Hello, I'm needing a BIOS reset password. The current halt code is 5C533F4A.
I have tried https://bios-pw.org/ and the results do not work.
Thank you.

Hi,
Your notebook is producing a hexadecimal halt code which is stored in ram as a 'one off' and will be re-calculated after a reboot. This indicates you have one of the later AMI bios's and unfortunately none of the current code generators will work for this - surprisingly, you can still remove a power on password from the machine by removing the rtc cell ( leave the power board connected ) then hold down the power button for 60 seconds before re-inserting the rtc.
The bad news is that the rtc is on the 'wrong' side of the system board so will require quite a lot of disassembly - see Page 115 of your Maintenance & Service Guide.

THANK YOU! That information helps a lot! =D
Not easy, but worth it as the unit ran out of warranty 2 months ago. Bought it without knowing there was an admin password and I'm trying to do nested virtualization which requires the firmware to have that turned on.
I can get into Windows....so there isn't a power on password. Will this method work against the admin password too?
Have a blessed day!

Hi Timothy,
You're welcome and yes, it should remove the bios admin password also.
All the best,

SUCCESS!!! Disassembled using service guide and YouTube video.
The only thing that was really weird was one of the plastic covers that covered a screen making the top plate hard to remove.
Replaced CR2032 battery while I was at it.
Upon power up, CMOS was reset clearing the password - toggled virtualization on.
Thanks again!
