+<title>Why is the laptop fan always running?</title>
+
+<p>If your laptop's cooling fan is always running, it could be that the hardware that controls the laptop's cooling system isn't very well supported in Linux. Some laptops need extra software to control their cooling fans efficiently, but this software may not be installed (or available for Linux at all) and so the fans just run at full speed all of the time.</p>
+
+<p>If this is the case, you may be able to change some settings or install extra software that allows full control of the fan. For example, <link href="http://vaio-utils.org/fan/";>vaiofand</link> can be installed to control the fans of some Sony VAIO laptops. Installing this software is quite a technical process which is highly dependent on the make and model of your laptop, so you may wish to seek specific advice on how to do it for your computer.</p>
+
+<p>It is also possible that your laptop just produces a lot of heat. This does not necessarily mean that it is overheating; it might just need the fan to run at full speed all of the time to allow it to stay cool enough. If this is the case, you have little option but to let the fan run at full speed all of the time. You can sometimes buy additional cooling accessories for your laptop which may help.</p>

    <p>Explain why the fan might always be running. It could be because the processor is always running at its full clock speed, or that the Linux drivers for the motherboard don't handle the fan very well.</p>

+<title>My computer gets really hot</title>
+
+<p>Most computers get warm after a while, and some can get quite hot. This is normal, simply part of the way that the computer cools itself. However, if you computer gets very warm it could be a sign that it is overheating, which can potentially cause damage.</p>
+
+<p>Most laptops get reasonably warm once you have been using them for a while. It's generally nothing to worry about - computers produce a lot of heat and laptops are very compact, so they need to remove their heat rapidly and their outer casing warms up as a result. Some laptops do get too hot, however, and may be uncomfortable to use. This is normally the result of a poorly-designed cooling system. You can sometimes get additional cooling accessories which fit to the bottom of the laptop and provide more efficient cooling.</p>
+
+<p>If you have a desktop computer which feels hot to the touch, it may have insufficient cooling. If this concerns you, you can buy extra cooling fans or check that the cooling fans and vents are free from dust and other blockages. You might want to consider putting the computer in a better-ventilated area too - if kept in confined spaces (e.g. in a cupboard), the computer's cooling system may not be able to remove heat and circulate cool air fast enough.</p>
+
+<p>Some people are concerned about the health risks of using hot laptops. There are suggestions that prolonged use of a hot laptop on your lap might possibly reduce (male) fertility, and there are reports of minor burns being suffered too (in extreme cases). If you are concerned about these potential problems, you may wish to consult a medical practitioner for advice. Of course, you can simply choose not to rest the laptop on your lap too.</p>
+
+<p>Most modern computers will shut themselves down if they get too hot, in order to prevent damage from occurring. If your computer keeps shutting down, this might be the reason. If your computer is overheating, you will probably need to get it repaired.</p>

    <p>Explain that this is usually OK, but sometimes you might need to check that it's not overheating. List ways to keep the computer cool. Mention how to check the CPU/system temperature (probably have to use the terminal).</p>

 <title>I have no wireless network when I wake up my computer</title>

+<p>If you have sent your computer to sleep (suspended it) or hibernated it, you may find that your wireless internet connection doesn't work when you wake it up again. This happens when the wireless device's <link xref="hardware-driver">drivers</link> don't fully support certain power saving features. Typically, the wireless connection fails to turn on properly when the computer wakes up.</p>
+
+<p>If this happens, try turning your wireless connection off and then on again. If you have a power switch for the wireless card, turn it off and then on again and see if it works. Some laptops have a keyboard shortcut that can be used to turn the wireless on and off; its icon often looks like a "radio beacon". You can also try clicking the network icon on the top bar and unchecking <gui>Enable wireless</gui>, waiting for a few seconds, and the re-checking it.</p>
+
+<p>If this doesn't work, restarting your computer should get the wireless working again.</p>
