Quanta TWS schematic at revision 1A, a 1.63 MB PDF that appears to be a duplicate copy. The name lists only the project code and revision, so the platform, chipset and graphics configuration must be read from the document itself. Quanta prints such codes on its boards, which is the best way to confirm a match since the retail model name differs. Open it in a PDF viewer to trace supply rails, check the power-on sequence and find component values around a faulty area. Verify the revision first.
