Question about Toshiba Satellite M35X-S149 Notebook

1 Answer

Toshiba M35X I'm having the power jack problem issue no power to anything. Computer is dead and no lights on front. Wiggeling the plug does not do anything. Resodering did not help. With the power jack removed from the motherboard, I check between the positive and negetive with an ohm meter and I'm getting no reading. Shouldn't there be a reading there? Thanks, Jeff

Are you getting voltage from the AC adapter without the jack? I use a paperclip since the probes don't usually fit into the center.

Yes you should have voltage between the terminals on the jack with the ac adapter plugged into it. You may have a bad jack. There are many places on the net where you can get a new jack.

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.

I am working on a Toshiba Satellite M35X-161. when i press the power button, it lights up, fans and hdd spin up. and then it kills the power after about 3 seconds. i have tried re-seating the RAM and...


Have you checked the DC jack where the power adapter plugs in. With the adapter plugged in, wiggle it and see if you get movement. Hold it upward and turn your unit on, if the power stays on, then it is the DC connector on the motherboard that is loose.

If your fan is working correctly, then check your ram. But experience has shown me that an issue like this is usually motherboard related.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Problems sounds like a damaged power pin from pulling or jerking on the AC cable. I use a Cable Retention Device like the one in this video to keep from hurting the pin.

Call Toshiba immediately. Ask to ship the computer to the depot including the AC adapter, to determine if problem lies on the AC of th DC in jack. M35X has an extended warranty until 11-7-2007.
