I shutdown this morning, unplugged it all, put it in my laptop bag, took it with me on a short journey and set it up again. Only this time, instead of booting up as it always did, it wouldn't POST. The power light came on and the fan was spinning at full speed and never stopped. The blue fully charged battery light was on and the blue power light.
Holding down the power button DID NOT turn it off, I had to disconnect the power and then the battery.
Tried again no dice. Removed power and battery, then bottom panel. Removed the mSATA SSD that I installed end of July. Tried again, same result. Removed original HDD, replaced mSATA drive and repeated. Same. Removed one memory stick, repeat, same. Replaced and removed the other, same. Replaced and removed DVD drive. Fired up. Started to boot but then I realized it was taking far too long and then boom it powered off by itself. Not been able to make it do that again since bringing it home.
Other information that may or may not be related: A strange powdery like substance on my screen after turning it upside down each time. Not really like dust, and since I upend this machine to dust the air vents regularly anyway, is not something I've noticed before. Might just be years of this and that but just don't remember seeing anything after cleaning the vents. A few days ago I could smell some unusual smell, and in the end I decided since I couldn't really smell it strongly from any wires or anything (or the fan exhaust) that maybe it wasn't my computer but was coming from outside.
Same thing happens if I power it on without power (battery only).
What are my options?
