Hello everyone.
This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
I tried long pressing on the power button, after several seconds it would go off then when the button is released the power button light would flash for half a second but the charging light would still on - this light goes directly on when power source is connected - even the battery!.
Before completely going dead, sometimes when trying to force it to power on, only the fan would spin fast without anything on the screen or keyboard light.
I opened it, connected the charger and I could feel one coil (I guess it is one - 1R0 2127) would get a bit hot. (not happening anymore)
I have basic knowledge on electronics but I can learn fast.
I have a multimeter. a soldering iron...
Anyone can help troubleshoot this issue? I can work anymore since this is my main machine.
Please feel free to ask for more info and I'll provide them.
Best regards
