我有一台华硕 R558U 笔记本电脑（硬件详情见本文底部）。几个月前，它在随机情况下开始完全冻结。最近我决定更仔细地观察它，并尝试不同的硬件和软件配置，以排除一些可能性。但我看不出任何规律。我已经搜索并阅读了许多文章来寻找解决方案，但都没有成功。
频率： 每隔几天一次，我认为随着时间的推移，这种情况有所增加
症状：
- 笔记本电脑完全冻结（总是）
- 奇怪的嗡嗡声（有时）
- 图形伪影（有时）
在以下操作系统上可见（我使用双启动）：
- Ubuntu 17.10
- Ubuntu 16.04
- Windows 10
在以下活动期间：
- 在看电影
- 互联网浏览
- 图像编辑
- 编程
- 即使闲置
以下是我已经尝试并检查过的：
温度 - 似乎不是问题。这是我在冻结后立即重新启动时收集的传感器程序的输出：
coretemp-isa-0000 Adapter: ISA adapter Package id 0: +49.0°C (high = +100.0°C, crit = +100.0°C) Core 0: +48.0°C (high = +100.0°C, crit = +100.0°C) Core 1: +48.0°C (high = +100.0°C, crit = +100.0°C) acpitz-virtual-0 Adapter: Virtual device temp1: +48.0°C (crit = +103.0°C) asus-isa-0000 Adapter: ISA adapter cpu_fan: 3500 RPM temp1: +48.0°C pch_skylake-virtual-0 Adapter: Virtual device temp1: +47.5°C磁盘实用程序的智能数据和自检 - 一切正常
- memtest86-一切正常
当我观察到问题时，我的外围设备和无线适配器：
- wifi 一直开着
- USB 远程键盘 + 鼠标始终处于插入状态（尝试过不同的 USB 端口）
- 蓝牙打开或关闭
- 外接显示器已插入或已拔出（vga 电缆）
- USB 驱动器已插入或拔出
- 电源线已插入或拔出
- 耳机插入或拔出
