In general, white box is a term used to describe custom-built computer systems. These systems are usually built by a local computer store or by small computer manufacturers. In most cases there isn’t a way to lookup PC warranty information for white boxes via the internet.
For white boxes and other small computer manufacturers, WIR will calculate the most likely hardware warranty start date for a computer by using a variety of methods.
Based on this data, WIR will then set a 1-year hardware warranty end date. Additionally, WIR will set the Data Source Check to 21 in order to signify that this is a calculated value.
Knowing the hardware warranty start date is useful for identifying the age of your computers when WIR is unable to obtain the warranty information directly from the hardware manufacturer.
