You should check the Toshiba WEB site for instructions to how to upgrade (flash) your BIOS, if you make a mistake you may not be able to repair or recover from your mistake.
I have done BIOS upgrades on a few computers. If your Toshiba has a floppy drive and you can boot up from this floppy drive then the BIOS upgrade needs to be downloaded to a boot floppy. Then boot up from this floppy and run the BIOS upgrade program. When completed, remove the floppy disk and boot up your laptop.
YOU MUST CHECK THE TOSHIBA WEB SITE AS THESE INSTRUCTION MAY NOT BE APPLICABLE FOR YOUR TOSHIBA LAPTOP.
For that first you need to open back cover of laptop reconnect RAM memory .
Then you need to upgrade bios.
For that download bios update from toshiba web sites then upgrade bios again then it will be working fine.
Let me know if you need further assistance.
Thanks for using FixYa.
There is a documented problem with this unit that sounds like what you are experiencing. In the link at: http://www.insidemylaptop.com/toshiba-satellite-a105-laptop-sets-bios-password-by-itself/ you’ll find a couple for links to possible solutions.
You can call Toshiba to explain your problem. As I understand it, they will remove the BIOS password at no charge even if the laptop is out of warranty. Both of the posted solutions have you doing things that are farily technical, either from a dissassembly standpoint or a software standpoint. If you don't thnk you'd be comfortable and have time to wait until business hours, I'd suggest you call Toshiba.
One you have it resolved you should upgrade the BIOS to the latest version by downloading and installing from the Toshiba web site to prevent it from happening again.
you have to open the memory cover and remove the two RAM s, after that remove a black or whit plastic film depending on your model, you will loacte for B500 marqued ( XXX ) or J1 you have at least short the two point with a flat screwdriver and put the upper memory and power on the laptop will holding the screew driver till you see the toshiba screen, if it doen't work just try again. it works 100%
Unfortunately, if you can't remember your bios password you'll have to reset the CMOS. This is usually done via a jumper on your laptops motherboard itself, or removing the battery on the motherboard while the laptop is unplugged and the main battery is taken out. Be very careful when opening up your laptop, make sure all the screws needed are removed, as they are easy to miss. If you don't feel comfortable opening up your laptop, I would recommend taking it to a certified technician.
