Replacement Battery

I believe that many users have the same feeling: after using the laptop for a long time, the hottest place is not the surface of the fuselage, or even near the outlet, but next to the notebook power adapter, pick it up, there is often a feeling of hot indeed worrying , it will suddenly one day strike, or a whistle, smoke and other faults.
Notebook adapter is a high-precision, high-efficiency switching Asus EXA0904YH Adapter, its role is to 220V AC power is converted to low voltage DC to provide stable power to the laptop to work properly, it has even been called a notebook of power source “.
Inside the Dell XPS 15 L501X Adapter is a switching power supply high voltage, high current state, the workload is heavy, and is fully enclosed structure, no cooling holes on the shell, the internal fan assisted cooling, and thus the Asus ADP-150NB D Adapter at work The internal temperature is high. Especially in the hot summer, touching the surface can feel hot to the touch, the internal temperature is even higher. Thus, in the day-to-day office, entertainment to it the proper care and maintenance.
Step / methods
To create a favorable thermal environment. Using a laptop in a high temperature environment, the power adapter should be placed away from direct sunlight and airy place; Dell Inspiron Mini 10 Adapter on the laptop near the cooling air outlet, otherwise not only the heat of the Dell PA-15 Laptop AC Adapter does not go out, To absorb some of the heat.
In the hot summer, we can put the adapter side, in order to increase the contact area of ??the adapter with the air, so that the adapter better dissipate heat. In order to obtain a better cooling effect, we can pad between the Dell PA-21 Adapter and desktop into a narrow block of plastic or metal block, around the adapter to increase the air flow speed, speed up the adapter’s heat.
The exception occurs should be promptly discontinued. Even smoke, is often damaged or malfunction should stop use immediately be put into use again after overhaul by a professional engineer in the Dell Alienware M11X R3 laptop AC adapter to a larger issue of noise at work.
The use of non-genuine power to be cautious. Non-original power adapter in the output interface, voltage and current values ??may exist some differences in nominal (or is not), if the mismatch, it may affect the stability of the notebook running even more serious consequences. In addition, different models of the same brand Dell XPS M2010 Laptop AC Adapter when switching to should also be careful, we later described in detail.

A power cord, or AC adapter, charges a Toshiba laptop battery and powers the laptop. If the battery is not charging while the laptop is plugged into the AC adapter, it is likely that you need to replace either the toshiba laptop ac adapter or the battery. You can easily test both to determine which is the cause of the problems. Once you have identified the cause, you need to replace the faulty part.

1.Power down the Toshiba laptop. Remove the charger for Toshiba PA3468E-1ACA and any other power sources.

2.Slide the battery release mechanism, located on the bottom of a Toshiba laptop, to the right. Continue holding the release mechanism in place while sliding the battery out of the battery bay.

3.Install the AC adapter into the outlet on the right side of the Toshiba laptop. Plug the PA3516C-1AC3 adapter into an electrical outlet that is working. Power on the laptop. This process troubleshoots the Toshiba PA3467E-1AC3 adapter. If the laptop turns on, the AC adapter is properly functioning. If it does not, replace the AC adapter. Once replaced, the new AC adapter should charge the battery. If it does not, continue troubleshooting the battery.

4.Turn the Toshiba laptop off. Remove the AC adapter.

5.Clean the Toshiba battery contacts by dipping a cotton swab in isopropyl alcohol. Rub the cotton swab on the battery and battery bay contacts to remove dust and buildup. While cleaning the contacts, inspect them. If you note corrosion, dings or dents on the battery, replace the battery. Do not use a damaged battery in a laptop as it can cause damage or start a fire.

6.Line up the Toshiba battery contacts with the laptop battery bay contacts. Push the battery downward until it snaps and locks into place.

7.Insert the AC adapter. Charge the battery for eight hours. During this time, do not turn on the laptop or remove the AC adapter.

8.Remove the AC adapter. Turn the Toshiba laptop on. Replace the battery with a

Laptop battery a long time, it is often sufficient dissatisfaction, or even show damage, it is necessary to pay attention to some tips when using: Regardless of your notebook uses lithium or NiMH, as far as possible the basic to power after the exhaustion of power (capacity less than 5%), this is the best way to avoid the memory effect. In fact, lithium-ion batteries also have a certain memory effect, but much smaller than the nickel-hydrogen batteries only. But note that charging the battery, try to avoid too long, the general control within 12 hours.

The Dell XPS 15 Battery battery life varies not by the total use of time, but by the charge and discharge times to decide. If the battery is always attached to the notebook and not taken down, even if you turn off the machine and remove the AC power, the battery will not like the thought kept as fully charged state. Laptop battery battery in the integrated control circuit, so even if also turn the computer off when power. As one connected to AC power, the battery will start charging whenever the power is turned on or off, the battery will repeatedly charge and discharge, affect battery life.

For this reason, when using Dell Inspiron 1545 Charger the AC external power supply is best to unplug the battery, or the battery for a long time in the heat affect their life. If the battery is not being used for a long period, at least two months in charge and discharge time, to ensure that its activity. In the custody of the battery when there are problems that need attention. At present, the vast majority of notebooks used in lithium-ion battery for long periods of time, often prone to the phenomenon of excessive discharge, may no longer be able to charge. In order to prevent excessive discharge, charge state in half stored in a cool, dry place, and then once every six months, and then its electricity to half of the state.

In addition, the factors that affect battery life including the use of environmental temperature (below 30 ° C is recommended to use), battery storage and battery temperature suffered shock size. Battery will be in use for some time after aging, the specific expression of the resistance, in charge when both ends of voltage rise faster, so it is easy to charge control circuit is judged to have been filled, the capacity of natural decline in . Toshiba PA3905U-1BRS Battery Battery calibration is an effective way to deal with aging batteries, the few notebook will have a dedicated battery calibration software. If your laptop does not have a dedicated discharge software, you can follow the steps below:
1.The screen saver is disabled;
2.In the Windows Power Management power scheme is set to “always open”;
3.Alarms tab will be “low battery alarm” is set to 10%, the operation is set to “no operation”;
4.”a serious power shortage alert,” set to 3%, operating as “waiting”;
5.The screen brightness set to maximum;
7.Confirm Close all the windows, and save all the data before the work;
8.Sure that the battery is charging more than 80%, unplug the power and all external devices.

After discharge, the notebook will automatically shut down after the power plug for laptop charging, this process can be repeated 2 to 3 times, the purpose is to let the battery current discharge, which discharge state in our daily use is impossible to achieve , the effect of those dedicated discharge software is basically the same.

Review:

“Good price and new item. It was delivered fast. I would order again. Make sure you get the OEM part as others do not recharge your battery. ”

“My original charger refused to charge my computer so I ordered this one as a replacement dell inspiron 1545 charger. As soon as I connected it my computer was able to charge and I didn’t have to overspend to fix a simple issue. Very satisfied with purchase.

One main advantage of using a laptop computer — as opposed to a desktop computer — is that you can use it anywhere, provided that you have an adequate power source This power source may be a fully-charged battery or an outlet for your toshiba AC adapter. If you’ve plugged your computer into an outlet, but notice it isn’t charging, or if your computer shuts itself down while it’s plugged in, you may have a faulty AC adapter.

1 Plug your Toshiba PA3716a-1AC3 AC adapter into a different outlet and see if your laptop charges. If your laptop fails to charge when plugged in, a faulty power outlet rather than the adapter itself is likely to blame.

2 Remove the battery from your laptop and attempt to use the computer with the PA3716a-1AC3 adapter plugged in. If your computer still functions, your AC adapter works fine. If your battery won’t charge, the problem is with the battery, not with the AC adapter.

3 Plug your AC adapter into another laptop of the same make and model to see if the computer functions and to see if the battery charges. If the second laptop functions properly, your laptop is likely the root of the problem.

4 Purchase a new toshiba laptop ac adapter and see if your laptop functions properly with it. If your laptop won’t power or stay on, the problem is with the computer itself. If the battery still doesn’t charge, replace your battery.

Power adapter manufacturers need to embrace the new trend

Not long ago, the laptop is limited, such as the power requirement of only 50-70 watts (W). In recent years, power requirements, climbed to more than 100 W range, but the weight and size of the desired no corresponding improvement. In addition, the need to meet the low standby power adapter performance specifications, the harmonic efficiency requirements of the external power supply (EPS) and IEC1000-3-2 for more than 75 W of input power requirements make this challenge even more difficult to deal with. This article explores the recent trend of acer power supply manufacturers can address these challenges, and provide a different alternative solutions to choose from.

With laptops increasingly feature-rich electronic power requirements increase. In addition, because of the increased laptop battery capacity (or density), the charging requirements also increased – so, laptop power adapter for greater doubled. However, for millions around the world carry the laptop user, the larger and / or more thermal power adapter is not too attractive alternative. Can be attractive apple laptop adapter has a lightweight and small, but immediately charged. Of course, it does not produce heat, but does not spend too much. In recent years, the development of electronic products did not increase our hope in this regard, and whether the future of the revolution can be achieved is still an open question. We also want a asus notebook adapter can be used globally, without the need for a 110/220 volt operating voltage selector switch – laptop adapter must be truly universal line voltage work. At the same time, the expectations of regulators and OEM also play a role.

Regulatory agencies notebook adapter for compaq does not waste energy or electricity lines harmonics. The first factor is that the adapter does not insert the plug with no load, it should be as little as possible the absorption of the power (standby requirements). People generally used the laptop adapter for delta is plugged in, but not connected to the computer, the requirements can prevent the loss of this case. The second factor is the recent requirement, it requires specific average power efficiency under different load conditions (25%, 50%, 75% and 100%) by the global specification bodies perform, in order to promote compliance with the specification and reduce overhead costs. Finally, reduce the harmonic requirements enforced by the European Union and Japan have been used in dell laptop power adapter, because they have already exceeded these standards 75 W input power threshold. In a sense, the movement of the laptop adapter / Universal features making it the first mass production of power products IEC1000-3-2 specification.

Existing solutions and existing laptop converter general flyback topology, the pulse width modulation (PWM) converters. It was for many years the most effective solution (in terms of cost and technical). As shown in Figure 1, a typical flyback converter for laptop adapter for fujitsu at universal input voltage range (90-265 V ac), and ON Semiconductor has introduced a highly integrated PWM controller solution , the use of fewer components. If less than 75 W, the power level of the adapter without additional power section. The key performance criteria for these adapters is the power density (package size requirements), safety and low case temperature. The main method of control is to achieve classic UC384x series current mode control. However, as shown in Figure 1, the laptop hp ac adapter with different PWM controller (such as ON Semiconductor, the NCP1200). The new generation PWM controller is better than UC384x is:

The higher level of integration to reduce the number of external components, while still retaining the advantages of current mode control; * be able to enter skip mode to reduce standby and light load losses; * start input high voltage (HV), reduce the start-up circuit loss and component costs; without IC error amplifier circuit, error handling to be completed in the secondary; * easy to comply with safety and EMI, in order to market faster.

However, for more than 75 W power requirements of the hp compaq power adapter, the laptop manufacturers face a choice. Join the power factor correction (PFC) for universal application design adapter and need PFC (Europe and Japan) market segment or separate design. The increased PFC stage to increase the complexity and cost, make the design more challenging. Typical design applications in this application as shown in Figure 2 critical conduction mode (CRM) boost PFC stage.

CRM PFC design uses the MC33262 controller, as shown in Figure 2. This simple 8-pin controller can easily achieve liteon laptop power factor correction. In critical conduction mode, you can achieve some circuit level advantages, such as non-the diode recovery issues and lower switching losses.

Although manufacturers to adopt this approach has been embodied in the existing design performance and cost acceptable, but still need to be improved in order to meet growing emerging requirements.

In the PFC, although the main CRM methods, but there are obvious limitations. First, it is a variable switching frequency mode work in the zero crossing and under light load conditions, and the switching frequency may be increased to high. Variable frequency filter and low standby laptop power for ibm consumption problem. The NCP1601 introduced a new solution, it draws on the best features of the method of the critical mode, while limiting the switching frequency and improved standby performance. In this solution, the controller can seamlessly in discontinuous conduction mode (DCM) and critical conduction mode switch, and will not affect the sony ac adapter factor correction. The line voltage is at or near the zero-crossing and under lighter load conditions, the controller to work real fixed-frequency DCM PFC mode. Full load and near the peak of the waveform of the line, the controller switches to the critical mode, thus limiting the peak current value does not become too high.

In addition, in recent years, PFC implementation available discrete components come a long way. PFC MOSFET requires a rating of 500 volts, and the introduction of low Rds-on and a small gate charge MOSFET have a tremendous help. CRM or DCM boost diode circuit and manufacturers have begun to introduce a variety of components, such as MUR450PF, to cater to these needs require different characteristics.

The final result of these improvements is increased PFC adapter for toshiba design from a cost point of view, not a big burden, while at full load, low line efficiency of about 95% efficiency and <300 mW standby power consumption. These performance obviously adapter designed to meet OEM specification requirements.

Avoid use in outdoor or harsh environments, and to prevent the Lenovo b465 battery is exposure or moisture. When you do not use the Lenovo b465a battery when, Unplug. Long energized let adapter has been in working condition, will affect the ultimate service life. 3 adapters are all broadband working voltage marked from 100V-240V can, but if used in the case of very unstable voltage, it will also cause damage to the Lenovo b465c laptop battery

The adapter failure usually where? Under normal circumstances, the failure of the Lenovo b465g battery is more in line, like the interface at the wires and adapters to connect first class. Easily lead to a power cord because these parts are often bent, broken, or poor contact. Such failure may be renovated, a new line opens for root on OK. The Dell Latitude E6420 AC Adapter now on the market, in fact many are changed his line or renovated, will not affect the result of the restoration of normal use.

How to make a power adapter longevity?

A long time due to the Lenovo ideapad y480 battery does not belong to the vulnerable parts, if the method can be used properly. Below is necessary to say a few precautions:

Adapter are generally marked “restricted to indoor and information products, so you should try to avoid use in outdoor or harsh environments, prevent Dell XPS M1730 AC Adapter exposure or damp. Not only adapter that many electronic products should pay attention to these two points. Because exposure will accelerate the aging of wires, such as Shell, it makes use of the temperature rise. As for moisture, it may lead to an internal short circuit, causing burned.

Unplug when you do not use the Lenovo ideapad y480m battery. Long energized let adapter has been in working condition, affecting life. In addition, at the connection of the Lenovo ideapad y580 battery cord and adapter must be special care, the wire bending angle can not be too dead, so is likely to cause the wires to break. Junction of the adapter should also avoid bending, otherwise it will cause poor contact. The adapters are all broadband working voltage marked 100V — 240V, but if used in the case of unstable voltage, the same damage.

I believe that many users have the same feeling: after prolonged use of laptops, the hottest place than body surface, or even near the outlet, but the notebook power adapter next to pick it up, there is often the feeling of hot, indeed people worry that it will one day suddenly strike, or if there were howling, smoke and other faults. HP Pavilion dv4 AC Adapter is a high-precision, high-efficiency switching HP Pavilion DV7 AC Adapter, 220V AC electricity is converted to low voltage DC to provide stable power for notebook normal work, it can even be called a notebook. ” the source of power. ” Inside the Toshiba PA3715U-1ACA AC Adapter is a switching power supply work in the high-voltage, high-current state, the work load is heavy, and a fully enclosed structure, no cooling holes in the housing, internal fan assisted cooling, and thus Dell Alienware M11X R3 AC Adapter the internal temperature at work are very high. Especially in the hot summer, touching the surface can feel hot, the internal temperature is higher. Thus in the day-to-day office, entertainment, to it the proper care and maintenance.

Create a good thermal environment. Using a laptop in a high temperature environment, should be placed in the Dell Latitude E6320 AC Adapter and airy place away from direct sunlight; near the cooling air outlet Dell Alienware M15x AC Adapter on the laptop, otherwise not only the power adapter The heat does not go out, but also to absorb part of the heat. In the hot summer, we can put the Dell XPS M1730 AC Adapter side, in order to increase the contact area of ??the adapter with air, so that the adapter’s better dissipate heat. In order to obtain a better cooling effect, we can also pad between the adapter and the desktop into a narrow plastic block or piece of metal in order to increase the air convection speed of the adapter around, to speed up the adapter’s heat. The exception occurs shall promptly stop using. Asus ADP-90SB AC Adapter to issue a large noise even smoke, often damaged or malfunction, you should immediately stop using reconditioned by the professional engineer before put into use again. The use of non-original power to be careful. Non-original Asus ADP-150NB D AC Adapter output interface, voltage and current values ??there may be some differences (or nominal and actual discrepancies), if the mismatch, it may affect the stability of the notebook running even more serious consequences . In addition, the different models of the same brand notebook Asus EXA0904YH AC Adapter switching to should be careful, we detail later.

Any power has some internal resistance, so when the Dell PA-4 AC Adapter output current when the internal cause a pressure drop equal to the output current multiplied by the internal resistance of the power. Pressure drop would result in two things, one is to generate heat equal to the output current squared multiplied by the internal resistance, so the Dell PA-21 AC Adapter will be hot, and the other is the output voltage becomes equal to the nominal voltage minus the internal pressure drop, causing the output voltage to reduce. Finished heat problem, the usual design, generally limiting a current value when the output current has reached this value, the output voltage is reduced to 95% of the nominal voltage, or other proportion, the manufacturers can be set according to the different needs of the load products given a higher or lower ratio, the current value is the nominal current. Such as 72W ThinkPad 16V Dell XPS M1730 AC Adapter nominal current is 4.5A (16 × 4.5 = 72). If the load resistance is too low, causing the output current exceeds the nominal current, generally two things will happen, one for the individual components due to heat more than the heat capacity resulted in the burning caused by damage to the Dell PA-15 AC Adapter, and the other is the thermal design left margin only visible The output voltage is further reduced, if reduced too much may cause the load does not work.

Under the premise of guaranteeing quality, we naturally hope that the Dell Alienware M15x AC Adapter is as lightweight as possible, by the above comparison, we can see that the association part of the Dell JU012 AC Adapter has successfully “downsizing”, not only the volume is reduced by many, and weight reduce about 0.24 kg. Acer’s new notebook recently a high degree of concern, In addition to the cost-effective than other books slimmer body is also one of the reasons, but together with the adapter into the bag, their total weight is not more than other books light. It seems that Acer may be considered to redesign its power adapter. Summary: I believe that many users have the same feeling: after prolonged use of laptops, the hottest place than body surface, or even near the outlet, but the notebook Dell Inspiron 1545 AC Adapter next to pick it up, there is often the feeling of hot, indeed worrying, it will suddenly one day strike, or whistle, smoke failure.
