The laptop 6 mainly hardware problem and prevention Methods

1: Motherboard

Ask the guys who repaired their notebooks around you, the motherboard issues may be the most commen problem of Dell Latitude D410 Battery. The author’s first notebook also dead as the motherboard problem. General board problems reasuly the machine unbootable. Motherboard problems usually cases short-circuit of IC (integrated circuit).

We usually should change the motherboard when it is broken. The motherboard prices accounted for 1/4 of the laptop Dell Latitude D610 Battery price, so the motherboard problem is the most expensive problem. We need to take attention that do not let leak fluid into the motherboard (we often do this). Do not refresh the BIOS if neednot. In addition, the motherboard is the breakdown by high voltage also happened frequently. If in the electricity peak or just to restore the electricity blackouts, during lightning storm, I propose to use Dell Latitude D410 Battery-powered, do not access home electricity.

2: Hard Disk

The laptop hard drive is more unbreakable than PC hard drive, but they are still afraid of falling repeatedly. Take a look at the label that prompt us to do not throw it. Why? The notebook hard disk is smaller than PC, but the principle is the same, and also due to the complex composition of electronic components. Although the manufacturers optimize the Dell Latitude D520 Battery laptop hard drive break quality. Because of its own composition, it is fear of shock. Remind you, in the bumpy transport, do not use notebook. Be careful not to fall to the ground when place your notebook on the table. As the laptop hard drive is cheap, the information inside is priceless.

3: LCD Screen

LCD is a relatively weak and fragile product of Dell Latitude D630 Battery. LCD mainly make of the glass and liquid crystal, tube composition that are fragile parts. The LCD under organic cover protection, but the protection is very limited. Do not place heavy objects on the LCD, or it would fracture the glass layer. Pay attention Do not let the books hit a hard object. When accidentally dropped on the floor, Dell Latitude D830 Battery LCD is also often bear the brunt. The large LCD value is also a quarter of machine, and it is difficult to repair it but buy a new one.

4: Strings parallel interface

These interfaces do not support hot swap. It is easy to burn the string parallel when plug the USB port or other sevice in Dell Latitude D820 Battery power on. Even worse, resulting in short-circuit board scrap. Although changing string, parallel port is a not too expensive, it is troubleful. There may be someone would say: we are now almost not using the strings parallel port, let them go bad. But the notebooks for engineering debugging that can not lack of the two interfaces.

5: Touchpad

In Summer our hands are dirty and wet. Touch VGP-BPS2 Sony VGP-BPS2C pad with your fingers will make the coating above soon disappear, shorten the life of touchpad and keyboar. So we should wash and clean our hands before open the lapop?

6: CD-ROM

The CD-ROM broken are always caused by someone special love of watching DVD movie. We all know that the original Sony VGP-BPS2C Sony VGP-BPS2A notebook CD-ROM are 150 dollars or more. If always watching disc, your CD-ROM drive will die after one year. If you like watching movie, it is better to buy a DVD player. I just use my T40 combo CD-ROM to installing the software, burn backup, not do other things.

The analysis of the laptop battery replacement cost

With the growing popularity of notebook computers, laptop battery is getting more important to consumer attention. A good laptop battery is not only give the great convenience for user’s mobile commerce and digital lives, but also can eliminate insecurity of future use. A bad laptop battery, for the user unable to meet their mobile digital life. It will also bring the hidden dangers to users, especially security issues. A battery explosion caused the destruction of a notebook, or even ohter serious consequences. So choose a good laptop battery is significantly thing.

However, the thinkpad x40 battery original price is hundreds dollars. So that many users used to choice and better cost-effective laptop battery replacement. The laptop replacement market price is between 30 - 100 dollar. So it is difficult for consumers to judge its quality from the price.

In this article the author will help the customers to choose the best thinkpad x41 battery from the current market. We will analyze the composition and design of laptop batteries to compare the battery price and quality.

Laptop battery is made up of a lithium-ion 18650 cells with protection circuit board and PVC plastic shell. Then we will analysis of their costs on item in the follwing steps:

1. There are three kinds of 18650 lithium-ion battery in the market: 2200,2400,2600 mA. A typical ThinkPad X41 Tablet Battery with six battery assembly (Series 2 and 3). If it is a genuine original batteries, typically Japan and South Korea or domestic manufacturers A formal 18650 cells. These batteries have the quality and safety assurance through rigorous testing, the cost is usually in the 3-4 dollars (based on the different capacities). So a normal laptop battery (6-cell) costs around 20 dollars. If B grade, or batteries disassemble from the old machine (the quality and even safety issues batteries from Japan and South Korea). Their price between 1.5-2 dollar. Such Lenovo Thinkpad X61 battery assembly or re-assembled into a 6cell laptop battery cost 10-15 dollar. In addition, even worse, some manufacturers use more poor illegal 18650, often have security problems (that can cause the battery explosion), its 6cell laptop battery only cost 8 dollar or less.

2. Laptop battery PCB control panel : a good control panel can extend laptop battery life and protect the safety. Its cost is usually 10 dollar; If it is bad dysfunction PCB ThinkPad X60 Battery control panel, or board disassemble from the old machine, its cost is only 5 dollar.

3. Laptop battery PVC plastic shell, the cost of a good plastic shell is 5 dollar, a bad Lenovo thinkpad x200 battery low-quality goods cost less than 1.5 dollar.

4. Labor, equipment, venues, with an average around 4 dollar each cell.

On the basis of the above , a good quality assurance laptop battery such as VGP-BPS9/S (6 cell) costs should be at 40 dollar. So a good 6Cell laptop battery replacement price (including operations cost and profit) is oftern 60-80 dollar in the market ; If it is a inferior quality goods, the market price is 40-50 dollar; If it is the lowest quality laptop battery (the cell and PCB control panel are both disassembled from the old machine), the price is 30-40 dollar.

In all the laptop battery quality is as its price. We should buy the suitable Sony VGP-BPS8 battery in the market, do not take too much attention to its price or it is orginal item or not.

Power your notebook with any battery

As we all know the laptop battery is important to our laptop. Some times when your laptop battery run out in the open air, what should you do? Go home to get a replacement. No no you need not. Take out your torch battery to power your laptop.

In fact, laptop batteries can be replaced with any other kind of offers it is right or sufficient voltage. Here I am with two 6V LIFEBOOK T4010 battery manipulated up to twice the voltage to the power of a Compaq Armada 110th.

Step 1 Remove power

All you need for your old Fujitsu Lifebook T4020 battery to disassemble the battery, I was very stubborn and I have it only with a considerable distance to cosmetic damage, please try to set it apart from the contacts when the battery is connected to the laptop, I have but not real pictures of this step, as I have about 1 month ago, and I just un-earthed casing of the battery when you’ve received a little wrung from the battery housing to things either easier or a little more difficult was the Battery Compaq merged, so I was almost broken just plastic!

After the Lifebook T4220 battery unless you have some 9-cell battery, depending on the type of laptop was to find battery. You need to pull out all those bulky batteries, which certainly does not lead to rip the wire to the batteries from the board (Figure 2)

Step 2 Source improvise and power

To some batteries in the laptop, I have two Fujitsu Lifebook T4310 battery in my 5 million candle power torch, to assess each 6V to 12V to get as they were manipulated together for combined power, power, I do not know how long they modified battery is fully charged, but I guess at least 30 minutes. 100% CPU

If you have two batteries you need to red) to positive (a battery to the negative (black connect) from the other Fujitsu Lifebook T4410 battery .

Step 3 Connect power.

Now that they’ve been getting your Fujitsu Lifebook T5010 battery, the next thing to do is connect them to the leads of the laptop battery board, you have the positive of your new batteries to the positive lead connected to the PCB. I recommend that the cables of a decent length for a simple, but also tinged with red and black wires to the corresponding compounds battery (ie connected to red, red), it makes things easier.

Step 4 Replace remastered Battery

I had a small hole for the wires to pass from the Dell Inspiron 1721 Battery case, remember this and to do, so that the cables come in a handy place to do this if you do not want to spoil your battery housing provides good.

Step 5 Testing the new power

It must be said that I use to boot to the A / C power connector on the laptop, but after that it worked well without the A / C had power, I do not know if this because the laptop is old and it couldn ‘t was you know the batteries to boot the laptop, but it does recognize the Dell Inspiron 6400 Battery with the A / C power is connected and switched off the laptop.

The waste heat improve the 100% battery life of laptop ana cell phone

If we use every gadget or as a means of comfort that we know that these devices consume energy. But the Dell Inspiron E1405 Battery energy is not used by devices. A portion of the energy is lost in the form of friction and heat. For example, if we will use the power of computer processor chips, motors and power plants, there is a need to get rid of excess heat is not the equipment will not perform to their optimal level. Now, researchers have to think about the use of these Dell Latitude D410 Battery wastes energy. Peter Hagelstein is the co-author of this concept and is an associate professor of electrical engineering at MIT. His paper was published in the November 2009 issue of Journal of Applied Physics.

When this Dell Latitude D620 Battery energy is wasted, we could cleverly exploited the use of mobile phones double talk time without insert it again and again to recharge. The same could be the case with our laptops, we do not recharge it too often and could also reduce wear and tear. The revised and overloaded power plants can use shell more power when its wasted heat energy can be used.

Hagelstein is of the opinion that the current solid-state devices using excessive heat and convert it into electrical Dell U4873 Dell D5318 energy are not very efficient. He works with his graduate student Dennis Wu as part of his doctoral thesis to find out practically reliable heat converters, which does not carry us his predecessor’s drawbacks. They are gunning manipulator for a realistic technology to come to the realization of the theoretical limits for the efficiency of conversion could.

Postulates that such Dell GD761 Dell 75uyf energy can never go beyond an accurate reading than the Carnot limit. Carnot limit was in the 19 Century, founded. It is a formula for determining the maximum efficiency that the machine can achieve in converting heat into work. But the fact is, in practice, we have reached only about one tenth of this limit. Hagelstein, in close collaboration with Yan Kucherov experiments carried out by a different technology. They have the enviable efficiency as high as 40 percent of the Carnot limit reached. Furthermore, their statistics show that this new type of system could ultimately up to 90 percent, the ceiling.

Hagelstein, Wu and others do not try to improve on the existing equipment. She began again without any past baggage. They use a very simple system in which Dell Inspiron 6000 Battery power was through a single quantum dot state-generated device. This device is a type of semiconductor in which electrons and holes are very confident in all three dimensions is limited. So they tried to understand all the functions of the device. This helped them to better understand every aspect of such a machine.

Hagelstein says that he wants to not only convert heat into electricity, but he decided to do this by achieving a lot of XPS M1210 Battery energy in return for. He also admits that the current technology is available to use, heat output, but start with one. It’s as high-throughput power. It converts heat from a less efficient system and you get more energy. But this is bigger and more expensive system. After Hagelstein “It is a compromise. Either you get high efficiency and high throughput.” But the team found that with their new system, it would be possible to get both at once.

Hagelstein and his team studied a recent paper by MIT professor Gang Chen carefully released. They talked about closing the gap between the hot surface and the conversion device. They suggested that this Dell XPS M1530 Battery scheme is very important for improving performance. Gang Chen said that the heat transfer could be between very closely refrain surfaces at a rate that is orders of magnitude higher than those predicted by the theory. The new report provides a further step, the heat can be transferred not only to be turned into electricity, so they can be used.

Robert DiMatteo heads a company MTPV Corp. (for Micron gap thermal photovoltaic). DiMatteo is ready to commercialize new Hagelstein idea. He is quite confident that the technology developed by his company to a tenfold improvement in Inspiron E1505 Battery performance over existing photovoltaic devices shown. He plans to market the technology next year. At the same time Hagelstein would give the work of the required impact and a further ten-fold or greater improvement is possible.

DiMatteo presented his statistics and says that globally, if we consume fuel or a power plant generates electricity for nearly Dell Latitude D800 Battery 60 percent of all energy is wasted. This waste is usually in the form of heat. 60% substantial amount. DiMatteo is now hope that the technology to make “it could possible to recover a substantial portion of this energy wasted.”

Hagelstein is of the opinion: “It is a gold mine Dell Latitude D600 Battery in heat, if it could convert. A lot of heat is generated to go to places, and much is lost. If you could recover that your transport is technology, better . work “

Dell Lithium-Ion Latitude D630 battery Review

The Latitude D630’s 14.1in. wide-screen display is remarkably bright (223 cd/m2 in our Labs measurement). Its 1,440 by 900 native resolution is as sharp as some desktop replacements. With its standard battery, the Latitude D630 weighs 2.3kg. And the standard battery can last about 2-3 hours. We all know that the batttery is the most important accessories of laptop for mobile using. So I specilly introduce the laptop battery for you.

The Dell latitude D630 battery Tech Specs

• Technology: 6-cell lithium ion
• Capacity : 55Wh
• Voltage: 11.1V
• Weight: 311.50g
• Colar : Dark Grey
• Work with : Latitude D620 battery, Latitude D630 battery

The Dell Latitude D630 battery official introduce: Always on the go? No more worries about running out of battery power! You can power your wireless keyboard with this 6-Cell Lithium-Ion Primary Battery from Dell™. With a capacity of up to 56 WHr, the battery lets you work seamlessly when you are on the move for business trips or vacations. This battery provides uninterrupted reliable performance you need to get the most out of your system. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.

The Dell Latitude D630 battery customer review :

The Dell D630 battery that was included in this D630 laptop was unusable within a year of owning this machine. Dell will not replace their own defective part because it has been 1 year and 1 week since the machine was delivered. This laptop has already had the hard drive and the power cord replaced and based on other reviews, there is clearly a problem with the battery. After spending 45 minutes on the phone with technical support and no access to a supervisor, I will not use Dell to replace this battery.

From the looks of it, many people are having the same problem I have with the laptop battery. The Latitude D630 battery was giving decent run times until it reached an age of about 20 months. After that, it went to about 10 minutes of run time.While this is not an absolutely horrible lifetime, I typically have had batteries last about 3 to 3.5 years before this happens.

The Product Dell Latitude D630 battery replacement in Amazon review:

My battery lasts for 2 hours after 2 weeks of use(after following best practices of charging/discharging) which I would consider poor performance even after relatively cheaper price as compared to Dell battery that would last for at least 4.5 hours after 3 months of usage. I had to struggle a lot to fit the battery on my Dell D620. I would think twice about buying cheap as it may also be cheap in performance. I could not locate the contact number for this vendor as they don’t print it on their payment receipts. Why would any vendor not like to give its customers a customer service number to call unless they are expecting return of goods instead of repeat customers

Physically, this item is nearly identical to the Dell branded battery. There are no quality issues at all. It does have the battery meter on the bottom, just like the original one. Since my Dell unit crapped out after 18mo, I can’t do any side by side comparisons, but I think the original unit had a bit more capacity. I recall getting 4 hours on my D620 running Fedora Linux (thought that was for maybe the first couple months). This unit is maybe 3-3.5 but again, I haven’t really done any scientific tests. It could be that I’m just harder on the Latitude D630 battery now than I was then. Either way, it’s a steal at roughly 1/3 the cost of the Dell unit.

Hopes that help you. The next we will introduce the Sony Newest laptop battery: Sony VGP-BPS8 Sony VGP-BPS8A Sony VGP-BPS8B Sony VGP-BPL8 Sony VGP-BPL8A

The 10 factors that can affect Laptop battery using time

The process of using notebook computers, some factors that make the battery wear and tear. Even the laptop battery maximum using time less than the standard battery life, it not means the battery have some problem in inherent quality and performance. Notebook battery capacity mainly determine by the size of the marked mAh on battery. The size of the laptop battery MA hours directly related to the using time. Battery using time are also have a great relationship with notebook configurations.

Then we list all the specific factors that can affect the Dell WW116 battery life:

Factor 1: the processor speed - install the the right Intel chipset driver will enable the system to use Intel’s Speedstep technology, that can adjust processor speed in application system to extend the battery life.

Factor 2: Reading CD, DVD, CD-RW and hard drive frequently- the CD-ROM copy of the file directly to your hard drive, watch videos, dials and other operations will affect the Latitude D620 Battery life.

Factor 3: the total number of memory- if the system opens a lot of applications will take up a lot of hard disk space to do file-swapping (virtual memory), resulting in frequent hard disk read and write.So increase more memory will increase the battery using time .

Factor 4: Some applications to run automatically in the background, it will increase the CPU load, resulting in reduced Latitude D520 Battery using time - We usually suggest that turn off some background programs in the daily use, only run the necessary applications.

Factor 5: LCD’s brightness - the lower the brightness the longer battery using time if possible. You can use keyboard function keys to adjust the LCD brightness .

Factor 6: Power Management and Speed Step settings - Set the different power scheme in the power management will affect Inspiron 1720 Battery using time.

Factors 7: Battery life - the average battery life is one year, the gradual reduction of battery usage time is normal as the using. We also think it is the battery aging time.

Factors 8: For the processor and system equipment deeper applications (such as watching DVD movies and 3D games) will make the Inspiron 1721 Battery using time quickly reduce.

Factors 9: Wireless devices and Bluetooth devices will accelerate Dell XPS M1730 Battery consumption; When do not need wireless, you can use the keyboard function keys to turn off the wireless and Bluetooth to save power.

Factors 10: The environmental temperature - too high or too low ambient temperature will affect battery core activity of chemical substances, thus reducing the battery using time and life. The factors is happend obviously in Sony battery as Sony VGP-BPS8 VGP-BPS9.

Overall, the laptop battery using time is not only determined by capacity mAh, the hardware energy-saving technology is also very important.

Where is Laptop using heat come from

We are using the notebook for some time. Weoften found that notebook slowly get hot after using for a while, especially the bottom of laptop. The situation occur frequently in Summer. Where is laptop using heat come from?

When the machine overheating, some harm reasult happend: laptop system halted, restart, and even laptop parts burn (espacilly laptop battery). Which laptop part produce such a large amount of heat? Here I will give us a presentation.

As the desktop CPU’s power consumption and heat is very large. It can not be used in notebook as Dell WW116 , so mobile processors is specifically designed for notebook. Many notebook CPU processor power consumption are over 20W, particularly in the mobile Pentium 4 processor. Though there are a lot of technology tips make notebook average energy consumption low, but the peak is still very high (more than 30W) when using. Many of these energy consumed will come into heat dissipation. Therefore we should always check the clearance of xps m1730 battery CPU fan air vents. Make sure there are no stolen goods block the air vents, that cause the heat can not dissipate. If the notebook CUP silicone hardening, we should replace it in time.

First, the XPS M1530 Battery notebook cooling heat is mainly come from the CPU working heat. But CPU heat is not the all. And the early CPU processor heat is not very large. Just use some simple passive cooling method that can satisfy the cooling needs of the machine. That is the heat sink cooling as we usually known. However, as the continuing escalation of CPU processors, while in the Pentium processor century, the processor’s cooling is the big problem.

Secondly, the graphics card heat is also a large proportion. Early graphics cards heat is not large, but now a lot of high-end machines such as Inspiron E1505 Battery Inspiron E1705 Battery often configure the ATI Mobility Radeon HD4750 or GeForce GT240M such a good graphics card, so the heat also increase a lot.

Finally, there is some other hot parts, such as memory, hard drives, laptop battery, are also a number of laptop heat source.

How to charge your laptop battery properly?

During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.

For early notebook batteries as Dell XPS M1730 Battery (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.

In fact the lithium batteries has a little memory effect. The lithium VGP-BPS9/S battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.

A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had “full” level.

Sometimes WINDOWS show that ThinkPad R40 Battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery

So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the IBM ThinkPad R50 Battery. This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.
