When I logged in through my PC facebook keeps me online even if turn off the chat?

Here's some ideas I hope it'll work to solve your problem:

1) Create at least one list of friends, if you don't have any lists yet (Friends -> Create a list). You don't need to put all your friends into it, just make sure you have at least one list.

2) Open the chat window and use the small slider button that is located right of each group name to set your visibility to "offline" for each group.

Done! Now you seem to be offline for all of your friends, even after you log out and in again , even though your status is displayed "online" (green circle in the chat window). To use the chat again, simply open the chat window and toggle the slider buttons as you did in step 2.

Thankyou
