    How to repair a laptop battery (chip reset)

    Hello everyone,

    In the last 10 years, I have dedicated a good period to create a device to analyze and repair laptop batteries. Since this domain is a top-secret domain with poor information on the internet on how a laptop battery works, what is inside, what is the chip doing, how to reset, etc., I decided to create a topic where I can answer your questions, of course, if there is interest.

    If the moderators think that it is not fine to have it then no problem.

    Re: How to repair a laptop battery (chip reset)

    can it be modified to use for other battery packs like say 80v power tool ones ?

        No. The gas gauge chip used inside the laptop batteries (typically TI BQ family) is designed for 1s to 4s, max 5s for drone batteries.

              Great idea. I just started to work on arduino project for communicating with laptop battery via i2c. For start my plan is to go with BQ series ic and extend it for more during the time.

                There are analyzer devices and software that can be used for battery repair. Professional repairmen are also available. The program chip in the battery can be rearranged by connection via USB.

                In fact, it communicates with the IO chip, battery inside the notebook via I2C. windows user should be able to access this information with an application. I need a program.

                  There are 2-3 softwares, just softwares that cost from 350$ worst one to 1000$ a good one. No support included, actually no English to poor English.
                  Maybe you know another device/product, just paste it here.

                  Using a Windows program you have access only to the SBS standard commands like reading few information CycleCount, ManufacturerDate, ManufacturerName, FCC, etc. But you won't have access to the SMBus routines to send any command like Unsealing the chip or programming it.

                    There are already libraries for Arduino that can read laptop battery information over I2C. Note that the communication protocol is SMBus, it is very similar to I2C but there are still differences. You can read more chips, not just BQ family. My question is, what do you plan to do ? just reading the parameters ?

                                    Hello, first of all, excuse me, I am using the translator, English is not my native language.

                                    I have a Lenovo ideapad 330S - 14IKB laptop.



                                    The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

                                    Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                                    by Bowline
                                    My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                                    Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                                    My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                                    The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                                    I have tried multiple different Dell power adapters. My Dell...

                                    The laptop is working fine on adapter and battery is also charging and when adapter is disconnected in on state the laptop gives backup on battery and gives good backup.
                                    But when laptop is powered on through battery only the laptop does not power on and there is 0 voltage on battery connector.
                                    I have not not tried another battery as it is not available locally could this be a battery problem.have checked discharging mosfet and there is no shorting to ground on any pin of battery connector.
