My Acer laptop Aspire F15 - F5-573G-556W has these problems:
1. Sometimes, the screen turns black suddenly, it even happens faster when I am gaming. When screen turns black, the fan is still running and spinning, however the playing background music stops. What I have done is to force shut down by holding the power button.
2. Sometimes, when I start up my laptop again, the fan is running and spinning at a very high speed, but the screen remains black. I forced to shut down my laptop and tried again.
3. Sometimes, my laptop couldn't wake up from sleep. The power LED lights up, but the screen remains black. Again, I have to force to shut down my laptop.
I have sent my laptop for warranty repair for three times. However, these problems still happen.
