Where is the jumper to reset BIOS on Toshiba Satellite P855

I have done a lot of research on this. I have disassembled the laptop, removed the ram, but do not know which jumper to short. Survey says I'm looking for "b500" or "xxx".

Does anyone know which jumper to short to reset BIOS password on Toshiba Satellite P855 series?

Here is what it looks like when the memory is removed:

Should I attempt to short those two solder points on the middle left side?

EDIT

I believe it says password reset is JPW. I have tried jumping JPW and JCMOS as shown in the image. No dice on password reset.

The JCMOS is the jumper you are looking for.

Reference 1

Reference 2

The jumper to reset the bios password on the toshiba p855 is labeled JPW. It's right next to the RAM slots. Easy to spot.

Just remove the casing protecting the battery + RAM + HDD + WIFI card, remove both ram sticks. Put one ram stick back into the top most slot. RAM is needed for the PC to run. I tried different combinations of shorting both the JCMOS and JPW jumpers, entering the bios [ which is allowed once after shorting the JCMOS with no hard drive plugged in ] , and removing the HDD.

I was using screwdivers with no success. I ended up using some copper wire and the above combos and eventually tricked into working.

If anyone else is having trouble with this leave a comment if more information or pictures are needed

I have the P855 model and I found on my laptop, JWP. JPW So all I have to do is tough these two copper circles together? I tried with a paper clip and a screw driver and it didn't work. No sure if there are more steps I needed. initially I took out battery, 1 RAM card + HDD + WIFI card as mentioned above. Do I need to hold down the power button for a long time? Will anything appear on screen once the power button is pressed? I still ended up seeing a black screen once I pressed the power button once.

With no visual, I connected the RAM + HDD + WIFI card back with no luck. JWP2

I own a Toshiba laptop satellite L670 and you just have to short the two copper pin close to the Jcmos for ten seconds then plug the power, press the start button and finally have it back to normal but the password is still needed.
