hi all excuse me for my bad English but i will do my best i got Acer aspire 5310 no power after some diagnostics i find short at pl16 i change PQ40 but short still there . with my Power supply unit of my desktop computer i make a red wire on pl15 and i give 5v. THe pu10 (ISL6251) spoiled i change it.The short is gone and and the leds is on. I press on/off bottom after some second all led or off. no 3.3v nor 5v all are down . and on B+ the voltage is 4.4v that's not normal i change PQ30 (AO4407) The B+ go to 19.4v and drop to 4.4v i change PQ1 TP0610K. now all voltage are ok but leds are off. a think that i can not understand is a voltage on JP2 at pin 6 ON/OFFBTN is 17.4v i think on this pin(6) the voltage must be 3.3v. i need your help and your are the best who can do that. thank you very match. |
