Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
If you get through the asking for a password ***** start up, and then asks again for a user password ***** Windows loads, then you have cleared the initial/power-up password, I think - or you know it already.
If you know it already or get through it otherwise, then you have access to the BIOS Setup. Go into the BIOS Setup then, and disable asking for a power-On password.
If I presume wrong about the problem, I apologize... but you did say you were getting to the Windows password ***** also. If so, the above ought to be possible, without any chip-shorting.
You cannot change a Windows password ***** BIOS Setup, of course.
Do you have the Power-On password, please?
If so... you should have control over disabling the BIOS Setup setting that enables the power-On password ***** the first place. Or at least power to change it to a 0-length password ***** will only require a RETURN key press after power-On.
If you do not follow the procedure appropriate for your BIOS Setup type/version, though, the change will not take.
E.g.: if you are required to enter first the current password ***** power-On, then the new password ***** want to change it to, then this has to be done exactly right or it will be refused.
E.g.: it may be in some BIOS Setups, you cannot disable the power-On password ***** one is set.
As for the Windows password... the chips on the laptop will never do anything about that. It is essentially on the hard disk, in the software.
Oh. That's different.
I'm not sure I can advise you further on this case, so with regret I must Opt Out.
(For whatever Expert takes this case: changing the power-On password ***** disabling it appears to depend upon getting into BIOS Setup. Windows password ***** user 'Sandy' also not known by questioner.)
