Top Stories laptops
Dear Lifehacker, I’m going to be travelling soon and I need to take my laptop with me. How can I make sure it’s as safe as possible? I won’t always have my own desk, and sometimes I’ll have to work from public places. How can I protect my laptop and the data that’s on it when I use it away from home?

Dear Lifehacker, I have a laptop — it’s not too old — and I love it, but I’m thinking I could use a bigger hard drive, or maybe some more RAM.

How can I find out whether I can upgrade it before I crack it open?
