Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported false
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true

答案1
您必须对电源进行压力测试。
首先，你需要一种方法来监控电源提供的电压。通常你可以找到主板制造商提供的实用程序。以前我使用 speedfan。
那么你在寻找什么？偏差大于 + 或 - 5%。在 12v 导轨上，电压为 11.4v 至 12.6v，在 5v 导轨上为 4.75v 至 5.25v。3.3v 也适用同样的原理。
如果您的电源严重超出规格，您的计算机很可能会立即冻结。
现在你的监视器已经开始运行富马克。这会给您的 GPU 带来压力。如果它运行超过 10 分钟并且您的电压不会低于 5%，那么这是一件好事。
现在您需要同时运行 Prime95 之类的程序来同时对 CPU 和 GPU 施加压力。
如果任何电压低于额定电压的 5%，则您可能发现了问题。
