HP ProBook 440 G6 charging issue

@n0-name .

Apparently this type of abnormal occurrence so to speak has occurred in other equipment as reported by other users.

Thanks for the information about the same problem that you have and thanks for paying attention that this problem was happened to you after upgrading BIOS to the 01.17 version. But I have not noticed such a problem with my notebook running on the 01.17 BIOS release, Or maybe i have missed this update and jumped from 01.16 to the current 01.18 release.

Ok, let's downgrade our BIOS.

Battery was charged to the 100% as the Windows power manager reported.

Downgraded to the 01.17 version - nothing happened.

Downgraded to the 01.16 version - Gotcha!  Now it tells that the battery level is 80% and it is not charging. I am quiet sure that during the update process it cannot loose 20% charge. So this bug is related to the reported level, not the fact charge level or so.

So I am staying at the 01.16 version and *maybe* HP will fix that issue in future releases.

The bad thing that i am not able to contact HP support in any way. So maybe the developers will not ever pay attention to this bug.

Upd 28.01.2022 11:05 MSK (GMT+3): 01.19.00 Rev.A BIOS was released yesterday (27 Jan 2022)

The bug mentioned above was still not fixed. Looking at the release notes, only security vulnerabilities was fixed and nothing more.

Hi, thanks for info. I noticed this issue with update 1.17 for sure, but I have different laptop. BIOS 1.17 installed on my laptop on 6. of January 2022 and that's the point where I noticed this issue for the first time. I verified installation based on Windows Update to be 100% sure.

Looking at the 440 G6 01.17.00 Rev.A release notes, it was said that "Updates the battery capacity icon display when Maximize My Battery Health is set in the F10 settings and the battery is fully charged." At the same time, there is no phrase about "80%" level in the 'Battery Health Manager'  BIOS menu while selecting 'Maximize My Battery Health'. It mentioned only in the 01.16 release and older (cannot provide screenshot, i am lazy to downgrade it again and reboot).

So if I understand right, from the 01.17 BIOS release, the Windows will report that the battery is 100% charged, but in fact it is only about 80%. Maybe some users was reported that their battery takes only 80% charge and claimed that it needs to be replaced. It is only my suggestion. This is kind of crapware that HP developers wants to deliver to us, and the only way is not buying HP products or downgrading BIOS with possible security vulnerabilities.

I am glad this worked out for you.  I did not suggest that you downgrade your bios as possibly things can go wrong and most motherboards have soldered on bios.

I suspect the problem with PM is the attempt by the moderators to limit spam. I am guessing that a new member cannot send personal messages unless they have contributed to the discussion.   COVID effects probably caused layoffs of actual HP support personal compounding this problem.

I have surface pro 4 that has only %50 charge option.  That was added as a new bios feature shortly have Microsoft service replaced my battery.  I tried it once and disabled it as %50 does not leave enough of a charge.  If you think you have a battery problem, try a DIY replacement of the SP4 battery!  I managed to replace the battery and get my SP4 working, but the screen, antenna and microphone all were damaged.  The repairability index of HP systems are up in the 8 and 9 rating.  My surface pro is near 0 and for DIY a rating of negative is more appropriate.  I will never buy a system with low repairability again.

Now that your system seems to be charging correctly, can your run that battery report and see if it is calculated correctly?  I would appreciate it if you could post it (where I could download it) for a study that might be helpful to others.

Regards!

There is no new information in the powercfg report. And there Is NO problem with the battery health. My notebook is about 1 year old, and was used rarely.

And from this report i see that battery charge level has instantly changed from 80 to 100%  (finally i've flashed the latest BIOS, because BIOS possible vulnerabilities is more critical for me, rather than the battery).

10:10:38	Active	AC	79 %	mWh
10:10:38	Suspended		79 %	mWh
10:14:49	Active	AC	80 %	mWh
10:20:00	Suspended		80 %	mWh
10:22:06	Active	AC	80 %	mWh
10:34:00	Suspended		80 %	mWh
10:35:27	Active	AC	80 %	mWh
10:41:00	Suspended		80 %	mWh
10:44:24	Active	AC	80 %	mWh
11:02:00	Suspended		80 %	mWh
11:11:06	Active	AC	100 %	mWh
11:30:00	Suspended		100 %	mWh
11:31:10	Active	AC	100 %	mWh
11:31:10	Suspended		100 %	mWh
11:36:59	Active	AC	100 %	mWh
12:30:37	Active	Battery	100 %	mWh
12:31:01	Active	AC	100 %	mWh
13:41:52	Active	Battery	100 %	mWh
13:41:59	Active	AC	100 %	mWh

As you can see, the battery cannot get instant 20% charge in 10 minutes interval, using 40W charger - this is simply impossible.

I guess that there is no problem with the battery or the charger. HP designed a new battery indication behaviour after the 01.16 BIOS release. So when I choose "Maximize My Battery Health" in the BIOS menu, the OS reports that the battery is charged to 100%. But in fact it is only 80%. So the estimated power available is re-calculated to reflect the 100% charge.

I'd rather prefer to turn off this feature so that BIOS displays the actual percentile, not 'virtual' or re-calculated.

Maybe I'm wrong. I don't think that this feature with the battery level report will be changed in furure BIOS releases. Why? Just because true-and-prowd HP engineers just decided that it will be better for us all.

Apple learned their lesson when they limited their iPhone charging to force users to upgrade.  I got a very late class action notification about my iphone 7 (or 6?) . I  owned 3 "family" but could not find the receipt to prove I bought them during the suit interval and I suspect the lawyers were the only ones that made any money in any event.

I marked your previous post as helpful and you might do the same for any others in this thread.

Regards!
