Turning on your Dell computer using the keyboard might seem like a minor feature, but it can be incredibly convenient. It saves you from reaching for the power button, especially useful in situations where the computer is tucked away or the power button is difficult to access. This comprehensive guide will walk you through the various methods and settings involved in enabling this functionality. We will also cover troubleshooting steps if you encounter any issues.
Understanding Wake-on-LAN (WOL) and Keyboard Power-On
The ability to turn on your Dell computer with the keyboard relies on two primary technologies: Wake-on-LAN (WOL) and specific BIOS settings that allow the keyboard to trigger the power-on sequence.
WOL is a networking standard that allows a computer to be turned on or woken up from a low-power state by a network message. While WOL primarily involves network signals, some BIOS implementations extend this capability to include keyboard input as a wake-up source.
The BIOS (Basic Input/Output System) is the firmware that initializes the hardware during the boot process. It contains settings that control various aspects of the computer’s behavior, including power management and wake-up sources.
Enabling Keyboard Power-On in BIOS Settings
The most crucial step in enabling keyboard power-on is configuring the BIOS settings correctly. Here’s a detailed guide on how to access and modify these settings:

First, you need to access the BIOS setup utility. Power down your Dell computer completely. Then, turn it back on. Immediately after powering on, repeatedly press the designated key to enter the BIOS setup. The key varies depending on your Dell model. Common keys include F2, Delete, F12, or Esc. Watch the screen during startup for a prompt indicating the correct key.
Navigating to Power Management Settings
Once inside the BIOS setup, use the arrow keys to navigate through the menus. Look for sections related to Power Management, Advanced Power Management, or Wake-Up Options. The exact names and locations of these settings may vary depending on your Dell model and BIOS version. Refer to your Dell computer’s manual for specific instructions if needed.
Configuring Wake-Up Source
Within the Power Management section, look for options like “Wake on Keyboard,” “Power On by Keyboard,” or “Keyboard Wake-Up.” Enable this option. Some BIOS versions may offer more granular control, allowing you to specify a particular key or key combination to trigger the power-on sequence.
There might be options like:
- Keyboard Power On: Enables the keyboard as a wake-up source.
- USB Wake Support: Enables USB devices, including keyboards, to wake the computer.
- KB Password Power On: Allows you to set a password that must be entered on the keyboard to turn on the computer. This is a security feature.
Enable the relevant options that pertain to keyboard power-on.
