Lenovo Legion 7 - Help Identify IC

[silver60618]

Hi gang, its a long shot, but working on Lenovo Legion Pro 7 motherboard NM-F091, and trying to identify this component near GPU with marking "eHFQH" that is burned and shorting the board. Looks like power management IC

I couldnt find any schematic or boardview. The CPU side also has same chip. Any way to identify this chip? or take measurements from the good chip to determine what it is?

Any help would be appreciated...

Hello,

Could someone help me out either decrypting the administrator password, or removing entirely? Password was forgotten by user.

I have an ASUS TUF A16,
laptop board number FA617-PMV-GBM / 6050A3460902-MB-A02.
Laptop is turning on but stay on with no picture, cpu is getting hot but gpu not, i found online photo of board and im attaching it - on the photo in upper right corner under wi-fi slot i have 1.3 ohm on coil after injecting 0.8v only part of gpu is getting hot that's why im suspecting faulty gpu chip.
All other resistances looks fine.
My chip have marking: 215-163000117
do you know if 215-163000047 or 215-163000007 is compatible with this gpu to replace?...

Hi all,
since my second device of this model number now died due to Canon being service unfriendly, I'd like to reset the counter myself.
This model of printer seems to be on non of the eBay sellers and other suppliers support lists for the Canon Service Tool. Other forums suggested the v5103 version of the tool, which did not work unfortunately.
Has anyone maybe experience with this exact model?
Thank you!

Hey mon2. I’ve got another crazy case for you that never happened to me before.

A2179 board, PPBUS_G3H short, 2 ohms.
injected voltage, 1V 5A limit, 200mA draw.
decided to increase to 2v, amperage draw instantly dropped to a few mA.

the resistance of the rail actually went from 2 ohm to 100 after that, and PPBUS went from 0mV to 700mV.

checked the resistance of the 4 current sensing resistors around the ISL, all fine. Removed the ISL, went from 100 to 160 ohm.

Replaced it, still 160 ohm.
Removed the 2 ISL mosfets. Still the...
