General

• Model: Lenovo ThinkPad P50s (15.6″ mobile workstation class).

• Form factor: 15.6″ laptop, “slim workstation” design.

• Build & durability: Typical ThinkPad business-build, MIL-STD tested as per P-series.

Processor / Graphics

• CPU: 6th Generation Intel Core i7 (e.g., i7-6500U 2.5GHz base, up to ~3.1GHz) for dual-core/4-thread.

• Discrete GPU: NVIDIA Quadro M500M (2 GB dedicated graphics memory) for professional-graphics workloads.

• Integrated graphics: Intel HD Graphics 520 (for switching depending on use).

Display

• Size: 15.6″ diagonal.

• Resolution: Commonly Full HD (1920 × 1080) IPS panel; higher resolution options may exist.

• Surface: Business-style anti-glare matte finish (in many configurations).

Memory (RAM)

• Your spec: 16 GB RAM.

• Channels / slots: Two SO-DIMM slots. According to specs the P50s supports up to 32 GB RAM

• Type: DDR3L SDRAM (1600 MHz) in many configurations.
  Upgrade Info – RAM: Yes — RAM is upgradeable (because it uses two SO-DIMM slots, not fully soldered).

Storage

• Your spec: 256 GB SSD.

• The platform supports SSDs (and other forms of storage) — e.g., some variants list up to 2TB SSD support.
  Upgrade Info – Storage: Yes — storage is upgradeable, you can replace or upgrade the SSD.

Connectivity & Ports

• USB ports: Multiple USB 3.0 ports (typical).

• Display outputs: Includes HDMI, mini-DisplayPort, possibly docking connector.

• Network: Gigabit Ethernet, WiFi ac + Bluetooth.

• Card reader: 4-in-1 card reader in many configurations.

Battery & Power

• Battery life: Varies by config and load; reviews note that it is solid for mobile workstation class but with heavier loads battery will drop.

• Power adapter: Typical business-workstation adapter (e.g., 65 W or more).

Features & Business Class

• Keyboard: Typical ThinkPad business keyboard with TrackPoint and back-lighting (depending on config).

• Security: Fingerprint reader, TPM, business security features.

• Certifications: ISV certified for professional apps (CAD, engineering) in the P-series line.

Strengths & Constraints

• Strengths: Good balance of workstation-class GPU (Quadro), upgradeability (RAM/SSD), durable business build, 15.6″ screen in reasonable form-factor.

• Constraints: Dual-core CPU rather than quad-core (so heavy multi-thread workloads will lag modern machines). GPU (Quadro M500M) is older and modest by today’s standards (2 GB only) — if you do heavy 3D rendering or newer CAD, might struggle. Because it’s an older model, battery life, support, driver updates and future performance headroom are limited.
