Marketed largely as portable workstations,[3] many P series laptops can be configured with high-end mobile workstation-class Intel processors[4] as well as error correction code (ECC) memory (only with Xeon and select Core HX processors) and a discrete Nvidia Quadro GPU.

It comes with a variety of "high-end" options such as Intel Xeon E3-1500M v5 processors, 4K IPS screens and DDR4 ECC RAM up to 64 GB.

The P series introduced a cooling system known as FLEX (Full Load Experience) that features two fans connected by a heat pipe and located near the CPU and GPU.

Its ports had been re-arranged, it was slightly thinner than its predecessor, and it reintroduced indicator lights for hard drive activity.

It supports up to three internal storage devices and has a single USB Type-C Thunderbolt 3 port while also featuring Mini DisplayPort and HDMI connections.

It has up to a Xeon E3-1500M series CPU, an Nvidia Quadro GPU, weighs 3.4 kilograms and is 3.1 centimeters thick.

It removed the mechanical docking port and ExpressCard slot, and features a narrower keyboard which is present on other ThinkPads.

[21] Based on the ThinkPad T580, the P52s features a camera shutter, lateral instead of bottom-mounted docking port, and 8th Gen Core i5/i7 low power CPUs.

It features Intel 8th Gen Coffee Lake U-series processors and Nvidia Quadro Pascal-based graphics.

A redesign of the P52, the P53 features a 4K UHD OLED Touch display, Wi-Fi 6, Intel 9th Gen Coffee Lake Refresh Core i5/i7/i9 and Xeon E-2200M mobile processors and Nvidia Quadro RTX Turing-based GPUs.

The P53s is an update to the P52s, which features Intel 8th Gen Coffee Lake U-series Processors, Nvidia Quadro P520 Graphics and up to 4K UHD (3840 x 2160) display, available with Dolby Vision high dynamic range (HDR) technology.

The P73 features new Intel 9th Gen Coffee Lake Refresh CPUs and Nvidia Quadro RTX Turing GPUs.
