Go buy this book what should I check and what testing tools do I need to bring Please be specific, t

CPU-Z test CPU model, GPU-Z test graphics card core, Master Lu measures everything screen dead pixels, hard disk power-on time, battery loss, hardware production time, etc., ** to the U disk. Just buy it and test it.

Look at the price positioning. What do you need to do with it?

It is recommended to buy HP ASUS from these big brands. Of course, js. is not excluded

Yes. I've bought a lot of computers. There is such a little experience.

If you really don't understand, it is recommended to buy Lenovo. Lenovo's original thinking is very thoughtful, which can save a lot of trouble.

Generally, there is no problem with the hardware of this book.,Buy it from a regular home appliance.,Suning A Guomei.。 Just buy it. Look at the configuration must suit you.

Before buying a computer, the landlord first went to the Internet to check the information, and had a clear understanding of the grade and configuration he wanted to buy, and then went to the store to be relatively targeted, and he was not so passive when bargaining.

The choice of computer depends mainly on your needs

I am most afraid that the screen will have bright spots. It's annoying to copy people.

I'll tell you a good and free software that specializes in detecting computers.

Master Lu (z**) is a detection software that scares many profiteers.

Try it !Absolutely.

The best way: the computer runs for three days in a row, and it can be returned directly (within the return period) The configuration will not be a problem, I have not seen a few problems, you want to pay more attention to see the seal, whether there is a removal or the seal is not neat.

When you buy it, you will know that many precautions are useless.

The models you want to buy are all set, what else to test, there are evaluations on the data network!

These two modelsY450 screen is 14 inches,Y550 screen is inches,That's the difference,Generally, if you often carry it around, buy itY450,Y550To be honest, it looks a bit big and stupid。

The difference between TFO PSE TSI PEI is that the CPU is different: TFO is T4200, PSE is P7350, TSI T6400

PEI P8600 Of course, the higher the number, the better, but the number of P is better, because of the energy saving of P.

In short, the graphics card you play the game Y450 550 is enough for 130M top-of-the-line graphics cards.

Look at your personal preferences on the screen, and you can see which one you like when you go to the store.

As for the CPU, the personal feeling of T4200 is enough to use the double-open World of Warcraft or something, there is no problem at all, hehe**It's cheap, the most cost-effective, I recommend youY450A TFO white is now 4800, remember that Y450 has a A behind it, and the white one, the white graphics card is good, if you like the gray one, buy TSI.

Of course, you tested it yourself, do you believe the merchant when it tells you that there is no problem?

First of all, pay attention to the seal of this box.

Secondly, bring your own detection software.

Bring your own, preferably. If you don't know how to do it yourself, find a computer whiz to help you get it. Otherwise, it will be very troublesome.

Suning Gome is not afraid, and the others should be careful. The computer city should be brought by itself.

1. Outer packaging and contents of the box.

First, check that the outer packaging is intact. For many brands, the packaging is sealed. Therefore, the first step is to check the outer packaging for signs of opening.

2. Check the serial number.

Once you've checked that everything is correct, it's time to take a closer look at your laptop's serial number. This step is very important for friends who choose foreign brand laptops, if there is a situation where the serial number is inconsistent, it may be parallel or assembled goods.

3. Check the appearance of the book.

Visual inspection is very necessary, because the current national three-guarantee law on electronic products is relatively vague as to whether it can be returned or exchanged due to appearance problems.

4. Interface check.

After the appearance inspection is confirmed that there is no problem, the following is turned on for various special tests of the notebook, which require the use of some professional testing software, so prepare these software before purchasing and store them on the USB flash drive.

5. Detection of LCD screen.

The special detection of the LCD screen is mainly focused on whether there are dead pixels, and we can use nokiatest software to check the detection of this dead pixels (see the figure below), this software does not need to be installed, and the file size is only about 580kb.

Some things that should be paid attention to when starting up the inspection box:

1. When unpacking, check whether the packing box has been opened, even the bottom should be checked. If there is a seal on one side that can be seen to have been affixed later, then the machine must have opened it before.

2. Compare whether the serial number of the host BIOS is consistent with the serial number of the outer packaging box and the serial number at the bottom of the machine.

3. Check whether all kinds of accessories are complete (you can use the packing list to check whether the accessories are complete), whether the serial number of the accessories is consistent with the packing list, and whether there are signs of damage or use. In addition, before buying a machine, it is best for friends to log in to the official ** of the model you are interested in, and inquire about what accessories there are for this model.

4. Check the various equipment that can be removed from the base, if not, you can ask the merchant to help you take it down, and check whether the serial number is consistent with the packing list (some machines do not have a serial number on the box).

The next few software, test whether the display has bright spots, whether the hard disk has bad areas, CPU, mainly these several, there are special test software.

Check if the appearance and accessories are complete.

Don't be so suspicious, there are still many good people, but remember to ask for an invoice or something. It depends on their credibility. I'll believe them, hehe.
