A friend of mine brought me this laptop earlier which all of a sudden would refuse to power on, no life at all. Prior to the no power problem the laptop wasn't charging the battery which was put down to a failing mosfet but of no real concern until this problem came about. After researching the issue to death he bought a replacement motherboard which he gave me to fit this morning, however the system wont power on still which has left me scratching my head. So far I have done the following, Tested the RAM and GPU in my R4, both fine, unable to test CPU. Booting with only keyboard, power button and screen. Only keyboard and power button. Just power button. Power, CPU, RAM and GFX, Power, CPU, RAM, GFX and keyboard. There is no life at all, so I began research of this new problem and found the board behind the button could be the culprit or CPU since I am unable to check. Surely there should be power if CPU faulty of missing though, desktops and other laptops I have worked on will all show signs power with components missing or is this not the case with the M17x R2? Is there anyway to trigger the boot up without the power button? Any help will be greatly appreciated.
