Regarding my Bios password
I asked a previous question here that my dell Inspiron 1545 is locked and I forgot my bios password. I also asked that is the bios password stored in the CMOS battery for which I got the answer that bios password is stored in flash eeprom.
So I wanted to know that if I will remove the flash eeprom from my laptop will it remove my bios password completely or not?
Please answer.

Yes, pulling the CMOS battery out, turn on the laptop for a few seconds, turn off the PC, then put it back to make it reset the BIOS setting, but you had to set up all the boot devices again (except USB, or CD).
If you remove the flash EEPROM, careful because it may make your BIOS unusable.

Welcome to the Dell Community @Kunar
Sometimes removing the CMOS/BIOS battery can reset the BIOS password.
On your model I am not sure if it will work.
I was looking for your model yesterday, in my warehouse, so I could test it but was unable to find one.
I will look again today but till then try this.
Disconnect the AC adapter and remove the MAIN battery.
Remove service cover on bottom.
Remove any memory installed.
Under the memory remove the black plastic.
Look for 2 contacts that look like this.
Use a small flathead screwdriver to short the 2 contacts.
If no contacts try this next.
Does the laptop produce a hash code???
xxxxxxx-xxxx
It can then be used here.
