Could someone assist in removing the BIOS password from this binf file? I've tried and failed to follow the guides regarding AMITSE decryption !

Laptop is an ASUS X541UV - bin file and pictures attached.

Thanks for reading!...

Hey guys just wondering as to the purpose of these caps 560 but they seem to be shorted .. is it linked with the super low impedance of the CPU/GPU or do I have a short to search for ??.. the short is still there when caps have been removed.. sorry still learning really 😞.

This battery PCB is new but was put in not its original charger, and now the battery won't charge.
First of all BMS chip is without a name. It is 20 pins but no marking.
On this board, I can't understand where B- the line is connected to the board.
Any suggestions about the BMS Chip and other things to look for?...

[GoodCapacitor]

I have an old Mikrotik board with one bulging capacitor. It still works, but the cap doesn't look healthy.

I have tried replacing it, however it seems to ignore my soldering iron like it's a toothpick. I do suspect an industrial-strength lead used during manufacturing.

How do I remove it without damaging the PCB and (more importantly) surrounding components which might be more temperature-sensitive.

Hello everyone,
I have a problem with my Acer predator XB241YU screen. When I plug it in, the startup LED turns on instantly, and I can't turn off the screen without unplugging it.
After disassembly and inspection of the electronic cards I found what looks like a broken inductor, it is marked with the letter A and is at location L58.
In the first photo you can see the broken component, in the second photo you can see where it is on the board, in the third photo you can see the silkscreen and in the fourth photo you can see the identification sticker of the main board

Hi there,
I am looking for help with my broken 980ti. Had a bad DrMos (the bottom one) and replaced it, card worked for a short moment, but I got another shortes DrMos (second one) and replaced that one aswell.
Now I don't measure any shorts, I have 12v, PEX, 5v, 3.3v all working fine (probing points on card), but I can't get any voltage at FBVDDQ or NVVDD probing points.

Where could I check to find the fault?
You think my first DrMos could be bad, because I read that the first one will activate core?
Don't want to replace that one when I can just test other...

Picked up a used MSI Ventus 1660 super with no video output for $50 to dip my toes into GPU repair. After some lurking around here, google searches, and youtube videos, I've gotten around to checking resistances, and checking for the base and minor rails. On first inspection, I didn't any shorts on any rails, so I powered up the card, and found the 5v, 12v, 5v, 1.8v, and Vcore(I hadnt found the 3.3v location at the time). Later, after finding the 3.3v, I got a pcie extension and powered up again. This time I found the 12v. 5v, 3.3v, 1.8v, Vcore, and Vmem. Later, when I wanted to doublecheck my...

Hey all,

So I bought a second hand Powercolor Hellhound Spectral white 6700 XT a while back. The only problem with it is that the LED switch on the PCB is broken. Anyone have a PN I can use to solder in a a replacement? Also, a Boardview or schematic would be good too. Thanks

Hello, gentlmen!!!
My HP Probook 430 g2 does not detect battery. I tested the battery on another laptop and it is OK.
I believe smth is wrong with my PC ((.
Searching this forum I found some nice suggestions.
So, I tested Battery Connector pins (charger in/battery out) and here are my results:

pin_1 0v (-)
pin_2 3.30v
pin_3 0v
pin_4 3.38v (SCL)
[B]pin_5 2.55v (SDA)!!![/B]
pin_6 2.25 (+)

As far as I understand SDA pin must be ~3.3v???
Are there any other tests I can do before disassembling motherboard?

When plugged in (no battery installed), the battery light on the motherboard lights up and then turn off. When powering on, the same and light and the power button also light up in a white color but no output on the display. It stayed like that for a few seconds before shutting down. I also seem to ruined a connector that connects to the WLAN, 2 USB and audio board, the same board also have a melted 2062A IC. I will post pictures in the reply section

Hello all.

I am trying to repair a Gigabyte Z490 Aorus Elite AC motherboard that was roughly handled. It had some components ripped off the bottom of the board. The last two I am trying to replace are shown as CKA_FB1 and CKA_FB2 on the schematic and I think they are SMD 0402 30nH inductors to control the resonant impedance of the control rails. I have measured approximately 3.3VDC at CKVDD as per image below. On the board the still in place CKA_FB3 is 1mm x 0.5mm SMD component with a dark body.

I am not familiar with the symbols used in the schematic below if anyone...

I have this Sony MBX-273 on my hand. 19V present but no Voltage on 3.3, 5V Coils.

It has a [B]SN608098 [/B]Chip. When I check its pins It shows;
19V on pin 6(VIN)
5.3V on pin 4(EN_LDO)
3.4V on pin 5(VREF3)
1.3V on pin 1(VREF2)

But only 0.46V on pin 7(LDO)

Is this means Chip is gone?

I had problem with "Ideapad slim 5 16ABR8"
I believe 19V power line is shock to ground. M/B is not charging from Adaptor ( Adaptor is good ), Not sure about Power Jack but I like to make sure before changing the power jack. Laptop is on with battery but hot to touch near batter connection (Please see pic). I don't repair this board before and I'm beginner. Try looking for schematic and board view online but still no luck. Schematic or other help would be greatly appreciated.

Got this projector which has a problem with a lack of blue. Menu text is very yellow... expecting white. If I input a signal from a test disc via hdmi, a red screen image shows a uniform red as expect. Green similar while the blue does show but with non-uniformity. Looked at the in-polarizers. They are all good and clean. Running the projector to expose the light area in the prism block, shows each color well represented, all looking about the same intensity from the naked eye. Looking at the prism block itself and sending a light source back into the "out port", the individual...

Good evening, I've been stuck on a problem for a smidge now and not sure how to proceed..
Ps5 boots etc but just doesn't have any video .. put a new hdmi connector on and a new encoder.. and all the diode readings are good except
15- DDC clock - 671 - Iam getting 677
16- ddc data - 671 -iam getting 677
And hot plug (19) is 695 when should be 686..
Any ideas on what could cause this ? I have no knowledge of hdmi signals or EDM 033 board view to track where they go etc ..

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.

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...
