Some Parameters for Computer Accessories

Posted on May 11, 2012 by Yedda

Most of these parameters are in the memory factory by the manufacturer based on the memory model species set out, for example, PC2100 of DDR PC800 RAMBUS PC133 the SDR, Sony Vaio computer batteries will give them to set different parameters. We can not own random changes to it.

Calibration memory and buffer memory, and we introduce memory there is not the same place. For the synchronous memory clock frequency (which in some special circumstances particularly demanding) the data before output is first placed in a storage module that is called the “parity zone”, so a lot of people have this memory is called”Checksum memory. This ensures that all data is read out from memory the “Sync”, so you can avoid a lot of data read and write errors. Such a validation process will consume a clock cycle, so theoretically CAS parity memory will be 2 and CAS 3 unbuffered memory performance – do not hold anything against that, all this is to the stability of the data.

Perhaps some of my friends will notice, when the memory set to CAS 2 mode, but the performance of the system also the default CAS 2.5 / 3, which is what causes it? My understanding is this: the memory simply can not work in that mode, the user forced the memory settings for that mode of operation, this case will cause data when accessing the data from time to time “lost” so that data can not be achieved, of course, can only re-read, so a lot of wasted time, of course, the efficiency of the system low, oh.

For example to facilitate understanding. Try to search all the rows and columns of memory, but if it is in the clock cycle and have not been able to complete the data read, then you have to wait for the next cycle, originally with a clock cycle will be able to solve the problem and now need to or even three to two clock cycles to complete, which significantly reduces the efficiency of the system. This time, more high frequency the more likely cause an error.

Cache Cache is located between the CPU and memory, temporary memory, Sony 19.5 v ac adapter is smaller than the memory exchange rate. The data in the Cache is a small part of the memory, but this small part of a short period of time the CPU is about to visit, when the CPU a lot of data is called, you can avoid the memory to be called directly from the Cache, thus speeding up the read speed . Thus, by adding Cache in the CPU is a highly effective solution, so that the entire internal memory (Cache Memory) both Cache speed and memory capacity of the storage system. Cache on CPU performance impact, mainly due to the CPU data exchange sequence and the bandwidth between the CPU and Cache.

Maintenance laptop battery properly to avoid the details of the misunderstanding

Posted on May 8, 2012 by Yedda

More and more users of notebook computers, notebook computers is how maintenance has attracted the attention of more consumers to friends; we all want to live and work completed in the fast and efficient learning at the same time, correctly and properlymaintenance of computers, in order to make their own books to maximize play its role in longevity. Following <a href=”http://www.usbphoneworld.com/apple-a1181.html”><strong>Apple A1181</strong></a> for you about one of the more important battery maintenance. Friend might be interested with the concern to understand!

Misunderstanding one: notebook battery without having to power all run out before charging

Notebook batteries are lithium batteries, lithium batteries, run out of battery again for a long time filled with do not have any role, or even harmful. Because lithium does not exist in the so-called “cache effect”, only the early nickel batteries have this feature.Laptop battery life in general with the man-made damage, or natural life. Basically, the battery life are fixed 300-600 charge and discharge times, generally available 2 years.

Myth: when the power is connected, the battery can pull or not pull

Pull and pull depends on the actual usage: Connect the DC power at the same time do not disconnect the battery and the battery does no harm, because the battery is fully charged, will not accept any electricity into the power will be directly to the laptop power supply supply system. But when the laptop high-speed operation, the internal overheating is best to remove the battery, otherwise it is harmful.

How to properly charge laptop battery

Should avoid the battery is run out of run out of recharge, because this will give the battery a lot of pressure resulting in damage. A more feasible approach is to charge about 20-30% of power remaining. In fact the notebook lithium battery in the number of “light / charge” is limited, all used to recharge will significantly shorten the battery life. At the same time, the battery should be charged in a dry place, Also note that the heat problem, which is the enemy of the battery.

Tips: mobile phone battery life with <a href=”http://www.usbphoneworld.com/apple-g415inch-a1078.html”><strong>Mac G4 battery</strong></a> is not the same, a lot of people may experience in the use of mobile phone battery to determine that the laptop battery should be all used up rechargeable, this idea does not.

How to save the face of long-term use of laptop battery

The laptop battery is to put the photoelectric save or should be filled with the power to save? Put the photoelectric long-term preservation of the batteries will lose activity, and even lead to the control circuit protection self-locking and can no longer use fully charged, long-term preservation will bring security risks, the best way to save is the will power to about 40% and then stored in a cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to take the battery out with time, can guarantee the battery good state of preservation, but not so the battery is completely lost and damage the battery.

Several measures of working hours to extend laptop battery
1> to reduce the brightness of the screen: you can use the fn + down / up key combination to quickly adjust brightness (specific the fn + which keys need to see their own laptop).
2> use of standby, sleep and other functions: when a long time without a computer, notebook standby or hibernate, saving power and extending the life of the computer.
> Open the cpu speedstep function, can greatly extend the battery working time: cpu speedstep function is the default in the bios to start when using the battery, cpu will automatically drop the frequency to use to save energy. If not open, you can boot into the BIOS, press F2 to find the Performance settings Speedstep the Enable to Enabled.
4> when using the battery, try to turn off the wireless, Bluetooth and infrared port.Removed without the use of peripherals and avoid enable large 3D applications, games, etc., to reduce unnecessary battery consumption.

When we pay attention to avoid these routine misunderstanding, it will greatly enhance the maintenance of their own batteries, thus extending its life; simple why not do it?

Repair Laptop Battery and Its Maintenance

Posted on April 17, 2012 by Yedda

(A) Battery causes of damage

Laptop batteries use a long time, often dissatisfied with the power, even the battery has been damaged, the concrete manifestation of the resistance is larger at both ends of the charging voltage rises faster. So easy to charge control circuit judge is already full, the capacity of natural decline. The relatively large battery internal resistance, discharge voltage decrease speed, so it is easy to mistakenly believe that the voltage is not enough, lack of electricity. Found the battery working time is relatively short, and should take appropriate measures.

(B) The battery refresh program to restore the battery discharge time

Brand laptop has a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650 laptop with battery nickel-metal hydride (Ni-Mh) batteries, usually improper charging and discharging, resulting in battery discharge time is getting shorter, leaving less than five minutes, if carrying a laptop to go out to work, it is very inconvenient, Is there any way to restore the battery discharge time?

Response to these circumstances, we can take advantage of IBM has launched a battery refresh program to refresh the battery put it back in the discharge time, the specific method is as follows.

(1) the use of AC power for laptops, the first to ftp://fip. the pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download software provided by IBM TP390/390e/390x series laptop battery refresh program.

(2) Restart the computer, press F8 to enter boot menu, and select the security DOS mode.

(3) enter the directory containing the files you just downloaded, and perform a battery the refresh the program isbr0lww, exe, after reading the warning message, and asked to insert a floppy disk, and then press the Enter key to execute the operation of the self-extracting.

The Upgraded Advantages from Lithium-ion Laptop Battery Replacement

Posted on April 11, 2012 by Yedda

We all know that one of the advantages of lithium batteries is that you can at any time at a convenient time for the lithium-ion battery charging, rather than have to want the power ran out after charge. So, what is the charge cycle? A charge cycle means that the battery power used by the full-empty, then by air charge to the full process, this is not the same as the one charge. Simply put, the 600 mA lithium battery, your first time charge from 0 mA to 400 mA, with the N mA with ah; and then you charge 150 mA, then the N mA ; charge and 100 mA, a piece of battery charge cycle to when the last charge to 50 mA. (400 +150 +50 = 600)

A lithium battery on the first day only half of the electricity, then it is fully charged. If the next day, that is to use half the charge, a total of two charge down, this can only be counted as one charge cycle, instead of two. Therefore, may often be that complete a cycle in a charge through several times. Each completed a charge cycle, power consumption will be reduced a little. This is why many people using the lithium cell phone often said: “The broken cell phone, just bought can be used four days on one charge can only be used three half days,” the reason. However, reduce the magnitude of this power is very small, high-quality battery charge cycle many times, will still retain 80% of the original electricity, many lithium-powered products in two or three years is still as usual.Of course, the life of lithium to eventually need to be replaced.

The life of lithium is generally 300 to 500 charge cycles. Assuming a full discharge of electricity provided for 1Q, without taking into account the reduction of the power after each charge cycle, the total lithium in its life to provide or to its complement of 300Q-500Q power. From this we know that, if each with 1/2 charge, you can charge at 600-1000; each with 1/3 charge, you can charge at 900-1500. So, if the random charging, indefinite number of times. In short, regardless of how charge, for a total complement of 300Q-500Q, the electricity that is constant. Therefore, we can also interpret it this way: the total charge capacity of lithium battery life and battery and the number of unrelated charge. Deep deep release sufficient and shallow release shallow charge for the life of lithium or less. , Some MP3 manufacturers publicity, said “certain models MP3 using powerful lithium battery, can charge more than 1500.” This is purely to deceive consumers ignorance.

In fact, shallow release shallow charge more beneficial for lithium, lithium to do calibration only in the power module, only deep put deep charge necessary. Therefore, the use of lithium-powered products do not have to rigidly adhere to the process, all to facilitate the first charge at any time, do not have to worry about the impact of life.

How to Figure Out the Value of Laptop Battery

Posted on April 10, 2012 by Yedda

I before mentioned the importance of the laptop battery, notebook overall level of performance and battery pros and cons are inseparable, that the importance of the battery must be no less than the CPU, motherboard, hard disk. Since the laptop battery is so important, the price naturally a lot of money. As far as I know, generally the price of the laptop battery $ 1000 — $ 3000, accounts for about 10% of the selling price of the notebook as a whole — 15%, some ultra-thin models or even higher. Example: Toshiba 1750 Toshiba 1750, the price is ¥ 9 988, it uses nickel-metal hydride battery is necessary to ¥ 1400. This can be seen, the high cost of batteries has also become an important factor in restricting the notebook price cuts. Compared to the phone, the proportion of the total selling price of the laptop battery is not too high, the price of mobile phone batteries are generally more than 30% of the total price of ¥ 1000 mobile phone, for example, the price of the original battery is about ¥ 300 , can be considered a large child. So here, to persuade you must treat the battery, whether it is a laptop or cell phone. If used improperly, causing the battery to the OVER, regret may be too late.
Second, the battery manufacturers to provide what kind of warranty?
We all know that the manufacturers warranty period of the notebook computer is generally 1 — 3. Can actually enjoy the longest warranty time, only the CPU, motherboard, memory, hard disk and <a href=”http://www.usbphoneworld.com/apple-a1175.html”><strong>Apple 15 Macbook pro battery</strong></a>; wearing parts, such as: CD-ROM, LCDs, such as Shell can only enjoy a maximum of 1 year warranty; As for the battery thing, Paul 3,warranty for six months, the longest, but one year; Some of the battery are not out of warranty, if the notebook buy a home the next day the battery died, you can only be bad luck. As market competition intensifies, the battery is not covered under warranty, is now rarely seen. However, radium or to remind you that before you buy a notebook, ask the warranty period and conditions of the battery, be careful not a big mistake.
Third, why is the battery warranty period is so short?
This issue and I asked some notebook dealers and manufacturers, their answer is: The laptop batteries are easily damaged goods, the frequency of recharging is constant, use a little time with hate a little less than half the reimbursement . Moreover, the laptop battery and other hardware, there is no room for repairs, only new, so-called warranty is actually a replacement. Long warranty (replacement) of such products, and intangibles increased the burden on manufacturers, as a for profit vendor who is not willing to bear such a big risk. It seems that the laptop battery 1 year warranty manufacturers to users greatly mercy.
Genuine laptop battery warranty is the case, the parallel even imagine. The sale of parallel imported merchants never refuses to talk about the battery warranty, users are rarely asked. Vendors are always battery generally no problem bad replacement and other perfunctory mention this sensitive issue. I can not want to lose the support of the parallel of the regular vendors accessories rely warranty battery? Are counterfeit products to deceive the user.

Laptop Battery Is One of the Luxury Consumables

Posted on April 9, 2012 by Yedda

Some of my friends that will dispose of batteries in the side do not have as much as possible, connect the power supply will not be pulled out, so can directly reduce the charge and discharge times, the battery longevity. In fact, in the relevant professional test can be found in the capacity of the battery itself and the surrounding temperature is too high, and secretly slip away Oh!

The small lithium in fact, very high temperature,
Test battery temperature, charging 100 percent state of up to 60 ° C, long-term to maintain this state three months after the battery capacity is decreased by 40%.Undoubtedly, the high temperature accelerated the decline in battery capacity, at room temperature until the battery is fully charged, unplug the external power supply as soon as possible to reduce the battery temperature, to avoid excessive loss of battery capacity.

In addition, the voltage stability in the process of laptop battery is also particularly important. The user should try to avoid the notebook power adapter and high-power electrical appliances (such as air conditioners, refrigerators, washing machines) received the same electrical outlet.

Small lithium timid, rain and thunder, scary
The reason is simple, high-power electrical appliances turned on or turned off will form a high-voltage transient and cause the battery damage during a lightning storm should try to avoid charging the battery. Conditional friends optional UPS devices (uninterruptible power supply, can provide sustained, stable and uninterruptible power supply), allowing users to have plenty of time to cope with a sudden situation.

Enough to be smaller due to lithium-ion battery memory effect is negligible, so halfway through the charging of their damage is not too great. In contrast, the BIOS discharge and external small bulbs, such as excessive discharge (full discharge), the detection of hazardous greater. Under normal circumstances, the large lithium-ion and lithium polymer battery, friends do not have to wait until the 0% to go charging.
Lithium-ion battery charge and discharge cycle test table:
Cycle life (10% DOD):> 1000
Cycle life (100% DOD):> 200 times
DOD is the depth of discharge, seen from above, rechargeable frequency and depth of discharge, 10% DOD cycle life than the 100% DOD for much longer. Under normal circumstances, there should be reservation in accordance with the remaining battery run out of the completion of the charge of the principle.
Front of the charging and discharging method is mainly for users often use the laptop battery. Part of the imprisoned or the Office of the white-collar workers, but more often directly use the external power supply. But previously said, the laptop battery when not in use will appear consumption, its indiscriminate charge and do not know the level of power consumption, might as well consider to extend its life by virtue of changing the battery charge threshold.
Threshold, a field or the boundaries of a system is called the threshold value called the threshold. Threshold, the charge that we charge set starting and ending point in the external power supply is open, the battery will be based on the remaining capacity to start or stop charging.

Effective ways about how to charge or discharge batteries

Posted on September 23, 2011 by Yedda

Toshiba has come a long way when it comes to the laptop computer battery life in their laptops, but that does not make them immune to the occasional hiccup. Poor charging practices may cause issues with battery life, & power-sucking settings can deplete a charged battery, an older, at a surprising rate. For plenty of Toshiba laptops, even temperature can affect whether & how your battery charges & discharges.

If your laptop computer is used, you have a chance to maximize your battery’s health from the get-go. CNET authors Asher Moses & Brian Nadel state that long-term battery vitality can be ensured if ‘when first using your laptop on battery power, [you] let the battery drain before you recharge it. Don’t recharge when the toshiba PA3615U-1BRS battery is only half drained. Do that for at least the first sessions.’ In case you continue to do this every time you use your laptop computer battery, you will extend the length of time your laptop computer can run on battery power.

Power Settings

Of the main reasons toshiba laptop computer battery life is so short on plenty of laptops is because of the power settings. You can access the power settings on a Toshiba either by right-clicking the battery tray icon in the lower-right corner of your screen & click ‘Power Options’, or by going to Control Panel > Power Options. Here, you can select the settings your computer will use when it is jogging on battery power, alter when the display turns off, pick when the computer will go to sleep, & select how bright your display is. The default ‘Power Saver’ settings alter the display brightness to about 40%, turn off the display after three minutes of inactivity & put the computer to sleep after 15 minutes. Think about which settings make the most sense for you, & alter your computer accordingly to save power.
