Battery not charging

Power supply sent a spike.replace power supply

A) You did use an ESD wrist strap, and have it's alligator clip attached to a good ground source, right?
That way you don't have to worry about Static Shock issues, and frying out your laptop.

No?
You may have an expensive paperweight now.
(Although the motherboard does make a pretty good Frisbee)

Use any type of Anti-Static Precautions?

You did Follow Anti-Static Precautions? Good. Let's go on.

A) DC Power Jack

1) Battery removed check the Center Pin of the DC Power Jack. Does it move?
2) Cracked solder joints of DC Power Jack to motherboard?
Yes, means disassembly again to check.

B) Cables (Wires) are routed SPECIFICALLY through Channels and Latches.
1) Are they, or is one or more pinched by being in the wrong place?

C) Power On button board's FFC installed, in the SAME direction as when it came out? Lock Bar in place to keep FFC locked in?

FFC = Flat Flex Cable.

As you know it has no connector on the end. The motherboard has the ZIF connector. Zero Insertion Force.

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

The flat contact pins of that FFC has to line back up in the ZIF connector on the motherboard, the same way it was when removed.

Broke the Locking Bar on the motherboard's ZIF connector, or the Body of the ZIF connector?
You're looking at motherboard replacement.

Post back in a Comment with your findings.

Borrow a different 19V charger from a friend see if its just your charger if not then the DC jack most likely is damaged common issue with Toshiba and Acers. Good thing is Toshiba does not solder the DC jack it fits in a sleeve and plugs into the board.The Dc jack should run you around $5-$15 dollars the repair is a tare down to the boards right corner. Look on utube for "A75 tare down" should be a video floating around show you where the screws are. Shop would charge right around $100-$125 dollars if more they are ripping you off.

Curious problem. Let's start. I don't think that the mobo is responsible for the problem.

1. How much time does the battery in full charched condition can hold Toshiba at power on mode?
2. Is it possible for you to use a multimeter (voltmeter) to check some things for me?

Stelios.

You need to have the pins tested to see if the notebook is still sending a current to charge the battery. Take to a electroic shop and ask them to test the battery pins in the battery compartment. They will know how much current is needed to charge the battery. If the current is not their or not enough, you will have to send your notebook in for repairs. The Motherboard will need to be replaced.

According to specs on cNet, it has 3 USB 2.0 ports.

hello loyd516,

Have you tried a new battery? They are much much cheaper, and a whole lot easier to replace than a motherboard.

Here are replacement batteries that I found searching with Google.
http://www.google.com/products?q=Satellite+A75-S206+battery&hl=en

According to Toshiba, there has been a battery recall for your specific model.
If that is the case I would definitely contact Toshiba support about it. Maybe you will get a free battery out of the deal. Who knows.
Here is the link and the list(your model is highlighted)

hi there,

you can follow this instruction and try to your laptop to resolved the problem.

A bad connection between DC-IN power jack on the system board and the system board is a very common problem with Toshiba Satellite M35X and Toshiba Satellite A70/A75 notebooks. If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it’s still under warranty, it would be fixed at no charge to you.
Problem symptoms:

1. Laptop randomly shuts down without any warning.
2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
3. The battery will not get charged.
4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

To fix the problem, you have to take your laptop apart, remove the system board to resoleder or replace the DC-IN jack. Toshiba Satellite M35X and Toshiba Satellite A70/A75 disassembly guides will help you to remove the system board. Take a closer look at the power jack on the system board with a magnifying glass. In most cases you get the power problem because of a bad connection between the DC jack and the system board, you’ll see a crack between the DC jack connector and the system board.
Here is an example of Toshiba Satellite M35X power jack. The crack occurs between the DC jack pin and the system board.
In some cases the connection is good, but the DC jack is bad itself. You can find a new DC jack for Toshiba Satellite M35X and Toshiba Satellite A70/A75 laptops here. Search for DC jack M35X or DC jack A75.
How to resolder laptop power jack yourself.
UPDATE:
Sometimes, after you replace the jack, you can see that the system board doesn’t get power at all. The battery will not charge and the power LED will not light when you plug in the AC adapter. So, here’s a possible explanation.
When a connection between the positive pin and the motherboard breaks (cracks), the power jack gets loose. You can feel it when you plug in the adapter plug. A loose power jack can damage the trace inside the hole in the system board. Take a look at the picture.
As you see, the positive pin goes through the hole in the system board and you solder it on the top side. Right? What if the trace between the top side and the bottom side is broken somewhere inside the hole? I’ve seen it before a few times. In this case everything looks nice and clean on the top side. When you plug in the AC adapter, you get normal voltage readings between “+” and “-“ pins on the top side, but the power DOESN’T go to the motherboard at all, because there is no connection between the top and bottom sides. Test with a multimeter if there is a connection between the top and the bottom.
If the trace inside the hole is broken you still can fix it. You can run a wire to connect the top and the bottom sides. Be careful not to short something on the board.
Update:
Here’s another solution to fix the power jack problem, it shows how to relocate the power jack outside the laptop base. Check it out here: Toshiba Satellite A75 failed power jack workaround.
When you repair a loose power jack, it’s a good idea to check the jack on both sides of the motherboard. When you remove the top cover from a Toshiba Satellite A70/A75 laptop you can see only points where the jack is soldered to the motherboard as it shown on the second picture in this post, but you cannot see the jack itself as it shown on the first picture.
Removing the motherboard from Satellite A70/A75 laptop is a good idea because the jack itself might has a broken “+” pin, as it shown on the picture below. If the “+” broke off the base, you’ll have to replace the jack.

The toshiba laptop has ways of checking if it will not charged

check the battety light if it coming on when it is plug in
If the not meaning the battery is bad
If the lights comes up and the computer is still not charging the battery test if the compter will power without the battery if it will then battery is bad
If the computer will not turn on even the lights on the panel shows activity then you can conclude that the AC adpter is bad

Go to CONTROL PANEL / POWER OPTIONS / POWER METER. Is the battery charged or charging?

If POWER METER says the battery is charged, you have a motherboard problem. Take it to a tech.

Do you have a voltmeter?

Remove the battery and check for voltage at the laptop's battery contacts, while it is plugged in. No voltage = charging circuit defect. A blown internal fuse or other motherboard problem. Take it to a tech.

Voltage OK or no voltmeter - take it to a tech.

A qualified technician should have a schematic and other technical documentation for your model It can be rather difficult (expensive) and hit-or-miss to locate possible fuses without the factory paperwork.

Good luck.
