The Dell G3 15 3579 (also written G3579, regulatory model P75F), released in 2018, was Dell's most affordable entry into PC gaming — an 8th-generation Coffee Lake machine in a slim 15.6-inch chassis that brought dedicated NVIDIA graphics to a sub-$1,000 price point. Because Dell offered it in a wide spread of configurations, from a modest i5 + GTX 1050 build up to an i7 + GTX 1060 Max-Q, your exact combination of parts decides the final resale price. If you've been thinking about where to sell your gaming laptop online, our trade-in service buys it outright for cash — no buyer negotiation, no listing fees. Before you choose your components above, confirm you have the G3 15 3579 specifically — not the pricier G5 15 5587 or G7 15 7588 from the same 2018 lineup, nor the later G3 15 3590 (2019) — since those are different machines on separate pages. Match the model, then select your specs above for an instant cash offer.

Confirm your exact Dell G3 15 3579

Several Dell G-series laptops from this era share the same blue-accent gaming look. The cleanest confirmation is the regulatory model on the bottom panel and the Service Tag readout:

Reg. Model: P75F G3 3579 / G3579 2018 · 8th-gen Intel

This is the G3 15 3579 if…

  • The bottom-panel label reads Regulatory Model P75F and the system identifies as G3 3579
  • The processor is an 8th-gen Intel (i5-8300H or i7-8750H) — not a 9th or 10th gen
  • The GPU is a GTX 1050, 1050 Ti, or 1060 Max-Q (no RTX, no GTX 1660 Ti)

It is NOT this page if…

  • The model reads 3590 → that is the 2019 Dell G3 15 (9th/10th-gen, RTX-capable)
  • It is a G5 5587 or G7 7588 → higher-tier 2018 siblings with stronger cooling and GPUs
  • It is a later G15 (5510/5511/5520, etc.) → newer chassis entirely

Frequently asked questions

01 How do I confirm my laptop is the G3 15 3579 and not a G5, G7, or the 2019 G3 3590?
Flip the laptop over and look for the regulatory label — the G3 15 3579 reads Regulatory Model P75F. In Windows, Settings → System → About (or the My Dell / SupportAssist app) will show the model as G3 3579 along with your Service Tag. The processor is an 8th-gen Intel (i5-8300H or i7-8750H); if you see a 9th- or 10th-gen chip or an RTX GPU, you most likely have the 2019 G3 3590 instead, which is a separate page. Our guide to finding your laptop's model number walks through reading the Service Tag.
02 Can I upgrade the RAM or storage in the G3 3579?
Yes — unlike thin ultrabooks, the G3 3579 is upgradable. It has two SODIMM slots and supports up to 32GB of DDR4-2666 (2× 16GB). For storage, it has an M.2 2280 NVMe SSD slot plus a separate 2.5" SATA bay, so you can run an SSD and a hard drive together. Upgrades you've added (more RAM, a larger or second drive) are reflected in your quote, so select the configuration as it currently is. Note: the optional Intel Optane module is a storage accelerator and does not count as system RAM.
03 Should I wipe my drive or pull it out before shipping?
Back up your game saves and personal files to an external drive or the cloud, then sign out of your Microsoft account and run a full Reset this PC → Remove everything from Windows before packing. You don't need to open the laptop or remove the SSD or hard drive yourself — our team performs certified data sanitation on every drive that reaches us. Review the full process on the data erasure protocols page.
04 Which configurations raise my G3 3579 trade-in value, and why use a trade-in service?
The GPU is the biggest single factor: a GTX 1060 Max-Q build is worth noticeably more than a GTX 1050 Ti or 1050. After that, an i7-8750H, 16GB or 32GB of RAM, and a roomy NVMe SSD all lift the offer, as does the optional backlit keyboard and the region-specific Thunderbolt 3 port. Condition matters too — a clean matte screen, working fans, and a battery that still holds a charge. Compared with listing on eBay, Swappa, or Facebook Marketplace, where you handle photos, buyer questions, payment risk, and shipping, our trade-in service gives you one upfront cash quote and a free, insured prepaid label. Plenty of people don't realize there's an easy cash option for older gaming laptops — we buy the full Dell G-series range.
05 How fast do I get paid, and what payment methods are available?
Once your Dell G3 arrives at our facility and our team completes functional and cosmetic inspection, payment is approved within two business days. Most sellers have money in hand within roughly 5–7 business days of drop-off. You choose how to get paid: PayPal, Venmo, Zelle, or CashApp for fast digital transfers, or a physical check by mail. Your prepaid UPS shipping label is free and the shipment is insured.
