Hey fellow, I’ve had a similar experience with my Latitude (older model), and I feel your frustration—it sounds like a mix of power delivery, BIOS instability, and possibly failing hardware. In my case, a static power drain (holding the power button for 30+ seconds), a full CMOS reset, and reinstalling audio drivers after a BIOS update helped temporarily. The random shutdowns and BIOS lockups turned out to be tied to a failing battery and internal power board, even though diagnostics initially showed no issues. If you haven’t already, I’d definitely check for any signs of battery swelling and try running SupportAssist logs when you can keep it powered on. Given the stack of issues, I’d strongly lean toward a deeper hardware fault—if you're out of warranty, it might be worth getting it looked at by a tech
