Hi I think this is a BIOS issue as all the power rails are there and just randomly will not display on its integral or external screens, powers up fans working heatsink getting hot, keyboard back light works briefly when in fault mode.
Attached is the BIOS that boots randomly when it works it works without any issues. only the escape key is lit when it plays up
Can someone please help me?

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. ThanksLeave a comment:

Hi Guys I hope some one can correct me and or put me in the right direction. I have a Dell Latitude 5430 admin password locked, i have read both UC2 & UC6 using pogo sticks guessing its something to do with the Dell Safebios, never had an issue with other models so far, with this Latitude 5430, uc6 is marked as a 25Q256JVEN but my programmer Xgecu proT48 will only give data in the dump if read as a 128mb if read as a 256mb it is empty also attached in the zip file, Any suggestions and resetting the me or password would be greatly appreciated.
