I apologize for the inconvenience you’re facing with your ***ASUS Zenbook Pro 14 Duo OLED (UX8402)***. Let’s troubleshoot this issue together:
# ***Power Button Check***:
** The power button is crucial for turning on your laptop. If it’s malfunctioning, it can cause startup issues.
** Before considering hardware replacement, try the following:
*** ***Press and hold the power button***: Sometimes, a long press (about 10 seconds) can force a hard reset.
*** ***Check the AC adapter***: Ensure its connected properly and providing power.
*** ***Inspect the power LED***: Look for any signs of life (even brief flashes) when you press the power button.
# ***Alternative Power-On Methods***:
** Unfortunately, the Zenbook Duo primarily relies on the power button for startup.
** ***CMOS battery removal*** won’t directly affect the power button functionality. It mainly resets BIOS settings.
** If you suspect the power button, consider seeking professional repair or contacting ASUS support.
# ***Changing the Power Button***:
** Replacing the power button involves disassembling the laptop, which can be complex.
** ***Disassembly guide***:
### ***Remove the bottom plate***: Undo the screws and gently pry the bottom panel away from the chassis.
### ***Locate the power button assembly***: It’s usually near the top of the keyboard area.
### ***Disconnect the power button cable***: Carefully unplug the cable from the motherboard.
### ***Replace the power button module***: Install a new power button module (if available).
### ***Reassemble the laptop***: Secure the bottom plate and tighten the screws.
# ***Professional Assistance***:
** Given the intricacies of laptop internals, I recommend seeking professional help.
** An authorized ASUS service center can diagnose and repair the issue effectively.
Remember to back up your data if possible before any repair attempts. I hope your Zenbook Duo powers up smoothly soon.
