Hello guys,
this is my first request in this forum.
I have this Laptop here with the problem that the onboard ram is gone.
Had to desolder the ram modules and of course it won't post.
Lenovo V155-15API
Model Name:81V5
Serial Nr: PF2125LC
MTM: 81V50004GE
Factory ID: JVHFC1
MO: PF9XB9B23174
Motherboard Model: FG542 FG543 FG742 NM-C101
Rev: 1.0
2019 - 05 - 07
Ryzen 3 3200U Model
First i moved the two resistors that controll if dimm only or soldered ram (pictures attached).
I tried deactivating the onboard ram in bios with spd removal tool 1.6 which won't change anything.
Later tried a RAM patcher from Badcaps but also won't work.
On the tool and the patcher there are 32 entries detected everytime and changed.
At this point i maybe have a corrupt bios too but i tried 4 different bios.
1. NM-C101.bin from Discord.
2. arcn37ww from Lenovos website.
3. nm-c101 onboard disable from a random russian website.
4. My original dump (V155-15API_old)
All of these are attached
Everytime i have run them trough the spd removal tool but no display.
Current draw 800-900milliamps (still searching for the onboard ram)
Maybe the spd removal tools and the patcher won't find all of the entries.
So can someone mod the bios for me so it won't search for other soldered ram instead just work from dimm only?
