IBMT61 laptop and battery Fn + F7 the ultimate solution to the problem failure

IBMT61 laptop and battery Fn + F7 the ultimate solution to the problem failure

Poor T61P fast hand half, the system just installed a good, all is that Fn + F7 to make trouble! Recovery Disk Presario 2500(compaq 2500 battery) are downloaded in preparation for tonight and then Gao Buding Recovery Disk on the filling, it is after all scared!


Tried the new version, old driver, tried to upgrade using SU-line, and TVT-driven software, and even tried a new old driver hybridization, no fruit, bruised and battered!


IBM OEM XP SP2-line to upgrade all patches, all the drivers and TVT manually install the latest version of the software used (SU Tai Lan, IS seems to able to use the safe side, the most reliable manual), including the Hotkey and Presentation Director is the Presario NX9010 latest version.


XP SP2 and drive when you have just installed everything OK, long accustomed to the upgrade process of disabling a number of system services, system upgrade is complete, restart, Fn + F7 Failure!


Repeatedly to configure system services and eventually found that if Terminal Services is disabled, Fn + F2, Fn + F3, Fn + F7, Fn + F8, Fn + F9 will all fail, only the volume, screen brightness, Fn + F5, Fn + F4, Fn + F12 is available!


Terminal Services will be set to manual or automatic, Fn full function was normal! Even if set to manual, boot will be loaded automatically. Hotkey Presario NX9000 support for earlier versions do not need this service


Terminal Services according to the literal interpretation, how not implicated in the Hotkey on the relationship with, and this service can not be stopped once started, strange!


BTW: frustrating process, with the PE + ghost8.0 backup and restore a system, that operation is correct, restore, the boot files NTDETECT.COM, ntldr went to D and E disk to disk, and the rest of the system files are in the C disk, Little did I think about it, readily deleted, but also forgot to look at C drive there are no two documents, the results can not start, speculated that it was not a backup and restore are mainly as the SATA AHCI mode, PE + ghost8 problems? Like PE + PQ8 partition in SATA AHCI mode, there are problems.

Because they could not start, but that seemed to have a partition F2299A problem, reinstall the system again tonight, discovered that Terminal Services problems.

This is the X60 completed on, T61P or the bare system, no way to shots, if needed on the map and then on another day (as if the plan does not require it?) Since the problem is resolved, driver version do not bother to investigate the

On the notebook drive and batteryto use some of the considerations

On the notebook drive and batteryto use some of the considerations

notebook and battery drive is a very precious component, coupled with the high frequency of use, life is indeed Laptop Battery very limited. Therefore, many business-to-drive components of the warranty time is far shorter than the other parts. In fact, affect the life of the main drive is the laser head, laser head is actually the life of drive life. To extend the drive life, it should start batteryfrom the laser head of maintenance, specifically the following 10 law:


First, to keep CD-ROM, CD-ROM cleaning


CD-ROM uses a very precise optical components, and optical components are most afraid of is the dust pollution. The dust from the CD-ROM into, out of the whole process, the cleanliness of the CD-ROM disc is also directly related to the life. Therefore, the CD-ROM in the drive before loading the necessary cleaning of the CD-ROM does not use proper care to prevent dust pollution.


 


Second, regular cleaning and maintenance of laser head


CD-ROM used for a period 4834T of time, the laser head is bound to infected dust, so that a reduced ability to read the disk drive. Concrete expression to slow down to read the disk, display pictures and sound in mosaic or pauses, and in severe cases can be heard frequently drive to read CD-ROM's voice. Of these phenomena on the laser head and drive battery motor and other components are damaged. Therefore, the user should be cleaned regularly drive maintenance or for a professional maintenance.


 


Third, to maintain the horizontal drive


In the machine using the process, the drive to maintain the level place. The reason is that the disc is in rotation due to imbalance in the center of gravity changes, a slight decline in the ability to read the disk when you can, in severe cases can damage laser head. Some people use a computer CD-ROM in a different machine to install software, and often removed the drive brought take that, or even carry, which is F4098A very damaging to the CD-ROM. , The harm is within the CD-ROM optical components, laser head due to vibration and tilt changes in place, resulting in optical performance.


 


4, to develop a set off the habit of taking time before the


Once inside the CD-ROM drive, not only battery when the computer starts to read the disk to have a very long time, and has been in a CD-ROM will also be high-speed rotation state. In this way, an increase of the laser head of the working hours, also within the drive motor and transmission components in a worn state, virtually shorten drive life. Recommend that users want to develop a good time before the shutdown remove from the CD-ROM CD-ROM habits.


 


5, reducing the working hours of CD-ROM


In order to reduce the use of F4809A drive time to extend its life, the use of the computer users in the case of hard drive space allows, you can put frequently used discs made of a virtual CD-ROM stored on your hard disk. Such as educational software, games, software, etc. stored in the hard disk, so that later can be run directly on the hard disk, and have battery fast speed.


 


6, with less use of pirated optical discs, CD-ROM multi-purpose genuine


Many of my friends because of the price of pirated optical discs with a certain gap between the price of genuine CDs, plus CD-ROM is rich in content to buy to use, based on China's national conditions, this is beyond reproach, but because of your long-term reading of pirated optical discs, because of its poor quality disc , the laser head need to repeatedly read the data. This increase in motor and laser heads working hours, thus greatly reducing the service life of drive. Currently the price of genuine software has been greatly decreased, and some only slightly more expensive than the pirated F4812A software, and CD-ROM drive access assured. It is proposed that we minimize the use of pirated optical discs in the future more battery than the use of legitimate discs.


 


7, the correct opening and closing plate box


Either way, drive, front panel has a box and closed box button, use this button switches of conventional CD-ROM disk box right approach. Button when the finger can not be too much force to prevent the keys out of control. Some users used their hands to push back the direct disc box, which drives the drive gear is a kind of damage, it is recommended the user to overcome this bad habit.


 


8, using procedures of opening and closing plate box


The use of procedures 319411-001 switchboard boxes, and in many multi-media player software or tools have this function. If the windows using the battery mouse right-click the CD-ROM drive letter, its pop-up menu also has a "pop-up" command, you can eject the disc box. Users are advised to make full use of software-controlled opening and closing disc box, this would reduce the incidence of drive failure.


9, careful maintenance of


As the CD-ROM of all the parts are very sophisticated, users open the drive and installation process must pay attention to ways and means, pay attention to records of the original fixed position. If you are not sure if the professional maintenance personnel could be invited to disassembly and maintenance. In particular the aging of laser head, need to adjust the drive power to increase the power of laser tube, be sure to ask the professional maintenance staff debugging, to prevent their own adjustments too large, making laser head burned.


10, as little as possible DVD release


This avoids drive to work long hours due to a long continuous drive read the disk, a battery great impact on the drive life. Users will need to regularly Presario 2100(compaq 2100) laptop battery broadcast programs, better be copyed into the hard disk to ensure that the drive longevity. If you do often depends on DVD, it is recommended to buy a cheap low-speed drive designed to play vcd.


A better understanding of notebook memory and battery

A better understanding of notebook memory and battery

Significance of notebook memory and battery

With the operating system and application software bigger and bigger, the requirements also become increasingly harsh operating Laptop Battery environment, a number of large-scale applications, the minimum required memory should be 128MB, the memory below this requirement, the machine will not be allowed to install the software. As notebook computers scalability is not strong, not many can be part of the upgrade, only the memory, hard drives, CD-ROM of these. The drive to further improve its speed is not the case of upgrading the performance improvement is not. In this way, upgrading the memory to improve notebook performance becomes an important way.

Memory Classification


1, EDO memory, notebook memory and battery can be divided into EDO, SDRAM, DDR 3 kinds. On the EDO is now difficult to see. This memory is mainly used for the old MMX and 486 models above, there are some manufacturers (eg Dell) in the PII notebook computers still using EDO memory EDO single maximum capacity of this is only 64M, and because the working voltage of EDO memory 5V, and now commonly used in SDRAM's 3.3V power is more costly than some, it was quickly replaced by the next SDRAM memory.


2, SDRAM memory, a Pentium INSPIRON 2650 laptop through the era, CPU speed has been faster and faster, if the memory speed is not immediately follow suit, then the efficiency of the entire system will be seriously affected, when Intel filed a landmark memory technology ---- SDRAM. SDRAM stands for Synchronous Dynamic Random Access Memory (Synchronous Dynamic then memory), as its name suggests, this RAM can make all the input and output signals remain synchronized with the system clock. As the bandwidth of SDRAM for 64Bit, so it only needs a memory, you can work, data transfer speeds faster than EDO memory of at least 25%. SDRAM, including PC66, PC100, PC133 and other specification. PC66 already out of the stage of history, and now active in the notebook of SDRAM memory PC100 and PC133, PC100 and from the beginning, memory, joined the SPD chip. He called SPD chip? SPD is the English abbreviation of Serial Presence Detect, which refers to memory on a smaller than normal SDRAM IC and its E2PROM devices inside the recorded data; SPD which the data have 128Byte, each one represents a specific meaning, respectively, noted that the memory of a variety of information, including capacity, composition, performance parameters and manufacturer information. Suggest that you choose to purchase SPD chip is located in the middle of memory. Why? Because the majority of notebook computers in the vicinity of the memory slot motherboard 1G222 design are very compact, when the memory needed to install SPD chip down when the SPD chip is located on the side of the memory slots may be blocking the border could not be installed. As technology advances, which led to PC133 memory, which is now the most common notebook memory and battery, the price is relatively cheap and the performance is not weak. Some people might be such a mistaken view that the PC133 definitely faster than PC100, Oh, No, not if the word:). We know that when the memory read operation, its time for the completion of a read operation TCL + TRCD + TRP +1 clock cycles, therefore, to read the memory directly affects its speed, as in (BL = 1) of the cases, it is PC100 faster than PC133, but in other modes (for example, BL = 48) is the PC133 fast.


3, DDR memory, laptop memory, desktop computers are always followed the footsteps of the progress of memory. With the 2000 launch of DDR memory, after a very long period of time laptops have also entered the DDR era, although the desktop market, there is no doubt that DDR is the most self-cultivation of memory, have occupied 70% of the market share. But in the notebook field, it is a new type of technology, DDR is only PC2100 (or DDR266) a kind of BAT3151L8 specification, now in the mainstream adoption of Pentium4-M, Pentium-M, P4-core Celeron machines are based on DDR memory, but also a small amount of The Pentium3-M into the DDR machines early age:) In fact, the principle of DDR is not complicated, it allows a pulse to read the original first data in a SDRAM read both times within the pulse of information, that is, the pulse rising edge and the decline in the use of geo-channel funny, so the DDR is essentially SDRAM. As the name suggests: Double Data Rate (double data transfer). And relative to the EDO and SDRAM, DDR memory, more energy-efficient (working voltage of only 2.25V), a single greater and greater capacity (which has up to 1GB).

Memory characteristics

1, notebook memory and battery compatibility reference memory, it can not but mention the compatibility issues. Notebook computers are well known to the memory of the critical things, they would often not compatible and can not identify the laptop or cause instability, particularly in the early notebook memory and battery is often customized by the manufacturer, different manufacturers of memory simply is not compatible, it is necessary very difficult to buy. As in recent years, there has been a few relatively large memory manufacturers, such as KingSton, KingMax and so on, they began a big notebook manufacturers for OEM notebook memory and battery, but by itself produce its own brand of memory. Slowly, notebook memory and battery compatibility issues have been better:), but still there is a notebook memory and battery Latitude X300 compatibility issues, it is because the notebook memory and battery slots there are in fact relatively small differences, choose the best notebook memory and battery, based on three Benchmark: Select a width of 30mm of memory. Select SPD center of the memory. Choose exclusion of memory. More than 1,2 points from the physical conditions have a strong notebook memory and battery compatibility, point 3 is in line with PC100, PC133 standard external conditions.

2, notebook memory and battery, power consumption of a number of friends often ask to replace a large-capacity notebook memory and battery, will not reduce the notebook standby time? The answer is yes. As the memory operating voltage, capacity, different, replacing the large-capacity memory, more or less will reduce the notebook standby time, but tests show that the result is not very obvious, is generally shorter 10-15 minutes. Well, in order to reduce power consumption, we try to use less silicon chip surface area of a large memory modules: the same one-chip power consumption is the same, so the memory chip work with less power consumption low; chip area of the General Assembly, scattered heat faster. That is why we promote the use of large capacity single-chip memory that fewer why.


3, notebook memory and W0465 battery, notebook computers due to expansion of the memory slots are extremely limited, in the P2 is basically no age may escalate to a P3-M era, a notebook can be expanded by adding a red slot (motherboard integrates a memory, but also said the on-board memory). But now, using a P4-M notebook processor, basically provides two memory slots available to upgrade (but now there are some models, such as IBM's X30 and so canceled the design of onboard memory, this design is more used by manufacturers, giving customers greater choice, memory slot up two to a maximum upgrade to 1G memory). Do not know if you noticed No, notebook memory and battery slots are put together side by side, or a slot at the bottom of the notebook; the other on the keyboard below the symmetry with each other. Why is this? Actually, it is quite simple. This is because the memory chip lines to the distance between groups should be the same, so as to avoid two direct memory exist "jet lag" and the destabilizing factors


Installation and use of the Attention


1, we have to install the memory when the laptop should be noted that different types of memory can not be inserted chaos, if accidentally put 3.3v into the SDRAM Inspiron 2000 memory 5V, EDO memory slot, due to the different interface voltage will be a direct result of RAM burning. To prevent this from occurring now, from the DDR start, manufacturers of memory in these two gaps in the design deliberately misplaced. This is also the distinction between DDR memory and SDRAM memory, one of the easiest ways.


2, desktop memory installed for the average users, not a problem, but the notebook computer memory expansion of the layers as the mysterious veil of Mongolia, allowing users to some overcautious. In fact, the user only has to follow certain rules coupled with bold but cautious can be successfully completed. Laptop memory card form factor has, socket type and three kinds of style. Card memory expansion card when you pay attention to needle-arranged manner as slot-arranged manner must be consistent, do not plug into the expansion port on the modem, so at worst, could not get into the heavy pins are damaged. Socket memory expansion Note that even when forced under the pressure Latitude LS alignment interface.

The battery self-discharge causes

The battery self-discharge causes

1, lead-acid batteries:


1. Lead dioxide electrode self-discharge


(1). Oxygen evolution caused by Inspiron 1000 self-discharge (2). And alloy plate contact corrosion, lead dioxide is reduced to form aluminum sulfate ... (3). With oxygen role (4). And impurity effect.


2. Lead electrode self-discharge of


Lead electrode self-discharge from the hydrogen and oxygen corrosion, but because the solubility of oxygen in sulfuric acid is small, and can be removed.


Electrolyte solution in the hydrogen ion concentration of the high hydrogen evolution caused by apparent self-discharge. Equilibrium electrode potential of lead than the balance of hydrogen negative electrode, but due to lead in the high overpotential Inspiron 2200 of hydrogen evolution, hydrogen evolution reflects not obvious. If you lead the higher purity and impurity less hydrogen corrosion of the more light, lead electrode for hydrogen evolution due to the smaller self-discharge.


2, nickel-cadmium batteries self-discharge performance


Sufficient electricity for the nickel oxide electrode, due to instability of the manganese dioxide, stored in the process prone to oxygen evolution reaction, resulting in self-discharge. Cadmium anode in the electrolyte solution is very stable, so nickel-cadmium batteries self-discharge rate of the smaller, but the high-rate discharge of the nickel-cadmium batteries, due to a larger electrode 312-0292 surface area, so a larger self-discharge rate.


3, Ni-MH battery self-discharge characteristics of


Like other batteries, nickel-metal hydride batteries are also a certain degree of self-discharge phenomenon. High-voltage nickel-metal hydride battery device is the battery shell filled with hydrogen, the negative electrode active material of hydrogen and electric power active material nickel oxide cathode in INSPIRON 2600 direct contact, on the deferment to reflect self-discharge occurred during the
