Lenovo ThinkBook 16 Gen 6 is a 2023 mid-size business laptop built for people who want ThinkPad-adjacent reliability without the ThinkPad price tag. It shipped in two chassis families: the Intel-based ThinkBook 16 G6 IRL and the AMD-based ThinkBook 16 G6 ABP, both sold under a spread of model numbers including 21KH and 21KK variants. It holds resale value because the 16-inch, 16:10 display and full-size keyboard suit long work sessions, and because both platforms were still current enough in 2023 to run modern business software without strain. If you have one sitting in a drawer, pick your processor, memory, storage and condition in the picker above for an instant cash offer, or see how the process works before you commit. If this isn't the laptop you're holding, you can still sell your laptop through the same flow.

Confirm you have the ThinkBook 16 Gen 6

The fastest way to check is Windows itself. Press Windows key + R, type msinfo32, and press Enter. The System Model field will show the exact model number. Alternatively, flip the laptop over and read the sticker near the regulatory markings, which lists the model number and MTM (Machine Type Model) code directly.

ThinkBook 16 G6 IRL (Intel)

  • Model numbers include 21KH, 21KH000AUS, 21KH00VNUS, 21KH000BUS, 21KHX003US
  • Paired with Intel Core i5 or i7 13th Gen processors
  • "IRL" appears in the MTM string on the bottom sticker

ThinkBook 16 G6 ABP (AMD)

  • Model numbers include 21KK000, 21KK000UUS, 21KK000NUS, 21KKA02QUS
  • Paired with AMD Ryzen 5 or Ryzen 7 7000 Series processors
  • "ABP" appears in the MTM string on the bottom sticker

Prefer a visual check? Both variants share the same 16-inch chassis and dual-tone grey finish, so the badge is your best clue. AMD units carry a Ryzen sticker near the palm rest or keyboard deck, while Intel units carry an Intel Core sticker in the same spot. If neither sticker is present, the bottom-panel model number is the only reliable tell. For a broader walkthrough, see how to find your Lenovo model number.

Display & audio

Display

16-inch panel in a 16:10 aspect ratio, available in non-touch or touchscreen versions depending on how the unit was configured at purchase. The taller aspect ratio gives more vertical space for documents and spreadsheets than a standard 16:9 screen.

Audio

Built-in stereo speakers with Dolby Audio tuning, aimed at video calls and media playback rather than critical listening. A combo headphone/microphone jack is present for wired headsets.

Security

A fingerprint reader is integrated into the power button on most configurations, and the chassis supports TPM 2.0 for Windows Hello and BitLocker. Check your specific unit before assuming a webcam-based IR login is present.

Ports & connectivity

The ThinkBook 16 Gen 6 keeps a business-friendly port mix rather than trimming down to USB-C only, which is one reason it still appeals to buyers who rely on wired peripherals.

Wired
  • USB-A ports
  • USB-C, with Thunderbolt 4 support on Intel configurations
  • HDMI output
  • Combo headphone/microphone jack
Wireless
  • Wi-Fi 6E
  • Bluetooth

Battery, build & more

Battery

A multi-cell battery is standard across configurations, with Rapid Charge support on select units. Actual runtime depends heavily on processor choice and display type, so weak battery life alone is not disqualifying for a trade-in.

Finishes

The chassis ships in Lenovo's standard ThinkBook grey with a textured lid, designed to resist visible fingerprints and light scuffing better than a glossy finish.

Software

Sold new with Windows 11, either Home or Pro depending on configuration. A clean Windows installation and a signed-out Microsoft account make the resale process faster on your end.

Market positioning

This sits in Lenovo's mid-range business line, a step below the ThinkPad series in build materials but ahead of consumer IdeaPad models in port selection and keyboard quality. That middle position keeps demand steady in the used market.

Frequently asked questions

01 How do I find the model number and exact configuration?
Press Windows key + R, type msinfo32, and press Enter to see the exact system model, processor, and installed RAM in one window. The bottom-panel sticker lists the same model number if the laptop won't power on. For installed storage capacity, open File Explorer and check the properties of your main drive, or use msinfo32's Components section for the exact SSD model.
02 How do I tell it apart from the ThinkBook 16 Gen 5?
Check the model number on the bottom sticker or in msinfo32. Gen 6 units carry 21KH or 21KK model numbers, while Gen 5 units use a different numbering series and shipped with 12th Gen Intel or Ryzen 6000 Series processors instead of 13th Gen Intel or Ryzen 7000 Series. The two generations look nearly identical from the outside, so the badge and sticker are more reliable than appearance alone.
03 Can I sell it with damage, a weak battery, or if it won't turn on?
Yes. A cracked screen, a battery that no longer holds a charge, or a unit that won't power on can still be sold, and the condition picker above accounts for that. Before shipping, sign out of your Microsoft account and remove the device from it under Settings → Accounts, since a laptop still tied to an active account can't be resold or refurbished. If the drive is encrypted with BitLocker, note that as well so testing isn't delayed.
04 What raises the trade-in value the most?
Higher installed RAM and larger SSD storage make the biggest difference, followed by overall cosmetic condition and whether the original charger is included. An Intel Core i7 or Ryzen 7 configuration also quotes higher than the i5 or Ryzen 5 variants at the same condition grade. A clean, factory-reset Windows installation with no pending account locks helps the quote go through without delays.
05 How do I erase it and get paid?
Go to Settings → System → Recovery, then choose Reset this PC and select "Remove everything" with a full clean of the drive. Before resetting, remove the laptop from your Microsoft account under Settings → Accounts → Your info, and suspend BitLocker under Settings → Privacy & security → Device encryption if it's enabled. Once your offer is accepted, we send a free, insured shipping label. Payment goes out after inspection, by PayPal, Venmo, Zelle, CashApp, or check. Full details are in our data erasure protocols.
