840M DDR3 starts to stutter if you want to play recent games at anything above 768p med-high settings. It'll play a slideshow if you want to play them at 1080p ultra settings. Skyrim is a 2011 game, even R5 M230 in the sub 30k laptops can play it at the 720p low-med settings.
Gaming on battery is never recommended at it shortens the battery life and games on nVidia GPU's will lag on battery because of
Optimus which was designed specifically to reduce power consumption. Its not an issue.
My dad has a Dell n5110 and I regret that we purchased it. I was a noob back then

[MENTION=184724]kkn13[/MENTION], you remember the overheating issue I posted about the same laptop. As it happens, the screws are unmovable.

I've tried using screwdriver from 3 different sets. Doesn't helps at all. The vents are placed at the bottom which forces a non-techie user to buy a useless cooling pad.
bro I know what you are feeling,but what i meant about the battery thing is that it doesnt run stuff properly on battery, AMD Enduro was very poor in the past but with the latest AMD official and Leshcat drivers,none of the Enduro or Optimus problems occur
It is certainly an issue if the laptop struggles with Youtube 1080P videos on battery given that a laptop is meant to be portable
realistically speaking even I know laptop battery life is always poor,regardless of laptop and will rarely cross 3-4 hours but what if I need to show my parents something or if i have to use it at work or college where everyone literally dominates over the limited power sockets
skyrim may be a 2011 game but its a benchmark of sorts to evaluate a laptops performance
its engine etc is still very very advanced and heavy
as for 840M DDR3,R5 M230 ,I cannot comment much on them because Ive not seen/used/owned a laptop with those gpus
all i know is what ive seen in my laptops or my friends' laptops
and i know for sure, the Nvidia vs AMD arguement is kinda invalid
its quite natural to end up with a poor product and feel the other brands are better but thats not always true
Both AMD and Nvidia are good at what they do and in each price range/category one is better than the other but you cant say Nvidia is better than AMD or vice versa
also going by 2 poor DDR3 cards doesnt mean all DDR3 gpus have the same issues
thats like saying all marutis are small and underpowered by using a Maruti 800
about your N5010 issue,I suggest trying to get those screwdrivers loosened out locally once and for all and also insist on being there to witness him removing it etc
after that you may get it screwed back on looser than before so as to open it easily , yourself in the future
Dell is a good brand , dont worry
If you feel it really overheats alot,change heatsink etc,it only costs 750 bucks in reputed local service centres(not official,other companies)
another option is blowing air using a can of air into the vents
this wont solve the problem in the long run imho as the dust etc may fly onto your other components
hope you havent taken offense to my comments

im just stating my views as I have laptops with AMD and Nvidia both.....
