ASUS Zenbook 15 OLED UM3504DA-DS76 Laptop

Weight might vary according to specifications.

The visual appearance of OLED displays may change over the product’s lifetime. This is expected behavior that can include image persistence or burn-in, where the display shows a faint remnant of an image even after a new image appears on the screen. This tends to occur only in extreme use cases, such as when a static, high-contrast image is continuously displayed for prolonged periods of time. ASUS laptops with an OLED display minimize this risk by setting Windows’s Dark mode as default, as well as shortening the idle time before the screen is turned off — both on mains (AC) and battery (DC) power. This dual approach minimizes the potential for burn-in to maximize the lifespan of your OLED display lifespan, and also reduces unnecessary power draw for optimal battery life. We also recommended adjust the brightness of your OLED display to complement the ambient lighting in your environment, rather than keeping the screen at maximum brightness at all times. You should also ensure that you have an animated, dark-background screensaver enabled in the Windows Settings tool.

The testing regime includes the requirements of both military-grade standards and ASUS quality tests, and varies depending on device. MIL-STD-810 testing is conducted on selected ASUS products only. Note that the MIL-STD-810 testing helps to ensure the quality of ASUS products but does not indicate a particular fitness for military use. The test is performed under laboratory conditions. Any damage caused by attempts to replicate these test conditions would be considered accidental, and would not be covered by the standard ASUS warranty. Additional coverage is available with ASUS Premium Care.

Clinical testing using the ISO 21702 and ISO 22196 standard protocol proved that viral and bacterial growth were inhibited by 99% over a 24-hour period. A 99% reduction in potentially harmful microorganisms is defined as the number of viruses and bacteria on the surface dropping from 1,000,000 (cfu/pfu) to 100 (cfu/pfu).

This bath-based method produces a physical and chemical transformation of the aluminum, which transform the metal into a plasma ceramic aluminum, primarily to give metal alloy a longer lifespan by making it harder and more resistant to wear.

The hardness tests were conducted by ASUS on 31st October, 2022. Test configuration: Zenbook UM3504 Basalt Gray model. Test settings: 765 g pencil to scratch the chassis while the pencil tip and laptop surface form a 45^° degree angle, No discernible scratch was left on the surface.

WiFi 6E availability may vary by country and their specific regulations. Feature only supported by Windows 11 or later.

WiFi Master Premium might vary by specifications.

Compared to an average LCD laptop panel. Average LCD display has a 10 ms response time.

Compared to average LCD displays in the market, measuring energy emission of blue light in between 415-455 nm wavelength.

Battery tests conducted by ASUS on February 21, 2023 using the MobileMark^® 2018 Office Productivity scenario. Test configuration: Zenbook UM3504DA IPS panel, UMA, 256GB SSD, 8 GB RAM. Test settings: WiFi enabled but disconnected (not connected to any access point), Windows Power Plan set to Balanced, display brightness set to 200 cd/m2. Actual battery life may vary depending on product configuration, usage, operational conditions and power management settings. Battery life will decrease over the lifetime of the battery.

The charging speed of a Power Delivery charger will match the connected adapter’s power output, up to a maximum of 100 watts. USB-C^® Easy Charge provides 4.5-watt charging when connected to a non-Power Delivery charger, including most portable and USB Type-A to USB-C^® chargers. Some portable chargers may not support such features, depending on the configuration.

Unless otherwise stated, all performance claims are based on theoretical performance. Actual figures may vary in real-world situations.

The color-temperature-adjustment feature is available with OLED models only.

ISO 21702 specifies proper methods for measuring antiviral activity on plastics and other non-porous surfaces of antiviral-treated products. Test Viruses used in this International Standard are as follows: Influenza: An enveloped virus known to cause respiratory tract infection in humans. Feline calicivirus: A non-enveloped virus used in place of noroviruses known to cause enteric pathogens due to similar biological properties.

ISO 22196:2011 specifies a method of evaluating the antibacterial activity of antibacterial-treated plastics, and other non-porous, surfaces of products (including intermediate products).

Clinical testing using the ISO 21702 and ISO 22196 standard protocol proved that viral and bacterial growth were inhibited by 99% over a 24-hour period. A 99% reduction in potentially harmful microorganisms is defined as the number of viruses and bacteria on the surface dropping from 1,000,000 (cfu/pfu) to 100 (cfu/pfu).

COVID-19, H3N2, H1N1, E. coli and Staphylococcus tests were performed by independent third-party laboratories: Boken Quality Evaluation Institute, Japan Textile Products Quality and Technology Center, and National Defense Medical Center.

Antimicrobial treatments are manufactured by Co-Action Corporation.

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is the Federal statute that governs the registration, distribution, sale, and use of pesticides in the United States.

The Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) concerns the placing on the market and use of biocidal products, which are used to protect humans, animals, materials or articles against harmful organisms like pests or bacteria, by the action of the active substances contained in the biocidal product.

Note that the protective effects of ASUS Antibacterial Guard were tested by ASUS on April 26, 2021, and follow the ISO 22196 method on our specially-treated test samples. The tests provide a simulation of three years of wear and tear, and include exposure to salt spray, thermal shocks, and both alcohol and wool-felt tests. Actual effective antibacterial-protection period may vary depending on product configuration and usage.

The actual composition of ASUS Antimicrobial Guard Plus may vary.

ASUS Antimicrobial Guard Plus is applied on the laptop areas that users touch most frequently, including the palm rest area, keyboard, touchpad and power button/fingerprint sensor. A sticker on the laptop will help to identify the device is covered by Antimicrobial Guard Plus or Antimicrobial Guard due to different spec configuration.

EPEAT registered where applicable. EPEAT registration varies by country. See www.epeat.net for registration status by country.

Percentage varies according to device configuration.

Selected products are tested using enhanced military-grade MIL-STD-810H durability standards, with 12 test methods and 26 test procedures, to ensure extraordinary toughness. Based on ASUS internal market research using available information and testing reports from main laptop brand websites on October 28, 2022, ASUS consumer laptops use a regime consisting of 26 test procedures, which is the consumer laptop industry’s strictest and most extensive test regime for the MIL-STD-810H standard.
