Your experience is quite similar to mine. Except my Inspiron would sometimes take up to 15 minutes to startup while thrashing the HDD. Startup / shutdown now take less than 30 seconds with an SSD.
Hi ... I have an Inspiron 3593 with Windows 10 recently updated to ver 21H1 May 2021 update. Recently it started taking on average 5 minutes to shut down and 4 minutes to boot up. I searched the web and tried everythibng I could find to resolve the problem. Nothing made a difference. Two weeks ago I did a full reinstall of Windows 10, completed all updates and ran all options in Dell SupportAssist. It still takes 5 minutes to shut down and reboot.I then started with F12 to run at diagnostics. Looking through the BIOS and config options I noticed under Configuration 'M.2PCle SSD-0/SATA-2' I have never installed an SSD and the original HDD is still listed under boot options.What exactly is this and where does it come from? Do I need it and if not how do I remove it?
