Inspiron 15-3543 (2015), 3 beeps
Hello,
Please I need your help. The laptop suddenly doesn't open and it has 3 beeps. It worked for hours then stopped with no sounds, nothing on screen, just the power lamp open. I tried to take off the adapter and battery and press on the power but nothing happened.

If you're able to boot back into windows, updated the BIOS and drivers, and computer is working normally:
Run a full (Complete) diagnostic test to check hardware on the system. This will run a stress test on all hardware devices which goes even deeper to find any possible hardware issues . Please follow steps in Dell video below:
