I got myself a T400 and it didn't come with a user's manual. The only thing I could find online was the ThinkPad T400 and R400 Hardware Maintenance Manual. This doesn't seem like a user's manual teaching how to use the laptop, but more of a technical manual. Is there an user's manual?

Thanks!

The HMM could be considered the users manual and I don't think there is a specific users manual. The HMM covers a lot of ground. Is there something you wanted to know?

Maybe this one here:

Just the normal stuff, like how long to charge the battery and things like that. Also this is my first Thinkpad so I don't know how to use the fingerprint reader, camera, and even the keyboard light. Just a user's guide would be nice.

Will look at that, thanks. But it seems also to be a technical document.

Well the first two depend on your operating system, so you might want to consult your OS's documentation. The last one is simple: Fn + the the key with the picture of a light in the top right corner of your keyboard. Given that it's a light, there's really not much more than "on" and "off".
