Intel-TongFang QC7 (Element/Fusion 15/MAG-15/Vapor 15 Pro)

Does anyone have a solution to the trackpad? It seems really inconsistent when I need it the most... When I use it sometimes it randomly stop registering my touch (while on battery, no heat or anything) and then as I keep moving across the touchpad it starts acting as though I am using the 2 finger zoom gesture or scroll. I have to push the trackpad into the chassis a little in order for it to return to normal but it still acts weird again later...Is there a way to change trackpads? better drivers? any solution to this?

Edit: Reboot seems to fix the issue... not sure for how long, will keep testing and report back. I really hope it's a software bug and not a hardware one...

@Eluktronics Is the max 17 power brick compatible with the mag 15? and if so, can you post the dimensions of the power brick? or is it equivalent to the mag 15 "slim" adapter?

 

I have the exact same problem and I'm still tracking it down. I can 'instantly' fix it by putting my laptop to sleep and rewaking it from sleep, but it intermittently stops working. On mine it's allowing single finger tracking but only on the lower third/half of the trackpad and along the borders of the entire pad (save for the top middle). I've manually deleted the touchpad driver and had windows reinstall it, I've reinstalled Windows, etc. My latest experiment has been to delete the LG Hub software that I was using with my Lightspeed mouse (G703? I don't have it in front of me right now).

So far my touchpad has not wonked out on me since I uninstalled that driver, but I haven't had a ton of time to put it through its paces. I've been trying to bring this up here on the forums, but realized I only just registered so I had some sort of waiting period to post or reply.

But also thanks for all the help on this forum so far when it's come to installing the right nVidia driver to assist with the battery drain and other tips. Much appreciated!

 

From what I can gather from googling HRESET and results linked to Thunderbolt and USB-C, it's likely linked to the controller chipset for the port.
Found the following description for the HRESET I/O:

"Active high hardware reset input. Will reinitialize all device settings. Ground pin when HRESET functionality will not be used."​

So from what I can gather, they didn't have (or incorrectly implemented) a trigger for HRESET, which might be something required when a change or problem is detected in the connection/port and re-initialization is needed to update/resolve the connection. Hopefully this will resolve some of the problems some people have reported where the TB USB-C port wasn't working properly at times.

Or it's something completely different.

 

Not sure if it counts but the hang ups and lag issues seem to have stopped with the latest nvidia game drivers (including GeForce experience) and XMG control centre 2.1.0.19 after updating to BIOS 60. I'm using intel driver update service to keep the other drivers up to date. Had a quick test and games running stable with GPU @ around 1200mhz - will test this more later in a cooler room.

 

Hopefully this is the fix for the thunderbolt issue. Unfortunately I RMA'd my laptop 2 days ago so I don't have it to test!

 

Never mind - the touchpad still goes out without the Logitech Hub software running. *Sigh*

 

Tracking of trackpad is not the best, but I dont have any further issues with it.

 

I'll post them tomorrow, I believe there are some on page 66.

 

For fully compatible Power Supplies including correct 12.5mm plug dimensions, check out this list:

"unofficially" but they all would work on any tongfang chassis that uses the same 12.5mm length plug some with a 12.5mm length adapter, some without. This post uses the barrel diameter which will fit TF chassis.

The power supply unit that came with my machine is labelled FSP230-AJAN3 from "FSB Group Inc", and the not-much-smaller unit I bought from Eluktronics is ADP-230EB T from "Delta Electronics"

BTW guys, it looks like Intel-USB-C problems aren't limited to the QC7:

https://www.laptopmag.com/news/lenovo-thinkpads-hit-with-widespread-usb-c-port-defects-what-to-do

The scary part is that apparently the Intel-provided firmware will outright break the hardware (over time) after which it's too late for a software-only fix; according to:

https://www.notebookcheck.net/Think...t-s-happening-and-how-to-fix-it.451207.0.html

the potentially at-risk Thunderbolt controllers are:

----
Affected Alpine Ridge controllers (2016) PCI IDs: 15bf 15d9 15d2

Affected Titan Ridge controllers (2018) PCI IDs: 15eb
----

My QC7 is apparently 15e8 - I assume that applies to all of you, in which case it means that any Thunderbolt problems we might face are a different set of Intel-related problems?

 

I purchased the FSP180 180w charger from that list for day to day use and it's significantly lighter than the stock 230w charger. Obviously wouldn't work for full tilt gaming but I mainly use my laptop for ultrabook functions during the day.

 

Same here which is why i bought the lighter 230watt charger. But that new asus g14 would have been an even more perfect laptop since it supports type c 65w charging. A shame we cant do that with the mag.

 

Hi all,

does anyone know how many displays the QC7 can drive *simultaneously*? Is it possible to drive a monitor off the USB-C at the same time I am using the internal display *and* the HDMI (for a total of 3 displays)? Does anyone know of any USB-C or HDMI solutions that can drive more than one display at a time (I'm thinking of doing my own "home made" 4K solution by adding three 1920x1080 displays to the built-in display for a total 3840x2160 resolution when I'm set up on a desk - this would mean I'm one port short even if the USB-C and HDMI can be live simultaneously)

 

Usb c port should be able to support 2 display port 1.2 monitors at the same time with correct usb c to display port splitter.

thanks!!

I googled, I see what you mean - these splitters all seem to say the USB-C port needs to support "DisplayPort Alternate Mode", is this something the QC7 support? (sorry for all these basic questions)

Thanks again

 

Just finally got my Eluktronics, so far very good, really like the build quality. Questions: 1) do you recommend to update bios? (i have 2019.0808.1937 now) 2) which soft to use to do undervolting?
Thanks

 

Yes it does support display alt mode

Did I miss something? There seem to be no mainstream publication reviews of Mag or Max laptops. The Max versions are new, but Mag has been around a while. ????

 

Anyone here been able to use the Asus GPU Tweak to raise the gpu temp-limit? It doesnt seem to work on my unit.

Geforce 1660 ti
Nvidia Driver: 441.41
BIOS version: QCCFL357.0058.2019.1209.1324

EDIT. added laptop details

Did you even try?

 

So, I recently got a MAG-15 from Amazon, but I notice that the 2tb NVME inside it is very slow to access. There's a small "catch" when you go to do anything that might require disk access, and I was unable to turn-off Link State PWM in Intel RST (my understanding was that this was causing the SSD to spike to 100% in regular intervals). I went into the power plan itself to turn of Link State.

I guess my question is, do I have a bad SSD? Boot time is very slow, and these "hiccups" for lack of a better term are making me wonder if the problem is this off-brand "Eluktronic Pro" disk.

Edit: I re-loaded the OS clean on a spare 256GB NVME, and did not have this issue any longer. Kept the 2tb drive for a data and games drive. Machine is snappy and excellent now.

 

^On that note, any recommendations on an M.2 NVME SSD? I believe I've come across someone who mentioned a specific one on Ali but can't seem to find the post.

 

Thank you for the XMG Fusion one. Had not seen it. Only mainstream pub with US exposure in your list. I know Dave and saw his; but his video is really not a full review. I get cautious when all the videos I see about something are from the same people, who I have never heard of before.

I appreciate the magnitude of these laptops. Just a little surprised that no major tech mags have covered them.

 

Yeah it doesn't seem to be working for me properly either.

 

Thanks!

I am using a Samsung 970 Evo Plus, and am happy with it

 

Same here (2070 max-q), I guess they "fixed it" in BIOS update

 

Looks like it's time to liquid cool! Lmfao I can't believe Intel would leave this limited to 75C. This machine has so much potential and still beats even the newest 2070 Max q laptops that just came out. If only the increased the thermal limit to at LEAST 82C id see huge gains in performance

I've noticed stuttering when I'm in the more frenzied phases of games (i.e. precisely when you do NOT want the game to start stuttering) as well, which since the fans are going at full blast etc., I'm pointing the finger at thermal throttling ... if this machine doesn't perform in games, it kind of defeats the purpose of getting it in the first place! We need some kind of petition...

 

Someone start a change.org petition

Still on BIOS 52 here and it´s working fine. So they "fixed it" somwehere between 54 and 58...

 

Don't you have your own bios that works?

Sent from my Moto Z (2) using Tapatalk

 

I do, but that won´t help anyone here to figure out where Intel added the new software overrride (e.g. Asus) block code...

 

Is it possible to downgrade bios? Or we locked out of downgrading? Will your bios ever come out of beta or it won't ever be available? Thanks for all the help perma

Sent from my Moto Z (2) using Tapatalk

 

Yes you can just downgrade. Intel made it pretty clear that they don´t want my Mod to be released...sorry.

 

What a bummer, part of the reason I bought this laptop was the hope of your bios someday being released. Now I will never know 3000 MHz ram or 87C thermal limit of gpu :/ downgrading is an option but then I have the battery drain bugs....

Sent from my Moto Z (2) using Tapatalk

 

I don´t think v52 has the battery bug...you can also use XMP via XTU...

 

So default bios on v52 works with xmp....I gotta try that

What mod are you running?

Samsung 970 EVO (plus) is good, but still quite expensive. Best bang for buck would be something like Kingston A2000

 

Anyone have the bios 52 version for download? I don't think eluktronics has it up and I don't remember the exact url

The best performance and it's locked out to everyone else :/ I'm a salty dog, I just want to feel like emperor palpatine with UNLIMITED POWER

So you modded it into a toaster That's neat. Jokes aside, is there any use to it, if you are hitting 90 and 88C on cpu and gpu.

 

Bro I'd be happy if I can get perma's mod and then 3D print a bottom panel to allow for liquid cooled cold plate while docked to my 165 hz QHD display at home and then just keep the performance @ 80% while not docked and on the go. We need to make an online petition for Intel to raise the thermal limit. Even if it's 82C I'd be happy because I saw my GPU cap out at around 80C with a power limited CPU. Maybe a modified heatsink where the pipes between the GPU and CPU are separate because let's be honest, we know it's the CPU temps that are throttling the GPU most of the time.

Anyone have the password for the zipfile? Why do they lock it like that?

 

Samsung is overpriced for what you actually get, I switched to ADATA XPG drives, they use the exact same nand and controller as the bigger brands other than Samsung and are fast and reliable.

 

did you try eluktronics?

 

I tried it and it didn't work. (Neither did "intel" or "mag-15" or "mag15" or "qc7", lol)

 

It's not asking me for a password...
