HP Aero 13.3 Battery Drain

[Francko]

On my HP Pavillion Aero 13.3" from the time I bought it I noticed that the battery drains when the laptop is shutdown by about 2 to 3% a day.

I've tried some software troubleshooting I found online, which only slightly helped and the problem still persist.

Please support.

Merry Christmas, @Francko ,

All batteries lose some storage capacity when not in use and the  percentage of storage capacity loss  is relative to the temperature.

It is just the normal  physics of battery technology.

Battery drain in the range of 2 to 3% per day is not normal at all! Modern Li-Ion batteries have a drain of 0.5 to max. 3% per MONTH! So obviously, there is a problem either with the battery or with other hardware parts or the Bios in this laptop. In another thread with the same topic somebody mentioned that he replaced the Wifi module and as a side-effect the battery drain was significantly reduced. So, HP Support: What solution do you have to offer?

Hi @Flyfox 

A Lithium Ion battery  have a drain of " 0.5 to max. 3% per MONTH!" is only if it is not used.

How does that work out for your mobile phone? 
You do know it has a Lithium Ion battery, right?

Thanks, Erico, for your fast reply! You might have overlooked that this thread is about the battery drain, when the laptop is powered OFF. Of course, if I put it into standby mode (power save mode), the battery drain is in the range of up to a few percent per day, as parts of the electronic circuit (mainly the RAM) require some electric power to keep its data. This of course is also true for every smartphone. But if you power down the product completely, the battery drain should be almost negligible, as it is only a factor of the battery. Modern Li-Ion batteries have a very small self-discharge as mentioned above. E.g. my 8-year-old iPhone (which I still use as a backup ocasionally), keeps its charge for months with a drain of less than 3% per month!

My problem with this laptop appeared for the first time when I left it powered OFF for a couple months due to a long absence. On my return, the battery was completely empty, which, as you certainly know, is very bad for the battery life. So obviously, there is a problem with the power OFF battery drain here.

It is interesting that you hijacked a thread. 

The electronics in a laptop the needs current, whether it is on or off is NVMe memory and the BIOS, which is a CMOS chip.

If you believe that a laptop, without a new battery would still have much battery storage left after storing it for months, your expectations are unfortunately, unrealistic.

Take a read of all laptop manufacturer forums, there are many, and you will see that the battery complaints are consistently the same.  Until the battery chemistry changes that will remain the same. 

There are new battery types on the horizon. 

All we can do is hope for improvement, in terms of greater capacity, smaller size and less storage capacity drain over time.

 Don't believe all of the marketing material that is available.

Hijacked the thread? Are you serious? Would you mind reading the first post again carefully? I have exactly the same problem as described in the first post. But your reply was not satisfying. What else should I have done? Open a new thread with exactly the same question?

Why do you mix up two completely independent effects on battery drain? On one side you are talking about electronic circuits which consume current while powered OFF. A nonvolatile memory like an SSD does not consume the slightest amount of electric energy while being powered off. They are called nonvolatile because they keep their information regardless of the power status. The BIOS is a firmware stored on a CMOS chip, which mostly keeps its data with battery power, when the computer is shut-off. Its current consumption is extremely small and would by no means drain the battery by 2 to 3% per day.

The battery technology is a completely different story. As mentioned before, a good Li-Ion battery has a self-discharge rate of less than 3% per month. Lower quality units may be in the range of up to  5%. I expect the battery in the Aero 13 to be a high-quality product, but even with a self-discharge rate of 5 or 6% per month, it would not really be a problem.

My conclusion: There must be some hardware in this laptop which is not completely powered off after powering the laptop OFF (e.g. the Wifi adapter). This might be caused by lacking circuit-design, faulty hardware components or some software drivers. Only HP knows the real reason, but HP‘s support seems to prefer leaving the customers out in the rain …

Regarding my believes: I have worked as an electronics engineer for over 30 years, and I think i know what I am talking about.

PS: Sorry for my long post, but it really seemed necessary to put a few thing right.

It is interesting, Erico, that you now seem to hide yourself behind a curtain of silence, after repeating untrue statements from questionable sources rather than providing useful support for your products. Very disappointing.

If you had authored the thread you would not be a hijacker. 

Hijacking a thread means taking over the conversation of a thread started and authored by another individual. 

It is unfortunate, but that is what you have done. 

"What else should I have done? Open a new thread with exactly the same question?"

If you look in this and other forums, you will see that is what others  do. Even if you search and find an identical issue that has been archived, a new thread is the solution.

I do agree that the SSD would not be the culprit in the drain. I was wrong about that. There is something else that is causing it, possible even a battery that has issues. Perhaps whatever component on the system board  that has an issue could be found by using an IR camera.

Come on, Erico, this is complete nonsense. Everybody is invited to join a thread with questions, answers or proposal regarding the initial topic of the thread. Going OFF-TOPIC is not nice and considered hijacking the thread. Have a look here: https://www.urbandictionary.com/define.php?term=Thread%20Hijacking or here: https://en.scratch-wiki.info/wiki/Thread_Hijacking

I would really appreciate if this support forum would try to provide real help (have you contacted your laptop technical department regarding this problem?) rather than defending product weaknesses and untrue statements. But maybe my expectations of an over 50k-posts-support person was simply too high …
