When you write "time to open" I assume you mean the system boots up and loads your OS, but suddenly it shuts down. Is it correct?

If so, check you system fan, because the problem seems to be caused by an overheating and the laptop shuts down to prevent damages.

Other thing you can check is the thermal paste condition, or even if the heat sink is correctly screwed to the mounting holes.
