Hello everyone,
I have an Acer Aspire with an AS07B61 battery. This battery is no longer working, so I disassembled it and discovered that it consists of six 18650 cells. I tried replacing them, but the BMS detects that they are not the original ones and goes into lock mode.

I then thought about resetting the chip values so that it would accept the new cells. The chip is a [B]bq20z955[/B], so I tried accessing it using an [B]EV2400[/B] and [B]bqStudio[/B], but it is not recognized.

Can anyone help me? How can I reset the values? I suspect that it doesn't appear...
