ASUS Chromebook 14 CX1405CTA Laptop | 14.0" Full HD Screen | Intel Celeron N50 Processor | 4GB RAM | 64GB eMMC | Google Chrome OS

Most laptop adverts show someone working in a sun-drenched loft, battery at 80%, fan silent, coffee still hot. What they don't show is the scramble for a plug socket two hours in, the fan kicking off like a hairdryer during a video call, or the screen that's basically invisible the moment you sit near a window. The real test of any laptop is whether it holds up across an ordinary day, not a staged photoshoot. That's what I've been putting the ASUS Chromebook 14 CX1405CTA Laptop to over the past month.

I picked this up as part of my ongoing look at budget Chromebooks for people who just need something that works. Students, parents buying a second machine for the kids, small business owners who live in Google Workspace, retired folk who want email and YouTube without the faff of Windows updates. The ASUS Chromebook 14 CX1405CTA sits in that bracket, priced affordably and packing a 14-inch Full HD screen, Intel Celeron N5100 processor, 4GB of RAM, and 64GB of eMMC storage running Chrome OS. On paper, it's a sensible package. But does it actually deliver?

I've used this machine at my desk, on trains, in a couple of coffee shops, and on the sofa. I've thrown Google Docs, Sheets, YouTube, Google Meet calls, and a fair amount of tab-heavy browsing at it. Here's what I found.

The 4GB of RAM is the spec that'll raise eyebrows, and honestly, it should. In 2026, 4GB is tight. On Windows, it'd be a dealbreaker. On Chrome OS, it's manageable but you will notice it if you're someone who keeps 15 tabs open while streaming music and running a Meet call. I hit the ceiling a few times during testing, and Chrome OS does its tab-discarding thing where it reloads tabs you haven't looked at in a while. It's not catastrophic, but it's there. If you're disciplined about tabs, you'll be fine. If you're not, you'll find it mildly irritating.

Storage is 64GB of eMMC. That sounds small, but Chrome OS itself takes up very little space, and most of your stuff lives in Google Drive anyway. The eMMC is slower than an SSD, which you notice occasionally when booting apps, but Chrome OS boots in seconds regardless. There's no option to expand storage internally, so if you need more local space, you're looking at a USB drive or a microSD card. The machine does have a microSD slot, which helps. The integrated Intel UHD Graphics handles video playback and light image work without complaint. Don't expect more from it than that.

In real use, the machine handles Google Docs and Sheets without any noticeable lag. I typed long documents, ran formulas across spreadsheets, and had Google Meet running in a separate window, all at the same time. It coped. Where things got sticky was when I pushed it harder: eight or more tabs open, a YouTube video playing, and a Google Slides presentation with embedded images. The machine slowed noticeably, tab reloading kicked in, and scrolling became slightly choppy. It recovered once I closed a few things, but it's a reminder that 4GB of RAM is the real bottleneck here, not the processor.

Android apps from the Play Store work, but with caveats. Simple apps like Spotify, Netflix, and basic productivity tools run fine. Heavier apps are hit and miss. I tried a couple of Android games and they ran, but not smoothly. That's not really what this machine is for, and I wouldn't hold it against it. Chrome OS is the star here, and within Chrome OS, the performance is genuinely good for the price. Linux app support (via Crostini) is available, but I wouldn't recommend it on 4GB of RAM unless you're very patient.

Boot time is quick, around eight seconds from cold to the login screen. Waking from sleep is near-instant. These are things that matter day to day, and Chrome OS handles them well regardless of the hardware underneath. The overall experience is snappy for everyday tasks, and that's what most buyers in this price bracket need.

Brightness is rated at 250 nits, which is adequate for indoor use but starts to struggle in direct sunlight. In a coffee shop with overhead lighting, it was fine. Outside on a bench, I had to angle the screen and crank brightness to maximum, and even then it wasn't ideal. If you're planning to work outdoors regularly, this is worth knowing. For the vast majority of use cases, though, 250 nits is enough. Most people use laptops indoors.

Colour accuracy is decent but not calibrated for creative work. The panel covers around 60% of the sRGB colour space, which is typical for budget IPS displays. If you're editing photos or doing any kind of colour-sensitive design work, you'll want something better. For everything else, watching videos, reading documents, browsing, the colours look natural and pleasant. Viewing angles are good, as you'd expect from IPS. You can tilt the screen quite far without the image washing out, which is handy when someone's trying to look at your screen from the side.

One thing I appreciated: the anti-glare coating doesn't add the grainy, sparkly texture that some cheaper panels have. It's a clean matte finish that reduces reflections without degrading image quality. Small detail, but it makes a difference over a long session.

For light browsing and document work with the screen at around 70% brightness, I consistently got eight to nine hours. That's a full working day without needing a charger. Streaming YouTube at the same brightness dropped that to around seven hours. Running a Google Meet call with camera on, screen at full brightness, brought it down to about six hours. Still respectable. The Celeron N5100's efficiency really shows here. It's not a fast chip, but it sips power, and on Chrome OS that translates to genuinely good battery life.

The charger is a 45W USB-C unit. Charging from flat to full takes around two hours, which is fine. You can also charge via either of the USB-C ports, which means you're not locked to one side of the machine. That's a practical detail that matters when you're at a desk with cables running in a specific direction. I charged it from a 65W USB-C power bank during one train journey and it worked without complaint. USB-C charging compatibility is something I always check, and this one passes.

One thing to flag: the battery is 42Wh, which is on the smaller side. The good battery life comes from efficiency, not capacity. If you're doing something unusually demanding, like running Linux apps or pushing the processor hard, you'll see the battery drain faster than the headline figure suggests. But for the typical Chromebook use case, the battery life is one of the best things about this machine.

Thickness is just under 20mm, which is slim without being fragile. It slides into a laptop sleeve easily. The charger is a compact USB-C brick, not one of those enormous barrel-plug adapters that adds bulk to your bag. The whole travel setup, laptop plus charger plus cable, is genuinely light. I've tested machines in this category that come with chargers heavier than the laptop itself. This isn't one of them.

Who is this for, in terms of portability? Students carrying it between lectures, people who commute and want something to work on during the journey, parents who need a portable machine for the kids to use around the house. It's not a machine you'd buy for its portability alone, but it doesn't get in the way of being portable either. That's the right balance at this price point.

There's no keyboard backlight, which is a shame. It's a common omission at this price, but it's still annoying if you work in low light. The key legends are clear in good lighting, but in a dim room you're relying on muscle memory. Not a dealbreaker, but worth knowing. The keyboard deck has a slight flex when you press firmly in the centre, which is typical of plastic-chassis laptops. It doesn't affect typing, but it's there.

The trackpad is a decent size and uses a smooth plastic surface that feels comfortable under the fingertips. Tracking accuracy is good, and Chrome OS's gesture support works well: two-finger scrolling, three-finger tab switching, pinch to zoom. The click mechanism is a bit on the firm side, which some people prefer and others find tiring. I'm somewhere in the middle. It's not a glass trackpad and it doesn't pretend to be, but it does the job reliably. No phantom clicks, no missed gestures, no drifting cursor. The basics, done properly.

Under sustained load, things warm up slightly but not alarmingly. Running a Google Meet call while streaming video and keeping multiple tabs open, the underside reached around 35 to 37 degrees Celsius in my testing. The palm rest stayed cooler than that. The fan did kick in occasionally under these conditions, but only briefly and at a low speed. Surface temperatures never reached the point where I'd describe the machine as hot. Warm, at most.

Throttling is minimal in normal use. The N5100 can sustain its burst clock for short periods and then settles back to a comfortable sustained speed without the dramatic performance drops you sometimes see on thin-and-light Windows machines with more powerful chips. The trade-off is that the ceiling is lower, but the floor is also higher. Consistent, predictable performance is actually more useful in daily life than occasional bursts of speed followed by throttling.

For lap use, this is one of the better machines I've tested at this price. The vents are positioned at the rear, so hot air doesn't blow onto your hands or legs. Sensible design that makes a real difference in comfort.

When the fan does spin up, it's quiet. I measured it at around 32 to 34 dB in a quiet room, which is barely above ambient noise. The character of the fan is a low, steady whoosh rather than a high-pitched whine. It's not the kind of sound that draws attention in a meeting or a coffee shop. I had it on a video call and the person on the other end couldn't hear it at all. That matters.

Even under sustained load, the fan never got loud enough to be genuinely annoying. It's one of the quietest laptops I've tested this year, and that's partly the chip and partly ASUS's thermal design. If acoustic performance is a priority for you, this machine delivers. It's not something you'd normally expect to highlight in a budget laptop review, but it's a real differentiator here.

Wi-Fi 6 (802.11ax) is a genuine surprise at this price point. Most budget Chromebooks ship with Wi-Fi 5, so getting Wi-Fi 6 here is a meaningful upgrade. In practice, it means faster speeds on compatible routers and better performance in congested environments (busy offices, flats with lots of neighbouring networks). Bluetooth 5.0 is present and worked reliably with my headphones and mouse throughout testing.

The placement of ports is sensible. Having the USB-C ports on the left means you can charge from either side depending on where your socket is, and the USB-A on the right is handy for a mouse without the cable crossing your workspace. The microSD slot is flush-fitting, which means a card stays in without sticking out awkwardly. Small things, but they add up to a machine that's been thought about rather than just assembled.

• 2x USB-C 3.2 Gen 1 (left side, both with PD charging and DisplayPort output)
• 1x USB-A 3.2 (right side)
• 1x microSD card slot (right side)
• 1x 3.5mm headphone/microphone combo jack (left side)
• Wi-Fi 6 (802.11ax), 2x2 MIMO
• Bluetooth 5.0

The microphone is a dual-array setup and it does a decent job of picking up voice while reducing background noise. On calls, I sounded clear to the people I was speaking to, and the mic didn't pick up the keyboard noise as badly as some laptops I've tested. There's no physical privacy shutter on the webcam, which is a minor gripe. A lot of Chromebooks at this price include one, and it's a useful feature.

The speakers are bottom-firing and they're fine for casual use. Volume is adequate for a quiet room, and the sound is clear enough for YouTube and video calls. Don't expect bass. There isn't any. But for spoken word content and background music at low volume, they do the job. Plug in headphones or a Bluetooth speaker if audio quality matters to you. The headphone jack works well, no interference or hiss that I noticed.

Lid flex is present but not excessive. You can flex the lid with one hand, but it doesn't feel like it's about to crack. The keyboard deck is more solid, with only minor flex when you press hard in the centre. The hinge is firm enough to hold the screen at any angle without wobbling, and it opens to around 135 degrees, which is enough for most use cases. It won't lie flat, so if you need that for a specific workflow, it's worth knowing. One-handed opening is possible but requires a bit of effort as the base lifts slightly.

For a budget machine, the build inspires reasonable confidence. I wouldn't throw it in a bag without a sleeve, but I wouldn't be precious about it either. It's the kind of laptop you can hand to a teenager without too much anxiety. The port openings are clean, the keys don't rattle, and the trackpad doesn't creak. These are the details that distinguish a well-made budget laptop from a poorly made one, and the CX1405CTA is on the right side of that line.

ASUS has put this through military-grade durability testing (MIL-STD-810H), which covers things like temperature extremes, vibration, and humidity. That's a meaningful certification, not just a marketing badge. It doesn't mean you should drop it, but it does suggest the machine is built to handle the knocks of daily life better than a machine without that testing behind it. You can find more detail on ASUS's approach to this on the official ASUS UK product page.

The ASUS wins on display size and Wi-Fi standard. A 14-inch Full HD screen with Wi-Fi 6 at this price is genuinely competitive. The Acer 314 often ships with Wi-Fi 5 and a lower-resolution display depending on the configuration. The Lenovo Flex 3 has the touchscreen and 2-in-1 flexibility, which is a real advantage if you want to use it in tablet mode or with a stylus. But the smaller 11-inch screen is a meaningful compromise for anyone doing real work.

Where the ASUS falls short is RAM. Some configurations of the Acer 314 ship with 8GB, which makes a noticeable difference in Chrome OS. If you can find an 8GB Acer 314 at a similar price, it's worth considering. But if the choice is between a 4GB Acer and a 4GB ASUS, the ASUS wins on screen size and Wi-Fi. The Lenovo Flex 3 is the right choice if 2-in-1 functionality matters more than screen size. For straightforward laptop use, the ASUS holds its own.

One thing that genuinely sets the CX1405CTA apart is the combination of Wi-Fi 6 and dual USB-C with DisplayPort. At this price, that's not a given. It's the kind of spec that suggests ASUS thought about what buyers actually need rather than just hitting a price point with the cheapest possible components.

The 4GB of RAM is the honest caveat. It's enough for disciplined users, but if you're someone who keeps dozens of tabs open or wants to run Android apps alongside your browser work, you'll hit the ceiling. The 64GB of storage is fine given how Chrome OS works, but it's worth being aware of. There's no keyboard backlight, no touchscreen, and the webcam is only 720p. These are all reasonable compromises at this price, but they're worth knowing about before you buy.

For students, parents buying a secondary machine, or anyone who wants a reliable, quiet, light laptop for Google Workspace and web browsing, this is a solid choice. It earns a 7 out of 10 in the budget tier. It's not exciting, but it's honest, capable, and well-priced. Sometimes that's exactly what you need. The No rating rating from 0 buyers on Amazon lines up with my experience: this is a machine that does what it says, reliably, without drama.
