The HP ProBook 455 G7, released in 2020, is the 15.6-inch AMD-powered model in HP's entry-level professional ProBook line — the Ryzen counterpart to the Intel-based ProBook 450 G7. It was notable as one of the first HP business laptops to run AMD's then-new Ryzen 4000 "Renoir" processors, delivering a big multi-core jump over the prior generation in an aluminum, MIL-STD-810H tested chassis. Sold heavily to corporations, schools, and small businesses, many units are now reaching the resale market as organizations refresh their fleets. 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 455 G7 was configured heavily at the corporate-order level, your exact processor, memory, and storage 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 — Intel vs AMD matters here. The 455 G7 is the 15.6-inch AMD Ryzen model. Its near-identical Intel twin is the 450 G7 (same chassis, 10th-gen Intel Core inside), and there's a 14-inch AMD sibling, the 445 G7. These look almost the same but are separate devices with their own quote pages. The quickest tell is the processor: an AMD Ryzen 3/5/7 4000-series chip (4300U / 4500U / 4700U) means you have the 455 G7. Confirm this before configuring so your offer reflects the right machine.

Core hardware configurations

Processor (CPU)

  • AMD Ryzen 3 4300U — 4 cores, 4 threads, up to 3.7 GHz
  • AMD Ryzen 5 4500U — 6 cores, 6 threads, up to 4.0 GHz
  • AMD Ryzen 7 4700U — 8 cores, 8 threads, up to 4.1 GHz
  • PRO variants (Ryzen 5 PRO 4650U / Ryzen 7 PRO 4750U) shipped on managed-fleet orders
  • These are Ryzen 4000 "Renoir" U chips built on the Zen 2 architecture (15W)

Graphics (GPU)

  • Integrated AMD Radeon Graphics (Vega-based: Vega 5 / 6 / 7 / 10 depending on CPU tier)
  • There is no discrete graphics option on this model
  • Graphics are integrated into the CPU — there is no GPU upgrade path

Memory (RAM)

  • DDR4-3200 across two SO-DIMM slots, supporting dual-channel
  • Factory options of 8GB or 16GB
  • User-upgradable to a maximum of 32GB via the bottom panel
  • Note: single-stick units run in single-channel mode — adding a matched second module improves the integrated Radeon graphics

Storage

  • M.2 PCIe NVMe or SATA SSD (typically 128GB / 256GB / 512GB)
  • Plus a 2.5-inch SATA bay for an additional HDD (up to 1TB) or second SSD
  • Both bays are accessible after removing the bottom panel (no separate maintenance hatch)

Display & audio

Display

15.6-inch panels in two main tiers: a basic HD (1366 × 768) SVA anti-glare panel, and a better FHD (1920 × 1080) IPS anti-glare panel (250 nits, ~50% sRGB). An optional HP Sure View privacy panel was offered on select builds. The FHD IPS panel is the value-driving screen choice at resale.

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 USB 3.1 Gen 1 (with DisplayPort and Power Delivery), there's a legacy USB 2.0 port, and HDMI is 1.4b. This older-chassis model keeps a full-size SD card reader and the 2.5-inch drive bay. There is no Thunderbolt.

Right Side
  • 1× USB-C 3.1 Gen 1 (DisplayPort + USB Power Delivery)
  • 2× USB-A 3.1 Gen 1 (5Gbps)
  • 1× HDMI 1.4b
  • 1× RJ-45 Gigabit Ethernet
  • 1× Power adapter input (barrel DC-in)

Battery, build & more

Battery & charging

3-cell 45 Whr HP Long Life battery with strong real-world runtime (around 12 hours of light use) and HP Fast Charge (about 50% in 30 minutes). Charged over the barrel DC-in jack; USB-C charging is also supported. Battery health is a common condition factor on fleet-returned units, so grade it honestly above.

Camera & mic

Integrated 720p HD webcam with a privacy camera shutter and a dual-array microphone. An optional 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, an optional fingerprint reader, HP Sure Sense, HP Sure Start, and the privacy camera shutter.

Frequently asked questions

01 How do I confirm I have the AMD ProBook 455 G7 and not a 450 G7 or 445 G7?
Check the processor brand and screen size. The 455 G7 is 15.6-inch with an AMD Ryzen 4000-series chip (4300U / 4500U / 4700U); the 450 G7 is the same-size Intel model (10th-gen Core), and the 445 G7 is the 14-inch AMD version. You can see the CPU in Windows under Settings → System → About, and the exact "ProBook 455 G7" name is printed on the regulatory label on the bottom cover. 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 455 G7 is serviceable once the bottom panel is off. It has two SO-DIMM slots (upgradable to 32GB of DDR4-3200) plus both an M.2 SSD slot and a 2.5-inch SATA bay, so an SSD and an HDD can run together. For your quote, just report what's installed; 16GB of RAM and a 512GB SSD raise your offer above the common 8GB/256GB baseline, and running RAM in dual-channel (two matched sticks) also helps the integrated Radeon graphics.
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 455 G7 trade-in value the most?
On this model the processor, RAM, and storage drive most of the value, since there's no discrete GPU. The 8-core Ryzen 7 4700U (or Ryzen 7 PRO 4750U) with 16GB of RAM and a 512GB SSD sits well above the entry Ryzen 3 / 8GB / HDD builds. The FHD IPS display rather than the basic HD panel, plus a fingerprint reader, also help. 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.
