The following laptops have an audible coil whine noise that is heard whenever the laptop is under a graphical load. This problem is seen with the AC adapter connected and using programs such as SolidWorks. The abnormal noise can be heard when rotating or rendering a drawing in SolidWorks. Affected Platforms: Dell Pro Max 16 Plus MB16250 Dell Pro Max 18 Plus MB18250 Affected Operating System: Windows 11
The laptop uses a 48 V three level buck power structure. (A step-down Direct Current (DC) to DC switching converter with two extra switches and a flying capacitor.) The increased voltage under graphical loading causes the expansion and contraction of components when Alternating Current (AC) voltage pass through them. This leads to Multilayer Ceramic Capacitor (MLCC) and Choke vibration which creates an audible whining or buzzing noise.
