    As a postgraduate student, I often have tasks that require me to process a large amount of data which takes over 5 hours on MATLAB. So I just begin my task,  lock my computer and do something else. But when I unlock my computer about 3 hours later, it becomes so slow, and sometimes my screen just turns black after I enter my password.
    My computer is Acer E5-552G-F41L, with AMD FX-8800P(Quadcore CPU) and 8 GB RAM, running Deepin 15.3.

    Hi,
    It could be the msr register 0x19a is not set back to 0 after resume. Try to set it to 0 by installing msr-tools and run wrmsr 0x19a 0x0.
    sudo apt-get install msr-tools
    sudo modprobe msr
    sudo rdmsr -a 0x19a
    if rdmsr does not give back 0 then:
    sudo wrmsr -a 0x19a 0x0

    good luck
