Hi.

Was the battery purchased from a reliable source? The details seem to hint there is something is wrong with the logic board.

Post the full markings on the batteries. Maybe the batteries are not compatible with this unit ?

Did the original battery ever work with this computer?

What is the history? Any liquid damage?

Do you have test equipment like tools, soldering iron, multimeter?

I dont know if the battery ever works with computer. I bought the laptop with the water damage. I only replace the keyboard and all works fine. But battery has this defect, i think its bad battery.
I repairing laptops, but i am beginner. Maybe i think its defect from "logical"(charging) chip for battery on motherboard?
I have no problem with replace the chip, but i dont know if its that problem.

And battery is from Aliexpress, but they say its original and looks at original.

Are you using Lenovo Energy Management software,if you are check the settings. Have you checked the battery with Lenovo Diagnostics

"original", "new" and "Aliexpress" never go together very well.

Lenovo energy manager shows the battery is in good condition.
Calibrate battery with energy manager goes well from 100 to 0%.
Any idea? Before i bought new battery?
