Seller's guide

The DIY guide to selling your device

Maybe it's a little too old for us to buy. Maybe you didn't love our price. Maybe you're just checking what it's worth. No hard feelings, here's how to sell it yourself and get it right the first time.

Selling a device yourself isn't complicated, but a few small things separate a smooth sale from a returned package and a bad review. Most of them come down to one idea: describe exactly what you have, and prove it.

This isn't a tutorial on clicking around eBay. It's the short list of device-specific things that actually decide whether your sale goes well, getting the model and specs right, knowing the real battery health, catching hidden locks before a buyer does, and packing so it survives the trip. Get these right and the rest takes care of itself.

Step 1 · Pick a platform

Where to actually sell it

eBay is the default because it has the most buyers and a structured listing flow. It isn't your only option, and the right one depends on how fast you want to be done. Whichever you pick, the prep below is identical.

eBay

Best reach

The widest pool of buyers, so the most likely to sell. You cover the fees and the shipping, and any dispute is between you and the buyer.

Swappa

Lower fees

Built for tech, with required photos and condition checks. Smaller audience, but buyers know what they want.

Facebook Marketplace

Local, cash

No shipping and no fees if you meet in person. Less protection, so meet in public and test before money changes hands.

Mercari

Simple

Easy listing and prepaid labels. Decent for mainstream models, thinner for high-end or gaming machines.

Get the Exact Model, Not Just the Brand

"Dell laptop" is not a listing. Buyers search for a specific model, and pricing swings hard between near-identical-looking machines. Find the precise name before anything else. Our find your model guide covers every method in detail.

Watch the suffix. Trailing letters on a model name can mean a different screen, GPU, or CPU tier, and buyers notice. Match what's printed on your machine, don't round it to the nearest familiar name.

Read Your Real Specs Off the Machine

Don't trust the specs from the original product page. RAM gets upgraded, drives get swapped, and the machine in your hands may not match the factory sheet. Read what's actually installed.

  • Windows: Settings › System › About gives the processor, installed RAM, and system type. Device Manager › Display adapters lists every GPU. Storage lives under Settings › System › Storage.
  • Mac: About This Mac shows the chip, memory, and storage at a glance. Click More Info or open System Information for the exact CPU, graphics, and drive.

Write down the four numbers buyers care about most: CPU model, RAM amount, storage size and type (SSD or HDD), and the GPU. Those four, plus condition, drive the price.

Know the Battery's Real Health, Not Its Age

Battery condition is one of the first questions a buyer asks, and "it was fine for me" is not an answer. You can pull the actual numbers in two minutes.

  • Windows: open Command Prompt and run powercfg /batteryreport. It saves an HTML file. Open it and compare Design Capacity to Full Charge Capacity: 40,000 mWh against a 50,000 mWh design is about 80 percent health. That ratio is the honest number for your listing.
  • Mac: System Settings › Battery › Battery Health, or hold Option and click the battery menu. Cycle count is under System Information › Power.
If it's worn, say so. A buyer who knows a battery is at 70 percent is happy. A buyer surprised by it opens a return.

Find and Clear Every Lock Before You Ship

This is the step that quietly ruins more sales than sellers expect. A locked device is useless to a buyer, and most locks are invisible until someone tries to set it up fresh. Check all of these before you list.

  • BIOS or supervisor password. Restart and tap the setup key (often F2, F10, or Delete). If it demands a password you don't have, clear it while you still can.
  • Work or school enrollment. A device signed into a company or school account may be managed (MDM) or domain-joined, and a factory reset won't always remove it. Unenroll it through the organization first.
  • Activation Lock (Apple). Turn off Find My and sign out of your Apple ID before wiping. A device still tied to iCloud is a brick to the buyer.
  • Drive encryption keys. If BitLocker or FileVault is on, decrypt or do a clean reinstall so the buyer isn't locked out by a recovery key only you have.
  • Your accounts and data. Record your specs first, then do a full factory reset so it boots to a clean setup. Our erase guide covers every method.
If a lock can't be cleared, disclose it plainly. Listing a locked machine as "for parts or not working" is fair and legal. Listing it as working is the fastest way to a forced refund.

Write a Listing That Doesn't Come Back

You already did the hard part. Now turn those notes into a listing that sets the right expectation: a buyer should know exactly what's arriving, so nothing about the package surprises them.

  • Title: write it as a keyword string, not a sentence. Lead with brand, model, and the specs buyers filter by, CPU, RAM, storage, screen, condition. eBay caps titles at 80 characters. "Dell XPS 13 9310 i7-1165G7 16GB 512GB SSD 13.4 FHD+ Win 11" reads like a real search; "Fast Dell laptop, great condition" does not.
  • Photos: use real photos of the actual device, not stock images. Show the screen powered on, the ports, and any scratch, dent, or dead pixel up close. A flaw you photograph is a flaw the buyer accepted. A flaw you hide is a refund.
  • Include: the battery health number from earlier, and exactly what's in the box, charger, accessories, anything else.

Pack It So It Survives the Trip

A device that arrives cracked is your problem, not the carrier's, in the eyes of most buyers. Packing well is cheap insurance. Use the original box if you kept it, or a sturdy box with room for padding on every side. Wrap it fully so nothing gets into the ports or vents, and fill the gaps so nothing shifts.

Insure it, and get tracking. Insure for the sale price. eBay requires signature confirmation on orders of $750 or more; below that it usually isn't worth it. A package that goes missing without tracking is a loss you usually eat.

Deal With Buyers Without Losing the Sale

Most buyer messages are simple questions, and answering them quickly and politely is what earns good feedback. A calm, factual tone defuses almost everything.

  • Answer with facts. If someone asks about the battery or a spec, you already have the answer written down. Send the number or a photo. Specifics build trust faster than reassurance.
  • Handle lowballs gracefully. A lowball is an opening move, not an insult. Counter politely or decline in one friendly line. No need to argue.
  • Accept fair returns. If a buyer has a fair complaint about something you missed, taking the return is almost always cheaper than a drawn-out dispute, and it protects your account.
  • Keep your records. Save your photos, the battery report, and the tracking number until the sale is closed. If a dispute happens, evidence ends it quickly.
The bottom line. Every step here serves one habit: say exactly what the device is, and show it. An honest listing rarely comes back, and that's the same way we work, since every device we buy is set up and tested by hand before we make a final offer.
