How to clean up your computer before you sell it

I went to a huge garage sale this morning. I walked home with a 7-year-old Dell 15" LCD monitor. What I paid for it wouldn’t buy lunch for my wife and me. When I got it home and saw how well it worked, I felt guilty.

So if you’re thinking of selling some computer equipment, take my tips (as someone who attends literally thousands of garage sales every year) for getting decent money for it.The main reason I got this monitor for so little is because it looked like it sat in a dusty garage or attic for several years. It was filthy. I’ve seen identical monitors sell for 50 bucks as recently as June. Identical except for the dirt, that is.

I cleaned the monitor up using nothing more than an old dish towel and some all-surface biodegradable cleaner I buy at Costco. But dish detergent would work in a pinch. Dampen the towel, wring it out, add a bit of cleaner, and clean all the surfaces except for the screen. You’ll get more money if it looks like the unit was taken care of. You want it to look like you just bought its replacement yesterday.

You’ll also get more if you can demonstrate it works. Run an extension cable or two if necessary, and hook the stuff up so shoppers can see it in action. Many shoppers assume bargain-priced computer equipment at garage sales doesn’t work. In my experience, about half of it does. So I pay accordingly.

Finally, price realistically. These are the same people who get up at 4am the day after Thanksgiving to wait in line until Office Depot opens. I know because I do that too, and I see the same people I see every Saturday. So you’re competing with Black Friday’s prices, with used equipment.

That said, a working computer that runs Windows XP decently (and has a legal copy of XP on it) should fetch $75-$100, depending on its speed. A 1 GHz PC will run closer to $75, while a 2 GHz PC will fetch $100. And at that price, it should sell fairly quickly.

If a computer is decent but doesn’t work, it won’t sell for much. I’ve paid $10 for computers that need hard drives before, and I’ve passed on $10 computers that need hard drives. Sometimes I regret not buying that Pentium 4 that worked except for the hard drive, but my back hurt that day and I didn’t feel like lugging it home.

CRT monitors are hard to give away these days, but if you can demonstrate it works and it looks presentable, a 17-inch monitor is worth $10-$20. Your best bet for getting rid of one of those, though, is to bundle it with a working computer that runs Windows XP.

A working 15-inch LCD monitor should sell for $50 without any trouble.

Keyboards and mice are giveaways. I literally wish I had a dollar for every time someone’s tried to give me a keyboard. Anyone who wants one already has too many. The lone exception to this rule is an optical mouse. But a new, mid-range Microsoft optical mouse sells for $20-$25 on sale, so don’t expect to get more than $5-$10 for one. I paid $2 for one this year, and it didn’t work. I was willing to take a chance at that price, but no higher.
