Re: Mosfet Identification
Alpha and Omega semiconductor strikes again.
It's pretty wierd as I am reading this I have the same model a Dell Latitude D510 on the bench now that crappy proprietary DC jack decided to fall apart.
It's got a very thin 3rd pin for data if the mobo doesn't recieve the data from this pin the battery won't charge but the laptop will run off AC very annoying.
Just got done removing the old one and ordered a replacement.
Be sure to check that jack out while you're in there if it's structurally sound check the solder joints. You don't want to have to deal with it later.Last edited by Krankshaft; 02-23-2009, 09:13 AM.Elements of the past and the future combining to make something not quite as good as either.Comment

You guys know your corporate symbols Thank you very much! Have you ever tried
moving the Maxim ds2502 from power supply to mother board?Comment

Re: Mosfet Identification
Someone needs to make a corporate logo id guide to make ID of things like this faster. Most of dell's line has that 3rd pin. Its very annoying when you have a similar power supply and it still refuses to charge the battery. I hate both the 3prong and the circle and center pin variety. At least its not as bad as the mac plug.Comment

I tried to use this method:
Testing an N-channel MOSFET:
Step 1: Discharge the Gate (turn off the MOSFET)
Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.
Step 2: Charge the Gate (turn on the MOSFET)
Now, place the red probe on the Gate (G) and the black probe on the...09-27-2024, 03:31 AM -
Hello,
My Asus monitor stop working today !! I found the problem on the main board, the power supply board is ok. It's Q9, a mosfet but I have no idea what are the specs since I don't have the schematic for that monitor !!
Can someone help me identified this mosfet ?
Thank you ! -
Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:
I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet... -
Hi Guys, I'm trying to identify that mosfet to replace it. Any help would be appreciated. I've checked the IC Markings and Datasheet section but I can't match the brand logo with any of the pictures. I thought maybe Alpha Omega because of the greek symboles or maybe Sinopower as the logo vaguely looks like an S...
It is on the motherboard of an Asus ROG G513QY (Motherboard ref: G713-6050A3254002-MB-A01).
Thaks!

Hi guys;
I need to replace two MOSFET's, the full number is
P21N03REOE4206; I have attached a Picture; Does anyone maybe know the UM? maybe OUM ? Logo for the manufacturer?
Please and Many thanks as always;...
