Hey there friends please help me..
I have been using it for a long time with window 10 and there was no issue. But today when i tried to turn it on on its battery power there was no ac adapter connected to it. It started up once but there was no display and the system light was lightning in orange color which supposed to be turned always to while color when pc is ready to start up and it took always 1 to 2 seconds.

I pressed and hold power button for couple of seconds and the Laptop was turned off. Then i turned it on again and still there was same issue. So, i tried to turn it off again. I disconnected battery and then again installed it again. Suddently after installing battery the while information button light tuned on and power button isn't working. I thought that it would be a kinda heatup issue so i left it for at least 30mins but issue wasn't resolved the white info button light is still turned on.

I disconnected battery and tried on AC adapter. when ac adapter is connected again the info light is on.

I disconnected the AC adapter too while battery is already taken out and i tried hard reset by pressing the power button for 20secs. Then i connected AC adapter to the laptop while battery isn't installed and it light up quickly the info light. And still its stuck on it.

I left it for 1 hours on the battery and the info button light is still tuned on.

I started checking inside
I opened it and remove inductors just to make sure that any of them is not causing shortage. Nothing happens so i put all inductors back. I didn't find its schematic anywhere but i now found it here. But it seems that solution is went out of my hands. I placed it for a long time it came to the original position when light were turned off i pressed power button and laptop worked and turned on. But after shut down it didn't turn on again. I opened it again to check the problem. I found U15 is heating up badly. (Is that a microcontroller? for what we won't find hex file to program it) if so then this means board is dead forever. If its common IC or something else like that ... please let me know what does it do? OR ANY OTHER SOLUTION YOU WANNA SHARE. i will appreciate your opinions. Thank You..!
