Frequently Asked Questions - Taichi 21-0031A3517U ASUS
How do I switch between laptop and tablet mode on the Taichi 21?
The Taichi 21 features a dual-screen design. To use it as a tablet, simply close the lid; the external display automatically activates. You can also press the Taichi mode key to switch between dual display, laptop only, or tablet only modes.
Can I use the touchscreen on both displays?
Yes, both the internal and external panels are touch-sensitive. The external panel works as a tablet screen when the lid is closed.
How do I rotate the screen orientation?
In Windows, right-click on the desktop and select Screen resolution. Then choose the desired orientation (Landscape, Portrait, etc.) or use the graphics driver settings.
How can I extend or duplicate the display?
Press Win + P to open the projection menu, then select Duplicate or Extend to configure how the two screens behave.
What should I do if the touchscreen is unresponsive?
First, ensure the display is clean and dry. Restart the device. If the issue persists, update the touchscreen driver from the ASUS support website.
How do I update the BIOS?
Download the latest BIOS from ASUS support, save it to a USB drive, enter the BIOS by pressing F2 during boot, and use the EZ Flash utility to install it.
Can I upgrade the RAM or SSD?
The Taichi 21 has a single RAM slot and an M.2 SSD. You can upgrade the RAM to 8GB and replace the SSD with a larger capacity, but be careful to use compatible parts.
How do I reset the device to factory settings?
Go to Settings > Update & Recovery > Recovery and select Remove everything and reinstall Windows. Backup your data first.
What is the battery life in real usage?
With normal office work and screen brightness at 50%, you can expect approximately 5-7 hours. The dual-screen mode uses more power, so battery life may be shorter.
How do I clean the screens safely?
Use a soft, lint-free microfiber cloth slightly dampened with water or a screen cleaner. Never spray liquid directly onto the screen; apply it to the cloth first.
