Everyone, please help me out with some advice

The configuration requirements for CAD are not high, so there’s basically no need to worry.

For CAD work, it is best to use a graphics workstation. Use laptop resolution?

Ah ah, who can help me? I’m familiar with the computer department. . . . . . . . . . . .

Buy a Dell one; the price is transparent, and the after-sales service is good as well. Engineers provide on-site support, and the LCD resolution can be customized, which is great for CAD work.

The configuration requirements for CAD are not very high, unless you are doing advanced 3D design. If you are in a big city, I think ThinkPad counterfeit models offer the best value; you can get excellent machines for under 7000. Alternatively, you could choose brands that provide good after-sales service in your area.

I also think DELL is good; it’s even cheaper than Lenovo’s.

The configuration requirements for CAD are not very high; for advanced 3D design, it’s sufficient to have more memory. Just buy one so you don’t get scammed; I downloaded something online, take a look. Those who want to buy a laptop, come and take a look. Here are 21 simple steps for buying a laptop: 1. Ask about the prices (it takes about an hour; presumably, the final prices will be those listed on the official website by just a few retailers), and decide where to make the purchase (it’s recommended to spend a month browsing Aibenbang first). 　　2. Start negotiating the price on the premise of getting a new device without any defects; usually check out group purchase prices and aim to get that amount as a discount. If it’s not possible to achieve such a large discount, it’s still acceptable if the difference isn’t too great, after all, you’re only buying one unit. 　　3. After agreeing on the price, preparations were made to have the salesperson pick up the machine. Before that, it was agreed with the salesperson that the invoice should indicate the listed price, with all defects – including both visible and hidden ones – covered at no cost. As the price was estimated to be fairly low, the items included as gifts couldn’t be many; the list below is for reference only: case, mouse, cleaning kit, 3M products, laptop lock, inner bag, camera, laptop speakers, USB-to-dual-PS/2 adapter, USB HUB, memory, etc. Try to get as many of these items as possible; if the salesperson refuses to even include a case as a gift, then the price is likely to be at its lowest. 　　4. Under no circumstances should you pay the money at this stage; it must be checked first before payment is made! ! ! Otherwise, leave immediately. 　　5. It is best to go to the warehouse with the salesperson to pick up the machine; this allows you to choose boxes that look in better condition, and it also gives you an opportunity to assess the reliability of that seller. 6. When the machine arrives, don’t rush to break the seal – check whether the outer packaging of the box is damaged, whether the seal has been torn, and if the surface feels sticky or not. 　　7. Unpack layer by layer, and check the outer packaging seals each time a carton is opened. Finally, ask the staff to wear gloves (if possible) to remove the machine and place it on a stable table, then wait for the machine to be inspected (it’s best not to handle the removal of the machine yourself, as this will make it difficult to clarify any issues that arise). At this point, check whether the items inside the carton match those listed on the packing list. 　　8. First, check the appearance of the machine, focusing on whether there are fingerprints on the casing and screen, as well as any signs of wear at the lock hole. But don’t forget to check whether the serial number on the back of the machine matches the one on the carton! 　　9. On the first startup, press F2 to enter the BIOS and check whether the machine’s serial number matches the one shown earlier. Once it is confirmed, have the technician start installing the system that comes with the machine. New machines (if they come with a system) require that system to be unpacked; the system is not available right from the moment the machine is turned on! 　　10. After the system is installed, start testing it using software. First is the screen; recommended software: (1) NOKIA Monitor Test ； (2) DisplayX (if you don’t use it, be sure to learn the main functions of these software programs while you’re at home). 　　11. To check the hard drive, of course use HD Tune; the most important factor is the amount of time the hard drive has been in use – a usage time of less than 5 hours is the standard for new devices. 　　12. Check the CPU and memory; CPU-Z is recommended. 　　13. Check the keyboard and touchpad (there are software tools for this, but no need to go into details; the best way to test them is by using your own hands!) ). 　　14. Check whether it has Centrino (use Intel’s own software, as other tools are not very accurate for detecting Napa) and the battery condition. 　　15. Check the computer; Sisoft and Everest_Pro are recommended, and compare them with the actual configuration. 　　16. Check the interface. It’s best to carry with you an SD card, memory stick, USB drive, MP3 player, optical discs (and burners if you have one), and any other such devices you can find. Try all the interfaces – many phones come equipped with infrared and Bluetooth functions, so it’s worth checking them out if possible. 　　17. For ovens, try to spend as much time as possible at the place where you purchase the machine; this allows the technicians to divide it into sections according to your needs (8+20+20+30+10+12) ； Replace the built-in XXHOME version with the Pro version ； Use a wireless network card to access the Internet, have the sales staff collect the free gifts as agreed, and then go through the hassle of dealing with those annoying free gifts… In short, keep the device running for longer periods to identify any problems and address them as soon as possible. 　　18. Satisfied; pay and get an invoice then leave. (Cash payments are exempt from fees, so it’s best to go to buy the machine accompanied by a male companion of sufficient quantity and size—to protect you and your money before purchasing, to protect you and your machine after the purchase, and to help carry the bags as well). 　　19. Head to the market and buy some small accessories that weren’t included earlier but are really needed, such as inner bags (I highly recommend one; they usually cost around 35 yuan for generic brands – you can check the price for yourself), adapters, and things like that. Of course, don’t forget to ask the male friends around you to treat you to a meal – you’ve already spent thousands or even tens of thousands; do you still care about just one meal? Besides, if we do it the way I say, it will take at least four or five hours to get it done, and everyone will be hungry by then! 　　20. Don’t get too happy when you get home; take the seven days allowed for exchange to fully understand the machine’s performance, and if there are any problems, contact JS right away! 　　21. Enough talking – I wish everyone can find a great book that meets their expectations. This post was last edited by Fishing for big fish on 2009-4-20 16:55]
