I have been using 12.04 on my Dell Inspiron 1525 for 6 or 8 months now and installing updates as they come along. Yesterday morning the laptop did not boot first time in fact I had to hit the power button several times before it booted then ran fine all day. Today it would not boot at all. Put in the live cd and it booted immediately. I read a number of threads that gave various ideas so turned off the computer to start checking hardware. Since then, no way can I get any sort of action. Is it hardware or software? Holding down fn key while hitting the power button gives me two solid lock LEDs and one - number 9 - is flashing. Have checked docking station, removed and replaced RAM chips, and done the static off and on trick all to no avail. Power light comes on, cd drive whirs briefly, then the power light goes off -sometimes it does stay on though. Has it done a post check? I don't know.
Any ideas would be greatly appreciated.
Merry Christmas BTW.
