So here's the issue:
Several months ago, my AC adapter light would shut off during gaming. Upon some google searching, I found that some people said I should ask for the 240W adapter instead of the 180W adapter that came with my laptop because I have the GTX 980m GPU. After some arguing, I got it.
A month or two passes with no problems.
Now, every 2 weeks or so, randomly even while watching youtube, my laptop stops charging. but the light on the AC adapter is still on. If I re-plug in the AC adapter, it only charges for a few seconds, then stops. Only fix I've found is to remove the back cover, remove the battery connector, hold power button for 30 sec. (power cycle). This fixes it for about another 2 weeks until it happens again. I should also note it doesn't seem to entirely "fix" it since although it says "plugged in, charging" it says ________(blank) until fully charged, and the battery icon is not doing the charging animation like it should be. (It does do the animation for about 15 seconds if I replug in the AC adapter then stops 3/4 of the way but still charges)
I have the latest BIOS, btw.
So the agent I talked to asked a bunch of questions but all he actually told me to do was while in the BIOS, to press the Function (Fn) key + X. He said that "resets" something to do with the software or drivers of the battery. Since my battery was 100% and I had just done the power cycle, it was currently working so he said it was fixed.
When I asked if it happens again what I should do, he said to format my PC. I've done that already.
Has anyone ever heard of this Fn + X key combo within the BIOS? It sounded like BS to me, I don't even think the Function key is enabled while inside BIOS? There was no message or prompt when pressing it and he said that was normal. WTF? When it happens again im gonna call back and make sure I get a different rep.
I've also tried reverting back to A00 BIOS but it didn't do anything.
Anyone got any ideas?
Thanks in advance.

Did you enable desktop mode charge? You can find it by right clicking battery icon in notification tray and just hit Desktop Mode Charge. After that, check if its enabled or not? If its enabled, click on a button saying " Charge battery to 100% one time" and issue will be fixed.

Yes, I have tried both having desktop mode enabled and disabled. Currently, it is enabled. It does not fix the problem.

alienware overcharge the cells to 4.4V to achieve the 92whr on that model ( like mine) so these batteries tend to die soon ... in this moment i am without battery

Check the DC-in cable on the inside of the laptop, its next to the battery cable. Make sure its not burned. There are some faulty cables around.
If thats not the case. check hwo you can clear the NVram on your model. ON the R3 you have to short a jumper underneath the ram modules. But I dont know if thats the same with the previous model. I had a similar issue once and it was fixed after I did that. My PSU would "disconnect" every minute, while the PSU itself wasnt faulty, the cable wasnt etc. It was pure a software thing.
Also running 18months now on the same battery with only 1.8% wear since day 1. -

@rinneh 4,35v that cells need 4,35 to achieve the 3400mha ( in fact they are designed to achieve 3200mha) but Dell force the cell
http://www.candlepowerforums.com/vb/showthread.php?389491-Test-Review-of-LG-18650-E1-3200mAh-(Green)
"These batteries can be interesting to drive led lights due to their slightly higher voltage, but it looks like LG has traded high current ability for capacity compared to the older 3000mAh cell.
When looking at Wh, this cell can match a 3400mAh cell, due to the higher voltage.
I will call it a very good battery, but a 4.35V charger is needed to really use it."
i hope you understand now how cells works on batteriesPapusan likes this. -

@rinneh i dont know if you dont catch it... you can find cells out there that can match 3200 at 3.8v-4v out there. this specific LG cells need 4,35V to achieve 3400mah
look at the capacity ( the blue line) the cell need high voltage to achieve high capacity ( is easy to understand )Papusan likes this. -

@judal57: When I was charging the laptop battery, it was running too hot so did the palmrest too. The battery magically healed itself the wear level was 10% after charging wear level reduced to 9%. I don't know how, do you have any idea?

@rinneh 300 cicles are bad to me. specially for lithium batteries. the less i could accept is 500 cicles. i can live with less capacity and more lifespan
the quality have to bee good, but when you take a 3200mha battery and force it to achieve 3400mha you are not going to have that 300 cicles
you only have to have 1 faulty cell to become the entire pack unusable. in my case 1 pair of cells. the another 6 are good -
Anyway they arent pushing the battery beyond specifications. Both the R1 and R2 had solid batteries for me. It always can go wrong ofcourse. But this can even happen by unplugging the battery cable and have bad luck that causes a small short. -
i can live with 80% charge for more lifespan ... they should user decide that
i have had 3 batteries, all are dead now. i dont want to spend on a battery pack anymore, unless i can be sure that the pack contain panasonic cells -
