Share This Page Tweet. Anonymous September 3, at Bbq8030dbt i grabbed my trusty Fluke, and started to meassure voltages. Maybe someone knows smbus command to unlock charge? My second question is whether the firmware dump from that battery will be usefull for the new replacement chip BQ20Z90? I am programmer and I have done things in electronica, I have eeprom programmers, I would be grateful if you could tell me how to recover the firmware data.

There are resources out qb8030dbt but unfortunately I can’t help you with that, Google is your friend. Can you share your eeprom dump? Trademarks Privacy Policy Terms of Use. The EC manages the bus by itself and only provides an abstracted interface that’s accessible to drivers. BQ8030DBT BQ29330 Some experience with electronics and reverse engineering binary data files is required. You need to perform some hardwiring.

BQDBT Texas Instruments Ciiva Drew1Oct 3,in forum: Not sure if this is safer or more dangerous than a metal frame. Is the chip bricked now?

The newly bq8030dgt question will be automatically linked to this question. Mykolas June 24, at A little cyanoacrylic glue would fix things bq88030dbt after engineering the proper overload protection sense resistor my battery has been going strong since then. My laptop battery suddenly shuts off at about 42W of power consumption, or 3.

By looking at the sources it seems your code is pointing to device “0x04b4,0x”. Mateusz Grzywacz Bq8003dbt 27, at 1: When we find and clear the fail flag it sets the charging current and voltage in the SBS report to the normal values instead of 0 indicating that the pack is ready to take a charge. Nothing can be bq80030dbt from both as error is returned. You have to do something with cells, making them to have the same voltage, better bq8030dbbt replace with a new ones. Viktor December 12, at 1: So my guess is that one or more of the protection circuits have been tripped, and then doesnt want to go back to enable. Did you try running the tool as root to rule out permission issues?
