The Dell XPS 15 9550 launched in 2015 as the first redesigned XPS 15, built around Intel's 6th-generation Skylake processors and a machined-aluminum, carbon-fiber chassis with one of the thinnest bezels on the market at the time. It was aimed at people who wanted a compact 15-inch machine with real graphics headroom for photo and video work, not just a spreadsheet laptop. This page covers the non-touch Full HD panel version specifically. It still holds value because the build quality has aged well, the internals are genuinely serviceable, and a well-kept unit with the optional GTX 960M is still useful for light creative work or a reliable secondary machine. Pick your processor and condition in the tool above for an instant cash offer, see how the process works, or go straight to sell your Dell laptop if this isn't the exact model you have.

Confirm you have the XPS 15 9550

The quickest check is inside Windows. Open Settings → System → About, or run dxdiag from the Run box (Windows key + R) and read the "System Model" line. You can cross-check against the service tag printed on the sticker on the underside of the laptop. If you want a broader walkthrough for Dell hardware, our guide to finding your Dell model number covers where else to look.

XPS 15 9550

  • System model reads "XPS 15 9550" in dxdiag or msinfo32
  • Bottom panel shows regulatory model P56F alongside the service tag
  • BIOS setup (F2 at boot) lists the same model string

FHD non-touch panel

  • Settings → Display shows a native resolution of 1920x1080
  • Screen has a matte, anti-glare finish with no touch response
  • No touch controller listed under Device Manager

Prefer a visual check? The lid and base are machined aluminum with a silver finish, the palm rest is black carbon-fiber weave, and the webcam sits in the lower bezel near the hinge rather than above the screen.

  • The i7 configuration is the one buyers pay more attention to

Graphics

  • Intel HD Graphics 530 on base configurations
  • Optional NVIDIA GeForce GTX 960M with dedicated GDDR5 memory
  • A working GTX 960M configuration moves resale value the most

  • Drive sits behind the same service panel as the RAM slot

Display & audio

15.6-inch Full HD (1920x1080) IPS panel with a matte, anti-glare coating and Dell's InfinityEdge slim bezel. No touch digitizer on this variant.

Stereo speakers flank the keyboard, firing upward through the deck. A combo headset jack sits on the right edge alongside a Realtek audio codec.

Battery, build & more

84Wh battery, the larger of the two capacities Dell offered on this chassis. The non-touch FHD variant has room for this size where the UHD touch version does not, which gives it a real runtime advantage.

About 4 pounds and roughly 0.66 inch thick at its slimmest point, noticeably lighter than the touchscreen configuration of the same laptop.

Silver machined-aluminum lid and base, black carbon-fiber weave palm rest. Originally shipped with Windows 10; this chip generation does not have official Windows 11 support.

Well-documented issues on this generation include a Dell battery replacement program for early swelling batteries and occasional coil whine under GPU load. Worth checking battery health before you box it up.

Frequently asked questions

01 How do I find the model number and exact configuration?
Open Settings → System → About in Windows, or run dxdiag from the Run box (Windows key + R), and read the System Model field. It should read "XPS 15 9550." The processor, RAM, and storage are listed on the same screen. The service tag on the bottom panel confirms the exact factory build if you register it on Dell's support site. For a step-by-step walkthrough with photos, see our Dell model number guide.
02 How do I tell it apart from the UHD touchscreen XPS 15 9550?
Check the display resolution and whether the screen responds to touch. This non-touch model runs at 1920x1080 with a matte anti-glare finish and no touch response, while the other variant is a 3840x2160 glossy touch panel. The touch version is also slightly heavier and carries a smaller 56Wh battery instead of the 84Wh unit found here. If Settings → Display shows anything above 1080p, or tapping the screen produces a response, it's the other configuration.
03 Can I sell it with damage, a weak battery, or a locked account?
Yes. A cracked screen, a battery that no longer holds a charge, or a unit that won't power on can still be sold; the condition picker above adjusts the offer to match. What has to be resolved first is any account lock. Remove your Microsoft account from the machine, sign out of any linked services, and suspend BitLocker if it's enabled so the drive is accessible for testing. A device that's still tied to your Microsoft account cannot be processed even if the hardware itself is in good shape.
04 What raises the trade-in value the most?
A working i7-6700HQ with the GTX 960M and minimal cosmetic wear brings the strongest offer. Beyond configuration, the biggest swing factors are a battery that still holds a reasonable charge, a screen and hinge free of cracks or heavy scuffing, and having the original charger included. A unit that boots cleanly to Windows with no account lock will always process faster and grade higher than one that doesn't.
05 How do I erase it, remove my account, and get paid?
Go to Settings → System → Recovery → Reset this PC and choose "Remove everything." Before that finishes, sign out of and remove the device from your Microsoft account under Settings → Accounts, and suspend or decrypt BitLocker if you turned it on. Once the reset completes, the drive is wiped and the account is no longer tied to the hardware. Full steps, including how to handle an encrypted drive, are in our data erasure protocols. Shipping is free and insured, and payment goes out after inspection by PayPal, Venmo, Zelle, CashApp, or check.
