HP EliteBook 820 G4 (Z2V72ET) Notebook
  • One of the fastest SSDs offered for this EliteBook.
  • Great solid state drive from Samsung company with capacity of 512gb.
  • The transfer rates are significantly better than those of SATA III SSDs.

  • The benchmark results of SSD drive are very good and the sequential transfer rates in particular are superior to SATA-III drives.

What customers say about "Features"
HP EliteBook 820 G4 (Z2V72ET) Notebook
  • Since it is a business notebook, the device delivers many security features as a matter of course.
  • It comes with a Trusted Platform Module (2.0). Amazing for some security.
  • There is a smartcard reader as well as a fingerprint reader for biometric access control. In addition, HP's security software is pre-installed.
  • The smooth keys feature a short travel and a crisp pressure point. It's a joy to type on this keyboard.
  • The web cam produces images with a maximum resolution of 1280x720 pixels. It is obvious that the images lack sharpness.
HP EliteBook 840 G4 (2TM97ES) Laptop
  • HP implements numerous software tools and features to increase the security of the laptop.
  • Well protected device with fingerprint scanner (swipe-style), TPM, SmartCard reader, and a slot for a Kensington lock.
  • Very satisfied with the keyboard and even longer texts are no problem.
  • It is unfortunately not an IPS screen but is based on TN technology, which was already the case for the previous model and was not the best.
  • The individual keys are completely flat, makes typing uncomfortable.

  • The EliteBook 840 G3 was equipped with a modern USB-C jack.
  • Happy, that it has both, DisplayPort and VGA ports.
  • DP and VGA connectors are very important for office environments.
  • Type-C is still just a "regular" USB 3.1 port without support for Thunderbolt, DisplayPort, or power supply.
  • The port layout is not perfect, because they are at the center of the two sides.
