Using the Laptop’s BIOS or UEFI
Accessing the BIOS or UEFI settings is one of the most reliable methods to find your laptop’s serial number. This method is particularly useful if your laptop is not fully operational, as it does not rely on the operating system. The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is a firmware interface that initializes hardware during the booting process and provides runtime services for operating systems and programs.
To access the BIOS or UEFI, follow these general steps, keeping in mind that the exact key to press can vary depending on the laptop brand:
Step 1: Restart Your Laptop
Begin by restarting your laptop. As soon as it starts booting up, you will need to press a specific key to enter the BIOS or UEFI settings. Common keys include F2, F10, F12, Esc, or Del. The correct key is often displayed briefly on the screen during startup.
Step 2: Enter the BIOS/UEFI
Press the appropriate key repeatedly until you enter the BIOS or UEFI setup utility. If you miss the window during the initial boot sequence, restart your laptop and try again.
Step 3: Navigate to System Information
Once inside the BIOS or UEFI, use the arrow keys on your keyboard to navigate through the menus. Look for a section labeled “System Information,” “System Summary,” or similar. This section typically contains comprehensive details about your laptop, including the serial number.
Step 4: Locate the Serial Number
Within the System Information section, find the entry labeled “Serial Number,” “Product Number,” or “Service Tag.” This is your laptop’s unique identifier.
Here are specific key presses for some popular laptop brands:
- Dell: F2 or F12
- HP: Esc or F10
- Lenovo: F1 or Enter + F1
- Asus: F2 or Del
- Acer: F2 or Del
Using the BIOS or UEFI to find your laptop’s serial number is an effective method that works regardless of the laptop’s current operating condition. This ensures that you can retrieve your serial number even if the laptop’s operating system is unresponsive or corrupted.
