The Hãng Asus ExpertBook B9 is being marketed as the world’s lighchạy thử 14-inch business laptop.

The ExpertBook weighs just 888g, so this machine feels almost lighter than air, but there are compromises elsewhere, including middling components & display technology. With this in mind we’ve sầu thoroughly tested the device to find out how does it staông xã up against the competition. Here’s what we found out.

Price & availability

The mã sản phẩm I reviewed uses the part code B9400CEA, và it costs £1659 or $1699. It’s available in Europe, too, although it costs a fairly hefty €2736 on some sites. It’s also not listed on the Asus stores in various European countries, so it looks lượt thích continental availability is patchy right now.

At the time of writing, it’s only available with a Chip Core i7 processor. It’s listed on Asus’ trang web with a Vi xử lý Core i5 processor, too, so hopefully that option becomes available khổng lồ reduce the cost.

Design and keyboard

One of the thinnest and lightest laptops in the worldImpressive sầu build unique và features considering the sizeKeyboard is good, but rivals are better – & better-looking, too

The B9’s minuscule weight pairs with a body toàn thân that’s just 320milimet wide và 14.9mm thick, so it’s one of the most compact machines on the market.

Such a svelte body always makes me wonder about build chất lượng, & there is a certain amount of give sầu in the B9 – the screen is more flexible than most, & there’s noticeable movement in the metal around the keyboard and the base.

That’s by kiến thiết though: the Asus uses multiple layers of magnesium-lithium alloy rather than a single blochồng of metal, and it’s had MIL-STD-810G testing khổng lồ ensure that it can withst& pressure, shocks, drops, vibrations, altitudes, & extreme temperatures. The hinge, ports và keyboard have sầu also undergone similar tests.


So, while the Asus’ toàn thân does flex, it’s designed to lớn take the bumps and keep working, so I’ve sầu got no qualms about tossing this laptop in a bag.

This approach marks the Asus out from its biggest rivals. The Dell XPS 13 & Apple MacBook Air don’t have sầu MIL-STD-810G certification, but they’re made from single blocks of metal and so feel initially more robust. The machines have all undoubtedly undergone similar testing. I have sầu confidence that the Hãng Asus is sturdy enough to lớn survive sầu daily life – it’s a different approach to rivals.

The alternative approach from Asus also means that its ExpertBook undercuts its rivals in portability. The Dell weighs 1.2kg and is 14.8milimet thiông chồng, while the lathử nghiệm MacBook is a 1.29kg notebook with a 16mm toàn thân.


Hãng Asus has done an admirable job of cramming features inside this tiny machine. On the right-hvà edge it’s got a full-size USB 3.2 Gen 2 port, a headphone jachồng, & a Kensington lochồng slot, & on the left, you’ll find two Thunderbolt 4 ports that support DisplayPort & power delivery alongside an HDMI output. Interestingly, the Hãng Asus also includes micro-HDXiaoMI, which works with an included adapter to lớn provide Gigabit Ethernet without occupying a USB socket. The only notable omission is a thẻ reader, which will be a hassle for photographers looking khổng lồ quickly transfer files between it and their camera.

Above the display, you’ll find a webcam with a privacy shutter and Windows Hello tư vấn, and below the keyboard is a fingerprint reader. On the inside, the Asus has dual-band Wi-Fi 6 and Bluetooth không dây 5.1 & a TPM 2.0 chip for security.

Neither rival can compete here. The Dell has the same internal connectivity, & it includes two Thunderbolt 4 ports alongside a microSD slot, but it has a weaker webcam, no full-kích thước USB connection, & no HDMI. The MacBook Air has Thunderbolt 4 ports, but that’s it.


The B9’s keyboard has a spill-resistant design, & it has satisfactory performance – the buttons are fast and consistent, & they’ve sầu got reasonable travel, but they proved a little too spongy for my liking during testing.

I still prefer the typing gear on the Dell and Apple machines, because both of those keyboards are crisper và quicker. The Hãng Asus will easily handle hours of typing, but the Dell & Apple machines feel cleaner and more satisfying to lớn type on.

The trackpad is huge and responsive sầu, so no complaints there. It also has a numberpad overlay, which is a helpful addition for people who spover lots of time in Excel.

The business-focussed Asus does fall behind in other areas. Its matte blachồng metal looks decent, but both rivals are more stylish. The ErgoLift hinge digs into your thighs if you sit down, and the inclusion of the power button on the keyboard is a perennial irritation.

The competition arguably offers better value, too. An equivalent Dell XPS 13 costs £1599 / $1549 / €1699, & a MacBook Air is £1649 / $1649 / $1699, & there are more customisation options, so you get chances khổng lồ reduce the price that just don’t exist with the ExpertBook.


The 1080p panel offers solid unique & accuracy for everyday workloadsRivals go further here, with brighter và sharper screens on offerThe speakers are disappointing

The display is a non-touch, 1080p IPS with an anti-glare coating, which is an entirely sensible business specification. The lid folds flat for easier collaboration, and the drop-hinge means the bottom bezel vanishes entirely, which looks sleek.

For everyday work, photo-editing, and truyền thông media, the Asus’ display is top-notch. The Dell & Apple machines go further, though: Apple’s Retina display is brighter, sharper và adheres lớn the DCI-P3 gamut. The XPS’ default screen is a 16:10 model with a higher resolution, & it’s available with 4K và touch options. màu sắc gamuts are ranges of color used by professionals to lớn gauge accuracy.


I used a colorimeter to find more specific results for the Hãng Asus ExpertBook B9’s display khổng lồ baông xã up my own judgement.

The brightness cấp độ of 375 nits is fine for indoor và outdoor use, và the 0.27 nit black point is reasonable. The contrast ratio of 1388:1 is a great result for an IPS panel and delivers superb vibrancy and depth.

Meanwhile, the speakers are mediocre: tinny and without bass, & without much mid-range clarity. They’re only suitable for casual media duties.


Intel’s chips are decent mainstream options, but Apple và AMD are both quickerSome CPU throttling means you won’t get the most out of this chipQuiet but noticeable tín đồ noise is evident in tougher tasks

The Asus relies on the familiar Chip Core i7-1165G7. It’s one of Intel’s most reliable máy vi tính chips, with four cores and a potential top speed of 4.7GHz. It’s paired with 16GB of memory và a 1TB SSD.

For web-browsing, Office software, photo-editing và mainstream applications, this specification is acceptable. The integrated Hãng Intel Iris Xe graphics chip will also run low-kết thúc games, lượt thích esports titles and casual games. The SSD delivered read and write speeds of 3,545MB/s & 2,882MB/s, which are solid results that keep the machine responsive sầu. These days, though, Intel’s silibé is falling behind, and benchmarks show the gulf in performance.

In Geekbench 5’s single- & multi-core tests the Asus scored 1503 và 4983. Those aren’t bad, but the new M1 chip inside the MacBook Air hit 1731 & 7308 in the same tests. The Dell uses the same CPU, but that laptop scored 5687 in the multi-core benchmark. If you’re willing khổng lồ look beyond ultra-portables, AMD’s máy vi tính chips are even faster in multi-core scenargame ios.

The minor reduction in the Asus’ performance is explained by examining CPU speeds: during more arduous single-core tasks the CPU hit its advertised pace, but in multi-core testing the chip throttled to lớn 3GHz rather than its theoretical all-core turbo clochồng of 4.1GHz. It’s not a big issue, but it does explain the discrepancy.


The Hãng Asus also makes a little high-pitched fan noise during tougher work tasks. The fans are quiet và won’t ruin your workflow, but this machine is not silent, unlike the MacBook.


There’s easily enough power here to handle a full day of workIf you’re careful, the Hãng Asus will last ‘til bedtimeIts rivals are no better – & worse in some cases

In a PCMark test that simulates a typical office workload with the display at half brightness the Asus lasted for 14hrs 4mins, và with the screen at peak brightness that dropped to 12hrs 10mins. In a đoạn Clip playbaông chồng benchmark the B9 lasted 15hrs 7mins.

Those are superb results – you’ll easily manage a full day of work, & it’ll handle some time on the sofa in the evening, too. These results compare well to lớn rivals: the MacBook Air offered broadly similar longevity, & the Dell only matched these figures in its 1080p configuration.


There are caveats, though. If you want to lớn push the B9’s components, then expect the battery khổng lồ last for between three & four hours. Also bear in mind that in some territories the Hãng Asus is being produced with a 33Wh battery with half the capacity of the mã sản phẩm reviewed here, và that will impact battery life significantly.


The Hãng Asus ExpertBook B9 is one of the slimmest and lighdemo laptops in the world, và it still includes tried-and-tested build quality, so it’s ikhuyễn mãi giảm giá if you want a svelte máy vi tính for life on the road.

It’s packed with business features, và it has a decent screen, comfortable keyboard, and impressive sầu battery life. Conversely, rivals offer more speed, better screens, and snappier keyboards, often at lower prices & inside better-looking designs.
