Technological problem?

My laptop turned off the same every half hour

Can you please formulate a reasonable sentence?

Pardon me for my language but my laptop doesn't run well every half hour shutdown

Okay, there can be several reasons, you can't judge that from a distance.

Enough battery?
Does the power supply (charger) work?
Battery still working?
How old is the laptop?
Which manufacturer and which model? (preferably model number)
Laptop fallen down?
Windows or iOS settings checked?
Virus scanner installed?
Other damage to the device?
Something wrong with the software?
other details?
