Does it happen while the charger is connected or not? Here are some troubleshooting steps that may help.
- First do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If it will still not work, remove the battery off the laptop then connect just the AC adapter and see if the same problem will persist or not.
- If it will still not work and if the laptop is still under the factory warranty do contact ACER for a repair since there might be a grounded part inside the laptop.
