It can be so annoying when at one moment you are sitting there working on your laptop, and then without any warning, everything on the screen just disappears and all you are left with is a blank screen! The laptop has mysteriously switched off.

Obviously, the first thing that you are going to check are all your leads to make sure the power cable has not come loose and inadvertently shut down your laptop. If this is not the case and your power adapter is still plugged in correctly, then the first thing to try is to unplug your adapter and try to do a power cycle.

This is a simple routine and can be done in just a few minutes. Firstly, unplug your laptop from the power source. Then remove any external devices if there are any plugged into your laptop.

Next, you need to remove your laptop’s battery. The next step would be to hold down on the power button for a few seconds.

You may be thinking at this stage that it is a bit of a silly thing to do when there is no battery in the laptop. There is, however, a method to the madness and it does work on a lot of occasions. By holding down the power button you will get rid of any static that has built up inside your laptop through excessive usage.

The static build up can cause the laptop to shut itself off at times. Sometimes you could use this routine if your broadband connection is playing up.

Once these steps have been completed, you should check your power source and your battery separately. If the laptop works with the battery and not the power source, the chances are that your power adapter is faulty. If the laptop works with the power source but not just on the battery, then you probably need a new battery.

Many laptops now come with built in error lights that tell you what the fault is. All you have to do is check the manual that came with the laptop and rectify the faults.

I have a friend whose company delivers IT training through remote lab simulation for customers all over the world. There was a problem with his newest product, which was a remote lab that included servers, shared storage, all in a real world virtualization set up. All of the users outside of the United States were having performance and latency issues.

Application delivery over the Internet is difficult when real-time interactions are required. This is because most applications are transmitted using the TCP/IP protocol, which is not optimized for speed, but for reliability. TCP uses dynamic windowing, packet sequence ordering, and packet retransmission requests in order to ensure reliable delivery of traffic. Because of the nature of TCP, applications transmission speeds start slow, then ramp up as long as no packets are dropped. As soon as packets are dropped, requiring a retransmission, the TCP window size shrinks, as does bandwidth.

The TCP/IP traffic that is transmitted worldwide goes through a number of different service providers and the peering points between them. At these peering points packets are dropped, and due to the nature of the TCP protocol the transmission rate slows down, causing poor application performance. Because of this, large organizations always use wide area networks instead of the Internet to deliver applications over long distances.

What my friend needed was a way to do application acceleration for individual users over the Internet, without installing any applications on their PCs, or putting any special hardware at their location at all. This is trickier than it sounds, since each of the reasons for TCP bandwidth limitation have to be addressed in order to have the application work properly. After the TCP protocol issues are addressed, then the information needs to be compressed at the head end and expanded at the remote site, which would effectively increase the available bandwidth for the application and then accelerate the application speed.

If he were to build out this, he would need a special acceleration server at his data center, and then another acceleration server at the Internet point of presence closest to each of its customers. The servers would have to be able to send packets to each other in a multiple redundant routes, perform compression using all the available current algorithms, have dynamic DNS to reroute the request to the server closest to the end-user, and the monitored all the time to make sure everything was working properly.

Knowing this type of system held would’ve been too expensive, obviously. In looking for a solution to his problem, he found a company that offers all these things as a service. The company already has over 50,000 servers in data centers worldwide, and have been doing this content acceleration for years. There are many different types of content that can be accelerated over the Internet:

- Faster virtual desktop infrastructure delivery.

- TCP/IP or HTML-based applications.

- Remote office and end-user VPN acceleration.

- Faster transfers of large files.

- WAN supplementation or replacement.

If this is a service that might apply to your situation, you should definitely look into speeding up the delivery of Internet traffic to your remote users. Among the applications that are being delivered, there is probably one that gets complaints about its performance, which would make it a good candidate for a test run. A good reseller with expertise in networking would be able to determine if an intranet application acceleration service would be right for you.

Amazingly, it’s now been a whole three years since I purchased my Xbox 360 unit. I went a while without it thanks to the dreaded red ring of death, but that’s another story that I’ll save for another day. For now, we’re going to focus on the good, which is the games. These have nothing to do with the hardware maker so I hold no grudges!

5- Tiger Woods golf. I’ve always been a huge fan of this series, dating back to my high school days when the game had first come out on the Playstation system. This is as real as it gets as far as golf games go, and amazingly, the game seems to improve each time they release a new version. I love it.

4. John Madden ’10. What can I say? I’m a sucker for the Madden series and beginning with last year’s game, EA Sports finally got it right. Madden is awesome, and Madden ’10 is naturally better than those versions from years past, so Madden ’10 gets my #4 vote as far as best Xbox 360 games ever go.

3. NHL 2K series. I absolutely love hockey, and I’ve been playing hockey on video game consoles ever since my elementary school days on the Sega Genesis. The fast-paced action of hockey games have always drawn me in, and the improved graphics and game play with each year keep me buying each new version every time it comes out.

2. NCAA Football. Very much like John Madden football, only a little more fun in my mind. This is the kind of game that might not be as realistic, but video games aren’t always meant to be. There’s nothing like racking up 100 or more points on the scoreboard, and NCAA Football is the perfect facilitator for that.

1- Rock Band. I think I’ve played more of this game than any video game I’ve ever owned since college. Whether I’m on the guitar, wailing away on the drums, or even singing (very occasionally), I’m always having a blast when I’m playing Rock Band. The ideal game for having friends over too!
