Attempting to reset the bios password on dell insiron 1525

The 1525 uses a eeprom type chip. Removing the power via the Mitsu CR2032 button cell will do nothing to reset the bios password. Believe me I have been there done that. I am sure you can jump the cmos on the motherboard but have yet to find a soul that knew the chips location and/or which pin's to jump. I believe I've located the chip and some transistors located left of the battery.(But I could be wrong)! even if I was right...I'd have no clue which to jump. I have This Inspiron 1525 is a Bi*&%. Any one with labeled schematics of this board could possibly help. I have the board info for all to see, its as follows:
Intel ds2 48.4W002.031 not sure if this even cross references with intel being a Dell. Other option would be to know a L2 dell tec, read the numbers then their generator will cough up a bios admin password... "Anyone with that algorythm or the generator already compiled"? I'll Buy It!!!!! lol Look Hope this was helpfull and for my sake I hope an expert could help me with this one! I promise it will be worth it!
Any way If I can help anyone or likewise just shout! l8ter all!
Here is a photo close up showing what I believe to be the cmos chip just left of the button cell.

Hi!!Usually DELL passwords are stored in eeprom memoriesthat has to be read or writen to remove / bypass the BIOS password!!! Passwordgenerate a hash code that will appear after 3 wrong password attempts and ithas a 5 digit decimal format "xxxxx"


Another way to obtain password is by generate a unlock code or master password from the service tag that comes with the laptop in the bottom in the sticker (service tag "xxxxxxx")


http://www.laptoprebirth.comThey can calculate a master password with the hash code or the service tag. Hopeit helps

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

Your bad luck ... Id dell and IBM bios password is saving in a small non-volatile memory. So you cannot clear it by a jumper or CMOS battery removal. Specialized people can only do the same (contact laptop motherboard repairing vendors)

Removing the BIOS battery did not reset the BIOS password because the BIOS password is stored on an EEPROM chip. visit laptopmasterpassword.net

Bios info on hard drive


The BIOS password is not stored in the hard drive.
Try Dell as the password first.
The BIOS password could be stored in the BIOS chip or an an EEPROM chip.
If the password is stored in the BIOS chip, you can restore the BIOS back to the default setting and remove the password by removing the BIOS battery for 1/2 + hour, insert the battery and go into the BIOS configuration to set the Date & Time.
If the password is stored on the EEPROM chip, there are no backdoor passwords available.

User password lockout


Hard disk password is set from the BIOS. It is usually set in conjunction with the Power On Password. This password is stored on the EEPROM chip and is very difficult to crack - no backdoor passwords. It is used to prevent unauthorized access to the laptop and the data on the hard disk. Removing the hard disk and inserting it into another computer will not allow access to data without the HDD password.
