Laptop Battery Electronics 'Reset' FAQ

Can't the device be locked? Where can I find the data and clock line settings?

There are no line settings, the software is a brick, rip the 24c02 memory and paste it here, to do a reading you need power from all the cells that are working. Paste correct good pictures of the PCB on both sides with the circuits visible.

...Paste correct good pictures of the PCB on both sides with the circuits visible...
I support this. pavelicom, please insert good images of the board.
Scan it on a high-resolution scanner from both sides. And upload detailed images here.

...Can't the device be locked? Where can I find the data and clock line settings?...
The device cannot be locked for reading the standard SBS report.
Reading EEPROM through the bq2060 is possible, but only if there is no lock flag in the EEPROM.
It can only be removed by reprogramming the EEPROM directly by connecting to its Gnd, SDA, and SCL lines.
There is no need to even remove the EEPROM from the board. Just solder onto the 3 pins of the chip.

P.S.
Did you 'wake' the controller after connecting to the battery cells?
This is necessary to do; otherwise, the chip is in sleep mode and will not respond to requests on the bus.
To wake it up, briefly connect the maximum '+' of the battery cell assembly to the '+' terminal on output the board of controller for 2 seconds (highlighted in red).

If this is station RF13.1, it does not indicate anywhere that it has the capability to communicate with the charger via diagnostic circuits, as with RF13.13.
In other words, even if a bq2060 is actually present, it is still unknown how the SMBC and SMBD circuits of the controller are connected.
Which of the two models is shown in your post? RF13.1 or RF13.13?
And what hardware do you actually have? This may also be important.

in my post there is a battery RF13.13. Batteries up to RF13.1 can also communicate with the charger. I have EV2200 hardware and EV2200-60 software

So, have you found the problem? Is there communication with bq2060 via SMBC and SMBD?

I haven't found the problem yet. I'll try activating the battery with a charger. Maybe it's because the electronics are in sleep mode.

I connected the power supply to the charger. This should probably activate the electronics. I still couldn't connect to the EV2200. If there is no error in the EV2200. There is 5V voltage on the EV2200 terminal, so the power goes there. Between GND and SMBD, SMBC there is about 3.5-4V. I don't know if just the EV2200 itself should connect to the PC even without the electronics connected. The program writes these two messages in the lower left corner. According to the photos on the Internet, there should be an RS-232 interface OK, but it never shows up for me.

Something is wrong, the battery wakes up when power is applied to it, this circuit is very simple. You may have the smbc/smbd lines incorrectly connected or the port selected incorrectly on your system. It worked fine for me but that was back in the Win XP days.

On my Win7 x86, the battery on the bq2060 is read perfectly using the ev2200-60 software.
In the options menu, select the COM port to which the ev2200 is connected.
The port must be a hardware port, meaning it cannot be a usb-to-com converter.
Judging by the picture, the program detects the ev2200 board, but there is no response specifically from the battery.
However, please check the connection of the board and the communication between the program and the board, as I indicated above.

The text "RS-232 interface OK" only appears when there is a connection to the ev2200 and a connection to the bq2060 battery controller at the same time.
