Question about Toshiba Satellite P25-S507 Notebook

1 Answer

Toshiba password locked

I was on this site before I contacted the fixya page, that was how I found out how to disassemble the laptop. I ran across a site that was a "how to" build a bios password reset tool made from a parallell printer port doing a crossover/solder 3 wires together. Have you ever used one or made one?
This is new to me

Keyboard sticking

Replace Keyboard.


Just an example. Search for the best price, and a reputable dealer.


A) Remove ALL power. Remove the AC adapter (Charger), and Battery.

B) In the Irisvista link above, click on the photo shown in Step 6.
Look at the Battery Compartment area at the top.
Note the two rubber 'feet' on each side.

The 3 screws that are circled in Red, and are to the inside of the rubber feet, should be removed. I think they hold the Keyboard Securing Strip on.

C) Follow Steps 8 through 12 on the Irisvista link above.
(You are on Page 1.
Page 1:: Page 2:: Page 3:: Find another model, is on the top of the page, and bottom of the page in White.

A note on the Keyboard Cable;

The Keyboard cable STAYS attached to the Keyboard. It removes from the motherboard's connector.

The Keyboard cable is a FFC. Flat Flex Cable. This is one general example of a Flat Flex Cable,

The thin metal strips on the end of the cable, (Will be motherboard connector side), are contact pins.
This end of the cable slides into the motherboard connector. It is on the opposite side of the Keyboard.

Before removing the Keyboard Cable from the motherboard connector, you may wish to make a mark on one side of the cable; and a matching mark on the Same side of the motherboard connector. (Sharpee?)

Even if the cable was twisted from the factory, it MUST go back the same direction it was removed.

The motherboard connector is a type of ZIF connector.
Zero Insertion Force.
It is rectangular in shape, and is composed of two parts.
HOWEVER, it does NOT come completely apart.

The bottom piece is the larger of the two parts. It is the BODY.
The upper smaller rectangular piece is the Locking Bar.

The Locking Bar moves. The Body is stationary, and mounted to the motherboard.
The Locking Bar works on a wedge type of principle, and when it is in the locked position, it wedges the Keyboard Cable in the Body.

There are two types of Locking bar used at present, to my knowledge. I cannot discern in the Irisvista photos, as to which type is used.

1) Sliding Locking Bar;

A) Locked; or can be said as Closed,

B) Unlocked; or can be said as Open,

Here you can see the Body is White in color, and the Locking Bar is Brown.
You can also see that there are essentially two 'tabs', of the Locking bar showing; on either side of the Keyboard Cable.

One uses their thumbnails to Gently ease the Locking Bar forward; and towards the LCD screen.

The Locking Bar ONLY moves about 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital O.

2) Flip Up Locking Bar;

A) Locked,

B) Unlocked,

IF, the Locking Bar is broken; and/or the hinge pins for the Locking Bar on the Body, are broken; you are looking at -
MOTHERBOARD REPLACEMENT, and why I am being so detailed.

I do not have access to my Toshiba laptop Service Manuals, anymore.
According to the Irisvista link there are NO screws, that come up from the bottom of the laptop; and screw into the bottom of the Keyboard.

However I wish you to look FIRST, before trying to remove the Keyboard.
If present these screw/s will be in an area under the laptop, that corresponds with the area of the Keyboard.

Generally are in the Battery Compartment, and can be seen when the Battery is removed.
May also be situated as stated, in the area of the Keyboard.
Usually they/it will have a K next to them/it, or Keyboard, or a Keyboard symbol.

For additional questions please post in a Comment.

Hi i have a Toshiba satellite m105-s3041 When ever i start the laptop,theres a blank screen in the background with a blue box in the centre saying enter password.......

This sounds as if the BIOS Password somehow got set. In the newer laptops it's easy to get to the CMOS battery, pop it out and wait about 5 minutes and then put the battery back in. Pay attention to how the battery goes back in by looking closely before you pop it out.

Unplug the power supply cord to the laptop. Remove the laptop battery. Push and hold the power button for about 5 seconds. This PDF will show you the location of all the 'doors' on the back of the laptop. Scroll down to the last page. The CMOS battery looks like a large watch battery.

I also found this at another site and it's worth checking the info on the Toshiba site. If this is true this is a known problem and Toshiba has a fix for it: "For all you so called arrogant techs out there who have assumed that most of the people who have had problems with Satellite A135-s2276 have stolen their laptop check out your info from Toshiba....There is a known problem ...A KNOWN PROBLEM pertaining to the password issue. There is a defect on several of toshiba models. There is no password...the bug in the bios causes the password prompt and toshiba has a fix for that problem which has to be applied before the problem occurs which can be downloaded from their website. Also if you are now experiencing the password prompt problem Toshiba....yes, Toshiba is correcting the problem at no cost to the customer. The website has instructions on how to have it done free by Toshiba and shipping info because you have to ship it to them they have acknowledged the problem. I had mine corrected....and it work just fine."

This being said, try the CMOS battery reset first and if that doesn't work, please contact Toshiba. I'm not positive but you may have to ship the laptop back to them for the fix.

My toshiba laptop is askingn for a password to turn on. I know this relates to the cmos battery. I have the toshiba satellite A215-S7413, how to i get to the cmos battery?

How to get to the CMOS battery

The Toshiba Satellite A215-S4747 Notebook PC's CMOS battery, is soldered to a bracket on the bottom of the motherboard.
The laptop has to be completely disassembled to access it.

In this photo showing the bottom of the motherboard, the CMOS battery is in the middle,

This is a link to a free Service Manual, detailing disassembly,

Go to the 11th line down. The one that starts with Satellite A10
Go across and click on A215

This is a PDF file. It may take up to 30 seconds before you see the first page, and additional time to fully download.
Suggest you let the file download all the way before looking through it.

1) Remove ALL power to the laptop. Remove the AC adapter (Charger) and Battery

2) Observe Anti-Static Precautions
Suggest you bu and wear an ESD wrist strap, and connect the alligator clip to a good ground source.
Average price is around $3 to $6.

3) Use a multi-compartment container for the various screws you will remove.
Mark each compartment for the area the screws come out of.
There may be as many as 60 screws and 12 different types.
Do Not mix them up.

(You can use a clean egg carton in a pinch. Mark each egg holder)

Intermittent power supply, problems whit the jack, how I can change that? thanks, Ing. Elton Vargas

1) Check to make sure the problem isn't the cable going into the plug, from the AC adapter. (Charger)
A lot of times, where the wires meet the back of the plug, that goes into the laptop DC Power Jack, is bad.
The wires have a break from becoming stretched. Makes an intermittent contact.
Same thing for where the wires meet the charger body.

AC adapter plugged into power, unplugged from laptop, use a multimeter set to the DC voltage scale.
Use the alligator clip attachments for the probe leads, attach the probe lead's to the AC adapter's plug, and wiggle the wire, check for an intermittent break.

2) AC adapter (Charger) unplugged from laptop, Battery removed, see if you can wiggle the center pin of the jack.
You may find the entire DC Power Jack will move a little.

If the center pin does not move, but the entire body of the jack does, the jack may just need to be
resoldered to the motherboard. The solder connections may be cracked.
If the center pin moves, replace the jack.

To replace the DC Power Jack, or repair the solder connections,

1) Remove all power to the laptop. AC adapter and Battery.

2) Observe Anti-Static Precautions:
Buy and wear an ESD wrist strap. (Electro Static Discharge) Connect the alligator clip to a good ground source. I connect mine to the metal frame of an open, empty desktop computer case.
(You don't need an Anti-Static Mat)
The price of an ESD wrist strap is around $3 to $8. Found in a multitude of places.

3) Completely disassemble the laptop down to the bare motherboard in your hand.
No Processor, Heatsink assembly, peripherals, nada.

A) You may wish to take photos, or make a video as you disassemble, for your first time. Also make notes.
After the first laptop the next one becomes easier.
(All of them follow a basic path when disassembling. Toshiba, HP, Acer, Gateway, you name it)

B) Use a multi-container for the various screws. Label each container for the area the screws came out of.
There may be 60 or more screws, and 12 different types of screws. Some look VERY similar to each other, but are NOT. DO NOT mix them up.
You can use a clean egg container in a pinch. Label each egg holder.

C) Take your time, use patience. Practice your soldering, de-soldering skills before working on the Toshiba's DC Power Jack, if you're rusty.
Use Desoldering Braid, and not a Desoldering Tool. (Solder S-ucker) The desoldering braid works MUCH better! (Also known as solder wick)

May take additional time to fully download.

Laptop screen has "enter password" after battery ran down

Toshiba's found a glitch with some models of laptops, where a password is set by "itself"
They have confirmed this issue and offer a FREE fix, that includes a BIOS flash, to avoid this from happening again.
You should call Toshiba and tell them that yor laptop has a BIOS password that nobody set.....they'll know what you mean..
Here is the number for this:

Hi, I need some help (BIOS locked)...

ok i found a couple more things...apparently you dont have to remove the battery.. I found this site that tells you two "jumpers" (solder squares) C88 i believe under the network card. But if you follow this link and follow the directions it will get you going again.

I don't know exactly at what stage you are at and i hope i didn't cause any trouble but this normally is how we take care of this problem. Unless once in a blue moon we come across one like this.
