How to access Team Viewer from other place?

Hello,
So as i am working girl, as there are some work in pending, so i decided to use team viewer from home and connect it to company pc to work, both home and company pc have Team viewer 10, so i create password and note it and let my company computer lock (without shutdown) press windows+L key before i going to home.....
but when i try to access from home it shows team viewer is not running in partner computer....
I dont know the power shutdown in my company at the time of i accessing the team viewer....
My question is
1) To access from home i need to leave the pc as it is (switch on with logged in)
2) Whether i have to put team viewer in startup?
3) without internet connection in home or office team viewer does not work?
Thank you for reading..
Hope good replies from you guys...:blink:

You need to keep your pc turned on and then create a manual password and login id in the same pc. After that when ever you want to access the that pc from anywhere, simply use the password and login id that you have created manually to access that pc remotely.
