How to enter your PC's BIOS
Image: IDGBIOS stands for “basic input/output system.” This software checks the health of your computer’s hardware and allows Windows to start. When you turn on your PC, its BIOS runs a power-on self-test (POST) to ensure that the machine’s devices (hard drive, sound card, keyboard, and the like) are connected and working properly. If the test finds no problems, the BIOS turns over control of your PC to another piece of software, typically the operating system.
Every PC has a BIOS, and you may need to access yours from time to time. Inside the BIOS you can set a password, manage hardware, and change the boot sequence. The BIOS user interface is straightforward and easy to access, but you should take caution when exploring the BIOS–don’t change settings if you don’t know what they do.
Step by Step: Entering the BIOS
1. Get ready to act quickly: You need to start the computer and press a key on the keyboard before the BIOS hands over control to Windows. You have only a few seconds to perform this step.
2. Boot (or restart) the PC: Pay close attention to the first screen that appears. Look for a message that indicates which key you need to press in order to access the BIOS. That key is likely to be:
–A Function key (such as F1, F2, or F3)
–The Esc key
–The Delete key
IDGOn this PC, you’d press F2 to enter the BIOS setup menu.
On some PCs, entering the BIOS may require pressing another key or a combination of keys. Keep your eyes open for an on-screen message that says something like:
–‘Press F1 to enter setup’
–‘BIOS settings: Esc’
–‘Setup = Del’
–‘System configuration: F2’
If you don’t catch it the first time, simply try again. Your computer’s documentation may also tell you which key to press.
3. When you know the right key, start the computer again and press the key when the first screen pops up: You may hear a confirmation beep or see a new message. If you timed it correctly, you’ll be in the BIOS within a few seconds.
