I've used my Laptop for almost 2 year. Lately, I have power issue. My laptop only charging when it's turned off.
When it turned on with battery and AC adapter, it's charging for 15 second, than its not charging for 2 second, than its charging again for 15 second, than it stop charging for good. when I unplug the AC adapter and plug it again, it's happen again and again. When the adapter is plug, the power light keep blinking.
I've tried it running just by AC adapter, it's of in just few second after I turned on.
