For most Lenovo computers, the primary key used to access the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is F2 or a combination involving F2.
Accessing the BIOS on Lenovo Devices
The specific key or method can vary slightly depending on the model and series (like ThinkPad, IdeaPad, Legion, etc.), but the reference material confirms a common approach:
- Press F2: On many Lenovo laptops and desktops, you need to press the F2 key immediately and repeatedly as soon as you power on the device.
- Use Fn+F2: Some Lenovo keyboards have function keys that default to media controls. In this case, you might need to hold down the Fn key and then press F2 (Fn+F2).
According to the provided reference, accessing the BIOS may take multiple attempts, so keep trying if it doesn't work the first time.
Common Keys and Methods for Lenovo
While F2 and Fn+F2 are the most common as noted in the reference, Lenovo devices sometimes offer alternative ways or other keys, especially on newer models or during startup options.
Here's a summary of keys often associated with Lenovo startup:
- F2 or Fn + F2: The standard key to enter BIOS/UEFI setup.
- F1: Sometimes used to enter BIOS on older ThinkPad models.
- F12: Typically opens the Boot Menu (allowing you to choose the boot device like a USB drive or DVD).
- Enter: On some ThinkPad models, pressing Enter at the Lenovo splash screen may give you an option to access setup (BIOS) or the boot menu.
- Novo Button: Many IdeaPad and some Lenovo desktops have a small Novo button (often looks like a small arrow). Pressing this button while the computer is off can bring up a special menu with options like BIOS Setup, Boot Menu, System Recovery, and Normal Startup.
Locating Specific Information in Manuals
As the reference suggests, for the most accurate information specific to your model, you should consult the Hardware Maintenance Manual or the user guide for your Lenovo product.
You can find these manuals on the Lenovo Support website. Searching for your specific model name will allow you to access documentation detailing startup keys and procedures.
Step-by-Step Access (Common Method)
To attempt to access the BIOS using the most common method:
- Shut down your Lenovo computer completely.
- Press the power button to turn it on.
- Immediately and repeatedly press the F2 key (or Fn+F2 if required) as soon as the Lenovo logo appears on the screen.
- Continue pressing the key until the BIOS or UEFI setup utility screen appears.
If this doesn't work, try using the Novo button (if available on your device) or consult your specific model's manual.
