Do you need to repair your laptop?
When you contemplate repairing your own laptop keep in mind that once you open the casing you could be voiding any and all warranty coverages. A certified repair technician will be able to tell quickly if a laptop has been opened and the internal components tampered with or changed.
Laptop repair isnt always easy. If the laptop isnt under warranty and you dont feel comfortable replacing some of these parts yourself, youll have to find a professional to do it.
If you want to repair a laptop by yourself you should have first of all the disassembly manual, pictures and videos ordered by the manufacturer. Once you have the laptops disassembly manual youll discover that a laptop is made up of numerous delicate and small chips and other technical elements with minute details. If one of these innumerable and delicate technical elements is subjected to malfunctioning, then the whole of the laptop will stop functioning. If a problem is allowed to persist in the laptop, it might even damage and cause dreadful things that might even prove to be permanent. Therefore it is always desirable to treat the laptop with utmost care and pay full attention to repairing any sort of problem in the machine.

People have more flexible time due to wireless network. Thanks to the invention of wireless. People can now work from home while taking care of their kids or doing house works. No more stress from traffic jam anymore. Is this great?
Well, there is something you should realize. Working from home while using a wireless local area network (WLAN) may lead to theft of sensitive information and hacker or virus infiltration unless proper measures are taken. As WLANs send information over radio waves, someone with a receiver in your area could be picking up the transmission, thus gaining access to your computer. They could load viruses on to your laptop which could be transferred to the company's network when you go back to work.
Believe it or not! Up to 75 per cent of WLAN users do not have standard security features installed, while 20 per cent are left completely open as default configurations are not secured, but made for the users to have their network up and running ASAP. It is recommended that wireless router/access point setup be always done though a wired client.
You can setup your security by follow these steps:
1. Change default administrative password on wireless router/access point to a secured password.
2. Enable at least 128-bit WEP encryption on both card and access point. Change your WEP keys periodically. If equipment does not support at least 128-bit WEP encryption, consider replacing it. Although there are security issues with WEP, it represents minimum level of security, and it should be enabled.
3. Change the default SSID on your router/access point to a hard to guess name. Setup your computer device to connect to this SSID by default.
4. Setup router/access point not to broadcast the SSID. The same SSID needs to be setup on the client side manually. This feature may not be available on all equipment.
5. Block anonymous Internet requests or pings. On each computer having wireless network card, network connection properties should be configured to allow connection to Access Point Networks Only. Computer to Computer (peer to peer) Connection should not be allowed.
Enable MAC filtering. Deny association to wireless network for unspecified MAC addresses. Mac or Physical addresses are available through your computer device network connection setup and they are physically written on network cards. When adding new wireless cards / computer to the network, their MAC addresses should be registered with the router /access point. Network router should have firewall features enabled and demilitarized zone (DMZ) feature disabled.
All computers should have a properly configured personal firewall in addition to a hardware firewall. You should also update router/access point firmware when new versions become available. Locating router/access point away from strangers is also helpful so they cannot reset the router/access point to default settings. You can even try to locate router/access point in the middle of the building rather than near windows to limit signal coverage outside the building.
There is no guarantee of a full protection of your wireless network, but following these suggested tips can definitely lessen your risk of exposing to attackers aiming at insecure networks.

It's easy to be confused by all the different options when purchasing a laptop computer. There are literally hundreds of models to choose from for all different prices.
The key to finding the right laptop for you is determining firstly what your needs are going to be, then determining how much money you are willing to spend.
There are some general factors to consider. The first would be the size of the laptop. Do you want an ultra portable laptop that's small and light weight or do you want something more like a desktop replacement while compromising on size and weight.
The second factor to consider would be the size of the hard drive on the laptop. Laptop hard drives are a lot smaller than desktop hard drives. A standard laptop hard drive size would be around 100gb. If you need to store large files such as videos then you would have to consider getting something with an upgraded hard drive.
The third factor would be the size of the memory. A standard size would be 256-512mb. Anything above this would cost extra. You would need to consider what you are going to use the laptop for. If word processing and web surfing is all you want to do then 256mb would be more than enough.
The final factor would be pricing. This is completely a personal choice but you do get what you pay for. Laptop prices have dropped dramatically these days and a laptop can be bought for as little as $1000. Considering a couple of years back you couldn't get a laptop for under $2000 this price isn't too bad. But of course it all comes back to your needs. If a high end laptop is what you need for picture or video editing then expect to be paying over $2500.
Buying a laptop doesn't need to be a difficult task. If you evaluate your needs first and choose carefully your new purchase will be a profitable one.
