Cross over or straight cable?

Commonly used cable is the RJ45 cable. It is divided into 2 names: straight and cross-over cable. A straight cable is used for connecting 2 different devices. PC to Hub is an example of it. It is used by an RJ 45 but it is in “straight” configuration. Just think of the cable as the passage of data or information from location A (PC) to location B (HUB) or vice versa. It is called straight coz physically; we don’t need to cross the cables so we can connect the 2 devices. On the hub’s side, the internal circuitry will do the math for you. I term this as GBB. On the other hand, the cross-over cable is used for connecting the same devices (like hub to hub). There are 4 twisted pairs on a RJ45 cable. Pair1 is blue, pair 2 is orange, pair 3 is green and pair4 is brown. All pairs have white cables twisted with the main colour cable as shown below. Take note that from Pins1-8, all odd numbers are for white colours. For the meantime, I want to use the term GBB for the straight cable, and OBB (orange blue brown) for the cross over cable. So if networking should be done: a combination of more than 2 computers plus switches and hubs, you can use these 2 cables. What are you going to use? straight is different, same is cross. If you're not sure, try each cables and see what will work.

your computer hero is ranked 1

I never thought having rank 1 for this site is impossible to achieve, since I think there are no visitors. To my surprise when I checked google page rank checker that it ranked 1 out of 10 in a span of only 6 months. I started creating this blog late last year (December 2008), and it gained recognition today! What a wonderful accomplishment for this blog! Thanks to the readers to which I don’t know where you’re coming from. All I wanted to do for this blog is to record my troubleshooting steps I did on a certain given time and computer, as my reference for future similar problems. Not wanting to make such a rank. But anyway, since it is here, I’m here to expand the capabilities of this blog. Paalam!

Toshiba Satellite Disassembly

I had a rough time disassembling Toshiba Satellite A200 with the link I created with this post. When I checked this site, I'd say, this is incomplete! And decided to create a post so I have a reference in the future (but that will come later since I have to deal with the Toshiba). The problem of the laptop I'm working with is it's VGA port is not working. When an external monitor is connected to it, you cannot see anything on the other monitor. Even if you set the correct settings. So I decided to open it and perhaps reseat the cables. And so I did. I had a rough time since when I'm checking the net, there are no how to's for removing the keyboard, then the keyboard bezel and everything inside. Accidentally I removed the bezel, and everything falls into proper place. This is chicken and so I thought. I reseat the cables of the VGA port, and it is not part of the mobo so if this is broken, we can replace. To my dismay when the computer is running again, the VGA is still not working. When I finally checked the site, there are pages 2-4 to look at, adding to my dismay. I was figuring out what to do next when I haven't seen those pages when in fact they are there to give support. To you man who posted the troubleshooting steps, thank you so much.
