GL502VS Discharging while Plugged-in

[ido505]

Hi,

I have got the new GL502VS with the 1070 gtx in it.
After reading a few topics in other forums I saw that some people complains about the battery - saying that it keeps discharging while connected to the charger.
Then, I noticed that it happens for me too.
It's not a big deal, but around 8% in an hour of playing Mafia 3.

Do you guys aware to this problem?
Is there anyway to fix it?

Thanks.

Last night after playing for 2 hours GRFS in coop guerilla mode, don't know if this mode is more demanding due to plenty action going on all the time, and I've seen a discharge to exactly 75%.
So this morning played again, and later on did the CPU under volt thing and got some very interesting results regarding temperature playing GRFS. However it does not seems it solved the discharge issue.

I will post an image of those results later on once I thoroughly analyze it, but in short what I got was that CPU temp never ever got above 42C. It's kinda flat.
I still haven't played out with the GPU

can you tell me about this under voltage thing? It's a 46 page thread so I dont have time and Im at a conference tried to demo my game right now while my laptop is barely staying alive.

I've used Intel Xtreme utility software to reduce the voltage as per instructions what I have found here on this thread.
I reduced it by 150mV and it was OK, after 4 hours of the same game tonight (game has amazing graphics details at some moments), I am seeing discharge at 94%, at the same game settings (all maxed out with 1080). Last night it was 75% after 1.5 hrs

I also did have underclocked the GPU a bit. Obviously I was supposed to undervolt it, but even once I enable it in settings it remains greyed out and I cannot slide the voltage on the GPU (MSI Afterburner). I am not convinced this undeclocking helped for the temperature but will stress computer more tomorrow with DE:MD or ROTR to see what'll happen. will post what are the results.
Anyhow tonight the temperatures were CPU - 77 to 80 C max and GPU about 70C.
I found that OK. I also keep cooling pad, just to have more natural flow of the air it helps a bit.

and finally, this morning trend that I've seen was not updated or something by IXU and it showed 42 C with the same game, but now that's not the case and temp is almost double than that.

For me this was the best buy laptop (light and actually portable for relatively good price with hardware it offered) because i'm traveling a lot, so I do not wanna return it and its way too personalized now (dual boot, plenty games, etc), rather would like to make it work properly alone with this community help of course, though it all works as of now.
EDIT: I am aware product is faulty, and we should get something official from Asus, however seeing all the pages here, there will be no support, so we're on our own here But it is definitely last product I've bought from Asus.

Daggasoft,

I don't know if this will reach you in time, but this is how you undervolt the NVIDIA 1070 GPU. For me this was the single biggest power sucking component.

You basically need to install MSI Afterburner and edit a file to allow the software to modify the GPU voltages.

Reducing the voltage of the GPU is not guaranteed to be stable, but I've tried this on three GL502VS machines and all of them operated fine with the NVIDIA 1070 capped voltage/clockspeed of 825mV at 1700MHz. But this may not be true on all machines.

Good luck!

Many, many thanks for this, I was really unable to figure this GPU voltage out.

I think the best thing we can do is take it oublic. We should publicly shame them on Twitter and get a petition going

[ColinMacLaren]

For me it's like:

- no voltage reduction ~ 15% per hour
- only CPU voltage reduction ~ 10% per hour
- both CPU and GPU voltage reduction ~5% per hour
- both CPU and GPU voltage reduction and limiting fps - zero battery drain

Asus agreed to replace my unit. Hoping this works out.

Well I was facing exactly same problem with my ASUS G751 and majority users I know.

It's basically a problem between ASUS USB Charger + (Software) and ACPI drivers (Battery calibrator).

When these 2 software/drivers work together they ruin ASUS ROG.

I uninstalled USB Charger + and changed the ACPI drivers to another ASUS model.
I apologize I don't remember of which model was the drivers because I had like 6-7 downloaded on my PC and I tried each one of them like a year ago.

I will never recommend you any solution like this, but I think ASUS must fix this problem by working on ASUS battery calibrator with ACPI drivers.

If you need a temporary fix then:

Go to Control Panel>>Power Options>>Choose: Balance OR High Performance>>Change plan settings>>Change advance power settings>>Battery >>
Set these as following:

Critical battery action= Hibernate (both on battery and Plugged in)
Low battery level = 5% (Both)
Critical Battery level = 1 or 5% (Both)
Low battery Action = Do nothing (Both)
Reserve battery level = 1% (Both)

Just try to empty/drain your battery as much as you can once a month and charge it from the 0% - 1% level.
(Make sure your Nvidia Experience is optimized for Plugged and use same points in Battery section).

Atleast this will make your battery in good shape until ASUS decided to fix the ACPI drivers! or introduce their own Battery Calibrator.

God Speed!

I'll follow with the personal observations on topic this.
I have reduced the GPU voltage curve following above instructions, while CPU was already under-volted earlier and then I played latest deus ex on maxed out settings. I did not notice any difference whether I have undevolted CPU and GPU together or only CPU, so I brought GPU back to default.
Downing on the CPU itself solved problem by a huge. Tonight after playing 4 hours latest Deus ex on ultra settings, it dropped to 95% first half hour or so, and after that it never went down more than that.
So I am gonna stick with downed CPU only...
I am on 180 Watt charger, and with 6th gen processor.
Temperatures were between 77-80 for CPU and 72-74 for GPU.

Being extremely subjective now, I am happy with this and hopefully this will remain like this, I am not planning on playing VR games anyways anytime soon.

Thanks to everybody who figured this out and those who keep sharing it with community.

SO No official answer or Fix from ASUS yet,

I tried to contact them, via their support site, requesting my money back because it is a defective product, that doesn't fulfill what they promised, and they answered to me after 10 days .. considering that this is my third attempt to try to find a suitable solution, and that is their average respond time, it means that I hjave at least 50 days of wasting time and consuming my warranty....

They said that they cannot return the money, that I have to talk with the vendor which is Amazon, and When I try to talk to Amazon they are telling me to talk with ASUS.. SO I'm in a loop hole that nobody can solve...

Worst Customer support that I have experienced, really in shock about this.

Could somebody give any recommendation?
