No CD / DVD drive ? To solve the problem!

July 23rd, 2010

Netbooks have become increasingly popular : They are small and cheap, but one of its biggest drawbacks is the lack of optical drive. Most of the time it would hardly interfere , but we want a software from a CD or DVD , one has to rely on a few tricks. We reveal what they are.

231

Not only for netbook owners are the following tricks helpful. Even sub-notebooks usually have no CD / DVD drive and when the laptop or PC drive is adopted , if you want to burn an urgent Powerpoint presentation, or MP3s, will be more than the following tricks. Even if your drive is working perfectly , you save some of the tips even electricity of Dell inspiron 1525 battery- an important factor when working on the road.

Tip: A useful addition for Netbook users are also virtual CD drives around with them Virtual CD . Setting Once one of the following tricks used , the tool saves the Silberling compressed on the hard disk. You must apply the tip so a second time , but just start the virtual CD from the drive.

Effective Replacement: External CD / DVD drive

232

The simplest solution is an external drive that you connect via USB to the computer. Firewire models should be of interest because of the lack of connection on netbook or subnotebook for most users. His current pulls the external CD / DVD drive , depending on the model via the USB cable or a power cord from the Dell inspiron 6400 battery outlet.

If you value takes as little extra baggage , the ultra-thin slimline model. In addition, the user has the choice between external drives, move the CD on a tray , or through a narrow slit , similar to the CD player in your car. The latter option is usually even thinner , but does not mini – CDs. If you buy the drive you should use the most equal to a torch: With it, you not only read data , they also have backups on CD or DVD.

Usually lag the external CD drives their internal counterparts in terms of speed behind slightly. In our Comparison of the best DVD burner it creates an external burner but in the top 5. For an external burner you do not have very deep into their pockets , entry-level models cost substantially less than 40 €.

How to protect yourself from Internet threats hidden

July 19th, 2010

Anti-virus software and a firewall alone does not guarantee your safety. We show you how to thwart sneaky Internet attacks.

Do you know how to protect themselves against Scareware ? What about disguised as a text message from Trojans ? Or with data collectors in social networks? Malicious hackers develop targeted more new methods that exploit our way of dealing with computers and your apple a1175. New attack strategies and cautious deceive Internet users.

This effort is also to the data of the cautious and well informed to get PC users. On the following pages will be presented to the eleven most recent and most malicious Internet threats, and describes how you can protect yourself from them.

Shortened URLs

d77ab82f-16ec-4d58-be4e-f9f28cd4ab60

Many Tweets , and some other electronic messages contain links that will be reduced from services such as Bit.ly , Tr.im and Goo.gl . These reductions are often very practical, but also very risky. Because shortened URLs provide no indication of where you land after a click , attackers can use them to you so as to lure you to a malicious website by hackers .

Use a Twitter client

In the options of programs, such as web , you can specify that the secret behind the shortened URL is displayed as a page preview. When you click on a shortened URL in the tweets, opens a window that displays the page name and URL of full length. In addition, it says how many people have already hit this shortened link. With this information, you can now better evaluate whether you should click on the link to visit the hidden face behind it .

Install a URL preview plug -in

Some Web browser plug -ins and internet services also enable previews . For example, when creating a shorter web address with TinyURL You can select an option that allows other to see the site as a preview before you click on the link. On the other hand, you can offer a Preview Service , see if you want to visit a TinyURL link to earlier to see the full URL. This work TinyURLs preview options , your browser must accept cookies.

ExpandMyURL and LongURLPlease both offer Web browser plug -ins or Apps to verify the security of the full URL the acronym of almost all URL – shortening services. Instead of converting the shortened link to the full URL, checked ExpandMyURL the website in the background and colors the green link , if it is safe.also it is safe for your laptop and apple a1185.

Goo.gl , Google URL – shortening service ensures a degree of security by automatically the URL is scanned to detect any malicious websites. If the scan strikes , the user of this shortened URL will be warned that behind it lies a potentially unsafe site. Unfortunately, Google has restricted his service Goo.gl so that it is only in combination with other Google products and services available .

How good are cheap laptops ?

June 29th, 2010

However, notebooks are also equipped to sufficiently fast for the usual office tasks , for Internet surfing and DVD shows. Compute-intensive tasks such as image and video editing but need time and a lot of open programs slow down the computer tremendously – even a virus scanner can be a brake system . The Celeron M lacks also some power saving features of its big brother , so he behaves despite lower computing power in the Dell xps m1730 battery current eating well .

So you should invest a bit more money: From 650 € you will find even dual core notebook with a larger hard drive and 1 GB of RAM – in practice, the minimum Dell 1691P batteryfor a tolerable work with Windows Vista, which to this notebook mainly in the Home Premium Version is installed.

Speaking of price : The online hunt for the biggest bargains you must not forget of course the shipping costs – at the price comparisons on the Web , they are not normally taken in account. Just as , for example, at Dell, where you pay up to 78 € for the sending of a notebook.

Equipment issues

The most expensive component in the notebook is the display – for low-cost laptops is so often saved dell inspiron 1520 battery power . For the everyday work ranges from the quality of most panels , however. Notebooks with a particularly bright, strongly colored or TV -capable display but cost significantly more.

Problems makes a mediocre display especially if you use the notebook as a PC replacement for your daily work . For this you should better connect an external monitor. However, many cheap laptops only a VGA output , the signal quality at resolutions for 17 -inch and larger LCD is a little heady . In this case, it is worth investing in a notebook with a DVI port.

Display brightness control

June 23rd, 2010

A major power guzzler is the notebook display . Therefore, you should reduce the brightness from inspiron 1520 battery as possible , what can be done via the BIOS on most devices with special keys or not. Please consult the device manual. Some notebooks even come with a sensor so that adjusts the brightness of each to the environment.

Defragment

On a hard drive files with increasing occupancy of the space divided into small pieces and stored separately . The heads of the hard disk must therefore move more often and longer, which is reflected in slower access and increased power consumption of Dell vostro 1510 battery.

234

Conveniently, Microsoft Windows already provides a program that arranges all the files again and joins together . In XP, you can find it under Start / Programs / Accessories / System Tools / Disk Defragmenter. Click on a drive , and then click Verify. Windows XP then says that the disk needs to be defragmented . In Vista , type into the search box in the Start menu and click Disk Defragmenter on the result. It opens to the defragmentation tool. Defragment Now starts the process.

Windows declutter

With every program installed Windows is cumbersome . Delete a software remains back often unnecessary ballast. With a few clicks, you clearing out your Windows.

Grab the first thing the integrated Windows – broom ” – preferably immediately after PC startup , if no programs are loaded. Click Open the My Computer, with a right to your hard disk partitions ( eg C :) , go to Properties and then click Clean up. Tick all the available options , with one exception: “Compress Old Files “creates a lot of space , but may slow down the opening and closing of programs and data to save Dell vostro 1500 battery consumption .

Windows Vista needs more resources than the previous version of XP. This reduces the battery life. Unfortunately, XP will no longer offered by Microsoft. Who does not have an XP CD lying around you should consider this system as a serious alternative to Vista into consideration.

Reinstall Windows

Not always an easy enough decluttering to help Windows to return to the old forces. In such a case, it pays to install the operating system. This requires a little more time, then this is to ensure the notebook significantly faster and protect Dell inspiron 6400 battery .

To optimize your Notebook

220
The most laptop users always is doing the same: the portable PC was initially incredibly fast, and plays a role at the startup in the length , open up a program , it takes a small eternity . Even the apple a1175 battery is initially bristling with energy quickly.

Thus Notebook tuning is called for. But notebook tuning extends not only to the built-in components , not all aging is merely the hardware fault. Even a poorly maintained system slows the pace. Besides Windows optimizations , there are many other tricks to help you help your laptop back to power – and the initial performance may even surpass . In the first part of this article to a notebook -Tuning show you how to use simple software tips bring your laptop back on its feet . Sometimes , however, leads no way around it , replace obsolete hardware components such as battery(apple a1185 battery)_, memory ( RAM) or hard drive. Therefore you read in the second part of this article , well worth the investment, really , and how to replace the components of the easiest.

Let’s go with the software tuning

Even with Windows – board resources can be optimized performance, battery(like inspiron 1501 battery) life and system stability. In addition, you squeeze it with free tools even more performance from your device. On the following pages we show you how Notebook- tuning by software . make

Disable components

Integrated WLAN and Bluetooth radio chips need constant power, which has a negative impact on Dell gd761 battery life. For this reason, are on most notebooks switch or slider to support the radio on or off easily . This is handy because you can enable WLAN and Bluetooth if you really need it .

Other components such as a built-in modem or an infrared port eat electricity. These can also be disabled , but not quite so simple. In Windows XP, open the Start / Settings Control Panel and double- click System. If this point is not available, you first go to Classic View. Open the Hardware tab, Device Manager.

221

In Windows Vista click the Start button and type in the search box Device Manager. After a few seconds, you can click it. All components are now grouped clearly listed. Look in Device Manager now the desired component, click them with right and select Disable . In the same way can be activated devices again.

But be careful : Turn only components from your laptop,such as Dell latitude d820 battery, you know. Otherwise, it may be that the system will not function properly. Pro tip : Another way to disable components, the BIOS. This method is particularly suitable for onboard devices that sit on the motherboard. When you see the startup of the computer press F1 or Del to enter the BIOS. The exact key is displayed at startup of the PC. The BIOS should now be an item ” Integrated Peripherals Setup ” or ” Peripheral Setup ” be present in the components such as the sound chip disabled (English disable ) can be .

Solid state disks hard disks to move the body

282

As an alternative to conventional hard drives therefore move more recently flash memory in the attentional focus. Flash memory, for example, used in USB sticks, MP3 players, mobile phones and digital cameras,IBM batteryand so on . You have two crucial advantages over traditional ferro-magnetic storage: they are due to the low access times faster than conventional hard drives, since it eliminates the time consuming placement of the read-write head. Also reduces the operating noise, as there are no moving parts. And for the same reason, flash memory are much more secure than magnetic storage, as the dreaded head crash, so the placement of the read-write heads on the platters, here are impossible. And average access time in the “zero point field” are also more than impressive.

Moreover, need flash memory for read and write far less power from Dell inspiron 1501 battery than traditional hard drives. Flash memory drives – so-called Solid State Disks (SSD) – will need about 0.5 watts under load, while classical disks the power failure about four times higher (see above). At rest in flash memory hard drives even simply sensational 0.1 watts can be achieved. These values are achieved mainly because in these media are no moving parts such as electric motors are used. During the operation also creates much less waste heat stromzehrende.

Flash memory directly on the motherboard

In practice, flash memory but are not only used as a USB flash drive or hard disk replacement. As an example, at this point Intel’s specially developed for the Merom processor and the Crestline chipset, “Robson” technology mentioned. Here is a flash memory integrated directly onto the motherboard and uses it in addition to memory for faster access to data and on Save electricity of Dell inspiron 6400 battery , because the disk is not activated. but we follow the views of market researchers, will be equipped in the near future the majority of all notebooks with flash memory drives – then no longer necessary Robson.

Thanks to energy efficient components, the entire system produces less waste heat, which must be dissipated. Must work, for example, the fan less often or can perform their work with a lower speed – and that ultimately saves power and reduces the way, the operating noise of the notebook.

Displays: reduce the power consumption of LEDs Better

While in 2003 the average power consumption of notebook displays still was 4.5 watts,like apple a1185 battery , have modern notebook displays now an average power consumption under 3 watts. The reduction appears to be low, but on average it may indicate up to 60 minutes longer battery life.

Samsung plans for the second half of the introduction of LC displays in which the backlight is provided by white LEDs. This is the power consumption of 2 watts are reduced and also a sensational contrast ratio of 10,000:1 be achieved. In the future, the manufacturer wants to go even further and introduce an AMOLED display (Active Matrix Organic Light Emitting Diode). A screen with this technology is extremely thin, very bright lights and consumes less power of Dell gd761 battery. In addition to AMOLED displays have an extremely high contrast of 1,000,000:1.

Graphics solution: Big savings

May 27th, 2010

For the power consumption of a notebook is the graphics technology used is of particular importance. The most basic way to reduce power consumption consists in choosing the right graphics card. Thus in the chipset integrated graphics solutions compared to dedicated graphics cards a much lower energy consumption. Since they are practically in classical 2D applications such as Office applications, the same performance as “providing real” video cards, they are for most users a completely satisfactory choice. Dedicated graphics cards from Nvidia or ATI offer, especially in multimedia applications demanding more power of Dell latitude d830 battery , but are especially important for playing modern 3D games.

On-board graphics vs. dedicated graphics

Graphics chipset to work with shared memory technology and bring no or very little suitable with video memory. Instead, they show a more or less large part of the memory of the notebook. The advantage here is that decreases due to the elimination of additional memory chips, the power consumption.

The difference is obvious: With an average laptop with a dedicated graphics card power consumption from Dell inspiron 1525 battery is around 22-25 watts. For a comparable device with built-in chipset graphics solution it is in the cut at 14-16 watts. A disadvantage of this method, however, for the use of RAM for the graphics leads to a slight slowing of the overall system and limited course, the normal applications for the available memory.

Energy management for the graphics card

The manufacturers of modern graphics solutions also put more emphasis on energy-efficient solutions that can be fine-tuning via software. Nvidia Sun, with its power mixer technology an intelligent power management, which aims to effectively conserve power and extend battery life. This technology continuously monitors the power consumption in different areas of the graphics processor. Depending on the workload of the individual components, the power is adjusted automatically. This process is so fast that the user perceives no power fluctuations. The result is an optimized power consumption, which is indicated by a longer battery life.

The following features are particularly interesting for low power consumption for Dell inspiron 1501 battery : The adjustment of the timing and engine ensures that the graphics processor uses only the really needed energy. The powerful high-definition video processor ensures the highest image quality, reduces CPU usage and extends battery life. For greater efficiency provide more circuits and tracks with a lower voltage. And Nvidia SmartDimmer technology ensures, for example, an intelligent and accurate brightness setting at maximum battery life.

Disks: differences in speed and standby

272

Regarding the laptop hard drives, the trend is similar to the models for desktop PCs, to more and more storage capacity. Since laptops but always the energy consumption from Dell inspiron 5100 battery , especially in the foreground, new hard drive models have to offer in this area interesting news. For example, work the gigantic 500 GB hard drives-making Fujitsu MHZ2 BT (4200 rpm) and Hitachi 5K500 (min 5400 rpm) according to manufacturer’s instructions with a power consumption during read and write accesses with only 1.8 respectively 1.9 watts.

Significantly, however, the difference in phases without access activity. Here the slowly rotating Fujitsu hard drive scores with a consumption of only 0.5 watts, while the Hitachi model resembling a 0.95 watt is almost twice as high energy consumption of Dell Latitude X200 Battery . What development has taken place in recent years, shows the following example: The 60-gigabyte hard drive from Fujitsu MHT2060AH from 2004 still consumed 2.3 watts for read and write operations, and 0.85 watts in sleep mode. Given an approximate tenfold increase in capacity and increase the transfers represent a very important step in the right direction.

PC-strike G

May 21st, 2010

Bent Pin

Fast it happened: On VGA cables to the motherboard or even the processor is one of the delicate, thin connector pins bent. straighten this again is hard. If you lack the necessary sensitivity, you may aggravate the situation and breaks the pin completely off. not a new VGA cable will cost the world, a new processor, however, tears a hole in the purse. Although we can not guarantee success, we give a tip on how to get the pin back straight. Instead of a pair of pliers as a tool, take a pencil, remove the mine you. The metal tip often has the diameter that you need for the bent pin. Slide the tip very carefully over the pin and align it so gently again.

Discontinuous presentation

They contribute eloquently before your PowerPoint presentation – and then it happened: Your laptop is on the mind. Maybe the power supply is to blame. Take out the battery and try to start the device. Defective batteries sometimes make problems.

Better safe than sorry: Place a small reserve package in the form of a USB stick ready. This contains a copy of your entire presentation and the portable version of the free office suite OpenOffice.org. Installation is simple: After downloading the Open Office Portable double click the EXE file, specify as the destination for the file to the drive letter of your USB stick and click on Extract. The USB stick, you can now connect to any Windows PC, start on the USB stick, the Impress program from Open Office and open the presentation with it. Test before the real thing, whether the most important elements of your presentation in this manner to display properly.

Be careful with hardware

It pays to treat all hardware with the utmost caution. If refuse external devices connected to their work, be sure to check that they are any lights or flashing signals from him. The manual decipher such codes usually in a chapter on troubleshooting. It is often not the device itself, which occurs in the strike. The connections Cable and plug in the strike also stupidest moment. Test is whether e.g. a reluctant USB flash drive to another USB port running. Use of a recalcitrant printer a different cable. Expect to pay at all about your PC anyway always the worst. Prepare yourself organized with smart backup to the emergency. Keep installation CDs and license keys from the operating system, hardware drivers and software in a quickly accessible place.
