 My client brought in her Toshiba Laptop

Model # C55-S5268

Intel Pentium Processor

500GB HDD

8GB Ram

Windows 10 v1511 

 

When I turn it on i get the "Toshiba" Logo then a Black background with a White box "Enter Password". This is NOT the Blue BIOS Password Box.

I can not get passed this to get to the BIOS. (pictures Attached) After 3 attempts it shuts down.

 

Here is what I have tried so far:

1. I have reset the bios by removing all power, Batteries (Including internal battery) to reset the BIOS. 

2. Entered Toshiba or TOSHIBA or 1234 as a password, still nothing

 

Hooked it up Sata to another computer as an external drive

 

3. backed up clients data

4. used the RegBack files to replace the SAM, and all other files associated in the C://Windows/System32/Config folder (Thinking this may be A Syskey hack)

5. Run Malwarebytes with 0 (zero) results

 

 

I have run out of ideas and I'm hoping someone else has had a successful fix for this.

Poster had the same problem here.  And here

 

This is a BIOS password and cannot be reset by removing the CMOS battery. Some Toshiba's can be reset by shorting solder points on the motherboard. Search youtube.

 

See this video. It doesn't show shorting solder points but it may get you closer to resetting the BIOS. I believe contacting Toshiba and showing proof of ownership will let them provide you with a master password.

Thank you JohnC_21, 

 

I had thought about this, however in all my research I could see that Toshiba's have 3 Solder Points that each board might have, This one has none of the Distinguishing Marks. I looked for JPW, D500, JP1, CLR1, CMOS, J1, J2, J5, J7, J9, C88, PAD500, C738, C5071, C561, JRST1, G1 or c513 and G2 or C514, B500, unfortunately none of these are for this motherboard. 

 

I am NOT the owner! I am the tech. I was trying to avoid calling Toshiba, but when all else fails.........

I have contacted Toshiba, They were of NO help what so ever! The guy I spoke to could only do basic troubleshooting. He gave me a new phone # to call that was supposed to be Toshiba Repair and that is a non working number. So back to square 1!

Are there any solder points labeled XXX. The image also shows B500 but possible on the client's computer it is simply XXX.

See this miniguide. I would advise the client that this is a last resort method.

JohnC_21 I cannot find a XXX Either. I have been able to jump older Toshiba's but this one being only a couple years old makes me wonder if it's even possible anymore. The "Resetting the BIOS Supervisor Password With Debug Command" you sent me to was interesting, but i cant even get to a command prompt to try that! I'm a little concerned about Bricking this thing now. Any other thoughts, suggestions?

I think at this point it would need to go to toshiba for a new BIOS chip. There was a poster on the forum who did it himself using a USB programmer off ebay but you need some serious soldering skills.

 

Edit: Is there JPW solder point on the motherboard or JCMOS. The link is for the p855 but perhaps the C55 is similar.

Edit Edit: Were there any solder points beginning with JRST besides the one you posted.

See my edited post.

 

Also I found this. 

 

Possible solution:

  1. Dissasemble the laptop
  2. Clip jumper wire to ground on motherboard (usually find this around a chassis screw hole)
  3. clip a paperclip to the other end of the jumper wire
  4. Run the paper clip across all the pins on the eeprom chip. (just run it over any chip you suspect it may be)
  5. Reasemble the Laptop

Thats it your done if you did it correctly you will have reset the chip clearing the passwords and the computer will start up and go into bios or windows as long as there is no hdd password as well

(also this is obvious but make sure you have no power or battery supplied to the mother board while doing this)

I saw this too, but doesn't that give the possibility of Bricking the MB also?

There is always that chance. You can tell the client if they do not wish to have the laptop sent to Toshiba there are the other options but with the risk of bricking the computer. I would have the client sign a waver if they decide to go for it.

Yeah, I don't see anything other than the two small solder points labeled "2" just to the upper right of the battery clip in the image.

You probably have seen this page but some Toshiba's require you to short the points while the computer is booting.
