Windows 7 workstations keep locking after inactivity

I have two brand new windows 7 PCs being used for Point of Sale. They keep locking after short periods of inactivity. I have changed everything I know to change.

In the power options: The PCs are set to never go to sleep, the displays are set to never turn off, require a password on wakeup is set to Don't require a password, and hibernation is disabled.

The screensaver is set to None and the On resume, display logon screen is unchecked.

I'm stumped.

Your Point Of Sale software may initiate the lock for security reasons?  Check with the software vendor.

You may need to check the system BIOS as well. Some of the same settings for power savings are set there and can be independent of the operating system settings. Also check for updated drivers and windows updates, patches, etc. And if they are brand new, they are probably covered under warranty and support should be available.

Thanks for the replies:

They are fully updated, and there is really no Point of Sale software on the PCs, it resides on the Terminal Server. I don't believe this is a hardware issue, because it is Windows 7 that is locking. I don't believe Dell actually supports Windows 7 per se. I have deployed 10 of these in the last week: 8 for individual users and these two replaced the PCs at the Counter. These are the only two that I know of that are behaving this way.

Have you checked the System Bios settings?

What type of hardware is this?

BTW, the machine is not sleeping, but Windows 7 is locking.

You may have a power issue causing it as well. Make sure there is sufficient power / quality power at the wall or install a line-conditioning battery backup unit to test. Along those same lines, is there a lot of POS hardware plugged into the system? Perhaps they were spec'd with too small of a power supply unit to handle it? Something is different at this station and that is likely the cause of the problem. Installing a powered USB hub may help.
are they on a domain?  also check GPEDIT.msc and make sure local policy isn't causing lock issue.

I have not checked the BIOS settings as I am not on-site. These are Dell  OptiPlex 7010 Ultra small form factor. They are not sleeping, Windows 7 is just locking.

They are on a domain, and I will check the Group Policy settings now. It is my understanding that no policies have been set up yet, but I'd better look at that and check to see what container they are in with AD.

They are both plugged into a brand new APC Back-UPS.  

I think I've answered all the pending questions.

A/V protection? Have the users been browsing the web or opening emails? I had a client get hit with a zero-day infection last week that really rocked their systems. It didn't show up on any scans and nothing was there to stop it. Later on in the day the updates came out to detect it and we were able to solve the problem, but it was just too new at the time of infection to prevent. One of the symptoms was a lockup like you described.
Commented:
My apologies. I just discovered that there was a miscommunication between the end users and me -- it turned out to be the Terminal Server session that was locking that session, not the workstation, the screensaver was set on that profile. The setting has been changed and I am now waiting to hear if that fixed the issue.

If it does fix the issue, I'm not sure how to close this out?

That is your choice - points are free and unlimited, and much appreciated but you do not have to award any if you do not wish to. Or you can split them up between members that responded with answers that would have solved your problem if it had been what you thought. There are really no rules for such situations, but you can see how the system works below by clicking on the "point system" or "expert benefits" sections. Good luck!

Thanks to you all for being so prompt in trying to help me with my problem. The client supplies truck parts, and the employees are not very computer saavy, and are easily frustrated. I am glad this is resolved.
