SUMMARY

The discussion focuses on testing the LED in the power button of an Acer 7750G laptop running openSUSE 13.2. Users suggested two primary methods: using a battery cell with wires to directly power the LED and employing a multimeter set to the Ohm function to check the LED's functionality. Caution is advised when handling surface-mount device (SMD) LEDs due to their delicate nature. The user expressed a lack of time to explore these methods further.

PREREQUISITES
  • Basic understanding of electronics and LED functionality
  • Familiarity with multimeter usage
  • Knowledge of openSUSE 13.2 operating system
  • Experience with soldering and handling SMD components
NEXT STEPS
  • Research how to use a multimeter for testing electronic components
  • Learn about SMD LED specifications and handling techniques
  • Explore troubleshooting methods for laptop hardware issues
  • Investigate software tools for monitoring hardware indicators in openSUSE
USEFUL FOR

This discussion is beneficial for electronics enthusiasts, laptop repair technicians, and users of Acer laptops seeking to troubleshoot LED issues effectively.

Hi

I'm not having a huge problem, but it bothers me.
Today I noticed the indicator led in my power button doesn't work.

I'm using an Acer 7750G laptop not entirely sure how old (funny how quick we forget and get used to such things).
Is there any software method of testing this LED?
I'm using openSUSE 13.2

A quick(ish) google search didn't amount to any useful information since the results always treat laptops not powering on.

If you are familiar with measuring procedures you can shutdown your laptop and use some wires connected to a battery cell to see if the LED lights up. You may also use a multimeter set on the Ohm-function. Proceed with care if the LED is of SMD type.
 
Well this will be put on the back burner then.
I don't have the time to learn about this now. (not really familiar with this stuff)

Thanks for the answer and I will revisit this if I ever get an answer!
