Hello everyone. I have a G751JY laptop that has 2 problems that i think are related.
Problem #1:
The laptop takes 20-25s to post, after that though it works flawlessly.
Problem #2:
Sometimes the laptop wont turn on, no reaction to the power switch until it's fully drained (which also resets bios config).
I've checked the schematics and boardview and i've traced the problem to what i think is the root cause of this issue.
Haven't completely figured out when exactly this happens, but i've got one scenario pinned down where i can reproduce it every time.
1. Turn on the laptop,
2. Wait for it to post and enter bios
3. When it's in the bios unplug the AC (The battery is dead/removed)
4. When replugging the AC the IT8585VG (U3001) doesn't have 3.3V on the EC_GPF1 net
I'm also attaching the boardview.
The IT8585VG datasheet is nowhere to be found, so i'm not really sure what i can do from here. I've read conflicting information regarding the chip needing to be programmed and not.
On the board there is also a Winbond W25X40CLZPIG which according to the information i've found should hold the EC firmware.
Any help with solving this problem would be greatly appreciated.
Thanks.
