For Online Computer Support, Ask a Computer Technician
My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
Lets try a hard reboot first please> Sometimes this is caused by a glitch in the firmware and can be resolved by a forced reboot, other times it is due to failed hardware, if it is a glitch then your Laptop will work normally again. Disconnect the power cord and any other externally connected devices and usb cables, then Press and hold the power button down for 60 seconds. Let me know if any changes occur.
