A3401 battery not recognized

[hgoncalves]

Hi.

I have an A3401 with liquid contacta, and now it doen't recognize the battery.

I can't see nothing damaged on the board, nor even liquid signs.

Can you help?

Do you have the boardview and schematics for this model?

Hi, sorry.

Check diode mode and voltage on battery SMBUS lines.

I can't find the boardview or schematics. Do you have them and if so can you share them with me?

Hi.

Tks for the file.

The board is different from the file.

The battery is shown on the System Information, it shows the cycle count, but no state of chargeprecentage.

The battery percentage stays allways at 1% and the mac says service Recomended.

Do you have the schematics, or do you have any idea of where should I start?

P.S. Cliente says it might have catch come humidity on the plane because it was on a backpack wtih a water bottle (but she saw no liquid on the mac).

Can you help?

You should test with known good battery first.

Hi.

I can't find a new battery anywhere.

Do you know a trustable seller?
