Finding the Best Laptop Computer

If you are in the market, then youll want to find the best laptop computer for you. Note that last phrase "for you" because it is a critical part of the purchase process. Too often people interpret "best" in the wrong way - most expensive, slickest, fastest, or state-of-the-art bleeding edge technology. The best notebook computers are tools that meet your own needs without unneeded features or expenses. So begin at the beginning.

First, you need to consider your budget. The best laptop computer for a college student is unlikely to be in the same price range as a machine that a graphics designer needs. Most people probably overestimate their needs and end up either paying too much or paying for the wrong features. Before you start narrowing things down, settle on your budget. A college student probably doesnt need to spend a small fortune on top of their other expenses. You should also be sure you truly need a laptop and, if so, whether it will be your only machine. If most of your work will be done on a desk top machine and you only need a laptop when traveling, you should be able to keep your costs down. But, if its going to be the machine you do everything on, you will likely have to spend more.

The only real advantage to a notebook computer is that they are portable. They are more expensive than desktop systems to begin with and they are also harder (and more expensive) to repair or upgrade. For a college student they can be essential if you need to carry one to class and take it with you on vacations or trips home. If you work in multiple locations without desktop systems in each, you also need a laptop. If you travel and need a computer on your trips, you sure dont want to lug a desktop with you. Weight can be an issue to consider if you plan to do a lot of carrying. But there can be a trade-off - lightweight often means a smaller screen and keyboard and shorter battery life.

In terms of budget you do have some choices you may not have thought of that can reduce your cost or get you more machine than you expected. Discontinued models, older models, and factory reconditioned notebook computers are often available at substantial discounts. Last years best notebook computers are often this years best deal. If you do look at reconditioned machines make sure they were reconditioned by the manufacturer and come with the same warranty a new machine has. Ive used the same factory reconditioned notebook daily for close to 5 years - it was an incredibly good deal so keep the possibility in mind.

Now you need to analyze what you are going to use your laptop for: will you be doing a lot of intensive data applications or graphics applications; do you need it to play high end games; will you be using in places or in ways that may require a ruggedized system; will you just be primarily writing documents, using the internet and doing email; do you need wireless connectivity; what external devices might you connect and what kind of connectors do they need; do you need to be able to write DVDs/CDs or just read them. You may also want to consider whether how the laptop looks is important. That may seem superficial, but under certain circumstances such as high level business meetings, style could be an important feature of your best laptop computer.

The more complex and intense the applications are that you will be using, the faster a CPU and the more RAM and hard disk space you may need. Operating systems and programs are using more and more CPU, memory and disk space all the time so this is not a trivial issue. These days Id suggest that a minimum configuration should include at least a 1.5 GHz CPU, 1 Gigabyte of RAM and a 60 Gigabyte disk drive. A DVD/CD reader is a minimum and most people will probably want the ability to also write DVDs and CDs.

Before you actually start looking, use paper and a pen, go over your needs and requirements and write them down. Essentially you want to create a checklist to compare to the features of models that interest you. Once you get started, keep your budget firmly in mind. Often youll find the best price for your personal best laptop computer online. If you can, before you actually buy, find the same model in an offline store and check the screen size, the keyboard and how the weight feels to you. Weight may be less important but you may also be carrying other accessories. The screen and keyboard are critical components for comfortably using your computer. Dont settle for a screen thats too small or a keyboard that feels cheap or clumsy. Take the time and put in the effort to make sure you end up with the model that suits you best.

The different types of dell laptops are


1. Ultraportables:Laptops have screens typically less than 12 inches diagonally and weigh less than 1.7kg. Their primary audience is usually business travelers who need small, lightweight laptops. Ultraportables are often very expensive and house power-saving CPUs and almost always have integrated graphics.

2. Thin-and-lights:These are the Laptops which weigh between 1.8kg and 2.8kg with a screen size of 12 or 14 inches diagonally.

3. Medium-sized laptops:These are usually having screens of 15 - 15.4 inches diagonally and weigh around 3-3.5kg.

4. Desktop replacement computers:These are powerful laptops mainly used in a fixed location and infrequently carried out due to there weight and size. They provide more space for powerful components and a big screen - usually measuring 15 inches or more for desktop replacements and often have limited battery life due to their hardware, rarely exceeding three hours.

Dell manufactures its products close to the customers. The assembling of desktop computers for the North American market takes place at Dell Laptops plants in Austin, Texas and in Winston-Salem, North Carolina with servers built in Nashville, Tennessee. Dell, Inc. assembles computers for Europe in Limerick City, Ireland. The major competitors of Dell are Apple, Hewlett-Packard/Compaq, Packard Bell, Sun Microsystems, Gateway/Emachines, Lenovo, Sony, Toshiba, and MDG Computers in Canada. Enthusiast market competition takes place with Alienware, now which is a Dell’s division- Falcon Northwest, Voodoo PC, WidowPC, Sin Systems Inc. and other manufacturers. By August 2003, Dell Laptops lowered their product prices by 22% in an attempt to generate more sales; however this disappointed shareholders, sending it shares down by 2% in late Wall-Street trading, amid fears of a sector-wide slump.

Laptop is dead How to troubleshoot the problem

Laptop is dead. How to troubleshoot the problem.:
In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.
Let’s take a look at two different scenarios.
Example 1. The laptop is absolutely dead.

When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.
What you can do in this case?

1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.

2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.

3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.
OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule:

The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.
If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack. Check out this guide for fixing laptop power jack.
Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start.
Troubleshoot dead laptop




First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint. If that’s the case, check out these tips for troubleshooting laptop with backlight failure.
Connect external monitor
If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations.
Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable.
Test external video
In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory.
Replace reseat memory module
Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead.

If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots.
In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on.
Remove hard drive DVD drive
Try removing battery, hard drive and DVD drive and turning on the laptop without these components.
Disconnect display
Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel.
Remove laptop components
In my case removing the hard drive and DVD drive didn’t help. Unplugging the video cable didn’t help either.

I continued taking my laptop apart piece by piece and tested it after each step.

I removed wireless card, modem, disconnected the keyboard but it didn’t help.
Test laptop with external monitor
I still wasn’t able to boot the laptop with video on the external monitor.
Disassemble laptop
Finally, I disassembled the laptop and removed the motherboard.
Test laptop motherboard
On this picture you see my final test. The motherboard has been removed from the base and I assembled basic barebone system on my bench.

1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard

2. CPU with heatsink and cooling fan.

3. Known good memory module.

4. The power button board witch I need to turn on the system.

5. Working DC power adapter.
Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video.
At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard.

The new iPad runs the iPhone OS and thats the problem

By Jay Garmon

No matter how excited you are about the 9.7-inch HD display, capacitive multitouch interface, or staggeringly cheap 3G data plans promised by Apples iPad, theres one feature thats billed as a benefit but may prove to be more of a bug: The iPad runs the iPhone OS. On the surface this seems like shrewd platform cross-compatibility, but do you really want to pay between $499 and $829 (plus data plan) for a device that actually does less -- as in no built-in camera, no phone -- than your iPhone?

While you may be smiling inwardly at the notion of getting all your existing iPhone apps ported to your iPad for free (youve already paid for them), theres a question of whether anyone really wants to run apps designed for a phone-sized screen on a tablet-sized display. During Steve Jobss demo today, we saw this phenomenon in action. Either the iPhone app ran at native resolution as a floating block inside a lot of blank screen real estate, or the iPad upscaled the app to its full screen resolution, presenting you with ridiculously oversized icons and buttons. Wef one could run multiple iPhone apps side by side on the iPad, that would be worth talking about, but that brings me to the second problem with building an iPhone OS-based tablet: No multithreading.

The iPhone OS cant run background processes. Wet cant have two apps open at the same time. You cant chat while watching a video. You cant read the New York Times while listening to Pandora. You cant toggle between a word processor and a spreadsheet, or a Web browser and a presentation. Thus, while you can get an iPad version of iWork for $30 ($9.99 each for Pages, Numbers and Keynote), you wont be using any of those apps simultaneously -- which is how many of us work best. Heres betting that most iPad adopters will want to rebuy most of their apps in iPad versions, which makes me wonder why the iPad couldnt get its own multithreaded OS to begin with.

The other major drawback to the iPads iPhone OS-basis is a lack of support for Adobe Flash. Well accept not being able to render highly interactive Flash Web sites on my phone, but on a high-end media consumption device like the iPad We should be able to open every Web site on the planet. This Flash incompatibility also bans any Web video player that isnt Quicktime or Youtube. Sorry budding filmmakers, but there will be no Vimeo or Hulu or Yahoo Video for you on the iPad. Jobs himself showed a failed Flashplayer icon during his Web surfing demo today, so clearly Steve isnt perturbed by this feature limitation, which wont be solved until HTML5 reaches full adoption -- months or years from now.

On the bright side, the iPad running the iPhone OS does mean that the new iBook store will be cross-compatible with the iPhone, which is great news for iPhone owners. The iBook store will sell ePub versions of books from major publishers, which means digital reading just got a boost, if only because iBooks will appear on the worlds most popular mobile phone. That said, We dont expect the iBookstore to truly revolutionize publishing, both because the $14.99 price point suggested for iBook titles is still too high, and because We cant rip my existing dead-tree books to the platform. While almost anyone can copy a CD into iTunes easily, almost no one can scan in paperbacks to iBooks with any speed or grace. At $14.99 each Wem not going to rebuy all my favorite books for the iPad.

Now that the iPad SDK is in the wild, We expect developers to create new and innovative applications and content that truly take advantage of the iPad form factor, display, and interface. Until those iPad-native apps show up, however, Well reserve judgment as to whether the iPad is the successor to the glorious iPhone, or the ignominious Newton.
