I recently wanted to buy a book, and I took a fancy to the ThinkPad SL400 2743CE3 or 2743 AWC, but I

His episodes are almost sufficient. If you don't play games and don't do graphics processing, the difference is not very big, and the so-called independent graphics card is just an entry-level graphics card. Mine is a solo display, I don't play games, and my roommates say I'm a waste.

The main differences between SL and the previous IBM are the lack of magnesium aluminum roll cage (which will be less resistant to bruises) and the shrinkage of heat dissipation, as well as the lack of keyboard lights (in fact, I think this is very practical). The layout of the keyboard is also different from the other series of ThinkPad, which is closer to the keyboard layout of Lenovo's own machine. So netizens said that SL has changed its taste, and it is a hybrid ...... Lenovo and Thinkpad

Check the machine mainly to see that his outer packaging must be in good condition, after dismantling the surface of the piano paint to see if there are fingerprints, and then check the edges and corners of the machine, especially the fan part of whether there is dust, the left side of the machine heat dissipation port close to the left palm of the graphics card label There is a slot, be sure to push the slot with your fingers, pull out the card slot to see if there is dust. These are the most basic ......My book has just cleaned the card slot not long ago, and I just looked at it, and there is already a backlog of dust, which I personally feel is very valuable.

Finally, pay attention to check the screen, dead pixels and light leakage of the machine, and the common problems of SL ......It's OK if you watch out for the bad spots, and the light leaks ......It's all too common.........

Of course, it's good to be alone.

It can be divided into four discs, and the C disc is used for the system.

Hello, to help you query the memory of your machine is the model: 667MHz DDR2, it is not recommended that you install DDR3 memory, so as not to be incompatible.

The number of memory slots configured on your computer is: 2, and the memory specification is: 2G. The maximum memory capacity of a single memory slot is 2 Gbit/s, and the maximum memory capacity of a whole machine is 4 Gbit/s.

Installation suggestions: 1. It is best to maintain the same specifications as the standard memory, and there are not too many requirements for the brand, so it is recommended that you install regular manufacturers to produce memory, such as Kingston, Samsung, etc. In order to rule out compatibility issues, it is recommended that you bring the machine with you when you buy it, and then add it after the actual test can be used normally.

2. If it is a memory with different specifications of the installed and pre-installed memory models, it may be used at a reduced frequency after installation, and there may be incompatibility problems, if you want to install a memory that is different from the pre-installed model, you need to carry out the actual installation test, if the system can be identified normally, it is recommended that you buy again.

3. In addition, it should be noted that the operating system will also have restrictions on memory recognition: if it is a Windows 32-bit operating system, it can generally only recognize about 3G memory size due to system limitations. If you need to identify 4GB or more of RAM, it is recommended to replace the 64-bit operating system.
