I have a laptop Inspiron N5110.I recently noticed that after the top being pulled up (after a standby process), my cursor sometime freezes on the screen lock window.Do you think this is a serious issue?Several months ago I dropped my laptop but until now this issue hadn't appeared.I would be glad if you can help me.Thanks.
