Калибровка аккумулятора ноутбука с помощью BIOS
При длительной эксплуатации ноутбука часто возникают проблемы с его аккумуляторной батареей (АКБ). Ноутбук начинает внезапно отключаться. Происходит это из-за расхождения данных контроллера, следящего за зарядкой-разрядкой аккумулятора, с фактическим состоянием батареи. Ноутбук, получив от него неверные сигналы о полной разрядке АКБ, автоматически выключается.
Для того, чтобы вернуть к жизни ноутбук необходима калибровка батареи. Её задача – обеспечить соответствие показаний передаваемых контроллером, фактическому уровню заряда в аккумуляторе.
Выполняется этот процесс как через BIOS, так и вручную, используя специализированные программы.
Для наглядности приведем простой пример, когда ясно, что пора заняться калибровкой.
Когда калибровка, безусловно, необходима
Например, уровень аккумуляторного заряда – 70%, а контроллер имеет данные про 50%. В этом случае при 10% заряде лэптоп отправляется контроллером в спящий режим. Но, ведь фактически батарея будет заряжена на 30%. Ноутбук вполне мог еще автономно работать. А из-за таких неправильных показаний устройства, его необходимо заряжать. Эту ошибку можно исправлять калибровкой.
Оценка ёмкости и состояния батареи лэптопа
Воспользуйтесь возможностями командной строки:
Если во время последней полной зарядки значение емкости ниже номинальной – пришло время заняться калибровкой.
Ручная калибровка
Проще всего произвести калибровку вручную. Алгоритм действий простой:
Калибровка через BIOS
Важно. Калибруя таким способом, сначала отключийте блок питания. Иначе высветится сообщение с предупреждением от BIOS.
Алгоритм действий незначительно отличается в различных моделях лэптопов. Если взять Phoenix, то это происходит так:
Вот, в общем, и весь секрет. Долгого срока службы вашим батареям и надеемся, инструкция вам не пригодится.

Unknown Battery Remaining?
Hi, I need help with my HP Pavillion 13x360PC I am using Microsoft Windows 10 Home.
My battery icon will randomly say «unkown remaining». Sometimes it will work as normal and state what it’s charge is at and will function fine, unplugged for it’s whole battery life (5 hours). Other times it needs to be plugged in or else it will shut down within minutes (even though it has a full charge), during those times it needs to be plugged in or else it will not turn back on. Then I will turn it back on and it will say it’s 100% charged and work fine.
On startup, I sometimes get a battery alert. I have tried running the battery test from HP Assistant and it will not complete the test with message: «program has stopped working.»
Please help, it’s been happening on and off for a few months now.

Hi, I am not sure if this article is relevant for me. It says it is for laptops that have a removable battery. I am pretty sure my laptop battery is not considered removable.
What should I do now?
Thank you for posting back.
The steps are same for both removable and nonremovable battery.

I used the HP Support Assistant to check my battery. It said that my battery is «OK». However, my laptop is currently functioning «normally» where it says what the battery life is at, and when I plug in my charge cord it says, «plugged in, not charging».
I have to note that I did this same test a few weeks ago when my laptop was in the state where it said «unknown remaining» or when plugged in, «charging, unknown remaining» and when I did this same test it said it was testing for a few moments and then it said, «program has stopped working». I mentioned this in my first post.
What do I do now? Thanks.
Thank you for posting back.
I really appreciate your time and efforts.

I followed your steps around 4pm. It seemed like nothing changed so I restarted my computer. Still seemed like nothing changed so I went about my day working on my computer, watching videos, researching articles, etc. It is 10pm now, I went to watch a video on the same site I had been earlier and in the middle of it the laptop randomly froze and started making this loud, weird (deep?) noise. It was completely frozen nothing I pressed would fix it. I ended up having to hold the power button down to shut it off.
I restarted it and it started fine. I unplugged the charge cord and it shut off immediately (which is worse than before because before it would either take a few minutes or even hours and then randomly shut off but only when it said «unknown remaining». Now it isn’t even saying that anymore but it is just acting worse than before I even asked for help!!
Hoping you can help me, or at least make it go back to before. Thanks.

I recommend you to update the bios on your computer from the below link and check.

I need you to be more clear with me. I entered my model number and it took me to a page with available software for my laptop. I do not know what «bios» means to update. Please be more detailed.
Also, an update. After following your instructions yesterday and removing that thing and refreshing to make it reappear my laptop has been acting way worse than before. It now will shut off immediately after I unplug it every single time and will not turn back on unless its plugged in. Before it would last for hours if I unplugged it and it would be able to turn on and last for hours when turning it on without being plugged in. I hope you can at least make it go back to how it was before because that was at least managable.
I did the HP Support Assistant battery check again this morning and this time it says: Charged 100%, Battery Unknown (93). It says a paragraph about it being unable to access the battery. It worked before I don’t understand what is going wrong after following your instructions! 😞
