Y50-70 Touch only charges when powered off

My Y50-70 touch will only charge and detect the power adapter when it is shut down. When on and running it acts like the power adapter is not plugged in at all. When shut down it charges the battery and the LED light indicates its charging but when its on and running it doesn't detect the power cable at all. I just wanted to know where to start to try and solve the problem. Its running windows 10, was Windows 8.1

Yes all except the BIOS. I cant update them because the installer says it can run n just the battery and tells me to plug the charger in, which it already is Smiley Mad

Would lower wattage and amperage psu cause this problem? The OEM psu is 135W and 6.75amps. The psu that came with the laptop when I purchased it is 65W and 3.25A. The guy i bought it from said it didnt have the charger when he bought it so he bought one and the computer had been having this problem since he bought it.

The PSU was the problem just in case anyone ever has this problem!

I am having this problem too. When you say the PSU was the issue, what was the solution? Did you have to replace it? Something else? Please expand.

 

After I plug in the charging cable, mine will take a charge after about 5 seconds and then after a second the power on botton, power (white) and battery (orange) indicator lights will flash simultaniously and it no longer takes a charge. They continue to flash until I unplug the charger.
