All University staff laptops are protected using BitLocker Technology. BitLocker is a disk encryption technology which protects the disk from being read if it is stolen.

How BitLocker works

When powering on a laptop protected by BitLocker you will be prompted to enter your PIN. The PIN is set on every laptop, so any valid users of the laptop must have access to the PIN.

Once the pin has been entered the data on the laptop is no longer protected by BitLocker. When leaving or transporting a laptop it should either be hibernated or powered off as this ensures the PIN must be entered again to regain access.

Standby Mode

Laptops will be able to hibernate but standby mode is disabled. This is because a laptop on standby does not require entry of the PIN. Allowing the laptop to enter standby represents a security risk.

Set your PIN

When a University staff laptop is issued you must set your PIN. This PIN will be required whenever the laptop is powered on. The PIN is always entered using the numeric keys on the Laptop keyboard. The function keys are the same on all keyboards, regardless of layout or language.

Your PIN should never be stored with the laptop computer.

Will Bitlocker effect performance of my laptop?

The performance implication of encrypting your laptop system disk with BitLocker technology is minimal. Microsoft suggests that the overhead is around 3-5% on a modern laptop.

What if I forget my PIN?

If you forget your PIN the data on the laptop can be recovered. Authorised members of IT Services staff have access to a recovery key which can be used to decrypt the disk. Contact the IT Service Desk in the event you have forgotten you PIN, you may need to bring your laptop to the End User Support team.

Remove BitLocker protection

You cannot remove BitLocker protection from your University staff laptop. In the event that your laptop must be decrypted contact the IT Service Desk. Once decrypted your laptop must be returned to a safe and secure location. It must not be taken off site.
