PC goes to boot menu after waking up from sleep

Question

I've been using xubuntu 16.04 since it came out. A couple of month ago I decided to install it on my laptop along with windows 10. The problem I faces has been around since the beginning of dual OS. Every time I put the computer to suspend and then decide to wake it up it goes automatically to boot menu (grub). when I wake the pc up I have to use the power button because it won't answer to keyboard and the mouse which I think is very strange. I suspect that it is something wrong the grub. I remember once I tried to use "sudo update-grub" and nothing happened. here is some specifications if needed:

Here is the /boot/grub/grub.cfg

my PC is a laptop hp probook 650 with onboard graphics

/etc/default/grub
