Absurd 2025 Scar 18 G835LW Issues

Level 7

I can't figure out with this is a PSU or temperature issue.  I've reached out to ASUS about this and they're absolutely no help at all.  They want to troubleshoot by resetting everything to factory or factory resetting default hardware settings and I'm just over it.

CPU idle temps are about 60-71 degrees.  Under heavy load are 95-100+, under medium load is still about 95 degrees.  This is a brand new laptop released in May 2025.  GPU temps are also hitting 85 degrees pretty regularly, I'm unsure if this is standard.  ASUS customer support is not capable of providing information on whether or not this is expected.  Is this normal?

The laptop keyboard will sometimes stop responding for upwards of 60 seconds.  It regularly powers off now.  I can consistently shut the entire laptop off by performing an auto-detect settings in Borderlands 4.

Call of Duty Black Ops 7 causes shut downs constantly.  Event Viewer reports a BSOD but nothing I can make sense of.  I changed from Performance mode to Turbo and there are no improvements.  It maybe lasts longer before it turns off, but that's about it.

These laptops are far too expensive to be running like dogwater, and I'm passed the return period.  ASUS has suggesting I can RMA this POS but if I do that I'm without it for upwards of over a month's time with the possibility that they will send it back to me if they can't replicate the problem.  I am absolutely chapped abou this, and want to know if anyone else has been running into any of these same issues with their Scar 18 and if they ever did find a solution?

That was me, posted under the wrong account.  You can search and see all the posts I have made about my problems with two different laptops.

You may not want to hear this...

 

I have the G835LX and I have the EXACT same issues.  Exactly.  Temps running really hot under a normal load..  They idle around 97-99 running a heavy load and reaching up to 103 off and on.  I measure it using both AC and MSI Afterburner.  Although it will run BO6 ok it crashes with Dune Awakening, Once Human, several times with BF6, No Man's Sky (released in 2016) as well as other games.  Screen goes black, sometimes I can still hear the game sounds, laptop restarts OR I have to hold down the power button for a hard reboot.  Event Viewer had 34 Critical Errors (when it crashes) and all of them said something to the fact that the laptop didnt shut down properly, lost power ect.

LONG story short, I have dealt with ASUS customer support before and their turn around is really slow.  I asked if there was any other options and she told me to take it back to BestBuy and they can send it in saving me all the BS hassle.  I did this.  TWICE.  The first time they kept it for two weeks (well they sent it off) and when I got it back the first time they said that where ever they sent it redid the thermal paste, something to that effect and replaced the motherboard.  I immediately test it at home (Best Buy demanded I sign a waiver saying it was fixed.  BS, I took it) as everything had to be added back...STEAM, games, Afterburner ect.  Well there was ZERO change.  NONE.  I take it back to BB and they send it in again.  This time 3 week turnaround.  I get it back, they again want me to sig a waiver, threatened not to give it back.  Talked to manager and said I wasn't signing sht..They said this time they replaced the internal battery and fans.  Take it home and again ZERO change (BTW both times they claim it passed their tests).  This time I cave in and go through the absolute pain in the butt RMA nonsense.  I have to box it up, print sht out and take it to FedEx.  I use their laptop box that is padded.  After a week of checking the updates from it saying they are repairing it, it changes and now says they sent it in for an internal review.  I finally have to call, pain in the butt, and they say it was damaged in shipment.  They send pics and sure enough one side is ripped off.  They were nice and made a claim on my behalf through FedEx.  FedEx immediately takes responsibility.  Finally work begins.  Now a month later I get it back.  They said they redid the thermal paste. Temps are now sitting around 80C under heavy loads.  Whatever they did fixed the temp problem.  Did that solve my crashing, fuzzy screen/SUPER bright screen, constant critical errors, keyboard RGB constantly going out, restarting while im sitting here doing nothing....F no.  It is in the same exact condition minus stupid hot temps.  

There is a lot more to it, a LOT, but in the end it is pretty much what you have going on.  I have wasted literally 4 months on this POS.  I have done everything.  I have tired everything...BIOS, restore points, factory restore, entire drive clean, updates, drivers, deleting AC, watched every vid on YouTube ect.  I've been doing this PC gaming thing since 1997. I'm a playtester for many AAA games, including BF6, I know what I am doing.  I can't figure it out.  They cant figure it out after three attempts.  They aren't about to switch the ****** thing out. There is nothing more I can do.  I've washed my hands of the whole thing and went a different direction/brand.  I've never experienced a total lack of communication and uncaring service.  There is a lot more I could add but you get the idea. If you have any questions feel free to ask and I truly wish you the best. I wouldn't want anyone to go through that. 



That sounds like last time you send it they did a proper LM respread plus lowering the max Frequencies of Core and the Cache in your case. Maybe there is something deeper in your case we couldn't know without deep inspection but I'd just go and guess inadequately tested faulty BIOS from Asus was and is your problem.

It screams "I want a Liquid Metal respread". They already come from factory with badly spread LM. And with so little time they oxidize. You don't need to buy anything. Just open it descrew heatsink, respread it with a quailty cotton swab. MAKE SURE YOU DONT DROP *ANY* TO THE MOTHERBOARD. Go look up for a guide. Respread of LM is your only solution dont look for any other one. If you dont feel brave or in your country repasting breaks the warranty of the laptop send it to ASUS for cleaning and repasting. 

After you are done with a good LM respread you won't believe the temp differences. Though you wont get any heat throttling from that point you will get power throttled mostly because ASUS dont care about us and put prison like power headroom for all intel cpu BIOSes since 2023-2024.

Do you have any proof of what you are saying about the liquid metal being badly applied in the factory?

Because if after it was assembled, tested, used, gone through heat cycles, transported... there is no way you would know this by opening the laptop and removing the heatsink. What you would be looking at is more likely the result of the liquid metal moving due to other factors like the pump out effect. 

As to power throttling that also depends on what you mean. All laptops will have a power share going on between the GPU and CPU, with the GPU taking priority. So if you play a game the CPU will hit the EDP limit set by the BIOS which is usually somewhere around 65W to 85W depending on CPU and model. For example a 240W PSU would typically allow 175W for the GPU and 65W for the CPU when under a high load, but this does not factor in other power draws, like USB devices, motherboard components, nvme... lights... screen...

Anyway, I'm not attempting to downplay any genuine concerns but there needs to be some thought into making a point other than a statement with no factual basis or explanation to it. So in order to get some understanding are you able to provide more specific details about your issues or evidence?

1) Badly applied LM at the factory is a myth, anyone opening will just see a blob, dry spot and leaked LM on protective guard depending on when they took it apart (how new)

2) Your comment on power throttling makes no sense alone as this is normal behaviour. (Can you be more specific?)

About LM spread; you can just look up for posts ranting about how their newly bought Asus Laptops LM was not touching most of the GPU-CPU chips. There are bazillions of them in the internet.

Which was identical in my case. I bought the laptop only used it as a desktop never changed the horizontal state of it. CPU package was around 70-80C while idling. Opened it up respread the LMs booted and i was getting 30-40C Idle Package Temp in the same conditions with much less Fan RPM. These happened in the time span of the first month following me buying my ROG Strix Scar G834JY from ASUS. 

That's not just me hallucinating. Their LMs are not being carefully spreaded its shady work. 

About the power throttling i am really really at a point that i can't even compose one more sentence about it without puking. I will just link here one of the recent posts i made about it.

https://www.reddit.com/r/ASUS/comments/1p9mfs3/rog_strix_scar_g834jy_unbearable_input_lag/

If you have any expertise around the subject and have any guidance for me I am eager to listen. Just please don't claim it's normal behavior nonchalantly. I had many Laptops with less powerful specs than this one, which were getting insanely more performance and much less Input Lag. Also until the beginning of the 2024 (the time where a BIOS update was forced and broke my performance altogether) I was pretty much happy with the Laptop and getting good performance except some bearable firmware problems.

Lastly there is this post:

https://www.reddit.com/r/ASUSROG/comments/1nivf1v/asus_gaming_laptops_have_been_broken_since_2021_a/

; which even the ASUS accepted publicly and stated "they are working on it". Which I think will be to no avail, I have no more hope for ASUS high end Laptops anymore.

Per your #1 comment, I giggled. See my post above. The factory applied it. The company BestBuy sent it out to redid it. ASUS themselves had to redo it. That's a total of three times to get it right. 🤷

I agree that you can look at many posts of people complaining about the liquid metal but in essence that is all it is. Many videos exist and all are people making claims with no understanding of what they are looking at for the reasons I mentioned, that is you cannot remove the heatsink after multiple heat cycles and claim it was done poorly at the factory. If someone could actually show evidence I would accept this to be accurate but until then it's just a false statement.

The alternate explanation is more likely: Liquid metal is perfectly applied at the factory but due to transportation and the CPU die seal being excessively wide, under normal operation the liquid metal is pumping out and being exposed to air due to the large seal over the CPU. It also means if the laptop is dropped, bumped or subject to cargo load / drop shipping where it is exposed to extreme cold temperatures it can impact the liquid metal. This is a problem for liquid metal and one reason why hybrid variants exist but the seal on the CPU is another issue, it needs to be close to the die size to minimise oxidation and spillage / pump out. 

People do not factor this when taking their laptops apart or making videos, instead the mess they see is immediately blamed on poor application. I have taken my laptop apart, seen the mess and to me it is clearly the above. Furthermore I have then completely cleaned and reapplied new liquid metal, kept the laptop flat and took it apart 6 months later just to see the impact. The result was almost the same as it was when I got it from ASUS.

This is the ASUS application, laptop was 1 month old at the time.

Here is my application and inspection after 6 months.

Very similar in appearance and the dry spot is also important, this is directly above the P-Cores, so the CPU hotspot is another aspect to consider when looking at how it spread out over time. But the point I make here, I am fairly confident that all talk about liquid metal being poorly applied is a myth and only exists due to people jumping to conclusions. I conducted this investigation / experiment purely to see how it would hold up and to prove / disprove the liquid metal application. (Try for yourself and see if you maybe will change your point of view)

 

Power throttling is normal behaviour in a laptop, any default CPU will hit the limits almost constantly plus there is a reason why the specifications mention a dynamic power share between the CPU and GPU when both are under load. That is the GPU will take priority so a typical laptop under a gaming load may see the GPU at 175W but the CPU limited to 65/75/85W depending on model. What isn't normal is a laptop that was working, then due to a update or other underlying cause is now lagging and stuttering. If you are someone that had a working laptop, then something went wrong, fair enough but to make a generalised statement without any explanation is not a valid point because all laptops do power throttle and work fine without problems. 

Yeah I am not a physics expert. Shipping might have been the sole cause too for the bad state of these liquid metals. Though from the overall state of the liquid metal when I opened made me think application of it had a part of the blame too. There was so little to none on the chips. But it is not a matter of us to dispute over. Let's just say it had spilled and on a bad condition from other reasons. Even then a respread is imminent as the only solution.

About the power throttling we are discussing it on my post.
