  1. What is ACPI driver?


    I found a program on SourceForge that supposed to find drivers that are not installed on the computer. I have a device that is labelled as unknown so I used this free software to figure it out. Apparently it requires an ACPI driver? What is it and what does it do?

    :)

    Drivers: What is the difference between ACPI for Windows 10 and Intel Chipset?

    Someone suggested uninstalling ACPI and then reinstalling might fix a bug that is preventing my battery from charging in Windows 10. Another post seems to indicate that ACPI and Chipset Driver are the same thing, but it is not listed under Battery with ACPI
    but under IDE ATA/ATAP controllers (whatever that is).

    I have two versions of Chipset for Windows 10, one from Intel's site via Microsoft and one from Lenovo, my computer, and they are not the same size. I think the Intel is the one I installed. Should I try the Lenovo version and see if that solves my problem,
    even though it doesn't seem to be directly related to energy management? I am so confused!

    Hi,

    Thank you for posting on Microsoft Communities.

    I would like to inform you that you can run Windows update to install the latest drivers for your hardware devices. You may also go to the manufacturer website(Lenovo) and download the drivers.

    Advanced Configuration and Power Interface (ACPI) is a power management specification developed by Intel, Microsoft, and Toshiba. ACPI, which will be part of the next version of Windows, enables the operating system to control the amount of power given to
    each device attached to the computer. With ACPI, the operating system can turn off peripheral devices, such as a CD-ROM players, when they're not in use.

    As you have mentioned that you are facing issues with battery, I suggest you to either visit your manufacturer website and install the latest version of drivers or run Windows update.

    Hope it helps.

    What is the make and model# of your computer?
    If your computer uses a UEFI Bios, then you may need the ACPI Driver ACPI - Advanced Configuration and Power Interface
    Go to the computer/motherboard manufacturers support/download drivers site, type in your model# and choose your version of Windows 10 (ie) 32bit or 64bit and download the ACPI driver for your model.

    Getting drivers for your system from sources other than MS, the device hardware manufacturer, or your OEM is risky. Please post what this program is and update your system specs so we have an idea what you have. At the bottom of any of your posts, you will see this:

    Click on it, you will see this:

    Click on it, follow the instructions, and fill in as much as possible. Make and model (complete) of your system is most important.


    Thanks, TC

    The Windows ACPI driver, Acpi.sys, is an inbox component of the Windows operating system. The responsibilities of Acpi.sys include support for power management and Plug and Play (PnP) device enumeration. On hardware platforms that have an ACPI BIOS, the HAL causes Acpi.sys to be loaded during system startup at the base of the device tree. Acpi.sys acts as the interface between the operating system and the ACPI BIOS. Acpi.sys is transparent to the other drivers in the device tree. Other tasks performed by Acpi.sys on a particular hardware platform might include reprogramming the resources for a COM port or enabling the USB controller for system wake-up.

    I used to get that unknown device on my older ASUS desktop PC's. I hunted around the ASUS site and found the needed driver. Then did an update driver from device manager and pointed to the downloaded driver. Now its installed during setup, or shortly after via Windows update. I haven't had to install it manually for a while now. Not since I upgraded to Windows 10 "I think"? Memories not what it should be some times. Right click the unknown device in device manger, select update driver, and then let it look online. It will seem like its taking forever but just let it do its thing and see if you get lucky. If that doesn't work then go hunting for it. Looking at my saved drivers for that PC, ATK is what I think had the ACPI driver in it.

  9. ACPI is required to properly shutdown, sleep, wakeup a computer, also to manage power profiles and etc.
