I recently did a BIOS update on my system (1.12), which caused over-heating, and on Dell's advice, I rolled the BIOS back to 1.11, which was the last stable one.
Last night I got the notification from Windows Updater, however, that there's a Dell, Inc - Firmware update (0.1.12.0), and I just wanted to double check that this doesn't include a BIOS update as well, as I really don't want to risk my laptop at this point. Any help would be appreciated.
Windows 10 pushed an update to me today and at first the update came back failed.
I just now finished it and it said successful. I suspect the fail caused my D drive to disappear.
Not really sure what the deal is there. But I did the update before seeing this post.
So hopefully the over heat is not an issue and it stops dropping my D drive.
It did have a firmware payload.
I am on a G7
I've just installed BIOS 1.12.0 and now I can't undervolt my CPU anymore. Before the BIOS update I was able to underclock the CPU to -0.150 mV (Core/Cache Voltage Offset via Intel XTU), which is the only way I found to keep the CPU from thermal throttling. Now, the Intel XTU core voltage offset slider is disabled, furthermore I'm not able to rollback to a previous BIOS version (1.11.1 or 1.9.1). I got this error message while running the BIOS update: "ME Firmware EndUpdate Failed Error: 0x000001F3".
Windows device manager shows no errors on the Intel Management Engine Interface.
ThrottleStop also has no effect anymore.
Now, my CPU is thermal throttling like crazy! This is unacceptable, please help.
I've gattered more information that may help us. The 0.1.12.0 BIOS is correcting many (well known) security issues which are related to Intel CPUs. Maybe that's why it's not possible to roll the BIOS back to a previous version...
Just a heads up, do not bother taking this problem to Dell's tech support (Dell-Cares). They won't be able to help in any way. I had an extensive discussion with them which lead to the conclusion that the BIOS update causing CPU overheating/thermal throttling is a feature in the design...they expect it to happen, it is within the safe parameters they established.
I don't buy that and I said it to them, but to no avail.
My suggestion for anyone out there who is facing this problem is to install/run Dell Power Manager software and set it to "Quiet" or "Cool" on the Thermal Management tab. Both options will power throttle the CPU so the clock frequency will not max out, preventing it from thermal throttle.
I tried to explain to the tech support that the bios update removed from us the ability to undervolt the CPU via Intel XTU, which allowed to prevent thermal throttling without loosing performance. All they could say was that they were sorry.
Blame Intel, not Dell.
This is to patch a security loophole nicknamed Plundervolt. An attacker can potentially undervolt just enough to cause some internal CPU security measures to malfunction and allow access to secure areas.
The "fix" is to disable voltage control altogether.
