Compatible Toshiba System Boards?

I have a Toshiba Satellite M35X-S149 laptop. I need a new system board. I have found several system boards on-line that say they will work with my Satellite model. The two I am looking at are the K000019630 and the K000019660. I would like to know if either part will work with my laptop. The specifications given on the website are the same for both but there must be something different to have two seperate part numbers. My existing system board has a part number of K000019660. I am asking this question because there is a $50 difference between the boards - the K000019630 being the least expensive. Would the K000019630 be compatible? Let me know your thoughts. Thank you, Ray

Hi Ray !

I would not risk to buy on-line system boards for two reasons!

ONLY when you get it, you will know if it FITS in the chasis, and if it WORKS after you connect all wires and parts, but i believe you'll have to pay for it before!

Try to get some help from Toshiba support first!

Also, you just mentioned the difference between two boards you have on-line, but not the price.

Did you ask Toshiba how much will cot you a new board?

If there is acceptiable difference, buy a new one !

Regards.

Fig.1 Toshiba M35X bottom view - the memory cover is seen at center left and secured by a single screw.

(3) remove the (1) screw securing the memory cover.

Fig. 2 Toshiba M35X laptop shown with memory cover removed and HDD (Hard Disk Drive) removed, and with the HDD cover flipped up.
The RAM (SO-DIMM boards) are visible at center left.
The HDD cover is seen at the bottom of the photo.

(4) Using proper anti-static/static control techniques, clip alligator clip or your anti-static wrist strap to a frame ground of the laptop at an I/O connector or frame ground under the HDD cover.
(5) carefully remove (2) old 256 MB SO-DIMM DDR333 memory modules.
Store old memory boards in the anti-static plastic baggie in which the new memory boards were shipped.
(6) install (2) new 1GB SO-DIMM DDR333 boards, for total of 2GB of system RAM.
(7) reassemble system, and boot OS (operating system).
The laptop's ROM BIOS will auto-detect the new RAM and begin a standard POST (Power-On Self Test).
(8) If OS is MSWindows, it will also auto-detect the new memory, and allocate it to application software.

The technology of the Toshiba Satellite M35X-S349 memory module is called
DDR333, meaning DDR (Double Data Rate) SDRAM (Synchronous Dynamic RAM), at a memory bus speed of 333 MHz.
The Form Factor of the DDR memory card is SO-DIMM, which stands for Small Outline DIMM (Dual In-line Memory Module) (see photo).

Fig.3 Each 1GB SO-DIMM DDR333 memory module will look like this one.
The Toshiba Satellite M35X-S349 supports a maximum of two SO-DIMM memory modules.

Each memory module can hold (a) 256MB, (b) 512MB, or (c) 1GB,
in the SO-DIMM Form Factor compatible with the Toshiba M35X-S349 Notebook PC.

My laptop wont charge


There's several things that cause this:
- Your ac adaptor could be dead - use a spare one or but a replacement and test. - The power jack on the laptop could be damaged - you need to have a specialist replace this for you - The battery could be dead - test with a spare battery if you have one - If all else fails it means that the motherboard has malfunctioned and needs to be replaced.
It is highly suggested that you bring this system to a professional for repair or purchase a used one with the same specs and swap out your hard drive as it could cost you hundreds to fix this problem. You can buy a used, working one for $250 ob buy it now on ebay, or cheaper if you buy one on a regular auction: http://cgi.ebay.com/Toshiba-Satellite-M35X-S149-1-5GHz-512GB-Ram-60GB-HD-/320664896971?pt=Laptops_Nov05&hash=item4aa91e05cb

TOSHIBA M35X-S149????????? charger went inside the computer how do i fix it??? any help will be greatly appriciated


when you say the charger went inside the laptop that the piece that you plug into felll in. You have to open the case, get your soldering iron out and hot. Once you take off the bottom portion of the case you may need to remove the board to get to the plug piece. Once you get there you need to soldier it back on.

Screen black & with no power


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.

Motherboard replacement Toshiba laptop


Are you sure the ac adapter is providing power to the system? You should check it with a multimeter first before ruling out a problem with the system.
