Toshiba satellite a205-s5000 replaced the power jack still no power.
Looking up the DC Power jack for this model, shows me a Center Pin, and cylindrical metal shell; inside the jack.
Center pin is Positive, cylindrical metal shell is Negative.
Also shows it to be a DC Power Harness. Wires connected to the jack, and end in a white plug; that plugs into the motherboard,

Granted, the above is a A205-S4000 series.
(A205-S4577)

So...................
1) Am I to assume someone broke the female connector on the motherboard, that the DC Power Harness used to plug into?
Hard wired in this statement would reflect there was a DC Power Harness, soldered directly to the motherboard?
2) Or is your statement that the DC Power Jack itself, for your model; is soldered directly to the motherboard; and you hard wired the new jack in place; after cutting the plug off of the end of the new DC Power Harness? (And removing defunct DC Power Jack)
Plus; Is this an A205-s5000, or one of the A205-s5000 model series?
A205-s5800, A205-s5801, A205-s5803, A205-S5843, etc.
Yes.
Trying to figure out why this A205, has a DC Power Jack soldered directly to the motherboard, and is not using a DC Power Harness.
Why?
Have to make sure you are soldering to the right area, yet alone the correct contact points.
Don't know what I'm talking about? You unsoldered the DC Power Jack FROM the motherboard? Or the jack was soldered to wires, and wired to the motherboard.
Hardwired. The term can be used for either scenario.
That's the way it was originally?
K
Let's go on.
The DC Power Jack is connected to the DC to DC power circuit; on the motherboard. (Power/Charging circuit)
This circuit is near where the DC Power Jack is mounted, or where the DC Power Harness plugs in.
In the circuit are Surface Mount Devices that are prone to go bad.
One is the Power MOSFET's, the second are MLCC's.
(Multi-Layer Ceramic Capacitor.
They, and the P.MOSFET's, are SMD/SMT

Let's use the HP Pavilion dv6000 series, and Pavilion dv9000 series Notebook PC's, for an example,
http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html
These series of Notebook PC's use the;
Fairchild Semiconductor International - FDS6679 - Power MOSFET, and the,
Alpha & Omega Semiconductor Limited - AO4407 - Power MOSFET.
Look at the second photo down, with the AO4407 circled in Yellow.
Immediately below it, (Right corner), and immediately to the right of the AO4407; are MLCC's.
Smaller rectangular object with a dark wide band in the middle of it.
There is one above the one, to the immediate right of the AO4407; one above it, one to the Right of the top one; and one to the right of it.
There are also 4 smaller examples to the bottom/left corner of the AO4407.
Look to see if any are burned/blackened.
Example of availability, and cost of FDS6679, and AO4407,

Scroll down. One Dollar and one Cent, USD.

Here we see the AO4407 is phased out.

78 Cents USD.
Just to show examples of MLCC's that are SMD/SMT.
The examples I chose are 4.7uf (MicroFarad), and 16 Volts. (DC)

You can use a 25 Watt soldering iron, instead of a Soldering Station.

What is the power rating of your computer? What is the power rating of your adapter? Is it switch mode? It is possible that the power supply is not meant for your AC outlet eg is 110V when it needs 240V

Hi,
i,d suggest looking carefully around the top edge of the laptop base. your looking for a small slot, the size of a 50 pence piece. or a quarter dollar US.
this could be by the left hand-side towards the screen ( as Is On sony Vaios ) If you need a user Manual, they have them @ 7Manuals. @ about $7.00 Or £3.50p UK.
Payments via Pay-Pal Accepted.
Hope This Helps Mike @ compurepair.
SOURCE: Dual Processors for Toshiba Satellite A205-S5000 533Mhz FSB
you got a cheap laptop. maybe from walmart or some other store that was selling it for about $400. It doesn't have a processor that you can switch out. I'm sure it's horribly slow for Visa, so my advise would be to sell it and get something with a dual core.
SOURCE: toshiba satellite a205-S5847 cuts off while working
You could have an overheating problem, The CPU shuts down when it overheats and the laptop won't bootup until the CPU has cooled down.
The overheating problems are caused by a faulty fan or the heatsink/fan assembly is clogged with dust which prevents proper cooling.
Check the fan to see it it spins freely, if not (it has a bearing problem) then replace the fan. Also remove and vacuum the dust off the fan and heatsink.
SOURCE: satellite a205 died. will not power up at all. 2
Go to the Toshiba web site. They often extend the warranty on laptops with common problems.
