I forgot my bios password. i am using a toshiba  A135-4427.  what can I do? Can't get past password screen.

See this support document for details on how to rectify this problem.

thanks i will see if it helps.  that sucks its a very nice comp

ANd it still will be once Toshiba fixes your bios.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully.  There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Sir...i cant boot it from the cd rom because the laptop is asking for bios password first before booting up in any device...and about the jumper setting...there are no CLR,CMOS etc..on my laptop..is there any code number on the motherboard aside the word you have given...

Tony has listed several incorrect items in his post.  First of all not all motherboards have a clear cmos jumper and the ones that do are just as likely to have 2 pins as they are to have 3 pins.  Many don't solder actual pins to the board and rely on using a screwdriver or other metal object to short across two solder points on the motherboard instead.  This is a security feature to minimize the possibility of powering up a motherboard with the clear cmos jumper in the clear position which is quite likely to damage (or even completely ruin) an otherwise functioning mobo. 

Next, for security reasons some boards do not mark the clear cmos points on the mobo with any of the labels he mentions or any other markings that a user could easily figure out.  They would mark them with something totally unrelated and then note that in the repair manual to make it more difficult for the average person to find.  With the large number of stolen laptops this is a way to prevent the thieves from removing any bios passwords rendering the laptop useless to them and one of the reasons that Toshiba and other companies will normally require proof of ownership prior to resetting a cmos/bios and removing such passwords. 

With the size constraints inherent in laptops it's not uncommon to have to dissassemble one to quite an extent to get to the clear cmos pins/solder points making it difficult for the casual user to get to them.  

I'm guessing that his posts (the first two he has ever made on thos forum with one being a duplicate) is nothing more than a spam trying to sell you his recovery software package that won't even work in your case.

I don't know where he got the idea that most cmos batteries are soldered onto the mobo.  I haven't noticed that to be so.
