Hello people,
i have issue with my laptop, which i can`t repair alone. Problem is : laptop will not start, led light on the dc port is on when is connected to the adapter , after pressing the start button nothing goes on, no fan spinning , no lights coming on (except power port , which is always on). Sometimes (randomly) laptop will start just like that. After that i can use it as much as i want, i can switch it off and on , no problems. if i leave it for awhile off , then same issue, wont start again. I have it already dissembled , so at the moment i`m testing motherboard + lcd + power button + ram. From what i can check with the multimeter so far i can get 19.4v after the power port (picture 1), then at the start button i can get on the first 2 pins 3.33 but nothing on the rest of them. I`m not really sure if i do the measure as it should be done, so if you have patience to explain me how and from where i should start checking components on the motherboard i will appreciate any help, thank you in advance
