Description

一种系统恢复方法及装置
本申请要求于2018年07月20日提交中国专利局、申请号为201810804698.0、申请名称为“一种系统恢复方法及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种系统恢复方法及装置。
背景技术
在电子设备(例如计算机等)在启动的过程中，由于该电子设备的原装系统损坏无法进入系统时，可以使用系统恢复出厂功能还原该电子设备的系统，进而顺利启动。
以计算机为例，通常计算机启动时，首先进行基本输入输出系统(basic input output system，BIOS)的启动，然后再进行操作系统(operating system，OS)的启动。目前，在计算机完成BIOS启动之后，由计算机的启动管理器和启动加载器进行OS启动，若计算机不能正常启动，则启动加载器将自动引导计算机进入系统恢复环境(例如WinRE，英文全称：windows recovery environment)，或者由用户手动按下相应的热键(例如F8键)，使得计算机进入系统恢复环境，实现计算机的系统恢复出厂设置。
然而，上述方法中，若计算机在OS启动之前发生故障，则计算机无法进入系统恢复环境，如此，导致计算机无法工作。
发明内容
本申请实施例提供一种系统恢复方法及装置，能够更加顺利地引导用户实现电子设备的系统恢复。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种系统恢复方法，应用于电子设备，该方法包括：在电子设备的BIOS启动阶段，获取电子设备的异常关机次数；若电子设备的异常关机次数大于或者等于预设阈值，则显示第一界面，该第一界面包括第一系统恢复机制选项；并且接收对第一系统恢复机制选项的选中操作，响应于对第一系统恢复机制选项的选中操作，运行第一系统恢复机制。
本申请实施例提供的系统恢复方法，由于在电子设备的启动过程中的BIOS启动阶段，在电子设备的异常关机次数大于或者等于预设阈值的情况下，可以引导用户按照需求选择系统恢复机制(例如上述的第一系统恢复机制)，从而使得该电子设备运行该系统恢复机制，如此，能够更加顺利地引导用户实现电子设备的系统恢复。
结合第一方面，在电子设备的异常关机次数大于或者等于预设阈值的情况下，设置系统恢复指示信息，该系统恢复指示信息用于指示电子设备显示第一界面。
结合第一方面，在电子设备的异常关机次数小于预设阈值的情况下，该电子设备按照正常的启动流程继续启动，具体的，该电子设备继续运行其他上电自检进程、加 载操作系统进程、操作系统回调ACPI进程、BIOS响应操作系统回调ACPI进程，并将异常关机次数增加1，然后再执行其他操作系统进程。
在第一方面的第一种可选的实现方式中，上述获取电子设备的异常关机次数之前，本申请实施例提供的系统恢复方法还包括：获取电子设备的高级启动指示信息，该高级启动指示信息用于指示电子设备运行第二系统恢复机制，本申请实施例中，系统还原标志的某一位可以定义为高级启动指示信息，该高级启动指示信息为1时指示电子设备运行第二系统恢复机制；高级启动指示信息为0时指示电子设备获取异常关机次数。
在第一方面的第二种可选的实现方式中，上述第一界面还包括下述至少一项:第二系统恢复机制选项、继续启动选项、关机重启选项。若电子设备的异常关机次数大于或者等于预设阈值，本申请实施例提供的系统恢复方法还包括：接收对第二系统恢复机制选项的选中操作；响应于对第二系统恢复机制选项的选中操作，运行第二系统恢复机制。本申请实施例中，第一界面可以包括多种选项，从而用户可以更加灵活地根据实际需求选择不同的选项，进而电子设备进行相应的响应。
在第一方面的第三种可选的实现方式中，本申请实施例提供的系统恢复方法还包括：在电子设备的BIOS启动阶段，若用户手动按下第一系统恢复热键，则电子设备显示第二界面，该第二界面包括第一系统恢复机制选项和关机重启选项；并且接收对第一系统恢复机制选项的选中操作，响应于对第一系统恢复机制选项的选中操作，运行第一系统恢复机制。本申请实施例中，在电子设备开机的过程中，电子设备可以自动引导电子设备进行系统恢复，而且用户也可以通过按下热键主动触发电子设备进行系统恢复。
在第一方面的第四种可选的实现方式中，本申请实施例提供的系统恢复方法还包括：在电子设备启动过程中，将异常关机次数增加1；在后续电子设备的运行过程中，若电子设备正常关机，则将异常关机次数清0，若电子设备异常关机，则异常关机次数不清零。本申请实施例中，在电子设备启动时将异常关机次数增加1之后，若电子设备后续发生异常关机，不将该异常关机次数清零，如此，在下次开机时，可以获取该异常关机次数，并根据异常关机次数确定是否对该电子设备进行系统恢复。
在第一方面的第五种可选的实现方式中，本申请实施例提供的系统恢复方法还包括：在电子设备的BIOS启动阶段，获取EC的状态，该EC的状态指示电子设备是否存在看门狗机制触发的关机事件；若电子设备存在看门狗机制触发的关机事件，将电子设备在BOIS启动阶段获取的异常关机次数减1。本申请实施例中，电子设备中的看门狗机制触发该电子设备关机时，此种关机现象实际上并不认为是异常关机，而认为是正常关机。然而，在电子设备的内部实现过程中，由于在看门狗机制触发电子设备关机时，上述异常关机次数也会增加1，并且电子设备的EC会记录(也可以理解为EC会感知)此事件(即由于看门狗机制触发的关机事件)，如此，在电子设备下一次启动的过程中，在BIOS启动阶段，会查询EC的状态，并且根据EC的状态确定电子设备存在看门狗触发的关机事件时，将获取到的异常关机次数减掉1，得到异常关机次数的真实值，并进一步判断是否对该电子设备进行系统恢复。
结合第一方面的第五种可选的实现方式，电子设备在休眠状态下看门狗机制触发 电子设备关机的事件，电子设备会将上述异常关机次数清0(即电子设备的异常关机次数不会发生累加)，并且EC对此种看门狗触发的关机事件不做记录(即EC不感知)。

本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一系统恢复机制和第二系统恢复机制等是用于区别不同的系统恢复机制，而不是用于描述系统恢复机制的特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。例如，多个处理单元是指两个或两个以上的处理单元；多个系统是指两个或两个以上的系统。
首先对本申请实施例提供的一种系统恢复方法及装置中涉及的一些概念做解释说明。
以电子设备为计算机为例，计算机的启动过程包括基本输入输出系统(BIOS)启 动和操作系统(OS)启动，计算机开机之后首先进行BIOS阶段的启动，完成BIOS启动之后，开始启动OS。
基本输入输出系统(BIOS)：是一组固化到计算机内主板上一个只读存储器(read only memory，ROM)芯片上的程序，它保存着计算机最重要的基本输入输出的程序、系统设置信息、开机后自检程序和系统自启动程序，其主要功能是为计算机提供最底层的、最直接的硬件设置和控制。
操作系统：是管理计算机硬件资源，控制其他程序运行并为用户提供交互操作界面的系统软件的集合。操作系统是计算机系统的关键组成部分，负责管理与配置内存、决定系统资源供需的优先次序、控制输入与输出设备、操作网络与管理文件系统等基本任务。操作系统的种类很多，各种设备安装的操作系统可从简单到复杂，可从手机的嵌入式操作系统到超级计算机的大型操作系统。常见的操作系统主要有Android、iOS、Linux、Windows、Mac OS X等。
异常关机：在Windows系统下，正常关机的关机流程需要执行三个步骤：软保护、硬保护，然后断电。其中，软保护指的是关闭用户的所有应用程序，保存用户的系统设置，停止系统服务；硬保护指的是停止硬件驱动程序；最后断电。
异常关机，即并未按照上述关机流程进行的关机现象，异常关机的场景可以包括用户手动强制关机或计算机发生蓝屏情况下的关机。具体的，用户手动强制关机的场景可以包括电子设备直接掉电关机(例如长按电源键掉电)，计算机发生蓝屏情况下的关机可以包括电子设备还未进入操作系统时发生异常，从而出现蓝屏等现象时，自动重启的流程。本申请实施例中，异常关机场景包含又不限于上面描述的这两个场景。
看门狗机制触发的关机：看门狗是一种保护机制，看门狗的工作原理实际上相当于一个定时器电路，在计算机中，处理器在一定的时间周期内输出一个信号到看门狗的输入端(即喂狗端)，使得看门狗电路清零，如果在规定的时间周期内没有输出信号至看门狗，看门狗会产生一个系统复位，即关闭计算机并重新启动。总的来说，看门狗可以防止程序无限制的运行，造成死循环，或者程序跑飞。
基于背景技术存在的问题，本申请实施例提供一种系统恢复方法及装置，可以在电子设备的BIOS启动阶段，获取该电子设备的异常关机次数；并且在电子设备的异常关机次数大于或者等于预设阈值，显示包括第一系统恢复机制选项的第一界面；以及接收对该第一系统恢复机制选项的选中操作；响应于对该第一系统恢复机制选项的选中操作，运行第一系统恢复机制，从而实现电子设备的系统恢复。
本申请实施例提供的电子设备可以为具有操作系统的电子设备，例如该电子设备可以为计算机(例如台式电脑、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)等)、手机、上网本或者个人数字助理(personal digital assistant，PDA)、智能汽车、传感设备、物联网(internet of thing，IOT)设备、客户终端设备(customer premise equipment，CPE)等。
示例性的，以电子设备为计算机为例介绍电子设备的硬件结构。如图1所示，本申请实施例提供的计算机包括处理器10、存储器11、输入设备12、输出设备13等部件。本领域技术人员可以理解，图1中示出的计算机的结构并不构成对计算机的限定，其可以包括比如图1所示的部件更多或更少的部件，或者可以组合如图1所示的部件 中的某些部件，或者可以与如图1所示的部件布置不同。
处理器10：是计算机的核心部件，处理器10可以中央处理器(central processing unit，CPU)，在微型计算机(简称微机或个人计算机)中，CPU又称为微处理器。处理器主要由控制器101和运算器102组成。
其中，控制器101是计算机中指令的解释和执行结构，其主要功能是控制运算器102、存储器11、输入设备12、输出设备13等部件协调动作。控制器101工作时，从存储器11取出一条指令，并指出下一条指令所在的存放地址，然后对所取指令进行分析，同时产生相应的控制信号，并由控制信号启动有关部件，使这些部件完成指令所规定的操作。这样逐一执行一系列指令组成的程序，就能使计算机按照程序的要求，自动完成预定的任务。
运算器102的主要功能是完成对数据的算术运算、逻辑运算和逻辑判断等操作。在控制器101控制下，运算器102对取自存储器11或其内部寄存器的数据按指令码的规定进行相应的运算，并将结果暂存在内部寄存器或送到存储器11中。
存储器11：是用来存储程序和数据的部件，是计算机的重要组成部分。存储器11可以包括内存111和硬盘112。其中，内存是内存储器的简称，内存111由高速的半导体存储器芯片组成，是计算机运行过程中临时存放程序和数据的地方。计算机运行过程中，将待处理的数据，先从硬盘112调入内存111，再从内存111调入处理器10；处理器10处理完毕后，将数据送到内存111，最后保存到硬盘112。
内存111可以包括随机存取存储器(random access memory，RAM)、ROM、高速缓冲存储器(Cache)。RAM中的数据可随机地读出或写入，是用来存放从硬盘112调入的程序和有关数据以及从处理器10送出的数据，通常所说的内存实际上指的是RAM。需要指出的是，计算机断电后，RAM中的数据将完全丢失。ROM占内存的很小一部分，ROM中通常存放的是一些固定的、专用程序或数据，处理器10对ROM仅进行读取。Cache的存储容量比较小，但速度比RAM高得多，接近于CPU的速度，Cache在计算机存储系统的层次结构中，是介于CPU和RAM之间的高速小容量存储器。
输入设备12：用于向计算机输入程序和所需处理的原始数据(包括文本、图形、图像、声音等)，计算机上的输入设备12可以包括键盘121、鼠标122。键盘121键盘是计算机中最基本的输入设备，键盘上排列了字母、数字、符号键等，通过按键操作，可把命令、程序和数据等信息输入到计算机中。鼠标122是计算机中的辅助输入设备，鼠标122是一种指点“设备”，表面有2个或3个按键，通过鼠标可对操作对象进行单击、双击、拖动等操作。鼠标122可以包括有线鼠标和无线鼠标。
可选的，计算机的输入设备131还可以包括扫描仪、手写板等。
输出设备13：用于输出计算机的运行或数据处理结果。输出设备13可以包括显示器131，显示器131是计算机最基本的输出设备，也是人机对话的主要工具。计算机通过显示器用户提供各种应用软件的操作界面，用户可以通过这些界面输入数据、选择各种功能、获知程序运行的结果等。
显示器131可以为触摸显示器，该显示器131包括显示面板和触摸屏。可选的，可以采用液晶显示器(liquid crystal display，LCD)、有机发光二极管(organic light-emitting diode，OLED)等形式来配置显示面板。进一步的，触摸屏可覆盖显 示面板，当触摸屏检测到在其上或附近的触摸操作后，传送给处理器10以确定触摸事件的类型，随后处理器10根据触摸事件的类型在显示面板上提供相应的视觉输出。触摸屏与显示面板是作为两个独立的部件来实现计算机的输入和输出功能，但是在某些实施例中，可以将触摸屏与显示面板集成而实现计算机的输入和输出功能。
可选的，上述输出设备13还可以包括打印机、绘图仪等。
可选的，本申请实施例提供的计算机还可以包括调制解调器、风扇、电源、网卡、声卡、Wi-Fi模块、蓝牙模块等。
本申请实施例提供的计算机还包括软件系统，包括系统软件和应用软件，系统软件包括操作系统(OS)。
基于上述对电子设备的各个构成部件的描述，本申请实施例提供一种系统恢复方法，如图2所示，该方法可以包括S101-S104:
S101、在电子设备的BIOS启动阶段，获取该电子设备的异常关机次数。
其中，上述电子设备的异常关机包括下述至少一项：强制关机、电子设备发生蓝屏后关机。该电子设备的异常关机还可以包括其他导致电子设备关机的现象，本申请实施例不作具体限定。
本申请实施例中，在BIOS的内存空间中，将BIOS中的闪存中的一个字节(即8位比特)的存储空间用于存储用于与电子设备的系统恢复方法有关的指示信息(或者可以理解为标志位)，可以称为系统还原标志，下述实施例中，将该系统还原标志记为BIOS Flash Flag。具体的，可以将BIOS Flash Flag中的某些位用于指示异常关机次数，如此，在电子设备开机过程中，在BIOS启动阶段，通过读取BIOS Flash Flag中的对应的比特，从而得到该电子设备的异常关机次数。
示例性的，如图3所示，对于上述BIOS Flash Flag，按照从右向左的方向，将BIOS Flash Flag的前3位(即低3位)用于指示异常关机次数，记为Flag[3:0]。上述BIOS Flash Flag的低3位比特所表示的二进制数可以为异常关机次数，示例性的，如下表1为BIOS Flash Flag的低3位比特的取值与异常关机次数之间的关系示例。
表1
低3位比特的取值 异常关机次数
000 0
001 1
010 2
011 3
100 4
101 5
110 6
111 7
需要说明的是，本申请实施例中，上述异常关机次数是一个累加值。具体的，在电子设备启动过程中，BOIS完成启动，并且操作系统加载完成之后，操作系统可以回调高级配置和电源管理接口(advanced configuration and power interface，ACPI)，操作系统通过回调ACPI以获得对电子设备的管理权限，从而BIOS响应于该操作系统 对ACPI的回调，将对电子设备的管理权限移交至操作系统，并且BIOS将异常关机次数增加1，即将BIOS Flash Flag中的低3位的值增加1；在后续电子设备的运行过程中，若该电子设备正常关机，则将异常关机次数清0；若电子设备异常关机，则异常关机次数不清零，在这种情况下，可见在电子设备发生异常关机时，电子设备的异常关机次数会累加。
S102、若电子设备的异常关机次数大于或者等于预设阈值，则该电子设备显示第一界面，该第一界面包括第一系统恢复机制选项。
本申请实施例中，上述第一系统恢复机制选项对应的是第一系统恢复机制，该第一系统恢复机制可以为原始设备制造商(original equipment manufacturer，OEM)自定义的系统恢复机制。
需要说明的是，上述预设阈值可以根据实际使用需求设置(例如设置为3次)，本申请实施例不作具体限定。
S103、电子设备接收对第一系统恢复机制选项的选中操作。
本申请实施例中，电子设备的显示屏为触摸屏时，上述对第一系统恢复机制的选中操可以为通过手指触发或触控笔触发的对电子设备的触控屏的按压操作、长按操作、滑动操作、点击操作、悬浮操作(用户在触控屏附近的操作)等。
可选的，上述对第一系统恢复机制选项的选中操作也可以为按键操作，例如按键操作对应于对电子设备的电源键、音量键、键盘上的Enter键等按键的单击操作、双击操作、长按操作、组合按键操作等操作。
S104、电子设备响应于对第一系统恢复机制选项的选中操作，运行第一系统恢复机制。
本申请实施例中，上述电子设备运行第一系统恢复机制即指的是电子设备运行第一系统恢复机制对应的系统恢复程序，使得电子设备的系统恢复成出厂设置的状态。
示例性的，以电子设备为计算机为例，如图4所示，当计算机的异常关机次数大于或者等于预设阈值(例如3次)时，计算机显示第一界面200，在该第一界面200中包括第一系统恢复机制选项201，用户可以选中(例如点击)该第一系统恢复机制选项201，从而计算机进行相应的响应。
本申请实施例提供的系统恢复方法，由于在电子设备的启动过程中的BIOS启动阶段，在电子设备的异常关机次数大于或者等于预设阈值的情况下，可以引导用户按照需求选择系统恢复机制(例如上述的第一系统恢复机制)，从而使得该电子设备运行该系统恢复机制，如此，能够更加顺利地引导用户实现电子设备的系统恢复。
下面从电子设备的完整的启动过程详细介绍本申请实施例提供的系统恢复方法，如图5所示，该方法可以包括：
S201、上电自检。
S202、处理上电自检进程。
本申请实施例中，电子设备开始启动(例如用户按下开启按钮)时，首先进行BIOS的启动，即电子设备开始自检。
S203、检测用户是否按下热键。
本申请实施例中，在电子设备的开机过程中，检测到用户按下某一热键(例如F8 或F10等)相当于向电子设备输入了某一指令，然后电子设备会响应于该指令，执行对应的操作。
示例性的，用户按下热键F8时，可以执行下述S204a：
S204a、用户按下热键F8，电子设备执行第二系统恢复机制。
本申请实施例中，在电子设备开机过程中，按下热键F8对应的操作是电子设备执行第二系统恢复机制，实现系统恢复。
上述第二系统恢复机制可以为Windows默认的系统恢复机制(可以简称为WinRE)，该第二系统恢复机制也可以为其他类型的系统恢复机制，本申请实施例不作具体限定。
可选的，本申请实施例中，上述电子设备进入第二系统恢复机制，完成电子设备的系统恢复之后，若该电子设备可以正常关机，则将异常关机次数清零，即将上述BOIS Flash Flag中的低3为比特复位，例如，若“0”表示复位，则将BIOS Flash Flag的低3位比特均清零。
用户按下热键F10时，可以执行下述S204b：
S204b、用户按下热键F10，电子设备执行第一系统恢复机制。
本申请实施例中，在电子设备开机过程中，按下热键F10对应的操作是电子设备执行第一系统恢复机制，实现系统恢复。其中，第一系统恢复机制与上述第二系统恢复机制不同，例如该第一系统恢复机制可以为OEM自定义的系统恢复机制。
同理，可选的，本申请实施例中，上述电子设备进入第一系统恢复机制，完成电子设备的系统恢复之后，若该电子设备可以正常关机，则将异常关机次数清零，即该电子设备将上述BOIS Flash Flag中低3位比特清零。
上述S204a或S204b中电子设备进行系统恢复均是用户主动操作的结果，并非电子设备自动(或自发)地引导用户进行选择的结果。
用户按下热键F12时，可以执行下述S204c：
S204c、用户按下热键F12，电子设备显示系统引导界面。
本申请实施例中，用户按下热键F12之后，电子设备可以显示系统引导界面，从而用户可以在该引导界面上进行相关操作，进入指定的系统。
用户按下热键F2时，可以执行下述S204d：
S204d、用户按下热键F2，电子设备显示BIOS设置界面。
本申请实施例中，用户按下热键F2之后，电子设备可以显示BIOS设置界面，从而可以在该界面上设置BIOS的一些开关。
本申请实施例中，若检测用户未按下任何热键，则执行下述S205以及后续的相关步骤：
S205、获取电子设备的高级启动指示信息。
其中，上述高级启动指示信息指示电子设备运行第二系统恢复机制。
本申请实施例中，如图3所示，可以将上述BIOS Flash Flag的第5位(按照从右到左的方向)定义为高级启动指示信息，记为Flag[5]。上述获取电子设备的高级启动指示信息具体包括：在BIOS启动阶段，读取BOIS Flash Flag的第5位，即Flag[5]。
可选的，本申请实施例中，可以采用标识“1”来指示电子设备运行第二系统恢复机制，也可以采用标识“0”来指示电子设备运行第二系统恢复机制，具体可以根据实 际使用需求选择，本申请实施例不作限定。
示例性的，如果上述高级启动指示信息为1时指示电子设备运行第二系统恢复机制，那么高级启动指示信息为0时指示电子设备获取异常关机次数，如下表2为高级启动指示信息与其指示的含义之间的关系的一种示例。
表2
高级启动指示信息 含义
1 运行第二系统恢复机制
0 获取异常关机次数
如图5所示，本申请实施例中，若上述高级启动指示信息为“1”，该电子设备运行上述第二系统恢复机制(即WinRE)，若上述高级启动指示信息为“0”，执行下述S206：
S206、获取电子设备的异常关机次数。
本申请实施例中，在BIOS启动阶段，读取BOIS Flash Flag中的低3位比特，即Flag[3:0]，结合上述S101中的表1可知电子设备的异常关机次数。
需要强调的是，本申请实施例中，在电子设备的BIOS启动阶段，可以获取嵌入式控制器(embedded controller，EC)的状态，该EC的状态指示该电子设备是否存在看门狗机制触发的关机事件。
若电子设备存在看门狗机制触发的关机事件，将该电子设备在BIOS启动阶段获取的异常关机次数减1，得到新的异常关机次数，然后再根据新的异常关机次数确定该电子设备是否需要进行系统恢复。若该电子设备不存在看门狗机制触发的关机事件，则直接根据获取的异常关机次数确定该电子设备是否需要进行系统恢复。
本申请实施例中，电子设备中的看门狗机制触发该电子设备关机时，此种关机现象实际上并不认为是异常关机，而认为是正常关机。然而，在电子设备的内部实现过程中，由于在看门狗机制触发电子设备关机时，上述异常关机次数也会增加1，并且电子设备的EC会记录(也可以理解为EC会感知)此事件(即由于看门狗机制触发的关机事件)，如此，在电子设备下一次启动的过程中，在BIOS启动阶段，会查询EC的状态，并且根据EC的状态确定电子设备存在看门狗触发的关机事件时，将获取到的异常关机次数减掉1，得到异常关机次数的真实值。
需要说明的是，电子设备在休眠状态下看门狗机制触发电子设备关机的事件，电子设备会将上述异常关机次数清0(即电子设备的异常关机次数不会发生累加)，并且EC对此种看门狗触发的关机事件不做记录(即EC不感知)。
S207、电子设备确定该异常关机次数是否大于或者等于预设阈值。
一种实现方式中，在电子设备的异常关机次数小于预设阈值的情况下，该电子设备按照正常的启动流程继续启动，如图5所示，该电子设备继续运行其他上电自检进程、加载操作系统进程、操作系统回调ACPI进程、BIOS响应操作系统回调ACPI进程，并将异常关机次数增加1(具体的，在上述异常关机次数小于或者等于15的情况下，将该异常关机次数增加1)，然后再执行其他操作系统进程。
结合上述S101中的相关描述，电子设备后续运行过程中，若电子设备正常关机，则将上述异常关机次数清零，若电子设备异常关机，则上述异常关机次数值不清零， 即异常关机次数会累加。
另一种实现方式中，在电子设备的异常关机次数大于或者等于预设阈值的情况下，设置系统恢复指示信息，该系统恢复指示信息用于指示电子设备显示第一界面。
本申请实施例中，如图3所示，可以将BIOS Flash Flag的第4位(按照从右到左的方向)定义为系统恢复指示信息，记为Flag[4]。该系统恢复指示信息用于指示电子设备显示第一界面，从而用户可以根据需求在第一界面上进行相应的操作，从而电子设备做出不同的响应。
可选的，如图3所示，可以将该BIOS Flash Flag中的其他比特(如高3位比特)作为预留比特。
可选的，本申请实施例中，可以采用标识“1”来指示电子设备显示第一界面，也可以采用标识“0”来指示电子设备显示第一界面，具体可以根据实际使用需求选择，本申请实施例不作限定。
示例性的，如果上述系统恢复指示信息为“1”，那么指示电子设备显示第一界面；如果系统恢复指示信息为“0”，那么指示电子设备显示第二界面，该第一界面与第二界面不同。如下表3为系统恢复指示信息与其指示的含义之间的关系的一种示例。
表3
系统恢复指示信息 含义
1 显示第一界面
0 显示第二界面
需要说明的是，本申请实施例中，上述确定电子设备的异常关机次数是否大于或者等于预设阈值的动作是BIOS内部的一个动作，在BIOS确定异常关机次数是否大于或者等于预设阈值时，需要将此事件通知给还原应用，因此电子设备设置系统恢复指示信息(例如将Flag[4]设置为1)，从而还原应用根据该系统恢复指示信息，运行OEM自定义的系统恢复机制。具体的实现方式是：将该电子设备的系统。
本申请实施例中，上述电子设备的异常关机次数大于或者等于预设阈值的情况下，设置该电子设备的系统恢复指示信息之后，继续执行下述S208：
S208、获取电子设备的系统恢复指示信息。
本申请实施例中，在BIOS启动阶段，获取系统恢复指示信息具体包括：读取BOIS Flash Flag中的第4位(从右向左)，即Flag[4]。
对于系统恢复指示信息的描述，可以参将上述S207中关于系统恢复指示信息的详细描述，此处不再赘述。
本申请实施例中，以系统恢复指示信息为1指示电子设备显示第一界面，以系统恢复指示信息为0指示电子设备显示第二界面为例，若系统恢复指示信息为1，则执行S209等相关步骤。
S209、电子设备显示第一界面，该第一界面包括第一系统恢复机制选项。
可选的，本申请实施例中，上述第一界面还可以包括下述选项中的至少一项：第二系统恢复机制选项、继续启动选项、关机重启选项。电子设备显示第一界面，并且第一界面上显示不同的选项，用户可以在第一界面上进行相关的操作，即根据需求选择某一个选项的操作。
示例性的，以电子设备为计算机为例，并且以第一界面包括第一系统恢复机制选项、第二系统恢复机制选项、继续启动选项以及关机重启选项为例，如图6所示，当计算机的异常关机次数大于或者等于预设阈值(例如3次)时，计算机显示第一界面300，在该第一界面300中包括第一系统恢复机制选项301，第二系统恢复机制选项302，继续启动选项303以及关机重启选项304，用户可以根据需求选中(例如点击)上述四个选项中的任意一个(例如选中第二系统恢复机制选项302)。
若用户选中第一系统恢复机制选项，则执行下述S2101a-S2101b：
S2101a、电子设备接收对第一系统恢复机制选项的选中操作。
S2011b、电子设备响应于对第一系统恢复机制选项的选中操作，运行第一系统恢复机制。
需要说明的是，本申请实施例中，电子设备执行S2101a-S2101b，电子设备完成系统恢复，在后续电子设备的运动过程中，若电子设备正常关机，并且将上述BIOS Flash Flag的低3位比特(包括Flag[3:0])复位，即清零。
对于S2101a-S2101b的其他描述，可以参见上述S103-S104的相关描述，此处不再赘述。
若用户选中第二系统恢复机制选项，则执行下述S2102a-S2102c：
S2102a、电子设备接收对第二系统恢复机制选项的选中操作。
S2102b、电子设备响应于对第二系统恢复机制选项的选中操作，运行第二系统恢复机制。
本申请实施例中，电子设备响应于对第二系统恢复机制选项的选中操作,运行第二系统恢复机制具体包括：电子设备设置电子设备的高级启动指示信息(例如将Flag[5]设置为1)，然后电子设备重新启动，即电子设备重新执行上述S201开始的各个步骤，可以理解的是，当电子设备执行到上述S205时，即获取高级启动指示信息时，由于在重新启动前已经将该高级启动指示信息设置为1，如此，电子设备在该高级启动指示信息的指示下运行第二系统恢复机制，实现电子设备的系统恢复。
同理，电子设备执行第二系统恢复机制，完成系统恢复，在后续电子设备的运动过程中，若电子设备正常关机，该电子设备将上述BOIS Flash Flag中的低3位比特复位，即清零。
本申请实施例中，上述第一系统恢复机制为OEM自定义的系统恢复机制，上述第二系统恢复机制为Windows默认的系统恢复机制，相比于Windows默认的系统恢复选项，采用OEM自定义的系统恢复机制进行系统恢复具有速度快、通用性好的优点。
若用户选中继续启动选项，则执行下述S2103a-S2103b：
S2103a、电子设备接收对继续启动选项的选中操作。
S2103b、电子设备响应于对继续启动选项的选中操作，继续启动。
本申请实施例中，电子设备继续启动指的是电子设备按照正常的启动流程继续启动，具体可以参见上述S207中的相关描述。该电子设备继续启动时，该电子设备可能会顺利启动，该电子设备也可能无法顺利启动。
若用户选中关机重启选项，则执行下述S2104a-S2104b：
S2104a、电子设备接收对关机重启选项的选中操作。
S2104b、电子设备响应于对关机重启选项的选中操作，关机后再重新启动。
本申请实施例中，电子设备关机时，若电子设备正常关机，则将上述BIOS Flash Flag中的低3位(即包括Flag[3:0])复位，即清零。电子设备关机后再重新启动即电子设备重新开始执行上述S201开始的各个动作。
可选的，上述在电子设备的BIOS启动阶段，若用户手动按下第一系统恢复热键(即F10热键)，则该电子设备还需要执行上述S208(获取该电子设备的系统恢复指示信息)。
本申请实施例中，若系统恢复指示信息为0，执行S211等相关步骤。
S211、电子设备显示第二界面，该第二界面包括第一系统恢复机制选项和关机重启选项。
上述电子设备显示第二界面，用户可以在第二界面上进行相关的操作，即根据需求选择某一个选项的操作。
