When AC adapter is plugged-in, laprtop dischares

[Nikolay_K]

On my laptop HP Zbook 15 G3, I have charging probem, which appears time to time.

Sometimes when I plug in AC adaptor, after few minutes I notice that laptop does not charge. Sometimes works normally.

I already tryied followings:

1. Buy new oroiginal AC adaptor. No change.

2. If switch off laptop, disconnect apdtor and connect to the laptop again after few minutes, nothig happens. Also not charging even in off-state.

Only 1 things help me: Switch off laptop. Reset by pressing 30 sec of power button and switch on again. In this case laptop start charging.

But it very disappoints me, because I must again restart all working aplication, which was started before, and it takes a time.

Who know, what can be a problem?
