This works only for some models.

Power unit off. Disconnect AC power. Remove battery. Remove the memory cover screw, memory cover and the memory modules. Peel back the mylar. there should be a set of solder pads labeled JOPEN1. Short the JOPEN1 solder pads for 30 seconds. Replace mylar. Replace memory modules. Replace battery. Power up unit. If all is well, replace memory cover and screw. Hope this helps.

How remove bios password on toshiba satellite L3550-S7829?


visit Toshiba's Global ASP Locator at:http://pcrepair.toshiba.com

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 key while booting the system.

I have toshiba satellite LToshiba Satellite L505-S5966 PC Notebook L505 -S bios password forget need to remove


Hi

To bypass the BIOS password for your laptop press and hold Left Shift key and check if password is bypassed. If it is not then you would need to reset it. To reset the BIOS password you would need to remove the RTC battery on the motherboard and try and restart the laptop 2-3 times. With the laptop turned offf follow these steps--

  • Open Memory Cover
  • Remove Memory
  • Remove Black plastic insulation
  • Locate & Short CMOS CLR1 for 15 Seconds

  • Hope this helps... If it does please do not forget to accept the solution or post back for assistance.

    BIOS PASSWORD REMOVAL on a toshiba satellite L45 S7409


    This link describes the bios password reset for various Toshiba models (it's at the top of the results list), hopefully this will help you take care of your problem.

    I would also think that Toshiba support would be able to assist you with this should you call them.

    I have forgotten my bios password and can't get into my toshiba a135-s2246 laptop


    One solution is using a parallel Loopback plug. This is a simple device that plugs into the parallel port of the machine and removes the password when you boot it up.

    To make it you will need a 25 pin DB25 plug, take the plug apart and join these pins using some old cable;
    Pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, and 18-25

    Plug it into your parallel port and boot up your machine, the password should be removed as soon as it boots.

    Note: This will work on majority of older Toshiba's (1995 – 2002) and obviously only ones that have a parallel port.
