After playing highly demanding games for a while my Alienware 17 R5's battery starts to drain while it's plugged in. This is with the 240W adapter that came with the laptop. It seems to drain to either 95% or 90% then doesn't drain further. I found a reddit post (https://www.reddit.com/r/Alienware/comments/8j1jj8/battery_draining_while_plugged_in_when_playing/) where people were claiming that although this is intended, it's still really bad for the battery. Is this true? They claimed getting a 330W adapter fixed their problem. Can anyone confirm this? If I should get a new adapter, how do I go about getting Dell or whoever to approve the new charger so I don't void my warranty? Do I even need to do this? This is the charger I'm looking at: https://www.adaptersdepot.com/dell-ac-adapters-c-122_72/original-330w-dell-alienware-17-r5-p31e-p31e... Thanks for the help.
I have exactly the same model alienware like you and the same issue happened to me and I changed to 330 watts
and I asked dell support they just changed to 330 watts without any knowledge it works better than 240 watts in game and charge but I have now other issue which is : Coil whine, also known as electromagnetically excited acoustic noise and vibration or audible magnetic noise, is one of the most frustrating phenomena in modern technology. As its name suggests, this high-pitched noise is caused by electromagnetic coils that act as inductors or transformers.
It makes sound loud while gaming at first I thought its HDD but I was wrong.
check here one of my story with R5 :
We've seen users who have changed their adapters to the wattage mentioned (330W) and have successfully transferred the power requirements to the adapter only. However, this is not necessary considering that the PC can supply the entire power with this feature.

Old post but for others looking at this, the link in the second comment is extremely helpful. This is a bios/software feature to stop throttling and changing to a 330W adapter does not change this from happening, the battery will drop 5% by design every hour until it reaches 20% and this feature will be disabled (throttling will then start during heavy usage).
And the 330W charger is noiseless, as opposed to some comments. Not a single sound from it.
What specifically does this mean "... changed their adapters to the wattage mentioned (330W) and have successfully transferred the power requirements to the adapter only"? Is there some windows settings to change per adapter?
