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.

Turns out my adapter will be here Saturday and not tonight. Boo.

As far as wattage is concerned, I suspect anything you can turn off/down would probably have a positive effect. I considered shutting off/taking out the platter drive that's in there, turning off bluetooth, etc. to see if that would fix it. I imagine turning down the brightness a bit might even help. I did install ThrottleStop and dropped the CPU down -125mv, but I am not 100% sure that it's helping.

Either way, this is pretty ridiculous that these are the steps we need to go through.

Hi,
So I have still got this issue..
The support team told me to talk to the local call center in my area, I will do that this week.
I guess they will try to replace my adapter but I guess that it won't change anything unless they will give me another one with an higher voltage..
Did you guys manage to solve this problem in other way?

I've got a ticket out with ASUS support now.

I told them already that I will not do an RMA. The computer itself is fine - they need to provide a sufficient PSU.

Well, I got my parts today and everything seems to connect up and work correctly. I haven't had much of a chance to do testing, but I'll do more tonight. I did run the latest 3D Mark to see if my scores were any different between the stock 180w adapter and the 210w one I picked up, but they were very similar. I didn't notice any impact on the battery at the time, but will test some more with actual games instead of benchmarks later.

Fingers crossed it works! Hopefully no BIOS tweaks are needed or anything.

If it does, that's yet more ammo that ASUS needs to step up and do the right thing by providing a suitable enough PSU...

Ugh. Well, it seems that the 210w PSU I'm using doesn't do me much better. After 20 minutes of playing the Witcher 3, and having started with a 100% battery, I was down to 96%. I just don't get it.

[CrimsonPhoenix7]

I think I read somewhere on notebookreview that a guy tried it but it wouldnt work without running a custom bios.

Shame it didn't work. Back to the drawing board - although its a bit ridiculous that WE are trying to figure out a fix instead of ASUS's product teams.

I read on a youtube channel where a guy reviewed the 502VS and said that he owns a 240PSU and it solved the problem...
Weird why the 210 didnt solve it. maybe an electrical protection that limits the current, I dont know..

Somehow I didn't think about it until now, but I have a 330W adapter from my Alienware M18x R2 that I haven't sold yet. Looks like the adapter works, so I'm going to give that one a shot. Why not, right?

[ripwind]

So, get this... Even with using my 330w adapter the battery is still draining while plugged in. I just don't understand. Maybe there is some sort of limitation on the actual power control unit in the laptop itself.
