I have recently purchased a Fujitsu laptop over ebay.
The computer does not start. That is, when I press the power button, the computer does not respond, the lights turn on for one second and then the computer turns off.
Then the wifi antenna indicator flashes three times.
The computer gets power and the battery is charging as the led indicators are stable.
I have tried:
-Reset (Holdin the power button for 30 seconds without the battery attached, and plug the AC adapter)
-Keep only one RAM unit in the first Slot.
-Disconnect the bios battery and reconnect it.
