HP ProBook 640 G5 The 14-inch mainstream ProBook above the entry 400 series
A mainstream business laptop from the middle rung of HP's lineup, above the entry ProBook 400, below the premium EliteBook 800. A 14-inch aluminium chassis, USB-C with DisplayPort and charging, and upgradeable SO-DIMM memory. As a refurbished business laptop from ITR Bulgaria, it gives you the full ProBook class without the premium price.
Benefits
Why the HP ProBook 640 G5 is a sensible mainstream buy as a refurbished business laptop
A step above the entry 400 series
ProBook 600 is the upper half of the ProBook range, with a sturdier build and richer connectivity than the entry 400, without the premium EliteBook 800 price. The middle rung of HP's business ladder.
Memory you can swap yourself
Two SO-DIMM slots take up to 64 GB of DDR4, and the memory is not soldered. For a company that buys once and keeps a machine for years, that is an easy upgrade that extends its working life.
USB-C docking: one cable
A single USB-C port with DisplayPort and Power Delivery handles a compatible docking station, external displays, data transfer up to 5 Gbit/s and charging over the same cable. The side connector for the HP UltraSlim Docking Station adds a connection the entry ProBook 400 does not offer.
Full-size RJ45 + 3× USB-A
A classic RJ45 jack connects straight to the corporate network without an adapter, plus three USB-A 3.1 ports and HDMI. Handy in offices that still run wired networks and older peripherals.
Optional IR camera and Windows Hello
On select configurations, a 720p camera with an IR sensor for face sign-in instead of a password. Useful for hybrid workers who start the day straight in a video call.
48 Wh battery with fast charging
HP Fast Charge returns about 50% in 30 minutes, roughly a lunch break between two meetings. Enough to avoid hunting for a power outlet in the middle of the working day.
Aluminium chassis, MIL-STD-810G
The chassis is aluminium and passes MIL-STD-810G durability testing. A machine built to survive years of daily moves between desk, bag and meeting room.
Part of HP Wolf Security
HP Sure Start (BIOS protection and recovery), Sure Sense, Sure Click, BIOSphere Gen5 and TPM 2.0. Hardware-hardened security that is rare on entry machines at a similar price.
Easy access to the internals
The M.2 NVMe SSD and SO-DIMM modules are replaceable with a few screws. That makes the technical audit and refurbishment straightforward, part of why the HP ProBook 640 G5 is a sensible used laptop.
Sensible value as a refurbished laptop
As a used laptop that has passed a technical audit and refurbishment, the HP ProBook 640 G5 gives access to the full mainstream ProBook class at the price of a used business laptop.
HP ProBook 640 G5: the 14-inch mainstream ProBook above the entry 400 series
HP's business range is a ladder with three clear rungs. At the top sits the EliteBook 800, the premium line with the full Wolf Security stack, Bang & Olufsen sound and privacy panels. At the base is the ProBook 400, the entry series for companies just moving to a branded business laptop. Between them is the ProBook 600: the mainstream tier, which HP builds sturdier and better connected than the 400 series, without the premium EliteBook price. The HP ProBook 640 G5 is the 14-inch member of that middle rung, and that is exactly why it makes such a sensible buy as a refurbished laptop: you get more than entry class without paying for a flagship.
The ProBook line exists for a specific reason. Once the EliteBook had established itself as the premium corporate standard, HP needed a series for the far larger group of companies, the ones that want a branded, manageable business laptop but cannot justify a premium price for every desk. So the ProBook arrived: the affordable, mainstream alternative to the EliteBook. Over time the range itself split in two: the 400 series took the entry level, and the 600 series became its upper half: machines HP describes as thinner and tougher than their predecessors, with an "almost-EliteBook" feel at a lower price. The HP ProBook 640 G5 inherits exactly that role, a ProBook whose build and features sit closer to the HP EliteBook 840 G6 than to the entry HP ProBook 440 G6.
Under the hood the platform is Intel Whiskey Lake-U: U-series Core processors with integrated UHD Graphics 620 and vPro options for companies that manage their machines centrally. For everyday office work (a browser with dozens of tabs, Excel, ERP and CRM systems, video calls) that is enough of a foundation in the right configuration. Two things, though, lift the HP ProBook 640 G5 above the entry class. First, the memory: two SO-DIMM slots take up to 64 GB of DDR4 that you can swap yourself, a rarity for people who buy once and use for years. Second, the connectivity: a single USB-C port with USB 3.1 Gen 1, DisplayPort 1.2 and Power Delivery handles a compatible docking station, up to two external displays depending on the dock and data transfer up to 5 Gbit/s over the same cable that charges the laptop, while the full-size RJ45 plugs the machine straight into the corporate network without an adapter. The 48 Wh battery with HP Fast Charge returns about 50% in half an hour, roughly a lunch break between two meetings.
The cores in this machine fulfill a sixty-year-old prophecy. On April 19, 1965, Electronics magazine published an article by Gordon Moore — then a director at Fairchild — who drew a line through just five data points and predicted: the number of components on a chip would double periodically, and the cost of computation would fall. “Moore's Law” became the industry's self-fulfilling schedule — engineers chased it for decades because everyone believed in it. The four cores in an affordable ProBook with a Core i5 or i7 are a late installment on that five-point promise.
This is exactly where the difference from the entry ProBook 400 shows. The HP ProBook 440 G6 sits on the same Whiskey Lake-U base, and also has a USB-C port with DisplayPort and Power Delivery. The 640 G5 adds a side connector for the HP UltraSlim Docking Station, the option of an IR camera for Windows Hello (face sign-in instead of a password for hybrid workers) and a sturdier build. Against the competition the choice comes down to priorities: the direct rival, the Dell Latitude 5400, runs the same platform but leans on a larger 68 Wh battery for longer time unplugged, while the 640 G5 answers with Thunderbolt and upgradeable memory. The Lenovo ThinkPad L490, the mainstream 14-inch ThinkPad, brings a fuller ThinkShield package and the classic ThinkPad keyboard with TrackPoint, if that matters more to the team.
An honest word on the trade-off: the HP ProBook 640 G5 is not an ultraportable. The aluminium chassis starts at around 1.71 kg, heavier than the premium 14-inch machines, because this is a mainstream chassis, not a flagship. Graphics are integrated UHD 620 or an optional Radeon 540X with 2 GB GDDR5 (for video editing or 3D work, look at the HP ZBook line). And while it carries a solid slice of HP Wolf Security (Sure Start, Sure Sense, Sure Click, BIOSphere Gen5), it is not the full premium EliteBook suite, and the audio is DTS:X Ultra rather than Bang & Olufsen. For the companies it was built for, those that have outgrown the entry class but lack the budget for a flagship on every desk, the trade-off is logical. As a refurbished business laptop from ITR Bulgaria, audited and refurbished, the ProBook 640 G5 gives access to the full mainstream ProBook class at the price of a used laptop, with upgradeable memory that extends its working life, and a real warranty.
Who it suits
Scenarios where the HP ProBook 640 G5 makes the most sense
A company that has outgrown the entry class
A business that started on basic machines and now needs more (USB-C docking or a side-mounted HP UltraSlim dock, a sturdier build, swappable memory) but is not yet ready for an EliteBook budget on every employee. The HP ProBook 640 G5 is the middle step made for that exact moment.
Hybrid work with video calls
An employee who alternates home and office and often opens the day in Teams or Zoom. With an IR camera configuration they sign in by face in a second, while the dual microphones and DTS:X Ultra keep the call clear.
A standardised corporate fleet
An IT department equipping employees at volume and keeping a single image across all machines. vPro options allow remote management, and the familiar ProBook platform makes support and parts replacement easier.
Mobile office staff
People who carry the machine between offices and client meetings. The 14-inch size and the 50%-in-30-minutes charge, with the laptop off or in standby and an adapter of at least 65 W, keep them moving, and the full-size RJ45 plugs the laptop into a wired network where Wi-Fi falls short.
Model highlights
14″ 16:9 display with several options
Configurations range from HD to FHD IPS anti-glare, and on some units a high-brightness FHD IPS or a Sure View Gen3 privacy panel (nominally 1000 nits in the non-touch version). Always check the specific unit.
Intel Whiskey Lake-U + UHD 620
U-series Core processors (i3/i5/i7, some with vPro) with integrated UHD Graphics 620. A mature, well-understood platform for office tasks, the browser and video calls.
2× SO-DIMM DDR4-2400 up to 64 GB
The memory is not soldered, with two slots for modules totalling up to 64 GB. An easy post-purchase upgrade that most thin rivals of the era did not allow.
USB-C + 3× USB-A + RJ45
1× USB-C with USB 3.1 Gen 1 (5 Gbit/s), DisplayPort 1.2 and Power Delivery for compatible docking and displays, three USB-A 3.1, HDMI 1.4b and a full-size RJ45. Modern and classic connectivity in one body.
48 Wh battery + HP Fast Charge
A 3-cell 48 Wh battery with HP Fast Charge, about 50% in 30 minutes with the laptop off or in standby and an adapter of at least 65 W. A quick top-up between two meetings, without a long wait at the outlet.
HP Wolf Security components
HP Sure Start (BIOS protection and self-recovery), Sure Sense, Sure Click, BIOSphere Gen5 and Sure Run, plus TPM 2.0: corporate security at the mainstream tier.
Options: IR, fingerprint, 4G LTE, NFC
Depending on configuration: an IR camera for Windows Hello, a fingerprint reader, smart card, NFC and a 4G LTE WWAN module. Not present on every unit; check the specific one.
Spill-resistant HP keyboard
A spill-resistant keyboard with optional backlighting, in a 14-inch layout without a number pad, designed for comfortable typing through a full day of documents and email.

Additional information
Where does the HP ProBook 640 G5 fit in the series? ▼
The HP ProBook 640 G5 belongs to the ProBook 600 series, HP's mainstream business line. In the bigger picture HP arranges its business laptops in three tiers: ProBook 400 (entry business), ProBook 600 (mainstream) and EliteBook 800 (premium flagship with the full Wolf Security and Bang & Olufsen sound). The 600 series sits in the middle: more than entry, without the premium price.
Within the HP ProBook 600 G5 line there are two size siblings: the HP ProBook 640 G5 (14″, the balanced standard) and the HP ProBook 650 G5 (15.6″, more screen area and usually a number pad). The HP ProBook 640 G5 is the more portable of the two.
By generation, the HP ProBook 640 G5 succeeds the HP ProBook 640 G4 and is succeeded by the HP ProBook 640 G7. The platform is Intel Whiskey Lake-U (U-series Core processors), a mature, widely deployed generation, which makes the model easy to support and source parts for as a refurbished laptop.
The HP ProBook 640 G5 is not ideal if… ▼
- You need a more powerful discrete graphics card for video editing, 3D work or CAD. The HP ProBook 640 G5 has integrated Intel UHD 620 or an optional Radeon 540X with 2 GB GDDR5; for those tasks look at the HP ZBook line.
- You treat minimum weight as a priority: the ~1.71 kg starting weight is more than the premium 14-inch machines. For ultraportability, look at the EliteBook 800 series or the HP Dragonfly.
- You want the full premium package: Bang & Olufsen audio, a world-facing microphone and the complete Wolf Security. That is HP EliteBook 840 G6 territory, not ProBook 600.
- You need a 2-in-1 with a tablet mode: the HP ProBook 640 G5 is a standard clamshell without 360-degree hinges. A touchscreen is available as an option, but it does not turn the model into a convertible.
- You want a 15-inch screen and a number pad: the direct alternative from the same generation is the HP ProBook 650 G5.
- You need a guaranteed specific configuration (IR camera, Sure View panel, FHD display, 4G LTE, a particular CPU/RAM/SSD): many of these are optional and vary unit to unit.
Choosing the right size and construction ▼
14-inch class (HP ProBook 640 G5): the balanced standard for mainstream business. Enough screen area for documents, spreadsheets and video calls, at a weight that stays comfortable to carry daily between desk and meeting room.
15.6-inch class (HP ProBook 650 G5): the same 600 series, but with a larger screen and usually a number pad. Better for work mainly at a desk, or for people who spend long hours in numeric spreadsheets.
Construction: the HP ProBook 640 G5 has an aluminium chassis, 20.9 mm thick without a touchscreen or 21.9 mm with one, in natural silver. The series passes MIL-STD-810G durability testing, built for daily corporate use and carrying over a span of years.
Display options: from HD TN to FHD IPS anti-glare, and on some units a high-brightness FHD IPS or a Sure View Gen3 privacy panel (nominally 1000 nits in the non-touch version). FHD IPS is the recommended choice for a full day of text work.
Alternative models ▼
Within HP:
HP ProBook 440 G6: the entry 14-inch HP ProBook from the 400 series, on the same Whiskey Lake-U base. More affordable, but it has no side docking connector and the build is more basic. The HP ProBook 640 G5 adds a side connector for the HP UltraSlim Docking Station, the IR camera option and a sturdier body.
HP ProBook 650 G5: the 15.6-inch sibling from the same 600 series. The same platform and features, but with a larger screen and usually a number pad. The choice here is about size, not class.
HP EliteBook 840 G5/G6: the step up, into the premium HP EliteBook 800 class. Bang & Olufsen sound, a world-facing microphone, a lighter chassis and the full Wolf Security. Trade-off: a higher refurbished price.
Cross-brand alternatives (14″, mainstream business class):
Dell Latitude 5400: Dell's direct mainstream rival, on the same Whiskey Lake-U platform. It leans on a larger 68 Wh battery for longer time unplugged. Trade-off against the HP ProBook 640 G5: HP answers with Thunderbolt 3 and upgradeable SO-DIMM memory.
Lenovo ThinkPad L490: the mainstream 14-inch Lenovo ThinkPad. It brings a fuller ThinkShield security package and the classic Lenovo ThinkPad keyboard with TrackPoint. The choice depends on whether the team values the keyboard or the connectivity more.
Note: do not compare the HP ProBook 640 G5 with the HP EliteBook x360 or HP Elite Dragonfly, as they are from a different, premium/ultra-premium class with a different target audience.
Refurbished by ITR Bulgaria: what value do you get? ▼
The HP ProBook 640 G5 is a model where refurbishment by ITR Bulgaria has clear logic. HP designed the series with a long corporate life cycle in mind: the internals are reachable with a few screws, the M.2 NVMe SSD and SO-DIMM modules are easy to replace, and the hardware documentation is thorough. That makes the technical audit and refurbishment straightforward and predictable.
On top of that comes the wide corporate footprint of the ProBook 600 series: spare parts, original chargers and docking stations stay available on the market even years after the model's launch. The upgradeable SO-DIMM memory means the machine can be expanded and serve even longer. After it has passed refurbishment, the model is prepared for repeated business use and comes with a real warranty and support from ITR Bulgaria.
Frequently asked questions ▼
Is the HP ProBook 640 G5 a good choice as a used laptop?
Yes, for a specific audience. ProBook 600 is a mainstream business series with a better build and connectivity than the entry class, at a more affordable price than the EliteBook.
