(I think it is useful to you. You must step on the footprints ^_^ welcome to comment)

The bottom of the IBM ThinkPad laptop is the product model and serial number. The last digit of the product model is "C", indicating "China. You can enjoy the three-year global warranty service, so you don't have to worry about bringing it abroad. If not, it's just a commodity.

I. Check whether the accessories in the packing box are complete against the IBM packing list

An IBM random packing list will be placed, and all the accessories in the box will be listed on the list.

1: One Machine
2: one battery
3: one set of adapters: Three are English, Hong Kong and Singapore goods are like this; two are American, and the United States goods are like this.
4: a telephone line connected to the Internet by a cat.
5: a set of manuals, most of which are T40. IBM uses the same set of manuals for T40, t41, t42, and T43 to save costs.
6: Red Hat two, the original configuration is replaced when cleaning dirty.
7: one fixed screw of the optical drive: used to fix and swap the optical drive.

Ii. Check the appearance and whether there are any scratches.

Iii. Boot advanced bios, verify Sn and UUID

Press F1 to enter the BIOS. First, check the general configuration, clock speed, memory, and two key numbers, Sn and UUID.

Example of the IBM ThinkPad T43 BIOS:

System-unit serial number 187124uab1234: 1871 is the model. 24u is the model, and ab1234 is the serial number of the fuselage. The Sn number is the unique serial number of the machine. The Sn number found in the BIOS must be matched with the packing box, on the back of the machine, and tested by software.

The UUID number is the serial number of the motherboard. It is displayed only in the bios and the packing box. If the machine motherboard is changed, the uuid number will change.

4. Start to enter the system and test the screen.

Use professional testing software, such as nokiatest, to switch the screen to the full screen color.

V. View battery charge times

Because domestic friends like to have no bad spots on the screen, both Hong Kong and US will start the test point, but in general, the battery charge times are 0 or 1. If it is an old battery, this step cannot be escaped. With the current technology, no master can refresh the number of refresh times.

6. Check the online Warranty Period and the attachment number.

IBM ThinkPad warranty search site: http://www-3.ibm.com/pc/support/site.wss/warranty/warranty.vm

After login, as shown in:

Enter the Machine Model in the type column, for example, 2668.
Enter the machine Sn in the serial # column, for example, L3 #### P

Then click continue, and the warranty information will appear, for example:

Warranty Period and place of sale for machines.

Next, click View parts lookup results of this system)

The information includes the numbers of most parts of the machine. The numbers can be checked against the numbers displayed by the parts themselves. If the numbers are consistent with those displayed, the numbers are displayed as yes.

Note: Because machines and packing boxes are separated from the customs, one-to-one packing on the Chinese mainland will inevitably result in wrong installation of adapters and telephone lines, the numbers and website display numbers of these two parts may not match. In addition, the hard drive, memory, optical drive, and battery Number of the machine are all correct.

This number is the factory number provided by IBM for its own accessories. Other test software cannot be tested.

Okay. You can purchase it with confidence after completing so many tests.
