LG gram Book 15.6" 15U55T-H.AAB4U1 Black 2026

The LG gram Book 15U55T is an ultra-light 15.6-inch laptop with a touchscreen and solid productivity performance. Its integrated graphics are surprisingly capable, but the small battery and mediocre display hold it back. It's a niche pick for commuters who want a big screen without the weight.

For day-to-day stuff, this laptop is more than capable. The Core Ultra 7 255U handles browser tabs, Office apps, and video calls without breaking a sweat. In our benchmarks, the CPU sits right at the 70th percentile, which translates to a snappy experience for productivity but nothing that'll set records. The 16GB of dual-channel DDR5 RAM at 5600MHz is a smart move by LG, keeping things responsive even with a bunch of apps open.

The real surprise is the integrated Intel Arc GPU. Its 96th percentile ranking is genuinely impressive for integrated graphics, meaning you can actually do some light photo editing or play less demanding games without the whole thing grinding to a halt. But let's be clear, the gaming score of 19.9 out of 100 tells the real story. This is not a gaming laptop. The 512GB Gen4 NVMe SSD is perfectly fine, sitting right around average for storage speed, so boot times and app launches feel quick. The 51Wh battery is a weak spot, though. With a 15.6-inch screen to power, don't expect to leave the charger at home for a full workday.

Stacked against the competition, the LG gram Book carves out a specific niche. The Apple MacBook Pro M4 Pro absolutely demolishes it in performance, screen quality, and battery life, but it also costs significantly more. If you're in the Apple ecosystem and have the budget, it's no contest. The ASUS ROG Zephyrus G14 is a much better pick for anyone who wants to game or do creative work, packing a dedicated GPU and a gorgeous display into a still-portable 14-inch body.

On the Windows side, the MSI Prestige and HP OMEN Transcend 14 offer more balanced packages. The HP gives you a stunning OLED screen and better gaming chops, while the MSI focuses on a sleek, professional design with a sharper display. The Lenovo Legion Pro 7i is a full-on desktop replacement, way heavier but infinitely more powerful. The gram Book's only real win against these is weight. If you're comparing it to anything with a dedicated GPU, you're looking at the wrong laptop. This is for people who prioritize a light bag over raw power.

At $1000, the value proposition is a little tricky. You're paying a premium for that lightweight design and the big touchscreen. The specs are solid for productivity, but you can find laptops with similar internals and better build quality for less money if you're willing to sacrifice a bit of portability. The ASUS ROG Zephyrus G14, for example, is in a different league for performance, though it's a smaller screen. If the 15.6-inch form factor and sub-1.7kg weight are your absolute must-haves, the gram Book makes sense. Otherwise, you're paying a portability tax that might not be worth it for everyone.

The LG gram Book 15U55T is a bit of an odd duck in LG's lineup, and that's not necessarily a bad thing. It takes the ultra-light DNA of the flagship gram series and wraps it in a more affordable, touch-friendly 15.6-inch package. You're getting an Intel Core Ultra 7 255U processor, 16GB of DDR5 RAM, and a 512GB SSD, all running Windows 11 Home. It's clearly aimed at students, office workers, or anyone who wants a big screen for spreadsheets and Netflix without the back-breaking weight, coming in at just 1.65kg.

What's interesting here is the mix of specs. The integrated Intel Arc graphics actually score shockingly high in our database, landing in the 96th percentile for its class. That doesn't mean it's a gaming beast, far from it, but it does mean media playback and light creative work will feel snappier than you'd expect from integrated graphics. The CPU is solidly mid-pack at the 70th percentile, so everyday multitasking won't be a problem. Just don't expect it to chew through heavy video renders like a workstation.

At around $1000, the gram Book is competing with some seriously polished machines. The 1080p touchscreen is a nice addition for scrolling and tapping through apps, though the screen quality itself is just average. The real story here is portability and that big, usable display in a chassis that won't wreck your shoulder on a commute.

Skip the LG gram Book if you do any kind of gaming or GPU-heavy creative work. The gaming score is abysmal, and you'll be much happier with something like an ASUS ROG Zephyrus G14. Also look elsewhere if you need all-day battery life, the 51Wh cell just can't keep up with a screen this big. If build quality and reliability are top concerns, the low score here is a red flag, and a Lenovo ThinkPad or MacBook Air would be a safer bet.

The LG gram Book 15U55T is a laptop with a very clear mission: be as light as possible while giving you a big screen. It nails that. If you're a student lugging it across campus or a remote worker who moves from room to room, the weight alone might sell you. The performance is perfectly fine for office work, streaming, and browsing, and the touchscreen is a handy extra.

But you have to accept some serious trade-offs. The battery life is disappointing, the build quality doesn't inspire confidence given the low reliability score, and the display is nothing to write home about. Should you buy it? Only if portability is your absolute number one priority and you can't stand a smaller 14-inch screen. For everyone else, there are better all-around laptops at this price.
