The Lenovo ThinkPad L390 Yoga 2-in-1 is a 2018 convertible laptop built for office and small-business users who needed a ThinkPad's keyboard and durability with a touchscreen that folds flat into tablet mode. It shipped under model numbers including 20NT0006US, 20NT0008US, 20NT0009US, 20NT000AUS, and 20NT0005US, each tied to a specific processor and memory build. It holds resale value because the L-series chassis is tougher than most consumer ultrabooks from the same year, and 8th Gen Intel silicon still runs current business software without complaint. Pick your configuration and condition above for an instant cash offer, or see how the process works before you commit. If this isn't your exact laptop, you can still sell your laptop here — we buy most brands and years.

Confirm you have the ThinkPad L390 Yoga

The fastest way to confirm your exact build is Windows. Press the Windows key + R, type msinfo32, and press Enter — the System Model field will show one of the model numbers below. You can also run dxdiag to cross-check the processor and installed memory against what's listed on this page.

20NT0006US

  • 8th Gen Intel Core processor
  • Common i5 base configuration

20NT0008US / 20NT0009US

  • 8th Gen Intel Core processor
  • Memory and storage tier varies by SKU

20NT000AUS

  • 8th Gen Intel Core processor
  • Higher-tier configuration in most listings

20NT0005US

  • 8th Gen Intel Core processor
  • Entry-tier configuration in most listings

Prefer a visual check? Look for the ThinkPad logo on the lid with the red dot on the "i," a 360-degree hinge that lets the 13.3-inch display fold flat against the base, and a garageless stylus loop or pen clip on the side rather than a built-in silo. If you're not sure this is the right family at all, our model finder can help narrow it down.

Display & audio

13.3-inch FHD (1920 x 1080) IPS touchscreen with a 360-degree hinge for laptop, tent, stand, and tablet modes. Supports an active pen for note-taking, sold and stored separately since the chassis has no built-in garage.

Stereo speakers tuned for voice clarity over bass, paired with dual-array microphones for video calls.

Fingerprint reader is standard on most configurations, with an optional IR camera for Windows Hello face login on select SKUs. A TPM 2.0 chip is built in for enterprise encryption.

Ports & connectivity

The L390 Yoga keeps a full port set typical of business ThinkPads from this era, including a legacy Ethernet extension connector rather than a full-size RJ45 jack.

Battery, build & more

Internal, non-removable battery with Lenovo Rapid Charge support for a faster top-up when you're between meetings.

Chassis is built to MIL-STD-810G testing standards, common across the ThinkPad L-series, with a spill-resistant keyboard and a hinge rated for repeated full-rotation folding.

Ships in ThinkPad black. Configurations were sold with either Windows 10 Home or Windows 10 Pro depending on SKU.

The most common documented wear points are hinge looseness after years of tablet-mode folding and fine scratching on the glossy touch layer. Neither is universal, but check both before you grade the condition.

Frequently asked questions

01 How do I find the model number / exact configuration?
Run msinfo32 from the Windows Run dialog (Windows key + R) and check the System Model field, which will show one of the 20NT-prefixed numbers. If the laptop won't boot, check the underside sticker near the regulatory markings, though on some units it has worn off. Our Lenovo model number guide covers other places to look, including the BIOS setup screen if you can access it.
02 How do I tell it apart from the standard ThinkPad L390 (non-Yoga)?
The non-Yoga L390 has a clamshell hinge that opens to roughly 180 degrees and a non-touch display in most builds, while the Yoga folds a full 360 degrees into tablet mode and always ships with a touchscreen. If the screen doesn't respond to a finger tap or the hinge stops at a normal laptop angle, you have the standard L390, not the Yoga. The model number field from msinfo32 will also differ, since the two lines use separate model number ranges.
03 Can I sell it with damage (cracked screen, weak battery, won't turn on, account lock)?
Yes, most damage conditions are accepted and simply adjust the quote rather than block it. Cracked touchscreens, a battery that no longer holds charge, and units that won't power on all qualify for an offer through the configuration and condition picker above. The one hard requirement is that any Microsoft account or Windows login lock must be removed before shipping, since a locked laptop can't be tested or resold. If you're not sure how to remove a login lock, our data erasure guide covers the reset steps as well.
04 What raises the trade-in value the most?
The processor tier and overall cosmetic condition move the offer the most. An i7 configuration outvalues an i5 unit of the same age, and a hinge with no play plus a touchscreen free of deep scratches will grade higher than one with visible wear. Including the original power adapter also helps, since replacements for this barrel-free USB-C charger aren't always on hand at resale. A clean factory reset with no lingering user accounts speeds up testing and avoids any condition downgrade for a locked device.
05 How do I erase it and remove my accounts, and how do I get paid?
Go to Settings → System → Recovery → Reset this PC and choose to remove everything, then confirm the reset when Windows prompts you. Before that, sign out of your Microsoft account under Settings → Accounts, and if you enabled BitLocker, suspend or decrypt it so testing isn't blocked by an encryption lock. Once your quote is accepted, we send a prepaid, insured shipping label at no cost to you. Payment goes out after inspection, by PayPal, Venmo, Zelle, CashApp, or check, whichever you prefer. Full step-by-step details, including how to back up your files first, are in our data erasure protocols.
