After alot of fiddling around and testing hardware i came to the conclusion it was a faulty raid controller, i changed it out with one of my old ones and boom boot took around 3 minutes with no errors.
Hi! I just got a T420 from my work and it has around 17T storage installed, 192gb ECC Ram installed and 2x 2.20 GHz Quad-core intel xeon installed, now it worked fantastic at work but now when i try to boot it at home it takes around 3 hours just to get passed the initilasation screens where you see whats on the system (bios boot i think people call it). and even after 3 hours when it enters me flash drive where i have my bios (unraid) on it says auto launching in 5 seconds... and tics down 1 second maybe after 2 minutes so takes around 10 minutes for that to fully launch and then nothing happens (and yes i have timed every boot), any idea what could cause this? i also had an error saying "BAT0015 Low perc battery" and could that be the reason why the boot is so insanly slow and non functioning?
T420 3 hour boot time
