You press the power button and absolutely nothing happens. No lights, no fan spin, no sound. It's completely dead.
Try these safe checks first:
Check if the charging light turns on when plugged in
Try a different wall outlet
Hold the power button for 30 seconds (Hard Reset)
Check the charger cable for any damage
Remove the battery (if removable) and try just the charger
What's likely happening?
This usually means power isn't reaching the motherboard, or the motherboard itself has a fault. It could be as simple as a dead charger, or deeper like a short circuit protecting the system from turning on.
