Archive of high-resolution board photos for a Huawei laptop board DAH97AMBAD0 revision D, 19.3 MB RAR. The DA prefix is Quanta's numbering pattern, so Quanta is the ODM behind this Huawei board. Photos help a repair technician compare component placement, identify markings on small parts and check for missing, burnt or misaligned components, especially when no boardview is available. Make sure the board number and Rev D printed on the PCB match before using them as a guide.
