asus fx 506l problem

[jboxer]

hi can someone help me, the laptop isn't power on and the only thing that I have found is that these component has no power consumption, what component are they? and what does mean that?

Re: asus fx 506l problem

its a SMD tantalum polymer capacitor. but i don't think its the problem check for shorts and check the buck controller in that vcore section.

yes you are right the problem was a short-circuit, but once I solved this ive found that there is two more short-circuit the coil that goes to the gpu power system and the coil that goes to the cpu power circuit are connected to ground but none of the components in the circuits gets hot when I inject voltage only the cpu and gpu a little bit, do you know what can be?

Re: asus fx 506l problem

Do you know that cpu/gpu coils is designed to show very low resistance to GND?

Give us exact resistance to GND on cpu and gpu coils. It may not bea short as you're assuming.

Re: asus fx 506l problem

Regarding the CPU/GPU: How much voltage did you inject and where exactly?

Give us exact resistance to GND on cpu and gpu coils. It may not bea short as you're assuming.

coil 1(PL1326): 3.2 ohm

coil 2(PL1226): 1.5 ohm

coil 3(PL127): 1.5 ohm

coil 4(PL128): 1.5 ohm

coil 5(PL1025): 8.7 ohm

coil 6(PL25): 22.1 ohm

i disoldered PL14 coil to measure the two coil pads and see the differences

coil pad 7(PL14): 0.9 ohm

coil pad 8(PL14): 7.33 Kohm

coil 9(PL13): 0.9 ohm

coil 10(PL12): 0.9 ohm

coil 11(PL15): 63.2 ohm

----------------------------------------

and now talking about the tantalum polymer capacitor, those that are beside cpu receives 20v and those beside gpu 0v and this was after resolve a short-circuit before those beside cpu was receiving 0v

thanks for all the help I appreciate the possibility to learn from everyone here.

0.9 to 2v and now I know that 2v is too much, could I have burnt the cpu and gpu? how can I know it?

and i inject the voltage in the pad coil that goes to cpu and gpu, the one that is 0.9 ohm in PL14 and pl1227 pad for cpu, the consumption was about 2.5 amps

do you think? so what is the file for?

Bios hhd not working

if its for programming bios, I don't have programmer to do it

2v i think you burn cpu and gpu

[jboxer]

Re: asus fx 506l problem

2v i think you burn cpu and gpu

how can I truly know it, do you know some technique?

Re: asus fx 506l problem

i think the cpu takes a lot of amps, 2.5 amps is too much. but if you had a problem with the cpu or gpu, I believe that the mosfets of the cpu or gpu would be in shorts

is that posible if I inject the voltage in the pad of coil that is not connected to mosfet? see schematics and where I injected voltage, if its possible that's a hope to save the laptop
