Which one should I buy, Lenovo S400t IFI or Lenovo Y400N?

It's not bad for money, Y400 gaming laptop, and the performance is two streets away from S400.

If you've made up your mind to get this computer, it's just a matter of where to buy it.

Nowadays, the digital plaza is full of chaos, and all kinds of businesses are mixed, so you must be careful not to be deceived by unscrupulous merchants when buying a computer.

First, pay attention to the outer packaging of your new computer to see if there are any signs of it being opened.

Second, be sure to buy in a store with a formal invoice, which is now generally a 17% VAT invoice printed by a regular computer. There are invoices to enjoy the national three guarantees, in order to enjoy the regular manufacturer after-sales service from the date of purchase, some people may tell you how much discount you do not bring a ticket, the same warranty, and so on. I just want to tell you, you must be invoiced, thousands of dollars of computer money are out, is there still a little bit of invoice money, there is an invoice to enjoy the national three guarantees from the date of purchase, is the basis for enjoying the protection of national laws, no invoice when there is a dispute, very troublesome.

Third, don't be sold to change the order, the so-called change is to recommend you to buy another "better" computer, because you rushed to this computer past, the configuration of this computer, ** you already know very well, it may be difficult for merchants to earn high profits, so they find a way to recommend you to buy another so-called "better" computer. (Note: Of course, it is not excluded that some enthusiastic salesmen do want to recommend you better products, but if you are knowledgeable, if you can distinguish the authenticity with a clear eye, you can listen to his recommendations).

It is recommended that you shop online: JD.com**, Tmall, Yixun, Newegg.

Reason: convenient, time-saving and trouble-saving, regular invoices, national three guarantees, no need to bargain, so as not to be deceived by bad merchants.

If you want to see what other computers you can recommend, I can also recommend a few other computers for your reference. The Lenovo one you choose is still good, and the third-generation core platform can meet daily entertainment and work use. And Lenovo's reputation has been good over the years, and word of mouth is in a sense proportional to its quality and after-sales service.

To buy a notebook, you must first look at the brand, if you don't have to buy Lenovo, it is recommended to change the brand, this brand is very expensive, not cost-effective, it is recommended to consider Dell Acer, if it is cheap, you can consider Shenzhou. Buying a notebook mainly depends on the graphics card, cup, the size of the memory, whether it is a solid state drive, if it is a mechanical hard disk, look at the speed, if you also pay attention to the appearance, consider the size and color. If you buy online, it is recommended to compare a few **different**, compare Jingdong,**(It is recommended to look at the evaluation and store reputation)** and gifts.

What does the landlord do with his notebook? Gaming or office or watching movies?

When you buy a computer, you can bring Master Lu with you and test it when you go.
