GL502VS Discharging while Plugged-in

ido505
Level 8
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.

Here is something you can do:

Download MSI Afterburner or EVGA Precision OC. You want the RTSS server that comes with it. Next you want to download HWInfo that can be used with the RTSS. It should have instructions on how to get the On Screen Display to include the selected HWInfo you want. If you select the battery/power info, you will be able to display the power when it is in idle as well as when you are gaming On screen. You will notice the fact that the charge rate drops during gaming which is what is allowing the battery drain past the thresholds.

EDIT: During Idle, you will have to look at the HWInfo application. During gaming, it should default to the upper left corner.

Hey, just joining in, I have the same issue even when not playing a game but using multi monitors (1 HDMI, 1 USB, 1 Wireless project to Roku) nothing really stressful Webex on the HDMI, PDF on the USB, simple workspace on the builtin display, and some IP Camera to monitor my dogs downstairs on the roku. The fans don't even kick on when I do this where The Witcher 3 will... I joined the class action suite.

Thank you for contacting ASUS Technical support, my name is Adrian C. I hope you are having a wonderful day today.

I am very sorry that you are having this issue with the device battery draining . I understand how frustrating that can be, but I can definitely help in resolving this issue for you.
This is a normal condition for battery protection, and there is no problem in either battery itself or charging function.

When battery is charged up to 100%, the notebook will automatically stop charging. At this time, battery will self-discharge very slowly owing to the chemical characteristics of Li-on battery even though the notebook doesn’t consume any battery power.
The current design of ASUS Notebook comes with built-in RSOC (Reconfigurable SOC) and the purpose is to prolong the lifespan of the overall battery. Below description explain this phenomenon:

When the battery capacity is below 95% with AC adapter connected, the battery would be charged to 100% then stop charging.
When the battery capacity drops from 100% down to 99%~95% with AC adapter connected, the battery would not charge until power level drops below 95%.
When the battery capacity remained around 94% to 97%, battery would not charge with AC adapter connected. You can unplug and re-connect the adapter for several times to resume charging to 100.
We value your business, thank you for being a part of the ASUS family.
If you have any further questions, comments, or concerns please do not hesitate to let us know, we will be more than happy to assist you.

The problems reported here are for the battery going past 90%. The laptop has been apparently designed to drop down to 90% but should start charging again at 90%, even give them 89% to be generous, back to 100%. There are those of us who experience this, but instead of charging back to 100%, it just keeps draining. BIOS updates help, but do not resolve the issue. The original BIOS I had was terrible, but going to 303 helped slow the draining, but the issue is still prevalent and provable. Using MSI Afterburner, actually the RTSS that comes with it, and HWInfo, you can see what the charge rate is and when gaming, it cuts the charge rate drastically.

I am one of those people, that was just Asus's canned response to me not fully reading my support notes. I will drop into the 80's

Same, if it makes you feel better, I sent mine in for RMA for the drain and noted that the power brick went bad. They just replaced the brick and called it a day even though the RMA stated both issues.

Yeah, it just sucks. I have two power bricks, one for travel and one at the desk and it does it on both. However I never tested to see if it does this while connected to a 220v outlet... I know it will just step it down but meh. As said above a few posts if its really just when the system is under load is draws 183 but the brick is only 180 then why doesn't Asus just upgrade the bricks and be done with this mess.

If you have the Kaby Lake 7700HQ, you should have a 230 or 240 brick. Can't remember but it should be one of the two. If you have a GL502VS with the 6th Gen Intel, the brick is too small. I am not rep for ASUS, but you may want to ask them about getting you a new brick.

My philosophy with laptops and especially gaming laptops is that they are marketed for a certain customer at certain specs. It should run at the exepcted spec without the need for overclocking or underclocking. Same goes for voltage. When the laptop cannot do that, there is an issue. My PC has a slight OC and liquid cooling, but that is fine because it can be modded to handle these things. Laptops are different creatures, and most do not have the capability to freely mod and go crazy.

Hi,

Unfortunately, a larger adapter doesn't help with the GL502VS with the 6th gen. cpu (like i7-6700HQ) which others have reported trying.
It may be too late if you are no longer under warranty, but there should be other options which HQ has helped arrange as mentioned in the post below that you can pursue if you have the GL502VS with 6th gen. cpu, so you may want to continue looking it if under warranty and let us know if there are any problems.

We also have the GL502VS with 7th gen. cpu which internally we call the GL502VSK using a different motherboard as well as 230W adapter which HQ has not officially confirmed has the battery draining issue below 90%, so for any GL502VSK customers who are seeing this problem, it's up to the local offices to resolve this for customers.
Thanks.

I got mine on 09/09/2016 and about 5 months in my USB ports failed and they replaced my MB but I do believe I am a 6th gen.
