Hello friends, today i got an A2485 820-02100-A in a desd state, found visual short on PPVIN_5VUSBC23 line, removed tantalum capacitor, installed same same value from other donor board, now there is no short on any of the rails but when i plug either magsafe3 or usbc inget 5v stable with 0.00 amps drown, no cycle, just these steady values, board is not in dfu mode, checked with magsafe and with usbc. Only value that i find on the board is ppdcin_aon which is 5v… i dont get 3,3 aon, 3v8 aon .. all missing, where should i start looking please !...

Hi guys,

i want to challenge myself to fix this graphics card- I know it's low value :-)
01g-p3-1313-kr (GeForce 210)
found 1 blown fusible resistor R56 ( already removed)
1 shorted diode D5 (already removed)
and i suspect short on U2 (ic itself isn't shorted)

i would like to know substitute diode and look at the diagram of that circuit....

Hi, I have some capacitors that I need to replace on a graphics card.

I've attached pictures for reference.

Please help me to understand the ratings so that I can order the correct replacements:

[B]1. G7 560 2.5E - I believe these are for vcore[/B][LIST][*]Is this 560uF and 2.5V?[*]What does the "E" mean?[*]Is there any relevance to the "G7"[/LIST]
[B]2. ECX 17 560 2.5V - I believe these are on the memory phase[/B][LIST][*]Another 560uF at 2.5V?[*]This is on the same graphics card. If the caps are rated the same as those above, why...

Hi

I have a 453 Mini , two of the four Sata ports are not getting 12V . I am wondering if anyone has knowledge on hardware repair on these devices . I have attached an image of the board , it appears the Sata ports are powered in pairs , the right pair are working , left pair no voltage ( 0.2V)


I have tried tracing the 12V rail , though have not been successful . I am guessing there is a Transistor or Mosfet that is open

Any help , perhaps a schematic?


The board otherwise appears to work fine .. Boots up ,

I have a Gainward GTX 295 with two PCB's which has a broken SLI bridge ribbon cable. As a result, the card is entirely useless and I'd really like to fix it if possible.

I've searched eBay and AlieExpress but haven't been able to find the part.

I believe this same SLI bridge cable is used on the Nvidia 9800 GX2 and the GTX 295 which both have two PCB's.

Can anyone help me on where to get a replacement SLI bridge cable please?

I want to replace samhwa RG 250v 1uf capacitor which has no ESR value and has capacitance less than 280pf.
It is possible to purchase WCAP-ATG5 in local electronic shop.
But I want to know that whether WCAP-ATG5 capacitor has similar or better quality than smahwa capacitor or not.
Is there anyone who has experience to replace any bulge or faulty cap with cap from Wurth Elektronik?

Now instead of DFU it says "Recovery"

A little back ground on this laptop. I was thinking of writing a topic on corporate laziness and irresponsibility.
We acquired a handful of laptops which a very large company wanted to have shredded due to sensitive information.

Since apple has NSA grade drive formatting I think this is inexcusably lazy that the IT department doesn't just target mode format the drives and release the MDM, and donate the laptops.

Hi guys,
I have a Gigabyte GTX 1080 G1 Gaming 8GB gpu. The earlier life of this gpu is unknown.

Fans are spinning on full speed.
All main voltages presents but gpu not detected by motherboard.
The voltage on pin 1 of the bios is constantly 1.8V

During visual inspection i noticed a brown spot on the top of the chip.
Maybe burned this GPU?

Does anyone have an idea where I should go next?
How do I check if the GPU is still alive?

This laptop came in as no internal display. I did see it boot on an external monitor but it was not consistent, however, the bios splash screen was consistent. The customer said it happened after a windows update. I tested the display and there were no signals on the LED_EN or PWM test points. At this point I decided to treat it as a bios issue. I disconnected the RTC battery and drained the residual power. After this, I did not get the bios splash screen anymore. The power led changes colour, fans spin, GPU and CPU get warm and caps lock is functional. I tried the bios from the Clevo repo, there...

Does anyone have a schematic for an HP ProDesk 400 G6 SFF main board?

I have one that blinks RED 5 times, pause, WHITE 7 times and repeats. This sequence isn't covered in the service guide. The closest is a memory issue but the one SODIMM is known/tested GOOD in another box (same model).

There looks to be some resistors(?) missing near BIOS flash chip.

Hi There

So I am looking for a part. Namely, a QqEEH. I beleive this is responsible to create the 3.3 power rail, but on my motherboard it is shorted to the ground. injecting 1 volt into the 20 volt power rail the IC heats up. Around the IC almost everything is shorted to the ground,
Anyone knows what this little controller chip supposed to be?

Thanks,...

Hi,

I'm currently experiencing issues with my Dell Inspiron 5415. Initially, the laptop would sometimes fail to boot, with the keyboard backlight turning on but no display on the screen. After repeated attempts to power it on and off, it would eventually boot up and function normally.

To troubleshoot, I removed both the main battery and the BIOS battery, but now the laptop exhibits a different issue: the fan runs at full speed, but the screen remains blank, and it doesn't boot up.

I suspect there might be a problem with the BIOS, and I would like assistance...

Hi, I'm seeing one 9V relay having temperature 40C on its 9V (primary) side. Does that seem right? I switched 2 relays on that board and the temperature was the same (on the same position), so I'm sure it's not a faulty relay. I measured voltage on that relay and it was 9.5V DC, so that looks good. I don't see any other relay on that board having that kind of temperature and they have 9V on them too.
I thought maybe the transistor that is switching this relay keeps switching on/off, so I also checked for AC and there was almost none: 0.3V using mV range. No steady frequency was shown, but...

Hello everyone, Due to a bad bios flash this Omen has a weird issue.

In the BIOS it says the ME version is 0.0.0.0 and when I try to update the BIOS it writes the bios region but when it reaches the firmware and ME it says it failed.

Tried HP USB recovery way and nothing worked.

I am kinda stuck, the main problem right now is the laptop would boot within 5 mins until the ME drivers load in windows and all works normally....

Hello,

This special tool from Apple is used to recover data from Macbook A1706. I've been using it for a while but it stops working. When connecting Thunderbolt 3 between the tool and working Macbook, Macbook should prompt "new device detected, allow or not"... but it doesn't.

Has anyone ever experience this ? It's not a cabling or power supply issue, some IC have stopped working but not sure which one. Probably the one that manager thunderbolt 3

I have an RTX 2070 Super from evga with a blown up IC. With the IC on the card, pin 17 had a short to ground. This pin is connected to the 5V rail by R993, a 0hm resistor. I removed both U610 and R993, to discover that the 5V rail has 800 Ohms of resistance to ground. After checking some resources online, i found a picture which describes the usual measurements a Turing series GPU should have in order to "work properlly". Interestingly enough, this gpu doesn't have U31, the IC responsible for the creation of the 5V on the card, as well as no L47.

I have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.

When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...
