Hello,can somebody remove my BIOS password? Service Tag: CYZKSG3

I tried 00FDAA / 00FCAA and 4000 lines hex "removal" with no luck (just black screen then off)

Thanks.

hi try unlock this file

I tried both of the methods, as I mentioned in first post, but it was not working. Wrote original, and again, it was not working. So, the the Ch321Programmer was the problem, used older version, write the first one (with 00FDAA method), then verify - verification failed. Powered it on anyway, and it worked!
Thank you.

Hello i think your bios backup is corrupt read twice again and verify it.

hi Markus1741 I have read the bios file in situ with pogo sticks and taken off board and read same result every time, is there any thing available that will get me out of this situation, like a generic bios, the machine fires up 1 out of may be 50 -60 so seems to be bios related. Thanks
