I can not bypass BIOS passward for toshiba sattlit A105? My PC is looked. Note: I removed the battry and no changing on it,

You can fix this by removing first removing all power, then remove the plastic cover above the keyboard, removing removing the two keyboard screws.
You'll need to fold the keyboard in such a way that you don't damage the cable.
You will see the wifi card just to the right. It's the only card there. It is held in place by spring clips. Remove the card from the connector.
There are two solder contact points labeled "C88". Connect the power adapter to the laptop now. Short the two contact of "C88" and press the power on button. The unit should boot to the windows screen. Once it boots, you'll have to update to the latest BIOS.

somebody set the bios password to reset the bios password open the back cover of ram u see a small battry like a coin remove it fo10 to 20 second and remove laptop battry at same time then plug the adapter u will see baios was reset if u have any qury plz tell me the laptop model no and manufacturer

I think it came with a 512M on a 533 mhz bus speed (ddr2) and it supports up to 2G DDr2 on 533 ..Pay attention on the bus speed if you want to upgrade...and not insert anything else but 533 mhz cause you may experience problems with it ...I suggest not to use teh maximum either ..but if you have already a 512 M in one slot ...just buy and use another 1H module in the other slot ..and will be working great ..even on windows & ..which require at least 1G of ram ..
Good luck ! ..and please rate my answer ...

Here's how to reset password

Resetting a Toshiba BIOS Password KeyDisk will reset the BIOS password on Toshiba laptops.
Older Toshiba laptops can be convinced to boot without their power-on BIOS password by attaching a dongle to the parallel port which crosses a number of the pins. The pin out is:
Pins 1-5-10 2-11 3-17 4-12 6-16 7-13 8-14 9-15 Some Toshiba's can be convinced to bypass the startup BIOS password if you hold down the <LEFT-SHIFT> key while booting the system.

Here's a very good article. I couldn't put it better myself:
