Hello! Thank you for your question. I am a licensed computer professional with over ten years of experience, and I will be assisting you today.

I'm sorry about the issue. Does the laptop have windows 7 or 8, etc.?

Is it the windows password? Is it showing your user name or email address at the log in / password *****?

Are the NUM lock and/or CAPS lock keys off?

Is it okay to reset the laptop fresh?

Please reply at the box below. Thank you

Windows 8.1

Thank you.

Is it showing your user name or email address at the login / password *****?

Are the NUM lock and/or CAPS lock keys off on your keyboard?

Is it okay to reset the laptop fresh?

It is not asking for my user and or using my e-mail address - just a block with 'enter password' only.


Are the NUM lock and/or CAPS lock keys off on your keyboard? Yes.


Is it okay to reset the laptop fresh? Yes

Is it like the image below:

Press & hold the power on/off button on the laptop for about 10 seconds, then turn it back on and check.

Thank you

Yes

Expert:  Viet - Computer Tech replied 2 years ago.
It's the bios/setup password. This requires opening the laptop and short the circuit. Are you able to remove the battery and memory cover at the back of the laptop?

How old is the laptop?

Thank you
Customer: replied 2 years ago.

Battery cover I can remove but not the memory cover - not sure where the memory cover is? The laptop is about 18 months old.

Expert:  Viet - Computer Tech replied 2 years ago.

Please see the two videos below:

Then jumper you want to short is JRST2501 or B500.

 

Please see the image below:

 



Please let me know. Thank you,

Knowing my expertise with a screwdriver I would probably short the enire system. Many thanks for your help judging by the expert showing how to short the system the area was not that clear & and I don't want to ruin the laptop. John

Expert:  Viet - Computer Tech replied 2 years ago.

You're welcome. I'm sorry. Here is an image of the jumper you need to short:

 

After opening the cover, you will see these two labels JRST2101 and JRST2001 just to the bottom right of the CMOS battery (the small round battery as show on the above image). Just to the left of those two labels are the solder points. It looks like two single solder points but there is actually a small gap in between each. Take a flat head screwdriver & fit a piece of folded tin foil to the end (or use a paperclip). You need to short out the pair that are closest to the CMOS battery housing; it's marked with a red circle in the above image. It's easy to make steady contact as you can support the screwdriver against the battery housing. Turn on the power and if you've shorted correctly it will go to the BIOS, password, and user show up as Not Registered. Then Save & Exit. That should work.

 

Also, here is the laptop's full disassembly instruction if you need:

You just need to remove the back cover in order to see the CMOS battery / jumpers location as show in the above image.


If you are not comfortable, you can ask a computer tech/shop to try my suggestion, or you can go to a nearby toshiba service center provider:
, and/or you can call Toshiba at 0844(###) ###-####br/>
