Without stamina. With the V510-15IKB, Lenovo offers a quiet 15.6-inch device for work. It is well equipped: Among others, it comes with a Kaby Lake processor, an SSD, Windows 10 Pro, and an IPS display. However, the battery runtimes are disappointing.

The flex on the right side of the keyboard — around the Enter key and the numeric keypad — is actually quite terrible and annoying. Overall, the keyboard is pretty 'meh'. I'm losing trust in your reviews, Notebookcheck.
