Cannot wake up from sleep

Clear Linux is my first attempt as using any form of Linux, so all information about Linux processes are new to me. When my laptop goes to sleep (either through closing the laptop of letting it time out) I am having problems waking it up. When I go to wake up the laptop all I see is a black screen with one white underscore in the top left corner. I have clicked enter, space bar, ctr alt delete, esc, etc. Is there a way I need to wake up the laptop in Linux? Or is there something that I can do to fix this issue? Currently the only way I can bring up the computer is to hold the power button until the laptop fully turns off.
