To be eligible for support from LSCR under our annual desktop support program, computer hardware must meet certain minimum specifications, which are detailed below. In general, we recommend that computers be replaced every three years, and computers older than four years may not be supported.
Also detailed below are our recommendations for new purchases. Note that computer models and configurations available from different manufacturers change often. The recommendations below are current as of the date this page was last updated. In addition, LSCR recommends that all computers be purchased with a three-year extended warranty (next business day service, if available).
Please check with your LSCR consultant for a detailed computer recommendation before purchasing your computer. LSCR reserves the right to refuse support for any machine below our suggested levels. Please see Definitions of support level terms for details about the terminology used in the tables below.
