which prevented the keyboard to work . Cleaned the touchpad cable and keyboard
works fine now .
connect everything back now not staying on without
charger pluggged .
Could be all bad Batteries.
or Fu***** hunted MacBook .

Trackpad (SMBus 3) and battery (SMBus 5) are connected on different I2C bus.
So shouldn't give conflict.
Unfortunately, theory and practice not always correspond...

Solved
needed OEM battery cable
thank you 2informaticos
