The Lenovo ThinkPad P73 is a 2019 mobile workstation built for engineers, designers, and anyone who needed a 17.3-inch screen and real GPU horsepower in a ThinkPad chassis. It shipped as machine type 20QR and 20QS, with common SKUs including 20QRS00400 and 20QR000NUS. Lenovo built it around 9th-gen Intel silicon and NVIDIA Quadro graphics, aimed at CAD, 3D rendering, and other ISV-certified workloads rather than everyday browsing. Machines like this hold value because the parts inside them (Xeon processors, professional Quadro GPUs, ECC memory) are still relevant to the CAD and simulation crowd, and because ThinkPad build quality tends to survive years of daily use.

You can also compare it against other Lenovo laptops we buy.

Confirm you have the ThinkPad P73

The fastest way to check is Windows itself. Press the Windows key + R, type dxdiag, and press Enter to see the system model under the System tab, or type msinfo32 for a fuller readout including BIOS version. The machine type and model number are also printed on the bottom panel sticker, right next to the serial number.

20QR

  • Base machine type for most P73 configurations
  • Covers a range of CPU and Quadro GPU pairings
  • Sold through both retail and enterprise channels

20QRS00400

  • Specific model number under the 20QR machine type
  • Denotes a fixed factory configuration, not a build-to-order unit
  • Confirm exact CPU/GPU pairing via dxdiag before quoting

20QS / 20QR000NUS

  • 20QS is a parallel machine type used for select P73 builds
  • 20QR000NUS denotes a US-market retail configuration
  • Both use the same chassis and port layout as 20QR

Prefer a visual check? Look for the ThinkPad logo with the red dot on the lid, a black soft-touch 17.3-inch chassis, and a red TrackPoint nub centered in the keyboard. The P73 is noticeably thicker and heavier than a standard ThinkPad T-series laptop, which reflects the larger GPU and cooling system inside.

Core hardware configurations

Processor

  • Intel Core i7, 9th generation
  • Intel Core i9, 9th generation
  • Intel Xeon (workstation-class, supports ECC memory)

Graphics

  • Integrated Intel graphics
  • NVIDIA Quadro P620
  • NVIDIA Quadro T2000
  • NVIDIA Quadro RTX 3000, RTX 4000, or RTX 5000

Memory

  • DDR4 SODIMM, expandable across multiple slots
  • ECC memory support when paired with a Xeon processor
  • Memory configuration moves resale value less than GPU tier does

Storage

  • M.2 NVMe SSD storage, with capacity varying by build
  • Some configurations add a secondary drive bay
  • An upgraded RTX-tier GPU affects your offer far more than storage size

Display & audio

Display

17.3-inch panel options ranged from FHD IPS to a 4K UHD IPS panel with wide color coverage, aimed at color-critical CAD and design work. Confirm which panel you have, since it is not always visible from the outside.

Audio

Dual stereo speakers tuned with Dolby Audio processing, plus a combo headphone/microphone jack. Fine for reviewing renders and calls, not a substitute for external monitors.

Security

Fingerprint reader and an IR camera for Windows Hello facial login, along with a discrete TPM chip. Some builds add an optional smart card reader for enterprise environments.

Ports & connectivity

The P73's thick chassis leaves room for a full workstation port set, something thinner laptops from the same era had already given up.

Left side
  • Thunderbolt 3 (USB-C)
  • USB 3.1 Type-A
  • HDMI
  • Mini DisplayPort
Right side
  • Additional USB 3.1 Type-A ports
  • SD card reader
  • Gigabit Ethernet
  • Headphone/microphone combo jack

Battery, build & more

Battery

Internal battery with support for a rear slice battery on select configurations, letting the unit run longer under sustained GPU workloads. Battery health is worth checking before you quote, since these packs age with heavy rendering use.

Build

Black soft-touch ThinkPad chassis with a spill-resistant keyboard and MIL-SPEC durability testing. It is noticeably heavier and thicker than consumer 17-inch laptops, a direct trade-off for workstation cooling.

Software & certification

Shipped with Windows 10 Pro and carries ISV certification for professional software such as AutoCAD and SolidWorks, a detail that matters to workstation buyers evaluating a used unit.

Known issues

Sustained GPU-heavy workloads can push fan noise and thermals higher than on consumer laptops, which is expected for this class of machine rather than a defect. Hinge wear is also worth checking on units with heavy daily use, given the size and weight of the lid.

Frequently asked questions

01 How do I find the model number or exact configuration?
Run dxdiag or msinfo32 from the Windows Run box for a quick software readout, or flip the laptop over and read the sticker on the bottom panel. The sticker lists the machine type (20QR or 20QS) and the full model number, such as 20QRS00400. If you want to confirm CPU, GPU, RAM, and storage together, Windows Device Manager and Task Manager's Performance tab will show all four without opening the case. This is the fastest way to make sure the configuration you select above matches what you actually have.
02 How do I tell it apart from the ThinkPad P53?
The ThinkPad P53 is the closest look-alike, since it shares the same chassis design and generation of Quadro graphics options. The clearest way to separate them is the machine type sticker on the bottom, which reads 20QR or 20QS for the P73 and a different prefix for the P53. Processor generation also differs slightly between the two lines, so checking dxdiag alongside the sticker gives you a reliable answer even if the label has worn off.
03 Can I sell it with damage, a cracked screen, or a weak battery?
Yes, in most cases. Select the condition that matches your unit above and the quote adjusts automatically to reflect a cracked screen, a failing battery, or a unit that won't power on. What we cannot accept is a laptop still locked to your Microsoft account. Before shipping, go to Settings → Accounts and remove your Microsoft account from the device, and make sure BitLocker is either disabled or suspended so the drive is accessible for testing. A locked or encrypted-without-access unit will delay your payout.
04 What raises the trade-in value the most?
The GPU tier matters more than almost anything else on this model. A unit configured with a Quadro RTX 4000 or RTX 5000 will draw a stronger offer than the same laptop with integrated graphics or a Quadro P620, since those cards are what workstation buyers are actually paying for. Cosmetic condition, a working battery, and an original charger all help too, but graphics tier and overall functional condition drive most of the difference.
05 How do I erase it and get paid?
Back up anything you want to keep, then go to Settings → System → Recovery → Reset this PC and choose to remove everything. Before that finishes, sign out of and remove the device from your Microsoft account under Settings → Accounts, and check Settings → Privacy & Security → Device Encryption to suspend or disable BitLocker so the drive isn't locked during testing. Once that's done, print the prepaid shipping label from your confirmation email, pack the laptop with any accessories you're including, and send it in. Shipping is free and insured. After our team tests the unit against the condition you selected, payment goes out by PayPal, Venmo, Zelle, CashApp, or check. Full details are in our data erasure protocols.
