To end off this sordid affair...
I contacted someone who deals in broken laptops, he asked for pics and I press the power button to show how far it boots.... guess what. The damn thing boots up like nothing is wrong with it. I can log into windows and the old documents are are still open like nothing has happened. Like its come back from sleep mode ?
This after I :
Hard booted it multiple times, removed the power supply and let the battery die multiple times, removed the SSD, tried booting with a new one, tried booting with no SSD, then the ASUS guys quoting me on both an SSD and MB replacement. They even claimed to have flashed the BIOS.
It just boots like nothing happened to it. LOL
I give up. I know its probably going to die again so not going to rely on it but wow... I have never seen anything like this before. Surely after all that its going to at least restart windows ?
When I'm brave enough to restart it i'g going to disable fast boot for sure because I rate that would have helped out a lot.
