Turns on but shuts itself right away

I can turn on my MacBook, after the apple sign shows up for a minute or so it just shuts itself off.

When I last use my computer it was fine, instead of shutting it off the safe normal way I hit the power button, the screen went off but it didn't shut off so I held the power button till it shuts off.

Now I don't know what to do to keep it stay on, please help! I've been looking up some forums and tried option+command+P+R while I tried to turn it on but no luck!

Answer this question I have this problem too

Is this a good question?

If you're comfortable opening your Mac, I would unplug the battery for about 20 seconds, then try rebooting again. I know this is a silly question, but is the machine charged?

Yes, the machine's almost fully charged, I'll try to get the tool to open it and see how it goes, thanks!
