How to Download ACPI Drivers
Download Drivers Using Hardware ID
Usually, we can download drivers from manufacturer’s website by using the device name and the system version. But for ACPI, it is impossible to get the exact device name. This makes it harder to download drivers in this way. In this case, you can use its hardware id to search and download drivers.
If you are not sure how to get the hardware id, follow these steps.
1. Go to Device Manager.
2. Right-click on the Unknown device and click Properties.
3. Click Details tab and click the drop down menu of Property.
Select Hardware Ids from the drop down menu and the value field will populate with a list of values.
Right-click on the top-most value and choose Copy from the menu.
Copy and paste the Hardware ID value into the search engine you like. You can also use your OS version and the key word “driver” to search the driver.
Download and Update Drivers Using Driver Update Tool
An easier way to download and update the ACPI drivers is using a driver update tool, which you can search online easily. It is recommended that you use Driver Easy if you have no idea what driver update tool you can use.
You can use Driver Easy to fast scan your computer to detect all problem drivers including the problem ACPI drivers. Then Driver Easy will find new drivers for you.
Driver Easy has Free version and Paid version. Both versions can be used to download drivers freely. But with Free version, the download speed is limited due to a large volume of users connected to the same server, and drivers are required to install manually. To get higher download speed and save more time, you can consider using the Paid version. With Paid version, all drivers can be updated automatically with just one click. You will have 30-day money back guarantee. You can ask for a full refund if you want.
