Who will fix a laptop battery? There are big rewards

If you trust the professionals, read on, otherwise delete the following.

The phenomenon seen by the landlord is because the battery life is long and the battery life is reduced. Replacing the battery cell can indeed solve this problem, but not everyone can. This requires professional equipment and professional technicians. The problem to be solved first, why disassemble it, and then weld it back and not turn it on?

Answer: The battery protection PCBA has a CPU, which we call GAS GaugeWhen you remove P+, the IC enters shut down mode.

When you solder back, the IC is still in this mode, and there must be a wake up voltage from the external power supply to make it move from shut down mode to normal and sleep mode. At this time, it can communicate with the laptop CPU and be recognized. You can't change it yourself, you can't do it with the wake up step alone.

Yours is 4s2p, wake up voltage, current is about 10mA. What's more, the replacement of the wire inside, the tweezers copper bus (refers to the copper sheet connected to the single battery cell), which is spot welded. Of course, this also means that no other parts are harmed.

My suggestion is:

Merchants replacing battery cells are all deceptive. It's all for you second-hand. Even if it's new, it's not much the same price as if you were buying a new one. So it is recommended that you go to ** and buy a cheap second-hand one directly, or you can buy a new one directly. (if the official website still has one).

Laptop batteries generally do not advocate their own disassembly and maintenance, after the laptop battery is disassembled, there are greater safety hazards, and now the battery is not expensive, just change one!

Well, it's very troublesome for the landlord to change the battery. Don't do that, it won't cost you much to buy a new one. Changing the battery cells is all to amuse you...

1. The laptop battery is damaged and cannot be repaired, only a new battery.

2. The life of the laptop battery is based on 800 times of electricity, and the battery can no longer be used after 800 times of charging and discharging. Sometimes, although it does not go through so many charging and discharging processes, it is also because the battery is permanently placed on the computer, which will reduce the battery life. This is a reduction in life caused by improper use.

3. If the laptop battery cannot be charged, or it runs out soon after charging, the battery has reached its life and should be scrapped. Because the combined parts of the battery cannot be replaced, there is no repair value.

1. Generally, notebook batteries use or, and a single battery cannot meet the requirements, so laptop batteries are battery packs composed of multiple single batteries connected in series and parallel. As for the 3300mAh, 4400mAh, etc. that we often see in the shell of the battery, it refers to the capacity of the battery, which indicates that the current can be used for one hour when discharging the battery, for example: a 4400mAh lithium battery can be discharged at a current of 4400mA for one hour.

So the higher the number, the better it will be to prove that it will work for a longer period of time.

2. The charge and discharge control and protection circuit is responsible for the charge and discharge control and protection of the battery as the name suggests, and the principle of its work is as follows, because the voltage of the lithium battery will drop slightly when it is very close to being filled during the charging process, so when the control circuit detects this situation, it thinks that the battery has been filled, and the protection circuit also works to cut off the power supply to prevent overcharge; When the control circuit detects this situation, it considers that the battery is out of power and notifies the protection circuit to cut off the power supply to prevent the battery life from being shortened due to excessive discharge.

3. When replacing the battery pack by yourself, you must have a little physical knowledge and be bold and careful, that is, you must dare to disassemble the battery, and be careful not to damage the circuit part when you do it, otherwise you will not be able to buy a new one. In fact, this is also very simple, after disassembling the shell of the battery, you can see the internal battery pack and circuit, then you carefully observe the series, parallel party and battery type, model and number of batteries used in your battery pack, and then go to the electrical market to buy back the battery cells required for the battery pack.

4. When buying battery cells, it is necessary to pay attention to the fact that you must buy products of the same brand, the same model and the same batch, because the experiment shows that when multiple batteries are used in series and in parallel, due to the subtle differences of the battery cells, a battery cell will fail in advance and affect the work of the entire battery pack, so you must pay attention. After the battery is bought, of course, it is necessary to solder the old battery from the battery pack one by one with an electric soldering iron, and then solder the new one back as it is, but it should be reminded that the temperature of the electric soldering iron should be higher, so that the soldering process can be in contact with the battery in a short time, otherwise the battery life will be shortened and the performance will be reduced due to the high temperature. Finally, seal the shell with 502 or other glue, put it back on the notebook and test it, if it's okay, then congratulations and you're done!

I believe that most young people have a beautiful laptop in their hands! However, when the laptop is used for a certain period of time, there will be more or less problems. So what to do if your laptop battery is broken?

1. How much does it cost to repair a laptop?

1. First of all, when you find that there are some small problems with your laptop, you must not be too anxious, so as not to mess up. Finding a suitable repair site is your current job. But you need to pay attention to:

There are many places to repair laptops, so only the pants shop that is selected according to the reputation of consumers is the most suitable.

2. Then, according to the survey, if there is a problem with the main card or graphics card circuit of your laptop, then its maintenance cost is generally between 200 yuan and 300 yuan. If it is a memory problem, then its repair cost is generally between tens of yuan and hundreds of yuan.

3. Finally, since the economic level of each region is very different, the laptop repair cost above is for your reference only. In fact, if you want to know the most real laptop repair cost, you better go to your local repair shop and ask the repairer, or ask some professionals!

2. What should I do if the laptop battery is broken?

1. Use the battery correction function in the notebook BIOS.

You can first turn on your laptop, press F2 to enter the BIOS menu after the interface appears, and then select the Power menu, at this time you can see the "StartBatteryCalibration" option. All you need to do is click and press enter. You'll see your screen color blue and prompt you to plug it in and charge.

When fully charged, it will automatically discharge, but it will take some time. When it's all drained, you just have to charge it again and the battery correction process is complete.

2. Let the laptop power on and discharge naturally.

You can go directly to the "Power Options" interface, set the "Power Usage Scheme" to "Always On", at this time, you should convert "Turn off the monitor" and "Turn off the hard disk" into the shortest time, and at the same time, you must cancel all power options, so that the power of the laptop will run out.

Orange indicates that it is charging, or try to turn on the battery after charging for a few minutes, and the battery is too low to turn on.

The high temperature in the state of full load of notebook performance generally occurs when playing games, and the built-in heat dissipation of some notebooks cannot meet the requirements, and the damage to the battery is very serious after long-term overheating. If it is a business laptop or a thin and light laptop, you should still avoid playing too many games, and you should choose a gaming laptop to play games.

Try not to let the battery run out completely, some batteries have a management chip inside, in order to avoid accidents with the battery, the battery will lock when the battery is depleted. At this point, it's hard to turn it on again.

Laptop battery is just an accessory.,It's a consumable.,As long as you can plug in the power supply.,It doesn't matter if there's a battery or not.,You say it's broken again.,It means that you've been using this book for several years.,If you don't need to carry it around.,Mobile office,You don't need a battery.,Just plug in the power supply.。

The laptop battery is broken, replacing a new battery will work fine, if it is a circuit problem, it needs to be repaired.

If there is still a problem with the newly replaced battery, it is recommended to take it to the place where it was purchased for testing and repair.
