How to Turn on a Computer Without a Power Button

If the power button on your desktop computer is difficult to reach, turning on your system in the usual manner might be inconvenient. Fortunately, most modern desktop computers allow you to power up the machine merely by pressing a key on the keyboard. If your computer has a PS/2 keyboard, turning on the machine without using the power button is relatively easy to set up.

Things You'll Need

• PS/2 keyboard or USB keyboard with PS/2 adapter

Instructions

1. Turn off your computer. Restart the system and press the "Delete" or "F2" key as soon as the first boot screen appears. Wait for the BIOS menu screen to display.

2. Provide your computer's BIOS password if prompted to do so. Use the arrow keys on your keyboard to navigate to the "Advanced" or "Advanced Settings" menu, then press the "Enter" key.

3. Press the "down-arrow" key and move the cursor to the "Power Management" or "ACPI Management" setting, then press "Enter." Position the cursor over the "Wake on Keyboard" or "Power on by Keyboard" option.

4. Press the "+" key to change the field setting for the "Wake on Keyboard" or "Power on by Keyboard" value to "Enabled."

5. Press the "F10" key to save the BIOS setting changes and exit the setup menu. Wait for the computer to restart.

6. Press and hold the power button on the computer for approximately five seconds. The computer shuts down again.

7. Press any key on the keyboard. The computer will boot up without you having to push the power button.
