What happens when the computer spits out a vague error code or just blanks? I got my real training by pulling things apart and noticing details a screen might miss. Seems like without that feel for the work, you're just a button pusher who can't adapt.
Spot on. Computers fail when sensors go bad or software glitches. Like when a power supply fan dies, the system might just shut down with no clear error. You have to hear the grind or smell the burn to know what's up. Screen diagnostics miss physical clues like loose connections or corrosion. Without getting your hands dirty, you're stuck waiting for the next error code. That's not fixing, it's just guessing.
