Рандомное выключение ноутбука (ThinkPad T430u)

[1amer]

Пытаюсь разобраться в проблеме и выяснить виновато железо или ОСь. Ноут ThinkPad T430u. Ubuntu 14.10 х64 была установлена с нуля на жесткий диск. На диске только Ubuntu, весь диск был зашифрован LUKS'ом при установке. Так же в биосе включен чип TPM.

Проблема: Рандомно выключается ноут. Первый раз выключился после установки Убунты и нескольких часов работы (в syslog ниже этого нету). Второй раз выключился, когда выходил из режима сна, при открытии крышки (в syslog ниже есть этот момент). Третий раз выключился, после нескольких часов работы (в syslog ниже есть этот момент). Во втором syslog последние секунды жизни была инфа про температуру графики.

Куда копать?

Второе выключение ноута, при выходе из режима сна. В syslog есть только то, что было перед сном.

1. попробуйте установить\сменить драйвер видеокарты;
2. отнесите ноут в чистку, пускай вскроют, вычистят систему охлаждения от пыли, заменят термопасту и\или термопрокладки.

Я так и думал, что это скорее всего виновата графика.
Спасибо.
