Hi. I have an old Toshiba A135 laptop. When I press the power button, the hd activity light flickers for a second and then stays off. The laptop does not boot up or show any activity on the screen. The screen is completely dead. I also do not hear any activity from the fans or hd. I replaced the drive with another known good hd and it did not make a difference. I also powered it up with no memory and 1 stick in different slots - also no luck.

When it did run, it would always run hot. Not sure if the cooling fan went out, overheated, and damaged something. Any troubleshooting suggestions will be greatly appreciated.

Thank you for the response scout_03. I took the fan off and cleaned it out. Put it back together and still no go. When I hit the power button, the fan comes on for about 3-4 seconds, then turns off. The display stays dark and the power light stays green. No hd activity whatsoever - at least based on the hd led indicator.
