I'm usually comfortable with repairs but I cannot make sense of this behavior at all, it just happened overnight>pressing the power button does nothing>when plugging it into an outlet, after 3 seconds the power LED turns on as if the laptop was switched on, which is not supposed to happen>charging LED stays off>no fans, no POST, no sign of life>connecting an external monitor shows no image>USB ports get power as normal>when the power button is long pressed to hard reset while plugged it, it turns off for 3 seconds, then turns on again>when unplugged, the power LED used to stay on until you hard reset it, but it no longer even does that, it just dies instantlySo far I've tried>hard reset>charging it overnight>completely discharging the battery, disconnecting it, disconnecting CMOS, leaving it overnight, then turning it on again>swapping the RAM stick to the other slotIs it dead?
