ASUS Vivobook 15 (X1504VA) specs, features and buying guide
The ASUS Vivobook 15 X1504VA is an everyday 15.6-inch laptop: a full-HD anti-glare screen, a 13th Gen Intel Core U-series processor, 16 GB of DDR4 memory and a 512 GB or 1 TB SSD in a 1.70 kg chassis. It is built for documents, browsing, video calls and coursework rather than gaming or colour-accurate work.
The screen measures 15.6 inches diagonally at 1920 x 1080, with an anti-glare finish, 250 nits of brightness, a 60 Hz refresh rate and 45% NTSC colour coverage. ASUS quotes an 84% screen-to-body ratio, so the bezels are slim for an everyday laptop, and the chassis is 1.79 cm thick and 1.70 kg.
Inside, ASUS lists three 13th Gen Intel Core U-series processors for this model: the Core i7-1355U, the Core i5-1334U and the Core i3-1315U. Memory is 16 GB of DDR4 in a single SO-DIMM slot with a 16 GB ceiling, and storage is a 512 GB or 1 TB M.2 NVMe SSD on PCIe 3.0. Graphics are Intel UHD, with Iris Xe only on the Core i5 and i7 builds that run dual-channel memory, which ASUS states on its own specification page.
Two details decide whether a particular listing suits you. ASUS sells several X1504VA configurations, so the processor, SSD size, keyboard backlight and even whether a power adapter is included vary by model and by region — ASUS says adapter inclusion depends on country, region and model. And the USB-C port on this build is data only: ASUS lists no DisplayPort output and no charging over USB-C.
What to check before you buy the Vivobook 15 (X1504VA)
Read the model string, not just the product name. X1504VA covers Core i3, i5 and i7 builds with different SSDs, and the specification table above reflects the range ASUS publishes rather than one fixed configuration. Match the processor and SSD in the listing against what you actually need, because the price difference between those builds is real and the badge on the lid is identical.
Then decide on memory. There is one DDR4 SO-DIMM slot and a 16 GB maximum, so a 16 GB machine is already at the ceiling and cannot be taken further; if a listing shows 8 GB, adding a second module later replaces the existing one rather than adding to it. Check the box contents for the adapter too, since ASUS states that whether one ships depends on the country, region and model.

Key features explained
A 15.6-inch anti-glare screen
The panel is full HD at 1920 x 1080 on a 16:9 15.6-inch diagonal, with 250 nits of brightness, 45% NTSC colour coverage and an anti-glare coating. It is a matte, non-touch display: fine for documents and streaming, and the matte finish is what keeps reflections down in a bright room. It is not a colour-work panel, and ASUS does not claim it is.
U-series processors, and what that means for speed
All three chips ASUS lists are U-series parts, which is Intel’s lower-power laptop line rather than the H-series used in heavier machines. They are built for battery life and quiet fans, and they handle documents, browser tabs and video calls comfortably. What they are not is a gaming or video-editing engine — there is no discrete graphics option on this sheet.
One memory slot with a hard ceiling
Memory is 16 GB of DDR4 with a 16 GB maximum, in a single SO-DIMM slot. That is enough for the way most people use a laptop this size, but it means the machine is not upgradable beyond what it ships with. Buyers who expect to add memory in two years should know that on this model there is nowhere to add it.
Iris Xe only when memory runs in dual channel
ASUS states that Iris Xe graphics appear only on Core i5, i7 or i9 models configured with dual-channel memory; otherwise the laptop uses Intel UHD Graphics. That is worth checking on the exact build you are considering, because the integrated graphics badge affects light photo work and video playback more than everyday browsing.
What 250 nits and 45% NTSC mean in practice
250 nits is an indoor figure. It is comfortable in an office, a classroom or a kitchen table, and it holds up in a car or on a train. Outdoors in direct sun it will look washed out, which is true of most laptops at this level and is the honest reason to think twice if you plan to work on a patio.
45% NTSC is the colour figure ASUS publishes, and it is the one that matters if you edit photos or grade video. A panel at this coverage shows a narrower range of colour than a wide-gamut display, so work that depends on accurate colour should be done on an external monitor. For documents, spreadsheets and streaming, the number is irrelevant.
The ports, and what the USB-C port cannot do
There are three USB-A ports: two at USB 3.2 Gen 1 speed, which is 5 Gbps, and one at USB 2.0. Alongside them sit a single USB-C port at 5 Gbps, an HDMI 1.4 output, a 3.5 mm combo jack and a barrel connector for the power adapter.
The USB-C port is data only on this model. ASUS lists no DisplayPort alt mode and no USB Power Delivery, so it will not drive a monitor and it will not charge the laptop. A monitor goes on the HDMI 1.4 port, which tops out below the HDMI 2.0 and 2.1 standards used for high-refresh 4K, and charging goes through the supplied barrel adapter.
Battery, adapter and the 42 Wh ceiling
The battery is a 42 Wh three-cell lithium-ion pack, charged by a 45 W adapter at 19 V and 2.37 A with a 100-240 V input. 42 Wh is a modest capacity for a 15.6-inch machine, and ASUS does not publish a runtime figure for this model on the specification page, so there is no claim here to compare against.
What that means for a buyer is simple: plan on keeping the adapter nearby for a full working day, and treat the laptop as a plug-in-first machine that can move between rooms unplugged. The adapter itself is small enough to travel with, when one is included — ASUS states that inclusion varies by country, region and model, so check the box contents on the listing.

Buying the Vivobook 15 (X1504VA) in the US
Start from the model string and the listed processor, then work outwards. The same X1504VA name covers a Core i3, a Core i5 and a Core i7, with either 512 GB or 1 TB of storage, so two listings that look identical can differ by hundreds of dollars of hardware. If the listing does not name the processor, ask before ordering.
Then check the small things that are easy to miss: whether the build has a backlit keyboard, whether a power adapter is in the box, and which colour the chassis is. None of those change how the laptop performs, and all of them change whether it feels right on day one.
Frequently asked questions: Vivobook 15 (X1504VA)
What processor does the ASUS Vivobook 15 X1504VA use?
ASUS lists three 13th Gen Intel Core U-series chips for this model: the Core i7-1355U, the Core i5-1334U and the Core i3-1315U. Which one you get depends on the configuration, so check the exact build in the listing.
Can you upgrade the memory in the Vivobook 15 X1504VA?
There is one DDR4 SO-DIMM slot and ASUS lists a 16 GB maximum. A machine that ships with 16 GB is already at the ceiling, so replacing the module is the only route and it buys no extra capacity.
Does the USB-C port on the Vivobook 15 X1504VA support charging or a monitor?
No. ASUS lists the USB-C port as USB 3.2 Gen 1 at 5 Gbps for data only, with no DisplayPort output and no power delivery. Video goes out over HDMI 1.4 and the laptop charges from its barrel adapter.
Is the Vivobook 15 X1504VA display a touchscreen?
The panel ASUS specifies for this model is a 15.6-inch full-HD LED-backlit anti-glare display and it is non-touch.
Does the Vivobook 15 X1504VA have a backlit keyboard?
ASUS lists a chiclet keyboard with 1.4 mm key travel and does not list a backlight for the X1504VA column of its specification table, although other X1504 models do offer one. Confirm it on the exact listing if a backlight matters to you.
How big is the battery, and is a charger included?
The battery is a 42 Wh three-cell pack and the adapter ASUS lists is 45 W with a 100-240 V input. ASUS states that whether a power adapter is included varies by country, region and model, so check the box contents before ordering.
What storage options does the Vivobook 15 X1504VA offer?
A 512 GB or 1 TB M.2 NVMe SSD on PCIe 3.0, with one M.2 2280 slot on PCIe 4.0 x4 for expansion. ASUS lists the slot, not a second drive in the box.
Does the Vivobook 15 X1504VA have Wi-Fi 6?
Yes. ASUS lists Wi-Fi 6 at 802.11ax in a 1x1 configuration with dual-band support, alongside Bluetooth 5.2.
