the small power supply was burnt out,even I have replaced the fuse. The
fan
does not turn at all. I have replaced my client with acer power supply .
She
is happy with the arrangement. I do not want to fix the original power
supply. It is very dangerous.

how to fix this?



Throw it out. As you have replaced the PSU and completed the job, there is
no need to waste your time fixing a PSU which may have multiple failures
like shorted bridge rectifier, shorted switching transistors, high esr caps
etc etc. Do yourself a favour and save yourself the hassle.
