Dear community,
I am not very well versed with the technicalities unlike many of you and hence seeking advice.
I have a thinkpad T490 laptop for personal use which has lenovo vantage installed on it. Every now and then, the system asks me to run a few system updates like "thinkpad bios update - 10 64" or "intel management engine firmware - 10 64".
When I run the updates, at the very end, it asks me:
Before continuing, please confirm the following
confirm "intel management engine components" is installed in your system
Please see attached for the full notification.
I really do not know the answer to this question so I always cancel the update. Please can you help?
I'm trying to help a friend out.
Anyone know what kind of engine management system a 2007 Honda shadow 750 has? Ex speed density, mass airflow, Alpha-N...carburetor?
I have the know how to tune, just need know the what.
After reading a lot of interesting articles, it seems very likely that more devices could be compromised. What about companies like Broadcom, Qualcomm, Nvidia, ARM et al?
Is any device we purchase (general purpose CPU, mobile CPU, GPU, router chip etc) a potential privacy risk? Especially for routers is it the same amount of pointless that even if you install OpenWrt for example a hidden co-processor could still monitor all your data?
Also, I imagine Cortex-A chips having something similar as it presents a very tantalizing target but I suppose that Cortex-M doesn't have anything like it right?
P.S. Is the only solution to get a Libreboot computer?
Basically, a wave of posts are coming in, but it isn't the majority of users. It is, however, a large amount of folks who are reporting the issues. These issues are the manifestation of over-saturated memory buffers, more than likely, which suffer due to latency between CPU, GPU's VRAM, and the RAM itself.
Hardware, when overclocked or not, should be perfectly capable of handling the workload of a program without significant issues. However, there is some error or glitch within Warzone's current build that is putting too much load through too small of a channel within the pipeline of the three main components. Complicating things further, CPUs have their own cache memory. Who knows how the game is utilizing that, but these things should be looked into ASAP.
To be clear: This is not a hardware issue, this is a game issue. You may have hardware issues that are aggravated by this game issue, which is a symptom.
The game's issue is just affecting sub-optimal hardware configurations the most, which honestly is interesting, as it presents an opportunity to learn about our machines and set them up properly to get the most performance out of them.
Basically, the less stable and optimal the settings of any given piece of hardware, the worse this issue presents itself; People who have garbage memory timings will have hitching/stuttering. Frame times above 1000ms. People with non-overclocked CPUs and slow memory will definitely have this issue.
This is not a narrative. This is a report of a problem within the game with an intriguing side-effect. Thank you for your time.
Edit(Post Season 4 launch): These issues have been somewhat addressed in the update, but the problem persists for many users, even those above required/recommended specs.
Edit 2: Several of you have messaged me on reddit, and I really appreciate you reaching out to me. I've been able to solve most of the issues for people, and where I wasn't able to do so, it was because the other person just gave up. If you find this thread somehow and need assistance, message me here on reddit. The issues you're having can absolutely be figured out and fixed, it just may take a bit of time and learning how to do certain things on PC you didn't know beforehand.
Also, the most common solutions so far have been:
-Dirty/Old Operating Systems, where reinstalling Windows fresh was all that was needed; Only recommended if you're running an installation of Windows at least 3 years old and has seen heavy use
... keep reading on reddit ➡I am planning to buy Bonobo WS model laptop from system 76. When I heard about the coreboot and Intel Management engine disabled by default and take a look on their website. Do all of their system comes that way ???
Hey! Welcome to my dilemma. Hope you can help but if not appreciate you looking out to help me. So here goes.
I am in a position where I have to choose between Software engineering, Systems engineering and Project management as a path to develop in. I am software engineer but have always thought I will have to transition into a senior management type role as I further my career because I will get bored of code and burnout with tech if I don't have other people related tasks. Now I have not been working for a couple years and it's been quite slow so I enjoy programming and look forward to it but idk how long will it last.
I think I have some idea of each role but I want to hear second perspective on these roles and their longevity and demand.
Other than that I have a few questions too:
- How do these roles stack up in hierarchy? As in who talks to who, answers to who, and then how are they valued in the organization?
- How is each role viewed in the industry and how much is each's pay grade?
- How crucially is the responsibility of each role viewed in an organization?
I know it is a lot of questions but I have been trying to find information and just thought maybe reddit can help. If you can answer any questions, I would really appreciate your input. Thanks!
Cheers!
Vendors basically push their design solutions and frankly the lack of expertise among our engineering departments leaves them with no major alternatives besides historical reliance on the relationship with said vendors. Basically no one even questions SEL or Emerson or Scheider , Rockwell etc; they can sell shit in a box at this point and no one will question them. It's a matter of time not if when something major happens because no one diversified their OEMs usage.. Not to mention they have us by the balls because a lot of equipment isnt interoperable with other vendors so we have to keep expanding with the same vendor.
what are your thoughts?
Hi all,
Yesterday I started my car and got an anti-pollution fault message, followed by an Engine System Faulty message. Since then I’ve not had the anti-pollution one, but the engine message shows every time I start the car. The master warning light comes on as well (triangle with exclamation mark). I have not noticed a difference to the way the car drives but I will be taking it to a garage soon. I was hoping maybe someone here may have had this problem before and could clue me on what the issue might be. Worth mentioning that on a few occasions very recently I had a low oil pressure warning as well. The coolant has been heating up and going over 90 C pretty quickly as well recently.
It’s a Peugeot 207 1.4 2006 Sport. Please let me know if you have any ideas, thanks a lot!
I've never had a car turned or modified and I'm more of a "keep it stock" kind of person.
I'm looking for information on whether it's worth the cost to get a new engine management system for my car. It's all stock. I'm not looking for more power, necessarily, but longevity and perhaps better fuel economy. I want this engine to last as long as possible. I figured, since this cars systems are 30 years old, that new systems might help make everything better.
Would it's stock form be the best choice for reliability/longevity or are there better options available and would it be worth the cost vs just doing an engine rebuild when the time comes?

I downloaded the Intel® Converged Security and Management Engine (Intel® CSME) Detection Tool to check my Matebook 13 (2019). I updated the Intel ME driver and firmware to the latest versions from Huawei support web page, but it still reports the system as vulnerable.
Do the cars use a single oxygen sensor in the turbo downpipe? Do they have two oxygen sensors, one for both banks of cylinders? Is there a sensor for each cylinder?
Modern 4 cylinder road cars can use a single upstream oxygen sensor to calculate an individual cylinder's air/fuel ratio. 6, 8, 10, and 12 cylinder cars can do the same with two upstream sensors. One for each bank. Do F1 cars use anything like that?
What about ignition systems? Do F1 cars use compression sense ignition? General Motors used compression sense ignition in the past to generate a faux camshaft position signal, but it can also be used to calculate cylinder contribution. Does anyone know of F1 cars use anything like that?
Do you own a 2005-2016 GM LS/LT engine with Active Fuel Management (AFM) that has noisy lifters? We are testing a solution to reduce the "typewriter tick" noise that will not void your warranty or disable AFM.
Signup below to become a tester of an oil additive to resolve noisy LS/LT engine lifters.
I was looking at a diagram of what's inside a typical engine management system for a typical car, and it looks like this. I immediately thought hey, Arduino has all this. Why couldn't I use one to make an EMS from scratch?
I realize the programming would be pretty intense, but I'm not too worried about that. My programming skills are way better than my Electronics skills.
