Bug Description

Hi,
I have a DELL Inspiron 15 7000 series 7548.
I have always used a dual boot system with Ubuntu 16.04 and Windows Os. It works perfectly fine except for the last few weeks when I started to encounter a following weird issue:

So, whenever I SHUT DOWN my laptop it struggles to start back on again. I can see the power light on, charging light on (if plugged) and can also hear the fan running but it does not show any boot options or does not respond to function keys, nothing. I even tried removing the battery for few minutes, removed the plug to discharge any static current just for the sake of it, but it still wont boot up.
However, after a few random attempts to POWER ON (usually takes hours) it boots back up normally and functions properly.
The laptop restarts properly, displays all the boot options and works perfectly normal otherwise.

The problem is just when you SHUT DOWN and try to power it back ON

As of now my Laptop is working fine, but I don't want to fall back in that weird scenario when I have to shut it down or the battery runs out of power.

I have attached a boot info file generated from a boot repair software app for ubuntu.

Need assistance as soon as possible.
Thanks
