ASUS Zenbook 15 UM3504DA: Ryzen 5 laptop features, specs and who it suits

The ASUS Zenbook 15 UM3504DA-AS54 is a thin 15.6-inch laptop built around an AMD Ryzen 5 7535U processor. It is designed for people who want a large screen without much weight: study, office work, streaming and everyday computing away from a desk. Here is what its specs mean in use.

Processor and graphics

The Ryzen 5 7535U has six cores and 12 threads, with a boost clock of up to 4.6 GHz and 12 MB of cache, according to the listing. Six cores are generally plenty for web browsing, documents, video calls and light photo editing. The integrated AMD Radeon graphics share the chip and memory, so they handle video playback and casual games but are not a substitute for a dedicated graphics card in demanding titles.

Memory and storage

The laptop has 16 GB of LPDDR5 RAM soldered onto the board, with a 512 GB PCIe 4.0 SSD. Soldered memory is fast and power-efficient but typically cannot be upgraded later, so 16 GB is what the machine will have for its life. A PCIe 4.0 SSD means quick start-up and file transfers. Windows 11 Home is installed.

The display

The 15.6-inch screen is Full HD (1920 x 1080) in a 16:9 shape. ASUS calls it a NanoEdge display, meaning slim bezels, and lists 100% sRGB coverage, which suits everyday colour work. The hinge opens 180° flat, which is handy for sharing the screen across a table.

Thin, light and long-lasting

ASUS lists the Zenbook at 0.62 inches (about 1.6 cm) thick and about 3.1 lb (1.4 kg). A 67 Wh battery sits inside; actual runtime varies with brightness and workload, so treat any hours figure as a guide. The listing says USB-C ports support power delivery, so you can typically charge from a compatible USB-C charger.

Ports and wireless

• 1 x USB4 Gen 3 Type-C with display and power delivery.
• 1 x USB 3.2 Gen 2 Type-C with display and power delivery.
• 1 x USB 3.2 Gen 2 Type-A.
• 1 x HDMI 2.1 TMDS.
• 1 x 3.5 mm combo audio jack.
• Wi-Fi 6E (dual band, 2x2) and Bluetooth 5.3.

Two Type-C ports plus HDMI let you connect an external monitor while charging. ASUS notes that USB transfer speed may vary.

Camera, sound and design

An FHD infrared camera supports face login, and ASUS adds 3D Noise Reduction for video calls. The speakers are Harman Kardon-certified with Dolby Atmos. The laptop comes in Ponder Blue, with an anodized finish, and ASUS also lists a Basalt Gray option.

Who it suits

It suits students, remote workers and travellers who want screen space in a slim body, and families who want a general-purpose laptop. It is less suited to heavy gaming, 3D rendering or work that needs a large amount of RAM.

What to check before you buy

• Memory: the RAM is on board, so confirm 16 GB is enough for your needs.
• Storage: 512 GB is fine for most, but check against your files and software.
• Ports: there is no full-size Ethernet port, so a USB adapter may be needed.
• Charger: check what charger is in the box and whether it suits your travel habits.
• Software: it ships with Windows 11 Home; check that your programs support it.
• Model code: confirm the exact model, UM3504DA-AS54, against the product name.
