Update the BIOS and chipset driver
Updating the BIOS and chipset driver on your Dell laptop can help keep the system software current and compatible with other computer modules. It also provides security updates and increased stability. Dell typically releases software updates for BIOS, drivers, firmware, and other software components for laptops on the second Tuesday of every month.
Before updating your BIOS, it is important to back up your data as errors during the update may result in potential data loss. Disconnect devices such as external USB drives, printers, and scanners. Ensure your Dell laptop battery is charged to at least 10% and that the laptop is plugged into a reliable power source before proceeding with the update.
To update your Dell laptop's BIOS, first, identify your Dell computer model. You can do this by going to Dell.com/support and using the automated option, SupportAssist, to detect your computer. Alternatively, you can manually enter the Service Tag, Express Service Code, or the Serial number of your Dell computer.
Next, download and install the latest BIOS update. Go to the Drivers and Downloads section, set BIOS as the Category, and download the latest update. Browse to the location where the downloaded file was saved, double-click the file, and follow the on-screen instructions to complete the installation process.
If you are using BitLocker for encryption, you will need to temporarily suspend BitLocker before updating the BIOS. To do this, use the Windows Start button to access settings, click on the Privacy and Security Option, then on Device Encryption, and follow the prompts to turn off BitLocker.
Finally, remember to install each BIOS update individually and in order from the oldest to the newest. The system will restart each time as part of the update process, so be sure to save your work beforehand.
