Work with speed and comfort

An array of ports and slots means you can get connected to what you need and a spill-resistant keyboard means less stress if an accident happens. Plus, this TÜV Rheinland certified

It verifies that the computer has not been tampered with before booting up and protects your data against external software attacks. The optional fingerprint reader with Windows Hello allows you to easily and securely log in with just one touch.
