ESD problem / very strange engineering of Omen 2017 - 15

HP Recommended
OMEN by HP Laptop 15-ce0xx
Microsoft Windows 10 (64-bit)

Dear HP.

 

I am amused with beeing first-time HP customer. I like Omen 15 2017 with GTX 1060, really. 

Most of thi things are fine.

Yes it does not resume from sleep etc, as usual for new notebooks, but it will be sorted out soon as drivers arise, that's for sure.

 

BUT, I have a SERIOUS question, just for my curiosity and for people who may face the same issue again.

 

Your Omen 15 does have alluminium top keyboard cover which is not connected to motherboard ground. This is probably due to ESD regulations as HP treats them, according to https://support.hp.com/rs-en/document/c02807128 you are trying to reduce or eliminate "Tingle current" issue.

By default, from A to Z, form Apple to ASUS 🙂 (sorry no Z, but you have the idea), any metallic plate is grounded to MB zero. MB zero in turn is averaged to mid-outlet level (because no real ground exists).

HP DOES NOT do this.

In effect we see that ESD discharge DOES NOT go to some PROPER path, but discharges randomly into notebook internals where it is not expected.

 

Please check my great video - I did it 10 times in a row. Discharge turns it off.

There are many more reports on your forums about it. It can be repeated 10 out of 10 times, we have ESD-friendly place here. Not a issue for ANY notebook except HP.

The solution is simple - to redo the grounding as displayed here. sorry HP for this cruelty.

However this saves from ESD turns off issue and now I can do it 100 times in a row without any problems. I have found no point to go for warranty etc, because I found no single trace that this plate should be grounded by your design.

It seems that you stay it floating with the effect above in the video.

The other people having the same issue with any latest HP notebook, according to the forums, confirms it.

 

That is not a support question actually. That is just a warning for some next people and wide-open-eyes question to your electrical engeneers on how had you managed to get to this design.

Does the metal plate REALLY supposet to be let floating and no connection to the ground? With any ESD as a consequence killing the notebook runtime?

Really?

 

Thanks for your attention, happy (no joking) HP customer. 🙂

HP Omen 2017 static discharge - turns off. Metal plate is not connected to motherboard ground, and discharges randomly in the inner circuits. Instant turn of...
