Question

Answer 1

You need to check the manual of your machine. You may also check out the website of the manufacturer of you machine to know if that is a feature of your pc.

If you were not able to get information, try to call the tech support of you machine and inquire about your concern.

Answer 2

Likeliest possibility is insufficient power / too-great of a load.

For the power button, that would (easiest fix) be a disconnected wire somewhere, (hardest fix) or, a software setting that has been FUBAR'ed.

When you dusted the case, depending on *how* you did it, you may have jiggled something that shouldn't be jiggled.

Final possibility *I* can think of is it is unusually hot where you are, and your computer is shutting down due to extreme heat load. It's a safety feature that most people will rarely (if ever) encounter designed to prevent to CPU from being fried outright.

Answer 3

first check the battery, try 2 go in to safe mode 2 C if the screen saver setting has been changed 2 shut down sooner. I only seen that type of switch on MAC's
