I was opening up a laptop of mine which has been a constant workhorse clocking at least 12+ hours on average for almost every single day for the last 3yrs. Recently it started acting up with fans running full throttle even on light load. Well, the culprit it turned out was that most vents and fans were caked with dust and grime over the years. A quick clean-up of all that dust improved the situation to an extent(To get it back to normal, I would probably have to remove the heatsinks and apply the new thermal paste for better heat transfer).
What I want to stress today is not the solution but the act of finding the solution. You have to be naturally curious about the surroundings around you. Ask probing questions first. There is a skill in that. Asking the right questions is half the battle. Question anything and everything around you. Case and point, when my laptop was acting up, I was wondering what changed? Why are the fans on full throttle? What could be the reason? Is it something that I did recently? When you ask the right questions, it will open up new dimensions, finding solutions to those questions is a relatively easy task with the wealth of information at your fingertips. Start learning to ask the right questions. It will help you learn so much.
