Any way to recover BIOS pass from a Samsung notebook?

[Medeiros66]

From nothing, my notebook started to ask for BIOS password. I tried some phoenix passwords, cleared (I suppose) CMOS removing battery, but… nothing!
It’s a Samsung NP 270E5E K01PT and
Disabled/hash Code: 3619C96C860D32BD73 (one of them, since they’re different every time).
Thank you for any help, guys.

have you removed the bios battery for 10 minutes, if it has one? sometimes you have to unsolder one side.

I don't know this model, unfortunately. There is also sometimes under the memory to solder points that you will have to jump. But I am not sure this model will have that.

Yes, I did, for about 30 minutes: nothing. More ideas for this model or similar?
Tnx.

As new as this laptop is, I would contact the manufacturer for a fix. They should be supporting this.

Does this model have a CMOS jumper on the under side somewhere?

If so if you short it the BIOS should reset.

I've searched for it, but I can not know what is. I've seen many others on Google but nothing equals the board of this model.

Look near the CMOS battery (usually, can be anywhere) for a set of jumper pads or pins. It can be labled RTC, JPW, JCMOS etc. This hardware reset is safer than a software reset IMO.

If no good check out Dogbert's blog: http://dogber1.blogspot.com/2009/05/table-of-reverse-engineered-bios.html

Dogbert says "Вячеслав Бачериков has also converted my scripts to javascript so you can calculate the passwords with your browser:" http://bios-pw.org/

I have seen there be two points, under the RAM on some, that you short to reset it. When I take the CMOS battery out, I always use a screwdriver to short the two sides, where the battery touches. Has always done an instant CMOS reset for me.

Sorry, guys: no evident pins or pads, neither some kind of suggestive label. I tried the “pwgen-samsung.py” algorithm, almost every kind of standard backdoor passwords too, as bios-pw.org online generator: nothing, nothing, and nothing. Too many hours spent around that machine…

I’m going to send it to the manufacturer, definitely.

Thanks everybody for your support and suggestions.
