My laptop turns on, but I see no video?
This issue can be pinpointed to two separate items very quickly.
If your laptop will display a video on an external monitor, then you have a hardware issue with either your inverter or your backlight.
You can change the CCFL, which is referred to as the backlight, by disassembling your LCD screen and clipping the AC contact wires that are white and pink. New CCFL bulbs have to be soldered in after clipping. I get asked if inline butt splices will be crimped in and applied instead of soldering. With each system having different clearances, I see that as highly unlikely.
To change an inverter bar, you simply match model numbers and unplug a molex connector.
If it will not display externally, then your issue is geared more towards a BGA onboard issue. HP DV2000, DV6000, DV9000, TX1000, Dell D620, D630, D630, D820, D830 systems with Nvidia chipsets have the known BGA issues that I can fix.
Most systems need a double or triple chipset reflow.

Inside your average laptop there are many chemicals such as polyvinyl chloride plastic (PVC), brominated flame retardants (BFRs) and lead. Exposure to these chemicals can cause many health issues such as reproductive problems, central nervous system damage, cancer and many other ailments and sicknesses. When you throw your electronic devices in the garbage they end up in a landfill which is the perfect environment for these chemicals to leak into the ground and get into the water you drink.
The environment also takes a hit when it is exposed to these chemicals. They can kill plants, animals and ruin a beautiful ecosystem that relies on each part to function properly.
Where to recycle properly
In the US and Canada there are many local companies, programs and centres that will take your broken/old/unwanted electronics for free and some may even give you money for your electronics if they are newer models. These companies are very prominent these days so a quick look in your yellow pages and you should be able to find somewhere to recycle them properly.
Many provinces and states have government programs that offer these services and there may be a drop off location closer than you think.
Beyond recycling
Don’t get me wrong, recycling is important, but wouldn’t it be more environmentally friendly and save energy if we were to reuse and/or reduce our electronics? Most definitely.
If you find yourself needing a new phone or laptop maybe think about buying a used one from your local classifieds or other used electronics dealers online or offline. You can usually find devices that are in new condition and work great but are cheaper because the package has been opened. Some of these devices may even still have warranties or a warranty may even be provided by the dealer.
On the other hand if you’re trying to get rid of your old phone or laptop think about reselling it, giving it to a friend or family member or donating it to a charity that will put it to good use. As mentioned before there are also many companies that will give you money for your electronics. These actions will keep your device in use and save the energy it would have taken to recycle it. Plus it will give someone the opportunity to buy a cheaper used device instead of a new one.
Doing these small things can have more of an impact than you think. If you follow these guidelines you will be sure to make a difference on the environment and feel good about it at the same time.

Computer issues can be tricky. Sometimes they can just happen without any warning. Issues may arise due to a power surge, a hardware failure, a virus, etc. We strongly believe that anyone should have a backup system in place. Either you opt to subscribe to an online backup system, or you just buy an external hard drive and set it up, one should always have a backup. Computers being cheaper, you can most of the times buy a new computer, instead of spending hundreds and hundreds of dollars on a computer repair service. Sometimes a computer hardware failure can take place and the computer can still run. This is one of those tricky situations, just because computer can crush at any given time. When this happens it is still very important to fix the issue promptly. Ask a savvy friend or just visit a computer repair shop. Nowadays, many computer service center offer free diagnosis.
In other cases, a hardware failure is so obvious, that there is no doubt you need to visit a computer shop (lines all over screen, computer doesn’t turn on, hard drive makes strange noises, etc). A virus is also something you should be aware of. We advice everyone should have an antivirus system in place. Yes, ONE! Not two or three or more! One antivirus is enough! Some viruses are more than obvious, popping up on your screen anytime you try to do something. These viruses are very annoying, but at least we know that the computer is infected and actions needs to be takes as soon as possible. Most of the computer shops can fix this problem.
In some other cases, a slow notebook or PC is one sign that you may need to have your computer checked for viruses. It may be also if you see a blue screen and have to reboot several times when running certain software.
For anyone that’s not sure about how much something may cost when it comes to a PC problem — it’s easy to get an estimate. This way you know what it’s going to cost you and when to expect repairs to be done. Something that may be very important when you are running your own business or simply rely on your PC on a day to day basis.
Computer repair shops are valuable to all of us as technology continues to consume our lives. It is important that you look into finding a reliable computer repair shop in your area that is reasonable, fair and able to explain to you what is happening with your PC. If they are of little help check the web. Don’t be fooled by sites that are littered with technical jargon and tons of corporate testimonials. When looking for PC repair you need a middle ground. Someone who is professional, technical and that can relate to any computer user. Make sure you are happy with the service you have received and the explanations that have been given. This way you stay in control of the service and can make sure that the computer has been repaired and you understand what was done. Once you find a reliable computer shop, you will always these people for any computer related issues.

Reverse Image: Lincoln Memorial in Washington, D.C.
Metal Composition: 97.5% zinc, 2.5% copper
Total Weight: 2.5 grams
Comments: The zinc and copper versions of the cent were both produced in 1982. They can be differentiated by weight (3.11 grams for the 1909-1982 copper cent, 2.5 grams for the 1982-2011 zinc cent).
Now, I had written a few forum posts on the HP Support forums stating about the copper shim danger and what it can do to your chipsets when a guy from Ontario made the comment.
Well, I agree copper shims are bad. I used a penny in a repair and it failed, that is why now I use dimes because they are made of silver.
Well, let us put the facts straight. Dimes may appear silver, but have not been made of silver since 1964. Not one grain of silver is in what is called a clad coin, or coins produced after 1964 for general circulation unless it is a Kennedy Half Dollar or Eisenhower Silver Dollar up to 1971 which are 40% silver by volume. Below is the chart showing us what is in a dime.
1965 – 2011 Roosevelt Dime Value (United States)
U.S. MINT SPECIFICATIONS
Denomination: $0.10
Obverse Image: Franklin D. Roosevelt, 32nd President of the United States.
Reverse Image: Torch, oak branch, and olive branch.
Metal Composition: 91.67% copper, 8.33% nickel
Total Weight: 2.268 grams
Comments: The term ‘dime’ comes from the French word disme, meaning “tithe” or “tenth part.”
We also see how pennies are made of zinc, not copper, as the primary composition which rates nowhere on the chart. That can be found here:
Zinc 116
The idea of using pennies as copper shims will not work. Then using a dime will? No, the idea of running dimes as copper shims will work in theory except the principal of thermal conductivity says the dime will heat up to transfer the heat from the shim, but goes nowhere after that. Heating the motherboard in such a localized manner can cause the flexing, or distortion, of the PCB layers. With distortion, you get flexing and uneven heating causing unrepairable damage to the layers of the motherboard.
As a trend I see variations of the heater coil principal were homemade heat sinks are comprised of aluminum and copper layers. The idea is that the application of the principal in industrial applications can be scaled down to work properly in a electronic situation to help or assist the removal of heat. I give an A for effort, an A for logic, and a F for practicality. As technicians we have to reference back to the principal of thermodynamics and its first law then place logic that convection is the mode of transport for this energy that we are trying to displace. When we take all of that into account we find that the logic and effort will not move the mountain of practicality. Below is an example of an aluminum handmade heatsink placed on a laptop chipset by an eBay seller:
Between the 27 single layers of aluminum foil we see and the electrical tape we have to wonder if this was actually worth the effort. Doubleclickittofixit HP Repair, Doubleclickittofixit HP Repair, Doubleclickittofixit HP Repair
This section will try to answer the most often asked questions I get.
Follow the links below for an indepth answer to each question.
My desktop turns on. I see no video?
I run into this more and more these days. Generally, you have two issues. First being your video cable. You can check that simply by seeing if it is connected, and if so connecting it to another system.
If your monitor works fine, then your next issue is the video chipset. More and more I find the newer HP, Dell, and Acer desktop systems use the same Nvidia chipsets as the laptop systems for the HP DV and TX series.
I also find that the add-on video cards, both ATI and Nvidia, have poor circulation fans if any at all, and the chipsets on those need to be reflowed also.
I also find the system may have a capacitor issue. It would display the same signs as a reflow.
To check, just take your cover off, and look at the capacitors. If they are bulging, leaking, or domed, you have a capacitor issue.
Systems that have this issue on a regular basis are Dell SX, GX, OptiPlex, and Dimension systems. I am seeing newer OptiPlex 740, which are AMD based systems, and OptiPlex 745, which are Intel based systems, with capacitor issues.
