Some time ago, the office notebook was always the ThinkPad L450. The one that broke the news before the aunt.
Later, relatives at home had to configure the laptop to go to college. Simply sent me this station. Anyway, I still have a surface pro3. In fact, after the home was equipped with a desktop computer, sp3 was idle for a while, and it was a bit unaccustomed to use it again.
Because of my poor use of habits, chrome has opened a tab page is not willing to turn off; sometimes work when you need to switch between multiple software, so it will open a number of software; chat software, qq, WeChat, Want Want, nails must be Open. In fact, sp3 configuration and the above L450 is similar, but this machine is a bit bad, heat is too bad, after a while you can hear the sound of the fan, touch the backplane, hot, and program switching will also Caton. I thought that it would be no good. If we had to change the configuration of a higher one, it would make it easier to work and make more money. It would be a little exciting to think about it.
PurchaseIn fact, choosing a computer is quite simple. Look at the current screening conditions of JD. Finally, you can always select one or two machines that meet the conditions.
Here to talk about the purchase of the landlord. The primary purpose of the replacement is performance, and after a few low pressure cpu, the landlord still feel a bit weak, so cpu this piece directly selected i7 standard pressure. At first glance is the game book, and then use the classification and then choose the ultra-thin book, the result is only two, Dell XPS, ThinkPad T460P, you see how simple a thing. I have no love for ThinkPad, and it can be said to be a history of blood and tears. Not much to say, direct XPS15.
After selecting XPS15, the landlord only thought of a hardware person concerned on Weibo who sent XPS15's purchasing and upgrading experience, and quickly found a reference. There are four main configurations.
According to the proposal, the minimum match is not necessary, the highest match is not necessary, and the difference between the middle two paragraphs is 3,000, but actually only the memory, ssd capacity and battery, and these three, follow-up can be upgraded on their own, it is clear that their own upgrade More cost-effective.
According to my own experience, the high resolution of surface pro3 did not bring me a lot of good experience, touch screen is rarely used, so high 4k touch is not necessary for me. And I was looking for the i7 book. Naturally, the i5 processor is not.
Then the order plus 2 years of accidental insurance, before always seeing that Dell can find customer service sales to discount, I also followed it, the result did not succeed, just said that will give that backpack, mobile power. The total price is 12,507.
In fact, see Aunt Zhang, naturally know that Dell's notebook will be more cost effective to sea up, but taking into account the expensive, and the cycle is longer, the tax is uncertain, the discount appears from time to time, and many other factors, the landlord chose the BNM , spend more money to buy a peace of mind. This differs from person to person. Open box below
Out of the boxOriginally, I was on a single Saturday, and I had an abacus for arrival on Monday. As a result, I did not know until delivery. In that case, it was received on Sunday and it was deliberately taken from the company.
Big box
There is stuffing inside, a paper box folded out
efficiency
The box is open, it is full of textured black carton
Open, see the real body, silver body, a layer of plastic film, and this is the same as Apple products.
Look at the power adapter, a bit like the current charging treasure
D surface, a row of cooling holes, two feet, should be able to maintain a good heat dissipation. The XPS brand has two screws in it.
In fact, it is still quite thick.
Interesting power adapter
The above is the photo of the box after the company got the goods. The following is taken at home, but it is not very good anyway.
A surface, simple
B surface, ultra-narrow frame, the effect is still very good.
Look at the status of the light screen
On the C-side, it is not equipped with a numeric keypad, which results in relatively large unused space on both sides.
D surface, once made it.
Then the first two were compared with the 15-inch Shenzhou I had used before. Shenzhou's interface dust was too lax to clean up.
After booting, there will be a self-contained software, briefly introduce this machine, recommend a little accessories, but the open link is a foreign mall, but also do not know how.
But it does not matter, anyway, change the hard drive, but also reinstall the system, boot just to activate the Win10 Home Edition comes with the home version. It will be activated automatically when you install it again.
upgrade RAM
This is the simplest, most of the notebooks that can open the back cover, the memory is directly exposed, and does not limit you to move it. Because of this, many times the 4G memory notebook is more cost-effective. I bought this version of the 8G memory, in fact, to say that my daily use, it is certainly enough, but the bigger is always good, although I did not directly on the 32G. Kingston's direct purchase of DDR4 2133 8G two sets.
Jingdong is also quite interesting, this piece of memory, single buy is 299, mobile phone exclusive price is 298, diamond membership price is 297, which is equivalent to I bought two singles is 594, and the set price is 599, The mobile phone exclusive price is 598, which is more expensive than buying two.
battery
My xps15 battery is 54Wh, there is a hard disk next to the battery, you can add a hard drive, because I have a mobile hard drive, and this computer is mainly used for office use, it does not care about storage space, even if there is a demand In the later period, it can be changed back again. In short, it is free to match. The battery capacity of the xps15's large battery version is 84Wh, so you can directly search for “xps15 84wh†on Taobao. Tmall only has one store.
hard disk
XPS15's own hard drive is m.2 pcie solid state hard drive, said the upgrade guide mentioned above was not listed Samsung SM961, so the landlord Taobao search on it, and some have sold. 256G is about 1200, 512G is nearly 2,000, weighed about the capacity and price, and ultimately compromised the capacity, choose 256G, capacity is not improved compared to the original match, promotion is only reflected in the speed, this point later Look really sorry.
Things are purchased on Saturdays, the memory is Jingdong delivery, the next day, the battery is delivered in Beijing, the next day is also arrived, only the hard disk is shipped in Shenzhen, and the store made a SF special, went four Genius to Beijing. So fast mid-Autumn Festival, hard disk to hand. The following simple to say disassemble replacement process.
The XPS15 is still very easy to disassemble. It uses the overall D-surface design similar to the macbook, but only two are hidden behind the nameplate. Compared to the previously disassembled vostro series, it was a conscience. However, it is almost worse than my God boat, because the God boat does not need to screw down.
A total of twelve screws, all disassembled, can be opened directly. The internal structure is still neat, that is, the sticker is a bit mad.
After opening it is like this
Look at the memory that will be replaced
hard disk
Battery, obviously longer
The process of removing the installation is very simple, not to mention, look directly after the effect of loading it.
Rear cover, screw on, reinstall the system.
Here encountered a problem, directly replaced by the hard disk, direct reloading is not recognized, I made a pe disk with a USB flash drive, and then go into the disk partition, assign the drive letter, change the partition type to GPT
Into the installation process, there is an error message, can not be installed to the selected location, this time you need to go to the official website to download an Intel raid driver into a USB flash drive, and then point load the driver, navigate to the drive directory, install it again It is installed, and this time it cannot be formatted in this interface, otherwise you have to reload the driver. Did not take pictures at the time, borrow a network map
At the end of the successful installation, after entering the system, we tested the speed of the hard disk, which is faster than before.
This is the original
This is now
experience feelings
A few days later, this book's cooling is possible. The speed is not enough. The 1080 screen is just fine. The narrow border looks great and there is a visual shock. The only thing that is not satisfactory is the keyboard. The keystrokes are a little short. The hand feels a bit short. Typing time is longer and the power button feels not very good. When you turn on the computer, the feedback is not enough to force. You can't be sure whether it has been pressed. . On the whole, this book is still satisfying to me, and the price/performance ratio is much higher than that of sp3, which I bought more than once in the previous year. And it's nice to be free to upgrade.
Upgrade suggestion: If you don't have high requirements for hard disk speed, you can rely on the budget. Memory can be directly on the 32G, once in place. If you have a warehouse, look for a personal choice. I don't need it, so I upgrade my battery.
Speakers are one of the most common output devices used with computer systems. Some speakers are designed to work specifically with computers, while others can be hooked up to any type of sound system. Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener.
Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver. This input may be either in analog or digital form. Analog speakers simply amplify the analog electromagnetic waves into sound waves. Since sound waves are produced in analog form, digital speakers must first convert the digital input to an analog signal, then generate the sound waves.
The sound produced by speakers is defined by frequency and amplitude. The frequency determines how high or low the pitch of the sound is. For example, a soprano singer's voice produces high frequency sound waves, while a bass guitar or kick drum generates sounds in the low frequency range. A speaker system's ability to accurately reproduce sound frequencies is a good indicator of how clear the audio will be. Many speakers include multiple speaker cones for different frequency ranges, which helps produce more accurate sounds for each range. Two-way speakers typically have a tweeter and a mid-range speaker, while three-way speakers have a tweeter, mid-range speaker, and subwoofer.
