1.the model that comes with pentium dual core will equip intel hd graphics, and same goes along with those models that come with GT740M which has nvidia optimus equipped.

2.its GT740M for the Z400. the GT740M is on par with GT650M.

3.the acer aspire v3 with full hd IPS display.

4.not really. the laptop is yet still new. some more, there isnt a festive season. BUT, PC fair is this week at KLCC! take a look at PC fair is better.

5.check whether its AP set or local lenovo set. the product codes normally end with (MY) at the end (excluding brackets).

6.if you switch to international warranty, you have to know which country is under the international warranty T&C.

7.not sure about office softwares. i just only use MS office so far.

8.Not sure but anti-virus is pretty bothering. i never install an anti-virus in my laptop and let it 'naked' whole year. but so far, i dont get virus attacks. just dont visit prawn site and you are safe.

9.Z400 battery life up to 5 hours is applicable to pentium dual core only. if you buy i7 and GT740M, it will last about the same as Y400.

10. depends on user's thought. its just a marketing gimmick somehow.

if you are into gaming, entertainment and assignment, you should get the core i5 spec (w/o touchscreen). its cheaper compared to i7 spec.

1) There are a lot of configurations for the same model. Z400 is more like a design, which makes up a lot of sub models.
2) GT 740M = GT 650M. GT 730M is slower.
3) 2.8K allows you to get Z400 touch - i7 + GT 740M.
4) PC Fair? Ignore it. A lot of con cases happened.
5) After getting your laptop, register your serial on Lenovo's website .
6) That's personal preference. If you don't mind pay extra, why not? It is good to have extended warranty.
7) Kingsoft Office Suite is an alternative to Microsoft Office.
8) Normally 3-6 months trial version is included. But it does not matter. You can install yourself. There are plenty of free 1, in fact you can even Microsoft Security Essential. Free from microsoft as long as you have the genuine Windows! There is no single paid version anti virus provides 100% protection, the main issue is from user.
9) That is more like full charge battery life. Yes, battery is a wear and tear hardware. But normally, the batter life will be shorter in real life rather than the one stated on the website due to different usage level.
10) It is good for Metro UI, kinda practical.

2. the GT740M is a newer generation of nvidia graphics, while the GT650M is an older generation.

4. this week as in 7/4/2013, from 12-14 April.

8. not sure. watched unboxing videos from youtube but they dont come with.

9. yes, because the Z400 is equipped with 4-cell battery. however, battery life varies on task.

10. get the i5 better. since you are not into professional work and dont need the power of quad core. it costs only RM2100-RM2300.

some additions to warranty. what i stated in 1st post is 1st step to know your set (to prevent you being conned). like sifu kingkingyyk said, after getting your laptop, you can register the product code at lenovo site.

If you intend to go pc-fair just bring along your tablet or your smartphone, surf to http://support.lenovo.com/en_MY/product-se...us/default.page  , key-in the serial number and it will show u the location, warranty expiration date, model of the unit you intend to buy.. That should give you some peace of mind.    Don't wait till you have purchased the unit then to realise you can't find the serial in that website..is too late obviously.

something like heavy coding compilation, heavy AutoCAD, Autodesk and so on. processor does less than the graphics card do in gaming.

Kingsoft is a 3rd party software.   and it runs like MS office, but maybe different user interface.

Metro UI is the user interface that replaces the start menu in windows 8.

if you buy the i5 version with rest of the money, extend the warranty to 3 years.

i5 is a decent choice for non-intensive workloads. Gaming should be no problem.
3) SSD.
5) Backed home, check out your serial and register it on Lenovo website.
7) Yes
10) The "Tiles" in Windows 8. Google it.

All sifus here, i just bought the Z400 today. i wonder how can i disassemble the battery? lol.after it fully charged, i find no way to disassemble it.

the battery disassembly needs you to take off the back cover by unscrewing the screws. the difficulty level is not yet known.

SSD is solid state drive. its a hard disk that doesnt have moving components in it, so it helps in boosting the read/write speed.

yes, they have no release clips for battery removal and the battery is located inside the laptop. this issue only apply to ultrabooks and ultrabook size laptops.

I bought my Z400 a few days back, and I had a bit of problem knowing that the battery is not user removable... But my other choice was the z480, which the shop only had one unit left or something >< (z480 was replaced by z400 and they stopped making the z480). But the keyboard is backlit and the design looks better.

Anyways, this laptop has around 4 hours or normal usage (intel HD4000) usage and around 3 hours when I played Need For Speed Most Wanted 2012 on full graphics (since the resolution is not 1080p, i guess it's not that much heavy? not sure), and the game didn't lag at all. but you need a num pad to play this game >_>

And lemme answer some of your other questions 

(2) I read that both are around the same, but one the 600 series use DDR3 and 700 series use DDR5. But I can't tell the difference about which is better. But I think DDR5 has VRAM which is waaay faster than nor computer RAM.

(4) I bought mine from the Lenovo outlet at Midvalley. 2199rm + 120rm (4gb ram). Friendly staff and did all the work for me (installing a lot of software and registering the antivirus (3 years McAfee). You can get the SSD from there as well. And it is advisable to get the extended warranty Normally is 2 years warranty. But add 99rm for an extra 1 year, for a total of 3 years. The last day to add the extra warranty is 90 days before your warranty expires. But 3 years is the limit for the warranty....

(5) From the Lenovo outlet, I'm really sure it's official warranty xD

(6) I think the warranty I talked about on (4) is international, you can ask the staff when you buy.

(7) They offer MSOffice from the official outlets. You can from there as well (I think)

(8) McAfee 3 years, I mentioned on (4) xD

(9) Important if you want to work while traveling. Around 4 hours for normal MS Office usage for my new laptop (few days old) and around 3 hours for gaming. There are Powerplan options which you can save battery or use more power~ (And there is a cool dust removal thingy button where you press it, and it increases the fan speed to max I think, I use it to cool down the laptop while playing games xD)

(10) Touch screen makes Win 8 look cooler But for normal usage, for me, non-touch screen is good. Prolly better

Nice reviews. 
Wow, 4 cells battery can last for 3 hours of gaming, its amazing. 
Use dust removal feature to improve cooling is a good idea. 
Z400 is a portable budget gamer choice. 

SSD is expensive yo. assume 120GB = RM330. and so far, 1TB SSD is not yet available yet in 2.5" form.

yes, you have to keep the battery in the laptop for the rest of your life but it is replaceable. so dont worry.

ultrabooks are having this concept too. even hybrid laptops are like that. so some manufacturers released extended battery cell to improve battery life. the lenovo ideapad z series is an ultrabook like laptop but they are heavier compared to a real ultrabook.

Use a u2 cooling pad + dust removal button to turbo boost the fan speed will maximize the laptop cooling. 

SSD is a solid state drive. you are not necessary to replace HDD with SSD as SSD is an extra only. upgrading to SSD depends on the owner's decision whether now or in the future. and yes, there will a significant difference in performance, HDD is slower compared to SSD but SSD is more expensive than HDD.

not necessary. like i said, its an extra.

if you wanted to upgrade to SSD, get Intel,  the lowest RMA rate record holder.

not consider as luxury but high performance upgrade only. (not really necessary to upgrade the HDD to SSD.)

RMA - Return Merchandise Authorization, a process which is to claim the reseller/retailer/manufacturer to replace the product which turns out to be defective after purchase.

yes, SSD has different brands. so far, there is OCZ, Plextor, Samsung, Kingston, Crucial, Sandisk and more.

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]

32gb isnt enough actually. estimated usable space = 27gb, if installed windows 8 (18GB), i dont think there is enough space for you to install other programs. 64GB at least.
i guess you are talking about the mSATA SSD in your laptop, not standalone SSD cuz Z400/Z500 only has a hard drive bay only.

anyway, so far there is no SSD that is in 1TB size yet (in 2.5" form) but in PCI form, there is 1. that SSD has a read/write speed of 1000/1000 and above which makes the fastest SSD.

around RM200 if im not wrong.   and yes, it does boost OS booting speed. take note that there is another type of SSD, that is mSATA SSD. its HDD sized but they are RAM like module that is installed in the daughter board of the motherboard.

Intel is the best SSD so far. retailers have less complain from customers so its pretty reliable. if you wanted to get it, depends on your budget. yet, its not recommended for you to get SSD.

extend warranty and get a cooling pad is better. the reason i say not recommended to get SSD is because the price is still skyrocketing. you see, a 60GB costs around RM200, while at that price you can get a 500GB HDD for more storage. save up your rest of the money and only plan to upgrade to SSD in the future once you earned more money.

your basic warranty is 2 years, so it wont be expensive extend it to 3 years. getting a notebook cooler, dont need specific brands, just to mention get those made of aluminium is enough. price varies on the size of the notebook cooler and essentials provided (like LED light, number of USB ports).

EDIT - maybe around RM200-400 for total.

not necessary to get SSD bro. even if you get it, you are in the risk of 'data economy instability' if you know what i mean.

my mean you are in risk of storage shortage.

lol, need time to mend my english.
