When I press the power button it turns on for only 10 sec., then shuts off. Screen is blank, no beeps, no error messages. When battery is installed the fan runs for a couple of seconds then fan shuts off followed by the laptop shutting off. When using AC only (no battery installed) laptop is on 10 seconds, but no fan. AC adaptor has been checked and is working fine. And also tried different outlets with no success.
The screen does not power on for the 10 sec. the only thing on is the power light.
