Problem with power button LED?
There’s an issue with the LED light on my PC’s power button. For months, it has been flickering—dim and then brightening again. Recently, it completely stopped working, though it briefly came back after a few minutes. I checked the case but found no loose connections. The system runs fine on its own. I think the LED bulb is gradually failing, but I’d appreciate your advice.
You could contact the case manufacturer to confirm if a replacement button exists.
It might be useful to buy an inexpensive external power button with an LED to test whether the problem lies with the motherboard.
In practice, even if it fails, it shouldn't affect operation much. If you lack other lighting options, there are various add-on kits available that support ARGB or strip lights, allowing you to assess power supply from another source.
Typically, there are distinct motherboard connections for the Power Button and the Power LED. Therefore, your power switch with both will have two lead pairs coming off of it—ensure the LED one hasn’t drifted away.
You might check the light in your button by briefly connecting it to the HDD LED connection, which is clearly functional in your video.
I experienced the same problem with the Power LED on a 10-year olf media player PC. The blue LED would flicker, stop working, and then restart after a week. Eventually, I replaced it with an older green LED from my spare parts box, soldering it onto the flying lead. The new LED was much less intense and reduced eye strain while watching TV. If you're skilled at soldering, a replacement costs about $0.10 to $0.50, depending on the type and color. If the LED is part of the switch mechanism, a new illuminated switch could cost around $5. The key is finding one that fits the front panel hole.
The HDD LED is the red one. I'm sure the connectors are properly connected because
1. I built the PC a few years ago and followed the motherboard's instructions.
2. It has been several months since the LED issue began. Before that, everything functioned correctly.
Replace the power switch plug/plugs on the motherboard...test.
