I wish everyone a good day, I have a lenovo laptop with water damge, I cleaned the motherboard and replaced the entrance mosfets ..
I have 19v and 3,3v and 5v ok.
Device draws 0.03 amps before start
The motherboard starts normally only once after 10 attempts and turns on.
When I press the start button, the power light turns on and the fan turns on and turns off again for 1 to 3 seconds.
When I plug in the battery, the charging led for 5 seconds turns on, then reset and the led turns off and on after 3 sec.
I tried new ram and keyboard but the problem still persists.
I removed he jumper between 5 VALW and 5vs, the power led work ok .
but when i reconnect the jumper the motherboard shuts down.
I applied 5 voltages to the 5vs line and did not draw any current 0.001 amps
I programmed main bios and the problem still persists.
thank you
