How to reset toshiba satellite l655d-s5093 bios

Put Recovery Disk 1 in the CD/DVD drive, then power off your computer, unplug everything from the unit including the AC, remove the battery, press and hold down the power button for 30 seconds, replace the battery and then AC, power on, at the Toshiba logo screen press 'F2' to enter the BIOS Setup, in setup press 'F9' to load setup defaults, press 'F10' to save and exit, now at the Toshiba logo screen press 'F12' to enter 'Boot Sequence', with the up and down arrow keys to select 'Optical Disk Drive' or 'DVD/CD Drive', you will then see 'Press any key to boot from CD/DVD drive...' with the dots counting down, press any key before the count down finishes. Assuming you get back to the Toshiba Recovery Utility menu, select the 'factory default' choice, and return your unit to its out-of-the-box state.

To reset or format HDD go to Toshiba website, support, find Toshiba HDD utilities, or Google third party free utils, install on USB, boot from USB, format and done.

That's sort of like trying to put the toothpaste back in the tube. Try the Toshiba Support forum: http://forums.toshiba.com/t5/Computer-Troubleshooting/Satellite-L655d-S5093-will-not-start/td-p/306230

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

Try a "Cold-Start",Remove all media, DVD, CD, USB..etc., Remove AC plug, Remove Battery, Hold down on/off button for 10 seconds, Replace battery, Plug into AC outlet,Push on/off button and Start normally.
IF THAT FAILS, try F-8 during pre boot, try to get to safe mode, or F12 to enter restore /recovery. After each try cold start, remove battery during this process.

Buy a drive cleaning CD/DVD, those from dollar store may also work, clean the drive a few times and it should read CD/DVD.
Alternatively look at the Toshiba support drivers fro firmware update to your specific drive. Make sure you get all the recommended and critical Toshiba updates.

This is the User's Manual for the L655-S5098 laptop:

Predictably, its useless when performing maintenance such as keyboard replacement, but page 82 indicates that this laptop supports "most USB-compatible [external] keyboards", so, while the chicklet keyboard is down, you can boot and use the system with a workaround USB keyboard.

I could not find an L655-S5093 laptop model on the Toshiba support web site, which is found at http://www.pcsupport.toshiba.com

The closest I could locate for you are these two How-to Guides:

Here's a teardown of the Toshiba L645/L645D laptops:

Here's a teardown of the Toshiba L675D laptop:

Chris Hingee is absolutely correct. Even if you reset the laptop bios password, you will not be able to reset the hard drive bios password. That old hard drive is your new paper weight after you purchase a new hard drive.

Don't worry i will help with the solution
