beginner Questions
What steps do you take when a user reports that their computer won't turn on?
beginnerFirst, I ask the user to check if the power cable is securely plugged in and try a different outlet. Next, I verify the power button and any indicator lights. If it's a laptop, I check the battery and charger. Then, I guide them through a hard reset by holding the power button for 30 seconds. If that fails, I suspect hardware issues like a failed power supply and arrange for on-site diagnostics.
