my lenovo laptop will not log in as cursor will not move

I have read quite a few other threads about stuck cursors, none of which have helped. When I turn my computer on, whether normally or safe mode I am unable to move the cursor to log in. A lot of threads suggest downloading software or trying various websites.
None of that can be performed if I can't log in.

Are there any suggestions which will get the cursor to move so I can login. I have most of the files backed up, but there is one I was using for work earlier that I was working on when it froze. I'd like to be able to get it back and use the laptop as before.

 

Laptop cursor moves but will not click on anything

Hi. My laptop cursor suddenly doesn’t click on anything as it should. It moves perfectly as usual but will not click on anything in the laptop menu or on pictures etc- anything. Also, when I move the cursor it draws a kind of box shape the size of which changes depending upon how far I move the cursor. Can anyone here help? Thank you.

 

cursor dissappeared

Thank you both for your prompt replies, I tried all steps listed, some I had tries previously but I still tried them again, but still no cursor.

Do you have any other suggestions?
