Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

@Alienware Area-51 ALX 2006  There was a Pentium 4-M chip actually DESIGNED for laptops, but I had an Dell Inspiron 9100 that had a desktop-grade Pentium 4 CPU installed in it.

Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

Because it’s rare to see 330watts on the m15 and m17 that’s why. They even ship the i9 / RTX 2070 super models with the 240watt.

 

Heres a 330watt PSU from Amazon:

Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

Thanks again for all the replies. 

So theoretically, if I am gaming for 5-6 hours straight (which I don't do) the Alienware would shut down because there would not be enough power?

I was hoping this new laptop would last at least as long as my Inspiron 15 has. At this rate, I don't see that happening. I had to make a decision with their 21 day return policy. I requested a Return Authorization and sent the laptop back to Dell today.

Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

Probably since its draining itself while its plugged in. Does it say plugged in and charging or just plugged in not charging.

All,

Hybrid Power Design (15 R3/15 R4/17 R4/17 R5/m15/m17) Note, this also applies to the newer m15 R2/R3, m17 R2/R3.

Does it apply to older Alienware systems like the r2 revisions of the 13,15,17?

Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

@DELL-Chris M  Thanks for linking that article.  Wasn't aware this was officially written up somewhere.  Although I take issue with the section "Benefits of the Hybrid Power Design", specifically the claim that "It protects the battery", for two reasons:

  • The behavior described there (not charging back up to 100% until the battery drops to 94%) is commonly found on other laptops, both Dell and non-Dell, and has nothing to do with Hybrid Power Design.
  • If Dell is concerned about protecting the battery, then they shouldn't implement a design that requires the battery to be actively discharged while connected to AC.  That extra discharge activity while on AC power and under load (and the need to charge it back up afterward) is what's going to affect battery longevity.

And the other claimed benefit that "It prevents system throttling" could also be achieved by simply shipping systems with adequately sized power adapters.

Ironically the only benefit of Hybrid Power Design that could LEGITIMATELY be claimed -- "It allows systems to be shipped with smaller, lighter, and cheaper power adapters" -- went completely unmentioned in that section.  And of course whether users would prefer to reduce bulk and weight or have a system that can operate without drawing from the battery and ultimately throttling is an entirely separate question.

Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

@tscan2004  If how the XPS 17 operates is any indication, the system won't drain the battery to dead if you have a sustained load.  Instead, when the battery drops to a certain level, the system throttles its performance enough to allow it to run "sustainably", i.e. without needing to continue drawing power from the battery.  But that of course just means poor performance.  And at that point it might not be charging the battery either, so in order to get BACK to full performance, you'd have to reduce the load long enough to allow the battery to charge again.

Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

The gaming I’m doing isn’t even that demanding. It’s Football Manager for crying out loud! The M15 gets as hot as a super nova in no time at all.
 I thought I was buying a high performance laptop.

Re: Why does my M15 R2 Battery Drain while gaming if it's ALWAYS Plugged?

Any game can drag a computers performance down to a level if the game is set to a Very high preset or ultra settings.

I was playing NFS Rivals on my area51m with the RTX 2080 / i9 version on Ultra Settings @1080p 60FPS with Render settings 4K down to 1080p. My GPU and cpu heatsinks reached 200F and my laptop was getting hotter and hotter.

i did that on my 15 R1 and the battery started discharging even though it was plugged in. I had the 240watt instead of the 180watt that usually comes with it. I had to then connect the 330watt to prevent discharging but it shows how if your system comes with 1 power supply and it’s being used to it’s limit it’s going to draw more power than the adapter can provide.

 

FYI it was the 980M and the 4710HQ model which only is supposed to draw 180watts.
