Dec 22, 2016 I have a Dell Inspiron 7537 laptop. Had Win 8.1, and has been upgraded to Win 10. The hard drive went bad, so replaced it and installed Win 10. My issue is, and I have found others here having the same issue, is finding the correct driver for what I have read is the Hard drive motion sensor.

Many people spend money unnecessarily replacing laptop batteries when they may have fixed the issue with a simple battery reset or a Drivers update. If you are having problems charging your laptop battery, then reading this post may save you a lot of time, money and frustration!
Battery not charging – “0% available (Plugged In, Not Charging)”
With this error you may or may not see the charging light on your laptop, either way your laptop is having problems charging.
Batteries do have a finite lifespan (600-1000 charges/ discharges or about 2 years depending on intensity of use) and they can be very expensive to replace, so before throwing out that battery (in an environmentally-appropriate manner of course!), ensure that it has actually reached the end of its life and there isn’t some other problem preventing it from charging.
Windows 10 laptop battery charging issue
Some updates in Windows 10 have been know to cause the laptop battery to stop charging. There is a simple solution to this:
- go to Start > Device Manager
- select Batteries > you will see
Microsoft AC Adapter and
Microsoft ACPI-Compliant Control Method Battery - Right-click on each individually > choose Uninstall device (they will reinstall when you restart your laptop but always run a backup first just in case!)
- Turn laptop off and unplug the power cable
- If your model has a removable battery, then remove it and then replace
- plug laptop back in and power up
- check to see if the battery is charging
Fix 1: Battery Reset
To reset your laptop battery you will need to run the battery down completely. Make sure all work is saved as you will run the battery down until the system shuts off. When this happens you should plug in the power cable but DO NOT turn back on the laptop. Wait until you are confident the battery is back to a full charge again and then turn on your laptop.
If this method does not fix your recharging issue then you can try to fix or update your laptop battery drivers by uninstalling and reinstalling them (make sure to create a ‘restore point’ in System Restore before manually updating Drivers files). You can use a Driver Update Tool to keep all your Drivers up-to-date if you prefer not to attempt this manually.
Fix 2: Update Drivers
You will need to uninstall and reinstall the relevant device drivers via the Device Manager.

– Select Start > (right-click) My Computer > Properties
– Select the Hardware tab
– Select the Device Manager Button
– Under Batteries right-click “Microsoft ACPI-Compliant Control Method Battery” and click Uninstall
Your battery should no longer be visible in the Batteries list. To reinstall it you will need to:
– Select Action menu
– Select Scan for hardware changes

– Your driver should be listed again
You can use a driver update tool to automatically update your Drivers if you are unsure of which ones you require. Driver errors can also occur when the Driver is outdated. For this reason it is necessary to regularly update your Drivers. The easiest way to do this is by using a Driver update tool but you could also search for and download the drivers yourself.
Test your battery now and if there is still a problem charging, then it may have just reached the end of its’ days and it is time to part company!

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.

ACPI devices
The hardware platform vendor specifies a hierarchy of ACPI namespaces in the ACPI BIOS to describe the hardware topology of the platform. For more information, see ACPI Namespace Hierarchy.
Microsoft Acpi Driver Windows 10
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 Device Stacks for an ACPI Device.

A device for which Acpi.sys creates a device object is called an ACPI device. 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.
All ACPI functionality is transparent to higher-level drivers. These drivers must make no assumptions about the presence or absence of an ACPI filter in any given device stack.
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 Operation of an ACPI Device Function Driver.
An ACPI device is specified by a definition block in the system description tables 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 operation region handler 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 Supporting an Operation Region.
ACPI control methods
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 IRP_MJ_DEVICE_CONTROLFree ecodial software download. 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 Evaluating ACPI Control Methods.
ACPI specification
For the latest Advanced Configuration and Power Interface Specification, see the ACPI 5.0 specification available from the Unified Extensible Firmware Interface Forum website.Revision 5.0 of the ACPI specification introduces a set of features to support low-power, mobile PCs that are based on System on a Chip (SoC) integrated circuits and that implement the connected standby power model. Starting with Windows 8 and Windows 8.1, the Windows ACPI driver, Acpi.sys, supports the new features in the ACPI 5.0 specification. For more information, see Windows ACPI design guide for SoC platforms.

ACPI debugging
Acpi Driver Dell Computer
System integrators and ACPI device driver developers can use the Microsoft AMLI debugger to debug AML code. Because AML is an interpreted language, AML debugging requires special software tools. Checked versions of the Windows ACPI driver, Acpi.sys, contain a debugger component to support AML debugging. For more information about the AMLI debugger, see ACPI Debugging. For information about how to download a checked build of Windows, see Downloading a Checked Build of Windows. For information about compiling ACPI Source Language (ASL) into AML, see Microsoft ASL Compiler.
