by ·Comments Off on Important Windows Update: Preventing Overheating, Battery Drain, and Unexpected Crashes On Your Computers

ITS has identified an issue resulting in HP Windows laptops overheating, battery drain, and experiencing unexpected crashes. We’re making a small but important change on Thursday, October 30th, 2025, to how your Windows laptop manages power when it’s running on battery with the lid closed.

This update is designed to prevent overheating, battery drain, and unexpected crashes that some users have experienced, especially when the laptop is left undocked.

Action

Please reboot your device after October 30th to ensure all changes and settings are fully applied.

What’s Changing?

When your laptop is unplugged and the lid is closed for more than 10 minutes, it will now enter hibernate mode instead of sleep. Hibernate mode fully powers down the device while saving your work, which helps:

  • Stop overheating and fan noise
  • Preserve battery life
  • Prevent crashes and data loss

What You’ll Notice

If your laptop hibernates:

  • You will need to press the power button to wake it.
  • You will be asked to enter your BitLocker key, just like after a reboot.
  • Your session will be restored exactly as it was – no lost work.

If the lid is closed for less than 10 minutes, it will wake up normally without needing the power button or BitLocker key.

Why This Matters

This change has already helped several users avoid issues with their laptops. It’s a simple adjustment that makes a big difference in reliability and battery performance.

Can I Change This Setting?

While we do not recommend that you change this setting, you will be able to adjust it if this does not fit your workflow through the power settings of your device by following the instructions here.

Thank you for your understanding and support as we work to improve your experience. 

Questions?

If you have any questions or concerns, please reach out to the ITS Service Desk at 740-587-6395 or email servicedesk@denison.edu.

by ·Comments Off on Duo Update Coming Monday, March 23rd

Over the past three months, 25 Denison accounts were taken over through phishing attacks that tricked people into approving a fraudulent Duo request. While these attacks have not yet led to data loss, this type of attack increases the risk that sensitive information and systems could be compromised.

Starting on Monday, March 23rd, a real-time security check will be added to the Duo login process to detect unusual login activity. If a login appears unusual, such as logging in from a new device and/or location, less-secure verification methods will not be available. 

What you’ll see

  • For the vast majority of logins, your login experience will remain unchanged. When using Duo Push, you’ll only need to enter a 3-digit code.
  • If an unusual login is detected, a high-security authentication method is required.
    • Less-secure Duo options, including phone calls and text messages, will be unavailable.
    • Duo Push will require a 6-digit code.
  • If you receive a Duo verification request that you did not initiate, deny it and change your Denison password immediately to protect your account.

What do you need to do?

  • If you already use Duo Push: You’re all set! No action is required.
  • If you primarily use Duo phone calls or text messages: Make sure you have a high-security authentication method set up so you can always log in to your Denison account. High-security authentication options include:
    • Duo Push
    • Built-in Device Authenticators such as Apple Touch ID, Face ID, or Windows Hello
    • YubiKey series 4/5 tokens

To learn more about Duo, visit my.denison.edu/duo

  • For a list of Duo authentication options, see: “Which Duo MFA authentication method is right for you?”
  • To add or update your Duo authentication methods, see: “How Do I Manage My Duo Devices?”

If you have any questions, please contact the Service Desk at (740) 587-6395 or servicedesk@denison.edu.
