Hello
We have some domained HP 840 G3's that keep failing to turn on. After holding the power button for a few seconds they do nothing however if you repeat the process they then all of a sudden come to life with a very brief flash of the power button and then they go off again. If you then repeat THIS process about 2 to 3 more times they eventually turn on completely and function as normal? I figured it may be board related but I am not familiar with this issue. Has anyone experienced this before? I can't think where to start as I wouldn't want to get them replaced if it's a software issue or something else minor.
Specs are:
Win 10
8GB RAM
i5-6300U
Thanks, Adam
