When BTX died around 2009, Dell was left with proprietary designs:

Using a low-resolution or generic screenshot can ruin a delicate board repair. A high-quality, professional-grade vector schematic offers several distinct advantages:

Finding a "high quality" schematic for these proprietary boards is challenging because Dell does not publicly release them. However, specific versions are available through technician-focused archives and repair communities. 🔍 Identifying Your Board
