Hi, my M15x seems dead for no obvious reasons, simply one day worked, the other day not. No liquid inside. Battery is very old so I use notebook without it. The symptoms are that it does almost nothing. When I press power button, nothing happens. Sometimes, when I hold the power button, it blinks twice (the power button only). After some checks I suspected the motherboard so I bought a new one from ebay, reinstalled everything but it behaves the same. It could be faulty too but the probability to have two motherboards with the same issue is very little. I tried to run it without RAMs, with different AC adapter, no change. Now I'm guessing that the CPU could be dead. But don't want to waste another money just like that so I hope someone from you, experts, could face the same earlier and I can learn from it. Do you know how M15x behaves when CPU is completely removed? And what if GPU is removed? This could help me to isolate the origin of problem. Thanks, Martin
