Not sure if original issue is was resolved but I received the following email this morning. Hopefully it will help someone in the future.
Rockwell Software running slowly on DELL Computer
Problem
RSLogix or Studio 5000 is taking a long time to open. It is taking about 10 to 15 minutes, but when using my other computer it takes less than a minute; what is going on?
Environment
- RSLogix / Studio 5000
- FactoryTalk View SE or ME
- Other Rockwell software
- DELL Computer
Cause
Intel SpeedStep technology or
Enhanced Intel SpeedStep technology (EIST). EIST technology dynamically changes your CPU speed based on your computer's current circumstances.
For example, in one case the laptop was in a docking station and was not using the properly rated power supply, which caused the EIST to slow the CPU to the slowest possible setting. The performance hit was not immediately realized by the user until trying to open a VMware virtual machine to run RSLogix 5000 or other CPU intensive software. Re-running the "Windows experience index" revealed that there was something wrong with the graphics and CPU on the PC.
Solution
If using a Dell Precision M4800 (or any Dell Laptop), verify that you are using the correct power supply and that you have disabled EIST in BIOS. You can access your BIOS while the computer is booting, usually by pressing one of the Function keys (F2 for example). For more information on accessing the BIOS, refer to
