how to c is a local set?

gaming is considered heavy graphic usage. so its not necessary for you to use i7 as the i5 is enough for you to game. however, not sure about kingsoft thou cuz MS office is still widely used.

3D rendering = heavy usage
so need i7, am I right?

my current laptop i3 do 3D rendering suck like shit.. rendering a still image already took me hours LOL

Yeah, you prolly have to keep the battery inside for the rest of your life. /:
And yeah ultrabooks have the non user removable batteries, cause errrr... not sure, using smaller batteries to make em light i guess? hahah

Yes, there's the nvidia optimus option. You can either set to use intel hd4000 or the nvidia dedicated graphics card. Or set it to choose by it self so that you don't have to change it al the time
When the laptop needs heavy graphics power, it automatically uses the graphics card, or else it keeps using the intel graphics. And you can also set up programs to which ever graphics you want. for example, set up some games to use the nvidia graphics and it'll automatically use that whenever you use that program~

(2) Yup, not much of a huge difference.

(4) I bought an extra 4Gb ram only, which was for 120. The 32Gb SSD was over 300 so I didn't buy it /: My Budget was flat 2K but I went a bit over it and now I'm suffering with my daily life a bit xD

(9) Power plan option only changes the processor speed i think, so when the laptop needs less speed, it underclocks the processr. Or when it needs a lot of juice to play games, it kicks it up and uses the turbo boost. I'm not sure about 5 hours but it is possible if you keep the bightness at the lowest and only use less demanding programs like MsOffice

Check my previous post, it'll have a screenshot on where to find the dust removal button   think it just removes the dust from where the wind from the fan can reach. Not really the whole laptop.

I'm not sure about cooling pads, but I almost went for logitech n100 once because it has a good design~
I previously owned a netbook so I didn't really need one, but now I keep the heating of this lappy to a minimum because I don't want to damage the battery~ I play games in my really cold room xD

And here's a screenshot of the nvidia optimus settings. Auto change, set to nvidia graphics, set to intel hd. These are the three options. And in the program settings tab, you can set which program to use which graphics so that when you're using intel hd graphics and suddenly want to play games, it'll use the nvidia for the game [attachmentid=3382181]

oh okay....
anyway i feel that at least will get a bit of benefit from the i7 ba.. XD

are you an IT student?
you're good in computer hardware n tech stuffs :3

no. i have research on hardware and specs of laptops, so i know about it.
however, it is intermediate level, not expert level.

guys, wtb y400 dos...the problem right now

1)dos, how to check laptop faulty or not without os?
2)where can i find lenovo bloatware? (some of them good, some not like power management etc)

can y400 user list me the bloatware? thx

1. power on, if working just accept 1st and register product. The rest u have to rely on warranty. see your luck.
2. Lenovo official website under support duh...'

i am not a lenovo user... its just my 5cents

3D rendering relies on your graphics card.

3D rendering relies solely on graphics card?
Or do processor affects the rendering speed too? 

processor is better for hard coders. graphics card is better for 3d rendering and graphical stuffs.

so as an art student, it is better for you to go with better graphics card.

hey I;m a coder too ok.
a noob coder.. LOL

btw,
2gb grahic card should be good enough already right?

VRAM does nothing with performance. so as long you are GT720M and above, you are good to go.

hi all..
i just bought y400..
my power cod is like this?
im sooooo outdated...
