Dangers of CHEAP Laptop Chargers

The Dangers of buying Cheap Chargers

There are many chargers on the market, but its not always good to go for the cheapest one you find. Many of the cheap chargers are of a very poor quality with no shielding and only last few Months and can damage your laptop.  Normally the Cheap chargers are very light and feel hollow.

Charger types If you lose power on your laptop that means that your laptop charger could be faulty or incompatible with your laptop or the power socket is broken or loose. Although there are many different laptop makes and models they all use similar chargers using different variations of connectors. It is very important to use the correct charger for your laptop to prevent physical damage, battery problems or even more serious faults.

 

 

A few basic rules to follow when selecting a charger for your laptop.The most important thing to remember is that you need to match the output voltage that your laptop requires. This is written at the bottom label of the laptop itself. If it requires 15V any charger that outputs 15V or even 16V will work fine.For 19V any charger that is 19V or 20V will work fine. so the chargers output Voltage must equal or be slightly higher than the recommended voltage for the laptop.Charger types

 

The next parameter of the charger is the current it can provide. For example if your laptop requires 3.14A anything more than 2A will charge the battery fine. The current defines how quickly the charger can charge the battery. For example a 5A charger will charge a battery in 2 hours where a 3.14A will need 3 hours to complete the charge.

 

One more thing to remember is that the current required by your laptop should not be more than 2A than your charger can output. for example if your laptop requires 6A you shouldn’t use a charger that is less than 4A.

Simple safety checks for laptop power supplies

 

Don’t get caught out with poor quality laptop power supply units. This video shows you some very simple checks to make sure that the product is not dangerous. Please note that these is basic checks and in no way confirms that the product is 100% safe.

Dust, heat are a computer’s worst enemy

One of the worst things that can happen to a computer is for it to overheat because usually it will cause the power supply to fail and possibly damage the motherboard.

To keep this from happening make sure there’s good air flow through the computer. All exhaust fans must be working properly and air intake vents can’t be clogged with dust if there is going to be good air flow.

Computer Killer … Dust !!

 

Usually there are at least two fans that keep the processor cool. The processor exhaust fan sucks air from the intake vents and pulls the air across the disk drive and electrical components, thus removing the heat generated by these components. The second fan is on the power supply. This fan performs a similar function by drawing the air through the power supply and exhausting the hot air out the rear or side of the processor. Failure of either of these two fans can cause major trouble, and ultimately computer failure.

Fan failures can occur, but aren’t very common. The biggest problem to overheating is dust. In our area, we really get lot of dust. When the air intake vents clogged, sufficient air cannot be pulled through the computer to cool the components.

Leaving the computer set on the floor or worst yet, set on carpeting, contributes to the dust, pet hair, and carpet fibers that are sucked into the air intake and clog the ventilation holes. If you’re a heavy smoker, the problem is actually compounded from smoke particles that often mat the dust and hair completely blocking the air flow.

The computer needs to be periodically cleaned out to remove the dust wads, clumped pet hair and carpet fibers, as well as bugs that often crawl inside the computer (crickets are very common). Fan blades often collect large amounts of dust particles. Dust collecting on fan blades makes the fan blades out of balance causing excessive wear on the bearings.

The air intake on the power supply is a big area of concern. Dust and fibers that get into your computer will generally end up stuck on the air intake grill of the power supply. When the air intake to the power supply is restricted, the power supply can overheat and burn out. This can also cause damage to the motherboard.

Another critical area to clean is the vents in the heat sink on the processor. Most late model processors that have high speed processors generate a large amount of heat. Most hardware manufactures install a heat sink on the processor to help dissipate the heat. When the fins on the heat sink clog with dust, the heat cannot be properly dissipated and the processor can overheat.

Extreme care needs to be taken when removing dust and debris from inside the computer. The proper cleaning equipment needs to be used so that components on the motherboard are not damaged. The normal household vacuum (or shop vac) can suck components right off the motherboard.

Cleaning the inside of the computer is a long tedious process and can take several hours if done properly. This is definitely a job that should be left to your computer professionals. Cleaning out the dust from your computer should be done at least annually, and if your computer sets on a carpeted floor, every six months is recommended.

‘Look Up’ is a Video EVERYONE Needs To See

For The First Time In My Life, I’m Speechless.

“This media we call social is anything but, when we open our computers and it’s our doors we shut”… This is one of the most vital messages that everyone needs to hear.

Look Up is a spoken word for the “online” generation. Written, performed and directed by Gary Turk, it is an extremely important life lesson for our youth.  Children are growing up in a world where they don’t play outside or communicate with their friends. It seems today everything is done via text message or over the internet. It’s heartbreaking… I feel guilty myself. We need to spread this message before it’s too late. Please do your part and SHARE it with everyone you know.
