The device runs on 5 VDC. There was an optional adapter available that used the keyboard output, that simply tapped the GND & +5 VDC. On the jack, the interior is +5, the outer contact is GND. The easiest way to power the device is to tap into a free line from your computer power supply. Alternatively, a transformer with 5 VDC 100 mA output should do the trick.

There seems to be no power to our shredder.


Beverly, the power supply for shredder is probably bad. If it has a external power supply, take old power supply with you to a electronics shop and have them match it up for you, with a universal power supply.
Check the attached links,

How do I fix my power adapter?


Could be the capacitors that filter the final D.C voltage in the power apadter . If the capacitors fail the D.C voltage would have 50 or 60 hertz hum on it. If a diode has failed it could also cause a more severe pulsing of DC voltage. A oscilloscope would show up if the DC is being distorted but I do not know where you would get access to one. A repair shop maybe ?

I misplaced the power supply and need to find another but don


look at the specifications of the old power supply in the manual or on a sticker on the back of the unit. It should give a DC voltage and an amp value. Get any power supply that has the same DC voltage and same or slightly higher amp rating.

So i lose my Literati charger right after my birthday! I cant find it anywhere and i found my old t mobile charger and it fits perfectly. But i cant tell if its chargeing and it wont turn on! Please help...


Stop!

There are no voltage and amperage "standards" for low voltage connectors found on devices made to run from an external "wall wart" or transformer type charger or adapter. Just because a connector "fits" does not mean the power is 1) the correct voltage 2) correct polarity 3) correct type (AC or DC) or 4) can supply the amount of power needed to operate the device.

You may have done irreversible damage to your device by literally "grabbing any old charger that fits" to power it. Obtain the correct charger - or if unable to find one; determine the characteristics needed by the device - those variables are listed in 1 through 4 above.

You may find adjustable power sources that allow 1) changing of tips to fit the device, 2) a selector to choose from a range of voltages, 3) a switch to select AC or DC output and 4) the ability to plug in the tip backwards so that the polarity reverses. The last thing needed, is to know how much current in amps or power in watts is needed by the device. The charger / adapter should be chosen on its ability to supply this power continuously - never choose a charger / adapter that provides less than any of the electrical requirements; otherwise damage to the charger or device may occur - and if left unattended, could overheat and cause a fire.

I hope this helps and good luck! Please rate my reply. Thank you.

T6528 has no video. Using a working monitor, tried differnet video cards but still no video.


1) So you tested the monitor on a working computer? Reason I ask, is that you will be testing the monitor cable also.

If it is a monitor with a detachable monitor cable, suggest you test the cable also.

2) Each graphics (Video) adapter card has it's own specific driver.
The driver should be installed Before, the graphics card is installed.

Otherwise Windows will 'break it's neck', to find a compatible driver, from it's thousands of generic drivers.
Won't do. You will get a driver conflict.

Windows: 'Which driver do I use? These or THESE?"

Kinda' hard to do, since you can't see graphics on the monitor.

I would like to suggest you diagnose the Power Supply to start with. (After checking the monitor cable)

It may seem that the Power Supply is okay, but it could have a weak Voltage power rail.

Enough power to light LED lights, and spin fan's, but not enough power to turn the Processor on.

1) ALL the LED's use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor can use 51 to 125 Watts.
(Lower for older Processors)

The eMachines T6528 comes with an AMD Athlon 64 3500+, processor, that fits in a Socket 939 processor socket,

1) eMachines Support > T6528 > Specifications,

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T6528

2) Information on the AMD Athlon 64 3500+,

http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors#Athlon_64

Can use up to 67 Watts, or up to 89 Watts. Depends on what Core it is.
(Clawhammer Core, Newcastle Core, Winchester Core, Venice Core, Manchester Core, or San Diego Core)

(Also uses an MSI K8NGM-L motherboard. Below for specifications only,

http://www.newegg.com/product/product.aspx?Item=N82E16813130041 )

A) Not to down eMachines, (I have an old T1090 in my shop that works great), but they are budget computers, and use budget parts.
One being the generic Power Supply that is used.

B) The computer could be dirty inside, as well as inside the Power Supply.

The cooling components for the SMPS, (Switched-Mode Power Supply,) are it's Fan, and Heatsink's used inside.

Once a layer of 'Gunk' covers these cooling components, the cooling capacity drops tremendously.

Heat = Wasted Energy

The more heat, the more the Power Supply strains to keep up with the call for power.
Eventually hardware components inside the Power Supply fail, and the Power Supply is toast.

You can test the Power Supply voltages.
You can use a multimeter if available, or an economical unit can be purchased for around $5 to $12, that will suffice for testing.

You can also use a power supply tester.
One example:

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5250576&CatId=5471

Voltages produced by the SMPS used in a T6528 are,
A) 3.3 Volts (DC)
B) 5 Volts (DC)
C) 12 Volts (DC)

Testing should be done on the 12 Volt power rail.
11 to 13 Volts indicates a good Power Supply.
Less than 11 Volts means it's time to replace.

Orange wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts.

All the color coded Voltage wires, lead back to one individual power rail, for each Voltage produced by the Power Supply.

You can test any Yellow wire to test the 12 Volt power rail.

With a multimeter, the Positive (Red) probe lead connects to the power wire to be tested.

The Negative (Black) lead connects to ANY Ground wire.

ALL Black wires are Ground wires.
They all go back to one central Ground source inside the Power Supply.

[Power Supply unplugged from power before attaching probe leads. After connecting, the power supply is plugged back into power, and the Power On button is pushed ]

I need to know the voltage of Mutsumi D359M3D floppy and where?


The power cable connector to the drive has 1 red (5v DC), 1 yellow (12v DC) and 2 black (common center or negative) wires feeding the required voltages from the main power supply source. The power connector will only go on one way. I hope this helps.

Missing voltage?


alot of voltage adjustments at that high voltage are likely from another source that develops it like the the swith-mode power supply upstream on power supply board that feeds it ..look for burnt resistors in this case.. I bet your in the wrong circuit but u can test all wires and pins coming in for 200 volts. get a schamatic of it and find a good tech if u dont know what i am saying. ty crazylarry
