I have a clean version of windows 8.1 on my z710. The says that it does not support the ideapad line laptops. When will my device be supported? I don't want to download a version of the power management system that causes shutdown problems. Also will the work for my 8.1 system?
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 , the causes Acpi.sys to be loaded during system startup at the base of the . 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.
For each device described in the ACPI namespace hierarchy, the Windows ACPI driver, Acpi.sys, creates either a filter device object (filter DO) or a physical device object (PDO). If the device is integrated into the system board, Acpi.sys creates a filter device object, representing an ACPI bus filter, and attaches it to the device stack immediately above the bus driver (PDO). For other devices described in the ACPI namespace but not on the system board, Acpi.sys creates the PDO. Acpi.sys provides power management and PnP features to the device stack by means of these device objects. For more information, see .
A device for which Acpi.sys creates a device object is called an . The set of ACPI devices varies from one hardware platform to the next, and depends on the ACPI BIOS and the configuration of the motherboard. Note that Acpi.sys loads an ACPI bus filter only for a device that is described in the ACPI namespace and is permanently connected to the hardware platform (typically, this device is integrated into the core silicon or soldered to the system board). Not all motherboard devices have an ACPI bus filter.
Acpi.sys and the ACPI BIOS support the basic functions of an ACPI device. To enhance the functionality of an ACPI device, the device vendor can supply a WDM function driver. For more information, see .
An ACPI device is specified by a definition block in the in the ACPI BIOS. A device's definition block specifies, among other things, an operation region, which is a contiguous block of device memory that is used to access device data. Only Acpi.sys modifies the data in an operation region. The device's function driver can read the data in an operation region but must not modify the data. When called, an transfers bytes in the operation region to and from the data buffer in Acpi.sys. The combined operation of the function driver and Acpi.sys is device-specific and is defined in the ACPI BIOS by the hardware vendor. In general, the function driver and Acpi.sys access particular areas in an operation region to perform device-specific operations and retrieve information. For more information, see .
ACPI control methods are software objects that declare and define simple operations to query and configure ACPI devices. Control methods are stored in the ACPI BIOS and are encoded in a byte-code format called ACPI Machine Language (AML). The control methods for a device are loaded from the system firmware into the device's ACPI namespace in memory, and interpreted by the Windows ACPI driver, Acpi.sys.
To invoke a control method, the kernel-mode driver for an ACPI device initiates an request, which is handled by Acpi.sys. For drivers loaded on ACPI-enumerated devices, Acpi.sys always implements the physical device object (PDO) in the driver stack. For more information, see .
This option requires basic OS understanding.Select Your Operating System, download zipped files, and then proceed tomanually install them.Recommended if Acpi Vpc2004 0 is the only driver on your PC you wish to update.
The Microsoft ACPI Driver service is a kernel mode driver. If Microsoft ACPI Driver fails to load or initialize, the error is logged and the computer attempts to restart, using the Last Known Good configuration. If the Last Known Good configuration fails, Windows 8 startup also fails, and the boot process halts with a Stop error. If you disable this service, Windows 8 will fail to start. Do NOT change this service startup configuration if your computer is working.
Don't let them convince to purchase a new system. With a SSD these "old" netbook become useful devices that last up to 9 hours on a battery charge. With a registry tweak you can even run at a resolution of 1152 x 864 if the screen lets you.
run regedit and search (F3) for Display1_DownScalingSupported. Change the value in HEX(1) Windows 8 and above will automatically change all values. Windows 7 has about 2 values that need to be changed manually.
The driver you installed only takes up memory. If you want you could go further and check if it's only the registry key that is needed, but since it's not even my system and cleanup programs could delete it I'm ok with this sollution.
If you don't have the right hardware for the mousepad as in my case it will just show ON even if you press the hotkey. After a Windows 10 upgrade you will again have to edit the registry as I showed to increase the resolutions possible.
hi, That seems to be the Lenovo Paper Display Driver as discussed in this thread. I don't see a Windows 10 version of this driver yet but can you consider reinstalling the Windows 8.1 version below and observe (run it in Win8 compatibility mode if necessary).. Lenovo Paper Display for Windows 8.1 (64-bit)ver.1.0.0.022 Let me know how it goes. Regards
Both drivers now were visible in the device manager.- it is now possible to approach described above. Good luck to all to get this working. HanspeterK Solved! Hi there are many out there who seem to have the same problem after the Windows 10 upgrade to your Acer: the touchpad did not work any more.Connecting an external USB mouse works perfect. Here is what I did to get it running again:- I checked in the Device Manager all drivers and noted that the Intel Serial IO Driver had a yellow exclamation mark- for security reasons I made first a new restore point- then I uninstalled the IO driver and downloaded the latest version from the Acer Support pages:IO DriversIntelSerial IO driver now visible in the device manager. Go try to install and uninstall the Synaptics touch pad driver, and here I am not sure if that had an impact to get it working. At least there is no Synaptics to Solution. So this is the only "insecure" component on the Driver604.10135.1001.530013.4 MB20150811You need of course to check the right version for your own model, the above is for the Acer Aspire V3-112P- I installed the driver in normal mode (no compatibility mode) and restarted the computer AND I removed my USB mouse during the restart- now the touchpad was immedidately recognized and it started to work and it also showed up as a HIDPS2 mo...
This will install the chipset INF files so that of the drivers on that page (other than the intel wireless LAN and bluetooth as the yoga has Broadcomm). Any thoughts or direction would be massively appreciated! Thanks!

Go to Solution. Windows properly recognizes the virtual power controller ACPIVPC2004.' All apparently clear. Hi all, first post here... I am re-installing Windows 8.1 and the required drivers for my Yoga 3 Pro (to get rid of Superfish, started the task before the Lenovo tool came out...) I am almost there, except for one unknown device in the Device Manager, which has a code in its detail of ACPIVPC2004. A quick google gives me a link to - Lenovo http:support.Lenovo.Comusendocumentsht071645 - and a page which says 'Download and run the Energy Management from Lenovo support website with the proper Operating System version.
It looks like the power extract it from my install. Can you install it and let me know if the driver installs as well? If not, I can management comes from One Key Optimizer.
Go the driver on my Y430 any help will be appreciated? Solved! I have this unknown device that need to install to Solution.
black screen as soon as i unplug the windows screen comes back. Not sure if these Solution. When I plug in my power cord to charge i get a device in device manager. I have a unknown Solved! View are related or not.
Hi: I am pretty sure you need this driver. The latest is sp65474.Exe I don't know if not having that driver installed is related to the black screen issue. Intel Sideband Fabric Device Driver is a bridge tothe Intel Dynamic Platform and Thermal Framework. This package isprovided for supported notebook models that are running a supported operating system. File name: for W8.1. This package provides the driver that enables the Intel SidebandFabric device.
I purchased Windows 7 Home Premium 64bit from Lenovo and did a fresh install on my Y530. After adding every possible Windows 7 driver from http:consumersupport.Lenovo.ComusenDriversDownloadsdrivers_list.Aspx?CategoryID=13 I still see one Unknown Device in the Device Manager. The device is identified as ACPIVPC2004. I guess that's a power management device, and the driver's name is "ATK ACPI driver". I downloaded it from http:consumersupport.Lenovo.ComusenDriversDownloadsdrivers_show_2864.Html . After installing the "ATK ACPI driver" I reboot and still see the unknown device, ACPIVPC2004. Is there a driver that works for the ACPIVPC2004 device? To Solution. Go Solved!
Hello, I have a lenovo b470, in my computer management, i can see that i have an unknown device with the value of ACPIVPC2004. And it as been so for a while now.
