So ive just received a new Asus X555U laptop today, and upon opening it and plugging it in, it neither turns on, nor shows any indication of charging on the LEDs. When plugged in the lightbulb and airplane mode LEDs flash for a second, and then go blank again, without the charging led turning on or doing anything at all. I’ve read a few posts about unplugging it and holding the power for 60 seconds to flush residual power but that hasnt done anything for me so far.
