hi, not sure exactly what you mean by power itself .
i have seen fan do a lot of things ,never seen one power itself ,i always had to plug them into something . most laptop fan come on for a few seconds when you first boot up ,but shut off until the laptop heats up ,they don't run all the time .

The power lead to the fan from the motherboard could have issues. If the fan works if, when out of the laptop, you apply power, but in the laptop never turns on, even at bootup, then it could be a problem with that power connector.....

Are you certain the fan doesn't spin even at bootup?

The fan run depending on heat that motherboard produces.
if it is not heated up the fan does not run.

In order to test that fan working or not is when you boot the machine the fan should run
