1, look for the male plate design
Front said, some motherboard manufacturer for toshiba satellite l600d-09b laptop cpu fan
saving cost, lower the price, not only will the mainboard volume change little, also do not use male plate design, even in the motherboard materials on the corresponding adjustment, only satisfies chipset proposed basic performance requirements. The lower the cost of practice is to the manufacturer's main board layout design ability of a test: in a small space placed the same expansion slots, and maintain stability and limit electromagnetic interference, so that the rationality of the design of main board structure arrangement is especially important, a bit of a design is not reasonable will lead to crash.
From this point of view, the strength of the manufacturers can easily be in these places appear loophole, motherboard instability, poor performance are caused by. So, for consumers, if there is no special requirements, or choose the male plate design of the motherboard is better.
How to identify motherboard toshiba satellite l600d-63b laptop cpu fan
is male plate design, that is about to see users to chipset mastering of the. For example a most chipset provide 6 PCI interface, but the user to the purchase of motherboard while using this chipset, but only provides four PCI interface, this is the non-state-owned plate design. In fact, in the motherboard manufacturer in the world rarely completely according to male plate design.
2, observe the CPU socket position
CPU socket position is very important. If on the mainboard is too close to the edge, then in some the space is narrow or power position not reasonable inside the case will be installed CPU radiator difficult situation (especially in the user want to change radiator and don't want to make the whole motherboards and out). By the same token, the CPU toshiba satellite l630-01s laptop cpu fan
socket around the electrolytic capacitor should not get too close, otherwise one is not convenient installation radiator (and even some CPU large radiator simply can't install); for another, may damage the electrolytic capacitor.
3, observe the ATX power supply position
Almost every motherboard ATX power supply interface position is different. Reasonable position should be on the mainboard edge on one side of the right or the CPU socket and memory slot between, and should not appear in the CPU toshiba satellite l630-02s laptop cpu fan
socket and left between I/O interface. This can avoid some power supply connection too short awkward, also won't appear in CPU radiator installation or influence CPU surrounding air circulation problems.
4, observe the memory slot position
Attention should be paid to the installation longer AGP display card, and graphics card adjacent memory slot buckles will can't open. If it is in memory and must take graphics down, that you will be in trouble. In addition, the memory slot also should not be too close to the right edge main board, or else it may lead to installation cd-rom drive and memory bank when collision.
5, observe the floppy drive and IDE equipment interface position
Floppy drive and IDE interface position, if in the main board by the right, need to consider whether the cd-rom will be the; If the main board on the toshiba satellite l640-00u laptop cpu fan
right, it should not only consider the will to installation longer PCI interface card, also want to consider if the case is bigger, may appear IDE data line not enough long situation.
Thus it can be seen, main board structure layout problems not only may affect the stability, sometimes some details will also lead to consumers use not convenient. Strong motherboard manufacturer tend to fully consider the user convenience, for example some large capacitance shoulds not be placed in PCI slot, AGP slot near, because they have may hinder part of the expansion card insertion. And as now CPU radiator volume is more and more big, this will request the CPU socket nearby large capacity electrolytic capacitor can't from socket too close, should give huge CPU toshiba satellite l640-02v laptop cpu fan
radiator reserve enough space. But at the same time, in order to improve power quality, in order to the stability of the CPU, and must be placed in the CUP plug near a large number of electrolytic capacitor. For some big manufacturer is concerned, they can be both treatment is very good, if it is a small factory of words, may not know what to do.

Graphics common troubleshooting
Common fault one: show no boot
Such fault general because graphics and motherboard bad contact or motherboard toshiba satellite a10 sp129 laptop cpu cooling fan slot have caused problems. For some integrated graphics motherboard, if memory Shared main memory, it is required to pay attention to the position of the memory bank, generally in the first memory bank slot should be inserted in a memory bank. Due to the graphics cause boot show no fault, after startup generally will be issued a long two short bumming (for AWARD BIOS for video card).
Common fault 2: display flowers screen, see not clear handwriting
This kind of failure is usually due to a display or video card does not support high resolution and cause of. Flowers screen can switch startup mode to the safe mode, and then in the Windows 98 to enter the display Settings, 16 color state click on the "application", "ok" button. Restart, Windows 98 system normal mode delete graphics driver program, and then restart the computer toshiba satellite a15 s127 laptop cpu cooling fan. Also don't enter the safe mode, in pure DOS (henan emba) environment, editing SYSTEM. The INI file, will display. DRV = pnpdrver to display. DRV = VGA. DRV, save exit, and then in the Windows update driver.
Common fault 3: color display is not normal, this kind of failure usually have the following reasons:
1. The graphics card and display signal wire bad contact
2. Display their own fault
3. In some software running in the color is not normal, general common in old machine, in the BIOS has a school
Check the color options, its open can
4. Graphics damage;
5. Display was magnetization, this kind of phenomenon is toshiba satellite a15 s129 laptop cpu cooling fan generally with magnetic objects can too close to be caused by, magnetic change after may cause show scenes appear deflection phenomenon.
Common fault 4: system halted
Such fault appears more commonly found in main board and the graphics card not compatible or motherboard and graphics bad contact; graphics
And other expansion card not compatible can also cause system halted.
Common fault five: screen abnormal noise point or design
This kind of failure is usually due to the graphics memory problems or graphics and motherboard bad contact cause. Need to clear clean graphics goldfinger site or replace graphics.
Common fault 6: graphics driver program lost
Video card driver loaded, running after a period of time the toshiba satellite a15 s1292 laptop cpu cooling fan drivers are automatically lost, this kind of fault is generally in graphics by poor quality or graphics and motherboard not compatible, make graphics temperature is too high, resulting in system operation instability or appear crash, the only change video card.
In addition, there is a kind of special circumstances, before can be loaded with graphics driver program, but in graphics driver program load into, into the Windows there was a crash. Replaceable other types of graphics in load the driver, insert the old graphics resolved. If it can't solve the fault, then explaining the registry fault, to the registry in henan from toshiba satellite a15 s157 laptop cpu cooling fan an line recovery or reinstall the operating system can.

Computer panel plug and motherboard socket qiao pairing
A computer host for dust removal will unload mainboard,toshiba satellite l30-105 laptop cpu fan reshipment is found that chassis panel power supply reset switch, hard disk power light and horn and two USB terminal plug, because no mark. The plug can't recover and cannot use.
Then, using the panel on the device function characteristics, had the order one try plug. Considering on the mainboard joint panel plug seat needle group, generally only with low pressure low current (USB needle group except), therefore bold a try.
First, you have to find the plug of the power switch position, the method is to supply power on, and then hold panel on the power switch don't put, will switch the plug of the plug one here in the needle. When inserted into a two support after needle of switch power supply fan start, explain the power switch A computer host for dust removal will unload mainboard,toshiba satellite l20-sp231 laptop cpu fan reshipment is found that chassis panel power supply reset switch, hard disk power light and horn and two USB terminal plug, because no mark. The plug can't recover and cannot use.
Then, using the panel on the device function toshiba satellite l30-101 laptop cpu fan characteristics, had the order one try plug. Considering on the mainboard joint panel plug seat needle group, generally only with low pressure low current (USB needle group except), therefore bold a try.
First, you have to find the plug of the power switch position, the method is to supply power on, and then hold panel on the power switch don't put, will switch the plug of the plug one here in the needle. When inserted into a two support after needle of switch power supply fan start, explain the power switch seat needle may find right. Note: if the plug in a needle inserted into other ground needle, so power while also can start, but the toshiba satellite l20-s310td laptop cpu fan rest of the one or more plug will find no correct position. If appear this case, you will switch plug a pinhole inserted into the adjacent needle can. Start computer and then find the power indicator of a needle. Because light emitting diode is polar components (hard disk lamp), if the plug after reaction can not bright, so should be positive and negative try plug. If the hard disk read time, such as inserted into a two needle is flashing light, this group of needle may be hard disk lamp seat needle, then can will be hard disk light seating. If the brightness of the light is light or dark, this kind of circumstance are considered not check the number, should continue to search.
The next get reset switch seat needle position, will reset switch hold not to put, will plug the switch to the rest of the needle position, if the system appear reset. This group is reset switch position. The rest of the horn plug, using computer alarm sound characteristics is very easy to find the location of the should be inserted. In principle, horn also points are negative, but chassis little horn regardless of also just as well. Due to the USB terminal plug into two four core plug. Two groups of joint of shielded wire inserted a is negative. On the mainboard USB a needle for a list of eight needle, assuming that head needle or tail needle for the first stitch, using a multimeter to measure 1 needle and toshiba satellite l20-c430 laptop cpu fan eight needle is + 5 v (voltage to ground), 4 needle and five needle for negative (resistance to earth). This shows that plug 1 hole is + 5 v a, 2, 3 hole for data bits, 4 hole for negative patients (shielding layer), another group, too, so two plug respectively were para insert. Then try USB terminal had better use MP4 try, because the USB MP4 power supply loop string a diode. If power joint was also won't damage. The above method is forced to do so and, perhaps is fluky without a problem.
