Finally managed to find some time (and will) to replace my "temporary" ghetto full bridge rectifier, removed the diodes, soldered the new one (of course according to its polarity), powered the unit and after few pops the magic smoke escaped. Right, must have done something wrong, install a new one, check for shorts and bad regulators.. power on.. and again the familiar popping sound, but this time managed to cut the power before the magic smoke had escaped. After several hours of wild goose chase I found that the polarity of some of the brand new rectifiers was reversed.. so just keep in mind that everything is possible.
Aaand that is why I have trust issues..

by NagyeszI have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.
All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..
How can I extend its lifespan? Could reflow help?
It has ryzen 5 5500h, rtx 2050, no soldered ram.
Example of the artifacts:

by SkgodHey I am having Asus Rog strix g15 g513ih hn0865 and it's having display issues while running on igpu. Works fine when I open any game or whatsapp windows application. The issues are :
Black screen, freeze
The weird thing is that when as long as the laptop is running on igpu the problem keeps happening. But as soon as I open any game or whatsapp windows application, the laptop works completely fine.
When the screen freeze or black screen I used to move the display lid up and down and it usually works like that.
So can anyone tell me what would be the possible cause?... - Loading...
