Help with component ID!!!(LA-J091P motherboard)
Hey guys, can anyone please help identifying components circled in green and their respective values/reference .
Board came in from another "Pro shop" and is missing components. Unable to find them in schematics (using the following as reference: [url]https://www.badcaps.net/forum/showthread.php?t=95414&highlight=LA-J091P[/url])

Re: IC compatibility?
Hi mon2, it's not the RTL8111C. It written REALTEK 8111C, sometimes listed as RT8111C. The pin count is different.
Similar to this: [url]https://shopee.vn/REALTEK-8111G-IC-m%E1%BA%A1ng-LAN-tr%C3%AAn-maiboard-m%C3%A1y-t%C3%ADnh-laptop.-i.72014335.7305583727[/url]Re: IC compatibility?<br /> <br /> ...Dnh-laptop.-i.

IC compatibility?
Hey Guys, I have a Lenovo AIO that came in for repairs.
One of the issues is a dead ethernet controller chip (RT8111C).
The only replacement I currently have is a RT8111H. Are the 2 interchangeable? I can't seem to find much info on the RT8111C.

Re: Weird but interesting issue with DELL 3542 (intel mb 13269-1)
For Not turning you should start with basic troubleshooting. Since you are getting 3.3 and 5V, that means you dont have a short on the main 19V rail.
Measure reaistance to ground on all coils and and post your values here. From the video you sent, you merely measured if the inductors have continuity through itself, which in this case is not helpful.
Set your meter to continuity, Place black probe on ground (you can use the USB port metal case if you want). Probe all inductors with the red...

Re: Weird but interesting issue with DELL 3542 (intel mb 13269-1)
How are you measuring the inductor? Continuity from 1 pin to the other or with 1 probe on ground?
Edit:
What is your issue actually? Not turning on or just slightly off voltage reading (but laptop working)?...Last edited by Spider1211; 09-16-2022, 12:10 PM.

Re: iPhone XS Data recovery from NAND flash
@repair schematics, thank you for your insight.
I was also considering scrapping up the top part to access the internals, but since I dont have any similar spare to practice on, i'ld rather avoid. I watched a video where this was successfully done on an iPhone wifi chip but cant find any info/pics of a decapped NAND.
Looks like this one will be going to trash.

Re: iPhone XS Data recovery from NAND flash
Yes, its encrypted. Am not looking at reading/accessing the user data on a PC but more to clone the data from 1 nand to another known good nand then resolder the cloned nand back to the board. Data will be accessed through the phone itself....

Re: iPhone XS Data recovery from NAND flash
It's called hope, lol But on a more serious note, I assume the power does not go directly to the internal array but through some other circuitry first.
Correct, the NAND is the storage. My hope is that, using an external reader, maybe the 2v63 power rail is not needed (since there are also some other IO power rails).
No, it's the NAND itself that is shorted since after removing it from the board there is no longer a short when measured on the board itself. But when measured on the NAND...Last edited by Spider1211; 08-23-2022, 07:25 AM.

Re: iPhone XS Data recovery from NAND flash
Watched a bunch of her videos in the past. I also contacted them, but its either send the phone or pay for forum. Since the customer is not ok paying for that, am not gonna bother.
The video assumes the motherboard is damaged but nand chip is still OK. In my case the motherboard is OK but the NAND chip itself has a shorted PP2v63_NAND internally.
Rephrasing my question: Is PP2v63_NAND required for an external nand clone?

iPhone XS Data recovery from NAND flash
Hey guys, I have an iPhone XS which came in as dead. The phone was not worked on before (I was the first to open it). After diagnosis (Splitting board, etc) it's confirmed to have a shorted PP2v63_NAND line.
Removed the NAND flash and short is gone on the board. Measuring directly on the NAND, there is about 2 to 15ohm to ground.
Is there anyway of backing up data externally in such cases (Client has some very important files and no back ups)?

HP Elitebook 840 G4 known good BIOS request
Hey guys, can anyone please provide a known good BIOS for HP Elitebook 840 G4,
Motherboard: 6050A2854301-MB-A01
Caps and F12 blinks at 1second interval (1 sec on, 1 sec off) for 5 cycles then stops. No display and fan goes to maximum. Already tried cleaning ME but no luck.
Motherboard looks very clean and all voltages are present and stable. Tried updating using HP bios update tool but not working either. I would like to rule out potential BIOS issue with known good working one.
Please...Last edited by Spider1211; 02-11-2022, 05:35 PM.
