M11x FN+F2 slow down

Hi my M11x really slows down when it is in plugged in, not charging mode. Does anyone know why? and if there is a way for me to fix it

 

This will happen if your power adapter is too weak. You may be using the wrong adapter, or it may not be outputting correctly. What is the output rated at in watts?

 

its the 65watt adapter that came with the machine.
btw when i am on battery mode, the computer is fast
When i am charging the battery it is fast
but when plugged in and not charging it is superslow

 

Make sure you're on high performance and make sure the high performance profile is set correctly for battery (active cooling, 100% cpu clock, maximum gpu performance etc).

 

again when i am on battery mode, the computer is fast
When i am charging the battery it is fast
but when plugged in and not charging it is superslow.

 

Sorry I must have read that wrong.

What's that point of the Fn + F2 toggle? When I hit that on mine it just says battery enabled no matter how many times I do it.

 

Did you call Dell support?

 

Plugged in and not charging and slow?
How do you know it is slow?
Do you see high CPU usage? is harddrive constantly reading something. Seems like a performance settings issue.

Regarding the FN+F2 , I am actually really curious what it actually does?
Is there any function other than display the battery is enabled? (even that is ambiguous)

 

I customized my alien fusion so that everything is maxed in battery and plugged in. I wouldnt think it is a performance settings issue because being plugged into the wall should give me the most performance.

FN+F2 is when you dont want your batteries to be charged when plugged into the outlet because everytime you charge ur battery, it degrades over time(as in your 6.5hours unplugged will soon be 4hours and eventually be 1hour).(you press FN+F2 during bios boot, and it should work. It doesnt do anything when windows has already started)
I know its slow because the games I played have significant framerate drops. Mass Effect 2 has long load times and is super choppy.

You guys can test it out if you want, just play a game with FN+F2on (you press FN+F2 during bios boot, and it should be activated. the FN+F2 doesnt do anything when windows has already started) Play anygame, you will see a huge drop in performance. unplug your adapter/replug while gaming and everything should go back to normal as the system has gone back to charging mode.

 

Can someone please test this out, so I know its not just me.

 

i don't have a M11x but would like to say that you do not need to disable your battery. these newer battery do not degrade like that, once fully charged your system will stop charging it and will pull power directly from the power supply. to keep your battery from degrade you must also fully discharge it once in a while. google battery care for a small app that tell you when you when to discharge your battery.

 

I agree with this, don't bother with this feature at all. With my old M1530 I constantly charged and discharged (would charge when I had to, then unplug), and nothing changed.

Which batteries need the most care out of nicad, nimh, liion, and lipoly? More importantly, just the liion and lipoly. Most laptops have liion, but the M11x might have a lipoly.

 

My system would go slow with high CPU usage if I Hibernated, overclocked or returned to stock speeds, and then resumed from Hibernation. It required a fresh boot to work properly. Perhaps the battery enable/disable works the same way?

 

I've never seen this, and I almost never actually shut down or sleep, pretty much hibernate only.

 

With an Intel X25-M 80GB SSD in mine it shuts down quicker than hibernate and only a couple of seconds slower to restart than resume from hibernation Because of this I shut down now (but usually hibernate on other machines I've had).

 

You'll notice that the reported speed does not change (WIN+PAUSE/BREAK). It was the same with the Win2K problems. It may have been a background process that went away after restarting but there were a few normal processes that wouldn't settle down until I restarted (AlienFX, SlienSense, etc). I hadn't disabled search indexing at the time so it may have been exacerbating the problem. At this very moment I am seeing 15-20% usage constant across both cores with nothing in the process list corresponding to it, so I think the search service or ReadyBoost is busy doing something, but my problem before was affecting even video playback (FMV intros to games would skip).

If you haven't noticed the higher CPU usage it's probably because you removed the offending/affected applications that launch with the system by default and haven't noticed any others.-Edit-

It seems to be AlienSense. Of course, other processes including those from games and applications that were not running before Hibernation may do the same thing, if it's anything like running ZSNES on that old Win2K machine. I'm just going to disable it because it hasn't recognized my face since day 2, but I will still avoid doing it without a full restart.

Though I think it's because my glasses are always reflecting a different environment, AlienSense not detecting me may actually imply that something is wrong with the program on my system, so I'd like it if someone else with AlienSense still enabled could follow this procedure and report back:
Enter the BIOS settings/CMOS Setup and set Overclocking to "Disabled."
Boot fresh.
Watch the CPU Usage History graph in the Task Manager Performance tab until it settles somewhat.
Hibernate.
Enter the BIOS Settings and set Overclocking to "Enabled."
Resume from Hibernate.
Check the CPU Usage History graph again and see if it settles somewhat higher than before or not.
Report back.

Technically, it SHOULD settle lower if it's doing the same workload on a CPU that is now running faster, but mine goes up. I suspect that any would.

Hibernate still has the advantage of letting you leave some things open to finish later.

 

True, but in my case I'm either finished so close things down or I put into sleep (Hybrid) if I'm coming back to it within a couple of hours.

 

And I guess you can still hibernate the long way if you absolutely needed to.

 

Well Hybrid sleep is like hibernate anyway as it still images RAM to the hard drive but recovers from RAM (quick) unless battery life goes then it recovers from the hard drive like Hibernate.
