Add from both the SDA and SCL lines to a 3.3V power source, as the SMBus protocol requires pull-ups to transmit data cleanly. Safety Warning
The HP MU06 battery typically features a (depending on the specific revision), though the functional layout remains largely consistent across the series. Pin Number Function Description Pin 1 (+) Positive Output / Charge Input (Voltage Rail) Pin 2 (+)
Pins 5 and 6 are the most critical for smart battery functionality, carrying SMBus (System Management Bus) communication lines. Pin 5 is the clock line (SCL), while Pin 6 is the data line (SDA).
With Pin 5 successfully jumped to Ground, place your multimeter probes back onto and Pin 7 (-) . You should now read the true voltage of the battery pack (somewhere between 9.6V when completely discharged to 12.6V when fully charged). Safety and Precautionary Guidelines
The communication is handled by a specialized "fuel gauge" or "battery management" chip. For the MU06, this chip has been identified as the or BQ20Z40 chip. The BQ20Zxx series uses the Texas Instruments Impedance Track™ technology for accurate battery monitoring and also handles safety functions like overvoltage and overcurrent protection.
: Many MU06 batteries utilize the Texas Instruments BQ20Z40 or BQ20Z45 gas gauge chip. This chip monitors cell health and can "lock" the battery (Permanent Failure bit) if it detects cell imbalance or extreme depletion.
The internal BMS has tripped a permanent failure flag (UVLO - Under-Voltage Lockout) due to dead cells or a short circuit. The pack is dead and unsafe to use. Safety Guidelines and Warning
This guide provides a comprehensive breakdown of the HP MU06 notebook battery pinout configuration, its smart battery interface, and safety protocols. Hardware Specifications Overview

Connecting to a laptop battery requires precision. Standard batteries do not simply output raw voltage; they use a sophisticated Battery Management System (BMS) that communicates with the laptop via a specific communication protocol.
