We are seeing odd behavior using certain HP Compaq minitower PC's.
We have two types of machines.
In the Control Panel System Properties, both machines state the following:
Microsoft Windows XP Professional
Version 2002
Service Pack 3
Intel(R) Core(TM)2 Duo CPU
E8400 @ 3.00GHz
2.99 GHz, 1.93 GB of RAM
However, if you press F10 to get into the BIOS settings, the problematic
PC states HP Compaq 8000 Elite CMT PC and the good PC states HP Compaq
dc 7900 Convertible Minitower. There are also other subtle differences
in some other BIOS settings but the one particular setting that is causing
us problems with the 8000 Elite is in the Power OS Power Management settings.
On the 8000 Elite, there is a setting called Idle Power Settings which was set to
Extended. This setting does not exist on the 7900. On the 8000 Elite, with the
setting set to Extended, a simple delay steps take a long time to execute.
For example, a 60 second delay will take up to 10 minutes to run. Delay's
added to popup's have the same behavior. What we also noticed is that the
total Execution time in the report is way off. A test that takes took 16hrs will
only report around 87 minutes in the test report. If we change the setting from
Extended to Normal on the 8000 Elite, things behave normally.
Has anyone else witnessed such behavior?

There is a known issue with some hardware not properly specifying the right timer to the OS and/or not implementing the timer properly. See the following thread:

There is a workaround in that thread. Also installing a newer version of the BIOS from the OEM might also work.
See the thread for more details and let us know if you have any questions.
