It should be marked on the fuse or the board either next to or under the fuse. Before you replace it, find out what blew it. Otherwise, you could blow something else out.

Is there a power input fuse on a Toshiba Satellite C655D?


no, there is no internal fuse, unfortunately- because this sounds like a dead motherboard. the aftermarket power supply could have been over-volting, or delivering unsteady power- burning the motherboard.

OR the old power supply shorted, and blew the motherboard's power circuitry, and you were just running off battery power when you first got the replacement.

please keep in mind that, at times, the physical power input jack on laptops can also break, or come loose from the motherboard.

No start after reassenbly to clear cooling fans. lights come on. no fans when start is pushed no action at all.videoed disassembly to insure correct re assembly according to toshiba A75-S2131 specs by


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

Not advertising, using for reference. (Photo views)

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.

I cannot charg the battery I have toshiba satellite laptop A75-S206 ; and i can,t charg the battery tanks @ regard


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.

Laptop only runs on battery even though p/s is plugged


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?

My battery charger for my toshiba satellite L355-S7900 won't work


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.

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.
satellite-m35x-crack.jpg satellite-m35x-contact.jpg 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.
power-jack.gif 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.

Toshiba Laptop wont work unless plugged in, i recently bought a new battery think that the battery was the problem and still it doesnt work unless its plugged in. please help me!


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.

Toshiba Satellite L15-S104, Model PSL10U-01X02F--A COMPLETE LEMON! 2-14-08 I purchased a Toshiba laptop in May 2005 at Best Buy in Montclair, California and all was good for a short time. Less than a year later I began to have so many problems. I took laptop to Best Buy Geek Squad and the hard drive had to be replaced! I had an extended warranty, so not any cost to me. I continued to have problems with the laptop and in took my laptop back to the Geek Squad in January 2008 and was told the laptop needed a motherboard at the cost of over $600! The warranty had ended. I have called Toshiba apx 4 times and finally given to a case manager and left on hold each time from 10 to 17 minutes! I have left messages and not anyone has returned my call. I have requested that my laptop be replaced. Christine Honea-Takata CHoneaTakata@msn.com Ever since I bought my laptop in December of 2004, I've had nothing but problems. My laptop overheats and shuts down repeatedly, the screen freezes, my sound only works 75% of the time, etc, etc. I have a stack of paperwork from the Geek Squad for numerous repairs - they've replaced everything at least once, some parts multiple times. They finally told me it was a lemon and that they were sending it in so that I could get a new lap top....6 weeks later I hadn't heard anything and called them - the usual waiting on the line, talking to 4 different people, them saying they'll call me back. A few days later I still hadn't heard back from them so I called again - same run around. They then told me that my lap top wasn't a lemon and that there was nothing they could do for me. I bought an extended warranty (3 years) and it's been in every few months - also meaning I'm without my blimmin' lap top for at least 2 weeks at a stretch. After my warranty ran out, I "gave up"...what more could I possibly do? The machine was a lemon from the start but Toshiba won't own up to anything. However, I know there was a class action law suit filed...haven't heard anything about it for the past year or so. I wouldn't touch a Toshiba with a ten foot pole. Terribly disappointed, angry and frustrated. I've lost huge amounts of data and had nothing but problems with customer service.
