Technical Support Lenovo ideapad 330-15ich , no image

[user10002]

Hello
I have an Lenovo ideapad 330-15ich , model 81fk
board EG530 NM-B671 REV 1.0

it turns on but does not give the image the consumption is 0.60mA, I already programmed the bios and it didn't solve it, he has an nvidia N17P-G0-A1, do you know if this model usually gives a gpu problem? I was thinking of trying to disable the ram memories or even the gpu before reballing the gpu, what do you advise? can you help?
Regards

Once I received one of those with a fault similar to the one you indicate, the problem was a bad video cable (shorted), I suggest you disconnect that cable and try if it turns on.
On another Lenovo of the same model, on the TOP side, there was a shorted 3-pin transistor that enabled the nVidia GPU (discrete board).

A BIOS should be programmed when all rails and ACPI states on a motherboard are healthy, i.e. not shorted.
I suggest you use the ignition block diagram in the schematic before flashing a BIOS or EC, if that's the case do it before checking this, always revert the ROM to stock firmware (do a backup first).

I hope it helps you.

Good luck partner!
