Hi, the 1660 Ti in my laptop is currently power limited to 80W TDP. Would appreciate it if someone could teach me how to increase it’s power limit to let’s say 140W, have used pascal tdp tweaker on other cards but seems 1660 Ti is not supported.
Attached below are a full bios dump via SPI programmer, and a vbios dump via GPU-Z. Please let me know if anything else is needed. Thanks!

From where… do gonna re-route that 60w of power to the GPU… do have the schematics of the motherboard? Do you if the VRM circuit allows that…
People are just insanely unrealistic… a soft mod to get 60w from anywhere to a gpu on a mobile platform motherboard, unbelievable, better confirm that with LENOVO (how much juice they keept hidden from users).

EDIT: Then my apologies if sound so, it shouldn’t be that hard then, you’re quite right, stupid of me to think that a 230w PSU is not enough, good luck.
I have a 230W PSU, and I did the same mod on a Legion Y530 with similar total system power draw so it should be doable on the Y540 as well. Not sure why you’re trying to gatekeep people from modding on a modding forum?
No hard feelings my friend 
and thanks!
No… not at all, the issue here is not a PSU of 230 or 1000w, so good luck.
