The single most effective fix for these aging issues is often overlooked:
The Basic Input/Output System (BIOS) is the silent sentinel of any computer. It is the firmware that awakens the hardware, initializes components, and bridges the gap between the operating system and the physical machine. For a complex, ultra-mobile device like the Dell XPS 13 9365 (the 2-in-1 model with a Kaby Lake processor), the BIOS is even more critical, managing everything from thermal throttling in tablet mode to the precise voltage required by its logic board. Performing a BIOS update on this device is not a routine software installation; it is a low-level firmware surgery that carries both significant benefits and non-trivial risks. For the owner of a 9365, understanding this duality is essential to maintaining the system’s security, stability, and hardware compatibility. Dell Xps 13 9365 Bios Update
This is the recommended method because Dell's software automatically downloads the right file. The single most effective fix for these aging
Make sure to reset your custom settings (e.g., Boot order, Virtualization for WSL). Performing a BIOS update on this device is
One of the biggest complaints for the 9365 is that the Thunderbolt 3 port stops recognizing docks, external SSDs, or displays. A BIOS update rewrites the controller firmware. If your Dell Dock (WD15 or TB16) disconnects randomly, a stale BIOS is likely the culprit.
