Took battery out, RAM, Hard drive. Held power button and nothing.
Video card is the number 1 issue for Toshiba satellite models, need to reheat the mounting of the video card.
avoid disassembling the unit, what I did was.
*blow dryer (for the hair)
1.use the blow dryer to heat up the side of your Toshiba, point at the exhaust, located on the left side, do this for 35 seconds.
2.after using the blower, turn on the power button again and see what happens =D
hopefully it will work.
NOTE:
I had the same problem and it solved the issue.

Hi,
This could be a Power/Switch Problem.
Faulty Hard-Drive.
Solution:- Leave the laptop turned Of And charge the battery to Full Capacity. ( usually between 4-16 Hours ) depending on capacity.
This will also fully charge the CMOS ( memory battery )
then boot the laptop up, and see if this solves your problem.
If not i,d suggest running a scandisk or hard-drive diagnostic program, to ensure that you have no Viruses-bad sectors on the hard-drive.
If you need further assistance please don,t hesitate to ask for more help and advice.

Do the following without the battery inserted.
Let the computer sit with no battery for 24 hours. Do not put the battery in at all. Try using your original memory stick ONLY, with no hard drive and see if it will POST. If it does, insert the hard drive and try again. Could be the new memory...
Another thing you can try is reseating the processor. Turn the ZIF screw, take the processor out (WATCH THE PINS!!) and put back in GENTLY. Leave the memory in the computer, hard drive removed, try to power on.
These models have been known for bad motherboards. Contact HP and arrange to send it in. If you do enough digging on HPs website, you'll find the service advisory.
