Tips for Laptop Screen Repair

Three Tips for Laptop Screen Repair :

1.  Do not take your laptop to a PC repair in Surrey for laptop screen replacement
when you notice a flickering image on the laptop. In many cases it is not the screen
that is causing the problem. The problem may lie with the inverter which supplies
power. Replacing the inverter will do the trick.

2.  If the screen is lit, but displays only white colour then the problem must be in
the connection between the system board and display. Tighten it if it is loose and
replace it if is damaged.

3. The laptop computer repair people also told me that in quite many cases where
people complain of a faint display on their laptops, they have either accidentally
lowered the brightness from under the power option in the control panel of the
operating system, or the backlight of the screen is not properly adjusted.

WHAT ARE THE TIPS TO REMEMBER WHEN BUYING A PERSONAL COMPUTER ?



TIPS TO REMEMBER WHEN BUYING A PERSONAL COMPUTER : 


1) Know what you want BEFORE you go looking or buying. Many people get convinced they need a more expensive or "powerful" computer, when in fact they do not. People who do word processing for a living do not need a Pentiumbased computer necessarily; an 80486DX-based PC will do just fine when buying new, and in fact an 80386-based PC will really do just as well. DECIDE WHAT YOU WANT THE COMPUTER FOR BEFORE YOU BUY IT! Let your software choices and intended uses of the PC drive your purchasing choices, not what some salesman says. If necessary, bring a knowledgeable person along who can help to sort out the truth from the noise.

2) Comparison shop the area stores: DON'T buy on impulse. Write down what you want to buy, be as specific as you can. Compare the prices of several dealers in the paper; call the companies if necessary and have them give you a price quote. Many will even fax you a price quote. If you like a system and it's $40 more than a competitor's price, see if they will match the price - many will do this. Take at least 2 weeks to go through this process.

3) Get ALL promises for service & support IN WRITING before buying the PC. Verbal agreements between you and the salesman are never binding in a court of law, if things should get to that point. Therefore, get any warranties, service agreements, and support agreements IN WRITING before you buy your PC. Speak to a supervisor or manager if necessary, but don't accept any verbal agreements as binding commitments.

4) Test the computer before it leaves the store or house. Nothing is more frustrating to the new computer owner than to find that the 150Mhz Pentium system will only run at 90 Mhz, or that your 3.5" floppy drive doesn't work, or that your monitor has squiggly lines all over it when you leave it on for more than 10 minutes. The store should have already tested the computer before you pick it up, but this isn't always the case. It only takes 5-10 minutes to assemble the system and test everything; insist on doing this. Use a diagnostic program like Checkit or Norton Utilities to evaluate the operation of your computer. If something's not right, insist that they fix it BEFORE it leaves the store. Use the same rules when buying a used computer from someone's home: run diagnostic software on it BEFORE you fork over the cash.

5) Insist on getting some menu software installed on your PC, and have someone properly configure your application software BEFORE you venture into the PC world. The main reason new PC owners get so frustrated is that they have no easy way to get in and out of their new programs. MS-DOS is not an easy operating system for the novice to use. Therefore, make sure that you get some kind of menu software (Automenu, Direct Access, Windows, etc.) installed and properly set up on your PC before you start using all of your new software. Have the store or some well-trained PC maintenance person set up the programs on your hard disk as well as the menu program you choose. By doing this, you will be able to use your programs immediately, without having to struggle with DOS.

6) Never buy from the guy in New Jersey - ALWAYS BUY FROM LOCAL, REPUTABLE SOURCES. The guy in New Jersey is probably a reputable dealer, and probably sells quality parts. BUT, if your part breaks during the warranty period, where do YOU have to go (or mail the part) to get a replacement. Always buy from local retailers that are reputable, that sell name-brand equipment, that give warranties, and that have a good name in the local industry.

How to remove Virus from USB Drives

Remove Virus from USB

One of the ways by which a virus can infect your PC is through USB/Pen drives. Common viruses
such as ’Ravmon’ , ‘New Folder.exe’, ‘Orkut is banned’ etc are spreading through USB drives. Most
anti virus programs are unable to detect them and even if they do, in most cases they are unable to
delete the file, only quarantine it. Here are the things which you can do if you want to remove such
viruses from your USB drives.



  •  Whenever you plug a USB drive in your system, a window will appear similar to the one shown
  •  Don’t click on Ok , just choose ‘Cancel’.
  •  Open the Command Prompt by typing ‘cmd‘ in the run box.
  •   In the command prompt type the drive letter: and press enter. 
  •  Now type dir /w/a and press enter.

  •  This will display a list of the files in the pen drive. Check whether the following files are there or not:
                • Autorun.inf
                • Ravmon.exe
                • New Folder.exe
                • svchost.exe
                • Heap41a
                • or any other exe file which may be suspicious.
 
  •  If any of the above files are there, then probably the USB drive is infected.
  •  In command prompt type attrib -r -a -s -h *.* and press enter.
  •  This will remove the Read Only, Archive, System and hidden file attribute from all the files. 
  •    Now just delete the files using the command del filename.

KEYBOARD TESTING



KEYBOARD TESTING GUIDELINES

Locate a keyboard; notice the appearance of the keyboard.




 KEYBOARD TESTING


1.     There are 2 kinds of keyboards:

o   XT keyboards.
o   AT keyboards.

         XT keyboards are usually 83-key keyboards.

        AT keyboards are usually 101-key keyboards.

        Some keyboards have an XT/AT mode switch on the bottom.

2.     Plug the keyboard into the appropriate test PC and turn on both the monitor and PC.

3.     Use some kind of software to test the keyboard's operation (Checkit, XT or AT diagnostics, etc.)

4.     If the keyboard works properly (that means ALL the keys work), label the keyboard and store it in the appropriate place in the lab.

5.     If the keyboard does not work correctly, test and make sure that the keyboard is attached to the correct PC.

6.     If the keyboard is REALLY DEAD, indicate this on the dead keyboard log and dispose of the keyboard.

7.     If you need assistance, let someone know. If you're unsure of whether a keyboard is OK or not, label the keyboard as such and move on.

HOW DO VIRUSES AFFECT YOUR PC ?

HOW DO VIRUSES AFFECT YOUR PC

Viruses will affect your PC in 4 different ways . . .

•    The Boot Sector
•    The File Allocation Table
•    The Partition Table
•    .COM and .EXE Files


The Boot Sector:

The boot sector is where your operating system files reside on your floppy or hard disk. A virus will go to that location on your disk and corrupt these files (IO.SYS, MSDOS.SYS, and COMMAND.COM) so that your PC will NOT boot up as expected.


The File Allocation Table:

The File Allocation Table (FAT) is a list of all the files on your floppy or hard disk, and where the files are physically located on the disk. A virus will corrupt the FAT so that you cannot locate or access your files.


The Partition Table:

The partition table on your HARD DISK tells MS-DOS how big your hard disk is, and what percentage of it is used by MS-DOS. A virus can corrupt your partition table, which wipes out ALL of your files in an instant.


.COM and .EXE Files:

 Files with these extensions are EXECUTABLE files, which perform a specific action. A virus can attach itself to one of these kinds of files and corrupt the way it operates.

HOW to install your new Ram



To install your new Ram, perform the following :

Check to see if you have ample light. You may want to have a container to place small screws in. The system unit cover may have small screws and you don't want to lose them.
After you have plenty of work space and ample lighting, prepare your mind as well. Make this and every other adventure of working on your computer educational and fun.

Take the time to study the actual components inside your computer. You'll be glad you did should something go wrong. Follow these steps to install your drive.

First  : Turn off your computer and unplug all peripherals. Take notice of how you unplug or disconnect any devices. Locate the RAM on the motherboard.

Second : Remove the side panel of the tower system or the cover if you have a desktop. Place the panel in a safe place well out of the way.

Third : Before touching anything inside the system unit, remove electrical static charge from your body by touching a door knob or any unpainted metal surface.

Fourth : Remove the new memory from its protective wrapping and locate the sockets or memory banks to install the new memory chips.

Fifth : Notice the type of retaining clips that hold the chips in place. Remove any old chips you intend to move.  Now to be sure you won't damage the chips, ground yourself again to remove any remaining static electricity.

Sixth : Pull the retaining clip open and carefully slide the RAM Chips in their memory banks. Push the clips back over the new memory chips.

Seventh : Check and double check the firmness of the chips by gently trying to move the from side to side. Take a good long look at the chips for anything that looks unusual.

Eighth : Replace the system unit cover and reconnect all peripherals. Reboot the computer and the operating system should recognize your new or added memory without any problem. Its that easy when it comes to installing new or more memory. 

Read your computer's manual first to find out what type of ram memory you have and what is needed for upgrades. Take time to Visit the Kingston Memory site above and use their memory configurator to find out the memory you need to upgrade your computer.
And go ahead and enjoy the faster speed you should experience once your new memory is installed. Don't forget to run scandisk, defragment and disk cleanup to clean your hard drive of extra space.
