日本HP EliteBook 640 G9 – Top 5 Pros and Cons
All of a sudden, there’s an EliteBook 600 series, which slides right between the ProBook 400 and the EliteBook 800 series. One theory going around the office is that HP is purposefully making some knockdown models for when corporations order notebooks in bulk, with standardized parts and security features. This way, they can definitely save a decent chunk of change, while HP makes a profit as well.
Let’s check out what the HP EliteBook 640 G9 has to offer, as we present you with LaptopMedia’s top 5 picks about it.
HP EliteBook 640 G9: Full Specs / In-depth Review
4 reasons to BUY the HP EliteBook 640 G9
1. Design and build quality
The laptop features an aluminum build for the lid and base, with a single plastic strip on the top portion of the lid for the antenna. Durability is good, as there’s the tiniest amount of flex from the chassis. The keyboard deck is solid as a rock, while the lid is a bit more flexible. For a 14-inch device, it’s lightweight, weighing only 1.37 kg and having a profile of 19.9 mm.
The lid opens up with one hand, showing us the base, with a long horizontal grill on top, and a keyboard, touchpad, and fingerprint reader below. The keyboard is fantastic, with spill resistance, long key travel, and clicky feedback. A Numpad is missing, but what can you do (unless you’re ASUS and have access to the NumberPad)? The touchpad isn’t as impressive, as the surface isn’t that smooth. At least the tracking is accurate.
2. Battery life
With a 51.3Wh battery pack, the EliteBook 640 G9 lasts for 13 hours and 20 minutes of web browsing and 10 hours and 18 minutes of video playback. Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with.
3. Display quality
The display on the EliteBook, while lacking the 16:10 aspect ratio of its more expensive relative, is still great, with an FHD resolution and an IPS panel. The display gets quite bright, reaching 429 nits, while the contrast ratio is high as well, at 1590:1. The panel shows 95% sRGB coverage.
The color coverage isn’t that bad with the stock settings (left), but with our Design and Gaming profile really lowers the dE value to a professional level (right). Here are the results of our test.

Office Work
Office Work moet vooral worden gebruikt door gebruikers die de meeste tijd besteden aan het bekijken van stukken tekst, tabellen of gewoon surfen. Dit profiel is gericht op het leveren van een betere helderheid en duidelijkheid door het behouden van een vlakke gammacurve (2.20), native kleurtemperatuur en perceptueel accurate kleuren.
Ontwerp en spel

Health-Guard
Health-Guard elimineert de schadelijke Pulse-Width Modulation (PWM) en vermindert het negatieve Blauwe Licht dat onze ogen en ons lichaam aantast. Omdat het op maat is gemaakt voor elk paneel, slaagt het erin de kleuren perceptueel nauwkeurig te houden. Health-Guard simuleert papier zodat de druk op de ogen sterk wordt verminderd.

4. Cooling
The laptop uses a simple cooling solution with one heat pipe and one fan.
Max CPU load
| Intel Core i5-1235U (15W TDP) | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| HP EliteBook 640 G9 | 3.27 GHz @ 2.77 GHz @ 90°C @ 45W | 2.53 GHz @ 2.32 GHz @ 90°C @ 30W | 2.32 GHz @ 2.17 GHz @ 74°C @ 24W |
| HP EliteBook 840 G9 | 3.09 GHz @ 2.75 GHz @ 83°C @ 46W | 2.73 GHz @ 2.46 GHz @ 89°C @ 37W | 1.58 GHz @ 1.67 GHz @ 61°C @ 17W |
As Michael Scott would say “How the turn tables”. All jokes aside, the Core i5-1235U does much better inside the more affordable 600-series EliteBook, running at higher wattage and clock speeds.
Comfort during full load
Despite the more performance, the laptop still runs cool and remains quiet, with a hotspot of just 37.5°C.
1 reason NOT to buy the HP EliteBook 640 G9
1. I/O
The laptop has decent I/O coverage but forgets the SD card reader, which can be important for a lot of people. If you can swallow that, the device is still full of other ports, with a total of three USB Type-A 3.2 (Gen. 1) ports, one Thunderbolt 4 port, an HDMI 2.0b port, an Ethernet port, and a 3.5 mm audio jack.
