Hi everyone,
First of all, I would like to wish you all the best in the new year.
I'm having a problem with my Lenovo Y700 laptop. Motherboard NM-A541 with i7 CPU. When I press the power button, the motherboard boots up, but nothing is displayed on the screen. The keyboard blinks and I can change the backlight sensitivity - that's it. I check all the coils and resistances are good and the power supply is correct. I changed the BIOS batch (several versions with pure ME) but nothing happened. 45 points on the imvp is 3.3V (that's VR_RDY). On imvp I have 1V on svid_alert, svid_data and svid_clk. I tested RAM socket through a tester and it is approx. I checked with a thermal camera whether RAM starts after CPU, but there is no reaction on RAM. Current consumption after starting board is 750mA Can I test next ? What can I do? Is the processor faulty? Please help me.
Have a nice day.
Best regards
