I have huge problem which is driving me nuts. My laptop (Lenovo Y580) isn't charging well. It randomly disconnects AC adaptor. I'll try to discribe this situation in detail:
First time it was about 6 months ago. I was using my laptop without battery (i think i was playing Skyrim or something) and my laptop just turn off (immediately, just black screen and completly off at that point). I thought it was no big deal, so i powered up laptop again and enjoyed my gameplay. After few days it happened again. And it was happening often and often. Until my laptop started doing this even when i was using word or surfing the web or even wasn't doing anything. Then i plugged my battery in. What i realized, that my laptop just disconnect AC and at the front/bottom where the indication lights are, the solid white battery light (2nd from left) turns into blinking red/orange. So i plug off AC and stick it right back and laptop is charging again. But i can't do this everytime it happens, it is really frustrating and messes with laptop's performance.
Basically i can't use my laptop normaly. Somethimes it stays powered half of day without any faults (ofcourse i'm not talking about gaming, i forgot it long time ago), sometimes it disconnect charging 2-3 times per minute.
Here is what i tried to do:
-Clean everything inside my laptop (dust, dirt)
-Reapply thermal compound
-Power drain (when battery and AC isn't plugged and laptop is turned off, you hold power buttom for about 30 sec)
-Voltage check on AC adaptor
-Voltage check from AC jack to connection to motherboard
I can't find anything. So maybe someone encountered this problem or have a solution for this? I really need help Thank You
