Hello friends,
On this motherboard, there is a broken connection between the RAM slot and the CPU.
However, it works fine with onboard RAM only — everything runs well.
The problem is: when I shut down Windows, the screen goes black but the system keeps running.
I have to power it off manually using the on/off button.
When I turn it back on, it works normally again.
I’ve tried many BIOS files from forums and other sources, but only the original BIOS works correctly.
I would like to thank in advance any friend who can help me patch...

Predator Helios Neo 16
Good afternoon, I have this machine and I can't install Sense. When I run the software, the message "This model is not compatible" appears. I've read that this is because the model name in the BIOS says:
PHN16-72-99PA.
It should say:
PREDATOR PHN16-72-99PA
Could someone help me change the model in the BIOS or tell me how to do it?
Thank you very much in advance.
Model: PHN16-72-99PA

Sonos Play 1 pulsing power supply
I'm rather new to repairing electronics, i do know the basics of most components but never actually repaired a PCB, but i want to change that.
So, i bought a faulty Sonos Play 1 speaker with the intention of finding the fault, and replace the damaged part.
Well, i did find the fault, i replaced parts that i thought caused the problem, but no-go.
The problem is a pulsing power supply, when i connect the mains to the board and hook up my thermal cam i see R306,307 and 308 getting warm, but i assume that's normal.
But, whats is not normal is the pulsing of resistor... -
Dell Optiplex 7490 AIO - red power led after flash
Hi guys,
This is my first post! 🚀
I have no idea what I’m doing, but I’m learning by trial and error.
I’m currently working on a Dell Optiplex AIO 7490—one of a bunch of AIOs that mysteriously failed to POST just a few days after the warranty expired. The original issue was that the PC worked fine until it was rebooted, after which it got stuck on a black screen (no backlight), with fans spinning at normal speed and a solid white power LED. Forcing it off by holding the power button would just cause it to switch on automatically and get stuck again on... -
Desbloqueio da BIOS DELL LATITUDE 3410
Boa noite, pessoal e o seguinte - Eu trabalhava como (contratado) para uma empresa que me forneceu um laptop Dell - Conforme a descrição a baixo - Concluí o contrato há mais de 2 anos, mas eles nunca solicitaram ou me enviaram instruções sobre como devolver o laptop, então ele ficou sem uso desde então. Acho que o prazo de prescrição expirou e gostaria de redefinir este laptop para poder usá-lo como um dispositivo pessoal.
Infelizmente, o BIOS está bloqueado, então não consigo inicializar a partir do USB. Consigo fazer login no computador usando minhas antigas credenciais... -
SVOD4 PCB pictures + parts
Hey, I find it very absurd that the SVOD4 costs so much and has zero documentation. I had no other choice than to buy it to unlock ECs, if there was any documentation or firmware avalible I could've made it or something simmilar. Anyways here are some of the most important parts:
STM32H723VGT6 MCU - It's a microcontroller by STMicroelectronics and its the whole brain of the SVOD4. It has flash memory for the firmware which can be updated by the SVOD4 program. Its also powered by the AMS117 which converts 5v into 3.3V. 7€ on AliExpress.

Ideapad 320 15ikb BadRam
Hi guys, I hope you can help me. I need to edit this BIOS and disable the RAM memory on the motherboard. It displays video randomly, both on the main screen and in the HDMI port. I ruled out that it was the cable or the screen. I did a RAM test and it shows the video. Thank you very much in advance....
