ThinkPad P50s i7-6th, 16GB RAM, 256GB SSD (Pre-Owned)

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.
