Use a USB wireless adapter with your laptop 

by on April 27, 2010

Q: Is it possible to use a USB wireless adapter with my laptop that already has wireless built in?

A: Yes you can use a USB wireless adapter with a laptop that has wireless already built in. Some of the reasons you might do this would be that your internal wireless isn’t working anymore or maybe you need to connect to two networks at the same time. The setup is fairly easy on most computers but I do suggest reading the instructions. Sometimes you have to install a driver first and other times you can just connect the USB wireless adapter and it will just work.

logon.scr 

by on April 26, 2010

Q: What is logon.scr?

A: Logon.scr is the Logon Screen Saver that is shown before a user logs in. It can be disabled but to disable it requires you to modify your registry so we suggest you don’t do it. This means it is not a critical component of your Windows operating system but it doesn’t hurt anything when it runs so we suggest leaving it.

The Blackberry 8830 cannot act as a WiFi hot spot 

by on April 25, 2010

Q: Is there anyway to connect my Blackberry 8830 to my IPod Touch and access the Internet?

A: Some phones have the ability to act as a WiFi hot spot. One example would be the Palm Pre on the Verizon network (I don’t believe it can on the Sprint network though). Unfortunately the Blackberry 8830 is not one of those phones. Down the road I hope we see a lot more phones that have this ability because as we get more and more devices it doesn’t seem right to have to keep paying for an Internet connection with each device.

by on April 23, 2010

The nice thing is anything released by Microsoft usually has a KB (knowledge base) number and that can be used to find out more information about the specific item. Read the rest of this entry »

Correctly storing rechargable batteries for long periods of time 

by on April 21, 2010

Q: What is the best way to store a rechargeable battery for a long period of time?

A: This is a little tricky because all manufacturers have slightly different recommendations for what to do before you store a battery for a long period of time. Most NiMH and NiCD manufacturers suggest you fully charge your battery and then recharge every 3 to 9 months. I personally suggest you fully charge the battery and get on a 6 month schedule. L-ion batteries are a bit more complicated but it seems like most suggest you fully discharge the battery and store it in a cool place. I highly suggest you check with the manufacturer when it comes to L-ion batteries though. Read the rest of this entry »

Protect your portable electronics 

by on April 20, 2010

Q: I have a suspicion that my laptop was stolen and switched with a broken model. Is there anyway for me to know if my laptop was switched?

A: The only true way to know if any electronic device is yours is by knowing the serial number. Every portable electronic has a unique serial number on it and you should make note of the serial number in case it is ever stolen. You can also put unique markings on the device as well, like your initials in a specific spot. I highly suggest you always take pictures of the initials and where you put them on the device in case it ever goes missing. Read the rest of this entry »

Unlock the quad core in your CPU at your own risk 

by on April 18, 2010

Q: Is it safe to unlock the Quad core in an AMD Phenom II X2 550 Callisto 3.1GHz processor?

A: You need to know that attempting to unlock these cores will void the warranty on the CPU if you bought the CPU alone. If your CPU is part of a complete system that you bought then it could void the warranty on the entire system. The next important thing to know is that every CPU is different. This means that you could unlock it and never have any problems or you could unlock it and kill the CPU. So unlocking the quad core on your CPU could go very well or could go very bad and there is no way to guarantee which way it will go.
