Dell XPS 15 9550 - SYSTEM BIOS 1.9.0 Issues

What BIOS version were you on before 1.9.0?  Any issues with it?

Was any other driver updated around the same time as the BIOS was updated?

Thank you for your message. Since the devices are working fine when not in the diagnostic screen it confirms that the hardware is fine.

Please try running a diagnostic using the Dell Support Assist application & check if there is any error reported in any of these devices.

What is the status of the power button light when the screen is stuck on the blank screen, does the power button light blink or stays steady?

For my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (Dell-Sreejith R) & send a private message with the service tag, registered name & email address.

How to find service tag.

Hi Bluekiller007,

"Also I've had some incidents, few of them, where the system would be stuck on a blank (black) screen and had to be hard-shut-down from the power button as there was no way to revive the screen and access the system. This would happen after the laptop would be left untouched for a long while and normally should have gone to sleep or hibernation." 

I have the same problem then you. Did you find some solution for that?

I have the same problem with V1.9.1 - constantly freezing after sleep.  I have Samsung nvme M951 .  I tried many different drivers including the last one - the same.  It appears that the hard drive stop responding ,  screen mouse is moving but the system is blocked.  Any suggestions?

Thank you for your message. Have you observed this issue with the original hard drive that was shipped with the computer?

Does this happen only when you wake the system from a sleep mode or does it happen when booting from a complete shutdown or restart?

Did this happen before the BIOS upgrade?

Service tag : 

This is the original HDD with the system : W53CK

HDD FW: BXV76D0Q   - whre  to find nvme FW update? 

Samsung NVMe driver 3.0.0.1802

It happens with all different bios -V1.4  /  V1.6.1 / V1.9.1 

It happens only after sleep  - every 20-30 sleep cycles.

When RAID is enable in bios it happens every 3-5 sleep cycles

How can I troubleshoot?  Any other info needed?

Thanks in advance

I think the xps was stuck while trying to sleep, because power button was lit, but hitting keyboard or touchpad would not wake the screen. Pretty sure it’s a bittorrent bug (see my replies above).

In my case I suspect using bittorent and a particular option in it, to quit bittorrent when all downloads complete, I think that interfered with windows sleep or hibernation (both of which I have enabled). I did not use that option again in bittorrent and the problem has not reoccured.

System is still with original SSD SK Hynix 256GB

The support assist diagnostics did not show any problems.

The power button was lit and steady while the unresponsiveness problem happened. But as I mentioned above this could have been caused by me using bittorrent and choosing the “quit bittorrent when all downloads complete” option. It also has options such as “shutdown when all downloads complete” so I think that somehiw bittorrent getting permission to either quit itself or shut the computer down interferes with windows somehow...
