The Dell Inspiron 15 3520 arrived in 2022 as Dell's mainstream 15.6-inch laptop, built for students, home offices, and everyday browsing and document work rather than gaming or creative rendering. Dell tracks this chassis under the regulatory model number P112F, which you will find printed on the bottom sticker next to the service tag. It shipped with 12th Gen Intel Core i5 and i7 processors, a full-size keyboard with number pad, and a straightforward port selection that made it a common pick for budget-conscious buyers who wanted a reliable Windows machine without paying for extras they would not use. That practicality is exactly why it still holds resale value: parts are common, the platform is well documented, and demand for an affordable secondary laptop has not gone away. Pick your processor configuration and condition above for an instant cash offer, or see how the trade-in process works before you commit. Ready now? Sell your Dell laptop in a few minutes.

Confirm you have the Dell Inspiron 15 3520

The fastest way to confirm your exact model is through Windows itself. Go to Settings → System → About and check the "Device specifications" section, which lists the model name and installed processor. You can also flip the laptop over and read the bottom sticker, which shows both the marketing name and the service tag Dell uses for support lookups. If Dell SupportAssist is installed, opening it will display the same information without any digging.

Inspiron 15 3520

  • Shown under Settings → System → About as the device name
  • Confirmed by the Dell SupportAssist app, if installed
  • Printed on the bottom chassis sticker along with the service tag

P112F

  • Dell's internal regulatory model number for this chassis
  • Found on the bottom rating label, usually below the service tag
  • Shared across both the i5 and i7 configurations, so it will not tell you which processor you have

Prefer a visual check? Look for a solid black plastic lid and deck with no dual-tone accents, a centered silver Dell logo on the lid, and a full keyboard layout that includes a number pad on the right side. There is no fingerprint reader on this model, and the charging port is a round barrel connector rather than USB-C.

Core hardware configurations

Processor

  • Intel Core i5, 12th Gen
  • Intel Core i7, 12th Gen

Graphics

  • Intel Iris Xe Graphics, integrated with the processor
  • Shares system memory rather than using dedicated video RAM
  • No discrete GPU option on this model

Memory

  • DDR4 RAM installed on a SO-DIMM module
  • User-accessible for a later upgrade
  • More RAM helps Iris Xe performance more than it does on discrete-GPU machines

Storage

  • M.2 PCIe NVMe SSD
  • Single M.2 slot, upgradable
  • Larger storage tiers and the i7 processor move resale value the most

Display & audio

Display

A 15.6-inch Full HD (1920x1080) anti-glare panel with a standard refresh rate. It is built for text, browsers, and video playback rather than color-critical or high-frame-rate work.

Audio

Stereo speakers sit along the underside of the chassis, tuned for clear speech and video calls rather than deep bass. A headphone and microphone combo jack covers wired audio.

Webcam

A 720p webcam is mounted above the display, suited for video calls and basic recording rather than sharp video capture.

Ports & connectivity

Port selection favors everyday practicality: enough USB-A for peripherals, an SD card reader for photo transfers, and a wired Ethernet jack for a stable connection when Wi-Fi is not an option.

Wired
  • 2x USB-A 3.2 Gen 1
  • 1x USB-A 2.0
  • HDMI
  • RJ45 Ethernet
  • SD card reader
  • Headphone/microphone combo jack
  • Barrel-connector DC-in for charging
Wireless
  • Wi-Fi 6
  • Bluetooth

Battery, build & more

Battery

A 3-cell battery covers light, everyday use. It is not built for long unplugged sessions of heavier work, so keep the charger nearby if you are running demanding tasks.

Finishes

The chassis is a solid black plastic build, keyboard deck included, with no metal panels and a single finish across all configurations.

Software

Ships with Windows, upgradable through standard Windows Update channels. No custom Dell software beyond SupportAssist and driver utilities is required to run it.

Market positioning

This model sits in the budget-to-mainstream tier. It remains a steady seller as a secondary or student laptop, since parts availability and buyer demand for an affordable Windows machine stay consistent.

Known issues

Single-channel memory on lower-RAM configurations can bottleneck Iris Xe graphics performance, since the integrated GPU relies on system memory bandwidth. This is a known trait of Iris Xe machines generally, not a defect specific to one unit.

Frequently asked questions

01 How do I find the model number or exact configuration?
Go to Settings → System → About on Windows, which lists the device name and installed processor under "Device specifications." The bottom sticker on the chassis also shows the service tag and regulatory model number P112F, which Dell support can use to pull the full build sheet, including RAM and storage size. If you want a broader walkthrough for Dell laptops in general, our Dell model number guide covers a few other lookup methods too.
02 How do I tell it apart from the Dell Inspiron 15 3525?
The Inspiron 15 3525 uses the same chassis but runs an AMD Ryzen processor instead of Intel, and it does not have Iris Xe graphics. Checking Settings → System → About will show "AMD" instead of "Intel" in the processor field if you actually have the 3525. Externally the two look almost identical, so the on-screen check is more reliable than a glance at the case.
03 Can I sell it with damage, like a cracked screen, weak battery, or a laptop that won't turn on?
Yes, damaged and non-working units are accepted, and the condition picker above already accounts for this. A cracked screen, a battery that no longer holds a charge, or a laptop that will not power on all still have resale value in parts and refurbishment. The one requirement that applies regardless of condition is that any Microsoft account lock must be removed and BitLocker suspended before shipping, since a locked device cannot be tested or resold.
04 What raises the trade-in value the most?
The processor configuration matters most, with the i7 config typically valued above the i5. After that, a larger storage tier and more RAM help, along with a chassis free of cracks or heavy wear. Including the original charger and confirming the laptop powers on and boots normally both support a stronger offer, since it lets us skip a testing step that would otherwise slow things down.
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 the option that removes everything. Before you start, sign out of and remove the device from your Microsoft account under Settings → Accounts, and suspend BitLocker if it is enabled so the reset does not stall. Once the reset finishes and the laptop is ready to ship, we cover shipping with insurance, and payment goes out after testing by PayPal, Venmo, Zelle, CashApp, or check.
