Lenovo Thinkpad P51 Boot Not Showing Lenovo Sign



My P51 laptop boots up but does not show the lenovo sign. I'm aware of the power surge problem, where you disconnect the battery and power cord and then hold the power button for about 45 seconds.  I usually need to try this several times in order for it to work (while doing a cold reboot everytime). The confusing thing is that after 5-6 tries of what I just mentioned, the laptop eventually boots up as normal, and if I were to just restart the laptop everything would work fine.


I'm not sure what exactly is causing the issue here, is it the power supply or is it a problem with the mother board ?


Advice is appreciated.
