How to identify prevent and fix laptop overheating

26th March 2012 5 Replies UCS2012

For the last few years, the sale of laptops has increased by 25% whereas the sale of desktop machines has reduced. Along with increasing demand for laptops and a change in times, technology has been upgraded.

Day by day laptops are getting thinner, more compact, lighter, and better in terms of performance. Because of this, laptops are now being put into smaller and smaller casing, which increases the threat of overheating, as there is less room for air to circulate.

If your laptop overheats, it can cause permanent hardware damage or failure. In this article, I will try to teach you about how to identify, prevent and fix laptop overheating.

Symptoms of Laptop Overheating

Below are the three points which can help out to identify if your laptop is overheating.

Sudden shut-down, done by the operating system to prevent hardware damage
The fan speed increases – you should be able to here this
A reduction in the laptops performance – things load slower, the CPU is busy more often etc.

The Root Cause of Laptop Overheating

Laptop overheating occurs due to insufficient cooling. This usually happens because either your laptop is clogged up with dust, blocking ventilation, or because a thermal grease compound is getting stocked between your CPU and the heat sink – the big metal cooler that is usually linked to the fan.

Steps to prevent or fix Laptop Overheating

Option 1 – External cooler

You could purchase an external cooler. This is a cooling pad you place your laptop on, and it keeps cool air circulating around the laptop. Before you but a cooling pad, it is important to understand the flow of air in and out of your laptop.

Cooling pads are more useful/effective when used on laptops with air vents on the base of the device. Cooling pad connect via USB, and consumes some of the laptops power – not a problem if you are plugged in. Usually these pads cost around £5-20 GBP.

Option 2 – Get a strong and level base

Most laptops have their ventilation grills on the bottom of the device. Therefore if you keep them on an uneven surface, such as a bed, lap or pillow, disturbance is caused to the airflow. Keeping your laptop on a hard surface, like a table or a strong hard tray is likely to get you good air flow..

Option 3 – Internal cleaning

The above two methods were external methods, however this method will require taking your laptop apart and putting it back together again – so only do it if you are confident you know what you are doing!

This step is about removing your laptops casing to clean out any dust or dirt that might be restricting the airflow. Most laptops have downloadable user manuals, which can tell you all about the internals of your laptop, and how to take it apart, in order to clean it. This can void your warranty, so be careful and do your research! If you are not confident, you could of course take it to your local computer repair shop, and ask them to clean it.

If you are doing it yourself, once you have opened your laptop, you will need to clean the fans which provide cooling to graphics card and CPU. Before you do this, make sure that it is shut down and the battery is removed – don’t electrocute yourself! For thermal grease you may need to use a cotton swab, dipped in stain remover to remover.

For full, comprehensive instructions, research it yourself, and do not start opening your laptop up until you know what you are doing!

SD10 Bluetooth Stereo Headset – Review

19th March 2012 21 Replies Christopher Roberts

Previously I have reviewed the Pocket Boom, a cool little device which can turn virtually any device into a speaker. Recently the same people asked if I wanted to review a SoundWear SD10 Bluetooth Stereo Headset, so here I go!

Please note, like with the Pocket Boom Review, all the opinions in this article are mine, and are completely honest – I am not being paid to write this review.

The SoundWear SD10 Bluetooth Stereo Headset is a device which provides wireless headphones, which can synchronise with almost any Bluetooth device. This means that when you are out and about, you can take calls, and listen to music, without the limits of wires.

Ergonomics

The headset very cleverly folds away quite neatly, which does mean that they can fit into your pocket without much of a problem, meaning they are portable, like you need them to be.

The headphones when they are folded up would fit in your pocket

So, are the headphones comfortable to wear? My answer would be it depends who you are. I have tried them on, and I have got other members of the team and some of my friends to try them on, and the responses you get are mixed. Some people have no trouble whatsoever, the headset fits snugly onto their head, and are very comfortable to ware. Other people have tried them on, and they do fit, they are just a bit more awkward. Maybe that’s something you might want to consider – especially as they are not retractable/adjustable.

Ease of Use

Like with the Pocket Boom, if you don’t read the instructions, you aren’t going anywhere very fast! Read what the small A5 (ish) sheet of paper tells you, and things become pretty simple.

With some phones you need to fiddle with some settings either with Bluetooth, or on audio tracks to get them to work properly with calls and music, but it does work!

Sound Quality

Obviously one of the most important things with all headphones is the sound quality. You can get the most amazing headset, but if it has poor sound quality, then there is little point to it.

So what about the quality of the audio stream produced by the SD10 Bluetooth headset? Well it is actually very good! The headphones fit very snugly around your ears, reducing any noise interference, and the audio quality is very respectable.

Obviously noise cancelling headphones, or recording studio ones would be better, but the quality is very respectable, especially as it is coming from a wireless stream. For the average music listener, I don’t think there is any need to worry about poor sound quality.

Instructions

The headphones do come with instructions, which are clear, and just require a small amount of common sense and logic to use. They are helpful, but could contain a little more info – possibly room for an FAQ’s section.

Power

From what I have seen of the headset, it seems to last a reasonable amount of time between charges. You don’t start listening to a tune, and then a call comes in, by which time the headset has given up and is needing a charge. The battery life seems to be pretty good, so no need to worry about that.

The issue I have with power is the way you charge the headset – via USB. You can only charge it via USB, and there is no alternative, no batteries you can replace etc. This can be a little inconvenient, especially as it doesn’t come with a USB plug adaptor, but I am sure it will work okay with the one I use for my iPod, or the one I use for my camera. Don’t take my word for that, I wouldn’t want to blow your headset – if you have one or are getting one!

Value for Money?

Here comes the killer question: is the SoundWear SD10 Bluetooth Stereo Headset value for money? I try to evaluate every product I review using value for money, so it is a good test. The headset retails at £24.99, which is reasonable, but I think it depends what you need it for. If you are going to be making calls wireless and listening to music, go for it. If you just want to listen to music (like me) then I am not so sure. There are different headphones more suited to music listeners, but this set does give you the added bonus of being able to make calls.

As I said at the beginning of the article, this product has been sent to Technology Bloggers to review. Our thanks to Mobile Fun who provided us with the headset.

Steps to Take Before Throwing Away Your Old PC

29th February 2012 13 Replies Daniela

In 2010, the FTC recorded over 250,000 complaints of identity theft in the United States. While many identity thieves still get their information from your paper mail, a stolen purse or wallet, or hacked files online, more and more are starting to glean sensitive information from the hard drives of old computers. If you’re getting ready to toss out your desktop or laptop in favor of a newer model, take these steps to protect yourself from identity theft.

What information might be stored?

Not sure it’s worth all that work to wipe your hard drive? After all, you don’t keep a ton of important information on your computer, so what could a hacker possibly find anyway; and if you’re just donating your computer or selling it for cheap, what are the odds that an identity thief is going to get his hands on it?

The problem with this line of thinking is that often times, your computer has stored information that you don’t even know it has stored.

Common information stored on computers includes account numbers, credit card numbers, passwords, registration keys for software programs that you use, medical information, addresses, and even tax returns – which contain pretty much all the personal information necessary for a someone to apply for a credit card or bank loan in your name!

Keep in mind that many identity thieves will actually buy a used computer – or even steal a donated one – in the hope of gleaning such personal information. This information can be worth thousands of dollars to them and can create a huge headache – and financial problems – for you.

How to get rid of the data

So, before you sell your computer or donate it to your local school system, take these steps to get rid of the data for good:

1. Don’t count of just deleting the files. While you’ll want to delete the files from your computer, this is just the first step to take. Identity thieves are often experts at getting deleted information from hard drives by using specialized software.

2. Save any files you want to keep. Before you wipe your hard drive, you will, of course, want to save any files you want to keep. You can transfer your data to a new computer, burn it to a CD, put it on a USB drive, or put it on an external hard drive – a particularly good option if you need to store a ton of files or information.

3. Use a utility program specifically meant to wipe your hard drive. Local tech stores will sell utility programs meant for this purpose that match up with your specific operating system. The best idea is to get a program that will overwrite or wipe the hard drive several times instead of just once, and you’ll definitely want a program that wipes the entire drive.

If you know your computer has particularly sensitive information on it and you don’t trust a utility program to get rid of the information, you can always destroy the hard drive physically.

Businesses in particular, often use hard drive shredding services, as their computers tend to have lots of personal information on both employees and customers of the business.

A hard drive being shredded

Once you shred the hard drive, you can simply sell or donate the rest of the computer without it, and the new owner can then completely replace the hard drive.

Watching for identity theft

Even if you are careful to destroy information on your computer before you sell or donate it, it’s a good idea to be wary of potential identity theft.

Check your credit reports regularly to ensure that everything is accurate. Credit reports are normally the first place you’ll see evidence of identity theft when new accounts pop up that you didn’t open. If you do think you’ve been a victim of identity theft, get identity theft assistance as soon as possible.

Report the problem to the credit reporting bureaus, who will place a fraud alert on your account. Then close the new, fraudulent accounts. Finally, report the fraud to the Federal Trade Commission and your local police department.

If you’ve taken steps to protect your personal information from being stolen, you may never have to deal with the problem of identity theft, but it’s always a good idea to be aware of what you should do if your identity should be stolen.
