Hp Mu06 Notebook Battery Pinout Configuration Link (No Sign-up)

The HP MU06 (also referenced as MU06, HSTNN-LB7N, HSTNN-LB7L, or TPN-Q188) is a standard 4-cell lithium-ion battery used in numerous HP notebooks, including the HP 240 G6/G7, HP 250 G6/G7, HP 255 G7, and HP 14s series. Unlike simpler 2-wire batteries, the MU06 uses a 9-pin or 11-pin edge connector with a SMBus (System Management Bus) for communication between the battery’s BMS (Battery Management System) and the laptop’s EC (Embedded Controller).

If you are troubleshooting a "Battery Not Detected," "Plugged In, Not Charging," or "Invalid Battery" error, understanding the pinout is your first step toward a fix. This article covers:

The HP MU06 typically uses a 6-pin or 8-pin connector, depending on the exact sub-model. While official HP documentation is not publicly available for this part, community-sourced and reverse-engineered pinouts suggest the following common configuration: hp mu06 notebook battery pinout configuration link

| Pin Number | Label/Function | Description |
|------------|----------------------|------------------------------------------|
| 1 | VCC (+) | Power output (connected to laptop) |
| 2 | GND (-) | Ground connection |
| 3 | SCL | SMBus clock line |
| 4 | SDA | SMBus data line |
| 5 | TEMP | Temperature sensor signal |
| 6 | CHG/ID | Charge enable or battery ID signal* |

Additional pins (7, 8) may exist for advanced features in specific variants. The HP MU06 (also referenced as MU06 ,

Below is the verified pinout for the HP MU06 9-pin variant. This is based on direct measurements and service manual cross-references for HP TPN-Q188 motherboards.

| Pin | Signal Name | Function | Typical Wire Color | |-----|---------------|---------------------------------------------------|--------------------| | 1 | B+ (Battery+) | Main positive terminal (8.4V – 12.6V, nominal 11.4V) | Red or Black | | 2 | B+ (Battery+) | Same as Pin 1 (current sharing) | Red or Black | | 3 | SCL | SMBus Clock Line (3.3V logic, 100 kHz) | White or Gray | | 4 | SDA | SMBus Data Line (3.3V logic) | Yellow or Blue | | 5 | SMBD_ALERT# | Battery alert (interrupt to EC) - open drain | Green or Orange | | 6 | PRES (or ID) | Battery presence detection (pulled low inside battery) | Brown | | 7 | THERM | Thermistor output (10k NTC to ground, ~1.5V at 25°C) | Violet | | 8 | B- (Ground) | Main negative terminal (0V) | Black (thick) | | 9 | B- (Ground) | Same as Pin 8 (current return) | Black (thick) | The HP MU06 typically uses a 6-pin or

Note for 11-pin versions:
Pins 10 and 11 are often not connected (NC) or used as additional presence detection. If your battery has 11 pins, ignore the extra pins – the first 9 pins match the above table.

When evaluating the HP MU06 notebook battery, consider the following:
