Acer Aspire e14 e5-473g-304w no display only blue light when turned on

Did you try the other info, listed at the end? Of course you would have to charge it first (you said is dead, assuming you mean no power). Now if it won't charge, or turn on at all (not just the display), then I would have a tech look at it.
Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.

I tried plugging the hdmi to external monitor still no response. Can't I do anything? I was doing excel then suddenly it just turned off on its own then now it's dead.
