ASUS B3405CAA Troubleshooting Guide

Notebook does not turn on

Connect the AC adapter securely, confirm that the outlet works, and inspect the charging indicator. Disconnect accessories, hold the power button briefly, and try starting again. If the notebook remains unresponsive, use ASUS support rather than opening the chassis.

HDMI monitor shows no image

Confirm that the cable is fully inserted and that the monitor is set to the correct HDMI input. Press Windows + P and select Duplicate or Extend. Restart the notebook with the display connected, then install current Windows and graphics updates. If possible, test another HDMI cable or display to isolate the fault.

Wi-Fi or Bluetooth cannot connect

Turn wireless connectivity off and on, move closer to the router or accessory, and remove and re-pair the device. Restart the router and notebook. If the problem continues, run the Windows network troubleshooter and reinstall the applicable ASUS wireless driver.

Notebook runs slowly or becomes hot

Close unused applications, check Task Manager for excessive background activity, install updates, and keep the air vents clear. Use the computer on a hard, level surface and scan for unwanted software.

Error codes and support

Record any on-screen error message, diagnostic code, recent hardware change, and Windows version. Error codes can differ by configuration, so do not apply a fix intended for another ASUS model. Check the official ASUS B3405CAA support page for the correct manual, drivers, service information, warranty registration, and regional contact options. Warranty coverage and service terms depend on the purchase region and product configuration.
