Removing power on password dell inspiron 1545

how can I remove the power on password on a Dell Inspiron 1545. I read somewhere about jumping bios chip legs. Which chip on the motherboard is the bios chip?

ive done that before by just taking out the little battery and powering the board up

Folks, we're talking about a laptop... there are some BIOS/CMOS password cracking software with UBCD4Windows...otherwise pull the laptop battery and remove the CMOS battery, usually under the keyboard, and wait a few days for the various capacitors to discharge...

Yeah pull the little battery out of the mother bored make sure you no where the clips are 1st dont wanna break a clip. but best and easy way

A tutorial on Dell Inspiron Power on Password reset has helped me:
Solution 1: Recover Inspiron password in Safe Mode (in XP)
A. Press F8 when PC starts. Select “Safe Mode with Command Prompt” and Enter.
B. At the login screen with PC user accounts, choose one accessible account to login. The Administrator account (default/built-in) password is blank if never set password for it before.
C. At Safe Mode, Dos command displays. Input “net user” and Enter to list all the user names in Windows XP computer. Then input “net user XXX 123456” (xxx is the locked account name and 123456 is the new password set on this account) and press Enter. Then we will see “The command completed successfully.”
D. Input “shutdown -r” and press Enter to restart the system, then we can access “XXX” account in normal logon mode.

Solution 2: Dell Inspiron password recovery by accounts with administrative rights (Windows 7)
A. Login PC from the accessible account with administrator privileges.
B. Start - Local Users and Groups – lusrmgr.msc in the Search box - ENTER. If there is prompt for an administrator password or confirmation, type the password or give confirmation.
C. Local Users and Groups - choose Users.
D. Right click the account needed to reset password, and then select Set Password.
E. Input and confirm the new password.

Solution 3: DIY a Inspiron recovery disk to retrieve lost password
If we can not override password with the first solution, opting for Windows Password Recovery software will be the most effective way to unlock forgotten Windows password. Take Ainorsoft Windows Password Recovery tool as example.
A. Download Windows Password Recovery and burn .iso file to a bootable CD/DVD/USB on an available PC.
B. Boot the target computer from CD/DVD/USB.
C. Recover lost Dell Inspiron password with the burned CD/DVD/USB.

Hope it helps more Dell Inspiron PC users!
