Question about HP (228513001) Fan Kit
I have following problems:
1) When I press power button. It shows indicators blinking.
2) But the cooling fan doesn't runs as well as there is noting displaying in monitor ? What could be the problem.
This could be a bad power supply. When turned on do you hear any fan noise from the power supply. If not check and see if the power supply looks dirty of has a burnt smell. This could indicate a bad power supply.If the power supply is working, check all the connections to the motherboard for possible loose connections.This would cause a failure of the power good signal to allow the computer to turn itself on.When checking the connections check the motherboard for dust and dirt that may be affecting the operation of the cooling fan. Check the fan itself and check the motherboard for possible bad capacitors. These can be identify by bulging tops or bottoms. Check the main processor for the same dirt and dust problems and check to see if the heatsink is making good contact with the processor to cool it correctly.You may have to remove the heatsink and reapply thermal paste and reseat the heatsink itself to insure proper operation. You must also check the memory of the computer to see if it is seated properly and is functioning.You must use antistatic protection to check this out by ground yourself on some nonpainted metal object to discharge the body static. If you do not do this you could damage the memory and the processor if you must touch and remove them for cleaning. You should use canned air to blow all the dust and dirt off the motherboard and connectors.be sure to never due any cleaning or troubling shooting on your computer with the power connected. You amy also try to isolate a bad component in you set up by disconnecting all items in your system but 1 stick of memory and harddrive. Leaving all other components disconnected to see if the computer will start. Then connect each component back including the memory sticks to see if you get a failure again. the last component you attach before the failure will be the faulty one.If non of the above solutions help you may have had a motherboard failure and may have to replace it. Hope this helps you with your problem. P.S. if this is over your head then take your unit in to a service center and have them check it out for you.

A solid green light means the computer is operating normally.
A solid yellow:- the power is operating fine but your computer not processing data. This could mean there is a problem with the CPU or another component on the motherboard.
A blinking yellow light: power supply is receiving power from the wall, but not functioning properly. This generally means the power supply itself is bad and should be tested or replaced.
A blinking green light means the computer is in standby mode
