电池图标位于Windows任务栏的右下角。默认情况下，Windows任务栏位于屏幕底部。如果电池图标上出现一个红色x，那就说明电池存在问题了。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/7\/77\/Check-Laptop-Battery-Step-2.jpg\/v4-460px-Check-Laptop-Battery-Step-2.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/77\/Check-Laptop-Battery-Step-2.jpg\/v4-728px-Check-Laptop-Battery-Step-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

随后会出现一个窗口，显示更多电池信息。窗口顶部会告诉你电池寿命还剩多少。如果电池有问题，电池窗口的顶部会显示详细信息。如有需要，Windows会告诉你是否需要更换电池。

“开始”菜单是任务栏左下角带有Windows图标的按钮。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/1\/1a\/Check-Laptop-Battery-Step-4.jpg\/v4-460px-Check-Laptop-Battery-Step-4.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/1a\/Check-Laptop-Battery-Step-4.jpg\/v4-728px-Check-Laptop-Battery-Step-4.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

当你右键点击“开始”菜单时，它会出现在弹出菜单的中间。这样会打开PowerShell提示符。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/0\/00\/Check-Laptop-Battery-Step-5.jpg\/v4-460px-Check-Laptop-Battery-Step-5.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/0\/00\/Check-Laptop-Battery-Step-5.jpg\/v4-728px-Check-Laptop-Battery-Step-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

这条PowerShell命令将生成一份电池报告。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/f\/fb\/Check-Laptop-Battery-Step-6.jpg\/v4-460px-Check-Laptop-Battery-Step-6.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/fb\/Check-Laptop-Battery-Step-6.jpg\/v4-728px-Check-Laptop-Battery-Step-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

这样就会生成电池报告，它可以在网页浏览器中打开。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/0\/0d\/Check-Laptop-Battery-Step-7.jpg\/v4-460px-Check-Laptop-Battery-Step-7.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/0\/0d\/Check-Laptop-Battery-Step-7.jpg\/v4-728px-Check-Laptop-Battery-Step-7.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

默认情况下，电池报告将会保存到C:\users\username\battery report.html。电池报告可以在任何浏览器中打开。它里面包含了电池类型、使用历史、容量和估计容量等信息。

它位于菜单栏的左上角。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/5\/5a\/Check-Laptop-Battery-Step-9.jpg\/v4-460px-Check-Laptop-Battery-Step-9.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/5\/5a\/Check-Laptop-Battery-Step-9.jpg\/v4-728px-Check-Laptop-Battery-Step-9.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

它是菜单栏中的第一个选项。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/c\/c5\/Check-Laptop-Battery-Step-10.jpg\/v4-460px-Check-Laptop-Battery-Step-10.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c5\/Check-Laptop-Battery-Step-10.jpg\/v4-728px-Check-Laptop-Battery-Step-10.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

它在“关于本机”中“概览”选项卡的底部。这样将打开一个包含各种报告的菜单。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/f\/f0\/Check-Laptop-Battery-Step-11.jpg\/v4-460px-Check-Laptop-Battery-Step-11.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/f0\/Check-Laptop-Battery-Step-11.jpg\/v4-728px-Check-Laptop-Battery-Step-11.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

它在左边栏菜单的“硬件”下面。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/7\/78\/Check-Laptop-Battery-Step-12.jpg\/v4-460px-Check-Laptop-Battery-Step-12.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/78\/Check-Laptop-Battery-Step-12.jpg\/v4-728px-Check-Laptop-Battery-Step-12.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

你可以在“健康信息”下找到电池的状态，在“电池信息”下面。“状态”旁边会显示“正常”、“尽快更换”、“现在更换”或“修理电池”。
