You need to take out the battery, take out the bios battery, and then short the contacts of the bios battery holder to ground. If you don't, the capacitors on the board will still hold voltage and the bios won't be cleared. (This is the same thing the BIOS reset jumper does on desktop systems.)

Hi.
Usually there´s a backdoor password
Quote:
Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.
AMI Backdoor BIOS Passwords

Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
Award Backdoor BIOS Passwords

One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.
Phoenix Backdoor BIOS Passwords

Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.
Backdoor BIOS Passwords from Other Manufacturers

Reported BIOS backdoor passwords for other manufacturers include:

Manufacturer - BIOS Password:
VOBIS & IBM - merlin
Dell - Dell
Biostar - Biostar
Compaq - Compaq
Enox - xo11nE
Epox - central
Freetech - Posterie
IWill - iwill
Jetway - spooml
Packard Bell - bell9
QDI - QDI
Siemens - SKY_FOX
SOYO - SY_MB
TMC - BIGO
Toshiba - Toshiba

Remember that what you see listed may not be the actual backdoor BIOS password, this BIOS password may simply have the same checksum as the real backdoor BIOS password. For Award BIOS, this checksum is stored at F000:EC60.

I have never ever had a backdoor BIOS password actually work, but it's worth a shot.

Well...i´ve been searching for that laptop solutions.And it´s not good!
As it seems that those laptops have a password storage separated from the cmos (i thought it was strange that clearing it didn´t work).A solution that i´ve seen is short circuiting them:
Quote:
ThinkPad 570 [2644]
1. Power off the computer.
2. Remove the DIMM cover on the bottom side of the computer.
3. Short-circuit the two password pads.
4. Under the short-circuit condition, power on the computer and wait until the POST ends.
After the POST ends, the password prompt does not appear. The power-on password is removed.
5. Reinstall the DIMM cover.


Someone with the same prob:

As you see you have a big prob.

He did not do the short circuiting, he used a password cracking software that was taken from a diskette.
