Troubleshooting a Dell Ultrabook that won't wake up from sleep mode
If your Dell Ultrabook won't wake up from sleep mode, there are several troubleshooting steps you can take to resolve the issue. Here are some detailed instructions to guide you through the process:
Step 1: Basic Checks
First, try the simple methods to wake your Ultrabook from sleep. Move your mouse, press any key on the keyboard, or press the power button. If your Dell Ultrabook has been in sleep mode for an extended period, it might have entered hibernation mode, so press the power button to wake it up.
Step 2: Check Power Settings
Ensure that your power settings are correctly configured. Go to Start > Settings > System > Power & Battery > Screen and Sleep. Adjust the settings for how long the device waits before turning off the screen and entering sleep mode.
Step 3: Update BIOS and Chipset Driver
If basic checks don't work, the issue might be related to outdated or incorrect settings. Update your BIOS and chipset driver. Before updating BIOS, ensure that BitLocker is suspended if it's enabled on your Ultrabook.
Step 4: Enable USB Wake Support
In the BIOS settings, enable "USB Wake Support." This allows the Ultrabook to wake up when a USB device is connected or used.
Step 5: Run Windows Power Troubleshooter
Run the Windows Power Troubleshooter to adjust your power settings and check for any issues. Go to Control Panel, type "Troubleshooting" in the search field, click "Troubleshooting," then "Improve Power Usage" under "System and Security." Run the Power Troubleshooter and test if the issue is resolved.
Step 6: Update Video Driver
If the issue persists, update your video driver. Some Dell Ultrabooks may have two video drivers that need to be updated, including the Intel Integrated driver.
Step 7: Reinstall Operating System
If none of the above steps work, you may need to reinstall your operating system. Before doing so, back up your data and create Windows recovery media.
If you're still encountering problems after following these steps, contact Dell Technical Support for further assistance.

Updating BIOS and chipset drivers
Updating your BIOS and chipset drivers is an essential step in improving your Dell Ultrabook's performance, security, and stability. Here is a detailed guide on how to update your BIOS and chipset drivers:
Step 1: Identify Your Dell Ultrabook Model
Before updating your BIOS, it is crucial to identify your specific Dell Ultrabook model. This step ensures that you download the correct BIOS version for your device. You can identify your Dell Ultrabook by using the automated option with SupportAssist or by manually entering the Service Tag, Express Service Code, or Serial Number.
Step 2: Download the Correct BIOS Update
Visit the Dell Support website (https://www.dell.com/support/drivers) to download the BIOS update for your identified Dell Ultrabook model. Follow the on-screen instructions to install Dell SupportAssist, which will help you throughout this process.
Step 3: Prepare Your Ultrabook for the BIOS Update
Before proceeding with the BIOS update, there are a few important preparations to ensure a smooth process:
- Back up your data: Always back up your important data before performing a BIOS update. In the unlikely event of an error during the update, you can minimize potential data loss by having a recent backup.
- Disconnect peripheral devices: Disconnect any external devices such as USB drives, printers, or scanners. This step helps prevent potential interference during the update process.
- Charge your Ultrabook battery: Ensure that your Dell Ultrabook battery is charged to at least 10% before initiating the BIOS update. It is recommended to connect your Ultrabook to a reliable power source (AC power) to avoid unexpected shutdowns during the update.
- Suspend BitLocker: If you use BitLocker for encryption, temporarily suspend it before updating your BIOS. You can do this by accessing Settings > Privacy and Security Option > Device Encryption > BitLocker Drive Encryption, and then turning off BitLocker.
Step 4: Install the BIOS Update
Once your Ultrabook is prepared, you can proceed with the BIOS update:
- Compare BIOS versions: Check the BIOS version currently installed on your Ultrabook by opening the Start menu, typing "MSINFO32," and looking for the BIOS version date. Compare this with the latest version available on the Dell Support website.
- Download and save the BIOS update file: After confirming that a newer BIOS version is available, download and save the file to your computer.
- Run the BIOS update: Double-click on the downloaded BIOS setup file and confirm the action. Follow any on-screen instructions, and your Ultrabook may restart automatically during this process.
Step 5: Update Chipset Drivers
After updating your BIOS, it is important to update your chipset drivers. Outdated or corrupt chipset drivers can cause issues with your Ultrabook's performance and compatibility. Visit the Dell Support website again to download and install the latest chipset drivers for your specific Dell Ultrabook model.
By following these steps, you can ensure that your Dell Ultrabook's BIOS and chipset drivers are up to date, optimizing its performance, security, and stability.

Enabling USB Wake Support
To enable USB Wake Support on a Dell Ultrabook, follow these steps:
- Reboot your Dell Ultrabook and immediately press F2 to access the BIOS setup menu. The steps to access the BIOS setup menu may vary depending on your specific Dell model, so refer to your product manual or Dell support resources if needed.
- In the BIOS setup menu, look for the "USB Wake Support" option. This option may be found under "Advanced Power Settings" or a similar category.
- Ensure that the "USB Wake Support" option is enabled. If it is not already enabled, use your keyboard to navigate to the option and press the appropriate key to enable it. The key you need to press will be indicated in the BIOS setup menu, but it is typically something like F5 or Enter.
- Once USB Wake Support is enabled, save your changes and exit the BIOS setup menu. This can usually be done by pressing the F10 key or selecting the appropriate option with your keyboard.
- If enabling USB Wake Support in the BIOS does not resolve the issue, you may need to make additional changes in your operating system's device settings. For example, in Windows, open the Device Manager and ensure that the Power Management settings for your USB devices are properly configured to allow them to wake the computer.
- After making any necessary changes, test your Dell Ultrabook to ensure that USB devices can now be used to wake it from sleep mode.
Please note that USB Wake Support may not function if your Dell Ultrabook is running on battery power. It is also important to ensure that your USB ports are not in Deep Sleep mode, as this will prevent USB Wake from functioning properly.
