Fan on Compaq Presario 3000 - model 3045US (by 2 users)
Someone is willing to send me his old Compaq Presario 3000 - model 3045US
laptop but there are some reasons why he isn't using it anymore. I won't
go into all of them. The most important at the moment is that it has a
seized fan which causes it to shut down when it gets hot. He has tried
to get into the unit without success. He is pretty knowledgeable and
has also searched for relevant documentation, but he writes: "I found
several documents that were close, but not exact. Some were useless
because they did not describe how to take it apart, others because
they did not match close enough."
If you know how to open up this laptop and replace the fan, please let
me know. Thanks.

I have a 5-year old Presario 3045us whose fan was extremely noisy and hot. I followed some of the advice posted here. I opened the computer, removed the heatsink and blew compressed air to remove the dust buildup. The improvement is dramatic. The disassembly and rassembly process is not too easy, though. Everything has to fit just right.
I still love this laptop because it is fastest. It did kill my hard drive after 4 years of use and just replaced it with second one. After cleaning the fan it seems to be running fine than earlier and not looking very dusty.
Just take all the screws out and then disconnect keyboard. Also make sure you have taken away the drives. Now you can separate the top and lower panel and access the fan. Fan has 4 screws and a 3 pin connector. if you unscrew it and disconnect it should be easy to replace.
Hope that helps.

Does not hurt to try. You may have disloged some connector, BTW.
Just check all that you can see when dissassembling and reassembling.
Apart from that I cannot really see how opening a laptop should
destroy it.

out all the screws and all the drives and the battery, etc., and what to
remove above the keyboard with a screwdriver before removing the keyboard.
I carefully labeled all the screws and their locations with matching numbers
and after removing a few realized that I only really had to remove 3, clearly
marked on the back with 2 arrows and 1 keyboard icon. Instructions for removing
the fan were under the keyboard. I removed the fan, found some padding inside
it which seemed to have come lose and gotten chewed up and removed it. Then
I put the fan back, the keyboard, the screws, etc., and tried to turn it on.
For some reason, it doesn't start. The battery light is permanently lit
and so is the light indicating power is present. I don't know how to tell
whether I destroyed it. There is also something rattling around inside. I'll
remove it and try again.
Maybe I'll just have to throw it out, but I might as well see what I can
learn from it while I have it. It is better than any of the other computers
in my possession.
Taking it back to the PC repair place isn't an option for various reasons,
and anyway, they are probably expecting me to return to them with an expensive
job instead of the roughly $40 job that replacing the fan originally
represented.
