How to Repair Laptop Batteries with Be2works31
Laptop batteries are essential for keeping your device running without a power outlet. However, over time, they can lose their capacity and performance due to aging, overcharging, or physical damage. If you have a laptop battery that is not holding a charge or showing incorrect information, you may be able to repair it with a software tool called Be2works31.
Be2works31 is a program that can read and write the data stored in the EEPROM chip of your laptop battery. The EEPROM chip contains information such as the battery model, manufacturer, serial number, full charge capacity, cycles count, and calibration data. By resetting or renewing the EEPROM data, you can restore your battery to its factory new condition and improve its lifespan and performance.
Be2works31 supports a lot of laptop batteries of different manufacturers and models. It works with Windows 8 or higher and requires a USB to SMBus adapter to connect your battery to your computer. You can download the full version of Be2works31 from their official website or try the demo version from here.
How to Use Be2works31
Before you use Be2works31, make sure you have the following:
A laptop battery that is compatible with Be2works31. You can check the list of supported chips on their website.
A USB to SMBus adapter that can connect your battery to your computer. You can buy one from here or use an EV2300 adapter from Texas Instruments.
A Windows 8 or higher computer with Be2works31 installed.
A soldering iron and some wires to connect the adapter to the battery terminals.
A multimeter to measure the voltage and current of your battery.
A spot welder to replace the cells of your battery if needed.
Once you have everything ready, follow these steps:
Open your laptop battery case and locate the EEPROM chip. It is usually a small black chip with 8 pins on one side. You may need to remove some tape or glue to access it.
Solder wires from the adapter to the EEPROM chip according to the pinout diagram on their website. Make sure you don't short any pins or damage the chip.
Connect the adapter to your computer via USB and launch Be2works31.
Click on "Read Battery Data" button and wait for the program to detect your battery information. You should see some data such as model, serial number, full charge capacity, cycles count, etc.
Click on "Read Chip" button and wait for the program to read the EEPROM data. You should see a hex dump of the data on the screen.
Click on "Reset (Calibrate)" button and wait for the program to reset or renew the EEPROM data. You should see a message saying "Chip reset successfully".
Click on "Write Chip" button and wait for the program to write the new data to the EEPROM chip. You should see a message saying "Chip write successfully".
Disconnect the adapter from your computer and desolder the wires from the EEPROM chip. Reassemble your battery case and test your battery with a multimeter or in your laptop.
Tips and Warnings
Here are some tips and warnings for using Be2works31:
Always backup your original EEPROM data before resetting or writing it. You can save it as a TXT or BIN file using Be2works31.
If you have a battery with integrated memory (such as BQ Z-series or BQ20xx chips), you need to read and write both Data Flash and EEPROM sections using Be2works31.
If you have a battery with M37512 chip (such as Dell or HP batteries), you need to use One-Push ec8f644aee
