When comparing refurbished laptop models, ask about these specs:
Central Processing Unit: The CPU or processor is the heart of the computer. The more software you want on your refurbished laptop, the more powerful the processor needs to be. A 32-bit processor is less powerful and less expensive than a 64-bit processor.
Operating System: The operating system, or OS, is the graphical interface between you and whatever programs you’re running. Windows and Unix are the two main families of operating systems. Windows is the most common interface and therefore the least expensive.
Screen size: Smaller doesn’t necessarily mean cheaper; some smaller models are just as powerful as some larger but more portable models.
Hard Drive Size: The hard drive, or HD, is the permanent storage disk inside the drive. HD capacity is measured in gigabytes. A GB is one billion bytes. A byte is a piece of information, such as text, sound, or image. The bigger the hard drive, the more software it can handle, and the more expensive the laptop will be.
Hard Drive Speed – Hard drive speed is measured in revolutions per minute, typically 5,000 to 15,000 RPM. The faster the HD, the better and more expensive the laptop.
Random Access Memory – RAM is the temporary storage chip that continually updates information while you use your computer. Today, 64 megabytes is the basic size of RAM, adequate to run many programs simultaneously. The greater the storage capacity of RAM, the more powerful and expensive it is.
Media Bay: The media bay contains the slots for playing and recording CDs and DVDs. Older laptops may only allow CD playback, while newer laptops allow you to play and burn CDs and/or DVDs. The more features in the media bay, the more you can do with your laptop, and the more you’ll spend.
Modem: Modems can take the form of dial-up telephone modems, or direct-connect satellite or fast cable modems. The faster your type of modem, the easier it will be to surf the web, and the more expensive your laptop will be.
Pricing will be affected by all of these specs, along with any additional features, how well-maintained the chassis is, the name of the manufacturer, and whether you buy the laptop from the factory or through a private dealer. Private dealerships charge less, but beware: not all dealerships are up to their restoration skills. Make sure you go to one that is reputable and experienced.
