Replacement Laptop Batteries

I had Outlook Express on my Compaq Presario that ran under Windows XP that I used for my emails. I got a new Toshiba laptop and I can't fine OE on it. What does Toshiba use for email software? Do I need to install another software application?

I have a new Sony Vaio and an HDMI cable and I'd like to connect it to my Mitsubishi Hi-Def 1080 TV set. However, the Mitsubishi gives me an error message saying it doesn't recognize the signal. What should I do? I'm trying to use the TV as a monitor for gaming.
