      Amy PonceJul 30, 2025
      If your Acer Laptop won't turn on, ensure the power cable is properly connected to both the laptop and the electrical outlet. Remove any extension cables or surge protectors between the laptop and the outlet, and plug the laptop directly into a known working electrical outlet. Disconnect the power and open the casing to check the thermal unit and fan airways are free of obstructions. Also, remove all external and non-essential hardware that are not necessary to boot the computer. Finally, remove any recently installed software.
