Update BIOS and chipset driver
Updating your BIOS and chipset driver is crucial for ensuring optimal system performance and security. Here's a detailed guide on how to update your BIOS and chipset driver on a Dell Windows 10 computer:
Update BIOS
Before initiating the BIOS update process, it is essential to take some precautionary measures:
- Ensure that your Dell laptop's battery is charged to at least 10%. Dell recommends connecting the laptop to AC power before proceeding.
- Back up your important data. BIOS updates can sometimes result in data loss or corruption, so it's better to be safe than sorry.
- Disconnect external devices such as USB drives, printers, and scanners.
- If BitLocker is enabled, be sure to disable it temporarily to avoid issues with the BitLocker key during the update.
Now, let's move on to the update process:
- Identify the current BIOS version on your Dell computer. To do this, restart your computer and press the F2 key at the Dell logo screen during startup. Look for the BIOS Version under the Main or System Information tab.
- Visit the Dell Support website at https://www.dell.com/support/drivers to download and install the latest BIOS update for your specific Dell computer model.
- Follow the on-screen instructions to complete the BIOS update. Do not turn off your computer during this process.
Update Chipset Driver
Updating your chipset driver is equally important as it helps ensure that your hardware devices work correctly with the operating system:
- Open the Dell Support Drivers website.
- You can choose to let Dell automatically find driver updates for you by clicking "Check for Updates." Alternatively, you can manually search for the chipset driver by entering "Chipset" in the keyword search box.
- Select the operating system installed on your Dell computer and choose the appropriate driver category.
- Toggle on "Show downloads for only THIS PC" to view drivers specific to your Dell computer.
- Download the chipset driver by clicking the "Download" button next to the driver.
- Double-click on the downloaded .exe driver installation file and follow the on-screen instructions to complete the installation.
It's important to note that while installing the chipset drivers, you may encounter an error message stating that the driver is not compatible, not required, or already updated. In such cases, you can ignore the error message and proceed with installing the remaining drivers under the chipset category.

Enable USB Wake Support
To enable USB Wake Support on a Dell computer, you will need to access the BIOS (Basic Input/Output System) settings. The BIOS is a set of built-in instructions that determine how your computer communicates with its hardware components.
- Power on your Dell computer and immediately press F2. You need to be quick as Windows 10 loads quickly, so the time you have to press F2 is short. If you miss the opportunity and it goes to the desktop, restart from the Windows Start button and try again.
- Once you are in the BIOS setup, look for the "USB Wake Support (S3)" option. This option is usually found under Advanced Power settings.
- If you find the "USB Wake Support (S3)" option, ensure that it is enabled. By default, this option is often disabled.
- Save the changes before exiting the BIOS setup.
- If you cannot find the "USB Wake Support" option in the BIOS setup, there is an alternative method. Open the Device Manager on your computer.
- In the Device Manager, expand the list under USB by clicking on it.
- Double-click on a USB root hub and click on its Power Management tab.
- Additionally, expand the list under "Human Interface Devices" and uncheck the same box for any HID entry with a Power Management tab.
