How do I enable ACPI on my machine/change the HAL?
March 26, 2000
A. If during Installation you disabled ACPI to solve a problem (asseen in Q. How can I specify an alternate HAL during Windows2000 installation?) you may want to enable again at a later time andthis can be done as follows:
Right click on 'My Computer' and select Properties from the context menu
Select the Hardware tab
Click the 'Device Manager' button
Expand the Computer object
Its type will be shown, probably 'Standard PC' (if it says (Advanced Configuration and Power Interface (ACPI) PC then ACPI is enabled already)
Click here to view imageRight click on the Computer type and select Properties
Select the 'Driver' tab
Click 'Update Driver'
The Upgrade Device Driver Wizard will start. Click Next
You can now either ask it to find a driver or manually select
If you select Manual select the 'Show all hardware of this device class' and select the ACPI driver. Click Next
Click Next to install the driver
Click Finish to the wizard and click Close the computer property driver dialog
Click Yes to restart your computer
Be careful with this though, if you select a HAL which your computer is not compatiblewith you may experience problems.
