What are you trying to do? Replace the CMOS battery, or reset a BIOS password?

This is what the CMOS battery looks like,

Now view this pictorial disassembly guide,

Go to the photo in Step 17, and click on it to enlarge.
See the CMOS battery in the middle/left?

Round silvery looking object. Go straight down from the red arrow to the far left.

That is how to access the CMOS battery.
(Yes I know it states Satellite A200/A205. Same for the A215)

Now BIOS password reset?
Do not know where the two copper pads are to briefly short out. Suspect under the Ram Memory modules, (And under a small sheet of Mylar plastic), or under the Wireless Modem. (And under a small sheet of Mylar plastic)

The links on this solution I gave may help,

[ Am I concerned that you may have stolen the laptop, or are trying to break into someone else's laptop?

I figure a thief would not risk this ]

To enter in to bios, try password Toshiba.

Also:
By UsingMS DOS Command: This methodworks only if you have access to the system when its turned on because thismethod requires MS DOS. Open Command Prompt from Programs menuand provide following commands one bye one: Debug o 70 2E o 71 FF quit NOTE:The first character in the above commands is English alphabet "o"and not the number 0. After providing the above commands, restart your systemand it should reset the CMOS Settings along with the BIOS password. If you arecurious to know how it works? then let me explain the above commands: In this method we are using theDebug tool of MS DOS. The "o" character present atfirst in these commands, outputs the values to IO ports. The number 70and 71 are port numbers which are used to access CMOS memory.By providing FF value we are telling CMOS that there is aninvalid checksum and it resets the CMOS settings as well as BIOS password. By UsingSoftware: There are a few software which canalso reset CMOS settings or BIOS password or both within a few clicks. But asstated above you should have access to a system which is turned on and shouldhave access to MS DOS or MS Windows: CmosPwd . You can download program on this page: http://www.cgsecurity.org/cmospwd-5.0.zip

You can reset bios password with 2 method.
(1) open back cover of laptop then find motherboard .Pull cmos cell from motherboard for 15 minutes then again put it in it's position .then it not ask for password.
(2)You can clear password with jumper settings find jumper on motherboard named clear cmos it has 3 pin .1-2-3
Put jumper in 2-3 position then again put it in 1-2 position then check .
Let me know if you need more assistance.
Thanks.

remove ac supply and battery from the laptop.. and press power button for atleast 30 sec.. it reset the CMOS memory.. this is what toshiba technical support person told me to do when i called to them way back..

You need to remove CMOS battery and leave it 12 hours as is. Try again see if cleared. Check if there is a reset button under laptop?
Google it how to remove BIOS password, you will come up some codes.

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.
Then it not want password.

You should be able to reset it by disconnecting the CMOS battery. Unfortunately, you have to partially disassemble the computer to find that battery. I really can't tell you where it is, but in some computers you can access it through the main battery enclosure. The motherboard may have a jumper that has to be reset to clear the CMOS memory or maybe just disconnecting the battery will do it.

unplug cmos battery then plug it back in make sure laptop is unplugged fist
