Battery Plugged in not charging and not detected solution

I have a Dell Vostro 1510 laptop, and when i have the battery charger plugged in, the battery icon says "10% available (plugged in, not charging)", and if i pull out the cord, the laptop shuts down straight away. Can this be fixed, and if so, how? I bought this laptop new around 6 months ago. The detail info below:


The Battery didn't charge or detect being plugged in also caused by four reasons:

  • 1. The Vostro 1510 laptop battery failed

  • 2. The Adapter failed (can not charge the battery)

  • 3. The motherboard charging electric circuit failed (many caused by short damage). You can view more info here: Dell Motherboard Problem

  • 4. The laptop bios is too old to recognize the battery

After I checked my battery and adapter and confirm they are good. Then I try to repair it by myself.. My Latitude E6400 battery was fixed by myself.

The first solution :I search in the google: Repairman from another site suggested that while the computer is on and plugged in, to unplug the adapter and then plug it back in again. To check the computer can started charging.

So I remove the laptop battery from the laptop and left the AC cord connected, booting it up on the power cord alone until I was able to boot into Windows 7, at which point I then put the laptop battery back into the computer while it was still on. This worked and while a tad unsafe for most people, I wouldn’t recommend you use this idea unless you absolutely had to, that is, if there was no other choice.

The Second Solution: You can download the newest BIOS from and then flash the bios. But I do not want to update Bios, So I use another way to make the Power manager system to recognize my latitude E6500 battery. :)

I open up my laptop Device Manager (usually a right click on your Computer/My Computer) and remove all Dell inspiron 6400 battery related devices from the Device Manager. Then after you’ve done that, right click again and select “Scan for Changes”, which should reinstall the proper services and allow for your laptop to charge again. See the more info in the image below.


If this also can not solve the problem, I suggest you send the laptop to Dell to repair the Laptop motherboard.

Dell tip for lithum laptop battery

Q Is it easy to install a battery?

a Yes, very easy. First, make sure all open files are saved. Next, either attach the aC adapter directly to the lap or set the system to "hibernate" mode or shut off. Release the latch on the current battery, and simply install the replacement Dell Latitude D830 Battery.

Q Will Dell laps accept non-Dell batteries?

a Dell has a rigorous qualification process by which all Dell batteries are validated to ensure proper function, performance and safety. Some non-Dell batteries are available in the market with claims of compatibility with Dell systems. Dell cannot verify these claims, nor the safety of using them in a Dell system. Dell strongly encourages our customers to use only Dell lap batteries advertised as appropriate for their lap model. Only Dell lap batteries come with a 1-year warranty, are engineered for optimal safety and performance for Dell systems, and are supported by Dell technical support for the length of the warranty period.

Q What is a modular bay battery?

a In some lap systems Dell offers a Latitude D620 Battery that can be used in the optical drive media bay (DVD/CD drive bay). This enables the use of two batteries, potentially extending the available run time.

Q If I install a modular bay battery, are my primary and modular bay batteries working at the same time to power my lap computer?

a No, the modular bay battery is used first, then the system automatically switches to the primary battery. This is a deliberate design to allow the most amount of run time to remain in the primary Dell KD476 Dell U4873  battery in case the modular bay battery is removed and replaced with an optical drive.

Q For what use is the strip of LED lights on my battery?

a Most Dell batteries have an LED indicator that allows users to see how much run time and how much overall battery life are available at the touch of a button.

To check Sony VGP-BPS8  charge, press the button and the number of lights that appear will tell you charge status. If all lights appear, you have a fully charged battery. Each light that appears accounts for approximately 20% charge.

To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition and approximately more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, approximately less than 60 percent of the charge capacity remains, and you should consider replacing the Inspiron 1100 Battery .

Q What does Dell recommend for battery storage for a long period of time?

a When storing for more than 4 days these guidelines can better preserve the life of your battery:

Do not store batteries for long periods plugged into or attached to any power source. This includes aC adapters and lap security carts plugged into an outlet.

Lap batteries, including those stored in lap systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).

Batteries may be stored in the lap or outside of the lap.

Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the laptop battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)

Q are there restriction with taking lithium-ion batteries on planes?

a Effective January 1, 2008, the Department of Transportation (DOT) through the Pipeline and Hazardous Materials Safety administration (PHMSa) will no longer allow loose lithium VGP-BPS9/B  batteries in checked baggage. These batteries may continue to be packed in carry-on baggage.

Asus Eee PC is becoming the history

The article is first posted in

Along with the Intel readjustment, after Netbook experienced a prosperous age, it become step into the old age. Asus and Acer are the first to announce stop developing & researching netbooks to follow the light & thin laptop battery comprehensively.?

According to relative media reported the two laptops manufacturers, Asus and Acer has already stop the develop working of this second half year but turn all the energy into the light & thin notebooks like Latitude D600 battery. This is mainly because Intel postponed the publication of next generation netbook flat roof Pine Trail-M and MID flat roof Pine Trail-D to the 1st quarter of 2010.

But there is some information disclosed that ASUS may promote Android flat roof netbook products the later of this year, but the publication date is after October. Besides, touch model flat netbook Eee PC T91/T101 products will be follow up after the official selling of Windows 7 with dell laptop battery.

Another side, for the light & thin laptops based on CULV flat roof, ASUS already prepared 12 inch, 13.3 inch, and 15 inch machine type, 13.3 inch is the mainstream products, and it will be increased 12 inch and 14 inch model in August as Ibook G4 battery.

For Acer, the netbook products are still promote 10 inch Acer Aspire One battery series as the main products. Regarding the light & thin laptops, Acer already own 13.3 inch, 14.1 inch, and 15.6 inch, three machine models, and plan to add the model with collocation of ROM and independent display card according to the needs of market.

The two leading manufactures stop developing netbook products to developing thin and small laptop (Powerbook G4 battery), it is not some goods news for netbook market and it will bring chain-reacting. Meanwhile, it also proved that netbook market has already passed and will be replaced by light & thin laptops.

Intel created a new class of low power notebook

the article via:

Sales of notebook PCs should rise a whopping 25.5 percent this year to 209.5 million units driven by growth in Sony VGP-BPS9 battery netbooks and a new class of low power notebooks created by Intel Corp., according to a new report from market watcher iSuppli Corp.

Despite the worldwide recession last year, consumers were enthusiastic about Sony VGP-BPS2B battery notebook PCs, a trend that will persist in 2010 especially for the markets two fastest-growing segments," said Peter Lin, senior computer analyst at iSuppli. The CULV designs should grow 93 percent to 14.5 million units in 2010.

ISuppli defines netbooks as portables costing less than $500 with display smaller than 10.2 inches. Mainstream notebooks still comprise the brunt of the market at 160.5 million units, and they are still expanding at a 21 percent VGP-BPS9/S growth rate this year, iSuppli predicted.

By contrast, AsusTek Computer Inc. which launched the netbook craze with its eePC design saw its market share slide from 37 to 21 percent last year, shipping 5.5 million Sony VGP-BPS2 battery netbooks. Hewlett-Packard, Samsung and Dell took third, fourth and fifth place in netbooks respectively.

Vista Notebooks (A)


Gives you faith the promises of Microsoft, Vista is optimally prepared for mobile use,especially Dell latitude d820 battery . Basically, the new Windows actually harmonizes neatly with mobile PCs. However, there are some inconsistencies, and key settings are well hidden. What hurdles need to take it, check out this article.

Hardware compatibility check

New notebooks deliver almost all manufacturers pre-installed with Windows Vista. The included drivers are usually adapted to the laptop hardware (like the Dell latitude d531 battery )and support additional features such as special input devices or the characteristics of the display.

It becomes more complicated if you want to upgrade an older notebook with Vista. For mobile computers are often equipped with exotic components for the Vista from the factory brings no suitable driver. We strongly advise you to check just before the update, whether the manufacturer of your notebook offers (for one thing ,the Dell latitude d630 battery )the latest Vista drivers. New drivers can be found on the website of the device manufacturer usually in support or download area. Still quite incomplete, the driver supply, especially for docking stations, fingerprint reader and multimedia components such as analog and digital TV cards

Optimize power plan for your needs

Vista recognizes a notebook environment when you first start and configure the power saving options automatically. Who optimized the rules can get out several additional minutes of battery life.

The settings can be found in Start, Control Panel, System and Maintenance, Power Options and Dell xps m1210 battery . Vista includes three power plans: "Balanced" for the network operation, "sleep mode" for mobile working and "maximum" (disable all power management). The respective energy mode is associated with a brightness setting, which can be customized by the user. While under XP and the power scheme 'Minimal Power Management "the speed of the CPU is dynamically adjusted, means" sleep mode "under Vista in any case a drop in output clock frequency.


New energy savings plans let the user create about "power plan" to add. The opportunities to fashion its own power plan are far reaching. Away from the usual parameters can be set here, for example, how will the wireless hardware or the search and indexing of Vista behave in battery mode,such as Dell vostro 1510 battery , Dell vostro 1400 battery and so on.

Hack laptop battery notice

In the last article, We introduce the way "How to hack dead laptop battery". But as far as we know the hack battery is a dangerous and perplexing work for the professional guy. Most of us only know how to take apart the battery pack and solder the cells to the circuit board, this may cause some damage to electrocircuit.

After using for a long time, the laptop battery capacity would reduce, resulting in shortened life of the notebook. This is mainly caused by an internal battery batteries aging failure. In serious condition, we cant solve the problem by battery calibration procedures or repeatedly charging and discharging. For this issue, many fans will open the battery case, to find the failure and replace batteries cells, they think that will be able to solve the problem. The actual situation is really so?

Carefully Replace the battery cells

Most laptop battery are made up of lithium-ion batteries cells, and lithium-ion Dell Inspiron 6400 Battery life is basically a constant, only 500 ~ 800 times charge life. Therefore, if the regular use of batteries for notebook power supply, 1 ~ 2 years later, due to the internal battery aging, it is easy to achieve the life of the batteries expire. Although we have detected in the open cell batteries, the show is a one or two damaged batteries. even if you replace the failure batteries, the battery return back to normal in a short period of time, it can not be used again soon as the entire failure of other batteries.

In that case, replace all the internal laptop battery can solve the problem? In fact, it is difficult to do this. Because in the original battery, its internal batteries is a precise match, and the capacity of batteries, terminal voltage and internal resistance are in a good consistency. And the battery we buy in the market has not been tested and matched, we can not matching for the batteries under the amateur condition, so the capacity, internal resistance and other parameters will inevitably vary. In the internal battery, the batteries are charged together after the series (in the majority of notebook batteries, the batteries will be divided into eight groups, four in series and then parallel to form a battery pack), as a result of the rechargeable battery the same current, in which the smallest capacity batteries will of course be full of electricity, while the other is not enough battery power, the battery terminal voltage can not set the voltage, charging circuit will continue to charge Dell Inspiron 640m Battery pack. In this way, the original fully charged rechargeable batteries will be over-charged.

To reduce the charge time, the current of laptop charging circuit is very big, it will produce great heat when charging, so the liquid batteries temperature and pressure rise, internal electrolyte easily dry or overflow , so the batteries capacity decline and even explose. The total storage capacity of the battery determined by one of the smallest capacity batteries, and this will turn into a vicious cycle, after repeated charge-discharge, the entire battery capacity will significantly decline.

At the same time, a number of laptop batteries in order to prevent unauthorized users to open the replacement of Vostro 1310 battery , have the smart chip protection and anti-line openings. As long as the shell to open the battery or batteries from the battery in the circuit board removed, intelligent protection circuit will stop the output of the battery. Even if we put the batteries back to the battery circuit board or close the battery case, the protection of its smart chip still can not be restored. In this way, the battery will not be able to normal output. We need to reset the smart chip in order to solve this problem, but the amateur conditions, we are unable to reset the smart chip. Therefore, from time to time change batteries cell may cause permanent damage to the battery.

So, how do we solve the battery problem? The best way is to buy a new original battery, but now a new original Vostro 1320 battery or even a few thousand dollars, to spend so much money is too high, exceeding the carrying capacity of many consumers. However, there are a number of professional notebook repair station, its equipment and technology are good, but there are some repair stations and manufacturers of batteries there is a long-term cooperative relations, the battery can be manufactured to precise matching. This will ensure the maintenance of quality.

In these places the price of batteries for about 300 million, although replacement of batteries on their own to higher prices, but will keep the dell vostro 1500 battery's long-term use. In addition, some maintenance stations for maintenance had also carried out a six-month battery warranty. And we use these six months, as long as there are a hundred times to ensure that the battery charge and discharge around, and battery capacity and stability during this period, then after the battery will enter a stable period, the damage is not easy.

Have know-how to maintain the battery

In any case, replace the batteries do not need our small price to pay, so we have to use in day-to-day attention to the maintenance of the battery to extend battery life.

To protect the battery, first of all to reduce the number of Vostro 1510 battery , that is to say when in the city, do not use the battery as much as possible. This can reduce the number of battery charge and discharge, longer battery life. While this caused some inconvenience to use, but every time you think about the use of batteries, need money to pay two dollars, or you take it easy.

The internal structure of the battery

Battery calibration procedures can extend the battery life, has been a subject of heated discussion. Support the view that correction can eliminate the battery memory effect of batteries to extend battery life. The opponents believe that the use of lithium-ion batteries have no memory effect, so the correction process will only increase the number of battery charge and discharge and shorten battery life. In fact, understanding these two are not comprehensive. Although lithium-ion batteries to reduce the memory effect, but the memory effect still exists.

Indeed the Vostro 1520 battery calibration can reduce the memory effect, but this is not the most important, the battery calibration procedure is to establish the main functions of the dell vostro 1400 battery and control circuit so that the control circuit can correctly identify the capacity of the battery, so to avoid battery overcharge or over-discharge phenomenon. At the same time, the system can also be exhausted before the battery shutdown to protect data security. However, the frequent use of battery calibration procedures will increase the number of battery charge and discharge. Therefore, we run once every three months about the battery calibration procedures it.

We in the use of batteries for notebook power supply or power adapter for charging the Vostro 1710 battery , do not unplug the notebook's battery. Because the battery is charging or discharging state, the currents are very large, if we try to plug the battery, then, it is easy to have a spark, not only will cause contact of ablation, may also be caused by the impact of current circuit board or battery laptop charging circuit damage.

In addition, many people there are still some misunderstanding on the use of batteries. For example, the "new purchase to go through the Vostro 1720 battery charging and discharging several times to activate," "notebook batteries do need to put a" matter of fact, with the memory effect of lithium batteries and battery to reduce the improvement of internal protection circuits. These factors impact on the battery capacity has been very small, we run on a regular basis as long as the battery calibration procedure of these operations will be able to eliminate the impact of the battery, so we need not care too much for this purpose to wait on your notebook, after all, the battery is used used.

Lithium battery explosion reason and prevention

According to the U.S. well-known science writer Marshall Brain series of articles in the lithium batteries introduction, the vast majority of lithium battery explosion caused by a short circuit, and the specific reasons, including charging overvoltage / over-current use of aging.

Lithium laptop battery manufacturing process, because the manufacturing process itself flawed, it is easy to be insulated in this between the two poles, leaving metal dust, copper foil, aluminum foil pieces. The angle is expected in the battery than the fever (more common in long-term use or charging), the like boiling water in a grain of rice, as in the electrolyte to make random thermal motion. If you happen to have the battery positive and negative particles or debris near the middle of the diaphragm level, it could create a divide perforation, triggering micro-short circuit. As the batteries are flammable organic electrolytes, micro-short-circuit may cause an explosion, burning and other accidents, generally have the following three cases:

1. Sparks ignited the electrolyte, and thus bring disaster to come into contact with plastic body and flammable, resulting in fire;

2. Was experiencing an increase of temperature caused by the battery, the discount laptop battery inside the space is small, perhaps because of increased pressure to explode;

3. Batteries slower rise in temperature, the battery case to melt gradually, so that corrosive electrolyte leakage.

Lithium Dell Inspiron e1505 Battery safety problems can not stop now, because then the advanced manufacturing technology, will inevitably lead to planting the seeds in the electrolyte "missile." Should be noted that the formal sector of lithium battery production and sales have strict norms of acceptable quality lithium batteries, the number and size of debris have been controlled within a small, very low risk of perforation of diaphragm; batteries outside the Shell also used flame-retardant material, is not prone to fire.

The explosion-proof lithium battery of measures

Lithium Dell Inspiron 6000 Battery safety problems, the battery manufacturer, of course well aware, then what they used explosion-proof measures? Li-ion batteries for notebook computers, for example, its working principle is: Lithium batteries near full charge and discharge almost drained when the voltage drop, the control circuit detects this situation, notify the protection circuit cut off power supply to prevent overcharge or excessive discharge, so as not to shorten battery life.

The current notebook lithium batteries possess a more complete multi-level protection mechanism, even in the power charger, notebook computers unusual circumstances, the Dell Inspiron 1300 battery laptop can also be converted to automatic protection status, is generally not an explosion. But once the control circuit and protection circuit of the ability to work reduced hours, the battery on the verge of "dangerous" the. Mobile phones and other electronic products, lithium battery charge and discharge protection mechanisms, similar to this.

Do not need it "at arm's length"

In recent years, lithium-ion electronic products explosions often found newspapers, aroused a lot of consumer panic, some people for their own mobile phones, MP3 charging often "at arm's length"; also because of fear, simply a long-term will be cast aside Dell laptop battery, cause scrap. However, survey results, the majority of lithium battery explosions are the result of the user pay attention to safety tips, such as unauthorized modification, use of non-matching charger, the A1175 A1079 battery placed in extreme environments such as making.

Should be pointed out that the lithium technology as a kind of after 30 years of study, has successfully commercialized the mature technology, its safety is guaranteed. Regular brands of lithium batteries at the factory will have been numerous Road test procedure after they are sold as well as information feedback mechanism in order to recall the product in question in time.

United States Transportation Security Administration (TSA) is given following the recommendations of the safe use of lithium batteries:

1. Using the original charger: Li-ion battery charging time is the high period of bombing. Than the original VGP-BPS5 VGP-BPS2C battery charger is compatible with the battery charger to ensure better security.

2. Use of a reliable battery: try to buy original Sony laptop battery, not to save money to buy "second-hand goods", such batteries may be through maintenance, and reliable than original batteries.

3. Do not place the Latitude D620 battery extreme environments: high temperature, collisions, etc. are all important causes of battery explosion, as far as possible so that the battery is in a stable environment, away from the high-temperature areas.

4. Do not attempt to modify: the phone is a sophisticated communications equipment, in the design, manufacturers will have on its security, strictly textual research. After modification, the battery may be at not taking into account the environment before, an increase of security risks.
