Hi, My XPS 8930 has been very fast booting from the time I bought it in late 2018. Booting got a lot slower after recent BIOS update -- surely to 1.1.18 but possibly starting with the earlier version. More details: 1. For many years and on several XPS desktops, I've had the Power Options > AC Recovery set to Power ON. Never had a problem. 1a. I recently doubled the RAM from 16GB to 32GB (Crucial Memory, of the same specs of the original 2 sticks). The memory was detected and there were no problems after the upgrade. All 4 sticks remain properly inserted. 2. After a recent day with extremely long boot (8:15 min), I changed the settings to Power OFF, and it booted in 1:43 min. I ran the full range of the Windows troubleshooting (several hours) and no problems were detected. 3. Following the great advice of [NAME] and [NAME]  here: [URL] and here: [URL] I cleared the CMOS and flashed the BIOS. I then re-set AC Recovery to Power ON, as I had it earlier on. The desktop now boots in about 1:50 min (from the start of the Dell logo screen to the Windows login page). However, in the Task Manager, under Startup, it says Last BIOS time 13 seconds (sometimes less). This is pretty absurd, after waiting for nearly 2 min for the PC to start. I know I can live with that... Still, it doesn't feel right. I have a new XPS 9510 laptop, same 32GB memory (but much faster processor, obviously) and it boots in no time. Would greatly appreciate your advice on how to get the desktop to boot faster. Thank you, JF
