Remove BIOS password

I posted an answer to this question which I felt was pretty good. The answer received one upvote then the next time I view the answer it is deleted with no information as to why.

Can anybody tell me why?

Note: Incase you can't view answer, here it is copy/pasted

I'd be very surprised if you can't get into the Bios. My first suspicion is always user error. See this thread for possible solutions to that specific part of your question/issue --> https://superuser.com/a/817932/465645

To directly answer your question, the first and obvious thing that pops into my head is to remove the CMOS battery and press the power button (Make sure the laptop has 0 power), this will reset the Bios to default factory settings. Note that your default OS may not boot correctly until your Bios is re-setup.

Here is a YouTube Video teardown of what I think is your laptop where he finds and removes the CMOS to reset the Bios. --> https://www.youtube.com/watch?v=lvphrUxiU_U

Update Re Comments:

I would say that my answer could stand alone if it was the following sentence alone. Am I supposed to provide step by steps instructions on how to tear down this individual laptop and/or not answer because I don't know this information?

  • General information like, removing CMOS to reset BIOS is useful for future readers.

"To directly answer your question, the first and obvious thing that pops into my head is to remove the CMOS battery and press the power button (Make sure the laptop has 0 power), this will reset the Bios to default factory settings."

Changes I will make that I have gleaned from comments/answer.

  • Never looking up YouTube videos to help compliment my answer via link

    Your answer was essentially a link to a youtube video. Links to videos are not good answers, as 1/ the answer is not self contained, 2/ the answer is useless if the video is removed. – DavidPostill Feb 11 at 20:38

    In addition the OP commented " the BIOS messed up setting might not be the only problem here, I've updated my question. + The video should not be used by people with little to none hardware experience, it might do more harm than help anyone." – DavidPostill Feb 11 at 20:39

    I disagree that it wasn't contained, the information was to remove CMOS and a video with his laptop, but what about other readers? Was the answer not useful? The top voted answer is basically the same, remove the CMOS. Also his comment is now not viewable. Ive never had an answer just deleted, I would think a down vote would be more appropriate. – FreeSoftwareServers Feb 11 at 20:46

    You were not even sure if the video was for the correct laptop ... – DavidPostill Feb 11 at 20:48

    "Ive never had an answer just deleted" apart from the other 2 answers that were deleted ... this and this – DavidPostill Feb 11 at 20:52

    @DavidPostill It was the best I could find with the information given... He gave a model number, I found a video with that model number but with extra digits on the end. Generally that means that it's universal for that model, but I wasn't 100%. I just feel deleting an answer is durastic measure and that my answer was good. I'd say better then the top posted answer as I gave basic instructions and linked a video with a detailed teardown. Clearly I'm not going to win an argument with you, I'm curious if you were correct in others eyes... – FreeSoftwareServers Feb 11 at 21:08

    @FreeSoftwareServers - If you needed additional information from the author, in order to properly answer the question, you should have asked for it by submitting a comment. Without the video, which could have been removed or made private by the YouTube channel owner at any point, your answer was not complete. – Ramhound Feb 11 at 22:24

    YouTube video might be helpful if you can also summarize the content. It's a simple rule to remember when posting a question/answer, always assume that all links are disabled/nonexistent to check if the post is standalone or not. – Andrew T. Feb 12 at 9:25

    What everyone else said, i.e. moral of the story: don't rely on information in external links for your answer. Your answer must be self-contained, which means that any pertinent information from your links should be quoted directly in your answer. – Jake Reece Feb 13 at 13:13

    Link only answers should be posted as a Comment. – Moab Feb 18 at 20:49

    Wouldn't the appropriate correction here not be to delete the answer, but amend it with the needed summary? – Atario Feb 20 at 2:29

In my albeit limited experience I have never had a CMOS pull NOT reset the Bios PWD.

The following answer is from another user from 2013 who has the same device NP300E5X-T02AE as the author of the question which you submitted your answer to.

I bought online code from ebay and it works now. the warranty service told me that bios IC should be replaced , replacing battery does not work on new samsung laptops.

enter image description here

As far as the statement:

“there is simply no (electronical) way to protect the bios against pulling out and put back in the battery.”

Yes there is. It’s called EEPROM memory which is set electronically.

EEPROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed.

I posted an answer to this question which I felt was pretty good. The answer received one upvote then the next time I view the answer it is deleted with no information as to why.

Flashing the BIOS does not typically remove a supervisor password from a BIOS. If it did then a malicious user, would have a pretty simple method, of changing the firmware settings. As I suggested in my comment to your answer:

Removing the CMOS battery does not reset the supervisor password most of the time.

Removing a CMOS battery does not typically restore the default settings resulting in the supervisor password being reset. If it did then, the supervisor password, would not be a very helpful security feature. Many others have said this in the past to past questions, so I am not alone, in not having much luck with removing a CMOS battery from a laptop.

Can anybody tell me why?

I voted to delete the answer due to link to the YouTube video. We expect answers to be self-contained, if the YouTube video were to become inaccessible, that part of your answer wouldn't be very helpful.

You also linked to two different resources, didn't quote and cite any information, so if the content were to change or be delete (in the case of the linked Super User answer) your answer would not contain the required information to answer the question.

The most important reason I voted to delete your answer, answers should only contain text and uploaded images, linked videos are rarely appropriate, due to the fact Stack Exchange does not provide an "upload video" functionality.

Unless you are quoting and citing relevant information from an existing answer, most of the time you should the flag the new question as a duplicate of an existing question, instead of just linking to an existing question's answer. This is, of course, is due to the fact we're not a forum so linking to "past answers" isn't actually considered to be an answer.

I've never had an answer just deleted, I would think a downvote would be more appropriate.

I actually did downvote your answer due to the fact it contained that YouTube video. I also voted to delete your answer because of the YouTube video. I normally assume a link to YouTube video is done to increase the revenue on the video itself. In my experience, an answer which contains a link to a YouTube video, rarely answer the question by themselves. Which of course is a problem for a website based on images and text.

Besides, you have had several answers, which were considered to be commentary, deleted due to them being commentary.

My guesses (I didn't delete it):

  1. The Superuser link you posted had already been posted by another answer (duplicating information)
  2. The answer couldn't stand on its own. When having links in answers, you should summarize the information, so users don't need to click around (possibly to sites that moved their documents or content) to get the information they need.
