The ASUS Vivobook S 14X OLED launched in 2022 and continued into 2023 as ASUS updated the internals, keeping the same 14-inch OLED-first design across both model years. It landed as a step up from the standard Vivobook line: a thin, metal-chassis laptop aimed at students, writers, and light creative work, built around a color-accurate display rather than raw graphics power. You will find it under model numbers like S5402ZA, S5402ZA-IS74, and the later K3405VA, K3405VC, and K3405VF, all covered on this page. It holds resale value well because the OLED panel and the optional dedicated graphics still outperform most laptops in this price tier years later. Pick your processor, graphics, and condition in the selector above for a live cash offer, or see how the process works before you commit. If you are ready to move on from it, this is also where you sell your ASUS laptop with us.

Confirm you have the Vivobook S 14X OLED

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. You can also flip the laptop over and read the sticker on the underside, which lists the full model string including any suffix. If Windows won't boot, the same sticker is your only source.

S5402 series

  • Includes S5402, S5402ZA, and S5402ZA-IS74
  • 2022 model year

K3405 series

  • Includes K3405, K3405VA, K3405VC, K3405VF, and K3405VF-ES74
  • 2023 refresh
  • Paired with 13th Gen Intel Core processors

Prefer a visual check? Look for the OLED panel sticker near the trackpad, a metal (not plastic) lid finish, and a fingerprint reader built into the power button on the keyboard deck.

Core hardware configurations

Processor

  • Intel Core i7, 12th Gen
  • Intel Core i7, 13th Gen
  • Intel Core i9, 13th Gen

Graphics

  • Integrated Intel graphics
  • NVIDIA RTX 2050 (12th Gen units)
  • NVIDIA RTX 3050 (13th Gen units)

Memory & storage

  • RAM is soldered to the board on this series, so the tier you buy is the tier you keep
  • Storage is a single M.2 PCIe SSD

The configuration that moves resale value the most is the graphics card. A unit with the RTX 3050 and a 13th Gen Core i9 sits well above an integrated-graphics i7 in demand, since it can still handle light gaming and GPU-accelerated editing.

Display & audio

Display

14-inch OLED panel at 2.8K resolution with a 90Hz refresh rate. This is the feature the model is built around, and it is a genuine step up from the LCD panels found on most laptops at this level.

Audio

Harman Kardon-certified stereo speakers, tuned for media and video calls rather than bass output.

Security

Fingerprint reader built into the power button, working with Windows Hello for sign-in.

Ports & connectivity

Port selection stayed largely consistent across the S5402 and K3405 revisions.

Left side
  • USB-C (data and charging)
  • HDMI
  • 3.5mm combo audio jack
Right side
  • USB-A 3.2
  • USB-A 2.0
  • microSD card reader

Battery, build & more

Build

Metal lid and deck with a thin, portable profile, closer in feel to a premium ultrabook than a typical mid-range laptop.

Software

Ships with Windows 11 and the MyASUS utility for driver updates, battery health settings, and system diagnostics.

Market positioning

Sits between entry-level ultrabooks and dedicated gaming laptops. The OLED display and optional RTX graphics keep it relevant for creative and light-gaming use well after purchase, which supports steady resale demand.

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 model listed under "System Model." The same tool, or dxdiag, will show your processor and installed graphics card. You can also check the sticker on the underside of the laptop, which lists the full model string. For RAM and storage, open Settings → System → About for memory, and Settings → System → Storage for drive capacity.
02 How do I tell it apart from the standard Vivobook S14 OLED?
The non-X Vivobook S14 OLED looks nearly identical but does not offer the RTX 2050 or RTX 3050 graphics options or the higher-end Core i9 configuration found here. If your model number ends in S5402 or K3405, you have the X variant covered on this page. If in doubt, check the model number in msinfo32 or on the underside sticker rather than judging by appearance alone.
03 Can I sell it with damage, a weak battery, or if it won't turn on?
Yes. Cracked screens, failing batteries, and units that won't power on can still be sold, and the condition picker above adjusts the offer accordingly. Before shipping, sign out of your Microsoft account under Settings → Accounts, and if BitLocker is enabled, suspend or remove the encryption key so the drive can be tested. A laptop still tied to your Microsoft account cannot be resold, so this step matters even on a dead or damaged unit.
04 What raises the trade-in value the most?
Configuration and condition matter most. A unit with the RTX 3050 and a 13th Gen Core i9 is worth more than an integrated-graphics i7, since the discrete GPU is what sets this model apart. Beyond that, an accurate cosmetic condition, a battery that still holds a reasonable charge, and having the original charger on hand all help. A functioning display with no dead pixels or burn-in matters more here than on a standard LCD laptop, given the OLED panel.
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" for a full wipe. Before that, go to Settings → Accounts and remove the device from your Microsoft account, and if BitLocker is turned on, suspend or decrypt it so the reset completes cleanly. Once the offer above matches your configuration and condition, print the free prepaid shipping label, pack the laptop, and send it in — shipping is free and insured. After our team tests the unit against what you declared, payment goes out by PayPal, Venmo, Zelle, CashApp, or check. Full details are in our data erasure protocols.
