I purchased new Acer predator Helios 300. I am living in Germany. I bought it from Amazon US. I used a simple US to german adapter (no voltage conversion). I plugged in the laptop. Laptop not turning on. Not even the power source indication light is on in the laptop. Laptop not making any sound. Not booting up. I checked my power adapter. It is working fine with my phone charger. Please help me what might be the issue.
