Hi all.
UMA version of LA-8241P here. System powers up with 7 beeps, which is usually a CPU error. I've tested the CPU and RAM in another known working LA-8241P and they are fine. (I can also use this board for comparison readings if need be).
My findings are that +VCC_GFXCORE_AXG = 0V but does not appear to be shorted at PL704. On the known good board this voltage is 0.8V. +1.0VGS/+VGA_PCIEP also appears to be 0V, but given this board is the UMA version I'm unsure if these should be present?
Here are some other readings I've taken of various CPU voltage and others suggested in a similar post. Any ideas?
VCC_CORE = 1.1V
VCCSA = 1.05V
VCCP = 0.8V
+1.5V_CPU_VDDQ = 1.5V
+1.8VS_VCCPLL = 1.8V
+1.5V = 1.5V
+1.5VS = 1.5V
+VCC_GFXCORE_AXG = 0V, should be 0.8V
+3V_PCH and PCH surface cap = both 3.3V
PM_DRAM_PWRGD = 3.3V
VDDPWRGOOD = 1.5V
PCH_PWROK, SYS_PWROK leg of UC1 (as I cannot find components on individual rails) = 3.3V
BUFO_CPU_RST# = 1.05V
PLT_RST = 3V
+3VALW = 3.3V
PJP804 (+VGA_PCIEP/+1.0VGS) = 0V
