I have had my IBM Aptiva since 2000 with Win98SE. Never ever let me down, although the OS has, more often than not. I never used the hybernation feature until recently. It didn't work that well, but still I used it for half a dozen times. Everytime It came out of hybernation it would power-up with the hybernation window on the desktop and then go back into hybernation. On second power-up it stayed up and worked as usual. BUT, two mornings ago it failed to turn-on. The two LEDs just flicker. No HDD noise, no CPU fan, no PSU fan; nothing but the short flicker. I diassembled the PSU, cleaned it and looked for fried items or burnt smell; nothing. Was unable to test voltages as I do not have dummy load. Internal fuse had integrity and managed to read +5V on two internal leads. As all failed, I reassembled the unit and had another go. The PSU fan worked and thinking all is well, reintalled it. BUT, same problem again. Computer won't turn-on. Any help is very much appreciated. Thanks!
