Dealing with a laptop spill

Q. I recently spilled coffee on my laptop's keyboard and fried it. Since I'm a klutz, what should I do if this happens again?

A. Consider picking up an ultra-thin transparent silicon keyboard protector skin for your laptop. It will protect against spills, wear and tear, dirt, food crumbs, bugs and other unwanted stuff. If a spill does occur again, immediately turn the laptop upside down, disconnect the power cord and remove the battery. Let it sit for at least 24 hours so that the coffee can drain and dry. With something sticky like coffee, you may need to remove the keyboard keys to really clean it out. Click here for more details on recovering from a spill.

Ignoring a chatty Kathy

Q. Whenever I get on Facebook, my sister pops up in the Facebook chat window and wants to talk. I love her, but sometimes I just don't have the time. Is there a way to use Facebook without letting her know I'm on?

Know where the kids hang out online

Q. I follow my 13-year-old son's account on Facebook, but he doesn't seem to be posting much for all the time he spends on his phone. Is there a site I'm missing that he might be using?

A. Kids are moving off Facebook for this reason, and there are plenty of alternatives. Just about every teen has an Instagram account. The blogging site Tumblr is popular and so are the question-and-answer site Ask.fm and secret-sharing site Whisper. These sites can be dangerous to kids due to inappropriate content and creepy strangers. You need to get on your son's phone to see the sites and apps he's using and what he's posting.

What is two-step verification?

Q. I was poking around in my Facebook settings and I saw something called Login Approvals. Is that a good thing to turn on?

A. Login Approvals is Facebook's version of two-step verification, also called two-factor authentication. It means that to log into an account from an unknown computer, you need two forms of ID. One is usually your password and the second is a special code sent to your cellphone or another email address. Even if a hacker gets your password, they probably won't have access to your phone or email account to get the special code. Google, Microsoft and many banks offer two-step verification. It's a great first step to take to protect your online accounts. Click here for four more ways to keep your accounts safe from hackers.
