Win7 notebook does not charge, ask for pointers

This, it should be a software problem, what model of your notebook is? Generally speaking, more than 90% of the battery is not charged!

Lenovo PCs come with built-in Lenovo power management, if you set it to the best battery maintenance. That is, the power is more than 50% and will not be charged.

1. Check the battery to see if the wiring is loose and the connection is not strong.

2. If the circuit is normal and still can't rush in, you can see if the circuit board of the charger of the battery is broken, and try another one.

3. If the circuit is normal and the charger is good, it may be that the circuit board inside the computer is faulty.

1. The power adapter is faulty.

The power adapter has many friends who call it a charger, although it is not accurate enough, but it is indeed very vivid. It is also very simple to determine whether it is not due to the power supply and does not charge, and the replacement method will do. This kind of failure is more common in the maintenance of dell notebooks, dell notebooks use lbk (dell architecture), the charging circuit design is more special, the adapter will not charge if there is a problem, if it is not the original adapter will also have the problem of not charging.

Second, the battery is faulty.

The fault performance of the laptop battery is relatively simple, most of the charging progress has been displayed at 100%, in fact, the battery life is less than a few minutes after removing the power adapter, or the battery cannot be detected directly. Mainly due to the normal wear and tear of the battery itself, notebook batteries, optical drives, and fans are veritable "consumables" in notebook accessories.

3. Motherboard failure.

The non-charging of the notebook caused by the failure of the motherboard is the most encountered in the maintenance of the notebook, because it is a chip-level maintenance, and the non-charging caused by the general power supply and battery will be solved in the hands of the board-level maintenance personnel, and it will not reach our hands.

It may just be a bug in the power detection, as long as the charging indicator flashes, it means that it is charging.

HP's computer battery works like this, when the power is above 90%, it will not be automatically charged, it will prompt that the power is turned on, not charged This is the system in protecting the battery to avoid battery overshoot, so as to increase the service life of the battery After shutting down, the battery is in an unused state This is to make up for the unfilled power The computer has no problems Hope to adopt.

I guess you have a problem with this battery, so let's go and test it.

What to do if your laptop won't charge.

Try plugging the power adapter back in and out to see if the issue resolves.

The laptop cannot be charged, there are several possibilities:

1. Circuit failure, 2. Charging interface failure, 3. Motherboard failure, no matter what the cause is, it is recommended to send the laptop and power adapter to the official after-sales service center, and a professional maintenance engineer will do a detailed test to confirm the specific problem and its cause.

Laptops are also known as portable computers, with built-in batteries that can last for a while even if they are not connected to the power supply, but there are many users who have been to the situation that the laptop cannot be charged, so what should we do if we encounter a laptop that cannot be charged? There are many reasons why the laptop can't be charged, and the following is an introduction to the solution to the laptop can't be charged.

Software Issues:

1. Many laptop brands have their own power management software, such as Dell, Lenovo, Sony, etc., if the battery protection mode is enabled, the power management software will prohibit the battery from charging and discharging after detecting the user's use of AC power, so as to prolong the battery life;

2. When you find that your laptop is not charging, you can first enter the power management software, turn off the battery protection mode or cancel the disable charging option, if there are no other problems, the computer can be charged.

There is a problem with the hardware itself:

1. If it is a hardware failure of the battery itself, we can try to judge by restarting the computer and replugging the battery;

2. If the battery still can't be charged, you may wish to install some hardware detection applications to get approximate battery loss reference information.

3. If it is determined that the battery hardware is faulty, do not open it or try to repair it by yourself, there is a certain risk, it is recommended to repair or replace the battery with a new one.

Power adapter issues:

If the battery cannot be charged, there is a big possibility that there is a problem with the power adapter, you can give the adapter to other normal computers to try to see if it can be charged, and then replace it with a new one after confirming that it is a problem with the adapter.

Security fixes:

1. Enter the BIOS settings when the computer starts, and find the "StartBatteryCalibration" option in the Power project, that is, "Start Battery Repair";

2. After that, 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, and 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 late for charging, but do not turn it on, and the whole process will be completed after the charging indicator is turned off.

3. The battery repair process of BIOS may take 5 hours, so be sure to operate it when you don't need to use the laptop, if you still can't use it, it is recommended to replace the battery with a new one.

The above is all the content of the solution to the problem that the notebook can't be flushed, and you can refer to the above methods to see if it can be solved, and then repair it.
