Install Laptop RAM

Install Laptop RAMAbout a month ago, I just learned how to install Laptop RAM by myself.

It was for my wife's old laptop which we bought in 2006. Her laptop had only 248Mb of RAM (Random Access Memory). RAM is important for multimedia applications, games, and for doing several things simultaneously in your computer.

We were feeling the old age of her laptop whenever she goes to her Facebook page, or whenever she opens iTunes to synchronize her iPod. Based on the manufacturer's analysis of our laptop's specs, it was determined that its performance would significantly improve once we install laptop RAM.

Looking for a laptop RAM upgrade is not that difficult. We had to make sure the RAM specs are compatible with our current system. In our case, our laptop had 2 memory slots that could be used to 1Gb RAM each. The RAM upgrade also had to be the correct frequency with the mother board to work properly.

Another learning was that it's harder to find the older memory specs because they were already obsolete. It was also sometimes more expensive because of the lack of available supply. I had to ask all the the computer stores in our place and I was lucky to find one 1Gb of RAM with the correct specs for our laptop.

Once we completed the laptop RAM upgrade, we immediately noticed that the laptop booted up faster and went through websites and application easier than before the upgrade. We were pleased with our decision to just install laptop RAM instead of buying a new computer which is really outside our budget.

Refurbished Cellphones

Refurbished CellphonesJust about a year ago, my mother-in-law bought from a store selling refurbished cellphones. She got a Samsung which looked so beautiful, it looked like it was still brand new. On top of that, since it was already a used cellphone, she got it at a very low price. She was very delighted with her purchase, until several weeks later when problems started to happen one after another...

First, her battery died on her. So we had to buy a brand new battery for it. Then, just after a short time, her refurbished cellphone just wont turn on. We brought to the repair shop to have it fixed. It turns out that the problem was the actual motherboard, where all the electronic components are attached. The cost of the parts and repairs, combined with the new battery and the cost of the intial phone purchase, was actually close to the cost of just buying the same model but as brand new.

We learned a big lesson that day.
We decided not to have it repaired anymore. What we actually thought was a good deal at first, was actually too good to be true. Refurbished cellphones don't have the warranty and the seal of quality from the original manufacturers. So that means you can get lucky, but you probably won't.

How about you? Have you ever bought refurbished cellphones? Did you have the same experience? Drop me a line.

New iMac Mac Mini and Mac Pro

New iMacCheckout the new iMac Mac Mini and Mac Pro from Apple. Man, these are really beautiful machines! My dream is to have either the large screen iMac or the Next-Gen Mac Mini. Someday, when my Google Adsense finally picks up, I may have some budget for it.

New, Faster iMacs, Mac Pros and Mac Minis Now Official
By Charlie Sorrel

Article Source: Wired.com blogs

Apple has announced enough new Macs to merit a keynote from, well, from whoever does them these days. Instead, all we get is a press release. Here we run down the spec-bumped desktop machines. Those of you who recently bought MacBooks can breathe easy — no changes to the notebook lines have been made today. UPDATE: Yes they have. The $2500, 15" MacBook Pro gets a faster 2.66GHz processor and the option to upgrade to 2.93GHz for an extra $300.

iMac

First we have the new iMac. The leaked specs we posted yesterday appear to be dead on: One 20” and three 24” models, with Intel Core 2 Duo (not quad) processors ranging from 2.66GHz to a blistering 3.06 GHz. The machines ship with either 2GB or 4GB RAM and can be upgraded to 8GB.

All the iMacs now have the faster NVIDIA graphics — the two cheaper models have GeForce 9400M integrated graphics and the GeForce GT 120 with 256MB memory and the GeForce GT 130 with 512MB. Needless to say, these are some fast machines. Otherwise things remain much the same, except for a lowering of prices: the 24” iMac now starts at a reasonable $1500. At the top end you’ll pay $2200, but this machine will out perform even fairly recent Mac Pros.

Mac Mini
Also rumored was the Mac Mini, and the leaked specs are again accurate, right down to the photograph we saw detailing its five (count ‘em!) USB ports. Apple is touting this as a green machine, calling it “The world’s most energy-efficient desktop computer” and at rest it apparently sips just 13 Watts.

That’s good news for the whales and the rain forests, but even better news for the home cinema buff — low power means that the fans stay off, which means the Mac Mini stays quiet. And home cinema is where this thing is aimed: The back sports two kinds of display outputs — Mini DVI and MiniDisplayPort. It also has FireWire 800 in there.

Inside, the differences between the the two models is slight. Both have a 2.0 GHz processor, both have the new NVIDIA GeForce 9400M integrated graphics and both have a SuperDrive. They only differ on memory size (1GB vs. 2GB), hard drive size (120GB vs. 320GB) and graphics memory (128MB vs. 256MB). They’ll cost you $600 or $800.

Mac Pro
Finally we have the new Mac Pro, which features Intel’s latest Nehalem processor. This can be had in quad-core or 8-core variants. Both models come with NVIDIA GeForce GT 120 cards with 512MB. Memory is either 3GB or 6GB and both come with a 640GB HD and the display options have grown to Mini DisplayPort and dual-link DVI.

But the Mac Pro is all about the expandability. Here are the maximums: 32GB RAM, 4TB storage, three PCI-X slots and two 2.93GHz Quad-Core Intel Xeon processors. The interior design has also been tweaked to fit it all in.

Stock models are priced at $2500 and $3300. As is now traditional, I specced out the most expensive options. How much? Leaving out extra software, I managed to hit $14,150. Ouch.

Solid updates all, and no real surprises. The only odd thing about this whole affair is that Apple can release so much new hardware on one day and not hold even a press conference. Still, that might be a waste of money. After all, it’s Apple. We’ll all be writing about it anyway.

Amazon's Notebook Bestsellers

Netbooks are the smaller and cheaper alternative to laptops. They perform the most basic functions like surf the web and store pictures. They have enough power to perform 99% of what ordinary people do with their computers.

There was a time when netbooks were still sold under the "laptop" category. Now the netbook has its own subcategory separate from laptops. Amazon has actually sold more netbooks than laptops so far this year.

I just browsed through Amazon.com's bestselling laptops/netbooks and here's what I got:

1. ASUS Eee PC 1000HE 10-Inch Netbook (1.66 GHz Intel Atom N280 Processor, 1 GB RAM, 160 GB Hard Drive, 10 GB Eee Storage, Bluetooth, XP Home, 9.5 Hour Battery Life) Black

2. ASUS Eee PC 1000HE 10-Inch Netbook (1.66 GHz Intel Atom N280 Processor, 1 GB RAM, 160 GB Hard Drive, 10 GB Eee Storage, Bluetooth, XP Home, 9.5 Hour Battery Life) Blue

3. Acer Aspire One AOD150-1165 10.1-Inch Netbook - Sapphire Blue

4. ASUS Eee PC 1000HA 10-Inch Netbook (1.6 GHz Intel ATOM N270 Processor, 1 GB RAM, 160 GB Hard Drive, 10 GB Eee Storage, XP Home, 6 Cell Battery) Fine Ebony

5. Acer Aspire One AOA150-1126 8.9-Inch Netbook (1.6 GHz Intel Atom N270 Processor, 1 GB RAM, 160 GB Hard Drive, XP Home, 6 Cell Battery) White

6. Toshiba Satellite A305-S6908 15.4-Inch Laptop

7. Samsung NC10-14GB 10.2-Inch Netbook (1.6 GHz Intel Atom Processor, 1 GB RAM, 160 GB Hard Drive, 6 Cell Battery, XP Home) Blue

8. ASUS Eee PC 900HA 8.9-Inch Netbook (1.6 GHz Intel ATOM N270 Processor, 1 GB RAM, 160 GB Hard Drive, 10 GB Eee Storage, XP Home) Black

9. Acer Aspire One AOA150-1672 8.9-Inch Netbook (1.6 GHz Intel Atom N270 Processor, 1 GB RAM, 160 GB Hard Drive, XP Home, 6 Cell Battery) Pink

10. Apple MacBook MB466LL/A 13.3-Inch Laptop (2.0 GHz Intel Core 2 Duo Processor, 2 GB RAM, 160 GB Hard Drive, Slot Loading SuperDrive)

With 8 out of 10 of the bestsellers in Amazon, the netbooks are apparently dominating the market. I will not be surprised to see this trend continue for a long time.

Personally, I am torn between buying an Apple Macbook and an Asus Eee PC 1000HA. Oh well. Better to make the decision later when I already have the money to spend...

Buying Amazon.com's Kindle 2.0?

Kindle: Amazon's Wireless Reading DeviceAmazon Kindle
Plan on buying Amazon.com's Kindle 2.0? As for myself, I don't plan on getting one because it is still too expensive for me. Also, I think the technology is still in its primitive stages. I think we will get to see more capable machines with cheaper price tags in the near future.

Look at some reasons to buy or not to buy Kindle 2.0 from crunchgear.com.

10 reasons to buy a Kindle 2… and 10 reasons not to

by John Biggs

Having used both Kindles 1 and 2, I thought it would helpful to list where the new Kindle excels and where it falters. The dead tree book will never die - I think it will even have more longevity and popularity than the boutique appreciation of vinyl records - but our generation will be the last to use “books” as our primary reading systems. Expect ebooks to hit colleges in perhaps five years and high schools and grade schools in about 7. That said, should you buy a Kindle now? Why and why not?

10 Reasons to buy a Kindle 2


1. It’s great if you travel. If you travel, the Kindle is a godsend. I’m the kind of guy who stocks up books for even short trips, fully expecting to finish War and Peace, Notes from Underground, and four Clive Cussler novels on a plane trip from Pittsburgh to Columbus. With the Kindle you have a full complement of books available at any time.

2. You can put anything you want on it. You can easily email DOC, TXT, and PDF files to your own Kindle email address for conversion to the Kindle - but that costs 10 cents.

3. It looks great. The Kindle 2 is an amazing improvement over the Kindle 1. If every manufacturer took cues on build quality and product life cycles from Amazon, we’d all be better off.

4. It feels great. This new version has excellent button placement and is thin enough to cut cheese. It’s eminently portable.

5. Almost any book at any time. Except for a few esoteric reference books I’ve found just about everything I need on the Kindle store. As more and more publishers go ebook - and I think an iPhone Kindle reader will truly blow the last bottlenecks out - this excuse will become ineffective.

6. It works in inclement conditions. I was in Mexico with the wife and kids and I wanted to test the Kindle out near the pool. Three books later and I felt like the laziest high-tech maven in the world. The ladies next to me brought twenty softcover novels with them and all of them got wet and messy. The Kindle worked like a dream.

7. The bookmarking and highlighting systems are vastly improved. The original Kindle had two methods for note-taking: you could select text and add a note or you could add a book mark. The new system refines those considerably and adds visual feedback whenever you take a note.

8. The dictionary is now in-line. When you move to a word, its definition appears at the bottom of the page. If you wanted a definition before, you had to pop out to a separate page.

9. You can almost see and understand the illustrations in 16 greyscale shades. Note the “almost.” However, it’s better than 4 shades, which was abysmal.

10. It is the future. Sorry, it is. Amazon nailed the ebook and they’re going to own the space for the next few years. Maybe they’ll pull a Netflix and sell the software to OEMs, which is fine by me. But ebooks are what we’ll be reading while we rocket to Mars in 2050. Or we’ll have our robotic concubines read them to us.

10 reasons not to buy a Kindle 2


1. It’s bad for research. I’m working on a book right now and I wanted to use the Kindle for all of my research. Sadly, this is almost impossible. The book is a physical object - you can move through it, skimming for notes and important points - and there is something in our education that gives us a sense of space inside a book. I don’t quite know how to explain it, but you know how you can pick up a book and show someone what you’re looking for in a few page turns? You know it was halfway through, maybe a third of the way down the page, and it was near another set of words. The Kindle is not conducive to that kind of mental map-making… yet.

2. It’s horrible for reference. Don’t buy a Kindle of you just read programming manuals. Programming manuals offer something different. While it seems counterintuitive that a document you can search programatically wouldn’t be good as reference material, you’re better off looking up function calls on a website and using the physical book as a guide to building your programs. This is a corallary of point 1, above, so this could change.

3. The Kindle is flimsy. You’ll go through your day thinking you will break your Kindle. You don’t fit that much screen on a thin device that is meant to be thrown into a bag without a care and not risk cracking it. There will come a day when you open your bag and see that your Kindle is dead, even in its case. It’s not your fault. Say it with me: it’s not your fault.

4. It’s not ready for students. Add points 1, 2, and 3 together and you come to the conclusion that this is not ready for students. This may be a good device for English classes requiring lots of long novel reading, but as an education tool it isn’t quite there.

5. The net connection doesn’t work internationally. For some reason last year I was convinced the Kindle had Wi-Fi built-in. I was trying to get on the Internet in Warsaw, Poland and I kept looking for that Wi-Fi button. Then I remembered - no Wi-Fi. And I cried. How I cried, my friends. Then I downloaded the Kindle book onto my desktop and dragged it over via the USB cable. So that’s, in essence, your international solution.

6. No SD slot. While the Kindle can easily hold 1,500 books, what if you’re the kind of person who likes to keep everything in its right place? Maybe you want to make a book playlist? Maybe you have 1,501 books? I don’t know. Sadly, the Kindle doesn’t allow for memory expansion. Not a big deal, but to some it’s a bad thing.

7. Flight attendants will tell you to turn it off on take off and landing. You can’t explain that it’s epaper and uses no current. You just can’t. It’s like explaining heaven to bears.

8. It contains a battery. Remember, Reader, the Kindle is mortal. It will die on you when you don’t have your charger.

9. It’s bottom heavy. The internal battery makes the device want to plop face down on your chest. I read it last night when I was sleepy and it kept getting ready to fall on me.

10. There’s just something about a dead tree book, isn’t there? It’s nice to pop into the airport news stand and pick up a novel. It just is. I’m sorry.

Kindle 2 Hands On

Kindle 2 unboxing and hands-on
by Joshua Topolsky


We've already gotten a chance to play with the Kindle 2, but there's nothing like getting one delivered to your door and cracking it open. As with the first version, Amazon has done a masterful job with presentation and packaging. We're going to be delivering a full review of the device in just a bit, but for now, feast your eyes on the galleries below!

Update:
Added a few pics of the case it comes with after the break!









Wired.com product review
Kindle 2 Brings Books Closer to e-Nirvana
Reviewed by Steven Levy

The most notable feature of the Kindle 2 (Amazon.com's long-awaited update to its groundbreaking but somewhat flawed electronic reading device) is that it's possible to pick it up and not turn the page. This sounds like faint praise, but anyone using the original Kindle quickly found the oversized buttons covering both sides of the device made grasping it a delicate, stressful task -- kind of like picking up a sea urchin. Anything less than perfect finger placement would lose your place.

Not so with the Kindle 2, which fixes that problem and a host of others through thoughtful, businesslike improvements and innovations.

Are the improvements big enough for the Kindle 2 to spark an iPod effect, causing bookstores to shutter, forests to grow unchecked and the tomes on our shelves to disappear, replaced by plants and bobble-head dolls? Not any time soon.

The evolution toward e-reading devices as the dominant means of reading books will be a drawn-out and complicated affair. It will require screen technology with inexpensive, high-resolution color, multitouch and flexible displays. These are all features that the Kindle, as well as competitors like the Sony eReader, are still waiting for. A mass-market solution will also involve pricing that acknowledges how much cheaper it is to distribute books digitally; currently Amazon sells e-books for about half the price of their hardcover equivalents. But for now, the Kindle 2 is the closest thing to this magic formula.

The Kindle 2's page-turning buttons are smaller and more smartly situated than the first version's. It's harder to press them by mistake. In fact, by requiring you to depress them with authority, they're a little too hard to press -- it would be nice if the reader could adjust the action a little. But overall, it's a problem solved.

closeup of Kindle 2 buttons

The strengths of the device are the same. The dense, readable display and paperback size allow readers to sink into an author's world just as they do with a physical tome. But this "book" is augmented by digital technology, allowing you to store hundreds of manuscripts, search through them, and look up words in an onboard dictionary, on the web or through Wikipedia. It also has a free wireless connection to the Amazon Kindle store -- now hawking 230,000 books (as well as magazines and newspapers).

The day after I got the new Kindle I boarded an airplane and before the doors closed, browsed the store and purchased Thomas Perry's thriller Runner. The book uploaded within 30 seconds and I was absorbed in it for the entire five-hour plus transcontinental ride. When I finished, the 10-ounce device had a shelf-full of books and magazines -- as well as a manuscript of an article in progress -- waiting for me.

I could have done that with the original. But while Kindle 1.0 won a substantial following, it had many of the problems you'd expect from a novice player in consumer electronics. Amazon has clearly been hard at work addressing the difficulties, and has succeeded to the point where some early buyers will be kicking themselves for premature adoption.

The most dramatic changes are in the physical design. Abandoning the quirky shape of the original, which was meant to evoke the form of a real book, the designers boiled down the shape to a pencil-thin (.36-inch) slab, which feels completely natural in hand. Though you can buy an "official" $30 leather cover (it has special hooks that keep the device in place, something that was missing in the original), I found it most comfortable to read bareback. But if you're into playing it safe, I'd recommend one of the third-party neoprene cases available on Amazon.com.

The screen is the same size as Kindle 1.0 -- a legible 6-inch monochrome e-ink display that requires an external light source to view -- just like a paperback. But version 2.0 displays images in 16 grayscale shades, far better than the previous version's pathetic four. Though the Kindle is definitely not the ideal device to show off pictures of the family vacations, this quality bump makes the difference between getting the impact of a chart or photo in a book, rather than having pictures look like fifth-generation Xerox copies (as they did in the original).

Kindle 2 in hand

Another giant step is the replacement of the original's awkward cursor-control wheel with a simple five-way button that you tilt in the direction you want to cursor to move, or press to select an item. It works so well you wonder why the Amazonians didn't think of it first. Those of us spoiled by multitouch still wish that the Kindle had a hands-on display so we could turn virtual pages with the swiping gesture that the gadget gods intended.

One of the weakest aspects of the original Kindle was an abysmal interface for reading newspapers: it required painstaking back-and-forthing to get a grasp of contents. This new software still isn't perfect -- again, a touchscreen would help -- but it now provides a logical path for navigating the Times and other publications.

The Kindle 2 is zippier, with pages turning 20 percent faster (yes, you can tell the difference). It has more memory (2 gigabytes, enough for storing more than 1500 books onboard). And it flaunts a more powerful built-in battery: Amazon claims that the Kindle lasts four to five days with the wireless on (I got 4.5 days in my first test) and up to two weeks with it off. After a week of limited wireless, my meter is around 50 percent. Amazon also says that after 500 charges, it will hold 80 percent of its original juice. That means that most users won't have to replace the battery (a $60 procedure) for about a decade or so.

One feature in the new Kindle I couldn't test, because Amazon furnished me with a single test unit, is a new feature that allows you to synch your reading among other Kindles and other mobile devices that Amazon may support. This means you could read 50 pages of Revolutionary Road, shut the device off, and when you open the Kindle application on your phone later, it will start you on page 50. Read 10 pages between appointments, and when you revisit your Kindle, you'll start on page 60. The logical partner for this scheme, of course, is the iPhone, and it would be a disappointment if a match weren't made in the app store.

This Kindle 2 has generated some controversy with its experimental "read to me" function that transforms any book into an audio book. I found the text-to-speech implementation perfectly listenable, with only a slight electronic accent (the computer-generated reader apparently is a distant cousin of the Lost in Space robot). The feature would be even better if the built-in speakers weren't on the back of the device, muffling the sound if you place it screen up on a flat surface. But if you can sync the Kindle 2 into your car radio, you can catch up with your reading while you commute. Not so enthusiastic is the Author's Guild, which claims that the feature might lessen the value of members' audio rights.

But text-to-speech works just as well with your own content -- you can upload Word files into your Kindle for a dime apiece.

The new Kindle is currently priced same as the old one, $360. Considering that it's an engine for buying books directly from one supplier -- Amazon.com -- that seems too high. On the other hand, it's hard to fault Amazon for what it charges when it can't fulfill demand at the current price. Also consider that the books you buy from Amazon are limited by digital rights management rules imposed by the publishers. You may invest thousands of dollars over the years in a library that your friends can't access and your heirs can't sell to second-hand dealers.

Looking over the horizon, it's clear that Amazon's biggest competitor in selling digital books will be Google, whose recent agreement with publishers and authors will make it a virtually exclusive seller for millions of books in copyright but not in print. But right now at least, the Google and Amazon formats aren't compatible: I was unsuccessful in getting a PDF of a public domain book downloaded from Google to appear in readable form on my Kindle.

Overall, the Kindle 2 addresses the key problems with the original, boosts performance and points to some interesting directions. Now we're a little bit further down the road toward e-book Nirvana.

WIRED The best e-reading system on the market. Welcome improvements to aesthetics, more functional industrial design, better graphics and longer battery life. Sleeker than the original: A third of an inch thick and 10 ounces.

TIRED Quite expensive. Book content shackled with DRM. Interface is improved, sure, but it could be even better.
