Re: no power on my VT-300ATX powersupply

If you're trying to just plug in the wall power cablem without connecting the motherboard it will not work. Switching power supplies need to detect a load (device) otherwise they will not put out power. Safety feature.....

I have a Toshiba Satellite laptop. The original adapter is 100V, 1.l3A input and 19V, 3.95A (DC). Can I use an adapter with 100-240, 1.1A input and 19V 3.42A output?

The input voltage doesn't matter - the 100-240 just means the adaptor will work in most countries.

The output voltage is the same, and the current is only slightly lower - so as long as the plug to the laptop is the same AND has the same polarity [+ and - in the same places on the plug] then yes, you will be able to use it.

Where is the fuse inside the power supply model fsp200

The unit is only 200watt and the fuse cost about $2,Thats if there one built into it,
The replacement power supply is about $20-00 NZD
Probably 20minutes to fix (for a novice) depending on their skill level and tools available,

BEST ADVICE Replace it

Power is something you dont want to mess with because it can kill.
The power packs are replaceable but people arent.
Be very careful and dont mess with the power.

I am an Electrician and I respect power.Misterdj

No power output from powersupply.

Power supplies are not meant to be repaired, as you can easily hurt yourself since the capacitors hold charge. If the fuse is good, and you reset the power supply by unplugging it and then plugging it back in and it still will not provide power, trash it.

Flashing orange light on front of my dell 5150 desktop, will not turn on, even after unplugging for one hour. when plugged back in, flashes orange, no fan, no power. JK

So basically you cannot get the pc to POST. Meaning you have just a black screen when you power on the pc, right?

First off, did you attempt to update BIOS before this happened. 90% of the time this is caused by a corrupt bios.

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button.
Try to boot the pc.

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker, put the powersupply in a different pc, or try a different powersupply in the problem computer.

Could be bad ram, motherboard, cpu, powersupply, videocard.

Mac Ibook Power supply problem

On Mac iBooks the orange light comes on when it charges the battery. Once the battery is charged it turns green. Im guessing the other powersupply was aftermarket or broken. EIther way, if it starts out green - recognizes the battery isnt full - turns orange for a while - then turns green when the battery is full, then the computer and powersupply are working perfectly. Enjoy your iBook!

Possibly, but I think it would be easier to go to radio shack or some similar shop and buy a 110->220V converter. Check the load it can handle; you might need more than one.

Also check the powersupplies on your appliances to see if they have a swithchable powersupply. Manby PCs have these, because it's cheaper to make one kind of switchable supply than two kinds of non-switchables.

There might be a sticker over the switch to prevent "stupid users" to try the switch to se what it does. If there is one, it should be marked 110/220.
