I am afraid that's clearly a firmware issue of your laptop. I believe you do not need to replace the motherboard but can just replace the bios will likely require an SPI flasher as there is little to no way to induce hardware failure by this.
However, Lenovo fixed my laptop by replacing a new motherboard for me. I don't know if there is a log for variables were removed. The boot disk is working now so if you can tell me the log location for that utility I can provide it to you. Yes, that will be best, as the utility has the same algorithm, and they should be able to reproduce the problem. AllowNvramReset is already off by default in the sample configuration, and making a consistent information message with any UI is uneasy.
In any case, I added a mention of both this problem and this issue in the documentation. It is a bug on latest ThinkPad firmwares, older versions have no issue with that. Good thing OscarXvita listed my guide where i got user reports for same issues. Lenovo ThinkPad TS with bios version 2.
No issues here. The log has been posted here.OpenCore - Configuring Auto-Boot on Startup
My best guess would be that the issue is cause by the deletion of the Microsoft variables. BIOS 1. I can confirm this as it happened to my Thinkpad E Can't seem to get bios file from their support website as its downloads are for windows only.
I guess that is the only option. Without knowing what exactly causes it we cannot file a workaround from our side. And then take note on the entry number of that boot option that you want to remove.
So you type. You will see that the first option is not available successfully removed and the second one is on first position. This way some of you can avoid bricking bios if the only purpose of reset nvram for your cases are to remove unwanted boot entries from bios boot menu.

The way OcSetNvramVariable works is that it attempts to read the variable.
Block can be used to delete the variable first in order to always force the Add value instead. I propose a third option. Why is this useful? Consider the following use case: We need some base set of boot-args to boot up OSX. So we add them with Add. Okay, so what if we just don't put boot-args into the config. That works, except if we require certain boot-args to boot, then forgetting to append them will make the system unbootable even more painful if the vault is used.
So ideally, we can use OC's "erase nvram" option to wipe all the variables and then reset them with a clean default. A second use case: csr-active-config is used for SIP. OSX does the checks to make sure csr-active-config is only modified in recovery OS. However, setting it in recovery OS still doesn't work if there is already an Add entry. Given the above, I do not see an issue or the need to change anything.
The logic looks perfectly natural to me. That's a good point, should really implement them as IGPU properties. Could you submit a bugreport please? I believe macOS firstly deletes variables. Or my firmware is non-conformant, as we tested the behaviour above and it worked. We could consider some routes to fix this in case it causes problems. One of them is to make FwRuntimeServices. Download-Fritzwhat do you think about it? If you "fix" it in FwRuntimeServices, it will explicitly violate the spec.
On the other hand, I don't see a good point for the specified behaviour either except as some sort of request sanitizing, imo wait for what osy86 has to report later.
In this case I do not mind ignoring the spec and incorporating the following change in SetVariable wrapper of FwRuntimeServices. From what I remember SIP does affect boot-args. You cannot e. I do not know how it is now, but it should be like just -v or such. So creating a new variable still works. Setting a variable already marked NV I used "prev-lang:kbd" still works. It seems only previously volatile variables now trigger that error instead of silently failing to change attribute.
That's strange to me. But in that case, I should have seen an error message before. Variables in Apple Boot namespace, i. Well, at least were :D.

I really like that I have an assigned agent for my trip booked with Nordic Visitor. As our plane arrived late at Copenhagen airport, I didn't see the limousine drive holding a sign with my name and got worried.
I sent an email to my agent, and was informed right away that she had called the limousine service and told me the exact location the drive was waiting. I found the driver and started to relax and enjoy my first trip to Scandinavia. The upgrade to the first class train ride from Stockholm to Copenhagen really enhanced the journey. The detailed itineraries reminded us things to do and suggested attractions to visit.
The overall experience with Nordic Visitor is simply awesome. Everything about our trip was perfect. Our guesthouses were exceptional. Maria went above and beyond for us. Thank you so much. Overall the trip was terrific and Hanna specially was exceptional.

Everything that was provided was very detailed and top notch. She was also very patient with all our questions and changes that we requested. I would highly recommend Nordic Visitor and Hanna would be our go to person on any future trips. I have already recommended Nordic Visitor to all my friends, family and colleagues. Our flight departure was delayed an entire day and we were concerned about losing out on our first day activity, airport transportation and accommodation.
He went above and beyond to ensure we were taken care of, especially after the stress of being a day behind on our ring road trip. I would highly recommend him, thank you for all your support. You made our trip and scheduling as effortless as possible. We are still talking about our experience to everyone who will listen. We have been to Iceland two previous times (in November) but this time we wanted to experience springtime in Iceland.
It exceeded our expectations, and as we were already in love with your country that was hard to do. Everyone was so helpful and friendly, as first time travelers of the ring road your organization set up our itinerary so that we didn't have to worry about a thing except having fun. All the hotels and sights to see were planned out on our map and in our travel guide book, anything we needed to know was in our packet.
Something that was out of your control but played an important part in our unforgettable adventure was that the weather was sunny and warm everyday. We have experienced Iceland in all types of weather and it didn't stop us from enjoying ourselves immensely but the sunshine was an added bonus.
Very quick to answer all of my questions with friendly informative replies Choices of varied accommodation was wonderful - loved the guesthouses. Daily driving time was perfect between destinations- not too long or too short. Excellent planning - well done. We had a wonderful time. Our accommodations were very good and loved the wonderful breakfast every morning. We didn't feel rushed and people were so willing to help us and give us advice. We greatly enjoyed the tour and have specifically recommended it to friends already (to see if they want to join us for another one.
I've already recommended Nordic Visitor to two friends.Then simply fill in all the details you want it to remember about you, eg, name, address, postcode, date of birth.
When you see a form you want to fill in, click the Roboform icon and select your identity. This will magically fill in the blanks with your details (do double-check though). Roboform can also remember user IDs and passwords.
You can automate that phrase using a bit of free software called AutoHotKey. Then all you have to do every time you want to enter, say, the first line of your address, is press 'Alt' and '4', and like magic the words '29 Acacia Road' appear in the form.
To do this, you need to write a 'script', a plain text file with personalised instructions for the program. This sounds uber-nerdy, but it's actually pretty simple. Once you've installed AutoHotKey, open a basic plain text file in Notepad. Huge thanks to VelvetGlove for writing this script.
Each line in the file creates a different action. For example putting '. Once the plain text file is edited, save it on your desktop, and be sure to end the file name with. In the 'Save as type' box, you must select 'All files', or it won't work. Now it's time to run the file. Find your personalised file on the desktop, and double-click on it to make it run.
Then find the AutoHotKey icon on your toolbar, right-click it, and press 'Reload this script'. You can now use the shortcuts. Once the file's up and running, it can be edited at any time. Just find it on your desktop and right-click on it to edit the script. After it's saved, right-click on the AutoHotKey tool bar icon and select 'Reload this script'. This will make the changes.
