Black screen but not completely
Hi guys! I don't know if this case is specific. When I turn on laptop it starts normally but before booting completely it goes black. I repeat it several times (Iafter shutdown with power button) and it works . Sometimes it goes black during the work, sometimes just flickers. But what I noticed today is that when it goes black of I direct mobile phone's light into screen, I can see icons or whatever I was working on during the time it went black. I guess this was answered before but I could not find the answer. Thank you in advance for your answers.
Is this a good question?
