Bantayan Island

It is the island's most populous town, with a population of 71,655 people according to the 2007 census. It is bordered to the north by Madridejos and to the southeast by Santa Fe.
Bantayan Islands is geographically in the center of the Philippines. It is located at the northwestern side of Cebu and northeastern of Negros Oriental. It is a town of Cebu and is about 80 miles from Cebu City. The main Bantayan Island is about 7 miles wide by 10 miles long. About 20 of its islets stretch for another 5 miles long with some being accessible by foot from the main island at low tide. Mostly all the ships or ferryboats coming from Mindanao or south of Cebu have to pass by Bantayan Islands on its way to Manila. The Bantayan dialect is a mixture of native Cebuano, Ilongo (Negros), Waray (Samar), MasbateƱo, and Boholano, but it has words it can call its own such as “kakyop, sara, kag buwas“ (yesterday, today, and tomorrow).

Troubleshooting with POST Cards

A POST card is a diagnostic and troubleshooting device that is plugged into the expansion slots and tests the operation of the system as it boots up. These cards can be as direct memory access or they can be complex as ROM BIOS diagnostic tools that perform the advance level diagnostic tests. POST cards are generally used when the computer systems appear to be dead or the system is unable to read from the floppy or hard disk. The POST routines generally report two types of errors fatal and non fatal.

The fatal error stops and system and when the POST card observes non fatal errors, they should be read very carefully because the error code, which is indicated must be coordinated with the timing of the error message or beep code produced by the BIOS routines. Normally POST cards come with the LEDs (light-emitting diodes that produces code error signals and they identify any kind of problem.

Troubleshooting with Cable Testers

The most common hardware related compute networking problem is the bad cabling and RJ-45 connectors. There are a number of devices, designed for testing the network communication cabling. These devices include continuity tester, time domain reflectometer and cabling testers. Data cabling testers are designed to perform a number of different types of tests on the UTP/STP and coaxial cables. The master end of the cable tester is attached to one end of the cable and the load unit of the cable tester is attached to the other end of the cable. The master unit sends the signals through the cable and reads them from the load unit. When testing the cables, these devices normally detect the problems such as crossed-over wiring, broken wires, short connections and the cable connections that are improperly impaired.

Troubleshooting with Multimeter

Testing tools can help in isolating the hardware or software problems and digital multimeter is a most important tool for the electronic troubleshooting. Digital Multimeter and other electronic test instruments are available in analog and digital form and these instruments can be used to measure the electrical values of the voltage, current in miliamperes and resistance in ohms. These devices are known as Volt-ohm-milimeters (VOMs) for the analog signals and digital millimeters (DMMs) for the digital types. You can also check the transistors, capacitors, motor windings and diodes with the digital multimeter. In computer troubleshooting, most of the tests of the digital multimeter are to check the DC readings.

Software Diagnostics Routines

Many disk based diagnostic methods can check the system and identify the problems by running the number of tests on the different areas of the system hardware. These tests produce the visual reports and error messages to identify the nature of the problem. The most common software troubleshooting routines check the computer’s memory, keyboard, monitor, system processor, and hard disk’s speed. If the system CPU, hard disk and system clock is working properly, then you will be able to localize the problem by targeting the other points in the system. If the diagnostic tools/routines identify a number of defective software/hardware then you should replace one defective unit a time.

PC Hardware Troubleshooting Tools

Due to the low cost of the some of the hardware components, it’s usually not advisable to repair the IC level problems of the components, instead they should be replaced. The repair cost of the component will most likely be high as compared to the actual cost of the component. There are some very excellent hardware problem detection tools that are very helpful in identifying and isolating the problems. These tools included Multi meter, Cable Tester, POST card and software diagnostic disk.

Configuration Error Messages and Meanings

Press F1 to continue Invalid configuration
CMOS time and date not set CMOS battery error
CMOS memory size mismatches System configuration and setup failure
CMOS system option not set CMOS battery failure or CMOS checksum

After the beep tones occur during the startup process, the system now looks and loads the operating system. The errors that occur between the beeps and initializing the operating system can be categorized into the following categories.

• Hardware failure ( due to the physical problem with the booting drive)
• General Failure Error Reading Drive x
• Bad or Missing Command Interpreter
• Non system Disk or Disk Error
• Bad File Allocation Table
• Corrupted or missing operating system files
• Corrupted or missing boot files

The configuration or boot up problems can be occurred to the hardware or operational function’s failure and if the configuration is correct and these error appears this means there is some problems in the hardware and boot up problems are normally linked with the operating system.

PC Hardware Troubleshooting Techniques

Here you will learn about computer hardware troubleshooting techniques, cable testers, software diagnostic routines, POST cards, error diagnostic methods. Computer hardware is the physical part of a computer and it is frequently changed as compared to the software. Most computer hardware is inside the computer and cannot be seen by normal users. There are a large number of the computer hardware devices including Hard disk, CD-Rom, RAM, Motherboard, Monitor, printer, peripheral devices and other devices. One of the first steps in the troubleshooting is to sort out the hardware and software problems. You can use the event viewer utility in the Windows operating systems to identify the nature and cause of the hardware or software problem. Also you can identify the hardware problems by identifying the initial start up beeps.

Errors that occur before the initial beep shows that there is some kind of hardware problem exists in the system. At the POST stage, only the BIOS of the system and basic hardware is active and operating system does not starts to initialize at this stage until a final beep occurs. If a computer produces an error (“The system has detected Unstable RAM”) or a beep code appears, this means that system and found a problem with the devices and system RAM should be changed. Additionally, if the system starts up process reaches the point where CMOS configuration information is displayed on the screen this means that there is no problem detected with the basic hardware of the system. After this point, the system starts to load the device drivers and operating system.

You can categorize the system configurations errors and components failure errors. Sometimes configurations or setup problems occur when a new hardware is installed and used in the system for the first time. These problems occur due to the mismatches of the CMOS memory information and component's configuration information. It is usually advisable to access the system CMOS when the system is first time prepared, when it is necessary to replace the CMOS battery and when a new device such as hard disk, CD-Rom, RAM, Video adapter etc added to the system. In most of the computers, the BIOS use plug and play techniques to detect most of the devices. These components provide system resources to the newly added device. When you are installing a new devices or software, you may notice some configuration errors.

If you face the configuration errors, you should see the installation manual that comes with the new computer device. If you cannot confirm configuration problems and the device is not working properly, this means that there must be some defect in the hardware. The symptoms and errors can be divided into the three parts such as boot up problems, configurations problems and operational problems. First of all system’s configurations settings are checked. The error messages that occur during or after the end of the POST are reported so it is important to observe that where the problem is actually occurred.

Device Manager

If you're running Windows 95, 98, or ME, your first stop after the computer finishes the startup process should be the Device Manager, a piece of operating system software that helps you manage the various pieces of your PC. You can get to the Device Manager in several different ways: the two easiest are right-clicking on the My Computer icon on your desktop and selecting Properties from the context menu that pops up when you do this, or by going to the Start menu, going up to Settings, selecting Control Panel from the list of choices and then double-clicking on the System control panel. Either way, you’ll be presented with a tabbed dialog box; click on the tab that says Device Manager, and you’re there.

The first thing to look for is a yellow exclamation point or red international no sign (you know, the circle with the slash through it) next to one of your devices. You may need to click on all the little plus signs next to each category of devices to see the full outline-like list of everything in your computer. If you see the yellow or red symbol, you know something is amiss. My first suggestion is to highlight the offending device and click on the Remove button. What this does is essentially erase the driver software associated with the device as well as references to it within the Windows 95/98/ME Registry. (The Registry tracks all the hardware and software you install, the preferences you set for each, as well as lots of other stuff). The fancy term for this is "logically" removing the device because, even though it may still be physically attached, the computer no longer has any record of its presence.

Next, you should restart your computer, let Windows' Plug-and-Play feature "find" the device again, and redo the driver installation process by either using the driver suggestions that Windows finds and makes or clicking on the Have Disk button and using the installer disks that came with the device. (If both options are possible, I’d go with the disks that came with the hardware—unless you’re sure they are an older version.) If the computer doesn’t find the device, then I would suspect the connections or the device itself. Buy another cable, unplug and re-plug the connectors, remove and then physically reinstall any new plug-in cards or do whatever you have to to ensure that the connection is solid. Once you’ve done that, you’ll find that many times, simply reinstalling the drivers solves the problem.

PC Hardware Troubleshooting Tips

Though they tend to cause some of the nastiest symptoms—computers that won't boot, scary and/or confusing error messages, etc.—computer hardware problems are usually the easiest type of problems to solve. The trick, as with all troubleshooting ventures, is to figure out where to start and then focus your efforts.

First, of course, you need to check the stupid stuff. You'd probably be amazed how many "problems" are solved by connecting the cables, or turning on the power switch that you swear you just did. Beyond that, double-check the snugness of your connections—jiggling in a new add-in card or screwing in a cable connection can (and often does) make a difference. You may even want to check the integrity of your cables and connectors. I once solved a baffling SCSI problem by noticing that one of the pins in a miniature 50-pin SCSI-II connector was bent. I had mistakenly presumed, prior to that, that a bent pin would have prevented me from making a connection at all, but it didn't. Unfortunately, as a result, I wasted several hours on something that could've taken two minutes.

Finally, whenever you install something new, whether it's more memory, a new drive, a plug-in card or what-have-you, and something doesn't work, it's more than likely because you made a mistake somewhere in the installation process. Step back through the process again, double- and triple-check your connections, and then try one more time. In the case of RAM that doesn't work or isn't recognized, it could be an incompatibility with the specific manufacturer of the RAM and your motherboard, so see if you can try a different brand before you give up hope. Finally, in some instances installing something new causes a conflict with something else--which is what the rest of this article is all about.

Hard Drive Failure Troubleshooting


Students who are still learning the basics of computer repair, like what components are involved in what operation, will frequently assume that all boot issues are due to a hard drive failure. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. I don't mean that hard drives last longer than memory modules or video cards in the pure MTBF (Mean Time Between Failure) sense, I mean they are rarely at fault when you're called in to repair a PC. Hard drive failures are generally pretty easy to troubleshoot, in part because the operating system will include tools to report on the hard drive's reliability when it's accessible.

Motherboard and CPU Troubleshooting


There are very few instances when you'd turn on a PC, have it either power up or not, and be able to say, "Oh, that's a motherboard problem." Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." If you want to learn how to repair PC's without swapping every part, it's critical to know what to look for on a powered up system, like a CPU fan that isn't running, or RAM that stays cold. Sometimes you can spot a blown capacitor on a motherboard, but it's not a common problem.

Comparing Registries

While working with changes to your system, you might want to see what is changing in your Registry.
Since you can export it to a text file, the steps are fairly easy

Start Regedit
With the very top level select - My Computer, on the Toolbar select Registry / Export Registry File
I usually save it to the root of the C: drive with the name before (you don't need to add an extension)
Make the change to your system
Go back to Regedit
Press F5 to update it
Export the Registry like step 2
Name the file after and have it go in the same directory
Open up a DOS window
Go to the directory where the two exported files are
Enter FC before.reg after.reg > diff.txt
Then you can edit diff.txt with your favorite text editor.
Note: I do the last steps so often I have a simple batch file already set up.

Preparing to Move Hard Drive to Another Computer

To remove the devices from device manager when taking a HD from one computer to another,
simply:

Run Regedit
Go to HKEY_LOCAL_MACHINE\ and delete the Enum section
This removes all of the hardware specific settings

Setting the Internet Explorer Home Page

If you want to set the home page used by Internet Explorer through the registry

Start Regedit
Go to HKey_Current_User \ Software \ Microsoft \ Internet Explorer \ Main
Give the Start Page key the string value you wish set as homepage

Setting the Recycle Bin to Always Delete

You can set the recycle bin to always delete items (like holding down the shift key when dragging files to the recycle bin)

Start Regedit
Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ BitBucket
Set the key NukeOnDelete to 1

Changing the Location Of Special Folders

You can modify the registry to change the location of special folders like:

My Documents
Favorites
My Pictures
Personal
Start Regedit
Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
Double click on any locations you want to change and alter the path
Logoff or restart for the changes to go into effect
Note: TweakUI from Microsoft will allow you to make these changes from a dialog box as well

Turning off System Beeps

If you want to turn off all system beeps (like the ones that go through your computers' internal speaker):

Start Regedit
Go to HKEY_CURRENT_USER\Control Panel\Sound
Edit the key Beep and give it a value of No

Locking File Associations

If you have your file associations the way you want for a particular file type, you can remove it from the list that gets displayed in the Folder Options / File Types screen

Start Regedit
Go to HKEY_CLASSES_ROOT
Scroll to the file association you want to lock.
In the right panel, create a new Binary value
Call it EditFlags
Give it a value of 01 00 00 00
Now when you go to the Folder Options / File Types screen, you won't see that file type listed.

Preventing Changes to File Associations

You can prevent users from changing associations via Windows Explorer's Tools / Folder Options / File Types tab.

Start Regedit
Go to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explore
Create REG_DWORD data type NoFileAssociate
Give it a value of 1

Disabling the F3 Search Key

If you want to disable the ability to use the F3 key from either the Windows Explorer or Internet Explorer

Start Regedit
Go to HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Restrictions
Create a Dword value called NoFindFiles
Give it a value of 1
Reboot

Allowing Network Access with Blank Passwords (XP and Vista)

Although you can log in locally without a password, by default, WindowsXP Pro does not allow network users to access the computer without a password. Typically you will receive an Unknown error 31 if this is the case.

To change this setting:

Run gpedit.msc
Go to Computer Configuration / Windows Settings / Security Settings / Local Policies / Security Options
Double click on Accounts: Limit local account use of blank passwords to console login only
Disable this option

Kill Hung Processes When Logging Off in Windows NT

When you tell NT to shut down, it first sends shutdown requests to any running processes.
Most 32-bit applications honor these requests and shut down, but older 16-bit apps running in the Virtual DOS Machine often won't.
When this occurs, the operating system prompts you with a dialog box asking if you want to kill the task, wait for the task to die on its own, or cancel the shutdown.
By modifying the Registry, you can automate this process.

You can force NT to kill all running processes on shutdown by adding a REG_SZ value named HKEY_USER\\ControlPanel\Desktop\AutoEndTasks and set the value to 1. You can also add this value to HKEY_USERS\.DEFAULT so that all new accounts will shut down the same way.

An Overview of Web Development

Web development has consistently proved itself to be a lucrative business option and perhaps it is one of the fastest growing industries in the world today since its dawn in the late 90s in the US and Europe. The growth of web development is majorly pushed by medium and small business firms, and even the big names are also somewhat intimately related to web development. The potential of the internet to reach global audiences makes it almost indispensable for any company, whether small or large to make an online presence. From this point of view, web development is significant as it is the process of developing any website to convey essential information regarding the products or services that any company has to offer just about instantly to the customers anywhere in the world. To automate the business workflow and to create a brand value for the internet users, web development seems to be obligatory these days.

Web development is a rapidly growing industry owing to the fact that most of the business entities are aware of the great advantages of the internet technologies and have therefore felt the urge for making their online presence for reaching customers all over the world. Web development is both an art as well as science and it includes all the aspects of developing a website on the internet. More precisely, a web development company simultaneously takes care of web design, programming using different languages, server administration, managing of content, marketing and finally testing and release. The progress of any business solely depends on the number of prospective customers and an online presence together with quality content and valuable information increases the chances of conversion of visitors into customers manifold. Amazingly enough, one time investment on web development can serve the purposes for years to come.

A well developed web site must essentially comprise of some user-friendly features like remote login, taking orders, viewing reports, options for online transactions, knowledge and opinions sharing etc. To get the best out of a web development company, the task of web development should be left over to professionals, but to find out the right one is even more difficult at the first place. Planning is the most important part of successful web development. A business must identify the purpose and intention of the website aimed at. A web development company should first determine the target audience of the website they might be developing. The planning also includes designing the website to make it attractive as well as user friendly, determining the programming languages that are compatible for using and maintaining. Content is a very important part of any website and should therefore be arranged according to hierarchy of logical sections. Clarity of information is another important aspect of web development. With clear and precise information web developers can be able to produce code out of virtually anything that one desire to develop

Laptop battery stop discharging, why

Maybe we all face this situation : Some times we should travel to some place as the business or holiday. You know the 12 hours or more journey time is too wearily. So we like enjoy ourself with our laptop to watch movie or play game. Suddenlly the Dell Latitude D620 Battery stop dischargging in the 70% power state or more. You maybe very confuse about this : maybe some problem with my laptop or my laptop dead. In fact most of them are caused by the temperature or the over-Current.

Most laptop batteries have the protection circuit. When the laptop battery temperature is too high or discharge current is too large, out of laptop battery protection circuit action standards. Thus causing the Dell Latitude D600 Battery power automatically stop discharging and force the issue.

The most common situation is that laptop battery is running at full speed . The Dell Inspiron 710m Battery current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery. D0 not panic in that case. You only used to disconnect peripherals and wait about 10 minutes, then you can reboot the machine.

There is also a common situation : using the battery in a hot environment and high-load operation, , so that the ambient temperature plus the heat generated by the battery self-discharge Dell Inspiron 640m Battery protection circuit may exceed the preset temperature, which is particularly high frequency P4 machines in high-temperature environment may occur after high-speed operation.

Encountered such a situation should remove the batteries placed in a cooler place (remember not to put refrigerator frozen!), After half an hour should be back to normal. High temperature for the lithium Dell TC030 Dell PC764 battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment and high-load operation.

Change the battery cell is not a good choice

When we want to repair our laptop battery, we often see some laptop battery maintenance introduce the change battery cell service. You just spend 30$ or less to repair original laptop battery by change the battery cell. As buy a new original laptop battery may cost you 200 $ or more. It looks great but it is really worth?

It has some risk when changing the original Dell laptop battery cell. The batteries can be changed, it is very simple because the battery inside is just some series and parallel battery packs. But the corresponding protection board can not be replaced.Most of the protection boards are added secret infomation the time in the factory , only can be debugged in Dell laptop battery production plant.

Battery Protection Board are based on the corresponding matching HP HSTNN-LB31 battery packs to debug a good, if the random replacement of batteries while protecting the panel without doing the appropriate debugging shield of protection features may fail, so the risk is relatively large.

Another point, if a single change batteries, then is a bad, because the internal resistance of the old and new HP PM579A batteries do not like the efficiency of the battery pack will drop a lot, but for the life of the new batteries also have a significant impact, and we manufacturers to replace the batteries are replaced all the batteries.

Generally laptop battery life is 1-2 years, so the Compaq EVO N400c Battery in the warranty period, warranty or replacement directly to vendors, it is better to buy a new battery replacement when out of the warranty period. After all, the cell-change battery may damage your expensive laptop.
