I have a laptop (Compaq) with an AMD chip in it. Not sure exact model right now, but this laptop is about a year old and running XP home. Here is the problem and what I've done to diagnose the issue.
1. After Logging in, I noticed that the CPU is at 100% (via task manager) and that doesn't go away. The System process is constantly running close to or at 100%.
2. When I try to shut down, it goes from "Logging of user". to "Sutting down" and stays there. I have to hold down the poser button to turn off the laptop.
3. I ran the performance monitor and noticed that System thread 21 was way higher than the other threads. Looks like ACPI.sys is on that thread.
4. I notice, that the fan spins lightly when the login screen appears, then at high speed soon after logging in, and it doesn't stop. I tried to look for ACPI swith in the BIOS, but couldn't find any. Or any reference to ACPI in the configuration files through MSCONFIG.
5. I read somewhere (not here) that a registry setting has to be made. I made the change, but the issue doesn't go away.
If anybody has any thought or ideas what I should try, please let me know. Thanks.
