Question hp2540p does not power-up after fan cleaning

[dvrist]

hi all, i cleaned the cpu fan due to excessive noise. it does not power on after i put all pieces back again. i receive continuous white blinking on the power led when i connect the adaptor cable. i tried everything on hp support guidelines. i would appreciate if any of you have suggestions for this. thx..))

Without actually having the system in front of you to check, there is no way to know what happened or how to fix it. The only thing is that it worked before you took it apart, so first guess is something is not connected properly or got damaged in the process.

I appreciate your response. nevertheless, since i've repeated the things, i’m getting convinced that there’s something damaged and i should take it to a service shop..))
kind regards
