Laptop battery does not charge

With the growing complexity of laptops, notebooks and netbooks, figuring out why a laptop battery does not charge is not easy. IBM Laptop Battery that suddenly die or notifications like “laptop battery not recognized” trigger valid reasons for suspicion. Even more — simply replacing a laptop battery is an expensive affair and certainly not always the solution. Nowadays there are many components involved in charging a laptop battery. In this story you’ll find a simplified approach to narrowing down a laptop battery problem and possible leads to a solution.

Simple PA3636U-1BRL Battery charging diagnosis

The simplified diagnosis assumes the following;

1) Laptop works on AC power — laptop battery doesn’t charge.

2) Laptop battery has worked before in the same laptop

The approach assumes the smart battery system architecture developed by Duracel and Intel. A DELL Latitude D610 business laptop is used as example.

Although the information here might not apply in all cases, it still might shed light on reasons why a HP 381374-001 Battery does not charge.

Diagnosis approach

The diagnosis approach is based on the observation that all laptop battery charging components are active when the laptop is powered off with the AC power adapter connected. This is true for most laptops and eliminates the involvement of the main processor in charging a Dell FP282 Battery .

Laptop battery charging is managed by a second processor on the laptop motherboard. In this approach the second processor is identified as the POST (Power On Self Test) controller. The controller executes initial test during power-on and manages laptop battery charging. Although this might not apply for all laptops, the observation mentioned earlier still stands.

When the laptop is powered-on information about laptop battery charging can be monitored through either through the BIOS setup screen or for example in Windows or Linux.

The laptop battery charging diagram below shows various components involved in charging a Dell RD859 Battery . The blue and red marked text indicates click-able text and loads pages with more information.

MacBook Woes: Cannot charge or retrieve power from battery

Here is a brief summary: About 6 months ago, the computer battery would shut off at random while running on the battery. The battery connector was loose, as the computer battery‘s battery worked immediately after shutting down. I later fixed the loose connector and the computer battery ran perfectly fine for a few months without random shutdowns. 2 months ago, I was working on the computer battery, plugged in, when I left to go eat. I returned 15 minutes later. I decided I wanted to work somewhere else in the house, so I unplugged the computer battery. The computer battery died immediately, and would not power up without the adapter since then. The battery’s condition is fine, since it worked properly up until this problem occurred. Also, the battery says it’s 60% full. Some notes: I did use the computer battery on a 240v line for a week while I was in China. The MacBook’s power adapter is designed to handle foreign voltages and frequencies. This problem began a couple of weeks after returning. I have reset the PRAM and the SMU. This same problem occurs while in the boot menu, in Mac OS X Leopard, and also Windows XP. Please leave only “smart” comments. System Specs: MacBook Core 2 Duo 1.88 GHz (Late 2006) 1.25 GB Ram (had for 1.5 years) 160 GB WD HD (also had for 1.5 years) COPYRIGHT 2008 musicfreakcc Embedding of this video on other websites is PERMITTED and encouraged You may not re-upload this video to YouTube or anywhere else without my prior approval.

In response to the more powerful of the 3C products, battery technology innovation must also be kept in order to supply this generation of more and more hungry, more power to 3C products. The four most common rechargeable batteries – nickel cadmium, nickel hydrogen, lithium ion and lithium polymer in the end what is the difference? What are the advantages and disadvantages of each? Xiaojiang used in this in trying to find data on the network to analyze the extracts of… Nickel-cadmium batteries (NiCd) Is the oldest one rechargeable battery technology, as early as 1899, was invented. Nickel-cadmium batteries can withstand short-term advantages of a large number of discharge and charge process is endothermic reaction – the latter feature will not allow it to charge batteries quickly cause too much damage. Nickel-cadmium battery voltage is 1.2V, than 1.5V alkaline battery slightly less marked, but because the process of alkaline battery discharge voltage will continue to fall, to usually only when no power 1V, instead of nickel-cadmium batteries provided has been very stable until the voltage 1.2V to date no electricity, so the majority of electronic products using alkaline battery nickel-cadmium batteries can be put in, no problem. Disadvantage of nickel cadmium batteries of the most famous is the so-called “memory effect”, that is, when there are still not run out of battery power to recharge, the battery will “remember” the position, remaining so for a long time after the electricity used, the battery will occur and the same response no electricity (voltage transient lower). Therefore, before charging nickel-cadmium discharge process to go through a period, after the electricity to recharge drained. Most of all nickel-cadmium battery charger with automatic discharge function. Than nickel-cadmium batteries for power storage is small (only about alkaline batteries, 1 / 4), and cadmium are toxic heavy metals, less so recently seen. Most applications have been close to its nickel-metal hydride battery (NiMH) replaced. Nickel-metal hydride battery (NiMH) Nickel-metal hydride batteries and nickel-cadmium battery is about the same technology, but replaced the anode from the cadmium hydride only. Most of its features and nickel-cadmium batteries, but a higher storage capacity, memory effect is relatively less obvious (but actually still exist). Ni-MH battery most of the problems is that it has a high self-discharge rate, which is obviously yes full battery charge, aside Buyong month, the electricity can have lost 30% of the spectrum. In the use of 5 and 7 size batteries application, Ni-MH rechargeable battery is currently the mainstream, but has a higher storage capacity required to seek, or need to do more hours of volume, it is necessary by lithium-ion battery was… Lithium-ion battery (Li-ion) Lithium-ion battery is almost fantastic battery charge capacity, compact, light weight, no memory effect, high voltage, and low self-discharge, it is no wonder the majority of modern see 3C products were obtained using the lithium-ion ( or lithium polymer) battery. But the seemingly perfect lithium-ion battery or a danger exists – the most obvious it has a very high tendency to self-destruct, and so much energy will be squeezed in such a small space, blew up and it is spectacular to be expected the. To avoid the risk of the occurrence of lithium must be added a lot of protective measures, the battery charging too far or is overheating, automatically power off. These additional circuits and institutions, is why there is no III / IV size lithium-ion batteries, laptop batteries and why such a high price reasons. Lithium-ion battery also features a more interesting unknown is whether you have not used it, it will be with the maximum charge capacity battery material oxidation decreased. In general at room temperature, the lithium-ion batteries store electricity will drop about 20% per year, and the higher the temperature, charge full survived, survived down fast. So if your laptop relatively poor heat dissipation, then for a long time to full power at 60 ? c environment lithium battery can lose 40% within three months of the storage of electricity. The following are the recommendations of lithium maintenance: Do not use electric light was charging – lithium batteries do not like to be discharged into the finish, so if you often find themselves the power to use the laptop dry, then it stars a bigger battery for it! Do not charge to full power over – as I said before, the more full battery charge, has power down faster, so keep the 60 to 80% full is the best state. Unfortunately, like in addition to Panasonic’s notebook battery, but to achieve this is not easy. Every thirty normal charge and discharge, it is necessary to a “use dry” discharge – a short time are not afraid of lithium-ion battery itself, a small amount of the charge and discharge, but the previously mentioned circuit protection and may result in miscarriage of justice in the end is the battery There is much power. Discharge to a major power with a dry, and then charge to full saturation should be able to protect the loop “correction” back. Many laptop battery have a software or even in the BIOS, to provide such functionality. Laptop with AC power, pull down the battery – which is the storage of electricity as the previous fall, said the issue. Pull down the battery, at least do not have access to the computer itself, it’s hot. If the battery then thrown into the refrigerator, the better… Battery close up, leaving about 40% of the electricity in it – to leave too much storage capacity will reduce the problem, leaving little damage to the battery. What Nansi Hou ah! Have to buy to buy a new battery – new battery have full power Oh! Lithium-polymer battery (Li-Pol) lithium polymer batteries and lithium ion batteries, like the principle, but with a polymer electrolyte to replace the part. This makes lithium polymer battery can be made into various shapes (a good thing for consumers is not ==), in line with demand to be different. Lithium polymer batteries are also safer than lithium-ion battery to high temperature, impact, but there are still over charge ** when the danger. Maintenance and other principles are the same lithium-ion battery (so would rather use the phone every day, lithium battery charger, do not use photovoltaic and we have to charge.)

Notebook battery charge times

Notebook battery aging is by laptop battery charge times to decide, then how calculative laptop battery charge number? If I keep battery in a notebook, with the occasional battery (if use a 15% such, then plug adapter to notebook batteries, this is not a battery again? Still say the battery every complete one time charge need a certain formula computed, not so: as long as we imagine to battery charger for electricity, even if point to, also calculate one time charge. Below are online generally thought calculation modes:

Battery full charge quantity number:

Basically is in accordance with the battery power into to calculate battery charge times and the degree of ageing, counting the method is as follows:

Generally speaking, when the battery charge starting power is greater than the current full power of 70% (this value different companies have different regulation, generally not by much) when the battery power input current accumulated more than 70% of the full charge of quantity, regard as charge once. For example your battery of this limit value is 70%; Every time you are the battery in 80% of time the charging, then your battery can be read out the number per additional charge, the actual number is four times.

Hypothesis full power for: 3800 mah

Start charging more than 70% of the full amount of power: 38 * 70% = 2660 mah (every time in 80% of the time the charging)

Accumulative total input power: : 3800 * * 4 = 20% 3040mah (3,800 * * 3 = 20% 2280mah)

The actual number of charging for less than 3 2660, so said, “every time in 80% of time the charging, need actual charge opportunity to reach four times is finished once the accumulative total”

Below the starting power of the battery, accumulative total input power = full power – the current power, as charge once.

If you are in the power for 60% of the time the charging, 3800mah – 3800mah * 60% = 1520mah, when the input power reached when deemed 1520mah charge once

The above is not very accurate calculation (because every time could be accurate to 60% only when filling, nor all the time from 60% full of the reoccupy after, perhaps filling to 95% began using), everybody casual about can, need not delve into!

The current full power: because the battery aging, so the battery internal a aging algorithm, will automatically according to the battery usage of automatic updates the current full charge the battery energy, in case the overcharge cause unsafe factors. This algorithm, depending on the battery batches, company, manufacturers different and different. Some battery simply used security chip venders set the default algorithm

Simple Steps To Charge Laptop Battery While In A Car | Battery Technology

If you find yourself with just a dead laptop battery in your car and get access to a battery charger, you are just minutes away on the road again. Whether you are a small wheel on the car charger is known as the trickle charger or a larger unit, you can effectively charge your laptop battery.There are some safety concerns, however. Make sure to check the warnings, the following are the steps:

1. Find Remote Charging Station by Read the instructions for the owner. You can also open the hood to find the charging station.

2. Remove the plastic cover, which are the protection of the negative and positive contributions of the Dell d630 battery. Slide the cover to the side as it is generally flexible. Note to the place of the positive and negative terminals are represented by a minus and a plus sign or.

3. Find the laptop car charger, its cables can reach the battery. Make sure your battery charger, an electric rangeOutlet. Add the extension cable if required.

4. Place the charger the battery terminals and make sure that the red terminal is going to go to the positive terminal of the battery and the black clip to the negative terminal of the battery. If you can not be sure you follow the cables attached back to the charging station terminal and find the positive or negative designation.

5. Plug your charger in the eighth that the selector switch should be turned on.

6. Select the appropriateVoltage and speed. If time permits, select the slower and wait to charge the battery for about two hours. If the charger has a timer, set it.

7. After charging, unplug the charger and unplug the charger cable then start the car.

Responsible cycling means a battery is completely discharged (or drain) of a battery produces electricity, where there is a fee of less than 1% residual capacity. At this point, the power to set the device and the device turns off. Then, after the power is turned off you charge the battery to 100% capacity with a power adapter into an outlet forExample. Regardless of how you charge the battery to initiate the process and represents a fully charged battery is recharged.

I noted above that an electrochemical reaction takes place in the Hp 510 Batteries to replenish the electrons. The effect is a chemical process, electrical energy (electrochemical energy) generated. Lithium is used, among other chemicals, such as a battery anode material due to its high electrochemical potential. In fact, the energy of some lithium cellsfive times larger than an equivalent size lead-acid cell and three times greater than alkaline batteries. Lithium cells often have a starting voltage of 3.0 V. This means, that batteries can be lighter, have lower per-use costs and have higher and more stable voltage profiles.

Charging Lithium can be thought of the introduction of ions or movement of the chemical. To the lithium chemistry (lithium ion, lithium polymer, lithium iron phosphate, etc.) you must haveMinimum voltage to the lithium. Most of the battery cells are charged to 4.2 volts with a relatively safe procedure when about 3.8 volts. Everything that is less than 3.3 volts are not sufficient to move the charge or chemistry. One thing to note here is that an algorithmic measure volts of electricity. So to create the sense current through the battery needs to introduce you current in your battery lithium.

Introduction to current lithium intercalation states. Intercalation is theAccession of a molecule (or molecule group) between two other molecules (or groups). When it comes to charging your battery, you are indeed pushing ions in and comes in solid lithium compounds. These compounds have tiny spaces between the crystallized planes for small ions such as lithium, to himself by a force of electricity. In fact, ionizing the lithium loads the crystal planes to the point where they are forced into a current. The current flow is then channeled back andfurther from the anode to the cathode, and thus an electrical current to power on your device. Also this can be done to 300-500 times. In my next article we will, why look like limited battery charge cycles.
