Brands normally sell consumer line laptop a max warranty of 3 years, and even if they allow you to extend longer to 4/5th year, the warranty will be rather expensive. I think 3 years warranty is about right.

The demanding software you will probably use are CAD and simulation software.

The Envy 15 has a more powerful CPU (quad core) vs the Inspiron 15 7000 (duo core), but the 15 7000 will give you longer battery runtime.
Both have a good GPU for your usage. And come with FHD screen that give you more work space.
In term of build quality, my vote go to Inspiron 15 7000.
You can get International warranty from either brand. For HP, just ask re-seller to assist you to get the correct care pack. For Dell, extend the warranty to 3 years, and if you move overseas to further study, you just need to do a Tag Transfer online to transfer the warranty to the country that you are going.

Prices are RSP, negotiable.

Get the Linux spec. You can get cheap legal OS from college. Just need to download Win OS driver from Dell website. Extend warranty to as long as you can afford (3 year Pro Support NBD is going at RM259).

"lite games" as in FB games?
Then you really don't need discrete GPU, and also don't need i5 CPU.

Anyway, if you insist:

ULT CPU has lower TDP, but can still turbo up if call for. i5 ULT is over-powered for daily office task
The slowness that you will feel is due to HDD. HDD is the biggest bottleneck of laptop performance. The way to alleviate is to go with SSD. Get SSD, 128G ~ RM300, 256G ~ RM600, replace the HDD (keep as external storage), and you will feel the laptop get a lot more responsive.

Put it this way, even if you buy a laptop spec with the fastest i7 quad core but with HDD, compare that with a MacBook Air with SSD, the MBA will feel a lot "faster" for daily office task.

Wonder why would you want to go with that S550 which is spec with the older Ivy Bridge (3rd gen) CPU Also don't see why you need touch screen on a 15" traditional form factor.

That S550 is spec with 24GB mSATA SSD, which is factory set for caching. It will improve responsiveness somewhat compared to a sole HDD setup by caching the frequently access files onto the SSD, but does not come close to a full SSD setup.

In term of quality of the display panel, it is best for you to look at the real thing itself (may sure it is exactly the model you want to buy, since panels used are changed from one spec / model / batch to another) to decide for yourself.

You will not get FHD from Asus with your budget

Doesn't matter which type of program you run, GDDR5 is better than DDR3 for the same GPU.
CAD / Simulation software typically can take advantage of quad core.

You want International Warranty, can also consider:

(note Asus Malaysia dodgy warranty support in KL)

The best GPU you can get with your budget is GT740M.

Dell
Inspiron 14R, i5-4200U + Nvidia GT740M@RM1849 [2.32kg], 4GB, 500GB(5400rpm), Linux, 6 cell; W8@RM2049

Shop don't provide after sale warranty service, the brand does.
You may check with some re-sellers at LYN garage sales section.

Btw, when did a 13" MBP has a discrete GPU?
Only the 15" MBP has discrete GPU.

You can start by looking at these Clevo. You can get them from Xotic PC if you are from US.
www.illegear.com

Also look for Gigabyte Ultrablade.

i3 and Intel HD is more than sufficient for your usage.

Prices are RSP, negotiable.
Use the remaining of your budget to extend warranty (Dell, to 3 years on site ~ RM300).
FreeDOS mean you need get and install OS yourself. You should be able to get cheap legal OS from your school.

Ask Prince J right here at LYN. He is from illegear.

ULT CPU can handle Adobe After Effect and Premiere amateur usage.

Do you mean you want 15" since you are thinking about Z510? (some time I'm really sick of guessing, follow the suggested format on the 1st post must be very difficult )
Choices are rather limited with your budget:

Vostro 5560, i5-3230M + Nvidia GT630M@RM2349[2.2kg], 4GB, 750GB(5400rpm), W8, ODD

You know Intel Atom CPU is good enough to surf net and checking email right?
i3 is over-powered for those menial tasks

Tough one.
I don't think you can get Y510P local set within your RM3k budget
Each has its appeals and flaws
In terms of raw power Y510P has i7 quad core GPU, but that is not going to make much difference for gaming since the cap is with the GT750M GPU for both models.
In terms of aesthetics, it is subjective. You should go out and look / type / touch / listen / click / carry the real things to decide

Suggested the Asus because you asked for Asus
S551LB-CJ120H, i5-4200U + Nvidia GT740M@RM2699[2.4kg], 4GB, 750GB, W8, 3-cell

Inspiron 15 7000, i5-4200U + Intel HD4400 + (1366x768; Touch) @RM2899[2.6kg], 6GB, 750GB(5400rpm), W8SL, backlit keyboard, 58Whr

In term of specs, the Inspiron 15R and the Inspiron 15 7000 (the more expensive spec) is slightly over the Asus.
But the Inspiron 15 7000 RM3.6k is over your budget
The cheaper Inspiron 15 7000, however, don't have discrete GPU (you may be able to live with that, depends on the level of graphic work you do )
The Inspiron 15 7000 is good looking and also has a solid build (if you ever get your hand on a display unit, try to bend it to appreciate it )

None of these has mSATA SSD factory spec for caching, so you need to upgrade after-market.

For your budget, if your aim is to maximise gaming experience (since you did not mention the game you play, I'm assuming they are GPU demanding games), you should aim for GPU perform like GT765M or above.
Some of the models you listed are EOL, some are under-powered.

MSI
