HP ProBook 450 G5 A large 15.6-inch work screen with a number pad and an optional optical drive
The HP ProBook 450 G5 is HP's affordable 15.6-inch business laptop — a desktop replacement with a full number pad, an optional DVD writer and upgradeable memory. As a refurbished laptop from ITR Bulgaria, it is a practical choice for offices that want a large screen and still work with older software on physical media, without paying for the premium class.
Benefits
What makes the HP ProBook 450 G5 a sensible 15.6-inch choice as a refurbished laptop
A number pad for entering figures
The 15.6-inch chassis has room for a separate number pad. For an accountant or stock clerk entering numbers all day, that cuts hand movement compared with a 14-inch laptop without a numpad.
Optional DVD writer — rare today
Some configurations include a built-in optical drive. For offices with CD and DVD archives, or programs that ship only on disc, that saves the external USB drive that always goes missing in a drawer.
A 15.6-inch screen for desk work
The large work area is comfortable for spreadsheets, ERP/CRM windows and documents side by side. Suited to a workstation where the laptop mostly stays on the desk and is rarely carried around.
2× SO-DIMM up to 32 GB — upgrade later
Memory is DDR4 across two accessible slots — 2400 MHz with 8th Gen Intel Core and 2133 MHz with the other processor options. The machine can start modest and grow to 32 GB later — flexibility that isn't a given even on newer laptops with soldered RAM.
Optional NVIDIA GeForce 930MX
Some configurations ship with a discrete 930MX and 2 GB of memory — a light step up from the integrated UHD 620 for smoother work with images or external monitors. It depends on the specific unit.
Full-size RJ45 Ethernet
A built-in network port with no dongle. Practical in offices still running wired networks — you plug the cable straight in, without hunting for an adapter or a docking station.
48 Wh battery with HP Fast Charge
Fast charging to around 50% in half an hour with the HP-specified adapter, with the laptop off or in standby and no external devices connected. Enough to top the machine up between tasks, without keeping it plugged in all day.
Spill-resistant keyboard with optional backlight
A keyboard with spill resistance and an optional backlight. A spilled coffee mid-shift doesn't automatically mean a new laptop, and the optional backlight helps in a dimly lit office.
HP BIOSphere and Sure Start
Firmware protection with automatic BIOS recovery, plus TPM 2.0 and an optional fingerprint reader. Baseline business security that the ProBook 400 inherits from HP's higher series.
Affordable business class, refurbished
As a used laptop that has passed a technical audit and refurbishment, the HP ProBook 450 G5 puts a branded 15-inch chassis within reach — a sensible pick for equipping office staff on a tight budget.
HP ProBook 450 G5: the 15.6-inch entry ProBook from the optical-drive era
Some traits of a laptop look completely ordinary at purchase and only become interesting years later. On the HP ProBook 450 G5 that is the pairing of an optional DVD writer and a full number pad inside a standard 15.6-inch chassis. When it first appeared, this was normal for the more affordable business laptops — almost every 15-inch model had a bay for an optical drive and a numeric block to the right of the keyboard. Today both have all but vanished from the market, which turns this model into a practical choice wherever people still work with older software on physical media.
That one detail is what decides who the model is for. A great many accounting firms, municipal offices and repair shops still keep archives on CDs and DVDs, or run specialist programs that come only on disc and refuse to install any other way. For them an external USB DVD drive is one more thing that disappears in a drawer; a built-in optical drive has nowhere to get lost. Add the number pad to that — for someone entering invoices or stock figures all day, the separate numpad is the difference between hunting for digits along the top row and working without looking up from the document.
The G5 generation is also a fashion note in the line's biography. In 2018 HP gave the 400s their most visible change in years: shaving four millimeters off the height, dressing them in “Natural Silver” and setting aluminum around the keyboard — gestures borrowed from the pricier EliteBook's wardrobe. The message was unambiguous: affordable no longer means faceless. Every generation since has kept that self-assurance, and the second-hand buyer collects a side bonus — a machine that does not betray its age at first glance.
On the Intel Kaby Lake-R variants, under the hood sits a Core i3, i5 or i7 of the 8th generation, with integrated Intel UHD 620 graphics, and on some configurations a discrete NVIDIA GeForce 930MX with 2 GB of memory for lighter graphics work. Memory is DDR4 (2400 MHz on 8th Gen) across two SO-DIMM slots, upgradeable to 32 GB after purchase, and a 48 Wh battery with HP Fast Charge returns roughly half a charge in about half an hour with the laptop off or in standby, using the HP-specified adapter and with no external devices connected. The ProBook line itself exists for a clear reason: HP keeps the EliteBook for corporate customers with bigger budgets, while the ProBook 400 is the affordable business class for small companies, schools and administrations that want a branded machine without paying for a premium chassis and the full security stack. You can see that in the construction too — an aluminium lid over a polymer base, tested to MIL-STD-810G. Not as polished as an EliteBook, but built to take the daily knocking around in a bag and the moving between desks without creaking after the first year.
The main trade-off comes from the class and the size. At around 2.0 kg the HP ProBook 450 G5 is a desktop replacement, not a machine for daily carrying — if you move the laptop constantly, the 14-inch HP ProBook 440 G5 makes more sense. There is no Thunderbolt either, but the USB-C port with DisplayPort and charging supports single-cable docking, including external monitors, with a compatible dock. Among the direct 15.6-inch alternatives, the Dell Latitude 3590 covers the same entry class but without a built-in optical drive, while the Lenovo ThinkPad E580 is the 15.6-inch entry ThinkPad with a number pad and a TrackPoint; if you need an even larger screen, the HP ProBook 470 G5 is the 17.3-inch option from the same generation. As a refurbished laptop from the business class, the ProBook 450 G5 has a clear logic: a branded 15-inch chassis with a numpad and a DVD option, put through a technical audit and refurbishment, delivered with a real warranty from ITR Bulgaria — a used business laptop that solves a specific job rather than just being cheap.
Who it's a good fit for
Scenarios where the HP ProBook 450 G5 makes the most sense
Offices with archives on optical media
An accounting firm or administration that keeps years of records on CDs and DVDs. With the optional built-in optical drive, the old archives open and re-burn directly, without digging out an external USB drive every time a single disc is needed.
Working with older specialist software
A workshop, lab or design office whose specialist software installs only from disc and accepts nothing else. Here the built-in DVD writer isn't a convenience — it's the condition for the program to run on the machine at all.
A desktop replacement with a large screen
A workstation where one machine does the job of a desktop while taking up less room. The 15.6-inch screen and the number pad give a desk-like feel, and when needed the laptop still tucks away in a drawer.
Admin work with heavy number entry
An operator moving invoices, payroll or stock quantities into an ERP system all day. The separate numeric block makes data entry faster and less tiring than on a 14-inch laptop without a numpad.
Model highlights
15.6″ 16:9 display, touch option
Available with an HD TN panel or FHD IPS anti-glare (1920×1080), and on some units an HD touch panel. Brightness around 220–250 nits — aimed at indoor office work.
Intel Kaby Lake-R variants + optional 930MX
Variants with a Core i3-8130U, i5-8250U or i7-8550U of the 8th generation with integrated Intel UHD 620. On some configurations, a discrete NVIDIA GeForce 930MX 2 GB for lighter graphics work.
DDR4, 2× SO-DIMM up to 32 GB
Two accessible memory slots, upgradeable to 32 GB. The M.2 NVMe SSD is replaceable as well — the core components for refurbishment stay open to service.
Optional DVD writer + SD reader
A built-in optical drive on some configurations — a feature that has all but disappeared from modern laptops. Plus an SD reader for camera cards and peripherals.
Number pad with spill resistance
A full keyboard with a separate numeric block, optional backlight and spill resistance. The 15.6-inch format makes the numpad standard rather than optional — a rarity in the smaller classes.
Broad port set, no Thunderbolt
3× USB-A (two USB 3.1 Gen 1 and one USB 2.0), HDMI 1.4b, a full-size RJ45 Ethernet, an audio jack and a Kensington slot. Thunderbolt is absent, but USB-C supports single-cable docking with a compatible dock.
48 Wh battery + HP Fast Charge
A 3-cell 48 Wh battery with fast charging to around 50% in half an hour with the laptop off or in standby, using the HP-specified adapter and with no external devices connected. Enough for a working day at the desk near an outlet, plus quick top-ups between tasks.
HP BIOSphere, Sure Start, TPM 2.0
Firmware protection with automatic BIOS recovery, HP Client Security and TPM 2.0. An optional fingerprint reader. Baseline business security in the affordable ProBook class.

Additional information
Where this model fits in the series ▼
The HP ProBook 450 G5 is part of the ProBook 400 series — HP's entry business line. This is the affordable business class HP positions below the premium EliteBook 800 and the mainstream ProBook 600 series. The ProBook 400 delivers the core business functions and the branded build, without the full HP Wolf Security stack or the EliteBook's premium chassis. In that role it competes directly with the Dell Latitude 3000 and the Lenovo ThinkPad E.
Within the G5 generation, the ProBook 400 comes in four sizes: the HP ProBook 430 G5 (13.3″, compact), the HP ProBook 440 G5 (14″, balanced), the HP ProBook 450 G5 (15.6″, a large screen with a number pad) and the HP ProBook 470 G5 (17.3″, maximum screen area). The 450 is the 15-inch desktop replacement in the group — with room for a numpad and an optional optical drive.
Within its own line, the model is succeeded by the HP ProBook 450 G6 (8th-gen Whiskey Lake refresh, a thinner chassis and an updated design). The G5 remains widely available second-hand thanks to the large number of units sold into office and education use.
The HP ProBook 450 G5 is not ideal if… ▼
- You carry the laptop every day — at around 2.0 kg this is a desktop replacement, not a machine for frequent transport. For mobile work, look at the 14-inch HP ProBook 440 G5 or a lighter model.
- You need Thunderbolt — the HP ProBook 450 G5 has no Thunderbolt, but its USB-C port supports single-cable docking, including external monitors, with a compatible dock.
- You want a premium chassis and full business security (B&O audio, a Sure View privacy panel, the complete Wolf Security suite) — those live in the EliteBook 800 series, not the entry ProBook 400.
- You count on discrete graphics, an FHD screen, a DVD writer or a fingerprint reader as guaranteed — all of these are configuration-dependent. It's worth checking the specific unit.
- You want the 14-inch format (HP ProBook 440 G5) or the 17.3-inch (HP ProBook 470 G5) — these are the direct size alternatives from the same generation.
Choosing the right size and construction ▼
13.3-inch class (HP ProBook 430 G5): the most compact in the line, without a numeric block. For users who put a smaller bag footprint ahead of screen area.
14-inch class (HP ProBook 440 G5): the balanced size for mobile work — lighter than the 450, but with no built-in room for a numpad or an optical drive.
15.6-inch class (HP ProBook 450 G5): a large screen, a full keyboard with a numeric block and an optional DVD writer. A desktop replacement for work mostly at the desk.
17.3-inch class (HP ProBook 470 G5): the largest screen area of the generation, for working with several windows at once or spreadsheets at a larger size. Heavier and even more stationary.
Construction: the HP ProBook 450 G5 has an aluminium lid over a polymer base, tested to MIL-STD-810G. Around 21.6 mm thick, in natural silver. A sturdy working chassis for daily office use, without premium polish.
Alternative models ▼
Within HP:
HP ProBook 440 G5 — the 14-inch option from the same generation. Lighter and easier to carry, but without a numeric block or built-in room for an optical drive. The pick for mobile work.
HP ProBook 470 G5 — the 17.3-inch format. Even more screen area for spreadsheets and several windows, but a heavier desktop replacement. For people who never carry the machine.
HP ProBook 450 G6 — the next generation. A thinner chassis, an updated design and platform. A more current choice, usually at a higher price as a refurbished laptop.
HP ProBook 650 G4 — a step up toward the mainstream HP ProBook 600 class. Better construction and a richer set of business functions, at a higher position in the line.
Cross-brand alternatives (15.6″, entry business class, Intel 8th Gen):
Dell Latitude 3590 — the 15.6-inch entry Dell Latitude of the period. It covers the same office role, but without a built-in optical drive. A similar class and target group.
Lenovo ThinkPad E580 — the 15.6-inch entry Lenovo ThinkPad. It has a number pad and the classic TrackPoint in the middle of the keyboard. An alternative for those who prefer the Lenovo ThinkPad layout.
Note: don't compare the HP ProBook 450 G5 with the HP EliteBook 850 G5 — the HP EliteBook 850 G5 belongs to a different, premium business class with a higher price and a different target group.
Refurbished by ITR Bulgaria: what value do you get? ▼
The HP ProBook 450 G5 is convenient to refurbish for a practical reason: HP kept the core components accessible to service. The bottom cover comes off with standard screws, memory sits in two SO-DIMM slots, and the M.2 NVMe SSD is replaceable. That makes the technical audit, cleaning and parts replacement clear and free of surprises.
On top of that comes the model's wide deployment in office and education environments — spare parts, batteries and chargers are easy to find on the market even years after its release. That makes the HP ProBook 450 G5 a practical used laptop with dependable support over a long period. After refurbishment, the model is prepared for repeat business use and arrives with a real warranty and support from ITR Bulgaria.
Frequently asked questions ▼
Is the HP ProBook 450 G5 a good choice as a used laptop?
For a specific use — yes. This is a branded 15.6-inch business laptop with a number pad and an optional optical drive, and it makes the most sense for offices working with older software or disc archives. As a refurbished laptop from the entry business class, it gives access to a reliable office machine at an affordable price. If you need a light laptop for frequent transport, a 14-inch model is the better look.
Does the HP ProBook 450 G5 have a DVD writer and a number pad?
The number pad (numpad) is standard on the 15.6-inch chassis. The built-in DVD writer is optional — present on some configurations, not on every unit. If the optical drive matters to you, confirm it for the specific device before buying.
What's the difference between the HP ProBook 450 G5 and the HP ProBook 440 G5?
The main difference is size. The HP ProBook 450 G5 is 15.6-inch, with a full keyboard including a numeric block and the option of a built-in optical drive — a desktop replacement. The HP ProBook 440 G5 is 14-inch, lighter and easier to carry, but without a numpad and without room for a DVD. The 8th Gen Intel Core variants share a similar platform and business functions.
Can the memory and storage be upgraded?
Yes. Memory is DDR4-2133/2400 across two SO-DIMM slots, expandable to 32 GB. Storage is an M.2 NVMe SSD and is also replaceable. That gives real headroom for upgrades after purchase, without replacing the whole machine.
Is it suitable for equipping office staff?
Yes — it's one of the core roles of the ProBook 400 series. The affordable business class, large screen and numpad make it practical for administrative and accounting workstations. As a refurbished business laptop from ITR Bulgaria it comes with a warranty, which makes equipping staff in volume easier on a modest budget.
