This is a BIOS post, kindly post in a separate trouble shooting thread, I might be able to help you out there. Thanks dear for your understanding....

Thanks @ Markus1741 , appreciate your help. All good, yet to test the laptop by turning it off & on many times. Looks like the cleanup has cleared the problem.​...

Good morning friends., working on this Lenovo ThinkPad P14S., the problem with the laptop is that it freezes all of a sudden & then no display for a longest time. Sometime I get display & at times it is totally blanks. All the required voltages are present & taking around 20V 0.62 milli amps & when no display it is stuck on this amps. Hopefully a full BIOS cleanup might rectify the problem. Can someone do this for me., thanks in advance.
