Question about Toshiba Satellite M45-S169 Notebook

Toshiba Satellite M45-S169 CPU Upgrade

I have been doing a lot of research after recently acquiring a M45 laptop (after repair of the once-dead motherboard, the C2 ceramic capacitor next to CPU was shorted and replaced, also replaced the Mosfet surface mount IC), and so far there is no documentation, no resource guide, nadda as far as hardware upgrade for the S169 model. Apparently wasn't an option for this model, may dissuade from their premium models at the time. The processor is a SL8MN Celeron 380 M 1.6Ghz 400FSB Dothan core with a 21watt power consumption rating.  
Then given these numbers to go by, would it be illogical to assume that the SL8U6 with almost identical specs (except for cache, 200Mhz higher clock frequency and the expected VCC increase) would be able to run on this setup? In maybe a minor flaw would be the core speed remain at 1.6Ghz, however that would still not be enough to negate the performance of the system. TDP is still the same 21watt.

With that being said, has anyone had any experience with the M45-S169 or M45-S1691 with upgrading the CPU? Don't worry about my experience, if I can repair the motherboard on this laptop (which ran me a whole $9.50 shipped from Ebay) I think I can more than qualify for a CPU swap. :)

    Luckily it is a Micro-FCPGA (non-soldered) socket, however the chipset supporting the 533Mhz FSB is unknown, the higher end models used the Intel chipset compared to the ATI chipset on this laptop.

    Curious if you swapped out for the pentium and ditched the celeron, I have upgraded acers and dells running amd chipsets, which m45 has ,but not seen any info with intel ,,or toshibas,



    My daughters m45 could use some pentium power in hers,



    Thanks

I have a M70 with Celeron 390M, I was able to replace it with a Pentium M740 1.73ghz/533fsb, the Bios is able to detect the new CPU but once Windows XP is loaded, it's running at 798mhz (133mhzx6) with multiplier set at 6 instead of 13. I heard so much about Speedstep suggestions, but I set the power seting at the highest, but all test resulted with CPU running at 798mhz at all time. Any more suggestion?

The chipset will support pentium M processors and some pentium 4 notebook processors. the bios should recognize the processor's new speed and should be able to support a 533mhz fsb. as long as your celeron is not soldered to the socket, you should be fine with the upgrade.

Port is DC Power Jack.

AC adapter (Charger) plugs into it. (DC_IN)

Example of the DC Power Jack,

http://www.dcpowerjacks.net/catalog/index.php?main_page=product_info&cPath=3_20&products_id=1628

Looking at the view all the way to the left, the jack is upside down in relation to how it is actually mounted to the motherboard.
All 4 of those prongs go down into the motherboard, and are soldered to the motherboard.

The prongs on the sides formed out of the metal case, are for support.
The prong all the way to the back goes to the Center Pin, and is the Positive connection.

The prong (Pin) in the middle, goes to the inner cylindrical shell within the DC Power Jack, and is the Negative connection.
(Along with the two outside prongs used for support)

Battery removed use a No.2 pencil, and with the eraser see if you can gently move the Center Pin around.
ANY perceptible movement means a bad DC Power Jack, and replacement.

If it seems the entire DC Power Jack moves around, it may be damage to the jack, or the solder connections for the prongs to motherboard, are cracked.
Cracked solder joints just means use a little rosin flux, and rosin solder to re-solder those solder joints. (Solder connections )

DC Power Jack checks OK, normal diagnoses would lead you to the AC adapter. (Charger)

Center hole is the Positive ( + ) connection, and where the Positive (Red) probe lead of a multimeter goes.
The Negative (Black) probe lead touches the cylindrical outside metal shell of the AC adapter's plug.

(Multimeter set to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.
If more than one DC Voltage scale, set the Function knob to the
0 - 50 Volt DC scale.

You should read 19 Volts (DC)
Have an assistant gently wiggle the cable from AC adapter to laptop, and power cord to AC adapter, as you check DC Voltage.
Any fluctuation in the reading means the cable, or power cord has broken wires.

http://www.amazon.com/G51jx-a1-G51jx-x1-G51vx-rx05-G60jx-rbbx05-G60vx-rbbx05/dp/B004CF4SEI


However due to your statements I'm willing to bet the problem is/are Power MOSFETS on the motherboard, and/or ceramic capacitors.

(Multi-Layer Ceramic Capacitors, and Surface Mount Device.
MLCC and SMD ceramic capacitors)

Information on the above using HP Pavilion dv6000 series, and Pavilion dv9000 series Notebook PC's, as an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Also go to the second photo down, that has the Alpha and Omega Semiconductor - AO4407 - Power MOSFET, circled in Yellow.

Below it, and to the right, are Ceramic Capacitors.
There is one above the one on the right, one above it, and one to the right of the top one.

Small rectangular shaped objects, with a dark wide band on the middle.

If visual signs of blackening, burning, or blistering, are shown on any of the Power MOSFETs, or ceramic capacitors, they need to be replaced.

Showing average cost of a Power MOSFET used a LOT in laptops, for this power application;

Fairchild Semiconductor International - FDS6679 - Power MOSFET,

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

$1.01 USD

MLCC ceramic capacitors used, are about 62 cents to 80 cents each.

Now price a replacement motherboard.

However, logic does sometimes dictate just replace the motherboard.
Why?
Because depending on electronic components that have failed, the damage could be further.

Or components may be weakened, and won't take long to fail after replacing failed ones.

Can you disassemble the laptop, and un-solder/solder the needed electronic components?
If so, and the repair fails down the road, just open it back up, and decide if a motherboard is logical.
(Price/availability)

IMHO (It's in my 'AOE', so that is what I would do)

My toshiba l300 freezes or switches off when i plug in charger...works ok on battery tho! ???


Suggest laptop has a problem with Power MOSFETs in the power section area of the motherboard, and/or MLCC ceramic capacitors that are nearby the Power MOSFETs.

!O_O!

Here's an example of the DC Power Harness;

[DC Power Jack is the jack on the laptop, that you plug the AC adapter (Charger) into.
(DC_IN)

For your model the DC Power Jack, is connected to wires that end in a plug. (Harness)
The plug plugs into a small white connector on the motherboard.
The DC Power Jack itself sits in a channel, along the outside edge of the Base Enclosure. (Bottom Cover) ]

Toshiba Equium L300 series of Notebook PC, motherboard general example; Top and Bottom views,

http://www.ebay.com/itm/Toshiba-Satellite-L300-L305-S5931-Intel-GL40-PGA478mn-Motherboard-V000138670-/160874593074?pt=Motherboards&hash=item2574df7b32

Scroll down to the Yellow 'frame', and click on the first photo shown,
[ Original Part - ebid-deaklz ]

Look at the Top Right corner, and at the mounting hole.
There is a aluminum looking cylindrical metal spacer below it.
To the bottom left of that cylindrical metal spacer is a white connector for a plug.

The plug to the DC Power Harness.
This is the power section.
Note the Power MOSFETs on the motherboard.

One to the immediate bottom right, of the white motherboard connector mentioned above, one above to the top left of the white connector, and close to the outside edge of the motherboard.

This is a general example of a Power MOSFET used in this type of application, and used in a LOT of laptops; (Not indicating this model is what your motherboard power section uses),

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

Note the eight J-leads used on both sides. (4 per side)

More information using HP Pavilion dv6000 series, and Pavilion dv9000 series Notebook PC's, as an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Note the second photo down with the Alpha and Omega Semiconductor - AO4407 - Power MOSFET, circled in Yellow;

To the immediate right of the AO4407 is a small rectangular object, with a dark wide band in the middle.
This is a Ceramic Capacitor.
(Multi-Layer Ceramic Capacitor, and Surface Mount Device;
MLCC - SMD)

There is one above it, one above that, and one to the right of the top one.

Now go back to the Top View photo in the Ebay link, and view the Power MOSFETs around the white connector, on the motherboard, for the DC Power Harness.
Also the MLCC ceramic capacitors.

If you see obvious signs of damage to the Power MOSFETs, or ceramic capacitors, such as burning, blistering, or blackening, they need to be replaced.

Or replace the motherboard.

In reality you do not know if the repairs you made 'will stay'.
Already burned out electronic components you replaced, may have taken out other components, or weakened them.

More logical is to replace motherboard, unless you are fine with opening the laptop back up again, and replacing the motherboard the second time around.

If you do wish to attempt repair, Power MOSFETs are about a dollar (USD), and ceramic capacitors range around 52 cents to 80 cents.

Take the Fairchild Semiconductor International - FDS6679 - Power MOSFET, for an example,

Toshiba satellite c655d motherboard componet x4701 blown


There are no fuses on the motherboard.

The X4701 may be a Macom RF Power MOSFET, and will probably be located close to the X4701 designation, silkscreened on the motherboard.
Doesn't EVEN look like a fuse.

This is a general example of a Power MOSFET,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

Notice the J-leads on the sides.

I wonder if you are looking at a crystal diode, or an MLCC ceramic capacitor, (Multi Layer Ceramic Capacitor, and is SMD. Surface Mount Device)

http://www.magnaquartz.com/wp-content/uploads/2011/05/crystal-diode.jpg

http://www.mouser.com/Passive-Components/Capacitors/Ceramic-Capacitors/Multilayer-Ceramic-Capacitors-MLCC-SMD-SMT/_/N-b2cj?P=1z0wrkiZ1z0t6fg

(Scroll down)

At any rate let's look at a Satellite C655D series of Notebook PC's motherboard,

http://www.ebay.com/itm/Toshiba-Satellite-C655-Intel-Motherboard-V000225020-1310A2355302-/251167301769?pt=Motherboards&hash=item3a7abce089

Under the large main views are small views.
The view to the far left is the Bottom side.
The third view from the Left is the Top side.

You have to click on each one, one at a time, then you can use the Zoom In feature for that view.
Using the Zoom feature, can you try to point out the electronic component?

Use a reference point we can both follow. State a known large component near it, and go from there.

You know what the processor socket, and graphics chipset is. They are covered by the Cooling Tube.
You know what Power MOSFETs look like now, and Ceramic Capacitors.
The small aluminum 'can's that have a purple mark on one side, are solid Polymer capacitors. (Doubt they are Tantalum)

Also, I realize that it gives one a sense of pride to repair a motherboard, and the cost of the electronic components are MUCH cheaper than buying a replacement motherboard, but a replacement may be the way to go.

(Fairchild Semiconductor International - FDS6679 - Power MOSFET is around $1.
Ceramic capacitors, (MLCC, and SMD), are around 60 to 82 cents.
From the Ebay link it looks like $39 to replace the motherboard)

Capacitor failure? Ehh. No problem if we're talking SMD MLCC ceramic capacitors.

Diode goes bad? Could led to power going to the wrong place, and other electronic components could have been affected.
Could be bad, or about to go bad.
Jus sayin'.

This would mean motherboard replacement is the more logical solution, IMHO.
Post back in a Comment.

Ihave mbx -160 ms70 sony laptop mother board ther is no power adapter is working pleas telme whatare the comapnents i have to chek in power section


A) Check the DC Power Jack.

The DC Power Jack is the jack that the AC adapter (Charger) plugs into. (May state DC_IN near the jack on the outside of the laptop case)

IF, I have it right, there is a DC Power Harness. The DC Power Jack is connected to wires in a harness, and the harness has a plug on the end. The DC Power Harness plugs into the motherboard.

http://www.laptoppartsexpert.com/i-131440-dc-jack-w-cable.html

[Instead of the DC Power Jack being soldered to the motherboard]

Remove the DC Power Harness, and with a multimeter set to OHM's perform a continuity check of all wires in that harness.
See if the DC Power Jack of the harness, is in good shape.

DC Power Harness checks out?
Problem is with the Power MOSFET's on the motherboard, or a ceramic capacitor, or two.

!O_O!

MOSFET,

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

Power MOSFET,

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

Don't know who makes the P.MOSFET's on the motherboard, or what manufacturer number they are.
They are however, located Near the connector on the motherboard for the DC Power Harness, and they have 8 J-leads.

This is an example of a Fairchild Semiconductor FDS6675BZ
Power MOSFET. One example of a P.MOSFET used in this application, on a LOT of laptops,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

Note the leads coming off of both sides. Those are 'J-leads'.

See if any of the Power MOSFET's, or Ceramic Capacitors, are burnt, and/or bubbled.

This gives you more information, but is using HP Pavilion dv6000, and Pavilion dv9000 series of Notebook PC's, as an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Here you see the two Power MOSFET's used. One on top of the motherboard in the power section area, one on the bottom of the motherboard.

Looking at the second photo with the Alpha and Omega AO4407, Power MOSFET as an example, look to the right of the yellow circled AO4407.

To the right is a Ceramic Capacitor.
Rectangular in shape, and looks like there is a black wide band across the middle. There are two more above it. See if one, or more of these are burnt.

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

That's right. A Fairchild Semiconductor FDS6679 Power MOSFET is $1.01 USD, without tax, and shipping.

Just an example of cost.

http://www.mouser.com/Passive-Components/Capacitors/Ceramic-Capacitors/Multilayer-Ceramic-Capacitors-MLCC-SMD-SMT/_/N-b2cj?P=1z0ynasZ1z0vhw8

Laptop freeze up and shutdown by itself, then can't boot up after


If it is still under warranty, you'd save yourself a lot of time and money if you just send it in for repair. If it isn't, the way to test if the RAM is bad is by trying to use the stick in another laptop or by trying to replace the RAM you currently have with RAM that you know is working (has worked on another computer). If the problem is with the motherboard or CPU, for most people it's better to just sell the laptop AS-IS with a good description on eBay and buy a new laptop.
