SB600 will switch on but no ready light and won't flash (constantly showing standby mode). I have tried several different batteries to check they are charged etc ... ps I have 3 speedlights and this is...


It is strange that all three units have the same problem. I am assuming that when you tested your three units that you did so by attaching them to your camera. If all three are bad, it could be that the problem is in your camera. Let's disregard the ready light for the moment because the ready light could be bad or your flash is only partially charging. As an experiment, turn on one of your SB-600's and after allowing time for it to charge, short out the contact pins on the flash shoe. If it flashes, it could be the camera at fault.

The SB-600 is an older unit. If you have three of them, I will assume that you are using them professionally and they have had heavy consistent use. As a result, your speedlight's capacitors may have reached the end of their life span.

Let's look at what may be happening. By charging, it means that the batteries in your speedlight are supplying a low voltage to a capacitor bank that charge to a higher voltage that is sufficient to fire the flash tube. All capacitors deteriorate over time and use and will lose their ability to charge and maintain a charge. Given the age of your equipment, that may be the case. If you have the knowledge and equipment, I would replace the capacitors on one of your units and see if it works. If not, I would send one of the units into Nikon for a free repair estimate. They can be reached at 1-800-645-6687 9AM-8PM EST, Monday to Friday.

LAPTOP WILL NOT POWER UP, IT HAS THREE FLASHING BLUE LOCK LIGHTS FLASHING


The only time I've seen this in the past is when its a bad motherboard. This repair runs between $250 - $350. If your laptop is more than 3 or 4 years old, I recommend purchasing a new one instead.
If you want to be sure its the motherboard, call a computer repair shop and ask how much they charge for diagnostics. Most charge $20. Don't take it to a big brand name store like best buy or comp usa.

My hand held Dyson vacuum will not charge. Every time I attempt to us it I get 3 charge light on the side flash?


My same symptoms are - after starting charge, Red light is on, then second light turns On. Then for a long time nothing happens. And later I have all three LED flashing.
I replaced battery and nothing changed.

Imeasured Power Supply voltage and found it 24.2v instead 28v as it stated on the label.

I opened it up and found that the three-lid chip marked 431 is faulty.
431 is a voltage shunt, which sets and controls output voltage.
You can use AIC431CUS or TL432 (TL431 has different pinout).
I replaced mine and volatge back to 28.25v and charger is now working as it should.

You can also use any TO-92 431 chip - there is enough room for it.

Good luck!

Continuous alternating one green and three flashing red battery


note.gif NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer. Check the battery status light — If the battery status light flashes orange or is a steady orange the battery charge is low or depleted. Connect the computer to an electrical outlet.
If the battery status light flashes green and orange, the battery is too hot to charge. Shut down the computer, disconnect the computer from the electrical outlet, and then let the battery and computer cool to room temperature.
If the battery status light rapidly flashes orange, the battery may be defective. Contact Dell _I found this on : http://support.dell.com/support/edocs/systems/latd820/en/ug/index.htm Hope this helps and good luck. if i "fixed ya" please rate me. thanks-jmattes

1721 Inspiron shows flashing amber, three times, then blue.


The cells in the battery are starting to go bad which is why the light is blinking the way it is.

Once you get a new battery put in there the light will stay blue instead of flashing amber.

Laptop won't power on


Hello,

Here is the manual in PDF format, that might have the error codes for the three flashing lights. Most likely you are experiencing hardware failure and should look into finding a free Hardware Diagnostic testing software that can be downloaded and booted off a cd.

Have a great week,

Flashing device status light


Ok the lightning bolt is your power indicator: solid green-charging, Flashing green-fully charged, flashing red-low battery, flashing red three times the once green-bad battery. the "trash can" looking one is your hard drive activity indicator it will flash while your hard drive is reading and writing.
