如果当您打开Surface设备时，它卡在上面并且无法通过显示 American ^(Surface)Megatrends的黑屏，那么这篇文章旨在帮助您。在这篇文章中，我们将提供您可以尝试帮助解决此问题的可能解决方案。

已请求更改配置以清除此计算机的TPM

如上图所示，您看到的是一个黑屏，顶部是美国大趋势。该屏幕包含可信平台模块^{(Trusted Platform Module)}( TPM ) 设置的配置选项。

值得注意的是，此屏幕可能会在Surface 恢复或重置后出现- 它告诉您已请求更改TPM配置。^(TPM)

Surface 卡在黑屏上

如果您遇到 显示 American Megatrends 问题的 Surface 黑屏^{(Surface black screen showing American Megatrends)}，您可以按照以下说明解决问题。

如果您在 Surface 上看到 American Megatrends TPM屏幕，请执行以下操作：

注意^(Note)：您需要Surface Typing Cover或另一个USB键盘来完成此解决方案。

• 按F12。（如果您使用的是Surface Typing Cover，请按Fn+F12。）

这将保留您当前的TPM设置，并且您的 Surface 将继续使用Windows。

• 如果Windows成功启动，请继续安装最新的 Surface 和 Windows 更新^{(install the latest Surface and Windows updates)}，以帮助防止将来出现问题。
• 如果Windows无法启动并且 American Megatrends TPM黑屏再次出现，请联系 Microsoft 支持^{(contact Microsoft Support)}。

可信平台模块 (TPM)^{(Trusted Platform Module (TPM))}技术旨在提供基于硬件的安全相关功能。TPM芯片是一种安全加密处理器，旨在执行加密操作。该芯片包含多种物理安全机制，使其具有防篡改功能，恶意软件无法篡改TPM的安全功能。

使用TPM^(TPM)技术的一些主要优势是您可以：

• 生成^(Generate)、存储和限制加密密钥的使用。
• 使用 TPM^{(Use TPM)}技术进行平台设备身份验证，方法是使用 TPM 的唯一RSA密钥，该密钥被刻录到自身中。
• 通过采取和存储安全措施来帮助^(Help)确保平台完整性。

最常见的TPM功能用于系统完整性测量以及密钥创建和使用。

Surface stuck on black screen that says American Megatrends

If when уou power-on your Surface dеvice and it’s stuсk on and won’t paѕs the black screеn showing Amеrican Megatrends, then this post is intended to help you. In this post, we will provide the possible solutionѕ you can try to help remеdiate this issυe.

A configuration change was requested to clear this computer’s TPM

What you see as shown in the image above is a black screen with American Megatrends at the top. The screen contains configuration options for the Trusted Platform Module (TPM) settings.

It’s worth noting that this screen may appear after a recovery or reset of your Surface – it tells you that a TPM configuration change was requested.

Surface stuck on a black screen

If you’re faced with this Surface black screen showing American Megatrends issue, you can follow the instructions below to resolve the issue.

If you see the American Megatrends TPM screen on your Surface, do the following:

Note: You’ll need a Surface Typing Cover or another USB keyboard to complete this solution.

• Press F12. (If you’re using a Surface Typing Cover, press Fn+F12.)

This will keep your current TPM settings, and your Surface will continue to Windows.

• If Windows starts successfully, proceed to install the latest Surface and Windows updates to help prevent future problems.
• If Windows fails to start and the American Megatrends TPM black screen appears again, contact Microsoft Support.

Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. The chip includes multiple physical security mechanisms to make it tamper-resistant, and malicious software is unable to tamper with the security functions of the TPM.

Some of the key advantages of using TPM technology are that you can:

• Generate, store, and limit the use of cryptographic keys.
• Use TPM technology for platform device authentication by using the TPM’s unique RSA key, which is burned into itself.
• Help ensure platform integrity by taking and storing security measurements.

The most common TPM functions are used for system integrity measurements and for key creation and use.
