Hey guys, I'm new here and I'd like to say thanks for all the knowledge on this forum first of all.
I am learning electronics repair, been fixing GPUs and laptops mainly until now, and I'm slowly trying to fix desktop motherboards now.
I had a few successes until now, but I messed things up with one of my recent attempts, namely a Gigabyte H410M S2 with which I burned my test cpu.
I had identified a mosfet which was burned, removed it, cheched for shorts and I didn't find any.
When the new mosfet came, I put it on the board and checked for shorts again and didn't find any....06-08-2024, 08:38 AM -

Originally I unlocked advanced settings in bios change a setting and bricked the laptop. I tried to learn all the settings which in future I still plan to learn with caution now.

I'm using ezp2023 and both bios and spi chips are

[FONT=Lato][COLOR=#141618]Bought from guy who has no need of bricked laptop
It would give a Power LED and a Charge LED but press the power on button and nothing not even a fan noise or anything.
Tried removing all hardware still nothing
Left the battery on charge all day, the next day it was only reading 3 volts.
Removed battery and still not even a power or charge indicator.

hello. I knocked off a capacitor on the apu (probably while cleaning off the thermal paste i guess). I have done some google search and i got 2 answers so I'm confused ( 1uf 0201 and 0.1uf (100nf) 0201). i think the ones above the missing are same value but i am afraid to remove it and check due to the tiny size, fear of losing that also; and also maybe scratching or damaging the apu. Anybody has actually measured these caps please help.Yesterday, 08:19 PM
