+ | ==== Determining the BIOS version ==== | ||
+ | |||
+ | The BIOS version is usually displayed quickly when a computer is booting, and when [[other:bios#entering_the_bios|you are in the BIOS options screen]] | ||
+ | |||
+ | You can also get the BIOS version when your operating system is running! | ||
+ | |||
+ | === From Windows === | ||
+ | |||
+ | Use the [[https://support.microsoft.com/en-us/topic/description-of-microsoft-system-information-msinfo32-exe-tool-10d335d8-5834-90b4-8452-42c58e61f9fc|msinfo32]] command (i.e. type ''msinfo32'' in the search field at the bottom left of the screen, and then launch the System Information app) and check the //BIOS version// line in the //system summary// screen. You will also get lots of other useful information about your computer (e.g. computer name) | ||
+ | |||
+ | === From Linux === | ||
+ | |||
+ | Use the [[http://manpages.ubuntu.com/manpages/xenial/man8/dmidecode.8.html|dmidecode]] command: ''dmidecode -s bios-version'' | ||
+ | |||
+ | <code>$ sudo dmidecode -s bios-version | ||

+ | ==== Updating the BIOS ==== | ||
+ | |||
+ | <WRAP center round important 60%> | ||
+ | Updating the BIOS is safe, but it may be a good idea to get help from somebody who has already done it. Your computer may restart several times, blink, etc, before the update is complete. | ||
+ | |||
+ | Be sure to be connected to a power supply during the update | ||
+ | |||
+ | If your Windows computer is protected by **bitlocker** at boot time, you have to [[https://www.dell.com/support/kbdoc/en-us/000125409/how-to-enable-or-disable-bitlocker-with-tpm-in-windows#TOC05|suspend bitlocker]] (//suspend//, and **not** //disable//), **before rebooting**. [[https://docs.microsoft.com/en-us/troubleshoot/windows-client/windows-security/suspend-bitlocker-protection-non-microsoft-updates|more info]] | ||
+ | |||
+ | The BIOS update will take place during the boot time, then Windows will start and bitlocker will automatically start again </WRAP> | ||
