The HP Pavilion G6 is arguably the most widely sold laptop series in Brazil between 2011 and 2014. The AMD variant (G6-1000 and G6-2000 series) in particular dominates repair shop queues to this day. With an AMD A-Series APU and the Radeon HD 7520G/7640G integrated graphics, it delivers decent everyday performance but suffers from heat-related failures at scale. This guide covers the AMD G6 motherboard, common defects, and repair solutions.
Technical Specifications (AMD Variants)
- Processor: AMD A4-4300M / A6-4400M / A8-4500M (Trinity APU)
- Chipset: AMD A70M FCH (Hudson-M3)
- RAM: Up to 8GB DDR3 1333/1600MHz (2 slots)
- Display: 15.6″ HD (1366×768)
- Graphics: AMD Radeon HD 7520G / 7640G (integrated in APU)
- Motherboard: DA0R22MB6D0 / DA0R22MB6D1 (HP spare: 647627-001)
- Storage: 500GB–750GB SATA HDD
- OS shipped: Windows 7 / Windows 8 Home
The Motherboard: DA0R22MB6D0
The DA0R22MB6D0 (revision D0) and its revision D1 sibling are the most common motherboards in the HP Pavilion G6 AMD series. HP spare numbers 647627-001 / 647627-501 / 647627-001 cover the most common variants. The APU is soldered directly to the board (BGA), which means APU failure = board replacement in most cases.

Most Common Failures
- No display after boot (APU failure): The AMD APU solder bumps crack under thermal stress, causing total loss of video signal. This is by far the most frequent board-level failure on the G6 AMD.
- No power / won’t turn on: Failed power controller IC or shorted MOSFETs near the charging circuit.
- Overheating and throttling: The APU thermal design requires a quality paste and a clean heatsink — the factory configuration deteriorates quickly.
- Charging not working: The HP G6 uses a proprietary charging circuit; a faulty charge controller IC (BQ24725 or similar) can prevent charging even when the adapter is good.
- BIOS locked / HP BIOS password: Very common after second-hand purchases. Requires a hardware unlock using a BIOS programmer.
Community Solutions
- APU reflow (no display fix): Heat the APU BGA area on the DA0R22MB6D0 board with a hot air station (200–220°C, slow approach). Apply fresh flux. This restores video temporarily but board replacement is the permanent fix.
- BIOS password removal: Use a CH341A programmer to read and clear the BIOS chip. The chip is a Winbond W25Q32 on most G6 boards. Replace the password hash bytes with 0xFF.
- Thermal maintenance: Disassemble quarterly in hot climates. Clean the fan heatsink and replace the thermal paste. Use MX-4 on the APU die and a thin layer on the GPU area.
- Charging fix: Measure voltage at the DC jack (19.5V for most HP adapters). If present but not charging, check the charge controller and the power path MOSFETs.
