Hi friends!
I am trying to fix this Thinkpad x230 motherboard. It neither powers up nor charges the battery.
The issue is 3v/5v rail is missing because enable voltage EN1, EN2 for TPS51220 are missing. This voltage comes from Thinkengine ic TB62D515 according to schematic.
Anyone here knows how thinkengine ic works? Should I try replacing it?
Please advise.
Thanks.
