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.

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... -
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... -
first of all hello everyone
If there is a short circuit on the motherboard of the HP laptop. The CPU was broken (i3-10th) I found a donor motherboard on ebay and replaced the CPU.
The CPU on the donor motherboard had the OEM Hash key. But I did not check the OEM Hash key before ordering the donor motherboard.
Normally, after changing the CPU, the motherboard started and the white LED light on the DC jack was blinking.
The motherboard was in reset state and the current drawn was 60mah.
I checked the BIOS information and added the OEM Hash key on the donor motherboard... -
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.
