How to look at the good or bad second hand N7O? I want to buy the part 80

Second-hand mobile phone, first of all, you have to look at the appearance of the phone, and secondly, look at the **whether there is a problem in all aspects of the function, if you want to buy a good Nokia**, press * on the ** can see how long it has been.

Secondhand****.

N70 1300 yuan.

N73 1700 yuan].

Don't buy it if it's too expensive.

Laymen look at the appearance of the mobile phone, and insiders look at the motherboard of the mobile phone, LCD screen.

Of course, the appearance will basically be refurbished, so the appearance is only original and non-original.

Therefore, people who don't know how to read motherboards should not buy second-hand ones.

I'll tell you a secret to buy a second phone, first look at the new and old appearance, if it's quite new, you have to pay attention, it may be refurbished, and then see if the keyboard is good, use this mobile phone to replace your SIM card, hit a few**, see how the effect is, and then, take out the mobile phone battery, see if you have dismantled the machine (see if the warranty sticker has it, there is no dismantling), persuade you, the dismantled mobile phone is good-looking, no matter how cheap you don't buy, tell you, that's the case, at most two months, it will definitely be bad.

In a word, don't buy second-hand unless you know it. Otherwise, you will regret it. Those masters let you take away the good things, and in two days they will be bad. No way.

Direct non-professional personnel don't have it, but it's better not to buy second-hand ones, after all, second-hand ones are unreliable.

**The selling price is about 1360 yuan, if 700 can reach 9 into a new one, do you say it's worth it, no invoice is not. Whether it's good or bad depends on your own control Will loosen the handle and ride the Tong transport car Try to see if you don't run off when you loosen the handle and ride it If you don't deviate, it proves that the car is okay Warriors I haven't played and don't know the state of the new shock absorber Rely on your own feeling The other is whether there is a problem with the transmission mechanism and the brake Is there an abnormal sound when riding The same is what I know about digging beams I hope it helps you!!

The level of configuration is the first priority, followed by the quality of the hardware.

Thank you for the trouble to adopt!

CPU depends on the number of cores, but now the dual-core of the home machine is enough, and then it depends on the main frequency. The higher the speed, the better. Memory In the past, memory was based on capacity, and now it also depends on capacity, but it is more about frequency, and the second generation 1066 is the highest frequency.

The motherboard is to see the compatibility with the CPU graphics card and the highest capacity of the memory (the key is to see how much the memory can be compatible with, and you can see the upgrade space of this board). Power supply depends on your other power-hungry hardware, but it needs to be 350-550. Home Oh, I said.

Graphics card The key is to look at the core, as well as the video memory and main frequency. Look at the core first, then the main frequency, and finally look at the video memory. The display looks at the size, as well as the contrast, and the point distance, the larger the point distance, the more eye-saving.

Memory, don't buy Kingston's, if you have the money to buy a pirate ship. Jinbang is relatively less fake. It is recommended that the landlord go to buy a computer or save a computer when using a USB flash drive with a little everest and cpu-z, these two small software, when buying a computer, use the software to test the relevant configuration of the computer, at a glance.

Needless to say, the appearance is easy to start, no blue smoke and black smoke, various functions are easy to use, and the driving is powerful.

Don't care about the appearance, even if the shell rots into, it doesn't matter, as long as the strength is good and the smoke is not channeled, it is a good car.

If you simply look at this book, it is nothing more than a few large items: CPU, memory, graphics card, motherboard chipset, hard disk, in addition, this book also needs to consider portability, battery life, etc.; But I still advise you not to consider T61. The current hardware is updated too quickly, and the T410 I bought in June 10 is now outdated.

It is still recommended to consider **, such as: T420, X220 and so on.

As long as you don't buy a discrete display or assemble T61, there is generally no big problem, and it is generally configured around T7300, 1G 80G This is basically the original configuration; Some of them are configured with a single display 140m 2g 320g, but they are not reliable, because when he arrives, the machine will definitely not have a hard disk and the memory is equipped later, so the machine is suspected of being refurbished or assembled; Then there is T61 independent graphics card 140M nivada, this graphics card is bound to break to a certain extent, mainly due to poor heat dissipation caused by damage to the motherboard, general maintenance will be more than 2,300 and it will be broken within a few months, the general treatment is only to replace an integrated motherboard, with my years of experience in selling IBM new and second-hand machines, such a thing will happen 99%; Because the T61 is guaranteed for 3 years, Lenovo is said to have allocated hundreds of millions of machines for the T61 discrete graphics card; Who told him to make his own assertion and ATI parted ways,T61There is basically no problem with the set display It's still more solid,For those who feel that T60 is slightly outdated,And it doesn't require too high requirements for graphic display,Anthology displayT61It's very good,And it's best to be the original memory hard disk,It's also convenient to upgrade if you need to; The last is the basic detection, to detect whether the screen has dead pixels, whether the keys of the keyboard are normal, whether the optical drive reading disk is smooth, the battery has not been replaced, the battery has not been refurbished, the thin capacitance is more than 2500, the thick electricity is more than 4500, and it is easy to lose power during the use of the refurbished and more troublesome; If the keyboard is completely oil-free, it may be a refurbished oversprayed matte paint Although it looks very new, it doesn't feel too good It comes out with a section of oil, and the four corners of the shell have some slight wear and tear The best to pick the shell is new, the four corners are completely wear-free, the shell is very new, and the business only refurbishes the machine that affects the sales of the machine with very poor condition, so that it is easy to sell and new on the surface, but the machine itself is actually more ruthless, and it is better to pick the keyboard shell that has not been refurbished! These are also the basic methods that are universally applicable to picking a 2-handed laptop; Also, T61 is now generally more affordable at 2100-2500; Having said so much, a few books are more comprehensive.,Haha must oh!

First of all, you have to buy an integrated graphics card, and the independent graphics card has a graphics card door problem, and then find a reputable seller.

It's hard to say. Look at the boss to give a warranty for a few years.

My boss gives a warranty of 1 year.

Knows more than I do.

Just check out those forums.

Actually, there is not much need to look at other things. I only know when I use it, because most of them are second-hand on the market.

Since it's second-hand, it means that you value its use, and I use 8700g, which can only be distinguished by disassembling a mobile phone like BlackBerry. It's not a punch, it's better to fly the line.
