Hello everyone, tell me where to dig already tired. It turns on only when the battery is connected, after I connect the charging, according to the multimeter readings, the charge goes on, there is no gong, the backlight turns on for a short time then goes out, I flashed the BIOS with a clean ME while preserving the old one, it didn't help, transferred the u7000 of another board just in case also nothing, removed the SMC there were suspicious contacts,then the SMC soldered on new balls, for example, after turning it on, it does not respond to the shutdown button, measurements showed that the keyboard is intact and the voltage sags. measurements after connecting the battery .
