I recently aquired a Dell Inspiron 6400 Notebook with Centrino Duo Processors and 1GB RAM.
Since new, I have had the problem that it won’t boot properly when it is cold (i.e. it has not been running for a while).
Within a couple of seconds of pressing the power button, the fan starts running flat out and the computer slowly boots. The fan does not quieten down, and the CPU usage stays at or close to 100%. If I try to do anything else it takes for ever. Sometimes the symptoms are worse: the taskbar is black, or parts of it are black, or the screen is pale blue.
If I turn it off and reboot everything is fine.
Naturally I have spoken to Dell support many times. They have replace the motherboard and the fan. The have got me to update the BIOS, and now just today to go back to an earlier version.
I have done a Restore back to the original factory settings. I have used MSConfig to disable all startup options.
Everytime I try anything, I can’t test it until the next day (or much later the same day iff I turn it off for a few hours) because the problem does not happen when the computer has been already running.
I think that when I next ring them tomorrow (if the problem is not fixed by today’s change of BIOS) they are going to give up on trying to fix it, and offer to replace it.
I would still prefer to fix it and so avoid having to install everything a third time.
Any suggestions?
