Did you run a bios updateand has an anti virus programme installed? If you did the bios is corrupt and stopping the system from running.
I would remove the RAM and Hard drive. Power up without the battery and look for error messages on the screen. Ensure the RAM is correct and place one strip in at a time.

SOURCE: toshiba satellite A60 no boot
We can only assume that because the cd drive operates then the motherboard is operating in part, although, the southbridge chip may be damaged, as the northbridge works memory etc. Maybe it is that the processor is fried as there is no fan and the system then shuts down. Toshiba are probably half way there with the answer, unless; they investigated further and decided it was not the processor but the motherboard.

SOURCE: Will not boot up
this is motherboard hardware issue
1) first all you need take out all devices like HDD DVD, wireless card then try turn it on if noting yet
2) change RAM stick that you have done
3) check DC PWM standby status, like 3V/5V/1.8V which should be appear before power on.
if no 3V/5V DC output, check this PWM circuite like MOSFET or PWM chip.
if you find 3V/5V, so need check 1.8V DC output and 1.2V that chip fail also cause nothing turn on.
all steps need diagram check where the chips and componenets on your board.
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question
