Seek help!! Laptop battery failure, laptop battery usage problems!!

I'm a Dell Native user. Now Dell battery quality is far less than it used to be.

According to your description, the battery should have been used for more than a year, and in this case, it should be aging or the charging control circuit is damaged. You can remove the battery, wrap it in a paper towel that can absorb water, wrap it in a sealed plastic bag outside, put it in the refrigerator room, refrigerate it for 3 or 4 days, after taking it out, do not open it, put it in a ventilated place, unpack it after 3 days, put it on and try it, if you can restore the power, you are lucky, if you can't recover, it will be completely hopeless. Remember, it's refrigerated, not frozen.

The battery is seriously aging, for example, a person who is dying can still live with oxygen, and all of a sudden the oxygen is pulled out, and the person is dead, and it is useless to plug in oxygen. That's what it means to describe your battery. Originally in the battery.

Lithium-ion or nickel-metal hydride activity is not good, you run out all at once, and it is inactive. I want to recharge it and I can't activate it.

Know clearly. If you replace it with a new battery, if you fully charge the new battery and use it up, and only use it once, it will be scrapped after half a year, and the battery will be inactive.

The main thing is that your battery has been used for too long and has been seriously aged. Let's see if I can find someone to repair the battery or replace the battery cell for you.

Get it.

Go to the battery repair center and replace the set of batteries inside, but the effect is not as good as the original, and the cost performance is not bad.

No, but it looks like your battery is generally aging, so let's change it.

What's the deal with the 16% loss of the new laptop battery? The measured capacity is actually the stored energy of the battery, which is calculated as:

Battery Nominal Voltage The nominal capacity of the battery.

The voltage and capacity are on the battery label, for example, if the voltage of a battery is 4000mAh, then the capacity measured using the software should be.

If it is higher than this value, it is normal, because the capacity of the new battery is higher than the nominal capacity, if it is lower than this value, it means that the battery has decreased capacity, and there may be a problem with one of the cells inside. It's best to replace it as early as possible within the warranty period.

Note that the warranty period of laptop batteries is much shorter than that of computers, usually only half a year, and if there is a problem, claim as soon as possible. What brand of computer is you?,If there's a power manager driver that's not installed, you can't tell it.。 Mine is IBM, even the battery has been charged several times, there is a record of the prototype, the new battery is important to be fully charged.

Now the circuit of the battery can be fully charged and automatically powered off.

Commonly known as "floating charge".

So no amount of time is useless.

The effect is all the same.

To fully activate the battery, do a few full charging cycles.

It says it's charged, that is, it's charged, just unplug it, it's best not to buy a prototype.

Master Lu's detection is not necessarily accurate! Use professional battery testing software to test it...

Battery drain is a natural process, but if you don't pay attention to it, you will think that it will accelerate! You're losing a little too fast.

You check it below and suggest it in future use:

1) Avoid using universal chargers or inferior chargers.

2) Do not expose the battery to high temperatures (a culprit of irreversible losses!) Or in severe cold, and certainly not in humidity or water.

3) Don't over-deplete the battery, which is also a culprit of the irreversible loss of the battery, remind the charging and timely charging.

4) To make the battery "prolong", try to use an external charger power supply, but do not use the battery for a long time.

(1) Whether the new battery needs to be activated.

In fact, the activation of the battery should have been completed in the factory, and the small amount of power that the laptop battery carries when it leaves the factory is to avoid damage to the battery due to natural wear and tear. The activation of the battery should be carried out without a protection circuit, but the lithium battery itself has a protection circuit, and the purpose of designing the block circuit is to avoid the overcharging and discharging of the battery. We can see whether the battery is charging from the condition of the battery, here is a simple way to judge whether the battery is in the charging state, the battery will emit a certain amount of heat when charging, when the battery is fully charged for an hour (the charger power plug is not unplugged temporarily), you go to touch the battery, at this time you will find that the battery is in a state of room temperature, this is because the battery is no longer in the charging state at this time, of course, there will be no heat.

b) How to charge it properly.

Regardless of whether the notebook uses lithium batteries or nickel-metal hydride batteries, these batteries have a memory effect, nickel-metal hydride batteries have obvious memory effects, and lithium batteries also have memory effects, but its memory effect is smaller than that of nickel-metal hydride. We have heard the so-called lithium battery has no memory effect, which is just an exaggerated statement by some JS, the purpose of which is to mislead consumers. Since the battery lithium has a memory effect, you should try to use up the electricity and then charge it when charging, and don't charge it whenever you want to, so that although it is convenient to use, it will shorten the service life of the battery.

However, there is no need to wait for the battery to run out before charging, which is too troublesome. Although this will not damage the battery because it is protected by the protection circuit, there is no special need for it. In fact, it is enough to charge when the power is less than 3, and the memory effect still exists objectively, but compared to natural loss, it is nothing.

3) Whether the battery needs to be unplugged when using an external power supply.

In fact, it depends on whether you need to charge the battery when you use the external power supply, the number of charging times of the battery is directly related to the life, under normal circumstances, the number of charging and discharging of lithium batteries is fixed, and the charging times are generally only about 500 times, and the maximum will not exceed 800 times. Every time we charge the battery, we reduce the number of times it can be recharged. However, now many notebook manufacturers have taken into account the fragility of the battery, and have added the protection technology for the battery, which will not be charged if it does not meet certain conditions.

Even so, it is recommended that you unplug the battery when you use the computer with an external power supply for a long time, because high temperature is also one of the nemesis of the battery, and the laptop will produce a certain high temperature when in use, which is very harmful to the battery. Of course, if you are not sure about your battery, I still recommend that you unplug your battery and use external power.

Unplug the battery when using the plug, and the life is much longer.

Set it in the power management mode, the computer should be plugged in when not in use, and the battery will be lost if the power supply is not bad. In general, try to plug in the power supply. The battery life is generally quite long.

Have you ever been in a situation where your computer's battery is always running low, no matter what you do? This indicates that the time has come to replace the battery.

Each battery has a design capacity, which usually refers to the amount of power it is designed to hold. Over time, the battery will gradually reduce its ability to hold power. This means that even if your battery is fully charged, the actual amount of power that your battery can hold will gradually decrease.

If there are signs that the battery life is getting shorter and the charging time is also shorter, it is a sign that the performance of the battery has deteriorated. If you notice that the battery is running for less time, it is a sign that the battery's ability to hold power has decreased a lot. Another sign is that your battery is constantly weakening and the charging time is shortening.

If battery performance degrades, even if the battery indicator shows sufficient power remaining (70 or 80%), it can cause your computer to shut down unexpectedly or go to hibernation.

Windows can help you know when your battery won't fully charge, though. When the battery level drops to 40% of its original capacity, i.e., it can only hold 40% or less of its designed capacity when charged, you can see a notification through the battery indicator icon indicating that the battery performance has degraded. This notification is a new feature in Windows 7, and previous versions of Windows can't notify you when your battery performance is slow.

A battery indicator that displays notifications about battery degradation.

Many batteries show some signs of a problem before the battery capacity drops to 40% of its original capacity. In addition, many computer manufacturers have developed programs that can be used to measure battery performance. These programs can detect battery issues more sensitively.

You should first use these programs to check your computer's battery health. For more information about solutions to this problem, see Solutions to Common Battery Problems.

Note: Some computer manufacturers report the design capacity of their batteries as the level at which they were last fully charged. As a result, your battery may be below the warning threshold, but no warning will be displayed. If your computer continues to experience battery drain quickly, but the battery indicator shows that it is fully charged, you should consider replacing the battery.

Check with your computer manufacturer for information on replacing the battery.

Make sure to charge and maintain your battery according to the manufacturer's instructions. Use only the charger and power cord provided by the manufacturer.

Do not allow your battery to overheat or overcool. An overheating battery is an indication of a malfunction and usually means that the battery is not working properly. You should stop using the battery immediately.

Also, make sure that your battery is not exposed to extreme temperatures. The performance of the battery is best at room temperature. Avoid using or storing batteries in extreme temperature conditions.

Use batteries to maintain their lifespan. Do not always plug your computer into AC power. It's a good practice to discharge and charge your laptop's battery once a month. Also, before charging the battery, the battery should be drained.

The second floor is right. I'm not going to say it again, it's normal.
