The Lenovo ThinkPad E15 is a line of 15.6-inch business laptops that Lenovo sold across four generations between 2020 and 2022, built for students, small offices, and professionals who wanted ThinkPad build quality and a full-size keyboard without flagship pricing. Gen 2 units carry model numbers like 20T8, 20T9, 20TD, and 20TE. Gen 4 units carry codes such as 21ED, 21EE, 21E6, and 21E7. Lenovo sold Intel and AMD boards side by side within the same generation, so the processor inside your unit matters more than the year on the box. These are still solid daily drivers for spreadsheets, browsers, and remote work, and the ThinkPad chassis holds up well used, which keeps demand for them steady. Pick the processor, memory, storage, and condition that match your laptop in the picker above for an instant cash offer, see how the process works, or go straight to sell your laptop when you are ready.

Confirm you have the Lenovo ThinkPad E15

The fastest way to check is inside Windows. Press Windows key + R, type msinfo32, and press Enter. The "System Model" field shows the exact machine type, for example 20T8 or 21ED. Typing dxdiag and checking the System tab works the same way. You can also flip the laptop over and read the model number printed on the bottom label, though on older units that text can be worn or smudged.

Prefer a visual check? Later generations have a slightly slimmer, more rounded lid than the boxier early units, and the ThinkPad logo dot on the lid glows red on newer boards. If your unit has a fingerprint reader built into the power button on the top-right of the keyboard deck, it is a later configuration rather than an entry-level early one. When in doubt, the system info check above is the reliable method — see our Lenovo model number guide for more.

Core hardware configurations

Processor

  • AMD Ryzen 7 4000 Series
  • AMD Ryzen 5 5000 Series
  • AMD Ryzen 7 5000 Series
  • Intel Core i5 10th / 11th / 12th Gen

  • Integrated Intel Iris Xe on later 11th and 12th Gen Core chips
  • Integrated AMD Radeon Graphics on all Ryzen configurations

Memory & storage

  • Storage is a swappable M.2 NVMe SSD on every generation of this line
  • RAM capacity depends on the configuration you select above
  • Higher RAM and larger SSD tiers are the biggest lever on resale value here, more than the chip generation alone

Display & audio

Display

Most configurations use a 15.6-inch Full HD (1920x1080) IPS anti-glare panel. Entry-level builds in some generations shipped with a lower-resolution HD panel instead, so check yours before assuming FHD.

Audio

Dual stereo speakers with Dolby Audio processing, plus a dual-array microphone for calls and conferencing.

Security

Many configurations add a fingerprint reader built into the power button, and some include an IR camera for Windows Hello face login.

Ports & connectivity

Port selection stayed close to the classic ThinkPad layout across all four generations, with the main change being the addition of Thunderbolt support on later Intel builds.

Left side
  • Rectangular ThinkPad power connector
  • RJ-45 Ethernet
  • HDMI
  • USB-C (USB4 / Thunderbolt 4 on select Intel configurations)
Right side
  • USB-A 3.2
  • USB-A 2.0
  • Headphone/microphone combo jack
  • Kensington lock slot

Battery, build & more

Battery

Battery life is adequate for a light workday of browsing and document editing, with capacity varying slightly by generation. Most configurations support Lenovo's RapidCharge fast-charging. Battery health is one of the first things we test when your unit arrives.

Build & finish

Black soft-touch chassis with the standard ThinkPad keyboard deck. Later generations trimmed weight and bezel size slightly compared to the earliest units.

Software

Ships with Windows 10 or Windows 11 depending on the year of purchase, plus Lenovo Vantage for driver updates and battery/keyboard settings.

Market positioning

This series sits in the budget-to-midrange tier of the ThinkPad lineup. Later generations with 11th or 12th Gen Intel chips or Ryzen 5000 chips hold value better than the earliest 10th Gen and Ryzen 4000 builds.

Frequently asked questions

01 How do I find the model number or exact configuration?
Press Windows key + R, type msinfo32, and press Enter. The System Model field shows the exact machine type, such as 20T8 or 21ED. You can also check the sticker on the bottom of the laptop, though it can wear off on older units. For processor, RAM, and storage, the same msinfo32 window lists all three under the System Summary. If you want a walk-through with pictures, our Lenovo model number guide covers it step by step.
02 How do I tell it apart from the ThinkPad E14?
The E14 is the 14-inch sibling in the same family, and the two look nearly identical apart from size. Measure the screen diagonally, or check the model number: E15 units use the codes listed above, while E14 units carry a different four-character prefix entirely. If you have removed the laptop from its original box, the system info check with msinfo32 is the most reliable way to confirm which one you have.
03 Can I sell it with damage, a weak battery, or an account lock?
Yes. A cracked screen, a battery that drains fast, or a unit that will not power on can still be sold, and the quote adjusts to reflect the condition rather than being refused outright. What you cannot ship is a laptop still signed into a Microsoft account with a BIOS supervisor password enabled, since that leaves the device locked for the next owner. Sign out of your Microsoft account and clear any BIOS password before shipping. If the laptop truly will not turn on, note that clearly when you submit your condition, since we still test it on arrival.
04 What raises the trade-in value the most?
The processor and RAM tier matter most, since a Ryzen 7 or Core i7 build with more memory outlasts a base Ryzen 5 or Core i5 configuration in daily use. After that, cosmetic condition of the lid and keyboard deck, a battery that still holds a real charge, and having the original power adapter on hand all push the offer higher. A working fingerprint reader and an unblemished screen also help, since both are common points of wear on this line.
05 How do I erase it, remove my accounts, and get paid?
Go to Settings → System → Recovery, then choose Reset this PC and select "Remove everything" with a full drive clean. Before that, go to Settings → Accounts and remove the device from your Microsoft account, and if BitLocker is enabled, suspend or decrypt it first so the reset does not stall. Once the reset finishes and the device restarts to setup, you are ready to ship. Shipping is free and insured, and payment goes out after testing by PayPal, Venmo, Zelle, CashApp, or check.
