Re: Dell Precision 5530/XPS 9570 no reaction
I've gotten it to start with a dead bug 16pin bios chip, with VCORE and DDR4_DRAMRST#, VCCGT is missing but apparently that's normal?
Problem is it doesn't stay on it just starts then fans spin a little faster, then it goes off, nothing on screen.
The ec seems healthy, battery light and front leds work, and even detects no ram properly
Could this be signal integrity issue with my deadbug bios chip?

Every voltage is present until PCH_PLTRST#, but I'm able to run the D key display tester
Another thing I noticed before I replaced the bios chip was that the CLK pin would go high for about 2ms and just drop, I'm guessing it was waiting for the chip to...Last edited by Windows8RTMUser; 09-11-2023, 10:48 PM.
