The wireless Internet laptop allows you the freedom to roam away with AC outlets. But it is the built-in Wi-Fi wireless feature often found in Pentium M laptops that gives you the power to connect to the Internet and send and receive email from wherever you are, without wires. Hotpots are appearing everywhere.

Wireless Internet laptop networking has made the leap from dream to reality. Nearly every mobile device on the market features some kind of wireless connectivity or at least support for it. Sorting through the available standards may seem tricky, but it is not. Basically there are two kinds of wireless connectivity : Blue tooth and Wi-Fi.

Wi-Fi, also known as 802.11, is the older, more established wireless standard. It is also faster and has a longer range than Blue tooth. This extended range opens a vast range of possibilities. Many public areas can be outfitted with WiFi antennas to extend the wireless Internet laptop operating range for use in public areas. Using WiFi for Internet access from your laptop, you can go on line and send email from airports, hotels and coffee shops. This will be the fastest-growing segment of WiFi service, as more and more travelers and mobile professionals seek fast and secure Internet access wherever they are.

Wireless Internet Laptop Bluetooth is meant for short range jobs, such as connecting a PDA to a cell phone or a cell phone to a laptop. It is great for syncing address books and small files between devices. Blue tooth is not well suited for data networking because of its limited range and lower speeds, but it is useful for handheld and mobile phone accessories.

Laptops, Video Systems and Audio Systems have lots of peripheral devices that connect by wires and cables. If you have looked at back of your computer desk, it can be noticed that it looks like a major tangle of wires. Each wire has a particular connector and each connector follows certain protocols. Blue tooths aim is to get rid of those wires. Companies that manufacture PC, notebooks, entertainment systems and other electronic devices have realized that the enormous array of cables and connectors involved in their products will confuse most consumers. Setting up PC, laptop and home-theater systems can be difficult when the person buying the equipment has to learn and remember all the details of what wire goes from where to where.

The Windows Blue Screen of Death (BSOD):
Ah— the dreaded Blue screen of Death. When your windows operating system crashes, you will get the dreaded Blue Screen of Death, which is a stop error. Only, in this case, it means that your operating system has totally crashed.
Most people don’t realize that the Blue Screen of Death is actually a protective mechanism that the operating system uses to prevent irreparable damage to the system files by immediately shutting down the entire system the instant it discovers a critical system error. If it shuts down fast enough, damage will be avoided. If not, you could end up having to reinstall your operating system depending on what caused the error. The picture below shows a BSOD error.

What Causes the BSOD Error?

The primary causes for BSOD errors are:

• Poorly written device drivers. In this case you should update your drivers.
• Malfunctioning hardware such as bad memory, power supplies, overheating, etc
• Two applications attempting to write to the same memory location simultaneously because a record lock failed
• Invalid / corrupt registry entries. You can repair this with a good registry cleaner.

When the encounters a fatal error, it will send diagnostic information to the display screen right before it reboots the system. In many cases, the reboot will clear the problem and the system will run normally.

What Does All That Stuff on the Screen Mean?

Each stop error is paired with a description of theerror and an eight digit hexadecimal error code number. You can use thisinformation tofigure out what is ciausing the problem. Let’s dissect the error screen above. A copy is shown below.

In the first red box, it says that the spcmdcon.sys file has cause a PAGE_FAULT_IN_NONPAGED_AREA. That is the type of error the system encountered. This error occurs when the data requested from memory by the processor cannot be found at the location address provided. This can be caused by defective RAM including main memory, video RAM, L2 or L3 cache, etc.
The second red box contains the technical information about exactly what memory locations are involved.

Can You Fix a BSOD Error?

In the case above, there is a good chance that one of the memory modules has some bad blocks. Even if the machine reboots and runs fine, you should get the memory tested and replace it if necessary or at least use a repair utility that can mark the block that are bad so the system doesn’t use them again.
If there is nothing wrong with the hardware and the problem keeps reoccurring, you will need to do an operating system repair using the repair console or you can just reinstall the operating system.
Some Common BSOD Errors are:
IRQL_NOT_LESS_OR_EQUAL – a kernel mode process tried to access restricted memory, which means memory reserved for processes that have a higher IRQL level than it does.
KMODE_EXCEPTION_NOT_HANDLED – an illegal or unknown processor instruction was encountered
PAGE_FAULT_IN_NONPAGED_AREA – the requested data could not be found at the supplied address

INACCESSIBLE_BOOT_DEVICE – the system cannot access the boot sector which usually means there is a hard drive disk  problem or a boot sector virus.
UNEXPECTED_KERNEL_MODE_TRAP – caused by defective or mismatched memory, a bad CPU or a bad CPU fan and the processor  is overheating
DRIVER_POWER_STATE_FAILURE – caused by a defective device driver
THREAD_STUCK_IN_DEVICE_DRIVER – a bad driver is causing an infinite loop
NTFS_FILE_SYSTEM – the file system is not working properly
UNKNOWN_HARD_ERROR – one of the registry hives could not be loaded into memory usually because of a hard disk failure or a corrupted registry hive
STATUS_IMAGE_CHECKSUM_MISMATCH – usually caused by a damaged paging file but can occur for other reasons

Conclusion

The BSOD, especially if it reoccurs, usually means there is a serious problem that will eventually require you to replace hardware or to reinstall the operating system. In fact, many times it may be necessary to do both … replace the faulty hardware and then reinstall the operating system.

Hi guys,

This guide already well known to the world, but still worth to be shared. :) Let me describe about the issue on the title of this post. "Red X mark on the wireless signal bar on taskbar".

The issue : 

>>>> Occur in windows 7 <<<<

1) When you click on the signal bar, you can see available wireless connection.

2) You can connect to the network you see.(provided that the wireless network not password protected and

    available)

3) The RED X mark suppose to mean that
your Wireless Adapter is DISABLED.

Now you see the issue. Your computer giving you a false icon / falsenotification. It should be a wireless signal with orange X symbol.(If youre not currently connected to any network).

What cause the wrong icon???

1) Some suggested that the icon doesnt belong to the wireless adapter but it belongs to your LAN adapter.

    1.1) Delete other Adapter present in the Change Adapter Setting except LAN adapter and Wireless

           adapter.  Click on the Wireless Signal Bar on your taskbar > Open Network and Sharing Centre > On the left tab, click Change Adapter Setting > Right click on the LAN adapter >

           Disable

    1.2) You need to disable and then enable your LAN adapter.

            Click on the Wireless Signal Bar on your taskbar > Open Network and Sharing Centre >

            On the left tab, click Change Adapter Setting > Right click on the LAN adapter > Disable

If you lucky, step 1 should solve the problem. But if step 1 didnt solve the problem,

2) Go to Device Manager and uninstall your wireless driver but dont delete(dont tick the remove driver

    box) the driver. After uninstall, restart your laptop.
