The Dell Latitude 15 3510 is a 15.6-inch business laptop built around 10th generation "Comet Lake" Intel processors, aimed at IT departments outfitting fleets of everyday office machines rather than power users chasing benchmarks. It shipped with a spill-resistant keyboard, TPM 2.0, and the plain, repairable chassis Dell used across the entry-level Latitude 3000 line. That combination of low-drama hardware and wide corporate deployment is exactly why used units stay in steady demand on the resale market: they are cheap to refurbish, easy to image for a new user, and parts-compatible across a large installed base. If this is the laptop sitting in your drawer, pick your Intel Core i7 10th Gen configuration and condition above for an instant cash offer, or see how the process works before you commit. You can also browse sell your Dell laptop for other Latitude and XPS models we buy.

Confirm you have the Latitude 15 3510

The fastest way to confirm the exact model on a Dell laptop is through Windows itself. Press Windows key + R, type msinfo32, and press Enter. The System Summary window lists the exact model name, BIOS version, and installed processor. Alternatively, Settings → System → About shows the device name. The Dell Service Tag, printed on a label on the underside of the chassis, is the most reliable identifier if you ever need to check the original configuration through Dell's support site.

Latitude 3510

  • Service Tag sticker on the base panel, near the regulatory markings
  • System model listed as "Latitude 3510" in msinfo32 or Dell SupportAssist
  • BIOS setup (F2 at boot) shows the same model string and installed CPU

Prefer a visual check? The 3510 has a plain black plastic lid and deck with a single Dell logo, no aluminum or magnesium panels, a rounded hinge design, and a keyboard with a numeric keypad on the right side.

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 name, processor, and BIOS version in System Summary. The Dell Service Tag on the base panel confirms the original build if you look it up on Dell's support site. This tells you the processor tier, whether you have integrated or discrete graphics, and the installed RAM and storage, all of which affect your quote.
02 How do I tell it apart from the Latitude 5510?
Check the chassis material and the model string in Windows System Information. The Latitude 3510 uses an all-plastic black chassis, while the 5510 steps up to a more rigid build and was offered with faster memory and additional port options. Both share a similar 15.6-inch footprint and 10th generation processors, so the surest confirmation is the model name shown in msinfo32 or on the Service Tag label, not the outward appearance alone.
03 Can I sell it with damage, a weak battery, or if it won't turn on?
Yes. We buy Latitude 3510 units with cracked screens, degraded batteries, and units that fail to boot, and the condition picker above adjusts your quote accordingly. Before shipping, sign out of any Microsoft account tied to the device and remove it from Windows to avoid it being locked to your login once it reaches us. If BitLocker is enabled, suspend or remove it so the drive can be tested and wiped.
04 What raises the trade-in value the most?
Physical condition and completeness matter most on a laptop this common. A screen free of cracks or dead pixels, a keyboard with all keys intact, a battery that still holds a reasonable charge, and the original Dell power adapter included all push the offer up. Configuration matters too: units with the discrete MX230 graphics, more RAM, or a Full HD display typically quote higher than base HD, integrated-graphics builds.
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. Before you do, sign in to your Microsoft account online and remove this device from your account list, and suspend BitLocker if it is enabled so the reset completes cleanly. Once the reset finishes, the laptop is ready to ship. Shipping is free and insured, and once we test the unit against your listed configuration and condition, payment goes out by PayPal, Venmo, Zelle, CashApp, or check.
