Control rechargeable batteries
(ACPIin laptops).
ACPI provides a general event handling mechanism that can be used to handle system events such as temperature changes, power management, plugging in, adding and removing devices, etc. This event handling mechanism provided by ACPI is very flexible because it is very flexible. does not give an exact description of how this event is routed to the chipset logic for processing, i.e. it can be implemented different ways, depending on the features of the hardware and operating system. When operating system is in an inactive state, but not in Sleep mode, it can use ACPI commands to put the processor in low power mode. ACPI describes the mechanisms for switching a computer to / from Sleep mode, and also describes general principles how different devices can wake up the computer. This allows the operating system to transfer computer devices to low power consumption modes, using the capabilities and features of software applications. ACPI tables describe the various devices on the motherboard, their energy states, the energy-saving modes of peripheral devices connected to the motherboard, and methods for putting devices into various energy-saving modes. When the operating system is in an idle state, but not in Sleep mode, it can use ACPI commands to put the processor into low power mode.
Battery Management Policy now moved from ARM BIOS to ACPI OS (operating system with ACPI support). The ACPI Compliant Battery Management Module requires one of two interfaces to function:
Smart Battery Interface, which is controlled by the operating system directly through the interface
built-in controller;
Control Method Battery Interface, which is fully described by AML control methods (micro-programs) and allows equipment manufacturers to select any type of battery and any type of interface supported by ACPI.
Batteries must be manufactured in accordance with the requirements of these interfaces, although other standards are allowed. The operating system has the ability to change the characteristics and behavior of the batteries, for example, it can change the points at which the messages "Low Battery" and "Battery Warning" are generated. If several different batteries are installed in the laptop, then the battery management subsystem must synthesize the so-called "composite battery", carried out on the basis of data transmitted from individual batteries. Now, when using ACPI, the operating system can carry out this work on the synthesis of the "composite battery", and the presence of a battery management subsystem is not required.
Author Dmitry Stepanov asked a question in the section Software
QUESTION. Battery with Microsoft ACPI Compliant Control. and got the best answer
Answer from Andrey Blagov [expert]
it is not necessary to disconnect, in principle it is not necessary to put firewood, but you need to look.
best of all, in the device manager, look at the properties of the device and on the information tab, copy the device code and enter it in the search engine on the devid.info website and there you will find a driver for it
Answer from Evgeny Zarudny[newbie]
Microsoft ACPI Compliant Battery
This driver is responsible for operating the laptop on battery power. If the battery controller tells this driver that the battery is running out, the system will warn you about this and offer to connect Charger... If you do not have time to use the charger, the computer will go into hibernation mode, that is, the next time you turn on the computer, continue to work from the same place as before entering hibernation mode.
Well, if this driver is disabled, then the battery will not be managed.
In my case, the battery controller glitched and my laptop started working on battery for 10-15 minutes, I disabled the "Microsoft ACPI Compliant Battery" driver in the device manager, now the computer runs for about 2 hours. The only drawback is if the battery runs out, then the computer is cut down and all the data with which I worked is lost.

Checking the battery capacity of your laptop will help determine if the battery is working normally or if it needs to be replaced. The battery capacity can be checked both within and outside the operating system.
Notes.
- Battery capacity (or battery life) is the amount of time the computer can operate on a fully charged battery. It is natural for all types of batteries to have a slight decrease in battery life over time. Each time the battery is charged or discharged, it loses very little of its capacity. This is considered a normal characteristic of a rechargeable battery and not a malfunction covered by the warranty.
- For getting additional information go to Dell Knowledge Base article. See What are the best practices for handling worn, swollen batteries and replacing the battery on a Dell laptop?
If the battery capacity is normal, go to next step.
BIOS is firmware that is embedded on the system board of a computer. BIOS update to latest version can help the PC to recognize the power adapter. To update the BIOS to the latest version, the laptop must be running on AC adapter and battery power.
A warning. Before updating BIOS on a Dell laptop, you need to install the battery and connect the laptop to the network alternating current... On some Dell laptops, the BIOS update can only be performed when the battery has at least 10% charge.
If the type of power adapter is not recognized by the computer, refer to Dell Knowledge Base article. Before forced update Please see the BIOS disclaimer below.
Attention! If the battery has less than 10% charge, you might need to force a BIOS update from DOS environments... Failure during this procedure can render the system unusable. Users perform this procedure at their own risk.
