Software

This chapter details the supported operating systems along with instructions on how to install the drivers.

Topics:

- Downloading Windows drivers

Downloading Windows drivers

1. Turn on the notebook.
2. Go to Dell.com/support.
3. Click Product Support, enter the Service Tag of your notebook, and then click Submit.

NOTE: If you do not have the Service Tag, use the auto detect feature or manually browse for your notebook model.

1. Click Drivers and Downloads.
2. Select the operating system installed on your notebook.
3. Scroll down the page and select the driver to install.
4. Click Download File to download the driver for your notebook.
5. After the download is complete, navigate to the folder where you saved the driver file.
6. Double-click the driver file icon and follow the instructions on the screen.

System setup

CAUTION: Unless you are an expert computer user, do not change the settings in the BIOS Setup program. Certain changes can make your computer work incorrectly.

NOTE: Before you change BIOS Setup program, it is recommended that you write down the BIOS Setup program screen information for future reference.

Use the BIOS Setup program for the following purposes:

• Get information about the hardware installed in your computer, such as the amount of RAM and the size of the hard drive.
• Change the system configuration information.
• Set or change a user-selectable option, such as the user password, type of hard drive installed, and enabling or disabling base devices.

Topics:

• Boot menu
• Navigation keys
• Boot Sequence
• BIOS setup
• Updating the BIOS in Windows
• System and setup password

Boot menu

Press when the Dell logo appears to initiate a one-time boot menu with a list of the valid boot devices for the system. Diagnostics and BIOS Setup options are also included in this menu. The devices that are listed on the boot menu depend on the bootable devices in the system. This menu is useful when you are attempting to boot to a particular device or to bring up the diagnostics for the system. Using the boot menu does not make any changes to the boot order stored in the BIOS.

The options are:

- UEFI Boot Devices:

• Windows Boot Manager
  oUEFI Hard Drive
  ○Onboard NIC (IPV4)
  ○Onboard NIC (IPV6)

- Pre-Boot Tasks:

oBIOS Setup
o Diagnostics
oBIOS Update
○SupportAssist OS Recovery
- BIOS Flash Update - Remote
○Device Configuration

Navigation keys

NOTE: For most of the System Setup options, changes that you make are recorded but do not take effect until you restart the system.

Keys Navigation

Up arrow Moves to the previous field.

Down arrow Moves to the next field.

Enter Selects a value in the selected field (if applicable) or follow the link in the field.

Spacebar Expands or collapses a drop-down list, if applicable.

Tab Moves to the next focus area.

Esc

Moves to the previous page until you view the main screen. Pressing Esc in the main screen displays a message that prompts you to save any unsaved changes and restarts the system.

Boot Sequence

Boot sequence enables you to bypass the System Setup-defined boot device order and boot directly to a specific device (for example: optical drive or hard drive). During the Power-on Self-Test (POST), when the Dell logo appears, you can:

• Access System Setup by pressing F2 key
• Bring up the one-time boot menu by pressing F12 key.

The one-time boot menu displays the devices that you can boot from including the diagnostic option. The boot menu options are:

●Removable Drive (if available)
- STXXXX Drive

NOTE: XXXX denotes the SATA drive number.

●Optical Drive (if available)
●SATA Hard Drive (if available)
• Diagnostics

NOTE: Choosing Diagnostics, displays the SupportAssist diagnostics screen.

The boot sequence screen also displays the option to access the System Setup screen.

Updating the BIOS in Windows

It is recommended to update your BIOS (System Setup) when you replace the system board or if an update is available. For laptops, ensure that your computer battery is fully charged and connected to a power before initiating a BIOS update.

NOTE: If BitLocker is enabled, it must be suspended prior to updating the system BIOS, and then re enabled after the BIOS update is completed.

For more information about this subject, see Knowledge Article: How to Enable or Disable BitLocker with TPM in Windows.

6. Choose the Products category from the list.

NOTE: Choose the appropriate category to reach the product page.

1. Select your computer model and the Product Support page of your computer appears.
2. Click Get drivers and click Drivers and Downloads.

The Drivers and Downloads section opens.

Updating BIOS on systems with BitLocker enabled

CAUTION: If BitLocker is not suspended before updating the BIOS, the next time you reboot the system it will not recognize the BitLocker key. You will then be prompted to enter the recovery key to progress and the system will ask for this on each reboot. If the recovery key is not known, this can result in data loss or an unnecessary operating system reinstall.

Updating the Dell BIOS in Linux and Ubuntu environments

If you want to update the system BIOS in a Linux environment, such as Ubuntu, see Update the Dell BIOS in a Linux or Ubuntu environment.

Flashing the BIOS from the F12 One-Time boot menu

Updating your system BIOS using a BIOS update .exe file that is copied to a FAT32 USB drive and booting from the F12 one time boot menu.

BIOS Update

You can run the BIOS update file from Windows using a bootable USB drive or you can also update the BIOS from the F12 One-Time boot menu on the system.

Most Dell systems built after 2012 have this capability and you can confirm by booting your system to the F12 One-Time Boot Menu to see if BIOS UPDATE is listed as a boot option for your system. If the option is listed, then the BIOS supports this BIOS update option.

NOTE: Only systems with BIOS Flash Update option in the F12 One-Time Boot Menu can use this function.

Updating from the One-Time Boot Menu

To update your BIOS from the F12 One-Time boot menu, you need:

• USB drive formatted to the FAT32 file system (key does not have to be bootable).
• BIOS executable file that you downloaded from the Dell Support website and copied to the root of the USB drive.
• AC power adapter that is connected to the system.
  ●Functional system battery to flash the BIOS.

Perform the following steps to run the BIOS update flash process from the F12 menu:

CAUTION: Do not power off the system during the BIOS update process. Powering off the system could make the system fail to boot.

1. From a power off state, insert the USB drive where you copied the flash into a USB port of the system.

2. Power on the system and press the F12 key to access the One-Time Boot Menu.

3. Select BIOS Update using the mouse or arrow keys then press Enter.
