Here are some more information for Side Power:

To prevent damage to the DC input jack you need a plastic wire clip and one or two small plastic tie wraps. To Start have the plastic wire clip in hand and you may need to pry open wire clip a little to fit the diameter of your power cable into the clip. Then find a suitable place on the laptop to place the wire clip that won't interferes with other functions on the laptop or be in the way when you open and close laptop lid.

When ready remove protection paper from adhesive side of wire clip and stick clip on to laptop.

With power jack cord plugged in laptop slip cord into clip leaving some slack in cord between DC Power Jack input and wire clip. Now with a marker, mark power cord just before it enters wire clip on side of cord closes to DC power jack input.

At this point remove the cord and place the small cable tie on the section of the cord where marked, pull cable tie tight so it will not slide up or down cord. You may need to use needle nose or other pliers to be sure it is tight and will not move. When you are sure the tie wrap is secure and will not move you can then clip or cut the unused part of the cable tie. Insert the cord back into the clip.

Now I have a Warning and please read it.

The information here is made to be used to help reduce or prevent damage to Laptop DC Power input jacks when light or medium jerks or yanks are applied to the power cord. Heavy Jerks or pulls on power cord could result in Damage to laptop (example yanking power cord so hard laptop may fall of a table and hit floor or other such object). The writer of this article bears no responsibility for any damage to any laptop computer or computers or any other device that use information in this article for any reason.

Taking Care of Power Equipment and Carrying On in Stormy Weather

Power loss incidents, which amount in USA to $80 billion annually, cause tremendous   damages to computers and data, in industry, communication and data centers.Power failures are markedly related to season, occurring mainly due to transformer failures, standby generator starting troubles and underground cable malfunctions, all victims of poor maintenance that could be avoided.   

Forty two major worldwide Power Failure reported incidents were analyzed by UPSonNet.  All occurred during February 2009, each affecting thousands up to hundreds of thousands people. The study results indicate that most failures are due to defective equipment that failed in Stormy Weather. Proper preventive maintenance could have eliminated most defects and the associated power failures.

Normally, during the dry period, contamination which includes electrically conductive materials is collected on power line insulators. Rains and storms close the electric path causing shorts and arcs, tripping line breakers. Sometimes utility poles catch fire due to the electric arcs.

Salt is used in some areas as part of winter road treatment, increasing the amount of contamination spread by road vehicles kicking up salt from the roadway. This creates more potential for electric arcs near freeways and major roads.

Trees are also a leading cause of power failures in winter. Winds and snow cause trees to fall. The falling trees cut power lines. Some power lines create electric shorts and arcs between adjacent power lines or from power lines to ground.

Lack of rain may affect power supply in places where considerable amount of power is generated by hydropower. Kathmandu is now seeing severe power cuts, with no rain in the past few months and decreasing water level in rivers feeding the hydropower plants.

 Excessive heat, as experienced in Australia in February, overloads electricity supply due to tremendous growth in air conditioning, thus tripping line breakers.

Natural causes reported as air contamination, trees, ice, no rain, as well as any incident reported as transmission line failure, which may or may not refer to natural causes, form together only thirty five percents of total power loss incidents. Defective equipment is responsible for forty six percent of power loss incidents and is the main reason for power losses. Seven percent of outages occurred due to automotive accidents. The reason of additional twelve percent is unclear.

Although most installations are equipped with Uninterruptible Power Supply (UPS) systems, no single UPS or its battery failure was reported. In some cases the power failure occurred after depletion of UPS batteries. 

Till late eighties, year by year, the arrival of first autumn storm was accompanied by collapsing of defective UPS systems and particularly worn out backup batteries. No UPS Company had enough staff, or enough batteries to deal with all irate calls from customers. The chaos stopped when microprocessor based UPS control was introduced in early nineties, enabling automatic testing of UPS systems including batteries, by performing periodic power outage simulation exercises. The exercising enabled detection of defective systems, correction of the UPS and replacement of defective and weak batteries. All these preventive actions were performed when mains power was still available, before the stormy weather season. 

Equipment malfunction diagnosis indicates that nature is not to be blamed. Similarly to the described initial experience with UPS sytems, most of the studied power equipment, which failed during storms was revealed to be already defective, and couldn't perform within its designed limits. Lightning and switching voltages generated in the grid are generally attenuated and clamped to the insulation levels of line isolators and surge protective devices. Healthy transformers and cables should be able to withstand these voltage levels, and backup generators should start when needed.     

Performance of proper preventive maintenance can solve most of power failure problems. Simple, cost effective monitors based on technologies such as Partial Discharge (PD) and Infrared tomography are able to detect transformer defects, and allow scheduling corrective actions in time. Power outage simulation exercising can reveal generator's starting problems. PD methods, Power Factor measurements, as well as other monitoring methods, offered by test instruments manufacturers, can alarm before the stormy season, about defective underground cables, which require treatment. 

UPSonNet study reveals that most power outages occur in stormy season, mainly because of  defective equipment, which fails in harsh environment. Such outages, do not happen due to acts of God but due to negligence of humans, and can be avoided by proper maintenance service. Regular maintenance schedule, exercising and monitoring can foresee possible problems, which can be solved before the storms come.

How do I replace the drivers side power mirror on my grams car?

Someone had hit my grams 99 Ford Escort in a parking lot and her drivers side power mirror is hanging off. It needs to be replaced can someone please tell me how to replace it for her? Please tell me step by step on how to do it (I need the "dummy" version please for I've never done it before). Thanks sooo much in advance....

you will probably have to take the inside door panel off to get to the mirror nuts unless your lucky and there is just a small cover over the mirror nuts, anyway once you get the inside of the mirror exposed all you need is a 10 millimeter socket and ratchet to take the 3 10 mil. nuts off that hold the mirror in place and as you say it's a power mirror so there will be a wire connection to it that you have to unplug and then you can take the whole mirror off from the outside of the door, to replace just reverse the steps. Good luck.
