HP L22319-001 is a 1.0 m power cord for connecting a wall outlet to a compatible power module. It uses a C5 connector at the module end, making it a cord component rather than an AC adapter.
The cord has a straight form and is listed by HP as a premium North American part. Its length supports placement of the power module within reach of the outlet. HP notes that power cords and power modules are usually separate parts, so this item is the cord itself.
