I have a LaCie d2 Quadra 500 gb. external hard drive. It is just over three years old. Recently, it suddenly stopped working. No light or fan when powered up, and the hard drive does not spin. No longer...


Hello,
this drive rarely has a power switch issue beside the fact that sometimes it gets misaligned and cannot be properly put in the ON position because of the aluminum casing. If you tried powering on while the backplate is removed and still nothing, look at the soldering of the power switch. If the switch connectors are still all in place, the problem lies more with the power module.
A total lack of power would usually result from the power module being "cooked", so look at traces of burned and cracked chips near the power supply connector on the interface board. If all seems good, make sure the power connector is also correctly soldered.
If the power module is burned, you can replace the interface by buying a used one, but in most cases it is easier and cheaper to buy another enclosure like you did.
Regards,

My computer went blank when turning it on


1) Computer isn't working, due to the Processor isn't working, due to a bad Power Supply.
Weak voltage power rail.

Enough power perhaps to light LED lights, and maybe spin fans, but not enough power to turn the Processor on.

Computer Power Supply's are rated in Wattage.
Volts times Amperes = Watts.
(Average computer power supply in a fairly new computer, is rated at around 300 Watts)

A) ALL of the LED lights combined, use less than 1 Watt of power.
B) EACH fan uses 2 to 3 Watts.
C) A typical Processor may use 51 to 125 Watts.
Depends on what Processor it is.

Power Supply with a weak voltage power rail, can have enough power to light LED lights, spin fans, but not enough to turn the Processor on.

Solution?
Test the voltages of the Power Supply,

Or, use a KNOWN to be good Power Supply, that has the correct amount of power cables, the right kind of power cables, the correct size, and shape of the case, and enough Wattage, for a test unit..

A bad Power Supply is one of the leading causes of computer failure.

EMachines T2824. Does nothing but light on mainboard coming on...


This is a motherboard problem. You'll need to replace it. Although, it may be cheaper just to buy a new PC (eMachines are never very expensive, or well-made for that matter)

I have a computer with an Intel D845GEBu2/D845PESV mother board. One day works great, next day no longer powers up. I changed out the PS, all I get is a small green light on the mo bd that lights up...


If all you get is a green light, and no fans, hard drive spin up, nothing on the monitor, well than, it could be that the power supply is the wrong one for your computer. Either that or the motherboard is shot.
double check on the power supply, that is probably the problem.

Acer veriton M460 will not boot up


The acer veriton m460 has three faulty capacitors. Check and see if you have bulgy capacitors. I have ten of these computers and all have three blown capacitors.

No power light when on but can hear running, no screen image


First make sure the monitor is on and connected to the PC.
If the power light is not on you could have a bad power supply, it could also be that the onboard video went bad.
If your PC has four trouble lights in the back, let us know which ones are lit, this can pinpoint the problem.
The noise you hear is the drive spinning up and the CPU fan.
Good Luck.

Hard drive will not spin.


I have the same problem with the same enclosure. I found out it is the power supply problem. It worked the first time out of the box. But when the black 12V/5V power supply box heats up, if I turn it off, and on again, my hard drive won't spin up. It had buzz sounds and tried to spin. I think they use a crappy power supply that can't supply enough current during drive spin up when temperature goes up.

My solution is to unplug the whole unit from the wall when you don't use it. That give the crappy power supply time to cool down, so next time when you turn it on, it'll start from cold. This solutoin worked for my 300G Seagate drive. For my smaller WD drive, it doesn't require cold start. I guess it makes sense, as bigger drives require more current to spin up.
