Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
QZ2 and the rest of the same problem have been replaced. It does not exist for voltages

Re: Dell inspiripon 1545 WiFi cannot browse
Set the date and time of the computer from the BIOS settings.
The problem is not in the Wi-Fi card.
Replace the battery cmosLast edited by azhar2006; 04-12-2018, 04:32 AM.Leave a comment:

Re: Dell Inspiron 3521
Yes piernov I have replaced ISL88731C Was it the reason?Leave a comment:

Re: Dell Inspiron 3521
OK Mazorca and piernov
I found something when I removed PQ101 from the motherboard got the following voltages on the PQ100, the ideal voltages (1, 2 ,3), 19 volts, and get 7 volts on pin 4.
I think that (AO4407) is not equivalent to MOSFET (AO4409)
This is the equivalent...Last edited by azhar2006; 04-10-2018, 09:49 AM.Leave a comment:

Re: Dell Inspiron 3521
Thank You So Much Dear Mazorca
But do not get less than 18 volts on the gate PQ101
Is not ISL88731C the reason for it? Or is there a problem elsewhere?Leave a comment:

Re: Dell Inspiron 3521
Happy evening to everyone
Thank you so much
Yes, there is a decrease in the voltage from the other side from 19 volts to 18 volts on the PQ100, while the PU100 is originally not found on the motherboard, it has been removed from the mother motherboard because it is damaged and the presence of high temperature in it.
Where are the PR133 and PR139 resistance ?...Last edited by azhar2006; 04-10-2018, 03:26 AM.Leave a comment:

Dell Inspiron 3521
Hello all
I have a motherboard type (compal_la-9104p_r1.0) explained the problem in this picture.
The problem in PQ101 was damaged and I replaced it with a MOSFET bearing the number (AO4407A)
The resistors were measured and were intact.
Thanks in advance.... -
Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
So where do you think the imbalance?Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
Thank you my dear
The problem is the lack of fan rotation, only the glowing hand light, there is no pull of the current, there is only heat on the PCH.
There are no voltages 1.5
I had missed in (KBC) not volts at 116
What is Coz?Last edited by azhar2006; 04-08-2018, 03:11 AM.Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
You have replaced (QZ2) the same problem. It is a MOSFET(DUAL)
I noticed that lots of electronic pieces that hit their (SUSP#) signal do not work.Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
Good evening tibd
thank you very much tibd
Yes I will try to apply what you said to me after dinner .. And I will accompany you to report what happens.
Thanks again . Another question too.Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
raajkumar Intensive (PC216) and (PC218) were examined on pins pu200 yes I found (19v) and (5v).
I doubt the (SUSP),,Because when I raise (QZ2BA) the motherboard passes the voltage through (RZ4) to the MOSFET QZ1Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
Yes, there is a volt 19 volts but there is no outlet for the volt from the other end of the RZ4 and RZ13 0 volts ,, the SUSP voltage 3.3v in pin 116 for KBC

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
I found lots of voltages worth (5v and 3.3v) I can not get closer to pins PU200Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
tibd The Motherboard is just dead to a glowing LED lamp. No fan rotation or pull of the current on the screen of a power-equipped deviceLeave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
By checking on (QZ3) get a pin4 (16 volt) And it works perfectly....Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
Yes tibd (QZ1) and (QZ7) were found (+5VALW and +3.3VALW) and (B+_BIAS) are present (QZ3)
But there is no indication of the voltage on the pin4 to (QZ1) and (QZ7)Leave a comment:

Re: Dell Inspiron 3521 not (+3VS) and (+5VS)
thank you tibd
The 116 pin (KBC) was tested and there are (3.3) volts...Leave a comment:
