Hi, i have a lenovo n500 and it wont power on its actually really old but yesterday i tried cleaning its keyboards cause it wasnt working correctly because water entered in it and i tried cleaning it out but when i tried to plug in it powered and the fan was at max speed and no image but if i disconnected the keyboard everything worked fine except the touchpad so i tried plugging it back and i did now it doesn't even power on not even a sign of life no led nothing seems dead there is power in the power cable but it doesnt show that its plugged in so i don't have any idea what could be the problem
