Some Dell systems are not booting due to BIOS upgrades
Bleeping Computer reported that certain models of Dell PCs are affected by boot issues due to new BIOS updates. Users described their boot issues on the Dell community site and social media. These issues typically involve blue screens and shut downs, and while some devices will turn on, their displays will remain off. Other Dell owners have stated that their systems will turn off after a few seconds of being powered on. 'Time-of-day not set' errors are also appearing on some laptops.
Among the models experiencing problems are the Alienware Aurora R8 (BIOS version 1.0.18) and Dell Inspiron 5680 (BIOS version 2.8.0) desktops as well as the Dell Latitude 5320 and 5520 (BIOS version 1.14.3) laptops.
Some users have discovered a solution for laptops showing the ‘Time-of-day not set’ error by downgrading the BIOS. However, only devices that can boot have a chance to be fixed and the procedure is not simple, especially for common Dell owners. Furthermore, the boot issues may persist until the battery is removed and the fixes are not guaranteed to work. Thus, it is recommended that affected users contact Dell Support, utilize Dell’s official guides or wait for a working BIOS update.
