Re: Asus N53SV Dead No Power
The closest one to RAM is 1.102V then working up to the fan is 1.095V, 1.094V, 1.097V. These are without CPU. Yes it charges the battery when connected (charging light comes on). No I am not able to reprogram the BIOS, unless it has a BIOS recovery mode
ThanksLeave a comment:

Toshiba Z830 blown component identification
Hi guys,
I have a Toshiba Z830-10Q that is dead. The motherboard is an FALZSY1 A3162A. A component is blown near the power input, its 6 pins and the first few characters look like "ACC". By any chance is it a Maxim MAX1697UEUT? I just found an image on google that looks very similar.
Many thanks,
Graham... -
Re: Asus N53SV Dead No Power
I have finally tried a new CPU now but it does the same thing still. The way it turns on actually reminds me of BIOS recovery mode, is this possible? As soon as AC is plugged in all lights come on and fan spins fast with nothing on the screen.Leave a comment:

Re: Asus N53SV Dead No Power
Okay, that is good news that your motherboard does the same with no CPU, I am just waiting for the CPU to arrive now. Thanks again!Leave a comment:

Re: Acer 8943G Accidental Short, No Power
Thanks for all your help guys, I ended up just replacing the capacitor with a 22uf 35V tantalum capacitor and so far it has been working for about 10 minutes! Really appreciate everyone's help here....Leave a comment:

Re: Asus N53SV Dead No Power
I have attached a few images. Also regarding the heat of the intel pch, voltage on the big coil near it is 1.5V although I have no idea if this is related

Re: Asus N53SV Dead No Power
Hi, thank you for the information, pin 7 is 3.373V with or without the CPU. CPU coils are 1V with no CPU, and a few mV with CPU. Hope this helps!Leave a comment:

Re: Acer 8943G Accidental Short, No Power
Excellent thank you all for the tips, I will give it a go tomorrow when i have the necessary equipment.
I think it will be PC256 since this is where the spark was. If so, this is a 22uF 25V 1210 capacitor. I have been searching for this capacitor and found a Murata GRM32ER61E226KE15L fitting the same details. However there are many different types, what does X5R, MLCC mean? Is a tolerance of 10% okay?Leave a comment:

Re: Acer 8943G Accidental Short, No Power
Hi smali,
Thanks for the comments. No the laptop is not fixed, it just works on battery, but something on the AC side has shorted making the adapter turn itself off.

Re: Acer 8943G Accidental Short, No Power
thank you meritosari
It is a capacitor thats looks damage, but it was my understanding that an SMD capacitor can not fail to short? or am I wrong here?Leave a comment:

Re: Acer 8943G Accidental Short, No Power
I have just tried to run the laptop off battery and it does actually still work! The battery was not inserted when I made the short.Leave a comment:

Acer 8943G Accidental Short, No Power
Hi everyone,
I have had an absolute nightmare this morning, I wanted to try to format an mSATA SSD in my personal laptop, so I took out the wifi card and put in the SSD, stupidly enough while the power cable was still plugged in, but then the wifi cable moved and shorted something and there was a big spark, now when the adapter is plugged in the light on the adapter goes off because something has shorted.
I could have sworn the wifi cable only touched some pins on the mini pci/msata connector, but looking at the motherboard it looks like the spark was on a capacitor... -
Re: Asus N53SV Dead No Power
oops I was just measuring resistance across coils not to ground, im reading 18.7 ohms and 11.8 ohms when the cpu is in, reading fluctuating MOhms ~ kOhms with no CPULeave a comment:

Re: Asus N53SV Dead No Power
this is hm77? how do I confirm that? apparently the current CPU, i7-2720qm is not supported then, its only 3rd gen i7'sLeave a comment:

Re: Asus N53SV Dead No Power
I am pretty sure the answer to this is no, but I do have an i7-720qm processor. The current CPU is an i7-2720qm, both of them are for an rPGA989 socket, so are they compatible? Could I put this 1st gen i7 in the N53SV?
thanksLeave a comment:

Re: Asus N53SV Dead No Power
resistance on all coils is 0 ohmsLeave a comment:

Re: Asus N53SV Dead No Power
The image attached shows the one that was shorted

Re: Asus N53SV Dead No Power
I removed the CPU, it doesn't make any beeps, but the fan spins strangely. it pulses on and off every second. Also the CPU coils all have just over 1V when the CPU is removed.. does this mean 100% the CPU is damaged? I really hope not, it would be expensive just to check as I need to buy another CPU..Leave a comment:

Re: Asus N53SV Dead No Power
I don't have a spare CPU to try but if we assume CPU is okay, then what? I guess there is no power going to CPU since none of the mosfets have a gate voltage.
If the motherboard was working fine and I remove the CPU should it make beeping noises or something?
thank youLeave a comment:
