According to ZDNet reports, amazon is expected to be on September 6, at the conference launched two paragraphs tablet PC keyboards shop
keyboards shop, which one will support advertising, price may be less than us $175.
The amazon will be on September 6, in Santa monica, California at the conference, launched the second generation Kindle Fire tablet PC and a new generation of e-book reader Kindle Touch. The Wall Street journal quoted unsubstantiated news reported that the acer aspire 3620 laptop keyboard second generation Kindle Fire may have seven inches and 10 inches two versions, one version will support advertising, amazon the move is to reduce the cost.
Amazon last week also announced the first generation Kindle Fire tablet PC has been sold out. Kindle Fire 2 many parameters details have exposure,acer aspire 4810t laptop keyboard one of the biggest improvement is from the screen resolution before 1024 x600 pixel ascension to 1280 x800 pixels, this not only help to improve the readability of the font, still can make Kindle Fire 2 broadcast hd video.
In addition, it is not clear whether the amazon will cut Kindle Fire ($199) price, so that with Google Nexus 7 and rumours of 7 inches iPad portal version competition. The price of 199 dollar Kindle Fire in the announcement of a competitive is considered, but in Google introduced Nexus 7 after, the first generation of Kindle Fire price will no longer have an advantage.
Google and amazon all don't hope through the hardware acer aspire 5670 laptop keyboard sales to make money, but to drive by the hardware ebook, movies, music, application etc to increase sales revenue. Amazon CEO Jeff Bezos (Jeff Bezos) in announcing the first generation Kindle Fire sold out news, said to be "the best content of ecological system" have hailed the success of.
The personage inside course acer aspire 5741 laptop keyboard of study is expected to, amazon is likely will be released two paragraphs 7 inches Kindle Fire 2, one is priced at $199, and support advertising version of lower price, may be less than $175.

Solve the CD writer meet failure
A common faults: installation CD writer unable to start the computer
First cut off the computer power supply,sony udqf2ph22cf0 laptop cpu fan open the case shell check IDE line is insert completely, and to ensure the PIN - 1 PIN position properly connected. If the CD writer and other IDE equipment Shared a IDE line, should guarantee the two equipment cannot at the same time setting of "MA" (Master) or "SL" (Slave) way, can put a set to "MA", a set to "SL".
Common fault 2: use simulation burn success, actual burn failed
CD writer provide "simulation burn" and "burn" the order difference lies in whether hit laser beam, and other operations are exactly the same, that is to say, "simulation burn" can test source CD is normal, hard disk rotational speed is fast enough, enough free disk space and environment situation of the burn, but can't test to burn blanks whether existence problem and CD writer laser read-write head power and disc is matching, etc. In view of this, explain "simulation burn" success, and really burn failure sony udqf2ph52cf0 laptop cpu fan that CD writer and blank disc of compatibility between is not very good, can use the two kinds of ways to test the:
1. Reduce CD writer's writing speed, it is recommended that the following 2 x;
2. Please change another brand of blank discs burn operation. This kind of phenomenon appeared another reason is that laser read-write head power asus a6000ga laptop cpu cooling fan attenuation phenomena cause, if use the same brand of disc burning, in a period of time before all normal, and is likely to read/write head power attenuation related, can send relevant manufacturer maintenance.
Common fault three: can't copy the game CD
A few large commercial software or game software, in the production process, the CD blanks made protection, so in the replication process, will be unable to replicate, leading to burn process error occurs, or copy the later can't be used normally takes place.
Common fault 4: burn CD music cannot normally broadcast
Not all audio equipment can normal reading cd-r blanks, most of the CD machine can read normal cd-rw makes blanks content, so best don't use DVD burner to burn a CD music. Additional, still need to pay attention to is that burn CD music, must want to accord with CD - DA file format.
Common fault 5: the ones in the process of CD, can appear sometimes "BufferUnderrun" error message information
"BufferUnderrun" error message information means buffer underload. General in the burning process, to burn data need by the hard disk
A IDE interface transfer to the host, and then via the IDE interface transfer to CD writer of the cache (BufferMemory), and the last CD writer put in toshiba qosmio x300 series laptop cpu cooling fan storage
In the BufferMemory data information copied to the cd-r or cd-rw makes blanks, these actions must be continuous, absolutely can't interrupt, if any a link to a problem, can create CD writer cannot normal write data, and the emergence of buffer underloaded error message, which is disc scrap. The solution is, in burning need to be closed before some permanent memory program, such as closed CD automatic insertion notice, closed anti-virus software, Window task management and planning task procedures and screen saver, etc.
Common fault 6: cd-writing process, often can appear burn failure
Improve the success rate of burn need to keep system environment pure, namely close background resident program, best for burning system to prepare a special of the hard drive, special installation and burn relevant software. In the burning process, had better put the data stored in the first hard disk, made "ISO image files", and then burnt into CD. In order to guarantee burn process data transfer is fluent, need often to toshiba qosmio x305 series laptop cpu cooling fan hard disk fragments to arrange, avoid for file cannot be normal transmitted, burn caused by interruption error, can by implementing "disk scan program" and "a defragment program" to carry out the hard disk finishing. In addition, in the burning process, don't run the other programs, even the mouse and keyboard also do not go to easily to touch. Burn use computer had better not and other computer networking, and in the burning process, if the system administrator to the machine to send information, it will affect burn effect, in addition, in the local area network, do not use resources sharing, if in the burning process, other users read local hard disk, can cause burning work interrupt or failure. In addition, but also pay attention to the CD writer of the heat dissipation problems, good heat dissipation conditions will give CD writer a stable working environment, if because continuous burn, CD writer calorific value is exorbitant, can turn off the computer, such as lower temperature after continue to burn. For built-in CD writer best inside the case in add extra cooling fan. External burn confidential note dust, moistureproof, lest cause laser head, speaking, reading and writing is not normal.
Common fault 7: use EasyCDPro burn can't identify Chinese directory name
In the use of EasyCDPro burn Chinese filenames when,toshiba qosmio x505 series laptop cpu cooling fan can select the options in the file name Romeo, can support up to 128 a filename, namely 64 Chinese characters of the file name. In addition, WinonCD, Nero, DirectCD2. X and so on all can well support long Chinese filename, EasyCDCreator in this aspect to slightly some trouble.

What is memory dual channel
Dual channel memory technology is actually a kind of memory control and management technology, it depends on the chipset of memory controller work, in theory can make two the same specifications provided by memory bandwidth doubled. It has not any new technology, has been applied to the server and the workstation system, and just in order to solve the desktop increasingly distress memory bandwidth bottleneck problem it came to desktop motherboard technology front desk. In a few years ago, Intel company has launched a support toshiba satellite l505d-es5025 laptop cpu fan dual channel memory transmission technology i820 chipset, it and RDRAM memory constitute one pair of gold partner, played out and tribulations performance make it become the highlight of the market, but the production cost high flaws caused hurrah don't hit of the situation, was finally out by the market. Because of Intel has given in RDRAM has support, so at present the mainstream chipset double channel memory technology are refers to the dual channel DDR memory technology, mainstream dual channel memory platform Intel is Intel 910, 940, 945 series, and AMD aspects is NVIDIA Nforce2 series.
Dual channel memory technology is solve CPU bus bandwidth and memory bandwidth of the contradiction of low-priced, high performance scheme. Now CPU FSB (front end bus frequency) more and more high, Intel Pentium 4 than AMD Athlon XP to memory bandwidth is of much higher demand. Intel Pentium 4 processor and agp Data transmission using QDR (Quad Data Rate, four Data transmission) technology, the FSB is external clock 4 times. Intel Pentium 4 FSB respectively is 400, 533, 800 MHZ, bus bandwidth respectively is 3.2 GB/SEC, 4.2 GB/SEC and 6.4 GB/SEC, and DDR 266 / DDR 333 / DDR 400 can provide the memory bandwidth respectively is 2.1 GB/SEC, 2.7 GB/SEC and 3.2 GB/SEC. In the single channel memory mode, DDR memory cannot provide CPU need data bandwidth to become the performance of the system bottleneck.toshiba satellite l505d-es5024 laptop cpu fan While in double channel memory mode, double channel DDR 266, DDR 333, DDR 400 can provide the memory bandwidth respectively is 4.2 GB/SEC, 5.4 GB/SEC and 6.4 GB/SEC, here can see, double channel DDR 400 memory just can satisfy the 800 MHZ FSB Pentium 4 processor bandwidth demand. But to AMD Athlon XP platform is concerned, the processor and agp Data transmission technology USES DDR (Double Data Rate, Double Data transmission) technology, the frequency of the FSB is 2 times, its memory bandwidth demand far less than Intel Pentium 4 platform, the FSB is respectively 266, 333, 400 MHZ, bus bandwidth respectively is 2.1 GB/SEC, 2.7 GB/SEC and 3.2 GB/SEC, the use of single channel DDR 266, DDR 333, DDR 400 can meet its bandwidth demand, so in AMD K7 platform use dual channel DDR memory technology, convergence is not much, performance to improve is not such as Intel platform so obvious, the most obvious influence on the performance of or using integrated display chip integrated motherboard.
NVIDIA launched nForce chipset is the first person to turn the DDR memory interface expanded to 128 - bit chipset, then Intel in its E7500 server motherboard chipset also use the double channel DDR memory technology, SiS and VIA also in response, and actively developing this can make the DDR memory bandwidth has doubled since the technology. However, due to various reasons, in order to realize the dual channel DDR (128 bit parallel memory interface) transmission for many chipset makers is no easy task. DDR SDRAM memory and RDRAM memory completely different, the latter has the characteristics of high delay and for toshiba satellite l505d-109 laptop cpu fan serial transmission mode, these characteristics decide the design one support dual channel RDRAM memory chipset and difficulty of the cost is not too high. But DDR SDRAM memory but has its limitations, it itself is low delay characteristic, USES is the parallel transmission mode, and the most important thing: when the DDR SDRAM work frequency higher than 400 MHZ, the signal waveform will often appear distortion problem, all of these design one support dual channel DDR memory system chipset brings a lot of difficulty, chipset manufacturing cost will also improve accordingly, these factors are restricting the memory control technology development.
Ordinary single channel memory system has a 64 - bit memory controller, and double channel memory system have two 64 - bit memory controller, in double channel mode has 128 bit memory a wide, which in theory the memory bandwidth doubled. Although double 64 memory system provided by the bandwidth is equal to a 128 - bit memory system provided by the bandwidth, but both have effect is different. Dual channel system contains two independent, have complementary intelligent memory controller, theoretically speaking, two memory controller can in each other zero delay under the conditions of operation at the same time. For instance two memory controller, A for A, another for B. When controller B toshiba satellite l505-138 laptop cpu fan ready for the next access memory, the controller is A read/write main memory, and vice versa. Two memory controller such complementary "nature" can let the waiting time reduced by 50%. Dual channel DDR two memory controller on the function is exactly the same, and two controller timing parameters can be set separately programming. This flexibility allows a user to use two different structure, the capacity, the speed DIMM memory bank, the double channel DDR simply adjusting to a minimum memory standard to achieve 128 bit bandwidth, allowing different density/waiting time characteristics of the DIMM memory bank can reliably common operation.
Support dual channel DDR memory technology notebook chipset Intel platform have Intel 910, 915, 940, 945,, etc. Series.
Computer could support memory dual channel mainly depends on the toshiba satellite l505-11d laptop cpu fan mainboard chipset, support double channel chipset is described above, you can also view the mainboard chipset material. In addition some chipset in theory support different capacity of the memory bank realize double channel, but the actual or suggest use as far as possible parameter consistent two memory bank.
Memory double channel according to the general requirements on the mainboard memory slot color paired use, in addition some main board and in the BIOS do a Settings, general motherboard manual will have instructions. When the system has realized dual channel, some main board in the power on self test will there be prompt, can look at toshiba satellite l505-10j laptop cpu fan. Due to the self speed is faster, so can't see. So can use some software view, a lot of software can check, such as CPU - z, more compact. In the "memory" of a "channels" project, if here shows "Dual" such words, it means the has achieved double channel. Two 256 m memory constitute a dual channel the effect will be better than a 512 m memory effect is good, because a memory cannot constitute a dual channel.
