Welcome to the Dell Community [NAME]  Have you tried replacing your CMOS/BIOS battery??? Best regards, U2
Hi all,I use a laptop latitude 5510 with an i7-10810U, and he switches randomly bios parameters from AHCI to RAID ON. I would like to know if someone knows a sustainable solution to fix it. The first time it happens, I was under Ubuntu 20.04, and I lost all the data on my NVMe SSD. It happens when I connect a screen to my dell docking station wd19 using the display port. Once I plugged the screen, the computer started to reboot 3 to 4 times before a black screen occurs, saying "SGX disabled by BIOS". Once it was done, my SSD was automatically reformatted.To solve it, I have just switched SGX to OFF and RAID ON to AHCI and reinstalled a new Linux on it.The second time I was under Fedora 36 and, this time, my NVMe didn't reformat. It happened randomly while I was working on it. I was using a WD19 docking station with 1 screen plug on it. Once again, the computer started to reboot to conclude on a blue screen, and the BIOS AHCI parameter switched to RAID ON. Furthermore, BIOS' date time changes to 03/30/22 instead of 07/08/22 (before reboot it was at the correct date).To fix it, I've just switched back the parameter, and the computer reboots correctly.It also happens to my colleague (under Windows 10) once he connects throw an HDMI port to a projector. I don't have much information on it, but BIOS parameters have switched too. I paid attention to updating all as soon as possible (drivers and BIOS). Have ever heard of similar problems and have you a sustainable solution to fix them?Otherwise, have you any idea of the source of the issue? Thanks in advance.
