Determining the BIOS version
To determine whether available BIOS updates contain later BIOS versions than those currently installed on the tablet, you need to know the version of the system BIOS currently installed.
BIOS version information (also known as ROM date and System BIOS) can be revealed by pressing fn+esc (if you are already in Windows) or by using Setup Utility (BIOS).
1. Start Setup Utility (BIOS)
2. Tap Main, and then make note of your current BIOS version.
3. To exit Setup Utility (BIOS) without saving your changes, tap Exit, tap Exit Discarding Changes, and then follow the on-screen instructions.
– or –
To start Setup Utility (BIOS) using an optional USB keyboard (purchased separately):
1. Connect an optional USB keyboard (purchased separately) to the tablet.
2. Turn on or restart the tablet, quickly press esc, and then press f10.
BIOS updating
1. From the Start screen, type support, and then select the HP Support Assistant app.
2. Click Updates and tune-ups, and then click Check for HP updates now.
3. Follow the on-screen instructions.
4. At the download area, follow these steps:
a. Identify the most recent BIOS update and compare it to the BIOS version currently installed on your tablet. If the update is more recent than your BIOS, make a note of the date, name, or other identifier. You may need this information to locate the update later, after it has been downloaded to your hard drive.
b. Follow the on-screen instructions to download your selection to the hard drive. If the update is more recent than your BIOS, make a note of the path to the location on your hard drive where the BIOS update is downloaded. You will need to access this path when you are ready to install the update.
BIOS installation procedures vary. Follow any instructions that are revealed on the screen after the download is complete. If no instructions are revealed, follow these steps:
1. From the Start screen, type file, and then select File Explorer.
2. Click your hard drive designation. The hard drive designation is typically Local Disk (C:).
3. Using the hard drive path you recorded earlier, open the folder on your hard drive that contains the update.
4. Double-click the file that has an .exe extension (for example, filename.exe). The BIOS installation begins.
5. Complete the installation by following the on-screen instructions.
