~ ~ since it is a business ~ then we must pay attention to safety, confidentiality and convenience.
ThinkPad still follows IBM's classic eternal black.
It reflects the feeling of business people's stable atmosphere.
Still retains a simple and clean design style.
Fingerprint reader is first-class in the industry.
The shell is made of aluminum-magnesium alloy, weighing about 2 kg and measuring about 12 inch.
There is also the famous little red dot, the pointing stick in the center of the notebook keyboard, which acts as a mouse.
It is very convenient to use, and you don't have to carry a mouse all the time.
Then there is the hard disk data recovery function, poisoning crashes, system crashes, and the data in the hard disk can be saved.
There is nothing wrong with the configuration, except that you can't play large games because it is an integrated graphics card.
Prices are all above 12000.
Finally, Lenovo's after-sales service is quite good, with many national outlets covering all regions.
Finally, I would like to recommend some models to you. Now the big series is T400T400T500. There are different models under these three series, but the prices are different. Just go directly to the Lenovo store to buy it.
The following are some related technical materials.
Magnesium roll cage
ThinkPad is the first magnesium anti-roll frame, which is integrally formed. Its design principle comes from the anti-roll frame of Formula One racing car. It uses carbon fiber, glass fiber and magnesium alloy to stabilize the internal key components, thus reducing the damage of accidental drop and vibration to the notebook and protecting data security. The roll cage can reduce the bending degree of the system motherboard and improve the durability; The extra hard disk armor layer increases the seismic performance; Strengthen thermal insulation protection to make the machine more comfortable to use; Strengthened the protection of optical drive. The test shows that this new design reduces the impact force on internal components by 30%, forms a golden bell jar to protect internal components, and improves the stability of the system. Compared with ThinkPad system without roll cage, the component deformation of ThinkPad with roll cage is reduced by 4 times. According to the report of International Magnesium Association, the strength-toughness/weight ratio of magnesium alloy is the best among general structural metals.
Little red riding hood
Little Red Riding Hood, scientific name TrackPoint, as the iconic feature of ThinkPad, is not only small in size, but also can be easily placed on keyboards of any size. And it is simple and flexible to use, so it is the best equipment to replace the external mouse in notebook computers. TrackPoint is located in the center of ThinkPad keyboard, so users can operate it conveniently without leaving the keyboard. Compared with the touchpad, another control device in the notebook computer, TrackPoint does not need to move your fingers back and forth during operation, so the click position is more fixed and the control accuracy is higher. TrackPoint has two very convenient functions, which make it as easy to use as a mouse. One is the "center button", which can be used to select the scrolling function and enlarge the display function of TrackPoint. As long as you click the center button, you can move the scroll bar no matter where the pointer is; The other is the "press and select" function, that is, TrackPoint can not only support moving the cursor, but also realize the function of clicking or double-clicking the left mouse button, also known as "keyless mouse".
Due to the development of the market and the participation of various consumer groups, ThinkPad later designed three Trackpoint according to the ergonomic design concept: classic hat, garden side hat and floating-point hat. It shows that ThinkPad fully considers the needs of different people in its design, which is people-oriented and does not conform to historical achievements.
Little red dot is an important patent of ThinkPad! In Lenovo's acquisition of IBM's personal PC business, ThinkPad applied for more than 2,200 patents in the United States, accounting for 20% of the total acquisition amount. (At present, global patents are legally recognized only when they are applied in the United States), of which little red dot patents account for 65,438+0% of the purchase price.
APS-hard disk protection technology
The APS hard disk active protection system consists of an acceleration sensor chip embedded in the motherboard and vibration prediction management software pre-installed in the operating system. By monitoring the vibration and impact of ThinkPad notebook at all angles, that is, monitoring the changes of horizontal and vertical acceleration, it is decided whether to withdraw the hard disk head from the working state to the head parking area, so as to reduce the damage to the hard disk caused by the impact and protect the hard disk and the data in the hard disk. Among them, the hardware layer is used to monitor the horizontal and vertical acceleration of the notebook, and the software layer receives the corresponding signals of the acceleration sensor chip, and judges which ones are harmful to the hard disk and which ones are moving regularly through analysis. The vibration prediction management software will ignore the regular movement that does not damage the hard disk. For the movement that may cause damage to the hard disk, the information will be immediately transmitted to the main hard disk, and the nose will be quickly retracted to the parking area within 500 milliseconds. So as to effectively avoid the damage caused by the collision between the magnetic head and the disk. This technology can improve the safety factor of hard disk and user data in it by four times.
ThinkPad's unique hard disk shock absorber, like a car shock absorber, improves the impact resistance of the hard disk. Compared with the simple notebook hard disk protection pad, this technology can improve the hard disk protection ability by 30%.
Rescue and recovery-rescue and recovery
RnR, Emergency and Recovery System (Rescue and Recovery)
The user interface of RnR is very simple, with enough hints and explanations. All user interfaces (menus and parameters) can be customized according to user requirements. For example, set the system to automatically back up regularly.
RnR can repair Windows and save data when Windows can't enter, and even send and receive emails online and visit websites for help. The generated backup can be stored on external media such as CD\DVD, USB hard disk and network. Backup can be set in the background, with low CPU utilization and no interruption to the user's current operation.
