There is no overload circuit on these. This probably did in the board, however, it may have just got the processor. Start there.

Can i use any charger on s505


The Toshiba Satellite 5205 series of Notebook PC, and the S505 series model; uses an AC adapter (Charger) that produces 15 Volts DC.

http://www.sparepartswarehouse.com/Toshiba,Satellite,5205,PS520U-31P1RV,Laptop,AC-Adapters.aspx

You will see AC adapters sold that show 15 to 24 Volts. (DC)

http://www.duracelldirect.com/toshiba_satellite-5205-s505_ac-adapters_laptop_ac-b20h.aspx

This is because the AC adapter (Charger) has PFC.
Power Factor Correction,

http://www.hardwaresecrets.com/article/Everything-You-Need-to-Know-About-Power-Supplies/181/2

Also I see it is just a two pin AC adapter plug, to laptop.
Center hole is Positive, outer metal cylindrical metal shell is Negative.

Go for 75 Watts or higher though, and not a 65 Watt model.

[ On the case of the AC adapter;
Input: 100 ~ 240 VAC 50-60Hz

Means it can use from 100 to 240 Volts AC, and either 50 or 60 Hertz.

Output: 15VDC 6A

Means 15 Volts DC at 6 Amp's. (Amperes)

Watch the outside dimension of the cylindrical part, and the center hole dimension. Outside cylinder may be correct, but center hole may be too small. Or vice-versa.

WHERE CAN i GET A POWER SUPPLY CORD FOR THIS PRODUCT


Are you looking for the cord that plugs into the the electrical outlet that connects to the external power supply? Or are you are looking for the external power supply as well? If you are looking for just the cord itself, they should be common item that you should be able to purchase and any appliance store.

If you are looking for the cord and the external power supply, there are many online outlets that you can look like ebay, etc. You need to search for a 15 Volt 4 amp universal power supply. I would recommend the universal power supply since it will come with multiple adapters plugs so you should be able to find the right one to fit your monitor. Also note the polarity of the the plug otherwise it might damage your monitor.

I plugged the wrong power cord into my SVP T-800 camcorder.


Wow mate, not a good move that one, you may have fryed the main PCB by the sound of it, unless a fuse was in line some where within the camera, though I feel this would not be the case. You may have no choice other than send it to makers for repair on this one, because as well as putting too much power in, it may have been the wrong polarity too.

Ibook g4 rebuild


Hi there.
Make sure you have the voltage and amperage right first before you try and power up the motherboard.
Most laptop motherboards run on 15, 19 or 20 volts and take a different amperage like 3.42A for example.
The power in will be displayed underneath the ibook so take a look there.
Don't plug a 24 volt power supply into it unless it specifies that because you could damage the board.

Good luck with project

Fried HD?


Yep, it's probably fried, a little too much juice went in.
While the drive itself might be ok, the external casing is another story.

Try opening the case and removing the HD and plugging that in on your PC directly as a slave drive.

I would have to guess that you have fried the power supply, that would be the board where the power cord connects, there should be a 15 amp fuse around that connection so check for it. This may need to have a tech look at....

Replacement External Power Supply


So the old power supply doesn't have the output voltage, current and polarity noted on the label? What a ripoff! *grin* Did you look on the case near where it plugs into the monitor? Sometimes that will tell you the voltasge and polarity. Poliarity? Get that one wrong and the monitor could be cooked instantly! But it's usually positive. I found a completed eBay listing that had this info: "the power supply which the seller used to power up this Planar Flat Panel is inventoried as follows: ViewSonic 12V Power Adaptor Model # SYS1126-5012" I looked that one up, and it's listed as 12V at 4.17A. PC Hub has them for $28.62: http://www.pchub.com/uph/laptop/345-19804-2285/AC_Power_Adapter_5V-12V_Others_SYS1126-5012.html Good luck!
