Question: How to charge a laptop if the power controller flew
Digging in the laptop, poke the power settings and spacked so. That the battery stopped charging. I thought that the case was in charge. I could not check the charging immediately, I checked three days later, the battery charge was ended with this war, and the charging was working. I think that turned off something in the settings. . But how to rally if the laptop is not charging?
P.S.-Please do not thread

Q: The laptop battery is discharged when the power is connected
Hello everyone! There is an old laptop, in general working. But yesterday, nephonyatics were discovered with nutrition: even when the power was connected, the battery is suddenly begins to discharge. It is written in Windows: "connected, charging", but at the same time the battery is discharged!
The patterns have not yet noticed, it works in normal mode and with no means to start discharged with anything. Naturally, charging comes up to 0% and the laptop is simply cut down.
The laptop for its time is powerful, even now is used for designer work, throw out a pity, to sell in such a state is also difficult. I sin on the power supply. Who has any ideas, what can it be?
Question: When connecting add. Nutrition to the mat. Place - Rebut.
I will start from the very beginning. Turned off the computer, went to sleep. I wake up in the morning, and the computer SCM turns on for a second, turns the cooler, blinks the LED on the mat. Place - and reboots. And after a second three again. An experimental way found out that if you disconnect additional meals from the motherboard, then the computer is not rebuilding, but normally (as far as I can judge, since I turned off the video card, hard and so on) loaded, does not rebound. Visually with the motherboard everything is OK. What advise you to check, check? From instruments only screwdriver yes soldering iron

So KZ on processor chains. Check (norp) nutrition systems and microhu controls them. If one of the transistors is replaced. It is also possible to the Conder sang.
Question: ASUS X550VC Laptop does not start until you connect the power
Forum users Good day!
Today I stopped turning on the ASUS X550VC laptop until you connect it to the power supply.
As happened - in the morning included it from the battery, worked for about 20 minutes. Moreover, when charging, about 30% connected to the power supply and continued to use for about 5 hours without special loads, only the Internet surfing and installing and deleting, for the sake of the test of one program (ANSYS 15).
After everything, as usual, completed the work and at about 5 hours I tried to start it again from the battery ...
The laptop simply does not start, nor how it does not respond to the power button, but if you connect to it paul The power cord The laptop is turned on as usual and loads the OS works as always.
If after starting in the operation mode, pull the power cord just goes out-off.
During work from the network, the battery charge shows 81% with the mark "charging" and in 2-3 hours from 81% and did not move ...
Shoots, foul, replacing something was not, worked well, used carefully.
Laptop 2 years and 4 days.
Windows 7 64bit, percent. I5-3230M, NVIDIA GeForce 720m video, 4GB RAM, HDD 500GB.
By observation, the power socket is slightly loosened (maybe from time), but everything is inserted tightly.
Still if you connect the power cord but not taken into the network 220 The charging indicator lights up (orange color), then if you press the inclusion button as it is trying to start on the floor, but immediately cuts out and goes out with the orange indicator.
What to think I do not know like the battery worked as always, tried to give to work cleaned - charged to full.
Maybe someone had a similar one?
Thank you all for the help!
Answer: Perhaps diagnostics:
PowerCfg.exe -Energy.
Battery: Last Full Charging (%)
During the last complete charge, the battery was charged less than 50% of the calculated capacity.
ASUSTEKX550A30 Battery Code
Calculation capacity 44250.
Last Full Charging 18345
Last Full Charging (%) 41
Is that talking about the failure of the battery?
There was no comments on the work in the work, it is surprising that when you fail to fail at 100% ...
In most cases, he watched a long and slow process.
The full report attached.
Question: Laptop is not charging
Good day. There was a problem with charging a laptop - if you connect the power, then 2 light bulbs almost immediately flash, either begins to light up and go to the charge light bulb (as if bad contacts and the connection is lost, it appears again) either not charged at all (just lit one light bulb responsible for the laptop). I tried to pull the battery and work on only meals from the network, worked about half an hour - then turned off. Included again, went into the game - turned off after 10 minutes. Also noticed if the light bulb and the power would flash, and then pull out the plug from the network, then the light bulbs continue to flash until the plug of the nest is reserved. Also, if you completely disable charging from the power supply and give to lie down in a non-working state for a while, then when connected, for some time it charges normally, but then it still ceases. It also happens that it charges fine, then the contact is lost (only one light is on), then again finds contact. Already somehow it was, I could not charge a laptop for several days, but then everything went by itself. Laptop itself - Acer Aspire E5-571G-52Q4. What can you advise? Thank you.
This time he was attributed to the same service center. According to the results of their diagnosis:
According to the manager, the cooler breakdown is associated with the incorrect operation of the power controller on the board, which is why the controller gives the voltage jumps and the cooler works "to wear", also want to replace the cooler and lubricate everything.
Tell me, please, as far as it makes sense to replace / repair this "controller", because only for it with me although it is 4,600 rubles, in addition to 2200 rubles for work and 800 rubles. For cooler.
It seems to me that the controller does not affect the controller here and sufficiently replacing the thermal paste, cleaning and replacing the cooler.
Would be very grateful for your opinion!
Answer: If the fan turns changed depending on the temperature, the controller and the fan worked, but the fan grinding speaks about its wear, it is necessary to change it, they have already been changing it, if you do not agree, look for another service.
Q: Laptop does not switch to battery powered
ASUS X550L laptop, 1.5 years old.
As it turned on without a connected BP, I made my affairs and turned off. After a couple of hours, I discovered that without BP does not work. The battery sees, it writes that 92% is charged, it is charged, but nothing happens. The BP is not even turning on. All the power goes with the power supply, the battery does not use it apparently. You can do something in "home conditions" yet SC.
Previously, there was still a problem when you take a laptop in your hands and he switched to sleep mode.
Answer: Everything itself as it has renewed, everything works, but I think it will not be superfluous in the SC. Lives the laptop or fixes to visit his life.
We will not spend a lot of words to say how important and how much the modern laptop is needed. Without him, not a single day. For work, personal communication, creativity, reading, study - Laptop Universal Assistant. Replacing the DELL laptop charge controller is one of the most serious breakdowns. The difficulty lies in the fact that this chip is located on the motherboard. Gently to peel it, not taped nearby elements, it is very difficult. This requires specialized equipment - an infrared soldering station, which is equipped with a service center No. 1. Consider below the items on the topic:
- Causes of breakage;
- Replacement process;
- Warranty.
Causes of breakdown
How to understand that the Dell laptop needs to replace the charge controller device? Let's start with the fact that the mentioned chip controls the flow of current to all parts and compensates for the difference of energy flows on the network, is responsible for the charging process and battery discharge. Sudden disconnection of electricity, stress interruptions primarily sound on the controller. In his competence - with the help of a thermal sensor to regulate the temperature and pressure in the laptop - so that it does not overheat, did not freeze in the cold, to prevent leakage of gases and explosions.
If the device does not see the battery, but the charging goes, or if it does not turn on for a long time, lights up for a few seconds, and then it turns off again - these are the signals that the DELL laptop charge controller is required. Another symptom - if the device is very hot and turns off itself, it is impossible to charge the battery - does not increase the level of charge, regardless of the recharge time.
Replacement process
The failure of the controller actually means that the block of rechargeable elements (directly the battery) needs to be changed. And in some cases, if the power board is also buried or the other chip, the motherboard will have to change. There are cases if the long-time laptop works with faulty components, then the "non-return point" occurs for the device, i.e. It breaks finally and the restoration is no longer subject to. In order not to bring the laptop to such a state, it is recommended to see the change in the distinguity element as soon as possible.
Replacing the controller itself is carried out as follows. First, the service center engineer disassembles a portable computer. It processes a piece of flux (gel that removes the oxide film and helps the effects of liquid solder), adjusts the IR soldering station and substitutes a motherboard with a distinguished component. After the required time of exposure, it dismails it and shakes a new serviceable spare part. After the master removes the remnants of the solder and collects a laptop.
Warranty
For the prophylaxis of a good job of the device, the service center recommends charging the battery only after its full discharge and use the power supply, which holds back voltage downloads than prevents damage from them. After replacing the DELL laptop charge controller, the engineer is mandatory testing the design. And only making sure the device is returned to the user with uninterrupted operation. SC makes a guarantee up to 3 years on this type of repair, provides free diagnostics and delivery "from door to door".
If suddenly, including your laptop to the network, you noticed that the battery did not start charging, do not panic. You are not the only one who encounters this kind of problem, and it is completely solved. For a start, let's see what can be the main causes of this problem. To do this, we will gradually move it the network outlet, where the laptop is connected, to its power supply.
So, probable reasons.
- It is possible that there is simply no voltage in the power grid.
- Fault of the power adapter that converts the current coming to the battery.
- In any place, the integrity of the cord is broken, simply speaking, he will interrupt.
- The fault lies in the cord plug or the nest of the laptop.
- Perhaps the battery driver works with failures.
- Software malfunctions in the bios of the laptop itself.
- The power controller stopped working.
- Reducing the performance characteristics of the battery.
- The use of the battery has exhausted.
Solving problems with laptop batteries at home
Now consider each of the agreed points and will try to determine where the malfunction and, if it turns out, eliminate it. First you can try the easiest way to start the hardware reset of the entire device. To do this, you need to turn off all additional devices from the laptop: mouse, printer, cardreader and everything else. Then disconnect the power cord and pull out the battery. The next step is to hold the laptop switching button and keep it sandwiched for one minute. Then you need to let it go and press two or three times. Thanks to this procedure, all residual voltage from all components of the laptop will be maximally. After that, it is desirable to wipe contact with alcohol on the battery and the laptop itself, which they come into contact. Then we insert the battery into place and turn on the network, while all other devices must be disabled and turn on the computer. Usually such a procedure helps to resolve this problem in half cases.
If the battery did not start charging, we might on the above items.
There is no voltage in the network
Everything is clear with that. Try turning on the power to another outlet and look at the result.
Fault in block
The easiest option to find out is to check the voltage at the output of the adapter itself using the tester. If you currently do not have a special tester, but there is another similar laptop, just try changing temporary power supplies and look at the result. It is worth noting here that if the charger indicator is lit, it still does not testify 100% of its correct operation. If the reason is still in the adapter, then two options are obvious: buy new or try to repair this. If you are a regular ordinary user, you will soon fit the second option.
Damaged cord
You can check the same as in paragraph 2 using the tester or the replacement of the cord on the other. If it turns out that it is in him the problem - just buy a new cord.
Malfunction Note Laptop either power plug
In general, the test is the same as in previous items, and in addition, you should add here to the external inspection of the nest for damage, as well as a little move the plug in the nest. If you have noticed a malfunction in the power connector during the inspection - carry it into a service center, and do not attempt to solder yourself if you are not a specialist.
Incorrect battery driver operation
Externally, it is impossible to note the signs of incorrect operation of the driver, except that the charging indicator will not burn. However, this problem can be tried to eliminate yourself. The best way is to download a special DRIVERPACK Solution utility from the Internet, which herself will check all the drivers, if necessary, update all obsolete and reinstalls non-working. One minus of this program is a large volume, so you can use more "light" counterparts. However, it is worth being attentive, because many of them are paid, and some can even be infected with the virus. Finally, to the description of this item, it should be noted that the problems of the battery driver meet quite rarely, and you are unlikely to ever encounter such a problem.
BIOS software failure
This problem is in the category of very delicate, since you can seriously harm your laptop, trying to solve it yourself. If your BIOS fails, you will most likely fail to include a computer, and one of the signs of incorrect work can be a reset of system time. The cause of the failure in most cases is incorrect setting or updating the bios firmware. Along with this, the possibility of viral attacks, which are directed specifically on the BIOS computer, cannot be excluded. If the problem is in this - carry a laptop to the nearest service center.
Breakage of the power controller
This failure, in the maximum manifestation can manifest itself a complete lack of any indication on the laptop. If this happened - again, give it to the service. In the minimum, this failure can manifest itself so: if you turn off the power adapter for a minute, and then connect again, the battery charging will not happen. For the same so that it starts, you will need to pull the adapter plug from the nest on the laptop for 10-20 seconds, then connect it again. After that, the charging will go as it should. This problem is not critical, and with it, in general, then you can put up if you do not want to give a laptop to the service.
Deterioration of battery performance
A sign that the battery performance fell, there may be short-term laptop operation from battery battery in autonomous power. The time of its autonomous work can strive for zero. To somehow improve these parameters, you need to do the following: When the computer is enabled, go to the autonomous power mode, that is, pull the adapter cord from the laptop socket. It will begin in every way to signal you about the low battery level, but you just do not pay attention and wait for the system's autopulioance. After that, let him lie idle several hours. After that, connect the external power adapter and wait for the battery fully charged, while watching the light charge indicators. This procedure is called "Battery Training". It is recommended to hold it three or four times in a row, and it is also worth performing it every two or three months as prevention.
Exhausted battery life
There is already nothing to go to the service center, since the repair is useless here. You need to buy a new battery. There are, of course, some ways of resuscitation of the battery described on the Internet. However, you yourself can imagine how high-quality will be his subsequent work.
If you still decide that time to buy a new battery, some recommendations will be described below how to choose it. Your choice depends on the three components that are defining for purchase.
1st component - price. With all the desire to buy a battery cheaper, think first, weigh what you get for your money.
2nd component - Battery capacity. The higher the battery capacity, naturally, and above the price, but the longer your laptop can work autonomously.
3rd component - quality. Again, the better than the battery - the higher it will be its resource and, accordingly, its value.
Thus, it is clear that you need to find a compromise between the cost of a new battery and its quality. Moreover, as for quality, the purchase of the battery today is a kind of lottery. For example, you can buy a Chinese cheap battery that will serve you much longer than brand names, since, perhaps, branded and nameless nutritional elements can be collected in the same shops on the same production lines from saved parts.
As for the capacity, everything is clear - it is indicated on every battery, and you can easily estimate, for what time of autonomous work it should be enough.
What the prices swing, then it is worth telling here in more detail. New batteries are approximately the same in different sellers. However, sometimes copies sometimes come across, the prices of which are above a couple of times, and this is explained by these "exclusivity". Do not come to such tricks, and buy a normal battery at the appropriate price from ordinary sellers. Having received a list of sites in the online search engine that sell batteries for your laptop model, try to find out more about sellers, read the reviews on the forums.
Also worth walking on the shops of your city, shopping computer components, compare prices. Do not hurry with the purchase, first all analyze and calmly accept the decision that and where to buy.
The replacement of the charge controller of the ACER tablet is carried out under the following conditions that guarantee the operation of the device. The tablet is replaced with a modern person a lot of things - they write down the diverse necessary information - from schedule for a day to PIN codes and passwords. Therefore, the service of urgent repair of the tablet is popular. The cost of the work and the timing of the repair operation are determined on the day of visiting the service center. Accessories Replacement Stages:
- Diagnostics of acer tablet;
- Disassembly;
- Replacement process;
- Warranty.
Diagnostics of the tablet Acer.
The charge controller is a microcircuit that is integrated into the motherboard. It is responsible for the charge cycles and the device discharge. In fact, it is precisely from it that the battery life and the amount of energy that it can take is depends. The spare part requires a careful relationship.
The problem with the nutrition chip occurs less frequently than the failure of the battery or power connector. Therefore, to establish the exact cause of the breakdown, the ACER tablet is diagnosed. This procedure indicates the state of the hardware and sets the presence of hidden defects.
Failures in the "feeding chip" are fraught with battery breakdown. The battery is designed for a limited number of full discharge / charging cycles, after the exhaustion of which the possibility of energy accumulation is gradually dried. The controller, if incorrect work, knocks off the battery settings and displays the device.
Disassembly
Since the charge controller is integrated into the motherboard, to replace the charge controller on the ACER tablet, you must open access to the module. To do this, the engineer removes the back cover of the tablet, removes the battery and dismails the fastening bolts and the case. Then it is retrieved by modules adjacent to the housing. In some Acer models, the motherboard is directly available, and in others it is necessary to carry out a deeper analysis.
Replacement process
Manipulation is implemented by soldering elements. Due to the small size of the component and proximity of the integrated elements on the motherboard, the engineer must have "surgical accuracy". In this he helps the infrared soldering station - it automates the process of soldering, excluding errors. The old, failed controller fears, and then (with the observance of the specific temperature mode of the surrounding modules) a new one, which fits the repaired model of the tablet computer.
Warranty
Replacing the Acer Tablet Controller is a subtle operation, specific equipment and experience of the engineer are needed. The service center works only with original details suitable for this tablet model. Therefore, a long warranty is provided - up to 3 years. After repair, the test turning on the Acer table is implemented in the presence of the user.
