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.

How to test a dead Battery Charger

The dead battery charger means the charger can not work : can not charge the laptop battery or can not run the laptop. When our laptop battery can not charge, we must check the battery and charger state. Now let me list the steps of test our battery and charger below.

Make sure the powerbook g4 battery charger cable is plugged in and the output is to power.

Look closely at the battery. Is there corrosion or leakage? If so, replace the inspiron 6400 battery immediately.

Test the charger. For DC chargers, a voltmeter set at 25 VDC and touch the contacts with the probes. The meter should read about more than 1 V Evaluation of the shipper. If the reading is zero, change inspiron 6000 battery catheters.

Testing a AC charger through the establishment of a voltmeter to 25 VAC. Tap the contact probes. The transformer in the pa3399u 2brs charger is bad if you get no reading.

Check contacts. These are strips of metal or points in the appliance and charging cradle. With the Dell latitude d600 battery charger unplugged, clean with a cotton swab. Use a fine emery board to remove visible corrosion.

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.

Customer Review:

I have had other laptop batteries lasting well over two years. This one really disappointed me. It looks like in order to cut costs, Dell may have sacrificed quality.

From the looks of it, many people are having the same problem I have with the laptop battery. The 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 Dell Latitude D830 Battery last about 3 to 3.5 years before this happens.

The Dell latitude D830 battery replacement reivew in Amazon:

I have a Dell D830 (purchased 1.75 years ago) & a Dell D820 laptop (purchased about 3.5 years ago). The batteries are interchangeable in these 2 and the old D820 battery has begun failing to hold charge so I bought the AGPTEK Super-Capacity Li-Ion battery. The Latitude D820 Battery arrived DOA, no status lights and neither Dell recognized it. I sent it back for $8.70 in postage and the replacement does work and so far is reporting a good charge: 3.5-4 hours in the Dell D830, which is about the same as the 1.5 year old battery reports. The replacement is only a month from manufacture if I read the code AGPTek pasted on it (it has 20090720 embedded in it), and both the dud and the replacement fit well in both my Dells. However with the cost of shipping the dead battery back this battery was not such a bargain.

Purchased the Dell Latitude D820 Battery in Nov 2008 and it worked as advertised for between 6 and 7 months. At that point it quickly lost the ability to hold a charge. It still works in that my laptop can run for about 15 minutes on the battery, however the battery has bottomed out and only accepts ~20% of the capacity it had when new.

My experience with original Dell batteries is that they last about 18 months, however the cost is much higher.

This replacement battery for a Dell Latitude D830 Battery lasted 3 months before the charge wouldn’t last more than an hour. The original battery would run for 3.5-4 hours on a charge, and lasted for over a year. Now at 5 months on this battery, the computer tells me that my battery is "reaching the end of its useful life".

Dell tips about battery life store charge

Q How long does a Dell laptop battery last? When should I consider replacing mine?
A All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new Dell Latitude D610 Battery  when the run time does not meet your needs.

Q How should I choose between two batteries with different Watt hours (Whr) available on one system?
A Higher Watt hours (Whr) on the same system under the same operating conditions will generally deliver longer Dell Latitude D620 Battery  run time. For example, if you compare the same system, running the same applications, the 53Whr battery would provide approximately 65% more run time than the 32Whr battery.

Q How long am I able to use my Dell lap on a fully charged Dell U4873 Dell D5318  battery?
A Many factors affect the amount of time that a portable computer battery can deliver power before it must be recharged. These factors include the configuration (processor, memory, etc.), types of applications being run and display brightness.

Dell uses industry standard benchmarks for battery run time claims. For more information on battery run times and benchmarks, the white paper, “Understanding Battery Life in Portable Computers” is available at:

Q How do I charge my Dell GD761 Dell 75uyf battery?
A The battery charges in the lap when the lap is connected to an AC power source via the AC adapter.

Q How long does it take for a Dell lap battery to fully recharge?
A The charge time varies depending on the system. If the system supports ExpressChargeTM , the Dell Inspiron 6000 Battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.

Q What is ExpressChargeTM ?
A For a system advertised as having the ExpressChargeTM feature, the battery typically will have greater than 80% charge after about an hour of charging and fully charge in about 2 hours with the system off.

Q Should I totally discharge, then recharge my Dell lap battery occasionally to make it last longer?
A No, discharging and charging does not increase the life of a Lithium Ion technology Inspiron 630m Battery.

Q Can a Dell lap battery be “overcharged”?
A No, the battery is designed to s using the charger when it reaches full charge.

Q When docked or AC adapter is plugged into a wall outlet, am I using my battery charge?
A No.

Q Does Dell sell external battery chargers for Dell Inspiron 510M battery?
A Dell offers a Datamation battery charger for large institution customers. The charger has 16 charge bays to charge batteries for Latitude D500/D505/D510/D520/D600/D610.

Change the battery cell is not a good choice

When we want to repair our laptop battery, we often see some laptop battery maintenance introduce the change battery cell service. You just spend 30$ or less to repair original laptop battery by change the battery cell. As buy a new original laptop battery may cost you 200 $ or more. It looks great but it is really worth?

It has some risk when changing the original Dell Inspiron 1520 Battery cell. The batteries can be changed, it is very simple because the battery inside is just some series and parallel battery packs. But the corresponding protection board can not be replaced.Most of the protection boards are added secret infomation the time in the factory , only can be debugged in Dell laptop battery production plant.

Battery Protection Board are based on the corresponding matching Dell Inspiron 1521 Battery packs to debug a good, if the random replacement of batteries while protecting the panel without doing the appropriate debugging shield of protection features may fail, so the risk is relatively large.

Another point, if a single change batteries, then is a bad, because the internal resistance of the old and new Dell Inspiron 1721 Battery do not like the efficiency of the battery pack will drop a lot, but for the life of the new batteries also have a significant impact, and we manufacturers to replace the batteries are replaced all the batteries.

Generally laptop battery life is 1-2 years, so the Dell Inspiron 1720 Battery in the warranty period, warranty or replacement directly to vendors, it is better to buy a new battery replacement when out of the warranty period. After all, the cell-change battery may damage your expensive laptop.

Re-understand notebook lithium battery maintenance

Li-ion batteries in a life cycle in general can be 300 to 500 times charge-discharge. So many people think that, as long as using less battery, so that you can to a certain extent, played a role in extending battery life. But they did ignore the original Dell Inspiron E1705 Battery that the physical nature of the end when the battery off the assembly line, it’s internal life, the clock will then start walking.

So even if you do not set aside the battery, lithium Dell Latitude D510 Battery life was only two to three years you can come to an end of. Battery capacity caused by reasons for the decline was due to oxidation caused by the battery internal resistance increases. When the electrolytic cell resistance reaches a certain point, although this time the battery still be full of electricity, but the battery has been unable to release the stored electricity.

Caused by lithium LIFEBOOK T4010 battery is the speed of this aging temperature and set aside when the charge state of preservation decision. I will give a table to illustrate the different situations of these two factors, the impact on the battery capacity.

Can be seen from the table, high charge state and the high temperature accelerated the decline in Lifebook T4220 battery capacity. Therefore, if possible, as far as possible, after the battery charge to 40% placed in a cool place to save. This allows the preservation of a long period, the battery protection circuit is in its working state. And if the battery is fully charged, will be placed at high temperatures, which will cause great damage to the battery, the table has also been seen, charge 100% in the 60 ° C environmental conservation, 3 months after the battery capacity fell by 40% .

Therefore, how to save the battery solved the issue, but also leads to another focus of everyone has been argued, that is when we use a fixed power supply when there is a need to remove the Apple A1148 battery? Before the resolution of this question let us first analyze the use of fixed power supply when the battery placed in a computer environment in which … … at this time due to charge notebook computers role in protection circuit, so that the battery remained at 100% of full power state, and this When the battery in which the ambient temperature between 25-30 ° C, at least, if the hot weather, this temperature will be higher, then from the table, you should be very natural to come to a conclusion that it is so to do this would actually damage the battery, causing a decline in its capacity.

But despite the use of laptop computers, high-temperature will bring damage to the Apple A1175 battery. But Qudiao battery, use only a fixed supply, there will still some danger that dust and moisture will cause some damage to the battery, while the use of notebook computers in order to avoid a sudden power notebook computers may cause damage, so Manufacturers generally warn users not to remove the battery. Of course, this result will be naturally imagined, your battery as often in such a relatively poor environment, it will not be long over, and then you will need to go to repair center to replace the battery, this way, the benefit of course, is a manufacturer.

Finally we spotlight a lithium battery that is exactly how a reasonable charge and discharge this issue. For the lithium battery is best for partial discharge, rather than fully discharged, and to as much as possible to avoid frequent full discharges. Regular Apple A1185 battery too low discharge of the result can only be scrapped so that the battery in advance, because if the battery into every cell of 2.5 volts below the battery’s internal safety circuitry will be switched on, this time the battery will become some bad spent. Therefore, in order to avoid such situations from occurring, do not save the battery power before its release was erased, but rather a number of electric charge in the store before, and again before the first fully charged.

All in all, in order not to make your premature loss of the role of the battery, then the use of normal, you should try to comply with the following principles:

A. avoid full discharge, and often for lithium batteries. The repeated arbitrarily rechargeable lithium Toshiba PA3331U-1BRS battery damage is very small, almost negligible.
B. will need to keep hold of lithium batteries placed in the shade, remember not to put in the refrigerator. Avoid placing hot car, such as a long time to save the battery charge to 40% in place.
C. most of the time if you are using a fixed power supply, please remove the batteries placed in the shade.
D. no need to purchase spare lithium batteries for storage, so this piece is actually a waste of Toshiba PA3356U-3BRSbattery.

Battery is brought to use, as long as the attention to rational use and preservation methods, there is no need to care for their excessive, making it possible for its owners contribute more to performance is the most important.
