ASUS laptops troubleshooting

Published specification

What is true of this model and changes how you fix it

• Official specifications
  Intel Core Ultra 7 258V / Ultra 7 356H / Ultra 9 386H options. Up to 32GB soldered LPDDR5x-8533. 14in 3K OLED touchscreen. All-metal chassis at just 1.2kg / 2.65lbs, 1TB PCIe Gen 4 SSD.
• Tier — premium ultrabook AI PC (Windows 11)
  A thin premium Windows 11 ultrabook (Copilot+ AI PC with an NPU) and an OLED display — for everyday and office work with long battery. Not a gaming machine.
• Copilot+ AI + thin thermals
  Copilot+ AI features need Windows updates/rollout (a missing one is software timing, not a fault). As a thin ultrabook it can warm and throttle under sustained load, which is expected.
• OLED care & ports
  OLED can show temporary image retention that clears (use dark mode/auto-hide taskbar). USB-C/Thunderbolt plus usually HDMI/USB-A.
• The OLED featherweight
  The Zenbook S 14 is ASUS's thin OLED laptop with an Intel Core Ultra chip, built for long battery life and light carry. It leans on MyASUS for firmware and battery care.
• What owners run into
  Reports include a battery that drains faster than expected, a display that flickers at low brightness and a charging port that is sensitive to the adapter.
• How to approach a fault
  Use MyASUS to update firmware and enable battery care.
• Finding your model
  The model number is on the base and in MyASUS.
• Battery care
  MyASUS offers a battery care mode that caps the charge at 80 percent to extend the cell's life, which suits a laptop used mostly on a desk.
• Display and OLED
  OLED screens show true blacks but can retain an image if the same content is static for hours. Use a dark theme, auto-hide the taskbar and set a screen saver.
• A thin ultraportable
  The ASUS Zenbook S 14 is a thin laptop with an OLED display and an Intel Core Ultra processor, built for travel and office work. The OLED panel has deep contrast and is glossy, so use it away from windows and set a short screen timeout to avoid retained images. Its ports are limited, with Thunderbolt-class USB-C and an HDMI output, so a hub helps. The aluminum body is light and flexes under pressure, so carry it in a sleeve rather than a crowded bag. MyASUS is the control app for battery care, fan modes and updates, and the Battery Care setting limits the charge to extend the battery's life.
• When something is wrong
  If the laptop is slow, check that it is not in a quiet power mode, that the drive has free space and that no process is using the processor. If it will not charge, test the charger with the laptop off and try both USB-C ports. The MyASUS diagnostics test the battery, display and storage, and give a result you can quote to ASUS support with the serial number from the base.
