I just bought a Lenovo notebook, the battery is broken, just 3 days , can I ask for a replacement c

Laptop battery use and care:

1. If you use the external power supply for a long time, it is best to remove the battery, which can prolong the service life of the battery. Reason: Due to the different brands, models, and ** of notebook computers, their power circuit design is also different.

A good notebook circuit design is more scientific, when using an external power supply, it will disconnect the battery and be powered by the external power supply alone, and when the external power supply is unplugged, it can quickly switch to battery power supply. When the battery is fully charged, it can be automatically disconnected and no longer charged. If this is the case, there is no need to remove the battery.

But not all notebooks are designed like this!! Some laptops still drain the battery when using an external power source; There are also notebooks that don't automatically stop charging when the battery is fully charged. If this is the case, the battery must be removed.

Although it will be beneficial to remove the battery when using the external power supply for a long time, the frequency should not be too high, otherwise the interface of the battery will be worn; Loosening occurs. If there are frequent power outages in your area, never remove the battery, otherwise the damage will be even greater. When the laptop is turned off and the external power supply is unplugged, it is best to install the battery, otherwise it is not very reliable to rely on the coin cell battery on the motherboard to power the CMOS chip for a long time.

2. Laptop batteries should be calibrated every once in a while (about one year). The principle of laptop battery correction is not to activate the battery (lithium-ion batteries do not need to be activated), but to allow the laptop to reconfirm the battery level.

3. If the laptop battery is not used for a long time, the following operations need to be carried out: first fully charge the battery, then use half of the power, and then save it. Don't take too long, repeat the above operations within half a year.

4. The service life of the lithium battery is calculated by the number of full charges, so you don't have to wait for the battery to run out of power, and it does not affect the service life. For example, charging halfway through use is not a complete charge but a full charge.

5. Lithium batteries have no memory, there is no need to discharge, and there is no need to wait until they are used up to recharge, and the rapid power loss mode will consume a large number of lithium ions, so that the battery capacity is reduced. In fact, when lithium batteries are used in various electrical appliances, although the power is exhausted, there is actually a part of the remaining power, which is the protection measure of lithium batteries. Because once the lithium battery is completely depleted, it will no longer be able to be used because it cannot be charged!!

Therefore, lithium batteries should not be left unused for a long time when the power is very low, otherwise the battery will be scrapped directly!!

6. Lithium batteries are different from nickel-cadmium and nickel-metal hydride batteries, and do not need to be activated at all!! Many people's minds are also influenced by nickel-cadmium and nickel-metal hydride batteries, thinking that as long as it is a rechargeable battery, it needs to be activated, which is completely wrong! The so-called activation (long charging) only shortens the life of the lithium battery.

Because the AC clutter used in China will have an impact on the life of the rechargeable battery, fast charging is better than slow charging. In short, try to keep the charging time as short as possible.

Within 7 days, it is a return, and within 15 days, it is a replacement. And you want to keep all the accessories and packaging that you bought when you bought the laptop. This is important!

It is best to go to the after-sales service first to issue a test certificate, saying that there is a problem with the quality of the battery, and you can replace it with a new computer.

To prevent losses caused by false prompts, perform the following steps to confirm once. If it is still prompted to replace the battery, the battery is too worn out and needs to be replaced.

1. Launch the Lenovo Power Manager app and locate the Battery tab. As shown below:

2. Click on battery maintenance, and the following figure appears:

3. Click the battery ruler to reset the settings to reset the battery, as shown in the following figure:

4. Click Continue and follow the on-screen prompts. The finish battery is more accurate.

Prompt replacement is to tell you that the chemical elements of the battery have begun to fail, but you don't replace it, but there is one thing to note, unplug the battery when you directly connect to the power supply to play, and accidents may occur while playing while charging.

The new version should not have such a problem. Failure Analysis:

1. Human causes. The battery has been unplugged and not in place when it is reinstalled. If this is the case, when the AC power supply is not used, it cannot be turned on, and the battery problem will be found immediately.

You can't see the "Replace the battery if there is a problem" prompt. With AC power supply, and the battery is in place, this book uses external power supply to work, and the battery problem is monitored, there will be this warning.

2. In terms of software, if the power management program has an error report, you can use the system restore function to restore it to the factory state to verify whether it is the cause. No, next.

3. In terms of hardware, the hardware power management module is sick, and the error information is fed back to the system to send a notification; When there is a problem with the internal charge and discharge protection circuit components of the battery (the possibility of the new battery being bad is very small), it is monitored and found by the management program, and the alarm is notified. Compress the faulty junction by replacing it with a new battery. The replacement is invalid, and the power module is problematic.

Effective, then the galvanic battery component is a problem. With reasoning and analysis, the problem is as simple as that.

4. Article 3 is a serious situation, it is indeed a product quality problem, and the warranty will be replaced according to the regulations.

Possible reasons are:

1. The battery is not installed in place, resulting in a false alarm in the system;

2. Battery failure, or laptop failure;

Solution: 1. Shut down the battery, remove the battery and install it again.

2. Send it to the brand's special maintenance station or service point, and ask professionals to analyze and deal with it.

See if the contact activity is not fixed below.

If it doesn't work, go to customer service We have a notebook in our dormitory, and we changed the motherboard in a month, also because the battery can only last 10 minutes.

If the system is faulty and incompatible with the hardware, you can try to replace the installed system again.

If the above faults persist, it means that there is a problem with your battery or motherboard, and it is generally more likely that the motherboard is faulty.

See if the computer can be used with a single battery, if it can't be used, the battery is broken. The battery can be replaced with the new machine.

See if the battery is not plugged in properly. The contact between the battery and the computer is not good.

If it has been used for 3 years, it is recommended to replace it with a new battery.

Before changing the battery, you can try the following:

1. If there is a problem with the battery mode setting, you can change the battery mode;

2. In the pop-up power management interface, select the power mode according to your actual needs. From left to right: Energy Star mode, High Performance mode, Balanced mode, Super Energy Saving mode, as the yellow icon selected in this example means "High Performance Mode"; As shown in Fig

2. The battery life has expired, and it can only be used to replace the new battery after the sale.

It's been 3 years, change it, don't repair it, I personally think, don't buy a battery on **, I don't know if it's new, I'm afraid that it will be broken again in a few days, or go to Lenovo after-sales service, spend more money, and be safe.

Mine is the same as you, but the detection loss is 78%, a year and a half of V460

1.First of all, read the manual carefully...

2.When the battery is found to be low, the battery must be charged or replaced with a fully charged battery;

3.The battery of the laptop does not need to be fully discharged, and it is generally necessary to keep %30 %50;

4.It is recommended that after the recharging is completed, you should continue to put the battery on the computer to prevent small particles from entering the computer, we all use this, because after the charging is completed, the charger will be automatically disconnected, even if the power drops, it will not be charged immediately. Therefore, plugging in the battery will basically not affect the lifespan.

5.Unplugging the battery will automatically consume the battery power, and it will shorten the life if not used for a long time.

1. When using battery power supply, try to remove the peripheral hardware that is not used to minimize the discharge current.

2. Room temperature (20-30 degrees) is the most suitable working temperature for the battery.

3. It is recommended to carry out battery power correction once every three months on average.

4. Minimize the number of times the battery is used.

5. In ordinary use, it is necessary to prevent exposure, moisture, chemical liquid erosion, and contact between battery contacts and metal objects.

6. When the battery is not full, try not to plug and unplug the adapter frequently.

7. If the power drops caused by not using the battery for a long time, charge and discharge it regularly, preferably once or twice a month.

8. If the battery is not used for a long time, the reserved power and storage temperature are as follows: (the data on Master Lu's official website has not been verified by me).

The percentage is the percentage of the saturation state relative to the initial value at that time.

Storage Temperature: 40% State of Charge, 100% State of Charge.

0 degrees 98% (after one year) 94% (after one year).

25 degrees 96% (after one year) 80% (after one year).

40 degrees 85% (after one year) 65% (after one year).

60 degrees 75% (after one year) 60% (after 3 months).

This is incorrect. The laptop is designed with the battery in mind, and there is no problem with using it, but it is best to use the battery once a week. It is not connected to external power and uses up the power of the battery.

Continue to use the external power supply. This keeps the battery running at its best.

Yes, when using the power supply, take the battery off, and use the battery to use up the power and then fill it up.

With the rapid development of the times, the use of notebooks has been quite extensive, then the problem comes, what should we do when we use a notebook when there are suddenly various failures, it may be the best solution to send it for repair, but it is not the only way, today let's take a look at how to solve the problem of laptop power consumption.

1. Battery failure:

Soul: Create a circle of like-minded friends.

Ad. If, laptops.

The battery is aging or leaking, etc., and the computer will naturally not be able to charge normally. Therefore, after the computer is powered on, you can feel whether the battery part will be hot, if the battery does not have any temperature in the state of charging for a long time, it is likely to be a battery failure. It is recommended to go to a computer repair shop to replace the battery in time.

2. Software failure:

Probably due to the computer's built-in "battery protection mode", the power management software will disable the battery charging and discharging after detecting the user's use of AC power, so as to extend the life of the battery.

3. Do not use the battery for a long time.

Although connected to the outside.

The battery should not be used when connected to the power supply, but the practice of not using the battery for a long time is also wrong, the battery capacity.

It needs to be activated periodically, and proper use appears more accurate. In particular, every time you use the battery, you should pay attention to the battery before charging, and try not to unplug it when it is not fully charged, and after it has been fully charged, you should use the battery or power adapter alone.

The two should not be used together.

4. Replace the battery cell.

or deep discharge.

If the battery is due to the aging of the battery, we can only solve the problem by replacing the battery cell or deep discharge, but these actions may cause the battery to be damaged or unusable, so remember to be careful before moving.

5. If none of the above methods can be solved, then your notebook may have a relatively big problem and need a more professional solution, and the only way is to send it for repair.

1. The remaining battery time (power) prompted by the system is only an instantaneous reference value, and the actual battery life time is directly related to the operation of your current computer

1. Reduce the brightness of the screen, reduce the use of built-in optical drives and speakers.

2. Turn off idle wireless network cards, Bluetooth devices, etc.

3. Adjust the power consumption mode to "energy saving" and "balanced".

Second, the battery is a consumable product, it is normal to have a certain amount of loss, and after a period of use, the battery life will become shorter and shorter. You can try to correct the battery level by fully charging and discharging the battery, here's how:

1. Unplug the external power supply, turn on the battery only and enter the BIOS.

2. Wait for the battery to run out until it automatically shuts down.

3. Plug in the external power supply, turn on the machine normally, and continue to charge until the power is fully charged to 100%.

3. Regardless of whether the battery is installed in the computer or not, there will be a phenomenon of self-discharge (about 1% a day, slightly different according to different models).

4. If the above three situations are excluded and the laptop battery is still draining quickly, it is recommended that you consider repairing and replacing the battery.

There are too many programs that the computer reopens at the same time, causing the battery to drain quickly.

2. There is too much dust inside the computer, and the heat dissipation is not good, so check whether the working frequency of the heat dissipation device is normal.

3. The battery is old, and the capacity is significantly reduced, which greatly reduces the actual use time of the battery, and you can go to the maintenance center to replace the battery.

4. The computer can be set to power-saving mode to reduce the CPU working frequency to reduce battery consumption, but the symptoms are not cured, and the power supply IC may be affected by the rapid power consumption for a long time.

2. Solution:

1. Maintain the laptop's battery.

Don't keep plugging in the power supply for a long time, in addition, don't wait until the battery is exhausted and shut down before charging, and plug in the power cord as soon as possible for the remaining 10 or so, which is the most conventional maintenance method;

2. In the absence of an external power supply, it is best not to play games or watch movies, because these programs consume power quickly;

3. Unplug the external equipment, such as a mobile hard disk or U disk inserted into the computer, although the power consumption in this situation is not too large, but the accumulation will also affect the power of the computer.

4. Go to the maintenance center to replace the original battery, which is not expensive and the maintenance speed is fast.
