Thank you all for your inputs. I did some further tests and it seems that the motherboard tends to boot (alien lights for 10 secs, then switches off automatically). When I insert VGA, it does nothing. Therefore I guess the VGA is dead. Will try with another one and will see. I'll share results later.

Thanks for your feedback and suggestions. I tried all the reset options and also I re-installed all the components to a new motherboard. Unfortunately no change. With battery in the power button (alien head) is flashing but the battery is really dead so it has no chance. Without battery it flashes twice only. When I press the power button, flashing stops, I can hear very little "clap" from the area where the power adapter is connected to the motherboard. But no LED lights or blinks, simply no activity at all. Adapter still glowing blue, I tried also another adapter, same. And I do have the crappy 260 GPU. But I assume if this is dead, the CAPS/NUM/SCROLL LEDs should blink, there are some error codes to show that. When you tried to replace components in your M15X, by a chance, did you try to run it without CPU or GPU? Did it anything or nothing at all? I'm asking because it seems to me that CPU could be the reason of this behavior. Battery charging works without CPU. But to activate motherboard, I guess only two components are mandatory: motherboard and CPU. If I disconnect all the other ones, motherboard should start and to show some error codes (see attached).

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
