[user10002]

Hello
I have a lenovo T510 , board uma 08273-3 48.4CU08.031 with this problem:

when the pc enters windows the core suplly regulator u66 starts to make noise and oscillates the voltage from 1.2v stable to 0.9v , 0.8v and ends up restarting the pc, i have already changed the u66 (adp3212) the coils and the line tantalum capacitors , it did not solve , can you help please ?

Thanks
