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?

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...

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?

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,

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...
