How to Update ACPI

Update your ACPI software drivers with the Windows Update utility.

The ACPI (Advanced Configuration and Power Interface) on your Windows-based computer is used for power management of batteries and power cables connected to the computer. Because of the importance of this software, you need to keep the drivers up to date. The Windows Update utility on your computer will retrieve and install all of the current drivers for your ACPI. This software comes with all Windows computers so you do not have to download it.

Instructions

1. Open the Windows "Start" menu and select "All Programs" from the menu.

2. Click on the "Windows Update" icon in the menu.

3. Click the "Check for updates" button.

4. Click on "ACPI Update" in the menu. If you don't see an available update for ACPI, then your software is up-to-date and no further action is required.

5. Click the "Install updates" button at the bottom of the screen and wait for the APCI update to finish installing on your computer.

6. Reboot your computer for the drivers to take effect.
