Question about Computers & Internet

Battery does not charge and does not provide backup power

I tried to power my Toshiba Satellite A205-S5000 notebook with an un-recommended more powerful battery. I must have blown something on the board, 'cause since then I cannot power the system with the battery even though the system indicates that the battery has 22% power.

Also the system indicates that the AC cord is plugged in and the battery is charging, but it does not rise past the 22% power indicated even after several days of charging.

I've used the battery to power another system with no problem.

Toshiba satellite a205 will not turn on is it the power supply regulator on top rear panel?


Check AC power cord, use a different one, also plug into different outlet. If that doesn't work power switch is bad. Or something else is wrong.

I have a Toshiba Satellite a205-s5000 that I replaced the power jack in. They sent me the wrong plug, mine was hard wired into the board so I cut and spliced the new plug to the wires coming out of th


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)

http://www.irisvista.com/tech/laptops/toshiba-satellite-a205/big/toshiba-satellite-a200-a205-17.jpg

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
Surface Mount Device/ Surface Mount Technology)

http://en.wikipedia.org/wiki/Power_MOSFET

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,

http://www.mouser.com/Search/Refine.aspx?Keyword=FDS6679

Scroll down. One Dollar and one Cent, USD.

http://www.mouser.com/Search/Refine.aspx?Keyword=AO4407

Here we see the AO4407 is phased out.
Using one of the cross-reference examples given,

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.

My toshiba satellite a205-5804 has a problem with the main board, when its plug in it freezes but when not , when is used whith the battery it works alright. a repair center told me is the main board, but...


Are you using the original charger or a universal replacement? As loose fitting power plug can cause this problem but so can a loose connection at the power jack (repairable) or a cracked trace on the main board from stress at the power jack (not usually repairable - ie needs a new board). JC

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.
