T400 TURN ON PROBLEM DUE TO MOTHERBOARD?

2017-12-21, 17:55 PM

My old lenovo T400 (ccfl backlight, mobo 60y3757) suddenly  turned off completely . I cant tell if it was due to overheating or not. Anyway i  I  cleaned the fun, replaced its own cpu  with a  cheap new one  , applied thermalpaste and i also did the trick with 30 sec button push after i removed ac, battery and ram with no luck. No beep sound as well and also to mention two left usb ports are halted, only right works.  Only leds they started to turn on after all aforementioned is power led and Z and laptop still refuse to boot up normally . What do you think guys , is it a matter of dead motherboard and i have to give up, still a cpu failure (despite i changed it), or something else I am not aware of?
