BIOS Password Locked/SOLVED For Dell Inspiron 15

I changed my bios admin password with help from Dell.  I have an Inspiron 15 3537 Laptop and had restart problems, so went searching, found bios info, called Dell Tech. They tried to help me, but would not give me the bios admin password. 

Yesterday, I found this link, read the info about not giving passwords out in the forum and scrolled down and found the option to email, so I did.

I told the gal who helped me my problem, she asked for my Service Code number and other verification info, then she asked for my error numbers.  One of the error numbers was my service code number, (find it on the bottom of the Inspiron, white sticker), which was in the bottom rectangle of the popup error box.  The other number was 16 digits and was listed above the service code number.  Note...I found the error code numbers a few weeks ago, and thankfully wrote them down from one of my bios errors while trying to set a new password.

She told me Dell would email me my Password to unlock my BIOS within 24 hours.  I received it this morning.

To reset the password, shut down the Inspiron 15, to restart in bios, press and hold F2 until it loads in the long rectangle box. 
The InsydeH20 Setup utility will open.
Arrow down to Locked Setup.
Press enter key and popup box will appear.
Type in the box the password you received from Dell.
Holy Mackeral...........It Worked!!!
Now you will see: Set Admin Password.
Press enter key, new box will open where you enter your new password.
Press enter, verify password, press enter.
Setup Notice box will appear exclaiming changes have been saved after you save and exit.
Press enter and it will ask Exit Saving Changes.
Please select YES
Computer will restart.
On restart, I received error message and selected RESTART.
It restarted properly..
There you go.
I hope I have helped someone with my instructions.
I was at the point that this was a no-fix problem.  I learned more about the bios than I think I needed to know, but guess I could say it was quite a learning experience at my age of 69.  Love computers, internet, technology and was born too soon!

Hi Alwaysearching7,

Thanks for your informative post on the Dell Community.  Hopefully others will be able to learn from your example.

The BIOS is locked and password protected so I cannot change anything in the BIOS because I do not know the password.   How can I reset the password?

See above.  Call Dell and be prepared to verify your ownership of the system.

I also have a BIOS that is locked after downloading and installing the latest version of BIOS. It is also an Inspiron 3537.

I went to the new version of BIOS after seeing that the Dell Support website "recommended" that I upgrade to the newest version.

I did not have a password in BIOS prior to this upgrade. As a matter of fact, my hard drive failed and I replaced it about two weeks before I upgraded the BIOS and during that process I had to make changes in the BIOS setup.

I tried your suggestion about emailing after reading the previous post that you tagged in your post. I also tried the interactive comments on the Dell support website, and I also called Dell support.

All three times I was told that since I purchased my laptop a couple of years ago and it was no longer under warranty, that the only way they can give me the password is to extend my warranty.

So let me get this straight, because I downloaded a recommended update after my original warranty had expired and this update came with a password that I didn't know was going to be included with the update, then I must purchase a warranty in order to access the BIOS setup on my laptop.

How is this different than a virus or malware program that infects your laptop without your knowledge and then when discovered you are demanded to pay a ransom to get full access to your own laptop.

Would one of the Dell employees that monitors these forums explain to me how this is a fair practice.

P.S. All I want is the password to unlock my BIOS. I am not looking for warranty support. I just want to be able to access the BIOS on my laptop that Dell has locked without my consent.

You do not need to purchase a warranty -- you DO need to purchase a "support incident" .  The US number to call is  1-800-288-4410.

However, if you are 100% certain no one set the password on the system, there is a very high probability you have  a bad mainboard -- the BIOS update by itself would not set a password.  So -- the warranty extension might not be a bad idea.  If the paid call doesn't solve the problem, and you wind up needing a mainboard, the warranty extension would cover that.

Your answer about a possible bad mainboard is exactly the same answer
provided by a Dell employee to another person who posted to the Dell forum
regarding the same issue.

Luckily for him someone provided him with a password that works.

I am absolutely positive that there was no password on BIOS prior to this
update. The reason I know this is two weeks prior to the BIOS upgrade my
hard drive failed and I had to replace it. During the process of replacing
the hard drive I had to make changes to the BIOS setup. I was able to make
these changes in BIOS without a password.

I have been reading quite a few posts on the Dell forum about people who
are having trouble with a password to get into BIOS. From I have read it
appears Dell is including passwords on BIOS updates and EXTORTING the
laptop owners into paying a fee to get the password.

All I want from dell is a password to unlock my BIOS. I did not agree to
have a password included with the BIOS upgrade. I am not asking for
warranty support or "incident" support. There was no incident, only a
foolish expectation by me that Dell would not try to rob me.

Search laptop BIOS password on the Dell forums and see for yourself that I
am not making this up. It is totally unfair of Dell to include BIOS
passwords on "Recommended" BIOS upgrades and then demanding payment from
laptop owners in order for the owner to be able to access and change BIOS

There are no passwords in BIOS updates. 

The facts:  If you want to have the password cleared, call the support line, pay the charge for the support call (NO warranty extension needed), verify your ownership status and they'll solve the problem for you.

You WILL NOT get free support once the warranty ends.

EJN63 you do realize that you just gave the game away right?

In your first sentence, you said there are no passwords in BIOS updates. In your second sentence you say if I want to have the password cleared, call the support line.

I am the owner of said laptop. I have proven to Dell that I am the owner of said laptop. I have interacted online, emailed, and had telephone conversations with Dell reps. I have been told in every instance to pay and we will fix your problem and that includes this conversation with you.
