There are a lot of "Zbook 15 G2" workstation models in this series.


In General:

The model series was introduced early to mid 2015, with at least one model being introduced at the end of that calendar year.


If the battery is the original to the workstation, that is, the original battery is installed in the computer, that battery may need to be replaced.


You can test and / or calibrate the battery.

You can test the AC adapter.

Battery having trouble?

  • If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down. Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.
  • The battery might be OK and just need calibration (balance / set).


The steps to check / calibrate / replace the battery are included in this document:
