Static electricity can Kill your PC

Static electricity are very harmful to some electronic devices such as Computers and Laptops. One time a friend was bending over me watching me while i was fixing a computer and i didn't notice he was not wearing any foot ware. When i tried to lean back my ears accedentally touched the his eyelids that we both screamed in pain cos of that spark that lit up. This is what they call Electrostatic Discharge or ESD.

When ever you wanted to fix your computer of laptop be sure to wear a rubber shoe or sandals  and if you don't have any anti-static wrist straps to wear on while fixing, try to hold on the chases of your CPU for a 20 sec. to discharge yourself before touching any delicate parts of your PC.

Noisy Cpu?

You'll wonder why your CPU is giving a loud buzzing or humming sound.  Most likely those fan are getting too much dust in it and if you don't fix it, they will burn out and may damage your system.
All you need is the CPU power off, open the side panel and take that noisy fan out. Dust off those fan blades. Slowly peel off that label located on one side of the fan. some of this fan have a rubber like plug on top of it which is very easy to pull out.
If you have this kind of oil use for sewing machine that will be just fine.  Just one drop will do. Wait for the oil to sip in. and try to gently spin those fan blades until you will notice that fan will slowly spin smoothly. Put the plug back and stick that label back on top of it. Put it back to its original position, close that side panel and turn your CPU on.    Noise is gone!!!

CRT vs LCD

The primary advantage that CRT monitors held over LCDs was their color rendering. The contrast ratios and depths of colors displayed were much greater with CRT monitors than LCDs. While this still holds true in most cases, many strides have been made in LCDs such that this difference is not as great as it once was. Many graphic designers still use the very expensive large CRT monitors in their work because of the color advantages. Of course, this color ability does degrade over time as the phosphors in the tube break down.
The other advantage that CRT monitors held over LCD screens is the ability to easily scale to various resolutions. This is referred to as multisync by the industry. By adjusting the electron beam in the tube, the screen can easily be adjusted downward to lower resolutions while keeping the picture clarity intact.
While these two items may play an important role for CRT monitors, there are disadvantages as well. The biggest of these are the size and weight of the tubes. An equivalent sized LCD monitor is upwards of 80% smaller in size and weight compared to a CRT tube. The larger the screen, the bigger the size difference. The other major drawback deals with the power consumption. The energy needed for the electron beam means that the monitors consumer and generate a lot more heat than the LCD monitors.

Do's and Don'ts on Laptops

You might find this article a little funny to read, especially since many laptop do’s and don’ts only require common sense. But you’ll be surprised by some of the things laptop owners do to their poor laptop units that lead to heightened wear and tear, and shortened laptop life. I had a colleague who fell asleep on top of his laptop and woke up to a black screen that would never work again. It would boot, he could hear it, but nothing would appear on the screen. This is just one example of simple laptop use rules – don’t fall asleep on your laptop.

When you own your very own laptop, it is vital that you keep it in tip-top condition so that you can get the most out of the unit and experience a long, healthy and productive relationship with it. Always make sure that your laptop is stored in a dry and cool area, and never store it in direct sunlight. Make sure that your laptop is always in a stable and secure place where if jolted in any way, it will not easily fall and break.
When using your portable laptop, do not use it next to any other piece of equipment that emits heat. Therefore, do not place it too close to another laptop unit whose fan is running and releasing hot air from within the unit to keep it cool. When laptops are connected to a DLP or LCD projector, be sure that your laptop is not directly facing the fan system of the DLP unit. DLP units tend to heat up quickly due to the high lumens that the projector lights contain to project images, which is why their fans release a hot air when the unit it in use. Keep your laptop away from this hot air if you want it to keep working in top order. Never use your laptop when you are drinking a beverage or are eating food. Any food or beverage that gets in contain with your laptop may just destroy vital functional parts of it.
When using a wifi signal that is external to your usual one, be sure first that your laptop’s antivirus software is updated and functioning. Also make sure that your laptop’s firewall is in its correct security settings to prevent any kind of threat from getting into your computer system. Defragment your files and make a disk-check regularly on your laptop. Be sure that your antivirus updates itself automatically and does regular and schedule virus scans of your system.
For a little extra security, do not share any folders on your laptop and disable the service called printer and file sharing option on your computer just to make sure. When you surf the internet, don’t open suspicious emails from sources you do not know. This will prevent viruses from getting into your computer. Overall, by following the advice of the laptop manual and from the service centers that you bring your laptop to, you can be assured to expect the your unit to last the lifetime that your laptop company guaranteed you on the day that you purchased it.
