Another nice video, Sorin. I just got a used Ebay Toshiba L15W-B1320 which was BIOS password-locked. I tried removing the battery for a day and shorting the JRST0602 pads on the motherboard near the Pentium and BIOS chip but neither worked. Later using a magnifier, I discovered another set of pads nearby marked JRST501. Shorting those for a few seconds did the trick and bypassed the BIOS password.

That method of clearing under the memory doesn't always work on this model. Hence the video to show replacement of bios chip

I have C660-1GK and have dismantled it few times by now. Thanks for the informative video! P.S. Yeah, my model's vent is always working even it's idle and been cleaned with fresh paste, so it collects dust extremely fast.

hi, bios chip is around the startup chip (super io) ATA ITE WIND BOND SMSC , On the new laptops, the bios chip is inside of the super io chip, check my other video, you will figure it out, Thank you, Merry Christmas

there is a way to remove a bios-password without changing the bios-chip, just by download the bios.BIN and programing with (Mini Pro TL866CS)...with this method you can remove a lot of bios-password laptop models, it's easy, excuse for english it's not my language, good luck professor.

I remember from one of your previous video's that you rewrote the bios software, using control B. Would this procedure not delete the bios software password?

No, i replaced the bios chip, but the old bios chip data has been loaded already by that big chip (next to the bios chip and must be reset by removing the battery). In this way, the big chip(startup chip who read the bios chip and start the motherboard) will read the bios chip again

thanks for your idea bro ! , just to know in newer laptops they are using new technology so you can't just reset your password by shorting 2 pins you must reprogram it using raspberry pi or SOFI sp8-A programmer specially that chips Macronix-Winbond.. it's the UEFI technology now , for any helps i'm here bro @@mirosawjarmuzewski2405
