Hi,
You would need to take the Cmos battery apart for 10 minutes. There another way whit password cracker but it is more hard to do it. Try searching for Hiren Boot CD's. Thanks Let us know. Obed

Ugh. Toshibas are a nightmare. Most of them store the BIOS password on an eeprom (Electrically Erasable Programmable Read-Only Memory) chip. We did successfully get in to a Toshiba once by identifying the chip and removing it. But it's a lot of work and voids your warranty. Rumour has it that by shorting two pins on the chip you can reset the password that way, but it's never worked for us.

Afraid I can't help you more than that. Get someone with experience in electrical engineering to remove the chip for you if you decide to take that route.

Good luck

How to remove the cmos or bios password and want to remove the password in booting up, my laptop is toshiba satellite a135-s4527


The BIOS password is removed by the BIOS configuration, you need the BIOS password to get into the BIOS configuration.But if you do not have the BIOS password then you need to construct this dongle device.
TOSHIBA BIOS PASSWORD DONGLE
You can build a dongle that plugs into the printer port.Purchase a 25 pin male D sub connector and solder insulated wires to the various pins as listed below. The pins are numbered on the connector
http://www.tilman.de/sonstiges/toshiba/dongle1.jpg this is a picture of the finished dongle


Wire the pins as follows :-1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15
Plug the finished dongle in the printer port and power up the laptop. The password will be reset, go into the BIOS configuration to check the BIOS password, you may have to disable the BIOS password.

Toshiba A135-S4527 cmos battery dead


I found where the cmos battery is located. By the Toshiba tech support website , it's next to the PCMCIA Slot, just behind it. To get to it, Take off LCD, keyboard, top palmrest, hard drive, battery, memory, top power cover,switch board, modem, network. and some others. Too many to describe here. Items to remove not in order.
I Have the service manual downloaded already.
