Hp Mu06 Notebook Battery Pinout Configuration -
The HP MU06 battery uses a 5-pin connector (JST style, 1.25mm pitch). Looking at the battery connector (pins facing you, latch on top):
| Pin # | Signal | Voltage / Function | Wire Color (Typical) | | :--- | :--- | :--- | :--- | | 1 | B+ | Battery Positive (+11.4V to +12.6V) | Red or Black/Red stripe | | 2 | SMBC | System Management Bus (Clock) | White or Yellow | | 3 | SMBD | System Management Bus (Data) | Gray or Blue | | 4 | PRES | Presence Detect (Ground via 10kΩ resistor inside battery) | Orange or Brown | | 5 | B- | Battery Negative (Ground / 0V) | Black |
The HP MU06 battery follows a standard 7-pin SMBus configuration where Pins 1,2 = Ground; Pins 6,7 = Positive; Pin 5 = Presence Detect; Pins 3,4 = SMBus Clock/Data. The BMS implements strict safety and lockout features. Unauthorized cell replacement or improper voltage application on the SMBus lines will likely trigger a permanent failure lock. For reverse engineering or repair, always use an isolated SMBus adapter and monitor cell balance before attempting to reset the BMS.

typically features a 7-pin or 9-pin connector configuration. While HP does not always provide an official public pinout diagram, community data and technical teardowns indicate the standard layout used for these SMBus-based batteries. Standard HP MU06 Pinout (9-Pin Layout)
In many MU06 models, the connector uses 9 physical slots. For identification, hold the battery with the connector facing you and the label side up. The pins are generally numbered from left to right. Pin Number Description 1 - 2 Ground (-) Negative terminal/system ground. 3 SMBus Data (SDA) Communication line for battery data. 4 SMBus Clock (SCL) Timing line for data transfer. 5 Temperature (T) Thermistor pin to monitor battery heat. 6 System Present Often needs to be pulled to ground to enable the battery. 7 NC / Reserved Not connected or reserved for internal testing. 8 - 9 Positive (+) Main power output (typically 10.8V to 11.1V). Identification & Testing Tips
If your specific MU06 variant differs (some use a compact 7-pin layout), you can verify the pins using these methods:
Voltage Testing: Use a multimeter to find the outer pins. The pair showing roughly 10.8V - 11.1V is the Positive (+), while the opposite end with zero resistance to the case is Ground (-).
Communication Pins: The SMBus pins (Clock and Data) will typically show a logic-level voltage (often 3.3V) when the battery is active or connected to a charger.
Official Documentation: For specific part number variants, you can check for setup guides on the HP Support site.
Technical Discussions: For deeper troubleshooting or signal analysis, many users reference community guides on sites like EEVblog or KuzyaTech. Common Compatibility
The MU06 pinout is consistent across several HP and Compaq series, including: HP Pavilion: G4, G6, G7, DV6, DV7. Compaq Presario: CQ32, CQ42, CQ62. HP 2000 Series: Notebook PCs.

MU06 Pinout Configuration (9-Pin) No battery communication = No charge
Based on verified community posts from Laptopu.ro and technical discussions on EEVblog, the standard configuration for the MU06 (BQ20Z45/40 chip) is as follows: Pin Number 1 & 2 Ground (GND)
Often tied together; identified by measuring resistance to case ground. 3 SMBus Clock (SCL)
Communication line; typically pulses during laptop-battery handshake. 4 SMBus Data (SDA) Data line for status, capacity, and temperature info. 5 Thermistor (Temp) Battery temperature sensor for Super I/O monitoring. 6 System Present (SP)
Must be pulled to Ground to enable charging/discharging on some models. 7 NC / Reserved Often not connected or used for secondary control/ID. 8 & 9 Positive (BAT+)
The main power output pins; often tied together to handle current. Critical Technical Insights
System Present Pin (Pin 6): If you are testing this battery outside of a laptop, you may need to connect Pin 6 to Ground (Pin 1/2) to "wake up" the battery and see voltage on the positive pins. Safety Lock : Most MU06 batteries use Texas Instruments BQ20Z45
or BQ20Z40 chips. If the battery cells are deeply discharged (below ~3.0V), the BMS may enter a "Permanent Failure" (PF) state, which requires specialized software like the NLBA PC Software or a TI EV2300/2400 to reset.
Pin Orientation: When looking at the battery connector facing up (as it sits in the laptop), Pin 1 is usually on the left and Pin 9 on the right. Laptop battery pinout configurations - EEVblog
The HP MU06 is a 6-cell Lithium-ion battery utilizing a 7 or 8-pin connector with a standard Smart Battery System (SBS) layout, commonly providing 11.1V and 47-58Wh capacity. Key terminals include V+ (1-2), GND (7-8), and data lines for SMBus communication (3-4), requiring the System Present pin (5) to be grounded for output activation.

Understanding the pinout configuration of the HP MU06 notebook battery is essential for tasks like external charging, cell replacement, or resetting the internal battery management system (BMS). This common 6-cell battery is used in a wide range of HP Pavilion, Compaq, and Envy models. Pinout Configuration Overview
The MU06 battery typically utilizes an 8-pin connector. While official HP documentation rarely provides pinouts for consumer-level repair, community data and electrical testing define the standard 8-pin layout as follows: Pin 1: Ground (Negative / -) Pin 2: Ground (Negative / -) (Doubled for current handling) Pin 3: Unknown / NC (Often no connection)
Pin 4: System Present / ID (Sometimes needs to be pulled to ground to enable output) Pin 5: Clock (SCL) (SMBus/I2C communication) Pin 6: Data (SDA) (SMBus/I2C communication) Pin 7: Positive (V+ / +) (Output voltage) Pin 8: Positive (V+ / +) (Output voltage)
Note: On some variations, the numbering may be reversed depending on the orientation of the connector (left-to-right vs. right-to-left). Always use a multimeter to verify Ground (which will show 0 ohms to the battery's negative terminal) and Positive pins before applying power. Technical Specifications Battery Type: Lithium-ion (Li-ion)
Standard Voltage: 10.8V or 11.1V (depending on cell configuration) Capacity: Typically 47Wh to 55Wh for 6-cell versions The HP MU06 battery uses a 5-pin connector (JST style, 1
Chipset: Often uses the BQ20ZXX family (e.g., BQ20Z40), which utilizes the SMBus protocol for impedance tracking and state-of-charge calculation. Critical Maintenance Tips
Safety First: Lithium-ion batteries can be dangerous if short-circuited. Use insulated tools and avoid bridging the Positive and Ground pins.
Reprogramming: If you replace the cells, the BMS often locks the battery (Full Charge Capacity may appear as 0). Resetting this requires an EV2300/EV2400 adapter and specific software like BQEvsw to clear Permanent Failure (PF) bits.
Calibration: If your laptop shows incorrect percentages, you can perform a manual calibration by fully charging the battery, then discharging it completely through the HP PC Hardware Diagnostics (accessible via F2 at startup).
