My toshiba P105 laptop power light and power button comes on but nothing else?

Try to move your display back and forward to see if this is a connection problem between your mainboard and monitor. If nothing blinks on your screen while you shake it - then your monitor or mainboard went bad.... Replacing it will cost you more than you payed for the laptop... So it's better to buy a new one... =)))

First thing to do is to remove the battery and start the laptop with power adapter plugged in.
Did it start now?

Same results after removing the battery, nothing appears on the monitor

Is it running fan, starting HD, spinning up CD?

Yes, its running fan, spinning up CD but no hard drive light comes on. Shouldn't the first thing I see the F2 function to enter the BIOS, I don't see that

Carefully, wrap one end of a chain around the laptop, then wrap the other end around your bumber. Hit the gas! LOL. When you purchase a new laptop, get a usb drive enclosure for the type of HD that is in your dead one (IDE or Sata). IF the hard drive is still good, you will be able to recover your data. RKNetwork is correct. Can you hear the HD spin up when you turn the laptop on?

I also tried connecting an external monitor to this laptop but no luck in seeing text on the external monitor.

You are 100% correct, its a ram problem. Remove one of the ram sticks and it came up...

Super thanks for guiding me to the problem....
