Asus TP412F - No Power
[ATTACH=JSON]{"data-align":"none","data-size":"full","data-attachmentid":3268557}[/ATTACH] Hi All,

Had a coil which was shorted to ground. Injected 1V and watched this ic get hot under thermal cam. Removed the IC and the short was gone. Now its .3 voltage drop which is good.
So basically i need help identifying this IC.

Lenovo Ideapad Gaming 3 15IMH05 - BIOS REQUEST
Hi all,
I've got a Lenovo ideapad gaming 3 15IMH05 with a black screen issue. I've tried a BIOS file which i saw in another post and changed some things in a Hex editor.
So i transfered the DMI info from my original BIOS to the one i got from the post. Flashed it to the chip and the laptop was booting again but very slow post.
After a couple of boots it went back to black screen again. Tried to flash the same BIN file on it which i used before but its staying at the black screen now unfortunately.
I hope someone can help me out. Attached is my [B]ORIGINAL... -
