The so-called system does not recognize the mouse compaq presario c500 laptop keyboard, it is to point to power on self test, the system for "mouse did not detect" or screen shows "no installation mouse", but in fact is installed the mouse and its driver.
 
To make the mouse work, one is to hardware working properly, and the second is to load the correct driver, the third is to carry out the correct Settings. And the system does not have admitted the mouse fault by bad contact, mouse model setting error, mouse hardware failure, viruses or mainboard failure caused, generally follow the steps inspection and processing:
 
1. The first pull plug the mouse and host interface plug, check whether the contact is good, the treatment after restart your system.
 
2. If a fault is still exist, pulled out the mouse compaq presario cq60 100ea laptop keyboard interface plug, in a COM interface put up, and the CMOS of COM interface Settings make corresponding revision, restart the start.
 
3. If there is no problem solving, then check whether there is at the bottom of the mouse model set the switch, and if there is, try to change its position, restart your system. If there is no problem solving, is still the switch to the in situ.
 
4. If the fault is still exists, the use substitution method, a notice will be a normal of the same type of mouse and host connection, and then boot startup.
 
5. If the fault disappear, then explaining the mouse is a hardware failure cause, check the mouse compaq presario cq61 laptop keyboard interface plug and attachment without problems, such as no problems, then check the mouse X axis and Y axis movement organization or photoelectric receiving circuit system without problems.
 
6. If use substitution method after fault still exist, then explaining is soft failure. Exit Windows, in the DOS next check config.sys file or AUTOEXEC. BAT file is already joined the mouse driver; If not, then load mouse driver.
 
7. If in the DOS had already joined the MOUSE driver, again under Windows inspection SYSTEM. The INI file BOOT paragraph, whether or not to join the MOUSE. DRV = < filename > Settings item.
 
8. If the fault is still exists, the use KV300 testing antivirus, cold start again, check the mouse compaq presario v6500 laptop keyboard driver is in good condition, if any problem should be reinstalling. If the driver is good, then check the contents of the CMOS whether be modified, such as be modified should reset, then again boot startup.

Zero track in hard disk on a very important position,compaq mini 732et laptop keyboard hard disk master boot record (MBR) area in this position. MBR is located in hard disk 0 track 0 cylindrical 1 sector, including storage of a hard disk master boot program and hard disk partition table. In a total of 512 bytes of hard disk master boot record sector, 446 byte belongs to hard disk master boot program, 64 byte belongs to hard disk partition table (DPT), two bytes (55 aa) belong to partition end mark. Thus it can be seen, zero track once damaged, will make the hard disk master boot program and partition table information to suffer serious damage, leading to the hard disk can't boot.
 
Zero track damage belongs to one of the hard disk bad word, just because of its position is too important, so once destroyed, it will have serious consequences.
 
Usually the maintenance method is through the Pctools9.0 DE (disk editor) to repair (or similar to disk sector editing tools can also), the method is as follows:
 
With Windows9x startup disk boot, insert contains Pctools9.0 CDS. Operation of PCT90 compaq mini 733eb laptop keyboard directory DE. Exe, first enter the "Options" Tab menu, choose "Configuration" (Configuration) command, press "Spaces" key remove ReadOnly (read only) in front of the hook (according to the Tab key switch), later, save exit. Then Select and implement the main menu "Select" (choice) of the Drive (driver), in later in the "Drivetype" (Drive type) of paragraph, the choice of Physical (Physical), and press the blank space selected, and then click "Tab" key switch to "Drives" item, Select the "Harddisk" (hard disk), finally, Select "OK" and press enter.
 
Later, back to the main menu, open the "Select" menu, then will appear PartitionTable (partition table), selected and enter, then there are hard disk partition table information. If there are two hard disk partitions, l partition is disk C, this partition from hard disk 0 cylindrical start, then, will be 1 division of the BeginningCylinder from (cylindrical) of 0 to 1 is ok. Save then quit.
 
Note that in before modification will drive the important material backup out. Restart, according to the Delete button to enter back to the CMOS setup, choose "IDEAUTODETECT", we can see that CYLS number than the original reduced 1, after that, save Settings and exit. To partition, formatting, can save hard disk.
 
Note: because DE tool only to FAT16 partition hard effective,compaq mini 733ef laptop keyboard therefore, the FAT32 drive for the hard disk, it may through the partition master (PQ) disk tools, will FAR32 convert to FAT16, and then carry on the treatment.
 
In addition, there are some exploration out through the modified hard drive motor positioning system to change zero track position and through the circuit adjustment to change the distribution of the magnetic head logic, in order to achieve repositioning zero track purpose. Of course it needs more profound hardware level, the realization rise also more complex.
 
Partition table damage repair
 
Hard disk master boot record in the sector is also virus key attack place, through the destruction of the master boot sector DPT (partition table), can be easily damaged hard disk partition information. Partition table damage compaq mini 735eq laptop keyboard usually is not a physical damage, but partitioned data is destroyed. Therefore, usually, can use the software to repair.
 
Normally, hard disk partition after backup a partition table to floppy disk, CD or USB disk is very wise. This aspect, the domestic famous rising antivirus software provides a complete solution. In addition, for no backup partition table of the hard drive, also provides corresponding repair methods, but the success rate is relatively low.
 
In addition, Chinese disk tools DiskMan in this aspect is also great trouble-makers. Reconstruction partition table as one of its important function, very suitable for used to repair damaged partition table.
 
For the hard disk partition table was zoning adjustment software compaq mini 735es laptop keyboard(or virus) serious damage, cause the hard disk and system paralysis, DiskMan can not be destroyed by the partition boot record information to establish partition table. In the menu choose toolbar "rebuilding the partition table", DiskMan namely began to search and rebuild partition. DiskMan will be the first to search 0 cylinder 0 head from 2 sector began to the implicit sector, looking for virus moved the partition table. The next search each head first sector. Search process can use the "automatic" or "interactive" two kind of way. An automatic way to keep found each partition, it is suitable for most cases. Interactive way to find every division are giving prompt, selected by the user is retained. When an automatic way to reconstruction of partition table is not correct, can use interactive way to search.
 
But, you need to be aware that reconstruction partition table function cannot do one hundred percent of the repair partition table, unless you've backup a partition table, and then through the reduction before backup partition table to compaq presario a900 laptop keyboard repair damaged partition table. So visible, usually backup a partition table is so necessary!

Because hardware installation error, not compatible or hardware lenovo ideapad g465 laptop keyboard damage wait for a reason, it is apt to cause the hardware error, leading to the light is not work normally, heavy then system will not work fault. Encounter this kind of situation, once only through the POST self-checking of BIOS alarm warning tone, hardware substitution method or through the DEBUG card to find the cause of the problem. But these methods, use rise is not convenient, but also to the user's professional knowledge is also the demand is higher, for ordinary users do not apply.
 
To solve this problem, now the motherboard manufacturer to join a lot of humanized design, with convenient user fast and accurately judge the cause of the problem.
 
For example, now many motherboard special design the hardware and electric self-checking fault language broadcast function. With asustek "POST the reporter" as an example, the function mainly by winbond of W83791SD chip, with asustek design chip combination and become. Can monitoring CPU voltage, CPU fan speed, CPU temperature, lenovo ideapad g460 laptop keyboard casing fan speed, power supply fan is failure, chassis invasion of warning, etc. In this way, it is better to keep the computer the best working condition. When the system has a certain equipment trouble, POST the reporter can use voice remind the parts out of the fault.
 
In the team of the hardware fault alarm, some main board companies have their own very original design. Such as msi motherboard, with the four LED to reflect the malfunction of the motherboard. And some main board is simply introduced earlier Debug mapping team of the wrong CARDS wrong technology, using a more direct digital tube to indicate the malfunction.
 
In addition, many manufacturers for lenovo ideapad b470 laptop keyboard the mainboard design the AGP protection circuit, in addition to the graphics protection besides, protection circuit with a LED light-emitting diodes, to tell the user fault is caused by the graphics card.

Netbook what all good, not only convenient place is not drive (this is also a small notebook msi dfs451305m10t laptop cpu fan limitations), unlike traditional PC as a problem the system disk into drive in a plug, has been in the next step, 30 minutes can do easily calm. The Internet and the one thousand system collapse, do system is more troublesome.
 
A good friend MM anson R69 netbook last week serious virus intrusion, antivirus after the system has not been very smooth, so let me to give her a consultation. After three hours of research, I finally learned how to use usb flash disk do startup disk, and give netbook reinstall XP system method. I think this method than any other system installation method is simple a lot, so bring and the jar friends share.
 
Preparation: a U disk, WinPE tool software, Flashboot software, WindowsXP installation of the software system.
 
U disk startup disk production:
 
1, U disk formatting: Suggestions to prepare a 2 g capacity above the U disk (will copy XP system and U disk boot software,msi e32-0800110-mc2 laptop cpu fan so want to have enough space, and now U disk is very popular, I use is SONY Ericsson digital 4 g U disk), use first Flashboot (from online can download) will U disk formatted into USB - HDD or USB - ZIP one of these two kinds of modes. Anson R69 etc netbook basic support the two formats.
 
2, U disk version WinPE tools: downloaded from the Internet WinPE U disk version of the software to the U disk, I download on the net is more popular old wild peach WinPEU disk version, unzip the files are kao into formatting good U disk in the.
 
Windows XP system installation
 
1, set U disk boot, boot after long press F2 to enter the system boot sequence Settings,msi gb0506pdv1 laptop cpu fan in the menu select "USB boot" option, and make it from the "Disabled" into "Enabled", then netbook from U disk launched. With the traditional PC BIOS Settings are the same.
 
How to use usb flash disk to the Internet this install XP system?
 
2, XP system installation: before the prepared XP setup disk all kao into U disk, and then insert the usb flash disk and boot, directly into the U disk boot, then there will be a boot menu, choose start on the menu in miniature WIN - PE, they entered the WinPE system. Will XP SETUP disk from U disk kao into of the display system disk (C) outside of the partition, such as D plate or E disk, and then direct operation XP system installation folder SETUP. EXE file, it appeared we are very familiar with the XP installation interface, according to the XP system installation prompt step by step the complete.
 
In addition to using usb flash disk installed outside,msi wind-u100 laptop cpu fan now anson R69 etc netbook provide "a key recovery" function in the event system problem, also can use this a simple function is easily solve the system restore problem. Of course, if you want to be a new installation system, recommended me to introduce U dish of method of installation.

Message personage points out, the Haswell Intel processor of the sony vaio vgn-n130p laptop keyboard third generation Ultrabook may not all adopt the wireless charging technology, is expected to only a few a few models will carry this function.

Tualatin
This is the well-known "figure Latin" the core, is Intel Socket 370 architecture in the last kind of CPU core, use 0.13 um manufacturing process, packaging mode using FC - PGA2 and PPGA, core voltage also reduce to 1.5 V or so, basic frequency range from 1 to 1.4 GHz GHz, external clock respectively for 100 MHZ (cy young) and 133 MHZ (Pentium III), level 2 cache respectively for 512 KB (Pentium III - S) and 256 KB (Pentium III and cy young), this is the strongest Socket 370 core, its performance and even more than the early low-frequency Pentium 4 series of CPU toshiba satellite a85 series laptop cpu cooling fan.
 
Willamette
This is the early Pentium 4 and P4 cy young using core, the original Socket 423 interface, and then convert Socket 478 interface (cy young only 1.7 GHz and 1.8 GHz two kinds, are Socket 478 interface), use 0.18 um manufacturing process, front-end bus frequency for 400 MHZ, basic frequency range from 1.3 GHz to 2.0 GHz (Socket 423) and 1.6 GHz to 2.0 GHz (Socket 478), level 2 cache respectively for 256 KB toshiba satellite a85 s107 laptop cpu cooling fan(Pentium 4) and 128 KB (cy young), note, and some types of Socket 423 interface Pentium 4 didn't level 2 cache! Core voltage of 1.75 V or so, encapsulation using Socket 423 PPGA INT2, PPGA INT3, OOI 423 - pin, PPGA FC - PGA2 and Socket 478 PPGA FC - PGA2 cy young and the PPGA, etc. Willamette core manufacturing technology is backward, calorific value, the lower performance and has been eliminated, and replaced by Northwood core.
 
Northwood
This is the mainstream of the Pentium 4 and cy young the core, its and Willamette core biggest improvement is made by 0.13 um manufacturing process, and use Socket 478 interface, core voltage of 1.5 V or so, level 2 cache respectively for 128 KB (cy young) and 512 KB (Pentium 4), front end bus frequency were 400/533/800 MHZ (cy young are only 400 MHZ), basic frequency range were 2.0 GHz toshiba satellite a85 s1072 laptop cpu cooling fan to 2.8 GHz (cy young), 1.6 GHz to 2.6 GHz (400 MHZ FSB Pentium 4), 2.26 GHz to 3.06 GHz (533 MHZ FSB Pentium 4) and 2.4 GHz to 3.4 GHz (800 MHZ FSB Pentium 4), and 3.06 GHz Pentium 4 and all 800 MHZ Pentium 4 support hyper-threading Technology (Hyper - Threading Technology), encapsulation using PPGA FC - PGA2 and PPGA. Intel in accordance with the planning, Northwood core will soon be replaced Prescott core.
 
Prescott
This is the high-end Pentium 4 EE, mainstream Pentium 4 and low amdk6 series D the core. Prescott core and Northwood core the biggest difference is that USES 90 nm manufacturing process, L1 data cache from 8 KB increase to 16 KB, pipeline structure also from 20 level increased to 31st level, and began to support SSE3. Prescott core CPU initial use Socket 478 interface, now basically has all turned to Socket 775 interface, core voltage of 1.25-1.525 V. Front end bus frequency, Celeron D all 533 MHZ FSB, and besides Celeron D other than the CPU for 533 MHZ (does not support hyper-threading technology) and 800 MHZ (support hyper-threading technology) and the highest 1066 MHZ toshiba satellite c630 series laptop cpu cooling fan(support hyper-threading technology). Level 2 cache respectively for 256 KB (Celeron D), 1 MB (Socket 478 interface pentium 4 and Socket 775 interface pentium 4 5 xx series) and 2 MB (pentium 4 6 xx series and pentium 4 EE). The encapsulation PPGA (Socket 478) and PLGA (Socket 775). Prescott core since since the launch is also in constant improvement and development, has joined the hardware anti-virus Technology Execute Disable Bit (EDB), energy saving save electricity Technology Enhanced Intel SpeedStep Technology (EIST), Virtualization Technology Intel Virtualization Technology (Intel VT) and 64 Technology EM64T, etc., level 2 cache also from the initial 1 MB increased to 2 MB. Intel in accordance with the planning, Prescott core will be Cedar Mill core replaced.
 
Smithfield
This is the first paragraph Intel company dual core processor core type, basically can think Smithfield core is a simple two Prescott core loose coupling together of the product, which is based on the independence of the cache loose coupling scheme, its advantage is technology is simple, defect is performance is not ideal, at present the Pentium D 8 xx series and Pentium EE 8 xx series adopt the core. About Smithfield detailed information can view Intel dual core type
 
Cedar Mill
This is the Pentium 4 6 x1 series and Celeron D 3 x2/3 x6 series using core, from 2005 began to appear at the end. Its and Prescott core the biggest difference is that USES 65 nm manufacturing technology, and other aspects of the change is not big, basically can be considered a Prescott core 65 nm process version. Cedar Mill core all adopt Socket 775 interface, core voltage of 1.3 V or so toshiba satellite c640 series laptop cpu cooling fan, encapsulation using PLGA. Among them, the Pentium 4 all for 800 MHZ FSB, 2 MB level 2 cache, support hyper-threading technology, hardware anti-virus technology EDB, energy-saving province electric technology EIST and 64 technology EM64T; And Celeron D is 533 MHZ FSB, 512 KB level 2 cache, support hardware anti-virus technology EDB and 64 technology EM64T, does not support hyper-threading technology and energy-saving province electric technology EIST. Cedar Mill Core is Intel processor NetBurst architecture in the last paragraph single Core processor Core type, according to the Intel planning, Cedar Mill Core will gradually be Core framework Conroe replaced the Core.
 
Presler
This is the Pentium D 9 xx and Pentium EE 9 xx using core, also is introduced by the end of 2005. Basically can think Presler core is a simple two Cedar Mill core loose coupling together product, is based on the independence of the cache loose coupling scheme, its advantage is technology is simple, defect is performance is not ideal.
 
Yonah
At present the Yonah Core CPU has double Core Core Duo and single Core Core Solo toshiba satellite m100 laptop cpu cooling fan , another Celeron M also USES this Core, Yonah Intel is launched in early 2006. This is a kind of single/double core processor core type, its application features a very big flexibility, can be used in desktop platform, can also be used to mobile platform; Can be used in dual core, also can be used for single core. Yonah core from the mobile platform big-name processor Pentium M outstanding architecture, with line series less, implement high efficiency, strong function and low power consumption etc advantages. Yonah core adopts 65 nm manufacturing technology, interface type is improved new Socket 478 interface (and desktop before the Socket 478 is not compatible). Yonah core support hardware anti-virus technology EDB and save energy EIST electrical technology, but its biggest regret is not support 64 technology, just 32-bit processor. It is worth noting that the Core Duo Yonah Core is adopted two Core sharing 2 MB level 2 cache. Shared secondary cache with Intel's "Smart cache" Shared buffer technology to realize the true sense of the cache data synchronization, reduced the data delay, and reduced the rate of front end bus take up. Yonah core is Shared buffer close coupling scheme, its advantage is performance ideal, defect is technology is more complex.
