Question I have a acer aspire 3 screen stay black

[Imogena]

I have a acer aspire A315-56-79D4 model N19C1. When I turn the laptop on I get 2 blue lights. That shows there is power. And the fan turns on. But there is no lights on the keyboard. An external screen shows the same and nothing happens with a hard reset. Even when plugging in a usb keyboard no lights. Please help

You might want to disassemble the bottom part of the laptop, then remove the memory, wipe the gold contacts of the ram with an eraser, wipe clean. Press and hold down the reset button on the bottom of the laptop(to disconnect to battery power to the laptop) and then replace the ram, see if that helps revive the laptop.

I've removed and cleaned every thing. But the motherboard has 4 gig ram soldered onboard that I cant remove
