Specifications

HP built the 840 G7 around a 10th Gen Comet Lake-U chip at a point when Intel was still leaning on a quad-core design rather than the hybrid architecture that would arrive a generation later. That makes it a straightforward, uniform four-core-eight-thread part, the kind of chip IT departments were rolling out by the thousand a few years back for exactly the workload it's still handling in refurbished form today. If you're new to buying this way, it's worth understanding what a refurbished laptop actually is and how grading works.

We spent time with an i5-10310U configuration, ran the full benchmark suite, and pulled together an honest read on where this machine still earns its keep and where the years show. Here's the breakdown.

Design & Build Quality

The HP EliteBook 840 G7 has an aluminum chassis with MIL-STD 810H durability testing, meaning it's rated to withstand drops, dust, humidity, and temperature extremes typical of daily business travel.

The 840 G7's shell keeps to HP's usual EliteBook restraint: a muted silver finish that looks the same whether it's sitting on a CEO's desk or the twentieth cubicle down the row. There's very little flex through the keyboard deck, and the hinge holds its position without drooping, even one-handed.

At roughly 1.36 kg, it's easy to carry through a full day without noticing the extra weight, and the 14-inch footprint keeps it a size smaller than most 15.6-inch business laptops without shrinking the typing experience down with it.

The Display

The HP EliteBook 840 G7 uses a 14-inch Full HD (1920 x 1080) anti-glare IPS panel, rated at approximately 250 nits of brightness.

Text stays sharp, colours stay consistent from most viewing angles, and the anti-glare coating keeps window reflections from becoming a fight during a video call. It won't wow anyone doing photo work, but that was never the assignment. For a screen that's mostly going to show email, spreadsheets, and a video call window for eight hours a day, that's a fair trade.

Keyboard & Touchpad

Keyboard

The backlit keyboard carries the firm, well-defined key travel HP's business line is known for, with a solid bottom-out that holds up to long typing sessions without feeling mushy. Key spacing is generous for a 14-inch chassis, and there's no awkward compression around the arrow keys the way some smaller laptops manage.

Touchpad

The touchpad is smooth, accurate, and supports Windows Precision gestures cleanly, so three- and four-finger swipes register on the first try rather than needing a second attempt. A fingerprint reader sits below the keyboard, a small convenience that matters on a machine that gets picked up and unlocked all day long.

Performance & Benchmarks

Specs on a spec sheet only tell part of the story, so we ran the review unit through a full round of benchmarks to see how it actually behaves once it's doing real work.

Benchmark Scores at a Glance

CPU Details (CPU-Z)

CPU-Z confirms the chip inside: an Intel Core i5-10310U, codenamed Comet Lake-U/Y, built on Intel's 14nm process in a Socket 1528 FCBGA package. It's a conventional 4-core, 8-thread design with a 15.0W max TDP and a Core VID of 0.900V, base clocked at 1.70GHz with a multiplier that ranges from x7.0 up to x44.0, meaning it can turbo as high as 4.4GHz under the right conditions. It's backed by 6MB of L3 cache and supports the full run of AVX2, AES, and FMA3 instruction sets. There's no hybrid core split here; this is Intel's older, simpler approach to squeezing threaded performance out of a thin-and-light chassis, one generation before Alder Lake changed the formula.

CPU Performance (Cinebench R23)

It's a competent showing for a 15W part from 2020, just not a fast one by current standards.

CPU Benchmark (Geekbench 5)

In Geekbench 5, the HP EliteBook 840 G7 posts a single-core score of 1355 and a multi-core score of 3036.

For a 15W chip pushing four years old, it's still enough headroom for spreadsheets, a dozen browser tabs, and a video call running at the same time. Just don't expect it to fly through anything heavier.

Graphics Performance (3DMark)

It's fine for driving an external monitor, handling video calls, and playing back everyday video, but 3D workloads of any kind, games included, are off the table. This is graphics silicon built to stay out of the way, not to be noticed.

Storage Performance (CrystalDiskMark)

The 256GB NVMe SSD hits 553.13 MB/s sequential read and 478.30 MB/s sequential write, which is well ahead of a SATA SSD but behind current Gen4 NVMe drives.

It's the component doing the most to keep the system feeling current despite the older CPU.

Overall System Performance (PCMark 10)

The HP EliteBook 840 G7 scores 3574 overall in PCMark 10, behind 81% of all submitted results and below the "Office laptop (2023)" average of 5848.

That's a meaningful gap, and it tracks with a quad-core, 15W chip from 2020 being measured against a benchmark pool that's increasingly full of newer hybrid-core machines. The Essentials and Productivity scores are the ones that matter most day to day, and they still land in a comfortable zone for web browsing, spreadsheets, and writing.

Everyday App Checks

• Microsoft Office: Opens and saves typical office files without noticeable delay, helped by the NVMe drive.
• Google Chrome: Handles 10-15 tabs comfortably; push past that during a video call and the quad-core CPU starts to show it.
• Video Conferencing: Smooth for 1080p calls on their own, though CPU load climbs quickly once other apps are running alongside a call.

Hardware Details

The EliteBook 840 G7 runs on a 10th Gen Intel Core i5-10310U, part of Intel's Comet Lake-U family and built on a 14nm process, confirmed directly from our test unit via CPU-Z. It's a conventional four-core, eight-thread design, the same core architecture Intel had been refining for several generations before the hybrid Alder Lake chips arrived.

It carries a 15W max TDP, so HP has tuned it for a sensible balance of battery life and responsiveness rather than sustained peak output. Paired with 6MB of L3 cache and Intel UHD Graphics on the same die, it's a chip built for office computing and video calls, not gaming or content creation, and every benchmark above backs that positioning up.

Battery Life

The HP EliteBook 840 G7 typically ships with a 3-cell, roughly 53Wh battery, delivering an estimated 7 to 9 hours of real-world mixed use.

As with the rest of the EliteBook range, HP hasn't made the battery a nightmare to service. Getting to it involves the base panel and a standard set of screws, so a worn cell further down the line is a routine swap rather than a repair-shop trip.

Ports and Connectivity

HP spreads the port selection across both sides of the chassis, keeping cable clutter away from either hand.

Two Thunderbolt-capable USB-C ports mean a single dock can charge the laptop, drive an external display, and move data at the same time, which covers most modern office docking setups without extra dongles. The separate barrel power connector is a useful fallback, letting you charge from the original HP adapter while both USB-C ports stay free. Wi-Fi 6 support adds a faster, less congested wireless connection on networks that support it.

HP EliteBook 840 G7 vs. a Current Office Laptop

Here's how the 10th Gen HP EliteBook 840 G7 stacks up against a typical current-generation (2023-2026) office laptop, based on PCMark 10 data. For a like-for-like refurbished comparison, our Dell Latitude 5400 review covers a similarly priced 8th Gen Core i7 machine.
