I need help Diagnosing and fixing a motherboard for an A13 5g.
I'm experiencing some issues with my A13 5g phone, specifically with charging and powering on. I've already tried replacing the battery, charging port, and screen, but unfortunately, none of these solutions have worked. To troubleshoot further, I connected the charger with an AMP meter and found that I'm only getting 5v 0.02-0.08 amps, with the majority of the readings at 0.02 amps. Any suggestions on how to fix this issue would be greatly appreciated. Thank you in advance for your help!

Hi everyone,
I'm having a serious issue with my ASUS Zephyrus GA401I (4 years old, worked perfectly until recently). The system is lagging heavily, even in the BIOS, and is charging extremely slowly (a few percent in hours), making it nearly unusable. I suspect a motherboard or power delivery issue.
Symptoms:- Severe lag across the system, including BIOS navigation.
- Slow boot times and unresponsive performance in Windows.
- Battery charges very slowly (e.g., ~5% in 2–3 hours).
- No error messages or BSODs, just extreme sluggishness.
What I've Tried:- Replaced

Hello,
I need your help with an issue I'm encountering while diagnosing a NM-D471 REV 2.0 motherboard from a Lenovo laptop. The laptop won’t power on. I started by checking the power rails, including the main power line and the 3.3V and 5V rails.
I do have a proper 3.3V across the line, including at the chip responsible for managing 3.3V/5V—same goes for the 5V rail. I haven’t tried to simulate a power-on yet, since the main issue still needs to be resolved.
I have full access to the boardview, but I’m not sure what to check next to isolate the problem.

A very old client brought me a recently purchased notebook that suffered a lightning strike and stopped working, as in my region no one does plate repairs, he asked me to help him despite my little experience.
Acer Aspire Vero notebook (n20c5)
motherboard FH5AT LA k092p
The notebook turns on the motherboard LED but does not turn on the fans or even the video or any sign of life beyond that, I tested the power input, the power reaches the battery, I tested some components around the processor, some give 5.7v others give nothing and others are 19v, I haven't found... -
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.
