When I first got my laptop in November, it would regularly come out of sleep mode by itself and give me a black screen with a blue text error box that said: Default Boot Device Missing or Boot Failed. Insert Recovery Media and Hit any Key Then select ‘Boot Manager’ to choose a new Boot Device or to Boot to Boot Recovery Media [OK]. Hitting OK came up with a screen that said there was no boot device. Powering off and on though - the system would reboot fine.
I now find that every few hours the system will give me a screen that says “Windows had a problem and needs to reboot” . That then leads to the same screen as I described above. Once again, I power off and on and everything is OK for another few hours.
I looked at the BIOS settings and they look fine. I opened the laptop and the drive and RAM all seem seated properly. Running Windows 10. Not sure what to try next.
What SSD are you using? Check for firmware updates. The WD drives in particular have had some issues that iirc were resolved by applying a firmware update to the drive.
Thanks for the suggestion. I have the WD Black SN850 2TB drive. Based on your suggestion I just now updated the SSD firmware. I did review the WD site and it appears the firmware update was mainly to fix some AMD related performance issues - so I’m not holding my breath that this will address my issue. But I will know shortly
