We have 'General purpose', 'Audio' capacitors and more. Who dictates that ?

Re: Need help deciding what to replace my caps on my motherboard with.
No one.
A "Standard" means several companies got together and agreed they would all do 'something' the same way.
That hasn't happened in the Cap industry, at least when it comes to ESR.
GP for our purposes means not low ESR and that is determined by ESR [or Z] not being shown in the data sheet.
'Audio Cap' is an advertising thing that implies something special was done enhance the cap for use in audio equipment.
But, there is no Standard written down somewhere that they have to comply with to call their cap an audio cap.
The ESR terms are the same way.
That's why one has to look in the data sheets.
With audio caps the situation is worse because [if they did them] the things done to make caps audio caps aren't in data sheets.

Hey. I have a Fujitsu U757 motherboard with number CP732277. And i want to replace it with U758 motherboard like with CP755900 or whatever U758 series motherboard. U747/U757(7th gen CPU) all motherboards look exactly same so i'm sure it won't matter which one to use. But i would like to upgrade a bit and get U748/U758(8th gen CPU) motherboard. Motherboards all look exactly same layout as U747/U757, but i found one chip is soldered on U747/U757 which U748/U758 doesn't have. It is STM32F103 MCU which is near screen connector. And i'm not sure will U748/U758 motherboard will work with my U757 laptop....01-28-2024, 05:01 PM -
Hello,
I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.
My question is, can I update the Bios on this G733 motherboard to a G533 Bios.
The reason for wanting to do this is that the keyboard isn't working as it should, and I think this... -
Hi everyone 😀,
I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.
To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.
Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:- I already own the exact same model, but its plastic chassis is badly damaged.

Hello everyone,
I would like to ask if it is possible to replace the motherboard for the Lenovo Legion 5 16ACH6H NM-D562 with the NM-D601, which has a less powerful RTX 3050 chip. Has anyone tried this? NM-D562 is significantly more expensive than NM-D601.
Thank you.

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...
