Smart Charging for HP Pavilion x360 15 Convertible PC

[BobEbaugh]

Just added a large external monitor via USB C.   It also functions as a battery charger.   I need to implement the Windows 11 Smart Charging feature.

Use Smart charging in Windows - Microsoft Support

Microsoft says to look at manufacturer website.   Unable to find for Pavilion series.  But it's probably the equal of this utility for Business notebooks:

This feature is not "on" and I want to turn it on.   Where is the utility or instructions for implementing in BIOS?

Hi @BobEbaugh,

Thank you for your response, 

Due to limited support, I would request you contact our HP Support and our Support Engineers should be able to sort this out. HP Support can be reached by clicking on the following link.

Hi @Alden4

Since I wrote the original post, I have spent several hours on this particular question, including opening a case with HP Support.   Is there any way to view the specifics of the case?   All I can see is it's still open.

For what it's worth, on this particular issue, no one really wants to answer the question.   Chat support indicated they were not trained to answer it, and directed me to an outside but affiliated support group that charges for phone support.   Both here and the Facebook Messenger group provided the same generic answer, contact support.   

I've done much research on this issue.   Most major notebooks have a utility similar to the HP one I mentioned in the original post.   It appears that HP has only implemented this so far in their "business" notebooks.   What is implemented is a feature called "Adaptive Battery Optimizer".   See:

https://support.hp.com/us-en/document/c06310986

That document, seems to be the most complete write-up on this feature available.   It notes " battery run time may be slightly reduced" if the feature is enabled.    That implies there is some charge limiting taking place.   But the algorithm used and what else this option might do, doesn't appear to be documented.   Some unofficial comments on Reddit suggest it does automatically limit charging over time by still reporting 100% charge to Windows, when the actual state of charge is less.

I would be terrific if HP support could comment on this issue by providing more clarity on the adaptive battery optimizer does, and how to see what the actual battery state of charge is, if it's different than what Windows reports.

Thanks, Bob

HP support had me run UEFI diagnostics on just the the battery.    The battery details shown there indicate that the Full Charge capacity of the battery is reduced.   41 vs 43 WHr.    And that the charge capacity is 94% of new/design values.  Thus being regulated short of absolute full charge.

Support indicated that this is due to the "Adaptive Battery Optimizer".  This is the consumer implementation of "Smart Charging".   I'm gonna go with this for now and close this thread.   It makes sense.

Comments:

1) I'd really like to see a more controllable option, like on the commercial/business laptops.   

2) The other way to read the UEFI diagnostic is that the battery is only capable of meeting 94% of its design capacity.   Due to age/use.   If anyone is really interested, turn OFF the adaptive optimizer setting, go through a couple battery cycles and see what the utility reports then.   I'm moving on for now.
