Memory Upgrade Path
The Microsoft Surface Pro 6 has soldered LPDDR3 RAM (8GB or 16GB, fixed at purchase), which cannot be upgraded. Choose the capacity you need when buying.
Important: Since the RAM is not user-replaceable, we recommend opting for at least 16GB at purchase to ensure adequate performance for years to come.
Storage Expansion
The Microsoft Surface Pro 6 uses a BGA PCIe NVMe SSD (soldered) with a PCIe NVMe interface. There is no M.2 slot, so the SSD cannot be upgraded.
No replacement SSD fits: the Surface Pro 6 has no M.2 slot.
Note: the Surface Pro 6 SSD is soldered to the board and cannot be replaced.
Power Delivery & Charging
The Microsoft Surface Pro 6 uses a 44W Surface Connect charger. It has no USB-C port and charges only through Surface Connect, so USB-C PD chargers will not connect.
USB-C PD chargers: not compatible (no USB-C port).
Port & Docking Capabilities
Connectivity: 1x USB-A 3.0, Mini DisplayPort, microSDXC, 3.5mm, Surface Connect, Cover port
A USB-C hub such as the Anker 577 USB-C Hub will not connect, because the Surface Pro 6 has no USB-C port.
Upgrade Difficulty & Tools Required
The Microsoft Surface Pro 6 has a difficulty rating of 2/5 for upgrades (5 = easiest). The upgrade process is difficult — limited user-accessible components.
Tools needed:
- Phillips screwdriver (M2.5 or similar)
- Plastic spudger or pry tool (for bottom panel clips)
- ESD wrist strap (optional but recommended)
We recommend backing up your data and consulting the official service manual before opening the chassis.
