Looking to sell your Alienware m15 R4 gaming laptop for cash? Launched in early 2021 as one of the first laptops to ship with NVIDIA's RTX 30-series “Ampere” graphics, the m15 R4 pairs a 15.6-inch display with 10th-gen Intel Core processors inside Alienware's signature “Legend” chassis. It carries the regulatory model code P87F and was sold in two finishes — Lunar Light (white) and Dark Side of the Moon (black). Because it was highly configurable at checkout — spanning Core i7 or i9 processors, RTX 3070 or 3080 graphics, and up to a stunning 4K OLED panel — your exact combination of parts determines its resale value. This page covers the 15-inch m15 R4 specifically; if you have the older m15 R3 (2020, RTX 20-series), the larger m17 R4, or the mainstream Dell G15, those are different laptops with different values. Select your components using the tool above to view an instant cash offer, or trade it in toward your next device — more on our trade-in service below.

Which Alienware do you have? m15 R4 vs. the others

Several Alienware and Dell gaming laptops share a similar look, so the fastest way to be sure is the sticker on the bottom of the laptop. Look for the name Alienware m15 R4 or the regulatory code Reg. Model: P87F. Two quick checks confirm the R4 rather than the older R3: the R4 uses RTX 30-series graphics (RTX 3070 or 3080), while the 2020 m15 R3 (Reg. Model P79F) used RTX 20-series cards. And if your laptop simply says “Dell G15” rather than “Alienware,” it's a different, mainstream line and not covered here.

Display & audio

Display

All m15 R4 units use a 15.6-inch anti-glare panel, offered in three grades. Two are fast FHD (1920 × 1080) options — a 144Hz panel (300 nits, 100% sRGB, some with G-SYNC) or a competitive 300Hz esports panel. The premium option is a 4K UHD (3840 × 2160) 60Hz OLED panel with 400 nits, 100% DCI-P3, and Tobii eye-tracking. The 4K OLED commands a higher resale value, so note which one you have.

Audio

Dual tuned stereo speakers with a 3.5mm headphone/microphone combo jack and a dual-array digital microphone setup.

Ports & connectivity

Following Alienware's design, the heaviest connections route out the back to keep cords clear of your mouse hand. The R4 also keeps the proprietary Alienware Graphics Amplifier port for connecting an external desktop GPU.

Frequently asked questions

01 How do I confirm I have the Alienware m15 R4?
Turn the laptop over and read the label on the bottom panel. It will name the Alienware m15 R4 and show Reg. Model: P87F. To double-check inside Windows, type “About your PC” into the Start menu and look at the processor and graphics: a Core i7-10870H or i9-10980HK with an RTX 3070 or 3080 confirms the R4. If you instead see RTX 20-series graphics, you likely have the 2020 m15 R3 (Reg. Model P79F). Our Alienware model-number guide shows exactly where to look, and the general find-your-laptop-model-number guide covers reading your full specs in Windows.
02 Can I trade in an Alienware m15 R4 with cosmetic wear or hardware issues?
Yes. We buy the m15 R4 in every condition. Whether yours is spotless, shows scuffs or dents on the chassis, has a battery that no longer holds a charge, loud or failing fans, OLED burn-in or dead pixels, broken hinges, or won't power on at all, just set the matching condition grade in the tool above to lock in a firm cash value. Honest grading up front gives you the most accurate quote.
03 Should I wipe or remove my SSD before shipping?
Back up your personal files and game saves to an external drive or the cloud, then sign out of your Microsoft account and Windows profile before boxing the laptop. Since the m15 R4 can hold two drives, double-check you've backed up both if yours has a second SSD. You don't need to open the laptop or pull the M.2 drives yourself — our team runs certified, multi-pass data sanitization on every incoming drive. See our data erasure protocols for the full process.
04 Which configuration raises my m15 R4 trade-in value the most?
The GPU is the single biggest value driver: an RTX 3080 configuration commands a higher payout than an RTX 3070. After that, the Core i9-10980HK processor, the premium 4K OLED display, and larger memory (32GB) and storage (up to 4TB) all lift the offer. If you're upgrading rather than just cashing out, our trade-in service lets you apply that value directly toward your next device — a lot of sellers don't realize this is an option. You can see how the whole flow works on our How It Works page, and this guide walks through selling an Alienware step by step: How and Where to Sell a Used Alienware Laptop.
05 How fast do I get paid, and who covers shipping?
Once your Alienware m15 R4 reaches our facility and passes functional testing, payment is approved within two business days. You can choose a fast electronic payout — PayPal, Venmo, Zelle, or CashApp — or a physical check by mail. Your prepaid, insured shipping label is completely free from start to finish.
