Snapshot
The 30-Second Version
The LG gram Book 15U55T is an ultra-light 15.6-inch laptop that's perfect for commuters and students who prioritize portability. It handles everyday work smoothly but falls flat on gaming and has worrying reliability scores. The small battery and average display are trade-offs you make for that impressively low weight.
Pros & Cons
Pros
- Incredibly light for a 15.6-inch laptop 96th
- Solid everyday performance from the Core Ultra 7 66th
- Good port selection with full-size HDMI
- Touchscreen is responsive and accurate
- Integrated GPU punches above its weight for an iGPU
Cons
- Reliability scores are among the worst we've seen
- Battery life is limited by the small 51Wh cell
- Display is just average, no high refresh rate
- Gaming performance is practically nonexistent
- Storage is only 512GB with no easy upgrade path
What owners think
The proof
Performance
The Core Ultra 7 255U is a 12-core chip that handles office work, streaming, and light photo editing without breaking a sweat. In our database, it sits around the 60th percentile for laptop CPUs. That's not going to set any records, but it's more than enough for the kind of work this machine is built for. You can run dozens of browser tabs, Slack, Spotify, and a few Excel sheets simultaneously and the fan barely spins up. The 16GB of RAM helps a lot here, keeping things smooth even when you're pushing the system.
Where things get interesting is the GPU. The integrated Intel Arc graphics score in the 96th percentile, which sounds incredible until you realize that's compared to all integrated GPUs, not discrete ones. In practice, it means you can do some light creative work or play older titles at low settings, but this is absolutely not a gaming laptop. Our gaming score for this config is a brutal 20.4 out of 100. If you try to run Cyberpunk or even a recent Call of Duty, you're going to have a bad time. For media consumption and basic photo edits, though, the GPU handles itself fine.

vs Competition
Stacked against the Apple MacBook Pro M5 Pro, the LG looks like it's playing a different sport. The MacBook destroys it in performance, display quality, and battery life, but it also costs significantly more. The ASUS ROG Zephyrus G14 is another beast entirely, a compact gaming powerhouse that makes the gram Book's gaming score look like a typo. If you want to play games, just buy the Zephyrus and don't look back.
A more realistic competitor is the MSI Prestige 13 EVO. It's even lighter than the LG and offers a sharper display, though you sacrifice screen size. The Lenovo Legion Pro 7i is in a different weight class entirely but shows what you can get for a bit more money if you don't mind lugging around a heavier machine. The LG's main advantage over all of these is that specific combination of a 15.6-inch screen and sub-1.7kg weight. Nobody else really nails that niche at this price.

Price
Value & Pricing
Without a firm price from LG, we're looking at retailer listings between $870 and $949. At that price, the gram Book is competing directly with machines like the Acer Swift Go and some configurations of the ASUS Zenbook. You're paying a premium for the weight, plain and simple. If portability is your top priority and you need a 15-inch screen, the value proposition makes sense. But if you can live with a slightly heavier laptop, you'll get better screens, bigger batteries, and more storage for the same money elsewhere. The HP OmniBook X Flip, for example, gives you a much nicer display and better build quality in a similar price range.

Overview
The LG gram Book 15U55T is one of those laptops that makes you do a double take. You see the 15.6-inch touchscreen and the Intel Core Ultra 7 chip, and you assume it's a standard mid-range machine. Then you pick it up. At 1.65kg, it's shockingly light for a 15-inch laptop. If you're a student or a commuter who wants a big screen without the back pain, this thing immediately gets your attention. Prices hover between $870 and $949, which puts it in a crowded field of Windows laptops, but the gram Book's weight is its main party trick.
Under the hood, you get 16GB of DDR5 RAM and a 512GB NVMe SSD. That's a solid combo for everyday multitasking, though the storage is about average for this price bracket. The integrated Intel Arc graphics are surprisingly capable for an iGPU, landing in the 96th percentile among all laptops we've tested. But don't let that ranking fool you into thinking this is a gaming rig. It's not. The display is a basic 1920x1080 IPS panel, and the 51Wh battery is smaller than we'd like to see in a portable machine.
LG markets this as a thin and light laptop, and it delivers on that promise. The port selection is decent with two USB-C, two USB-A, and a full-size HDMI that can push 4K at 60Hz. Wi-Fi 6 keeps you current on wireless. But there are some cracks in the foundation, especially around reliability, which we'll get into. For now, just know this is a laptop that prioritizes portability above almost everything else.
Common Questions
Q: Is the LG gram Book good for gaming?
No, the LG gram Book is not good for gaming. It scores a 20.4 out of 100 in our gaming benchmarks, so it can only handle very old or simple titles at low settings.
Q: How much does the LG gram Book 15U55T weigh?
The LG gram Book 15U55T weighs 1.65kg, which is exceptionally light for a 15.6-inch laptop. It's one of the lightest options available with a screen this size.
Q: Does the LG gram Book have a touchscreen?
Yes, the 15.6-inch 1920x1080 IPS display on the LG gram Book 15U55T supports touch input. It's responsive and works well with Windows 11 gestures.
Q: What is the battery life like on the LG gram Book?
The LG gram Book has a 51Wh battery, which is on the smaller side for a 15-inch laptop. You should expect to get through most of a workday with light use, but heavy multitasking will drain it faster.
Who Should Skip This
Skip the LG gram Book if you play games at all, even casually. The integrated graphics just can't keep up with modern titles. Also look elsewhere if you need all-day battery life away from an outlet, the 51Wh cell is too small for that. Creative professionals who need a color-accurate, high-resolution display will find the 1080p IPS panel limiting. For a similar price, the ASUS Zenbook 14 offers a much better OLED screen and longer battery life, though it's a smaller display. If reliability is a top concern, the concerning 10th percentile score here should push you toward a Lenovo ThinkPad or Dell XPS instead.
Verdict
The LG gram Book 15U55T is a laptop with a very clear identity. It's for people who want a big screen that feels like it's barely there. If you're a writer, a student, or anyone who carries their laptop around all day and primarily works in a browser, this machine is a joy to use. The keyboard is comfortable, the touchscreen is a nice bonus, and the performance is perfectly adequate for productivity tasks.
But you need to go in with your eyes open. The reliability data we have is concerning, sitting in the 10th percentile. That means we've seen higher than average failure rates or build quality complaints for similar LG gram models. The battery is small, so you'll be hunting for outlets more often than you'd like. And if you have any gaming ambitions at all, even casual ones, this is not your laptop. Buy it for the weight, but understand what you're trading away.
