Inspiron 6000 powered down
In the middle of my UBUNTU upgrade process the Inspiron powered down, trying to reboot worked for a few seconds. I disassembled the laptop to the MoBO level, removed all RAM, removed battery, removed DVD unit, removed modem, removed LCD display, removed keyboard, removed CPU. So only a bare MoBo was connected to the poweradapter. Pressing Power ON resulted into the following:
All LED illuminate for 4 seconds, then power is down, this is consistent and can be duplicated with same results. Blower fan does not rotate during the power-up period. AC adapter is in perfect condition, same results with another adapter or with a fully charged battery.
After a 12 hour idle period with power disconnected and trying the above process again the all LED ON lasted for 10 seconds at first attempt. Consecutive attempts resulted again in exact 4 seconds. Keeping power-ON switch depressed makes the LED to cycle at 4 seconds interval.
Question: is there some logic built into the MoBo turning Power to Off after 4 seconds when certain latching conditions are not fullfilled?? Any ideas to trouble shoot?

The answer is yes -- if POST fails, the system will shut down after a short period of time.
Make sure the CPU is locked down into its socket correctly.
If that does not solve the problem, remove both memory modules -- do you hear two beeps at powerup?
If so, you may have bad module(s) or a bad memory socket.
If you hear no beeps without RAM installed, the mainboard is bad.
