Hello, As mentioned above, I have a local brand laptop and i'm facing "black screen" issue while trying to boot. There's power but nothing happens after pressing the button but fan runs all the time.
AFAIK, the problem is not the ssd, not the power supply or battery. I couldn't have a chance to try Ram.
And I want to give a specific info that may have something in common with the problem, there are a couple of touch buttons on laptop. Normally their blue led must start immediately but now it takes almost 10 seconds to work! And leds don't start working together, they start one by one... Sorry for bad language hope I explained it well. Thanks in advance...
