I am having trouble with booting up my 2000 Notebook I get a no operation system

[Brianmu04]

I recently purchased a hard drive wiring caddy because I was getting a (3FO) error message stating no harddrive I hook it up and now I get nothing power on my system and the light is white for power then it turns red shortly after. That is my problem thank you for a response if you can help. I am hoping it's not a motherboard issue

I'm not familiar with hard drive wiring caddies, but does this require you to open the case and connect some wires?

Sounds like it zapped the PC, so you should try to run Diagnostics by pressing the Esc key repeatedly while rebooting and then selecting the Diagnostics option, usually F2.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
Since your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:

If that link does not get you a useful page, then use the main HP link:
