Lenovo Y470 notebook,Often use it to run out of power and automatically sleep,Does this have an impa

Hello landlord, upstairs quite a lot of power when the battery is removed and put aside. Personally, it is very not recommended to do this, first of all, the battery is not used for a long time, and the impact on the battery is also very large, and it needs to be charged and discharged once after a period of time, which is very troublesome. Secondly, regardless of how much this has a protective effect on the battery, if the power is suddenly cut off, and there are important things that are not saved, then I really want to die.

The landlord's laptop is often charged and discharged, which does have an impact on the battery. The best way to use a laptop battery is to "consume a small amount of power steadily", plug the battery into the notebook, and keep 50% of the power (achieved through software), which has the best effect on battery protection. It is recommended that the landlord reduce the number of complete charging and discharging, otherwise the battery may wear out faster.

I hope to help the landlord If you have any questions, please feel free to ask

My legion: help others-oriented, to this member!

Batteries all have a certain lifespan, so repeated use of batteries will shorten the life of the battery and have no other effects. Of course, if the battery is broken, you can also buy another battery and install it, a few hundred dollars.

It's better to follow Lenovo's own instructions. Your own approach is certainly not good for the battery.

Don't listen to them, every time it is completely discharged, it is good for the battery, because the battery is completely discharged, so that the loss of the battery is relatively small, which is good for the battery, so that your battery standby time is definitely much stronger than that of the infrequently used, and it is not bad for the computer, because it will automatically sleep.

When using, it is best to take out the battery and use an external power supply. Because the battery charge life is only hundreds of times.

Fainting. If you use it like this, it's no wonder that the battery doesn't break. Every time I use the notebook, I always plug it in, you must know that the notebook uses the external AC power supply of the wiring, not the battery, so that the battery is left on hold, increasing the life of the battery...

Laptop batteries come in handy when they're out and about.

If you can, you don't need to use a laptop battery.

Laptop batteries are generally used when they cannot be connected to an external power source.

Theoretically, no, because his auto-sleep itself is a protection for the computer, of course, it is still recommended to charge it when the computer reminds it.

Today's laptop batteries are all nickel-metal hydride batteries, which have no memory function and do not need to be discharged, so you can install the battery on the computer and use it, and it is best to connect it to an external power supply.

When you plug in the external power supply, you don't need to unplug the battery, but you have to make sure that the battery is completely put once a week.

I think you might be too expensive with the board, so I think you should charge it when you have about 15% left. If you use it like this, it's over!

To solve this problem, it is necessary to popularize the internal structure of the computer switching power supply, so that users can use the computer with confidence.

The switching power supply of the computer, the live wire and the neutral line in the internal power line are connected in series with a capacitor at the DC ground end, and there is also a capacitor in series between the primary DC high voltage and the secondary DC ground, the three capacitors are called Y capacitors in professional terms, and the common name is called safety capacitors, which are used to filter out the common mode interference of the power supply (it can also be simply understood to filter out electromagnetic high-frequency interference), and it is obvious that the capacitor is used to improve the performance of the computer switching power supply. This capacitor has a very high safety factor and will not cause leakage accidents due to breakdown.

However, all capacitors will have leakage current, and this leakage current is shown on the computer to some people to feel the effect of leakage or static electricity, but in fact, this leakage current is very small, within the safety range, and will not cause harm to people.

So you can use it with confidence.

In fact, most of the houses in the construction are installed with protective ground wires, and the leakage current generated by the computer switching power supply is released through the protective ground wire, so the user can not feel the existence of this phenomenon. Therefore, by installing a protective ground wire, the feeling of leakage or static electricity can be eliminated. However, making a PGD requires a certain amount of skill, so you can ask someone to help you do it.

In fact, many buildings in rural areas do not have protective ground wires, but the relative safety factor of electricity is poorer.

It is also worth noting that since there is a sense of leakage, why does the leakage protector not act, it is because the leakage current of the computer switching power supply is much smaller than the action protection current of the leakage protector, so the leakage protector does not trip. In this regard, if a leakage that endangers a person occurs, the leakage protector will trip and cut off the power.

Therefore, there is no problem with your computer and it is qualified, which is a common phenomenon and you can use it with confidence.

In addition, static electricity is the enemy of hard disks and laptops, and under normal circumstances, when the humidity is below 40%, it is easy to produce static electricity.

In summer, the temperature is high, there is a lot of moisture in the air, and static electricity is not easy to accumulate. However, during daily use, care should be taken.

When your laptop is leaking, try the following steps:

1. First unplug the external power supply and use the battery for power supply. If the vulnerability condition disappears, then it means that it is a problem with the ground wire of the socket, enter the second step below, if there is still leakage, then contact the dealer for repair.

2. Confirm whether the socket is grounded, and a simple way to do it is to test the socket with a pen or multimeter. If the ground voltage is zero, the socket is grounded. Go to the third step below, otherwise change the socket or rearrange the ground wire.

The sedan power supply you use still has a grounding wire, or your computer is broken, it is best to go to the after-sales service to check it, so as not to lose more.

Go to the after-sales service and let them check it, you can't check it yourself unless you are grounded.

If the laptop cannot be turned on after continuous charging, please debug it according to the following scheme:

1. Release static electricity.

1. If the notebook only has an "external" battery, the operation method is: after the main power is turned off, unplug all the connecting cables and connected devices on the body, remove the external battery, press and hold the power button for 10 seconds, press and hold 3 times, replace the battery after the operation is completed, connect the power adapter and start the computer again.

2. If the notebook uses a "built-in" or "built-in + external" battery, you can find out whether the back of the notebook is a small hole the size of a circular needle's eye, and the word "reset" is written near the hole, you can unplug all the connecting wires and connected devices of the fuselage in the power-off state (there is an external battery that needs to be taken out of the external battery), poke the button in the "reset" hole with a paper clip or card needle, for 15 seconds, and check whether the host has been started after 15 seconds, if not, You need to connect the power adapter (if there is an external battery, the external battery will be connected first, and then the power adapter will be connected), and then the power adapter will be turned on after being connected.

2. Replace the same model power adapter for testing.

3. Try to replace the external battery of the same model for testing.

1. If the machine is fully charged, and the battery cannot be turned on after unplugging the power adapter, it may be that the battery is not charged, and the external battery is replaced.

4. If it still can't be turned on after the above operations, or if it is confirmed that the power adapter or battery hardware is faulty after the replacement test, it is recommended that you consider repairing.

5. If you still can't succeed according to the above methods, you can click on the avatar to enter the "Lenovo Business Service" homepage and consult an engineer online to solve the problem.

Dear Lenovo users, hello!

Hello, please try to turn off the charge and try, if not, try to release static electricity:

1.Please unplug the battery, power adapter, and all external devices (headphones, mice), press and hold the power button for 30s, and then power on the power.

2.If the ThinkPad generally has a built-in battery that cannot be removed, there must be a reset hole, use a straightened paper clip to insert it into the reset hole, press it for a few seconds and turn it on for testing. There is generally no reset hole for external batteries, and the reset operation is carried out by pressing (1).

If it still does not work, it is recommended that you send it to a nearby service station for maintenance, so as not to affect your pleasant use in the future.

If your problem is not solved, you can complain, put forward your valuable opinions, and then transfer to manual service.

Check the socket first, then check the charger, if the charger is plugged into the computer and the light is not on, it means that the charger is broken, take it to the repair appliance and measure the charger to confirm.

In this case, the solution is:

1. Take out the battery of the motherboard, buckle it back, and discharge.

Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2. Clean the dust in the chassis to eliminate the short circuit or poor heat dissipation of the motherboard caused by too much dust.

3. See if the CPU thermal grease is dry, silicone grease is used to improve heat dissipation ability, if there is no silicone grease, the heat may not be dissipated, and the machine will automatically shut down.

It may be that the fan is broken, so take it to the after-sales service for testing.

1. Check whether the power cord is plugged in.

2. Enter the control panel, power options, and change the standby time to turn off the hard disk and turn off the monitor. Save to exit.

3. If it happens to automatically shut down during playing a large game, go to the computer city and spend 50 yuan to buy an aluminum fan to increase heat dissipation.

4. If the machine is used for a long time, it will be taken to clean up the dust, and it must be disassembled in person, and the hardware of the original machine must be replaced carefully.

6. If you can't be sure, take it to customer service for repair during the warranty period.

Basically, the above five points can solve the problem, welcome to ask. (I am original, the excerpt is shameful).

The reasons why the Lenovo Y470 battery has an electric sail and the locust cannot be turned on are:

1. The battery contact is not sold;

2. Computer system failure;

3. Caused by other hardware failures.

Solution: 1. Reassemble and install the laptop battery, and then turn it on;

2. Release the static electricity of the notebook first, and release the static electricity: remove the power cord and the external device of the mouse line light when the state is turned off, and remove the battery, press and hold the power button for 5 seconds, repeat 3 to 5 times, and then install the battery to turn it on;

3. If it still can't be turned on, it is recommended to send it directly for repair and after-sales for detailed and comprehensive inspection and warranty processing.
