Windows 11/10 用户有时会面临一段时间后可能会有点烦人的问题，尤其是当您看到新的花哨更新带来的新错误与修复的错误一样多时。好在哪里有问题，哪里就有解决方案。如果您的笔记本电脑或电池已经损坏，它可能会充电缓慢 - 但一些用户报告说他们即使在新设备上也面临这个问题。如果您的 Windows 11/10/8/7 笔记本电脑需要永远或很长时间才能充电，以下建议可以帮助您在将问题交给技术人员之前自行识别和解决问题。
Windows 笔记本电脑电池(Windows Laptop Battery)充电缓慢
可能的原因可能是：
- 电池旧或损坏
- 充电器与您的 PC 不兼容。
- 充电器的功率不足以为您的 PC 充电。
- 充电器未连接到 PC 上的充电端口。
笔记本电池不充电
以下是您可以尝试解决笔记本电脑(Laptop)电池不充电问题的一些方法：
1]执行硬重置
此解决方案通常在设备（带有可拆卸电池）充电缓慢时起作用，因为它不断插入。以下是如何去做：
- 关闭Windows设备的电源。
- 断开充电器并从设备中取出电池。
- 按住电源按钮至少 30 秒。这将使主板的电容器放电并重置一直处于活动状态的内存芯片。
- 重新插入电池，插入并为设备充电。
如果这不起作用，请尝试更新BIOS。
2]更新BIOS
如果据报道您设备的典型充电问题已在更高版本中得到修复，请更新BIOS。方法如下：
- 按 Win(Press Win)键 + R 键进入运行(Run)窗口。
- 键入msinfo32并按“Enter”。
- 检查系统信息(System Information)窗口右侧窗格中的BIOS 版本/日期信息。记下版本。
- 检查这是否确实是您模型的最新可用版本。如果没有，请按照支持网站上的说明更新 BIOS 。(update the BIOS)
如果您不想更新BIOS，或者如果它已经更新但问题仍然存在，请查看下一点。

3]电池校准
如果您不系统地给电池充电，不规律的电池放电和充电周期可能会干扰充电功能。您需要重新校准电池，方法如下：
- 将电池放电 100%。
- 在“关闭”(Off)模式下，让设备充电大约比预计充满电所需的时间多一个小时。
- 插入充电器后，打开设备以确保其已充满电。
- 断开(Disconnect)充电器并照常使用。在电量不足之前避免(Avoid)充电，并且在设备完全充电之前不要拔下插头。
保持这种充电习惯，问题就不会再出现了。但是，如果电池校准不是问题，请转到方法 4。

4]执行电池检查
随着设备老化，电池性能将不断下降。使用BatteryInfoView等应用程序来监控当前电池的最佳容量性能。如果电池没有达到标记，请更换电池。您还可以使用电源效率诊断报告工具生成电池健康报告(Battery Health Report)。
5]执行电压检查
如果上述解决方案均无效，则设备的每个部分都可以正常工作，但充电器却不行。要检测有故障的充电器，请使用电压测试仪或万用表进行电压测试。如果电压读数低于打印的原始输出，则需要更换充电器。在您的设备上使用另一个兼容的充电器并查看。

根据微软(Microsoft)要考虑的几点：
- 充电线不符合充电器或 PC 的电源要求。
- 一些USB充电器，例如微型USB和USB-C充电器，使用专有充电器。因此，您的 PC 可能只能使用 PC 制造商提供的充电器。
- 与不使用 USB-C 连接充电的 PC 相比，带有 USB-C 连接器的 PC 具有更高的(USB-C)功率限制(USB-C)。USB-C最高可支持 5V、3A、15W。如果该连接器支持标准的USB 供电(USB Power Delivery)，则它可以更快地以更高的功率水平充电。
- 为了获得最快的充电时间，您的 PC、充电器和数据线必须支持行业标准。您的充电器和充电电缆必须支持 PC 所需的最快充电时间的功率水平。例如，如果您的 PC 需要 12V 和 3A 进行充电，那么 5V、3A 充电器将不是为您的 PC 充电的最佳选择。

Windows Laptop Battery Plugged in but Charging slowly or Not charging
Windows 11/10 uѕers at times face issues that can get a little annoying after а while, esрecially when you see that a new fancy update brings jυst abоut as many new bugs as it fixеs. The good thing is where there is a problem, there is a ѕolution. If your laptоp or batter has beсome, it is possible that it maу charge slowly – but some users have reported that they face this problem even on a new deνice. If your Windows 11/10/8/7 laptop is taking foreνer or a long time to charge, hеre are suggestions that cоuld help yoυ identify & fix the problem yourѕelf before уou take it to a teсhnіcian.
Windows Laptop Battery charging slowly
The possible reasons could be:
- The battery is old or damaged
- The charger isn’t compatible with your PC.
- The charger isn’t powerful enough to charge your PC.
- The charger isn’t connected to the charging port on your PC.
Laptop battery not charging
Here are a few things you could try to fix Laptop battery not charging problem:
1] Perform Hard Reset
This solution usually works when the device (with removable battery) charges slowly because it is constantly plugged in. Here is how to go about it:
- Switch off the power of the Windows device.
- Disconnect the charger and remove the battery from the device.
- Press and hold the power button for a minimum of 30 seconds. This will discharge capacitors of the motherboard and reset memory chips that were constantly active.
- Reinsert the battery, plug in and charge the device.
If this doesn’t work, try updating the BIOS.
2] Update BIOS
If the charging issue typical to your device is reportedly fixed in a later version, update the BIOS. Here is how:
- Press Win key + R key to get to the Run window.
- Type msinfo32 and hit ‘Enter’.
- Check the BIOS version/Date info on the right pane of the System Information window. Note down the version.
- Check if this is indeed the latest available version for your model. If not, update the BIOS following the instructions on the support website.
If you don’t want to update BIOS or if it is already updated and yet the problem persists, check out the next point.

3] Battery calibration
If you do not systematically charge the battery, the irregular battery drainage and charging cycles can meddle with the charging function. You need to re-calibrate the battery, and here is how:
- Discharge the battery 100%.
- In the Off mode, leave the device on charge for about an hour more than the estimated time it would take to charge fully.
- With the charger plugged in, turn on the device to make sure it has fully charged.
- Disconnect charger and use as usual. Avoid charging until the charge is low and do not unplug before the device has charged completely.
Maintain this charging ritual, and the issue will not reappear. If however, battery calibration wasn’t the issue, go to method 4.

4] Perform a Battery check
As the device ages, the battery performance will keep dropping. Use an app such as BatteryInfoView to monitor current battery performance with respect to its optimum capacity. Replace the battery if the battery is not performing up to the mark. You could also generate a Battery Health Report using the Power Efficiency Diagnostic Report Tool.
5] Perform a voltage check
If none of the above solutions worked, maybe every part of your device is fine, but the charger is not. To detect a faulty charger, perform a voltage test with a voltage tester or multi-meter. If the voltage reading is lower than the original output printed, the charger needs to be replaced. Use another compatible charger on your device and see.

Points to consider according to Microsoft:
- The charging cable doesn’t meet the power requirements for the charger or PC.
- Some USB chargers, such as micro USB and USB-C chargers, use a proprietary charger. Therefore, your PC might only be able to use a charger from your PC manufacturer.
- A PC with USB-C connectors has higher power limits than a PC that doesn’t charge using a USB-C connection. USB-C can support up to 5V, 3A, 15W. If the connector supports USB Power Delivery, which is a standard, it can charge faster and at higher power levels.
- To get the fastest charging time, your PC, charger, and cable must support the industry standards. Your charger and charging cable must support the power levels that the PC needs for the fastest charging time. For example, if your PC requires 12V and 3A for charging, a 5V, 3A charger won’t be the best for charging your PC.
