You should get a error code. You can buy a service on Ebay and for about 13 dolllars you would give them your code and they will give you a code to unlock it.

SOURCE: Hp compaq 6910p BIOS Bypass

I removed the keyboard, unplugged the bios battery, holded down the power button about 30 secs, plugged back the bios battery, assembled the computer, didn't plug the battery and instead of that just plugged the ac adaptor and the bios passwd was gone =)

SOURCE: toshiba notebook HDD problem

I think you may find your hard drive has failed? I suggest that you replace the hard drive with a new one. But, just to check.. remove the hard Drive from the machine... (usually acessable under the machine via a couple of screws and usually just slides out etc) Then try to "Boot" the machine from CD or floppy.. (on say ya Windows XP CD, choosing Boot from CD from PC menu) if it does.. then it IS ya HD, if not then ya may have a Motherboard fault. So do NOT change the drive.. at this juncture I would suggest ya go to a reputable PC repairer and ask for a "Quote" for the fix, and an explanation of what is/was wrong.

SOURCE: default bios password toshiba satellite a135-s2276

I have a Satellite A135-S2356 that had the same problem. I tried the solution from PCTServices above and it worked great.

"Power unit off. Disconnect AC power. Remove battery. Remove the memory cover screw, memory cover and the memory modules. Peel back mylar from JOPEN1 solder pad. Short 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."
Just short the two little solder pads and it worked great! I thought I would have to send it back to the manufacture but I am back in buisness. Thanks for the help.

what you need to do is pull both the laptop battery as well as the cmos battery. in some instances, the battery can be pulled, but on other models, i have seen the battery as an actual physical part on the motherboard or somewhere where it is not easily accessible, in which case you need to clear the cmos by using a jumper on the motherboard, since it is a laptop, they are all different. you may need to see if you can locate a copy of the motherboards schematics and go from there.

it's the 'clear cmos' jumper you need to move on the motherboard. If you move that over one pin for a moment, then back, then boot up, your p/word will be cleared.

To unlock your BIOS you have to remove your BIOS battery for few minutes which is onboard, then replace the BIOS battery again on the motherboard will not only reset the BIOS password to default but will put all the BIOS settings to default. For which you will have to reconfigure your BIOS settings, but remember any wrong setting in the BIOS may damage your laptop.

I HAVE A TOSHIBA SATELLITE L355 S7831 AND I FORGOT MY PASSWORD TO START THE BOOT OF THE COMPUTER AND IT GIVES ME 3 GUESS' AND THEN SHUTS OFF??? WHAT ITS ASKING FOR IS A CURRENT PASSWORD?


Hello,

When you installed the system, you entered a BIOS password.
There is nothing you can do to bypass that password. The only solution is to take laptop to Toshiba Certified Service Center to have password disabled.

Hope it helps
