First of all, I know that support does not offer assistance with BIOS passwords due to the possibility of theft. But my request is legit (how many times have you heard that). A co-worker brought this laptop to me - purchased for use on her family farm - a cousin who was tossed off the farm for lots of less than pleasant activities apparently put a BIOS password on the laptop and killed the screen. I can get the laptop to boot using an external monitor but am immediatly asked for a password. I have seen sites that after so many failed attempts you get a code and can do things with that code but this simply gives a system halted message. Any chance of someone out there having any ideas? Removing the battery for several days did not help. Thanks in advance, Chad Hi, Try to rest RTCRST# point. in the Mainboard,. make sure that you do not short circuit any other Points,.

HI, Yes you need to remove the AC adpater & the Battery, but not requred to remove the HDD or the CMOS battery, but removing the CMOS battery would be put you in a safer side, RTCRST# is just 2 Points on the MBD(Pic as attached by #Sharanji), using a Wire or just need to Connect the 2 points for 2 -4 seconds,. thats it,.

Nobody has any idea whay they're talking about, every method mentioned is over ten years old and useless. Since you can't boot, you're likely screwed, but there one possiblity. First and foremost you need to gain control of boot, so you can clear the password for BIOS access. So we first need to try to remove at least the boot password. Physically clearing CMOS probably doesn't work, as the password is saved onto the BIOS ROM itself. Download the BIOS update for the machine. Extract the bios file from the .exe and do not change its name. Prepare a FAT16 or FAT32 filesystem flash drive with nothing on it. Place the BIOS file (.fd file usually) in the root of the flashdrive (only file, no directories on flashdrive) Rempve the battery, and detach all USB devices if any, from the non-boot machine. Have the AC adaptor nearby. Be sure the machine is powered off. Plug the flash drive into a USB port on the machine. With the machine powered off and without it's battery, press and hold the [Fn] + [ESC] keys. (Sometimes its the [Windows] + [B] keys but i've found the first to always work. Do not release keys and attach the AC adaptor to the laptop. After a few second, without releasing keys, press the power button. It should act somewhat funny and suddenly shut down. After it does that, you can release keys. Then wait a bit, and reattach battery + other stuff and try to boot. Hopefully the first password will be cleared. The next one is easy. Do a full bios flash from DOS clearing CMOS and password region on the ROM.
