The HP ProBook 450 G6, released in 2019, is a 15.6-inch business notebook from HP's entry-level professional line — the 15-inch member of the ProBook 400 G6 family. Built on 8th-generation Intel "Whiskey Lake" processors in a MIL-STD-810G tested chassis, it was sold largely to corporations, schools, and small businesses, so many units are now reaching the resale market as organizations refresh their hardware. If you're deciding where to offload an old work machine, our trade-in service buys these directly for cash — see our guide on the HP laptop trade-in process. Because the 450 G6 was configured heavily at the corporate-order level, your exact processor, memory, storage, and graphics choices determine its final resale price. Select your components using the tool above to view an instant cash offer for your specific device.

Before you start: HP's ProBook 450 naming spans several near-identical 15.6-inch generations. The G6 is the 2019, 8th-gen Intel model. The later 450 G7 (10th-gen, 2020) and 450 G8 (11th-gen, 2021) look almost identical but are separate devices with their own quote pages. The quickest way to tell them apart is the processor — a Core i5-8265U or i7-8565U means you have the G6. Confirm the generation before configuring so your offer reflects the right machine.

Core hardware configurations

Processor (CPU)

  • Intel Core i3-8145U — 2 cores, 4 threads, up to 3.9 GHz
  • Intel Core i5-8265U — 4 cores, 8 threads, up to 3.9 GHz
  • Intel Core i5-8365U (vPro) — 4 cores, 8 threads, up to 4.1 GHz
  • Intel Core i7-8565U — 4 cores, 8 threads, up to 4.6 GHz
  • Entry Intel Pentium 5405U and Celeron options also shipped in some regions
  • All are 8th-gen "Whiskey Lake" 15W U-series chips

Graphics (GPU)

  • Integrated Intel UHD Graphics 620 (on Core i3/i5/i7 models)
  • Integrated Intel UHD/HD Graphics 610 (on Pentium/Celeron models)
  • Optional NVIDIA GeForce MX130 or MX250 (2GB GDDR5) discrete graphics
  • Graphics are integrated into the CPU on most units — there is no GPU upgrade path

Memory (RAM)

  • DDR4-2400 across two SO-DIMM slots
  • Factory options of 4GB, 8GB, or 16GB
  • User-upgradable to a maximum of 32GB via the bottom access panel
  • Note: single-stick units run in single-channel mode, which limits the discrete GPU — a matched second module enables faster dual-channel operation

Storage

  • M.2 PCIe NVMe or SATA SSD (typically 128GB / 256GB / 512GB)
  • Plus an optional 2.5-inch SATA bay for an additional HDD (up to 1TB) or second SSD
  • Both bays are accessible and serviceable via the bottom panel
  • Optional Intel Optane memory acceleration on some builds

Display & audio

Display

15.6-inch panels in two main tiers: a basic HD (1366 × 768) SVA anti-glare panel (220 nits, with weaker viewing angles), and a much better FHD (1920 × 1080) UWVA IPS-class anti-glare panel (220 nits, 67% sRGB). The FHD panel is the value-driving screen choice at resale; a touch FHD option was also offered.

Audio

Dual integrated stereo speakers with a dual-array microphone, tuned for clear voice on conference calls.

Ports & connectivity

A note for this generation: the USB-C port is the slower USB 3.1 Gen 1 standard (with DisplayPort 1.2 and Power Delivery), there's a legacy USB 2.0 port, and HDMI is the older 1.4b. Unlike the later G8, this model keeps a full-size SD card reader.

Right Side
  • 1× USB-C 3.1 Gen 1 (DisplayPort 1.2 + USB Power Delivery)
  • 2× USB-A 3.1 Gen 1 (5Gbps)
  • 1× HDMI 1.4b
  • 1× SD media card reader
Left Side
  • 1× USB-A 2.0 (powered port)
  • 1× RJ-45 Gigabit Ethernet
  • 1× 3.5mm headphone/microphone combo jack
  • 1× Power adapter input (barrel DC-in)
  • 1× Nano security lock slot
  • 1× Nano SIM slot (optional, WWAN models)

Intel Wireless-AC 9560 (Wi-Fi 5) Bluetooth 5.0 Optional 4G LTE WWAN

Battery, build & more

Battery & charging

3-cell 45 Whr battery rated for roughly 8 hours of general use, with HP Fast Charge (about 50% in 30 minutes). Charged over the barrel DC-in jack. Battery health is a common condition factor on fleet-returned units, so grade it honestly above.

Camera & mic

Integrated 720p HD webcam with a dual-array digital microphone. An IR camera for Windows Hello facial sign-in was available on some builds.

Keyboard & security

Spill-resistant keyboard with a numeric keypad (backlight optional). Security hardware includes TPM 2.0, HP BIOSphere Gen4, an optional fingerprint reader, and an optional IR camera.

Build & durability

Ultraslim chassis with a 3D-forged aluminum keyboard deck and a 180°-opening hinge, tested to MIL-STD-810G standards.

Weight

≈ 2.0 kg (4.4 lb), depending on configuration.

Dimensions

365 × 257 × 19.8 mm (14.37" × 10.11" × 0.78").

Frequently asked questions

01 How do I confirm I have the ProBook 450 G6 and not a G7 or G8?
These three generations share an almost identical 15.6-inch body, so the processor is the giveaway: an 8th-gen chip (i3-8145U, i5-8265U/8365U, i7-8565U) means the G6; 10th-gen (i5-10210U) means the G7; and 11th-gen (i5-1135G7) means the G8. The exact "G6" generation is printed on the regulatory label on the bottom cover and appears in Windows under Settings → System → About. For step-by-step help, see our HP model-number guide or the general how to find your laptop model number walkthrough.
02 Can I upgrade the RAM and storage, and does that get me more cash?
Yes — the 450 G6 is very serviceable. It has two SO-DIMM slots (upgradable to 32GB of DDR4-2400) plus both an M.2 SSD slot and a 2.5-inch SATA bay, so you can run an SSD and an HDD together. For your quote, just report what's currently installed; 16GB of RAM and a 512GB SSD raise your offer above the common 8GB/256GB baseline. The discrete MX130/MX250 also benefits from running RAM in dual-channel (two matched sticks).
03 This was a work laptop — how do I make sure corporate data is wiped before I sell?
First, confirm the device has been released from any corporate management — MDM enrollment, BIOS passwords, or HP Sure Admin — since a locked machine can't be resold; check with your IT department if you're unsure. Back up anything you need, sign out of your Microsoft and other accounts, and you don't need to remove the drive yourself. Once your laptop reaches us, our team runs certified multi-pass data sanitation on every drive. Full details are on our data erasure protocols page.
04 Which configurations raise my ProBook 450 G6 trade-in value the most?
On this older business model, the processor, RAM, and storage drive most of the value. A Core i7-8565U with 16GB of RAM and a 512GB SSD sits well above the entry i3 / 4GB / HDD builds. The optional NVIDIA MX130/MX250 graphics and the FHD IPS display (rather than the basic HD panel) also lift the figure. Good cosmetic condition and a healthy battery matter too; our blog on selling your laptop as a first-time seller covers how to prep for the best offer.
05 How fast do I get paid, and what payment methods are available?
After your ProBook arrives and our intake team finishes functional testing, payment is approved within about two business days. You can choose fast electronic options — PayPal, Venmo, Zelle, or Cash App — or a traditional mailed check. Inbound shipping is free and fully insured with a prepaid label. If you're clearing several units from an office refresh, we also have a bulk selling program for lots of five or more.
