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.

They didn't fix the problem with the new kabylake gl502vs. Me and another person in a different forum have both experience battery dropping down about 10% after an hours worth of use, even when plugged into the 230W adapter that is included with the new gl502vs.

Edit: I just contacted support and they told me to update the bios to 301. I'm going to try some tests on it tomorrow.

Could it be that MSI Afterburner adjusts the UV curve after you've applied it? I had everything on 1708MHZ, -150mV but now the higher Voltage areas are around 1721Mhz.

I played Resident Evil 7 today and it's still stable 60fps on Ultra and the cooling fans are surprisingly silent. I'd never have expected that undervolting made such a big difference. Also no battery drain apart from the usual (I always disconnect PSU when I go to sleep after shutting down the laptop, so it's 1% a day.)

Yep - same here... Don't worry about that 😛

No BIOS update for gl502vs yet. Your model I gues should be gl502vsk

As rusinc said, it's normal. I get the 1708 Mhz, when setting it to 1700. It's probably due to the accuracy of Afterburner. I mean if you cans squeeze out 1721 Mhz, even better. 😉

Hey guys. I just found out an interesting thing.
I wanna talk about BIOS 300 vs BIOS 201. The only difference betwen those 2. When your battery go down below 75 or 60% (I'm not sure exactly), laptop performance go down so the battery can start charging. Theres a huge diffference in charging behavior from 5% to 100% on 201 vs 300 under the huge load. I dig this forum and found out that the people on BIOS 201 expirience discharging (while playing Battlefield 1) up to 46%. You will not go that far on BIOS 300.
The main problem I have discovered that my computer discharge ratio after undervolting are super low. But, for example, I was browsing youtube on a battery power, then I plug in to play some very demanding game (Watch Dogs 2). I exp a lower fps compare to full charged battery. So I decide to roll back on BIOS 201 to see the difference. Much better, no issue with performance, but battery almost not charging at all while I'm playing the game.

I decide to stay on BIOS 201 + undervolte my CPU -125(on -150 Watch Dogs 2 crash the whole system once, so I decide -125 are better in my case) + undervolte GPU to 825mV and 1695MHz.

So if you preffer better performance while laptop charging up your battery - go for BIOS 201. If you dont care - then 300 suit your right. Also about our hope that ASUS gonna fix the issue in the future. I don't think that there will be any solution to our problem. As one persone mention above, the BIOS he received from support just charge the bettery all the time. Not acceptable for me at all.

So for people who interesting to revert on older BIOS via WinFlash (provided by ASUS) you gonna find that u can't roll back to an older one. So you have to follow this little guide.

Latest WinFlash utility can be download from our laptop support page (under the driver section). Version 3.2.2
For me it went smoth. Now I'm even more enjoing this laptop 😛
P.S. If you are not planning to undervolt your laptop. Better to stay on BIOS 300. If your laptop are always running from PSU - also BIOS 300 a good choice. Also I can't check now if there any impact on performance if your battery are charging from 95% to 100%, I don't want to roll back to BIOS 300 just to check that. But based on my previous exp with BIOS 300 I didn't notice it while gaming. So maybe theres almost no or very little impact.
P.S.S> I discharge my battery to 4% on BIOS 201, then do the benchmark - same score compare to full charge battery. Launch Watch Dogs 2 on 8% - no fps issue, same as on full charge.

Also I do the final stress test with 100% CPU and 100% GPU - discharge ration from 0 to 1800 milliwatts maximum. Same on BIOS 300.

That's true, new bios did not resolved the problem.
But there is still a hope. Alienware laptops back in 2015 had similar issues with 980m on board and 180 watt PSU. And those issues were fixed with bios update + new PSU shipping.
So, the hope is still there...

P.S. I've reverted to 201 just like you did. Combined with udervolting works great for me.

@all
I've noticed a strange thing. My GPU temperature never goes above 74 C. No matter if undervolted or not. I saw the results of you guys, and it looks like on your machines it caps at 86 C. Did you changed anything to achieve that?

Our service reps have already further escalated this issue and our notebook team are looking into this issue, we'll post updates here once we hear back from them. We apologize for the inconveniences caused.

In this case, should I get my money back and wait til I will be able to buy the new version with the 230W, or get a new machine but from the old version?
Right now my machine is back in my local trader waiting to be replaced.

Why do you keep it private with the question? I'm sure others might be interested also... Post here?
