Laptop charging is not as fast as electricity

It's the battery that's wrong, not the adapter.

Problems with my laptop.

There have been such problems before, most of them are old machines, and if you don't charge it, the battery will use it quickly, just change the battery, but if you are a new computer, it is the manufacturer's problem.

Go for repairs, you can't directly supply AC power, it must be a problem with the charger or motherboard power supply.

Electronic products must be broken, but it doesn't mean that the original ones won't be broken.

1. The reason why the laptop consumes power quickly:

1. There are too many programs that the computer reopens at the same time, resulting in fast battery consumption.

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.

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.

The computer shuts down after each charge, and the next day you find that it is dead, maybe because the power is lost too quickly, or maybe the battery is aging.

Here's how to solve the problem:

1. Find "Control Panel".

2. Click to open "Hardware and Sound".

3. Click "Battery Options".

4. Select the option "Change the function of the power button".

5. Click "Change Currently Unavailable Options".

6. Turn off the "Shutdown Settings" option to reduce the battery consumption of the laptop when it is powered off.

7. If none of the above methods can solve the problem of power failure, it may be that the battery has been used too many times and the battery has begun to age, at this time, you can consider replacing a new laptop battery.

When the laptop is out of battery, you need to connect it to the original adapter to charge it directly.

Some notebook manufacturers have battery energy-saving control charging software, see if there is such software on the machine, the software can set the value of the battery charge to how much. If the battery power increases, it means that the battery is over-discharged, and it can be charged in time.

If the battery level is still 0 after charging for a long time, it may be a battery failure and it is recommended to send it for repair.

Laptop.

There is no power, plugging in to charge but can't charge it, what's going on? What to do.

1. Cause analysis.

1. Software problems.

Generally speaking, many computer brands such as Dell, Lenovo, Sony, etc., will equip their laptops with power management software, if a certain "battery protection mode" is enabled, 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 battery life. So, if you find that your laptop is not charging, you can first go to the relevant power management software, turn off the battery protection mode or check the no charging option, and if there is no problem with the hardware, the battery will be able to charge.

2. There is a problem with the hardware itself, the battery itself has a hardware failure, generally speaking, we can use to restart the computer, replug and unplug the battery to judge, if the battery still cannot be charged, you may wish to install some hardware detection applications to get the approximate battery loss reference information. If it is determined that the battery hardware is faulty, do not open it by yourself or try to repair it, there is a certain risk, it is recommended to take it for repair.

2. Security repair methods.

When entering the BIOS when the computer boots up, it is common to find the "Start Battery Calibration" option in the Power item, which is "Start Battery Repair", and usually the user is reminded to connect the power adapter first.

Carry out a full charge, then a text will be displayed prompting the user to disconnect the AC power supply to the win7 system.

The notebook will be continuously discharged until the power is completely exhausted, and then the notebook will automatically shut down, we can connect the power adapter to charge, but do not turn it on, and the whole process will be completed after the charging indicator is turned off. Security fixes: enter the BIOS when the computer starts, usually find the "Start Battery Calibration" option in the Power project, that is, "Start Battery Calibration", generally speaking, the user will be reminded to connect the power adapter for full charging, and then the text will be displayed to prompt the user to disconnect the AC power supply, the win7 system will continue to discharge the notebook until the power is completely exhausted, and then the notebook will automatically shut down, We can connect the power adapter to charge, but don't turn it on, and the whole process will be completed after the charging indicator is off.

Note: The BIOS battery repair process can take up to 5 hours, so be sure to do it when you don't need to use the laptop, if this still doesn't improve the battery condition, then it can only be said that the battery is probably broken, you can send it for repair or buy a new original battery.

The computer is good while charging. Charging a laptop while playing is good for the computer, and now the computer and lithium battery are controlled by a charging valve. The taboo of lithium batteries is long-term discharge without charging or repeated charging without one-time sufficiency.

When plugging in an external power supply, charging and playing at the same time will not affect the life of the battery. It should stop charging automatically when the battery is fully charged. And at this time.

The power used by the computer comes from an external power source.

For users who like to play games on a daily basis, it is best to plug in the power supply when playing games, because if the EC finds that the battery is in short supply for the game, there is a high chance that there will be a black screen restart.

Precautions for using a laptop.

When using a laptop, it should be noted that because the laptop is very sophisticated, it is less resistant to dirt than the desktop, plus the laptop is often taken to different environments to use, and it is more likely to be soiled than the desktop; So you need to take good care of it. In addition, most laptops' carrying cases are not waterproof , so be aware of waterproofing. When using the laptop, please be careful not to drop food, water, etc. into the keyboard, so that the surface of the keyboard is stained with unclean substances, which will affect the service life of the keyboard.

If you accidentally spill drinks into the keyboard, please clean it immediately to avoid corrosion of the keyboard circuit module; The motherboard, optical drive, floppy drive and other components are short-circuited and burned out, causing unnecessary losses.

Hello! The laptop can be charged while being used, and if it is used in a fixed place for a long time, it is also necessary to use the battery separately at a time to maintain the vitality of the battery.

Yes, the laptop battery can be connected to the power supply if it cannot be charged, but it is best not to remove the battery on the laptop, the rechargeable battery can also stabilize the voltage if it cannot be charged, and it will be smoother to use.

First, try to perform a clear CMOS (EC reset).

1.Please remove all external devices, such as external hard drives, printers, memory cards, optical drives (if it is an internal one, please remove the optical disc), as well as adapter cards in card readers, etc.

2.Power off your computer.

3.Remove the power adapter.

4.Remove your laptop's battery (if your computer is a removable battery module).

5.Press and hold the power button for 40 seconds (hold and hold) to perform an EC reset.

6.Reconnect the power adapter and battery, and turn on the device to see if the problem is resolved.

Second, perform battery problem diagnosis through myasus.

1.Enter [myasus] in the Windows search bar, and then tap [Open].

If you can't find myasus, it means that your computer may not have it installed, so install myasus.

2.In the myasus window, click [System Diagnostics].

3.Tap [Battery Issues].

4.Connect your computer to a power source, and then tap [Start Check].

5.If an error is detected, try the troubleshooting advice in myasus for the error issue. If the problem persists, continue with the troubleshooting steps below.

3. Reinstall the battery power adapter driver via Device Manager.

1.Enter [Device Manager] in the Windows search bar, and then tap [Open].

2.Uninstall the battery driver. Click the triangle next to the [Battery] device type, then right-click [Microsoft ACPI Compatible Control Method Battery] and select [Uninstall Device].

3.Tap [Uninstall].

4.In the Battery Device Type, right-click [Microsoft AC Adapter] and then tap [Uninstall Device].

5.Tap [Uninstall].

6.Microsoft ACPI compatible control method battery and Microsoft AC adapter drivers are uninstalled, please restart the computer, the driver will be automatically reinstalled, and reconfirm whether the problem is solved.

In the case of the Lenovo Legion Y9000P, it can't be charged when plugged in because the power adapter is not connected to the outlet, or there is no power at the outlet. You can try to plug and unplug the plug again, if the indicator light is still not on, replace the adapter and try the width.

You can also change the Power Management setting. Right-click on the "Power" icon in the taskbar and click to select "Power Options" (which can also be opened through the control panel); Click "Schedule displayed on the power indicator" and correspond to "Change plan settings" on the right.

Click "Change Advanced Power Settings Alert" in the lower left corner; Switch to the "Lenovo Power Management" tab and click "Start Lenovo Power Management Software"; Open the Energy Management page and select Maximum battery life in the Power column.

At this time, click the third icon of the battery, "Battery Information", and you can view the current charging status as "Charging"; Re-check the power supply in the lower right corner, and you can see that it says "The power is on, charging", which means that it is ready to be charged.

The reason for this may be that the battery has not been charged for a long time, resulting in severe power loss after the battery is depleted internally.

The reasons are as follows:

1. Check the battery settings of the notebook, whether the battery charging is disabled, and some notebook battery management software also has the function of disabling charging.

2. It may also be that it has been left for too long and is useless, resulting in poor contact. Open the notebook to clean the dust, unplug the power cord and battery, and the lead pants can also be solved. If there is no problem with the check settings, then most of them are the internal control circuits or cells of the laptop battery.

If there is a problem, it needs to be taken for repair.

3. In addition, it is worth mentioning that some notebook batteries have been used for a long time, and they are discharged excessively vertically and widely, resulting in the appearance that 0% of the available power supply has been turned on and not charged, and they will be repaired later, even if they are repaired, the battery life and life will not be long, and it is best to buy a new notebook battery.

Precautions

Some laptops.

Users, take out the laptop battery factory area, put it away, this kind of battery removal and storage, will also wear out the battery, resulting in the battery life of the laptop getting worse and worse.

Many friends often use the battery until the battery is exhausted, until the computer automatically shuts down, which is easy to damage the battery.
