ideapad 320-15ast (nm-b321) turns on sometimes with the reset (Novo Button)

mantza

this turns on one out of 10 times if you keep pressing the reset button, if it turns on it works ok for hours, i did bios update and nothing changed
the keyboard works ok, no water damage and the power button works if you keep pressing it to turn the laptop off everytime
what could be causing this?

Check cable length DC + 19V.
Try a shorter cable.
Check the basic + 3V and + 5V for these cases.

there is 19v on the dc jack (it does not have a cable) and it has all the + 3V and + 5V i could find

+19V примаяно напрямую к плате?

Even if present, the problem may be in the length of the power cable.

Had same problem. Fixed by replacing R114 to 20k (located under WiFi module)
