From reading a couple old threads here, I am starting to think that my laptop turns off randomly because of a bad fan. So I checked under my laptop, and I can't feel air flow from anywhere, nor do I see a fan spinning. I have a satellite a105-s4284. I am including a picture of the bottom of the laptop, where I have circled where I believe the fan to be. It is not spinning. Should it be spinning at all times, at least to some extent? If this is where the fan is located, then I definitely need to order another one. Thanks for the help! ugh, well i can't post a picture, because my post count is too low. but just confirming that the fan should be spinning at all times should suffice.
