[battery.12v]

i have this asus x541uv that power on but with no display ... so after reading its repair guide i found that the signal CPUPWRGD is not activated and the signal before it (PM_SYSPWROK_PCH) is activated ... do this mean that the cpu is dead ? how could i fix this ?? Thx

how much resistance is on CPU_Vcore coil?

how much resistance is on CPU_Vcore coil?

around 8 Ohms i dont think its shorted

for now i need to know from where this signal come cause its originated from cpu and its not related to any thing in the motherboard .. also i need to know when this signal Activate ... i searched on the net but i could not find so much info about it

If CPU_Vcore is high, then there is a high probability that PCH/CPU is defective.
Does the CPU get warm?

the laptop was taken from me when i will get it back i will test the cpu_Vcore, i found in some forums that i have to reflash the bios, do the bios play a role in the cpupwrgd signal ??

yes, I guess that is possible.

DRAMPWROK?? Check clock frequency at quartz. If clock is not working, then also cpupwrgd will not rise.

i could not find a signal with that name ... i just found DPWROK and its high ... and about testing the clock i dont have an osciloscope right now

No CPU_Vcore at all not even for a micro second ... resistance is 8 ohm but logically vcore wont be active till ProcPwrGd is Active so we need to found why the ProPwrGD is low
