Came to work this morning...I had this problem, and after reading this, it ws determined that my problem was a toasted power supply...went to staples and purchased another one, for 45.00 and was back and running within the hour. Thank you!

You’ve just spent hundreds if not thousands of dollars on your new Computer, LCD TV, Cell Phone, Stereo, Refrigerator and the darn thing stop working.

1. Do your lights flicker in your home or office?
2. Does the power dip when you run the garbage disposal or use a power tool?
3. Does your internet turn on and off?
4. Do you have to triple click a webpage before it loads?
5. How many routers and modems have you used in the last year?
6. Do you seem to be breaking your computers every 6 month?


What Causes Power Problems?

Despite advances in technology, power grids across the country are struggling to supply reliable power to homes and businesses. The increasing occurrence of large natural disasters such as Hurricane Katrina, along with the growing demand for electricity, have put a significant strain on power grids and an increase in damaging power problems. If your home office or business has ever been disrupted by a power problem, it's not surprising. IBM estimates that 120 power problems hit the typical computer in a month—that works out to four per day! As a result, computer systems and electronics are under siege by more frequent blackouts, brownouts, overvoltages, surges and other power anomalies.

Thanks to the aging of the nation's power-producing infrastructure, these power problems are likely to become more and more common in the coming years. Local sources can also generate blackouts, brownouts, overvoltage’s and surges. For example, if your neighbor starts up an electrical motor or the office on the floor below you blows a fuse, a blackout, brownout, overvoltage or surge could result.

Line noise is typically generated by turning on other power-drawing devices connected to the same electrical system. Turning on florescent lights, laser printers or appliances, working near a radio station, using a power generator or simply working during a lightning storm can all introduce line noise into connected equipment. Ever notice the "snow" on your TV when you use a blender or a hair dryer? That's line noise being sent back into your electrical system and into your TV.

What are the Effects of Power Problems?

Blackouts, brownouts, power surges and line noise can result in computer system downtime or lockups, data loss, lost productivity, audio static, video snow, slow electronic degradation and ultimately catastrophic equipment damage.

Even in new structures, the power may turn off for a millisecond and cause problems with your network and in turn, cause problems with your computer.
• Bad wiring
• Good wiring
• Old style 2 phase
• New style 3 phase


Just about everyone who lives/works indoors will at some time loose power, even for a fraction of a second.

• Your new LCD TV failed after 6 months
• You refrigerator no longer recycles
• Your dryer went kaput
• Your new entertainment center went down
• Your computer stopped working
• Etc…

What can you do about it? Call an electrician? Call and complain to the power company? Sit there like a dummy and say, oh well? (90% of the people)

Go to your local computer or office supply store and get a battery backup power supply.
Not just a surge protector (which is the number one response most people give me).
Get a UPS backup power supply. Make sure you have the correct one(s) for the equipment you are trying to protect.

What is a UPS (uninterrupted power supply)?

An Uninterruptible Power Supply (UPS) System is a device that supplies battery backup power to computers and peripherals during short power outages, and allows systems to safely shutdown during prolonged blackouts. UPS systems also correct brownouts and overvoltages, stop damaging power surges and filter disruptive line noise.

How Does a UPS System Work to Protect Against Power Problems?

An Uninterruptible Power Supply (UPS) System provides comprehensive protection against all power problems. To further understand how UPS Systems protect against power problems, consider the different types of UPS:

On-Line UPS Systems

This is the highest level of battery backup protection available. Power is first broken down and then perfectly reconstructed by the inverter, which is "on-line" 100% of the time. There is absolutely no transfer switching time. This process completely eliminates incoming surge and line noise, adjusts high or low voltages, and produces perfect sine wave power.
Important UPS Features

There are a number of other factors important to UPS users beyond its standby, line-interactive or on-line design. Auto shutdown, battery runtime, number of outlets and phone line suppression could be critical factors in choosing a system for a particular application.
Unattended Shutdown Related Features:

Monitoring Ports (Standard vs. Smart Monitoring)—Many UPS systems can "talk" to a connected device and instruct it to shut down when power fails. Models with a monitoring port have this ability. Tripp Lite offers UPS products with two types of monitoring ports, Standard and Smart.
Standard Port (USB or DB9)—Able to send basic signals regarding "ON BATTERY", "LOW BATTERY" and "POWER RESTORED" conditions.
Smart "Enhanced" Monitoring Port (USB or DB9)—same as standard interface with additional data regarding voltage, temperature, load level, and more can be transmitted to the connected computer. Many of the larger Smart products also have multiple monitoring ports so that a few connected computers or servers can be automatically shut down in the event of a power failure. This feature is especially valuable in data centers, computer rooms, and in cases where a single UPS will support several servers or workstations.
Free Monitoring Software—many of the models that include a monitoring port also support free Power Alert UPS monitoring and shutdown software via download. It interprets the signals coming from the DB9 monitoring port and instructs the UPS to take the appropriate action. When the UPS transmits a "power failure" message, the UPS waits a pre-configured period of time. If power isn't restored by the end of the "wait" time, Power Alert saves all data and shuts down the connected computer or server so that no data is lost.

Runtime Related Features:

Expandable Battery Runtime—Most UPS systems for computer use are sized to run for about 5-10 minutes at full load. Certain applications, such as telephone and critical networking systems, often require much longer battery runtimes (from 30 minutes to over 8 hours). Several models offer extended battery runtimes by allowing users to connect additional battery packs.

Fax Modem/Surge-Only Outlets—Most home and home office PCs are equipped with a modem and several peripherals. Generally UPS protection is required for a computer and monitor only and all remaining items, like printers, scanners and other accessories, are connected to a separate surge suppression strip. Modem lines connecting to computers should also be protected with a data line surge suppressor. Rather than requiring users to obtain each of these devices separately, adding to the cost and desktop wiring clutter, Companies offers a number of UPS products with 'surge suppression only' outlets and RJ11 modem/fax line surge suppression.

How Can I Compare and Choose the Level of Battery Backup Protection I Need?

Now after reading this article, you don’t have any UPS protection, then it is your Fault. Without a backup power supply your warranty could be null and void.
Yeah?! How will they know?
1. Burn smell
2. Popped capacitors
3. Fried circuits
4. Appliance spontaneously combust

Yeah, well, my warranty protects for “any reason”, except in the fine print, Acts of God (or power companies).

What they don’t tell you

Most ups systems only last 2 to 3 years, and then you have to get another one. Why? Because they are Batteries!! So buying a used one from the swap meet is risky. Some companies offer up to $100,000.00 dollars protection insurance when you buy select products. Why? Because they already know the 89% of working electronic failure can be traced back to a power problem.

you should get a power surge protector and the problem may only be the PSU (power supply unit) which has a fan and a switch
