Re: Test CPU without damaging motherboard?
The ceramic tan caps can short but I'd guess the chip itself is pretty much fried.

Re: Test CPU without damaging motherboard?
just for the records.. attached is a closeup of those "blue things" on the back of one of my Celeron Dualcores (E1200 .. my test CPU as you can clearly tell by the marks on the pads lol)
I could measure if they show resistance if you want.. I'm kinda curious what they are myself..Attached Files

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.

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... -
Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.
So here is what the motherboard looked like with its original caps:

To save you some time: the most important bits are in bold.Some further examples/explanations or to the side & in grey - you can probs skip them if it's TLDR for you. Sorry, I've got ADHD & tend to over-explain stuff - just like I'm doing right now 😅 Briefness is for poets not me 🙈
Please help!! 🎶I'm just a girl in a world that wants to scam me out of lots of money for any tech stuff/repairs 🎵 Seriously tho, I'm poor&I can't afford to get laptop diagnosis, especially if it ends up needing a new motherboard.
Where I live, all the tech shops are run by very...
