I have the Acer Aspire 5 A515-51G-58EY, this Laptop has 2 VGAs the first one (intel hd 620 or 720 ) works in general use .When you play a game the MX150 turns on. The problem is that sometimes when the MX150 is on the laptop make the exact same black screen(1 second) with the black screen whenever you connect the battery adaptor /charger. This one second black screen is not a problem but that continues 3-4 times and the adaptor stop working( i play with battery-the performance of the laptop sucks whenever its in battery mode nad makes me really dizzy ) and the 2 small lights( blue and orange) start blinking. In some articles i have read that i should turn off and turn on the battery from the back of the laptop with a small pin but i dont usderstand . Thanks for your time
