The battery in Dyson vacuum cleaners must be decoded before it can be used properly. This is because Dyson vacuum cleaners use cordless technology rather than wired technology. The radio must be decoded before it can find the signal, otherwise it will not work properly.
Before using the Dyson vacuum cleaner, you must disconnect the battery and then press the switch button. At this time, the engine will start to run. When the motor reaches a certain speed, press the switch key and the motor will stop working. At this time, the dust will be sucked into the filter of the vacuum cleaner through the suction of the vacuum cleaner.
When dust is sucked into the filter, you must press the reset button to empty the filter before you can use it again. The reset button is usually located on the front of the vacuum cleaner, with a triangular shaped button.e above.
It should be noted that the Dyson vacuum cleaner battery can only be used once. When the battery runs out, it should be replaced with a new one. If the battery is not replaced in time, the vacuum cleaner will not work properly.
Question 1: How to restore a locked laptop battery? There are several situations in which laptop batteries can freeze:
1. The battery freezes due to over-discharge. To prevent permanent damage to laptop batteries caused by overcharging or overdischarging, laptop batteries are equipped with protective plates. When the laptop is not used for a long time, the battery's self-discharge behavior will cause the battery voltage to continuously decrease. When it decreases to a certain level, the action of vThe protection plate lock is activated to prevent the battery from deforming. continue to discharge.
Solution: Connect the positive and negative poles of a power supply with DC 12V output to the positive and negative poles of the battery, perform direct charging, stop charging when the battery voltage reaches above of 11.1V and put the battery back into the laptop. Connect the power adapter and check if the battery returns to normal.
2. The power management chip is locked. When replacing the laptop battery (strictly speaking, replacing the battery core) or other operations, the power management chip will lose power and cause it to crash.
Solution: Depending on the management chip model, use special software and programmer to rewrite the chip.
3. False lockup caused by component failure. EDue to damage to the MOS tube and other components of the battery protection board, the battery cannot be charged normally, which is basically the same phenomenon as battery blocking.
Solution: When the power is turned off, use the resistance range of a multimeter to detect the protection board components and replace the damaged components.

Question 3: What to do if the laptop battery is locked? There are three possibilities for the battery to be locked:
1. The battery charging protection circuit fails, overcharges and exceeds the protection voltage of the battery chip, the charging chip the battery will directly disconnect the battery core and refuse to output
2. The battery temperature is too high. detects that the battery temperature is too high, the fuse program will be started and the battery output will be disconnected.
3. Diceexcessive battery charge. The battery itself has a self-discharge process. This usually takes around 3 months. Once the battery cell voltage falls below the protection voltage set by the chip, the battery cell stops working.
p>
Auto battery lock cannot be repaired via software. be repaired by resetting the hardware. The solution is:
1. Use a multimeter or BatteryMon_v2.0 software to measure the battery voltage. Generally, laptop batteries are composed of 3 groups or four groups of 3.7 V. ~4.2 V batteries are connected in series. Taking three groups as an example: voltages below 3.7*3 = 11.1V belong to low voltage protection. The battery can be charged directly by the laptop's power adapter. When the charge recovery voltage of thebattery exceeds 11.1 V, put it back into the laptop and charge it.
2. If the voltage cannot be measured with a multimeter, it is recommended to find a battery repairer on Taobao to repair and replace the battery core.
3. If the battery voltage is too high (above 4.2*3 = 12.6V), you can find a 12V CPU fan and discharge it with a low current until until it is within the normal range. But basically if it is too high, the voltage may not be measured!
Question 4: What should I do if my laptop battery is locked? Please follow these steps:
Turn off the computer and remove the battery < /p>
Connect The power is on normally, check if the system displays the Battery Detected
Shut down As normal, connect the battery and check if the latch is closed.
Do not connect the power orDo not turn it on normally. Check if the system indicates that the Battery is not detected. If discharged immediately, it will automatically turn off the computer and not turn it back on. It can be used normally after 30 minutes of charging.
5. If you continue. can't solve the problem, please continue to ask questions
Question 5: Unlocking Laptop Battery 1. Preparation: A locked laptop battery , a multimeter, a 0-30 V meter (you can use a multimeter), a lithium battery charger and a 50 cm wire.
2. Open the locked battery of the laptop and use a multimeter to measure whether the positive and negative terminals of the battery are 12V (10V-12V, if there is no has no 12V, use a charger to charge all three). battery chains respectively.
3. Find the positive and negative poles of the interface de laptop battery output locked. (Usually they are on the far left and right. The negative electrode and the negative electrode of the battery are connected. Use a multimeter to measure it. If the electrode is on the far left, the electrode positive electrode is on the far right The negative electrode is on the far right and the positive electrode is on the left )
4. Connect the 0-30 V voltmeter (multimeter) to the positive poles. and negatives of the laptop battery locked output interface. . Connect one end of the wire to the positive end of the battery and click (a few more times) to lock the positive end of the laptop battery output interface.
Question 6: The computer battery release lock is locked. How to solve it? Mine is: two loops left and right
Question 7: Is the battery safeused? The battery itself has a circuit to protect the battery.
When the battery is fully charged and the charger continues to work, there is a certain probability that this will cause an "overcharge" and the battery will be locked for protection reasons.
It can be unlocked by draining excess electricity...
Well, there are other ways. Some lithium batteries automatically lose power under natural conditions for a period of time and can automatically restore themselves...
You can do this, put the battery into the machine, then plug it in. After turning on the machine, if there is a sleep function, keep waiting, then unplug the power. The problem may be resolved after a few hours (or more than ten hours)...
Question 8: The laptop battery is locked. What does it mean that the computer batteryThe portable device will be locked if it is not used for a long time, cannot be used or cannot be charged. Can it be opened if the battery is locked? Laptop batteries will automatically discharge even if they are not in use. So even if a fully charged battery remains unused for a long time, this situation will occur to prevent the battery from continuing to discharge when its power is too low. , causing permanent damage to the battery, the battery protection chip will be locked, causing the laptop to fail to recognize the battery, unable to charge and discharge, etc. When the voltage of the lithium battery is too low, the performance of the battery will be seriously damaged, and the lithium battery will automatically discharge [the voltage will gradually decrease over time], so that the computer batteryOur laptop has a monitoring chip. Once it detects that the voltage is too low, it will be written to an eeprom, causing the battery to be unable to output. This is called self-locking. The so-called unlocking involves updating the eeprom settings in order to open the output line [also the load input], which can be restored by replacing the circuit board. However, the battery has a lifespan and the official did not disclose all the details of the monitoring chip. The laptop battery protection board is a circuit board based on the SMB1.1 protocol and has power management and charge and discharge management functions. The protection board is a printed circuit board based on the SMB1.1 protocol. It has three chips, namely: a battery measurement management chip, a charge and discharge management chip and aserial EEPROM memory. Laptop battery protection board. The front of the protection board is equipped with a laptop battery measurement management chip and a charge and discharge management chip. The back of the laptop battery protection board is equipped with a serial EEPROM memory chip to decrypt and unlock the laptop. The battery protection panel is two different tasks. To put it simply, you can only access the battery management system by decrypting it first, and you can only change the battery settings and usage information by unlocking the battery management system. battery.
Question 9: What should I do if the laptop battery locks up after being over-discharged? It can only be discarded over time, extra points, or frequent charges and discharges.uents. , will have a great impact on the damage of the laptop battery.
