The new MacBook Pros now all come with sealed batteries. This was just once the territory of the mighty 17 inch model. Not anymore. The recent refresh brought that technology to its smaller siblings, the 15 inch and the recent addition to the MacBook Pro line-up the 13 inch.

According to Walt Mossberg who had the chance to test both the 13 and 15 inch MacBook Pro and put it through the paces of his own battery test, both laptops performed well. The 13 inch lasted a slighty below the 5 hour mark while the 15 inch was 21 minutes above the 5 hour marker. This says well considering no power saving feature was turned on and the screen brightness was cranked up. In normal usage, expect battery life to be even slightly higher.

I for one was at first skeptical of the notion that I can’t replace the battery of my laptop. However looking back, ever since I’ve owned a laptop, I’ve never bought a spare battery. Hmmm… I guess I just like the thought that I could replace it if I wanted to. Mossberg cites in his article that only less than 5% of consumers actually buy spare batteries. This figure was from NPD, a research firm. I would believe that this figure is close to the truth.

I guess we just need to let go of our need to control things and trust that technology works. Apple was able to increase battery size and life in its MacBook Pro line of computers without adding weight or heft. I guess its a decent trade-off to the fact that you can’t replace it yourself. Apple also claims that their batteries will last up to 5 years. So by the time it’s time to change batteries it’s also time to change computers.

So we’ll see in the days to come if indeed sealed batteries are the way to go.

Intel is now pushing it’s dual core technology to ultra thin notebooks as announced this week. The dual core processor are the Celeron 740 and the SU2300 which features a core clock of 1.3 GHz and 1.2 GHz. Both processors also has identical 1MB L2 cache, 10W TDP and 800MHz FSB.

As per announcement:

Intel recently added two dual-core CPUs into its CULV platform targeting entry-level ultra-thin notebooks – the Celeron 740 and SU2300, according to sources at notebook makers.

The Celeron 740 and SU2300 CPUs feature core frequencies of 1.3GHz and 1.2GHz, respectively, while both share the same 1MB L2 cache, 10W TDP and 800MHz FSB.

The dual-core Celeron CPUs expand Intel’s CULV lineup from originally three levels into four – single-core entry-level, dual-core entry-level, single-core performance and dual-core performance.

The sources said single-core and dual-core entry-level CPU-based ultra-thin notebooks will have a chance to drop NT$2,000-3,000 (US$61-91) starting August, while the ASP of single-core Celeron 723-based models will be able to reach market expectations for ultra-thin notebook priced at NT$20,000-22,000.

This is good news as the next step is to bring dual core to the netbooks market. Smaller computers are going to get powerful and hopefully cheaper.

I recently got a new battery for my laptop. I’ve been working without a useful battery for quite some time now. I couldn’t even get all the way through an initial startup without getting a critical battery alert if I wasn’t plugged in. Now I’m happy to say I’ve got a new battery and can truly work wirelessly again.

After checking a variety of websites I ended up at DuracellDirect.com and purchased a replacement battery for my laptop. After receiving my battery, on the paper that was included with the packaging it gave me some tips on prolonging the life of my new battery. Among those tips were to not charge it unnecessarily. It recommended that when computing on direct power by being plugged into the wall, to remove the battery from the laptop.

I began to think that would be a great idea. That was quickly followed by asking why there wasn’t a software switch within my operating system to disconnect my battery from being charged when the computer was plugged-in. After typing that sentence I thought to myself why this couldn’t be automatic when the computer knows it’s plugged-in.

Does anybody know if this is an option at some point on some system in the future? If it really helps batteries, why wouldn’t that be a standard feature these days?

I’ve realized that my last Tech Channel Roundup was nearly a month ago and I’m guilty of it. So, bear with me as I overload you with a number of interesting links that I found in some of the sister blogs.

Milo discovered a product especially useful for enterprises of all sizes called Nightwatchman, a good news that Microsoft didn’t lay off anybody in the Vista team. I knew that they didn’t touch the Silverlight team, but frankly I’m surprised about this because Vista hasn’t been very profitable to Microsoft. Or has it? One bad news is the Windows 7 minimum requirements. It may not be a good experience to try it on my netbook which just meets the minimum requirements and my laptop which is old enough to even miss the minimum. But if anyone is interested, you can get the Windows 7 look into Windows XP. He also found a couple of amusing videos, one called “how to say i love you.” and another a confirmation of love, a marriage at Taco Bell. Recession, aye?

Jason found a few websites that can assist you in unique ways: one for helping educate your kids, one a calendar to help others, and another to scan your computer online. He covered a lot of Windows Powertoys, a mobile media browser and found another reason to continue loving Zune. He also has a couple of how-tos for selecting non-linear text in a word document and sharing Outlook calendar availability. One bad news, I mean another one, is that Microsoft is shutting down MSN Groups.

Claire thought out loud about the gap between Linux and mainstream users, learnt something new about less (which all you Cygwin users may find useful), discovered a wonderful browser called Kidzui which attempts to make the Internet a more kid-friendly place.

Juan wonders whether the Mac is not invincible anymore and whether Apple really needs to make a netbook. He is glad to find a symbol cheat widget and an app that can save his day with a bunch of drawings. The latter isn’t my cup of tea. He along with Jayvee found out about Apple’s stand on piracy.

I use an old Lenovo T60 and like to grumble about its performance. I’m sure the feeling is mutual. I also use a docking station at work. Makes life simpler. Recently, I had a problem with the way it powers the laptop.

The laptop had been docked, but the power supply unplugged due to some neighbourly reasons. When I restarted the laptop, it simply shutdown. When I powered it again, it brusquely answered with a series of flickers across three of its LEDs (power supply, battery life and something else that I don’t remember now) in a most NSFW manner. The laptop won’t start. I had read it as a signal to get a new laptop.

Upon undocking the laptop, going home, and powering it on again, it worked! Was my laptop for once being helpful? Enabling me to idle away my time in the office?

I was naturally suspicious. Upon further investigation, the following has been established: A docked laptop uses the power provided through the docking station while booting and won’t use the battery power. An undocked laptop, and a docked non-booting laptop can use the battery power.

Do you have more light to shed about this issue? Do you think it is a sweeping generalization?

eWeek had a great article/annoying slide show about the top 10 security risks that your users pose to your organization. One interesting thing I noted was with all of the increases in security (firewalls, IPS/IDS, NAC, password hardening, etc) in today’s organization, most of these are not even looked at.

Think about the easy of someone to walk out with their laptop and have it lost on the train (with not encryption)… Or someone with P2P software on their machine (that is sharing out their entire C drive)… Or worse yet, wifi (without separating it from the rest of the network) that isn’t secured with WPA2… Oh the horror!

1. USB Flash Drives
2. Laptops
3. P2P
4. Web Mail
5. Wi-Fi
6. Smart Phones
7. Collaboration Tools
8. Social Networks
9. Unauthorized Software Updates
10. Virtual Worlds

What are some of the other security risks you can think of that companies face?

As an IT guy, I very rarely leave my cell phone, laptop, Blackberry or other computer-related device behind. I hate the though of going somewhere without being connected to the rest of “my world”. The internet is supposed to be a never-ending place. And I never want to be without it just in case it does end. I would have to be the first to hear it.

When I started at Rohm and Haas, I was without a phone, desk, computer or login accounts for 3 days. This was one of the strangest feelings I’ve had since learning to drive a car, or the first time I partied too hard in college. It wasn’t fun. Sure, I wasn’t stuck over a toilet or driving like a granny, trying to not go over the speed limit, but it was almost painful.

I’m used to being connected to anyone and everyone at the push of a button. Now, I had to pre-plan what route I was going to take (no Google Maps), who I might need to call (no company directory at hand) and what I had to do (no Blackberry connected to my datebook). I think in the end though, it was good for me. I learned over the past couple months to not always stare at my email, respond to them in near real-time and to live on the Internet (especially Twitter) day in and day out.

With this, I ask you, do you have nomophobia? If so, what do you think you should do about it? Face your fears or live with it?
