This is a shot in the dark, but since the Razer Blade switches from active (fan) cooling to passive (thermal) cooling when switching to battery, the BIOS may have additional thermal safeguards on battery to keep ahead of temperature runaway while relying solely on passive cooling.

EDIT:
Can someone confirm these numbers look good, this is with the settings from the first post.

Also people who apply liquid metal as a thermal conductor often put electrical tape around the die, which may cover sensors around the CPU resulting in faulty readouts such as this.

Tried flashing BIOS twice after modding and even though in the original BIOS settings were chanegd and I see it changed after I open it with AFUWINGUI it doesn't change the BIOS. Any ideas?

So don't use the settings as the OP if you have a 9750H. My laptop somehow turned on by itself and was heating up in my backpack on its own. System got so hot that screen was blank and too hot to touch.

Are there any modified BIOS' out there for the new Blade Stealth with 1650 that unlock some additional options?

No clue what changed but now my laptop is running 60-65c when plugged in and a little cooler when unplugged. Like the CPU isn't stepping down or something, not sure. Battery life has gone from 4-5 hours down to about 2 hours. Definitely shouldn't be running this hot when idling and undervolting by a bit. Was fine for a few weeks.

I am planning on doing this on my Razer Blade Stealth 13" late 2019. What should I do differently from the OP? Tips before I start? As far as I understand the only real difference should be the IMON values or am I wrong?

I modded the file according to this thread. Was there any difference between them?
I have gone through the whole guide and can change options in bios. They are just under slightly different titles. -

Hi Guys,
New to this so please bear with me!
I have the RBS13 late 2019 - When the dGPU is enabled, the processor is limited to 15W, when it is disabled the processor limit rises to 25W.
I assume that this change is controlled by Razer Synapse?
What I want to achieve is perhaps a 20W limit when the dGPU is enabled, instead of 15W - I believe this will be a suitable compromise. So I have some questions:
1. What exactly do these do? I understand they set up new Windows power plans, but what is the difference in each?
2. Would I be correct in thinking that OP effectively removed the power limit, so the system relies on other things like temperature and frequency limits to safeguard?
3a. Would it be feasible to simply leave the IMON slope at default, and use an IMON offset of -5000 (5W)?
3b. Would this also mean that when the dGPU is disabled, the processor limit would inadvertently rise to 30W?
4a. If I uninstall Razer Synapse, will the power still limit in the same way?
4b. Does changing the IMON offset have an effect on things like battery life estimates and other power readings?
Sorry if any of these questions are in the thread already - I had a good read and still couldn't answer them so hopefully I'm not just being slow.
I appreciate your time,[/QUOTE]Last edited: Mar 30, 2020 -
One approach that may be more in line with what you want is to leave the IMON offset at default, and then change the IMON slope to 50. This way the reported power should be exactly 1/2 of the actual power. (You could do some other value, but 50 makes the math really easy).
Then use something like throttlestop to limit power. So if you want 20W actual, set the limit in throttlestop to 10W. Then the limit is always 20W actual (with or without the dGPU active), until you change the setting in throttlestop.
Alternatively, you could set the IMON slope to 0.75 and not set a limit in throttlestop. Then when the computer thinks it's at 15W, it'll actually be at 20W. With the dGPU off, the CPU will think it's running at up to 25W but in reality it'll be running at up to 33W. -
Also, why do you suggest changing the IMON slope, and not the offset? -
As for adjusting the IMON slope but not the offset - they both adjust power reported, in different ways. Power reported = (real power * IMON slope/100) + IMON offset/1000. So you could adjust either or both to get where you want to be. For example, you could leave slope at default and make the offset - 5000.
Edit: to be clear, when I say it can still thermal throttle, I mean that I have tested with this specific configuration (just the change in IMON slope, none of the other changes listed to windows or IMON offset or any of that). The first thermal throttling mode that you'll run into where it ramps down the power limit still works - it'll just keep lowering the power limit until it gets the temperature down. Being off by 50% doesn't prevent that.
I suspect that there's also other throttling modes (like reducing the maximum frequency), but I'm not going to test that.
Then of course if everything goes horribly wrong and none of that works properly, it should still be able to shut itself down as a final safety measure.Last edited: Apr 1, 2020BartusCompater likes this. -
Hard BSOD after I made BIOS settings at 9750H any ideas?

Hey guys, what would be the recommended IMON settings for the RBS 13” with 1650 dgpu? CPUZ is showing 15w with and without enabling DGPU, so I’m not sure where can I verify the current wattage and if changes are reflecting. Thanks for help

Thanks, however i'm getting higher Passmark scores on stock FW compared to the modded one based on the recommendations, around 10% less...can't get my head around this...This is on late 2019 RBS 13" with 1650

Hello everyone,
I just tried doing this on a 2019 version, RTX 2080 (+ 32 GB ram and +2 TB Intel NVMe, if it matters somehow) and no matter what, the CPU VR menu doesn't show up.
I'm not even posting pictures or anything because it looks just like in the uploaded screenshots, but yet, they don't show when I reboot.
I'm attaching the modded bios just in case someone wants to have a look at it.
Did this happen to anyone else? Can anyone help with that?
Thanks.Last edited: May 7, 2020 -

Hey. I bricked my blade doing this a while back (I wasn’t following this specific guide, I stupidly downloaded a custom bios from a Razer blade 2017 ultimate optimisation guide that was pinned on the Razer Reddit page) and I’ve been wondering how I’d go about removing the brick, could you possibly help me out or point me in the right direction?
Razer have told me it will cost £1000 to fix.. -
I've mentioned the tool here: http://forum.notebookreview.com/thr...ll-hidden-options.830993/page-9#post-10980631. Using this, you'll be able to flash a fresh and correct BIOS to the BIOS chip on the motherboard (of course only the right region, the one you overwrote back when you bricked the device), which should get the machine going again if it all works out. -
-
So if you're actually at 60w, it'll think it's 30. That means that on, say, balanced mode with a 35W limit, you can actually run at 70W (assuming cooling keeps up).
That being said - I've only tried this on a blade stealth, where only adjusting the IMON slope works just fine.BartusCompater and amihail91 like this.
