How to Test a Laptop Battery
Batteries are one of the weak links in laptop computers. When you’re away from an outlet, your ability to use your computer is completely limited by the amount of battery power available. Batteries also tend to wear out faster than other laptop components, typically exhibiting performance degeneration with just two or three years of use. Once the performance gets bad enough, you’ll need to replace the battery. It’s fairly easy to test your battery’s charge and health, and by doing so you can help avoid unwanted surprises.
Is There a Difference in Ethernet Cords?
While there can be huge differences in the purpose and quality between one Ethernet cord and another, it's not usually what meets the eye. The color of the outside sheathing means almost nothing. Ethernet cables can be blue, yellow or even mauve. What's important is the order of the colored wires inside the cable, which is the difference between a patch cord and a cross-over cable. Another important difference is whether the cable is Category-5, Cat5e or Cat6. Finally, the cable's certification rating determines whether you can safely run the cable in an air duct, under a carpet or outdoors.
How to Troubleshoot a Linksys Wireless Router
You can usually tell when your Linksys Wi-Fi router stops performing properly by the decrease in wireless signal strength. There are several ways to deal with a weak or missing signal. Before beginning, if you get any signal at all from your router, try running a few speed tests over a period of several hours. Although not terribly accurate, speed tests can give you a general idea of ping speed -- the time your router takes to get to and from an Internet server -- and upload and download speeds for benchmark purposes. Check your wired connections for attachment and continuity before starting the troubleshooting procedure.
