The machine keeps breaking the thread, how do I fix it

Thread breaks are caused by one of quite a number of reasons on any machine. It could be that there is a burr on the needle plate or along the thread path that is fraying the thread or the needle might be damaged or not seated properly. Another common reason is that the cone of thread has aged and rotted or the thread is simply not traveling in the proper path. And one issue that causes thread breaks, most especially in winter months or in naturally dry environments is a lack of humidity. Use a humidity gauge to determine the humidity around the machine and when the gauge drops below 25, run a humidifier to maintain the humidity up to an average of 30-40 percent.

mother board heats up and computer does not start

Does it start up at all ? Will it start up in Safe mode ?

Heat will cause computer components to expand sometimes not being able to make connecting to the hard drive. Could be a problem with the Hard Drive or the Hard drives PCB http://www.onepcbsolution.com/ Motherboards can go bad for many reasons, although there are a few common culprits. Among the most common causes of motherboard failure are excess electrical shocks, physical damage, or excess heat. Some of these dangers are inescapable, and may vary in likelihood depending on your computer model. Fortunately, there are some simple steps to protecting the computer's motherboard, or mainboard, as it might also be called.

Signs of a Failing Motherboard Detecting the difference between a failing or failed motherboard and other failing components can be difficult. This difficulty arises because all the components of a computer are plugged into the motherboard. Thus, if you are having trouble seeing the screen, it could be that the motherboard is failing or that the video card is failing. For this reason, any part of the computer failing can be a sign of a motherboard failure. However, there are some more specific indications that the failure is the motherboard. These include the system randomly powering down, all the components of the computer powering up without a live image appearing on the screen and only certain components of the motherboard working. b> Causes of a Failing Motherboard b> As with most computer components, the most common culprit when a motherboard fails is heat. All computer components are particularly sensitive to heat, and the inside of computer can become quite hot. Over time, this wears out the motherboard and can lead to its failure. A second common cause of motherboard failure is electrical damage. Commonly this occurs during computer maintenance such as installation of new peripheral devices. During maintenance, if the technician has static electricity built up on his or her hands, it can discharge into the motherboard, leading to a failure. Electrical surges, such as those created by lightning striking a power line, can also lead to motherboard failure. This is most commonly prevented by using a surge protector, but some surges are powerful enough to overpower the surge protector and destroy the motherboard. The last common cause of motherboard failure is physical damage. This can be in the form of water damage or actual physical impact. Although the motherboard is typically well protected, a strong enough hit to the computer case or the introduction of water into the case can lead to motherboard failure. b> Diagnosing Motherboard Failure b> Determining that the motherboard is the cause of a particular symptom can be difficult. Although specialized tools exist to determine if a specific component has failed, the easiest method for determining which components are damaged is a simple bench test. This does, however, require having a second computer, or at least extra components. The method for this is to determine what possible causes could lead to the symptoms of motherboard failure. For example, if the system shuts down randomly, it could be the motherboard, the power supply unit, or connecting cables. In this case, you could plug the power supply unit into another system that is known to be working and if the problem persists on the other system, then the power supply unit is the likely cause of system instability. Similarly, if the computer powers up but fails to display an active screen, you can move the video card into a second, working computer and determine if the video card is bad. Then try using the good video card from the second computer in the damaged computer to determine if it is only the video card or if it is also the motherboard. Although this method is not foolproof, it is effective. b> Preventing Motherboard Failure b> A few simple steps can be taken to ensure the motherboard does not fail. While a motherboard may fail anyway, simply due to age or unforeseen circumstances, it is less likely to fail if you take a few simple precautions. First, ensure the computer is in a stable location where it will not be knocked over and will not be likely to have liquid spilled on it. Second, if any maintenance is performed that will expose the motherboard, use an antistatic wrist strap or discharge any static electricity before working in the computer by touching a grounded metal object. Third, keeping the motherboard clean and free of dust can ensure that it continues working, although some computer manufacturers do not allow the users to open the case during the warranty period. Last, ensuring you use a quality surge protector can prevent the motherboard from being destroyed by power surges. b> Laptops Laptop motherboards are more exposed to damage than desktop motherboards. Although they tend to stay cleaner, they are more likely to be exposed to heat due to the small case. They are also more likely to be exposed to impact since the computer is being regularly moved. When transporting a laptop, it is crucial to use a case designed for laptops that will prevent blunt forces from hitting the laptop. Also, many laptops have vents on the back and the bottom. As cooling the inside of a laptop is much more difficult given the confined space, ensuring that these remain unblocked while working on the laptop is critical. Learn where they are on your laptop and ensure you leave them unblocked while working and the laptop's motherboard should be effectively cooled. Hope this helps.

What is the best way for me to protect my billiard cue?

The best protection for your cue stick is to invest in a good quality case. I suggest getting a hard case, although more expensive than a soft case, they are worth the investment. A case will not only protect your cue from getting damaged, but it will also protect it from humidity and moisture.

my keybord stops working on my pc i have to take out the kord then it works but after a while it happens again

You have corrosion on the keyboard connector pins - either the female pins in the motherboard,
or the male pins in the keyboard connector, or some of both.

To address this, plug/unplug the keyboard & motherboard (carefully, so as not to bend these tiny
pins) several times, so that the friction caused by numerous plug/unplug operations will rub away
the (invisible) corrosion.

sticking a pin into the motherboard's female pin holes wouldn't be advisable, since the port's pin
diameters are tightly controlled, and a household sewing-type pin would bee too large, and
therefore damage the motherboard keyboard connector. If the motherboard keyboard
connector is truly damaged (for whatever reason), it can be replaced by someone with
soldering skills.

Also, move your PC to an area where there is less humidity in the air (the humidity promotes
the formation of corrosion), if possible -- but these
little corrosion problems in connectors can happen anywhere.

Laptop hinges

As far as the warranty coverage from Best Buy goes, it's a lot better than just what the manufacturer offers when you buy the unit. When you purchase the laptop, the sales associate is taught to offer you warranties of various dollar amounts depending on model. Some of these are standard PSP warranties (called PSP, or Performance Service Plan) and cover additional causes of damage such as heat, electicity, humidity, and dust. There is also a higher level warranty which Best Buy has offered for the past 2-3 years called an ADH warranty (or Accidental Handling) and it included the coverage of the PSP, as well as damage due to liquid spills (see: minor, not immersion) as well as damage caused by impacts.

This is where the job of a Geeksquad Technician can get complicated. We have to use our better judgment, experience of prior repairs, and best observational abilities to be able to help our customers with the correct response. If we just accept a laptop regardless of condition for repairs regardless of what type of warranty coverage exists, the Service Center has the ability to perform no repairs to the unit because warranty coverage does not apply to the nature of the damage. Then they will retroactively charge the customer a deposit fee, roughly between $24.95 and $112.95 depending on the unit...And this is just to be in receipt of their old unit, un-repaired. That is a situation we attempt to avoid at all costs to avoid causing grief and misery for waiting 2 weeks and have zero repair work performed for a customer.

So, now that I have explained their policies a bit better, let me help determine how you can have your laptop fixed.

Check your receipt carefully (Best Buy can reprint you a copy if yours is lost or hard to read). Search for the letters PSP on the bill of sale, and determine if the letters ADH are immediately next to them. This would offer you the maximum level of coverage for warranty repair.

If the Geeksquad technician viewed your lapotp's hinges and felt that it was damage caused by an impact or through normal wear and tear, it would not be covered by anything less than an ADH plan. I would suggest trying one of the following solutions:

1: Returning to the technician and asking him to send it to service as-is, with the intention of receiving an estimate from the vendor and pursing repair from a licensed repair technician.

2: Calling the manufacturer up directly, identifying the product and part, and inquiring as to the cost of a replacement plastic top lcd cover (you would be surprised at how expensive the manufacturer can quote these for). Then once you have ordered it from them you can return to Geeksquad iand have them install it for you (if you have previously determined they have a technician capable of performing that service and has adequate tools). Often times they will give you a discount on installation services due to the fact that you had purchased a warranty from them originally and they were unable to assist with the repairs prior.

3: Return to best Buy and have them pro-rate refund the extension of your PSP and use that amount to pay for shipping and deposit through the manufacturer, having them assist you with continued repairs.

Hope that helped.
