Strangely enough, I have just what you need at home…

A word to the wise for people who buy brand-new laptop computers on the street for $400.00:

If you want a power adapter for it, buy it online or write down the model number of the computer, then go shopping.

Don’t take the computer into the store with you.

Especially if it has someone else’s name written on the case.

And as a last resort, look carefully at the clerk’s name tag when you ask for help.
