When the power button is pressed keyboard lights up and the screen turns on (without showing anything) a few seconds later keyboard lights turn off as well as the screen turns off leaving the light on the power button and cap lock key on they turn off few seconds later. The only solution is to repeat press the power button and hold it down to restart and do this until it turns on.

Given the date of your post, I would have expected someone to respond to it before this -- but since that has not happened, I will take a shot at it ...
Win10 has enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT.
This is different from Fast Boot, which is a BIOS/UEFI option.
Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off.
Disabling Fast Startup might fix the booting problem.
There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.
Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup
Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F
In both cases, reboot Windows.
NOW, FastStartup is disabled.
See if that helps.
