My Computer Won't Shut Down Itself After Installing XP
There are a number of users who are noticing that their PC will no longer automatically power down/shut off without pressing the power off button on the computers unlike in Windows Me/95/2000. There could be a number of reasons for this - but the main one seems to be that ACPI is not enabled on the computer or in Windows XP. Here is how to try that out:
1.
Click - Start - Control Panel - Performance and Maintenance - Power Options Tab
2.
Then click APM - Enable Advanced Power Management Support
