Laptop not charging. Acer concept 3D.
Serial number: D1EW14A001B
We have 2 Acer concept 3D laptops, my sister used my charger in the morning and around 1 hours ago, I plugged it into charge my laptop but it simply didn't work. I tried checking it on my sister's laptop, but it didn't work on her laptop as well. We only have a single charger. There are no signs of burn or cuts on the charger. What should i do?
