1. Baosteel cbw1 and Baosteel JBT refer to the call warrants with the underlying securities of 600019 Baosteel, CBW refers to the equity warrants, and JTB refers to the covered warrants
nowadays, warrants in the market are all by-procts derived from related separated convertible bonds. In fact, warrants are equity warrants, which can increase the share capital of listed companies and are distributed by listed companies to relevant securities holders; In addition, there is another issuance method. This issuance method generally refers to the issuance of relevant warrants of the listed company by a third party other than the listed company. This warrant can not increase the equity nature of the listed company. Generally speaking, this issuance method is that the relevant innovative securities companies can issue relevant covered warrants as issuers (this issuance method is very common in foreign countries), However, the Securities Regulatory Commission does not allow the issuance of such warrants. However, in the near future, the emergence of such warrants in the securities market will be a major trend. Generally speaking, these warrants are not distributed, and investors are required to buy them from the relevant issuers. These warrants can be traded in the market. In addition, the issuers should provide a trading quotation as a market maker, Because this kind of warrant involves many related problems, there are no related warrant varieties in China's relevant warrant market, but the relatively new issuance conditions are only limited to the emergence of listed companies issuing their own related warrants
in the past, covered warrants were issued by major shareholders of relevant listed companies as issuers to tradable shareholders as consideration for share reform e to share reform.

2. It is likely that there is a problem with the software, resulting in the black screen of the system.
3. Maybe it's a system problem. You can redo the system. If it still doesn't work, maybe there's something wrong with the hardware, such as the graphics card and the driver. You can redo the driver. It may be that the memory mole is loose. Check if it is loose. Pull it out and plug it in again! This kind of problem can only be eliminated bit by bit!
4. Press the restart key, try to press F8 to enter safe mode, try the last normal start
5. Unknown_Error
6. This may be a problem with your installation package, resulting in the normal download of the installation software. If you want to download the regular software installation package, you can download it with app bora. This is what I use myself. The downloaded software has never encountered this problem
you can download the PC version on your computer to connect with your mobile phone, or you can download it on your mobile phone, and then enter the main interface of the software. You can directly find the application or game you need in the search box, or you can search according to the type, which is very convenient. Just download and install it after you find it
this should not happen again.

7. Generally, there are four kinds of black screen faults:
one, all black. The host and display (including indicator light) are not on
Second, the indicator light of the display is on, the indicator light of the host is not on
Third, the indicator lights of the display and the host are on, and the switching power supply cooling fan also rotates normally, but the display does not display
four, the dynamic black screen will be displayed when the machine is started, but it will not be displayed after a while
what kind is yours? Compare and make it clear
that may be because the display signal line or power line is not connected properly, and the brightness contrast knob is accidentally & quot; Shut up;, If the hard disk signal cable is inserted reversely or only one row of pinholes are inserted, it may be that some metal material falls on the motherboard and causes a local short circuit, or the memory mole is not inserted properly. In a word, take out the chassis, clean it up, pull out those wires and insert them again. Pay attention to plug them well, especially the memory, There are two main reasons for computer black screen at present, one is hardware failure, the other is software conflict, and the difference between the two mainly lies in the location of the black screen, that is, the black screen occurs when the machine is started, or the black screen appears in the process of use after the machine is started normally
of course, whether it's hardware failure or software problem, it's not isolated in a sense. Try to solve it along the following way, I believe that the black screen will be properly solved soon
black screen hard damage
when the "black screen" suddenly appears after power on, readers should first listen to whether the PC speaker in the computer has alarm sound. If the PC speaker gives an alarm sound, then we can preliminarily determine the hardware parts that may have problems according to the length of the sound. For example, if the alarm sound of PC horn is one long and four short when the computer is turned on, then according to this prompt, it is easy to judge that the problem is on the display card. If so, readers can open the chassis to see if their display card is firmly inserted. If you feel some looseness, please pull out the display card, insert it again, and then fix it with screws
if the problem of plug-in method is eliminated and the card slot is relatively firm, you can pull out the display card and try to replace it with another slot on the motherboard. If the user's display card does not belong to PCI, but is a new AGP slot board, and there is only one AGP slot on the computer motherboard, you can try another AGP slot on the motherboard to eliminate the physical failure of the display card. If the display card is tightly inserted and the physical fault is eliminated, another possibility is that the "golden finger" of the display card itself has a problem in normal contact. If this is the case, you can pull out the display card again, and then find a clean rubber to wipe back on the "golden finger", because this kind of "golden finger" poor contact problem is mostly caused by some dirty things on it
if the alarm sound of the PC horn is not one long or four short when the computer is turned on, but a sudden short call, and at the same time, there is a black screen, then it can be roughly judged that there is a problem in the contact of the memory of your computer according to the phenomenon. The solution to poor contact is basically the same as the display card, which is to pull them out and then insert them again. Pay attention to insert them to the end, and clamp the clips on both sides of the memory slot firmly
the SDRAM slots on some motherboards are troublesome, because most of the slots on these motherboards are made very tightly. If users encounter this situation, they must not force them to use hard. They can hold the bottom of the SDRAM slot on the motherboard with their fingers, and then press down the memory with their thumbs. After hearing a slight sound, they can prove that the memory has reached the bottom, Finally, fix the memory with the clip
there are also some black screen phenomena, the computer will not alarm. At this time, the simplest is to analyze the specific problems according to the mathematical "exclusion method". First check whether there is a problem with the power wiring board, remove the relevant supporting parts of the computer, and replace with some other equipment that can be used to check whether the power wiring board works normally. If there is no fault in the power wiring board, then check whether the connection between the computer power supply and the motherboard is normal according to the normal procere, that is, check whether the motherboard power supply is normal
if the socket is not connected incorrectly, you should check whether the power supply is burned. If the power supply is burned, the power fan will stop running. In some early computer cases, the power supply is often insufficient. If you suspect that this is the case, please pull out all the power cables of hard disk, optical disk drive and floppy disk drive, and then restart the computer. After the power consumption is greatly reced, see if this situation can be solved. If the problem still can't be solved, please exclude the accidental damage of BIOS by CIH and other viruses, and whether there is bad contact or short circuit of soldering head on the motherboard
in addition to the above, with the continuous improvement of the main frequency speed of CPU, the power supply plays an increasingly important role in the whole PC power system. Some people describe CPU as the heart of a computer. Maybe for a long time, we all care too much about whether the heart is healthy and powerful, but ignore the chassis power supply that can provide power and energy for the heart. However, e to the lack of power supply, it may also cause the phenomenon of computer black screen. The symptom is that the power supply fan of the chassis can be heard to start normally after the machine is turned on, and the "didi" sound of system error is not heard, but the machine does not work, there is no power on self-test process, and the display is black. If the power is cut off and all cards and memory are plugged in and out again to make sure that all cards or components are not loose, it is mostly caused by insufficient power supply
the author strongly believes that for the sake of your health, you should not neglect the chassis and power supply when purchasing a computer. Buying a power supply with a rated power of more than 250 watts is a kind of love for your machine. Here's another point to note. At present, many power supplies with rated power of 250W in the market can't meet the requirement at all. This leads to another suggestion that we should take care of famous brands when buying power supplies. The brand is a powerful guarantee for the safety of your machine at this time. If you have more peripherals installed on your machine, such as al hard disk, al CPU, al CD-ROM drive, SCSI card and so on, you'd better find a higher power (300-400w) or server power supply. As for the users of P4, Thunderbird and geforce3, they must use more than 300 watts of power supply, otherwise, more troublesome things will emerge one after another than the black screen
black screen software is not good
of course, the black screen phenomenon is mostly caused by the hard damage on the PC, but it is not absolutely so. Sometimes soft damage may be easier to deceive users. In the process of using the computer, some black screen phenomenon may also be the soft fault after entering the Windows 98 / Windows / Windows 2000 or even the Windows XP system (but the author has not found the black screen fault of Windows XP at present, but since there is no final conclusion, we have the right to consider it)
if the user finds that after the machine is assembled, there are always inexplicable problems in the process of installing the operating system and other software, or even sudden black screen crash. Here we need to rule out the cause of the virus, because there are many cases of black screen caused by the virus ring the operation of the system, but the only solution is to kill the virus. There is nothing more to say. On the contrary, we should pay more attention to the error or black screen of the program. The most obvious problem here is the program running failure caused by the hardware driver problem. This kind of problem frequently occurs in some 3D acceleration display card, PCI sound card, network card, SCSI card, raid card and other third-party boards, and the most obvious manifestation of this kind of problem is that the application program, game software and other running process frequently crash and lead to black screen
for example, when playing ngeon Guardian II, S3's diamond Viper 770 / geforce 2pro acceleration display card is often rejected by the game (the display card is not recognized), and even the game will give up hardware acceleration and switch to software effect. The main reason for this problem is that the game source program ignores the power of the standard 3D acceleration chip or the more high-end, updated non mainstream 3D acceleration chip, so the game itself is not ideal in terms of hardware support, which also affects the performance of the proct. Another example is PCI sound card, PCI network card and so on. Because of the conflict between the driver and the system application program, the machine will appear a sudden black screen or restart in operation. Readers can solve this problem by installing an updated version of the driver.

8. Virus factors or software incompatibility may cause black screen
so first of all, has the software been used to kill the virus? Second, whether the computer returns to normal after the software is removed (generally, it should be removed in safe mode).

10. There's something wrong with the system. It is too laggy to replace the verified system disk reload system directly, so that it can automatically and smoothly solve the problem of software opening in the system, which often shows no response. With U disk or hard disk, these are OK, and the installation speed is very fast. But the key is: to have a good compatibility (compatible with IDE, achi, raid mode installation) and can automatically permanently activate the system disk, which can automatically install the machine hardware driver sequence, this can automatically and smoothly re install the system. The method is as follows:
1. U disk installation: with UltraISO software, open the downloaded system installation disk file (ISO file), execute "write image file", insert the U disk into the computer, click "OK", and wait for the program to be executed. In this way, the U disk for starting and installing the system is ready. After booting the machine with the U disk of the system, the U disk can be installed, The system can be successfully re installed;
