Why are my keys not responding when computer wakes up?

Whenever I close the lid on my computer some of my keys stop working.

For example the E, R, O, CMD and others.

What confuses me is that if I squeeze the keys really hard (like smashing them with all my strength) they work sometimes. Has anyone else experienced this problem? Does this mean I should replace my keyboard?

I don’t mind replacing the keyboard since I’m good at fixing electronics but just want to make sure its not a software issue. Because eventually they start working perfectly after a while of trying (like 5 min) to smash them until the computer goes to sleep.
