Product type	Where to look
Computers, Printers & Office	Printers usually have the label inside the front access door or on the back. Laptops have it on the underside. Monitors put it on the back panel near the stand.
Routers & Networking	Flip the router over. The label on the bottom has the model, hardware version, default Wi-Fi name, and often the admin login address.
Game Consoles	Consoles print the model on a label on the back or bottom. The system settings also list it.

Getting the official ASUS manual

ASUS publishes product documentation on asus.com. Search there with the full model number from the label, then look for a documents, manuals or downloads section on the product page.

If your model isn't listed, try removing the last few characters, which usually only indicate color or region. For discontinued models, look for an archive or legacy products section, or contact ASUS support directly.
