ASUS UX390UA not starting
I have come across and issue I don’t seem to be able to figure out.
My laptop refuses to start, when the power button is pressed absolutely nothing happens. The issue appeared after I closed the lid to put it to sleep, when I tried to wake it.
The laptop has had it motherboard change under warranty twice but the the issue was caused by i the laptop would at least had LED flashing, which is not the case at the moment.
So far, I have tried:
-Battery disconnect and reconnect;
-Battery disconnected, power supply plugged in;
-Battery disconnected and power switch held for 30s+, then power supply plugged;
-New power supply.
None of the above has worked so far.
If anyone has an idea that could save this laptop, I am all ears.
Thanks for the answers.
@aactech: that has been done with no success. No light at all and the fan doesn’t kick in.
@jayeff: -I have tried holding the power button with power connected for 10s+ a few time already and that doesn’t solve it.
-The battery was charged, not sure if it was charging though. As you mentionned the USB-C seems to be the weak point as on every laptop relying just on this. Unfortunately I don’t have a multimeter available at the moment, but I managed to find a spare battery that I should get this week end which will hopefully narrow the issue to a few possiblity, ie old battery dead and/or no charge going through the USB-C?
So a quick update, I got a second battery and a voltmetre.
Both battery are at 7.6V for a 7.7B battery, so that’s pretty good.
I have checked continuity from the usb-c to the battery plug on the motherboard: there is continuity on the ground but nothing on the voltage ones.
When the power supply is pluged on the motherboard, there is 0.83V at the battery plug terminals
Ist dies eine gute Frage?
