Lab Services laptops and classroom computers have in the past used locks to thwart physical theft. A problem arises when security slots change or are removed by computer manufactures.

Lab Services laptops

Oct 2015

New Dell laptops, Latitude E5440 (bought 7/24/2014; deployed winter 2014/2015) have a security slot that differed from prior slots such that the old security clips (scissor-type) did not fit in as neatly. Status, as of Oct 2015:

Bob and Oliver confirmed that all three types of scissor clips currently work with the slot of these newest laptops, if the correct technique is used.
One report case in which one clip (of the "long" type) came out unexpectedly. But we could not reproduce the problem.

Decision:

Nothing to be done now since all seems to be working OK.
When buying new laptops for the program, test physical security on the new models before committing to full purchase

The specification the the nominal standard, as understood by Oliver:

Rather than use the current set of (cheap) scissor-type clips, we may need to consider more expensive and/ or less convenient options if this trend continues:

Replace one of the computer's screw (if available in an appropriate location!) with a security attachment:

Glue a security attachment to the computer.
- Either on the lid, bottom, or side. May affect stacking of the laptops, but not necessarily depending on options available. The right glue and its application is critical to its success.
Different mechanisms to use the ever-changing sizes of the security slot:

Classroom desktop computers

New Apple Mac mini's do not come with a security lock. (True as of 2011 Mac mini model?) Two options found:

Encase the computer. Examples:
Glue a security attachment to the computer.
