HP Probook mt41 640 650 Speaker Module 738404-001 Renewed

The HP Probook mt41 640 650 Speaker Module (part number 738404-001) is a renewed left-and-right speaker assembly designed as a direct drop-in replacement for supported HP Probook laptops. When the built-in speakers in your Probook mt41, 640, or 650 start producing distorted, tinny, or no audio at all, this module restores the original sound output without requiring a trip to a service center. The dual-speaker design comes as a single unit, which simplifies installation — you replace the entire assembly rather than dealing with individual speaker components.

Because this is a renewed part, it has been tested for proper function and electrical continuity, making it a practical alternative to new OEM stock that may be difficult to find for these older Probook models. Installation does require removing the bottom panel and potentially the keyboard bezel depending on your specific model revision, so a basic toolkit and familiarity with laptop internals is recommended. Cross-referencing the part numbers 738404-001, CY302, or CY351 against your existing module before ordering will confirm compatibility and help ensure a smooth swap.
