Note: TL;DR The original title of this post was Inspiron 15 7000 Gaming (7567) - dGPU apparently no longer detected. It was entitled as such because it was the last symptom noticed prior to discovering that the system cannot properly boot no more. Title now updated to reflect the current problem. On the next post, it will be seen that a stopcode (ACPI_BIOS_ERROR) is apparently what is happening.
I was originally satisfied with this laptop a person gifted to me, brand new, including receipt from retailer. It hit most, if not all of my desired things in a laptop. Sure, I had to update the BIOS a few times, experience a few random shutdowns (that eventually seemingly got fixed, yay), and undervolt a wee bit to give me better thermal breathing room, apart from putting it on top of a proper laptop stand for better cooling when doing some gaming.
I got this laptop last month (2018 02 09).
Yesterday, after a good round of Tekken 7 (with all settings on ultra, because I can), upon deciding to run another GPU-intensive app, the application tells me that I do not have a GTX 1050ti installed, even after running the said program with a right click (then selecting "Run with high performance NVIDIA processor"). I thought I needed a restart, maybe it's the only thing I needed.
Now I can't boot up the machine. Hangs after the swirly circle Windows 10 loading progress screen.
I have yet to do other troubleshooting steps other than...
Assuming that the power brick's LED would change color (from blue) if there was a power fault, there was none a change - it's still blue just like the day it was given to me.
As for how the undervolt was done, I have used Intel XTU and reduced voltage by 80mV. The GPU was underclocked through MSI Afterburner down to 1300MHz. To clarify things, there is no way to adjust voltages manually because it is disabled (as a safety feature), and it was good that there was such a thing. Yes, I am shortchanging myself a bit as far as performance goes, but the temperatures never exceeded 70degreesC thanks to this.
I have yet to try other things to see if it still works. See below for other things I might have already tried. It's rather sad that after just a month of steady use, gaming, internet browsing, movies, and some video transcoding, the laptop decides to fail. However, there might still be things I have not tried, or guidance I might very well need.
Is there anything else I can do?
System BIOS version 1.5.3
ePSA build 4304.14
Windows 10 Home FCU
Drivers updated as per auto-update mechanism.
I am contemplating on removing the SSD, slapping in a HDD, and try from there. And maybe a BIOS rollback. But then there might be guidance I might have missed or not know.
Thank you for any help given.
Did you make any recovery media for the system so you could work on it after signing in?
A missing display adapter may mean it has failed or is in the process of failing. On the system that happened to me, the boot was not effected. I do not know for sure if the device is included in the ePSA test but I would assume it was. Maybe I will run mine to see.
The 7567s have been having major problems with unwanted shutdowns which might be related to power issues. Possibly battery problems, so are you doing tests with and without external power connected?
Have you modified your system from factory configuration?
I assume you have reset you bios to defaults settings and if any changes were needed after that, you made those?
Thank you for the nice reminder, kind person *smile*
Yes, I forgot to try out the Dell Recovery Media I created first thing after acquiring the laptop. Also, I agree with your statement about disappearing hardware possibly meaning eventual hardware failure.
Please do try ePSA if and when you are not inconvenienced.
I was honestly surprised upon reading up on the boards and on other places about the seemingly-widespread "7567 issues" regarding power, unwanted shutdowns and things... I got the laptop while it was still in 1.00.05 (February 2018), encountered some shutdowns (which I simply dismissed as overheating at that time, since undervolting and raising the laptop 1" seemingly ended it), and went straight away to 1.5.3 when it came out. Yes, I have tried some of these tests with and without external power (unfortunately I forgot to note that in the previous posts), but thanks to your reminder, I retried most of them with and without external power just to see.
The results are apparently the same.
I have yet to modify the laptop from factory configuration. Also, you are correct in stating that I have reset the BIOS settings to defaults. I have to say that to the best of my weak knowledge, yes, the changes that were needed after that (to at least switch between Legacy boot and UEFI boot, and to dis/enable Secure Boot) were made by me, so far.
Continuing onward with results..
Sad. I guess I should at least check the warranty on this thing.
Thank you very much to all people. If there are things I have overlooked, please tell me. *bow*
I did not see a mention of the Nvidia GPU in the diagnostics.
I might suggest attaching an external monitor to see what happens. The Nvidia device seems to be involved in handling those types of monitors.
The fact you can't boot any USB media due to ACPI warnings would seem to indicate a service call may be necessary.
