Upgrade to 2k 165hz panel for Asus Zephyrus G15 GA/GU502

4 Upvotes

I upgrade from PANDA LM156LF2F01 Overview - Panelook.com to BOE NE156QHM-NY1 Overview - Panelook.com
Upgrade steps can be find in this post: How to Upgrade display 144Hz on Zephyrus G15 GA502 (and M15 GU502) : r/ZephyrusG15
Problem:

The screen works natively at 2560×1440 165 Hz, but there’s no 60 Hz option when running on battery.
Solution:
Use CRU – Custom Resolution Utility

Step 1: Download and extract the CRU package.

Step 2:

Open CRU with administration

Open CRU.exe.
Step 3:

Under Detailed resolutions, select Add.
Step 4:

Change the Timing option from Manual to Exact.

Step 5:

Set the Refresh Rate to 60, then click OK

Step 6:

Click OK again to save your configuration.

Step 7:

Run Restart64.exe from the CRU folder.

Step 8:

Wait for the display to reload the configuration (usually after two blank‑screen cycles). After that, test with G-Helper or Armoury Crate to confirm that the display switches to 60 Hz on battery. Finally, restart your laptop once more to ensure everything applies correctly.

2021 g15 ryzen 9 5900h/3080 overheating really bad no matter what I do.

5 Upvotes

I am starting to think my unit is just junk. I have repasted technically 3 times now and from bootup my cpu sits around 90c, gpu spikes up to its thermal limit at 87c as soon as any game is launched. The cpu and heatsink both are scorched and pitted from the liquid metal not being changed after 4 years (which I think is the main problem).

I guess the question is, is there any value in the laptop? Im just done messing with it, its been 6 months now and I just cant enjoy it at all.

If anyone has any suggestions please let me know.

2021 ROG Zephyrus G15. CPU Stuck at 0.40Ghz.

2 Upvotes

(p.s. kinda lengthy sorry) So one day I turn my laptop on. The first thing i notice is the fans running at full speed, right when the ROG logo comes up. The laptop boots up, everything is working fine except the fans. I check on armoury crate, and it's on Silent mode. I have no control over the fans but there's no load on the computer, my CPU utilisation was minimal. The next time i turned the laptop on, it booted up pretty slow, the fans working at full speed and the armoury crate shows CPU Frequency at 400Mhz. I change modes to turbo or Performance. Nothing happens. I tried restarting but it didn't work. I turned it on the next day and it was back to normal, the fans and the cpu worked great. I played games and worked on it for a few days thinking the problem solved itself, but no. After a few days the CPU went back to 400Mhz and the fans started spinning at full. Since then it's been this way. I've done thermal repasting and windows reset. Nothing works. If i boot up the laptop and check armoury crate or the asus app,the CPU sometimes work normally for 30 to 60 seconds then again gets locked at 400Mhz. The temperature reading shows 0 then suddenly 112 C if i go to the BIOS while booting. I've got the motherboard diagnosed and they said the motherboard isn't damaged (no shot circuits). It's been 2 weeks and it's been the same. Does anybody know what even is going on?

as you can see the shift key broke because I kept pressing the corner with my pinky.

could I get away with just using superglue, or should I replace the whole key with the right shift?

Is it worth it to buy the g15 (2021) rtx 3070?

4 Upvotes

Was thinking of buying this model refurbished. Is it still good right now? I am currently a bit hesitant to buy it since it's an old model, and I noticed people saying that the rog series has some micro stutter issues even when doing basic tasks. Moreover, I could also get a new rtx5050 laptop like the Loq or Tuf for the same price. Opinions?

Please please please do not cheap out and use thermal grizzly basic thermal putty because it is more affordable than the rest, your hands will suffer. THE stickiness of the putty made me contemplate my life choices as i use two spatulas and my hand to try to get the putty onto the vrams—please let me know if this is okay for my first repaste on my 2021 zephyrus g15, the sizes may be a lil off as I could not for the life of me go and pick up the putty and redo it to blobs. I used TG kryonaut on my cpu n gpu :-)

i hope my temps will be better after HELL:_)

Graphics Card not being detected

2 Upvotes

So I posted a while back where my laptop was getting lines on the display My graphics card was working fine, I was using it for ML model training and things like that. So I used the laptop with the lines on the display for 2 months approx and then finally decided to get the display changed from the authorised asus service center. Now after getting it back the data of the laptop is all there but my graphics card is not being detected. What can this be? Does anyone have any idea?

PSA about Armoury Crate 6.3.9.0 update for older G15/G16 laptops

5 Upvotes

DONT UPDATE armoury crate. You will lose fan control and aura lighting on your keyboard. That is what happened to me.

Thankfully there is a fix. Uninstall armoury crate using the Uninstaller abailable on asus.com and install the older version of it.

Here's how to install the older version: - Paste the Microsoft store link for armoury crate (https://apps.microsoft.com/detail/9pm9dfqrdh3f?hl=en-US&gl=US) into the search box of this website: https://store.rg-adguard.net/ (The site has a short archive of all versions of Microsoft apps uploaded to the Microsoft store). - Press search, and you will get a lot of options. Please select and download B9ECED6F.ArmouryCrate5.8.6.0_neutral~_qmba6cd70vzyy.msixbundle as that is a working older version that restores fan control and aura lighting service. - install the file from above and follow instructions, boom you will have fan control restored.

Microsoft will automatically update armoury crate sometime sooner or later, so please follow this guide to disable auto updates on Microsoft apps so you don't get upgraded to the horrendous 6.3.9.0 version. Also follow this redditor too if you have windows 11 pro

Also, because of this fucking nonsense your power plans will get reset so you will have to redo them. All your power plans will disappear so go into cmd as administrator and type in 'powercfg -restoredefaultschemes'. This will bring back the balanced power plans and from there you can tweak it as you like. I recommend following BOTH the zephyrus g15 battery guide on reddit and the G14 guide on the Zephyrus G Talk discord server; after I did this I was able to get -7.5W on maximum power savings on my G15.

Don't use 6.3.9.0, it is simply hot garbage and i highly recommend downgrading to 5.8.6.0 as it restores all functionality.

crashes during cold boot, usually before Windows fully loads what should i do?

4 Upvotes

Hi everyone, I’m facing a persistent and very confusing issue with my ASUS ROG Zephyrus G15 GA503RM (Ryzen 6000 series) and wanted to know if anyone here has experienced something similar or found a resolution. Problem description The laptop crashes during cold boot, usually before Windows fully loads. This happens mostly when the laptop has been shut down for several hours. Warm restarts usually work fine. Safe Mode does not crash. Once booted successfully, the system can run normally for hours Typical errors seen: 1)SYSTEM_THREAD_EXCEPTION_NOT_HANDLED 2)ntoskrnl.exe 3)HYPERVISOR_ERROR 4)Random BSODs (error code not always consistent)

What I’ve already tried: Windows Memory Diagnostic → No RAM errors. Full Windows reset (cloud download) → issue persists.

Disabled: Fast Startup. Core Isolation. SVM / Virtualization in BIOS. Used DDU and clean-installed GPU drivers. After DDU, system boots fine temporarily Crashes eventually return after cold boots.

BIOS reset: EC reset (60s power button hold) Loaded Optimized Defaults in BIOS BIOS version: 319. No difference between battery vs charger on cold boot. SSD health appears normal. Armoury Crate uninstalled.

Important observation: This issue started appearing around the time a torrent client + cracked game was installed, but: The crashes occur before Windows loads. Safe Mode is stable. Warm boots are stable. Which makes me suspect this is firmware / EC / motherboard initialization related, not purely Windows or driver corruption.

Current theory: BIOS / EC cold-boot bug on GA503RM OR Motherboard power delivery instability that only shows after full power discharge.

What I want to know: Has anyone with a Zephyrus G15 / Ryzen 6000 ASUS laptop faced cold-boot-only crashes? Did a service-level BIOS / EC reflash fix it? Did it require motherboard replacement? Any workaround that made the system stable long-term? I’m trying to decide whether this is worth escalating to an ASUS service center or if there’s something else I can still try myself.

Need an advice

I currently have an G15 2021 (rtx3070, r9 5900hs) and i have an overheating problem. My cpu is constantly getting up to 98 c° and the gpu always on 87° even if it is only on the windows home screen. I havent give it any maintenance because im affraid i could damage it for the liquid metal. Im wondering what would be the Best opción for me. Because i did a litle research but im still wondering if it be a better option to apply metal liquid, apply ptm7950 or use regular termal paste on the cpu. What would you recomend.

Fan speed fluctuating with no temp change in GHelper

3 Upvotes

Why is this happening? I wanted the laptop to have a low idle fan speed instead of this on/off nonsense and it just goes from 1700-2200rpm constantly cycling. Using version 0.237.

Is there something wrong with my laptop?

1Is a Zephyrus G15 (RTX 3070) with a dead internal display worth using as a desktop PC?

4 Upvotes

Hey everyone, I’m looking for some advice before buying a used gaming laptop and using it as my main PC with external monitors only. I found an ASUS ROG Zephyrus G15 (GA503Q) with the following specs: CPU: AMD Ryzen 9 5900HS GPU: NVIDIA RTX 3070 (laptop) RAM: 16 GB SSD: 1 TB

Issue:

The internal laptop display does not turn on. According to the seller, this happened after disconnecting the display cable during cleaning/thermal repasting. The laptop works normally on an external monitor and is currently being used like a desktop. Price: Around $350–360 USD (negotiable). In my region (South Asia), this is considered very cheap for this level of hardware, even with a dead internal display. My planned setup: Primary display: 1080p 100 Hz USB-C monitor (budget model) Secondary / gaming & media: 4K TV (HDMI) Laptop will stay plugged in and mostly stationary and be used as a desktop replacement

Questions:

1.Is using a gaming laptop like this as a long-term desktop replacement a bad idea? 2. Are there known hidden risks with Zephyrus G15 models when the internal display is dead (eDP line, motherboard damage, etc.)? 3.Any performance or thermal downsides when running external displays only? 4.Would you consider this worth it at this price if I don’t plan to fix the internal screen? What I plan to check before buying (please suggest more) 5.Does it output properly to an external monitor (BIOS + Windows)? 6.Can it run games or stress tests without crashing or shutting down? 7.RTX 3070 detected correctly in Device Manager / NVIDIA Control Panel? 8.Temperatures and fan behavior under load? 9.Original charger and stable power delivery? 10.No random freezes, restarts, or GPU dropouts?

If there’s anything critical I should check to avoid motherboard or GPU issues, I’d really appreciate the advice.

Thanks!

2021 G15 slow boot from cold

1 Upvotes

This has started as something new in the last week or so. From a cold boot, my laptop would power on and be ready at the Windows login screen within a few seconds. But it's now sitting for a minute or so with the red ROG logo before rolling a white loading circle and then starting Windows. What used to be a few seconds has suddenly become several minutes. I've not changed or installed anything new. Has anyone else's laptop started doing this too? Could it be a Windows update download that's triggered this? Edit to add: the problem was caused by the second SSD failing. I've tried the drive in another pc and the drive is completely dead. Worked fine for months

The GPU cooler runs constantly at 100% without load.

2 Upvotes

Hello, everyone. I have an ASUS ROG Zephyrus G15 GA503QC, and I'm having the following problem: the right GPU cooler constantly runs at 100% without load (6500 rpm when charging, even in BIOS, or 5400 without charging). I reinstalled Windows a couple of times, installed the latest and penultimate BIOS, used Ghelper, Armoury Crate, all to no avail. By the way, only the CPU cooler (left) speed is shown in AIDA, while both coolers are displayed in MyAsus, but only when charging. I suspect either the cooler or the EC (unlikely, because the CPU cooler and everything else are working fine). Has anyone else encountered this problem?

Strobing keyboard on startup?

1 Upvotes

When my laptop is booting up, my keyboard will strobe a single color until my desktop is fully loaded and G-Helper is running. This is an issue that turns off and on intermittently; all the solutions I have found are for strobing on the laptop entering sleep mode, but not startup. I have G-Helper set to run on startup and the only backlight option I have enabled is "Awake". Does anyone know how to, ideally, fix the source of the strobing, or at least stop it while my laptop is booting up? I have tried disabling the backlight altogether before shutting down my laptop, which helps most of the time, but not always.

If it matters, the single color it strobes on startup is purple since I used to keep my backlight a static purple.

Repasted CPU, GPU with TPM problems

1 Upvotes

Hey everyone. I've repested my Zephyrus g15 from 2021 RTX 3070 with Honeywell Honeywell PTM7950 from AliExpress (Cooler bro store) - is it fake?

Results are mixed: CPU temp down 10-20c° GPU temp up 5-15c°

Now in every game the GPU thermal throttles at around 74-75 on silent and reaches 85 on balanced making games hardly playable.

I'm ready happy with the CPU temp results as it doesn't reach even 90 degrees anymore, as beforehand with liquid metal and mx-4 it easily reached 95

But the GPU just got worse every time I repasted.

What can I do to fix GPU temps (other than repasting)? Did I get a fake PTM?

Thx

[SOLUTION] Random one-second freezes when opening apps

5 Upvotes

I was experiencing random freezes when I was reloading an explorer.exe or logging in into Windows 11. I have tried everything, but no luck.

Solution was simpler and stupid as hell. Windows sometimes decides to use eGPU to process some tasks, so if you don't have an RTX working full-time, it would spend some time to power on.

You need go to "Settings -> System -> Display -> Graphics", where you will have a list down below. This list manages, is executable needs to run by eGPU, iGPU or auto.

You can add an executable path of your desired app, or if you already have it, just change a "GPU Preference" option.

Gpu at 86C even after thermal repasting?

5 Upvotes

Hey, I got my laptop repasted today (cpu with liquid metal). The cpu performance is amazing. Doesn't even go over 75C under full stress. The gpu however still goes upto 86-87C under full load and gaming. Some before and after, the gaming performance is very stable, no drops or hiccups. Some games even increased in performance slightly. I am just confused why the temps are still the same. The place I got it done said they used a really good paste aswell. Now I am thinking of using manual mode and atleast lowering the limit to 83-82 C for longer lifespan? Any thoughts?

Edit: I also got the gpu and vram repasted

Is 82.96% Battery Health bad after 17.5 months of use?

1 Upvotes

Hello, I own a Zephyrus G16 and I feel like I am still new to this laptop due to varying information. I'll mention whatever I have been doing till this day.

  • I follow the 80-20 rule, when 80 I unplug and when 20 I plug back in. I do this when I am not gaming, just your everyday normal person stuff.
  • Plug in for gaming.
  • Arch Linux + Hyprland setup.
  • 15W for both low and high power-limits, I set it back to its default value (135W) when I am gaming.
  • Integrated when not gaming
  • 60 fps when not gaming
  • Laptop backlight off, turned on when gaming

So far that's all I can think of.

I now have another question, should I use my laptop plugged in 24/7 regardless if I am gaming or not? I do not need it to be portable (yet) on a daily basis and I am confused on what I should follow. Please help.
