Especially in the warm season it is inside the computer a lot warmer than in the cold season. This is because the components to be produced in the warm season a lot more heat. Many hard drives can be operated with a maximum of 60 degrees. At temperatures above 60 degrees, it becomes critical, because then threatened with a loss of data. With the help of special hard fans, hard drives can be kept refrigerated.

In setting up their wireless connection for the first time, Im discovering many individuals having problems connecting through Network Manager or other GUI wireless connection tools. In fact my Network Manager is intermittently buggy, connecting sometimes and not others. This guide benefits all users in case the GUI tools are not working, and is useful for testing a wireless connection during initial installation of wireless drivers since it provides for good debugging output.

Unencrypted/ WEP / WPA connections will be covered in this guide

Pre-requisites

1. Properly installed network driver — This guide can be used to troubleshoot driver installation to see if it is properly functioning

2. The ESSID of your router must be broadcasted and not hidden

3. Knowlege of your wireless cards driver (please see Prerequisite #4 to determine driver). Those using the r8187/r818x driver please see the end of the guide

4. Knowledge of your wireless card’s Interface Name – The user must know the proper interface of the wireless connection (wlan0, eth1, rausb1, etc). To discover this information, at command line type

lshw -C network

There may be multiple interfaces listed, however look under the section appropriate to your wireless device for the line labeled logical name. Here is an example

Troubleshooting a malfunctioning computer is a tricky task. A computer is made up of many components, and determining exactly which one is faulty is like searching for a needle in a haystack. Luckily, there are techniques that reduce the amount of hay you have to go through. This is the story of how I determined a faulty motherboard was the cause of my aunt’s computer problems.

When troubleshooting, two of the most important things to do is to maintain a logical attitude and to document. Without a logical attitude, you will become frustrated and overly repeat steps, thinking that if you try “just one more time” you will solve the problem. Logic dictates that if you have eliminated the impossible, whatever remains, however improbable, must be the truth. Therefore, trying the same thing more than a few times is useless. Without documentation, you will surely try a fruitless idea that you had already tried, and go around in circles. You will also be unable to reverse a mistake if you don’t know how you made that mistake in the first place. Thus, remember to document your results and maintain a logical attitude.

AC power adapter:

How the AC adapter works

The most common type of AC power adapter involves a small box, with one wire to go to the computer and another wire to go to the wall. There is usually an LED light on it, to tell you that it is on. (Is it lit on yours?) By the way, Apple notebook power adapters often have an LED that is actually built into the side of the computer, not into the adapter box, so obviously it won’t light up when it’s not connected to the computer.

This ATX power supply came in with the complaint of intermittent no power. When testing it with power on, I could see that the fan is not working. Not only that, some filter capacitors also became bulge because of the heat accumulated inside the power supply. The failure of the fan would not suck out the heat generated by the components especially the switch mode power transformer. If you switch off a working power supply and power removed, touch the power transformer, you could feel it is quite warm. Another heat source would be the heat sink where the output diodes attached to it. Diodes run a little bit hotter in filter circuit than diodes in other circuits due to the high current present at the secondary output line.
