Check the power source
Test the wall socket with another safe device. Reseat the charger at the wall and computer. For a desktop, check the power switch on the back is on.
Look and listen
Press the power button once. Notice whether lights, fans, beeps or the screen appear. This information helps identify whether the problem is power, display or startup.
Disconnect extra devices
Remove USB drives, printers, docks and unnecessary accessories, then try once more. Leave the keyboard, mouse and screen connected on a desktop.
Check the screen
Increase brightness. On a desktop, confirm the monitor is on and the cable is firmly connected. If possible, test another known-working screen or cable.
Perform a simple power reset
Turn the computer off. Disconnect power for 30 seconds. Reconnect power and try again. Do not open the case or remove an internal battery.
