Thank you for your answer!
I removed all the modules. I attached photos of the board.
What I circled in red looks burnt, and sparks are detected from it when the charger is connected and that part is touched with a metal.
circled in yellow are parts I suspect have burnt signs.
How should I measure the current consumption in standby? connect the board to the charger, and measure what with the multimeter?
(sorry about the newb questions...)...

Hi,

I have a [B]Lenovo IdeaPad 3 15IAU7[/B] that suffered water damage. It doesn't turn on (white power light flashes when on button pressed), and the [B]amber light flashes[/B] when plugged in.

Symptoms:[LIST][*][B]Short detected[/B] – sparks appear when touching the charging port connection with board with a metal (even a multimeter probe).[*][B]Visible damage[/B] – after cleaning corrosion, I found [B]4 possibly [/B]burnt memory chips near [B]PC3165[/B], labeled [B]UD5, UD6, UD7, and UD8[/B].[/LIST]
What are my next steps to diagnose and possibly repair it...

Hi everyone,

I'm Joel, and I have a background in [B]computer repair and hardware troubleshooting[/B]. I enjoy diagnosing and fixing electronics, especially laptops and desktops. Recently, I've been working on a [B]water-damaged Lenovo laptop[/B], which led me to this forum.

I'm here to [B]learn from others, share my experiences[/B], and hopefully contribute where I can. Looking forward to great discussions!

Thanks for having me!
