These are almost exclusively proprietary designs. You cannot swap a HannStar board from a Dell laptop into an HP chassis, even if both boards have the "K MV-4 94v-0" stamp. Common Issues and Troubleshooting
While the "MV-4" marking doesn't tell us the CPU socket or RAM type, boards bearing this mark generally share high-quality construction standards common in the mid-2010s. If you are attempting a repair on a board with these markings, keep the following in mind:

Understanding what these labels mean—and how to find the actual part number—is the key to sourcing the correct replacement components. What Does HannStar K MV-4 94v-0 Actually Mean?
