Hey guys,
My name is Artem and I'm into old(relatively old) computers, early 2000's games and electronics.
Really enjoy tinkering with some tech stuff.
Now exploring the world of car ECU tuning using open-source tools (Romraider, Nisprog etc.), so bought myself a tablet, which has a locked UEFI.
That's how I ended up here)Comment

Hi! I ended up here because of a problem with my Lenovo ideapad 330s-14IKB. It doesnt want to resume boot. Checked Power Rail voltages, All seemed good. 8V, 5V, 3.2V, 1.2V. (Battery is 8.4V) But noticed a voltage drop on CPU rail from 1V to 0.6V then it restarts again in loop. Hope someone can help me find the schematics for this. ThanksComment
